Background to the invention

IPC class H01R 13/53 covers base plates or casings for high electrical demands IPC class H01R 13/533 covers base plates or casings for use under extreme conditions such as high temperature, radiation, vibration, corrosive environment, pressure.

For the purpose of making electrical and/or electronic connections between different components, wires or the like, connectors are known to be made up of a plug element and a plug element. For example, there are ordinary sockets into which plugs can be plugged, which are attached at the ends of wires.

In the case of relays, fuses or the like, it is also known to place on a device a base into which the fuse or the relay can be inserted.

Even when it is a question of connections between circuit boards and plug elements, it is common to place a socket or plug on the circuit board or even elsewhere and then connect the plug with the circuit board by means of wires.

EP 1.069.651 A1 reveals a metal connector inserted into a contact hole of an electrical circuit substrate and making an electrical contact at the contact hole. The connector has a plug element that engages the substrate at the rear end of the contact hole, preventing further insertion of the plug into the contact hole. A distance avoidance section engages the substrate at the front of the contact hole to resist undesired retraction of the connection. The distance avoidance section is thread deformable to allow it to pass through the contact hole while the connection is being inserted.

However, studies of such a metal connection have shown that the apparently ring-shaped spacing section is easily plastically deformed when introduced through the contact hole and is therefore often destroyed.

In addition, the connector shown in EP 1.069.651 A1 is poorly handled by a user. In particular, if several contacts are to be made simultaneously, this requires the application of a very large manual force to carry the distance avoidance section through the contact hole, which quickly overwhelms the abilities of a human user if a sufficiently high holding force is to be achieved in the introduced state. Furthermore, the mechanical load acting on the boards is according to EP 1.069.651 A1. A larger one is also not possible with such a system according to a socket-stick method, as high plastic deformation of the distance avoidance system occurs.

Description of the invention

The purpose of the invention is to achieve an improved connection of a printed circuit board with a plug device.

The task is solved by a plug-in device for electrical connection of a conductor to a circuit board by direct insertion of the plug-in device into a contact hole of the circuit board, by a plug-in arrangement, by a plug-in semi-trailer made of a foldable material, by a connection arrangement, by a process for electrical connection of a conductor to a circuit board by direct insertion of a plug-in device into a contact hole of the circuit board and by a vehicle with the plug-in device according to the independent claims.

An embodiment of the first aspect of the invention describes a plug device for electrically connecting a conductor to a circuit board by direct insertion of the plug device into a contact hole of the circuit board. The plug device has a mounting area for attaching the conductor to the plug device. The plug device also has a transmission area for transmitting a current from the conductor to the circuit board. In addition, the plug device has at least three single-pin elements that can be inserted into the contact hole together. Each of the single-pin elements extends from a common body of the plug device and runs separately from the other single-pin elements. All the basic single-pin elements are independently elastically arranged and are optional when inserted into the opposite direction of the plug.

In another example, a plug-in arrangement is created with a plug device having the characteristics described above and a moulding tool, the moulding tool being designed to operate the plug device locked to the circuit board in such a way that the plug device locked to the circuit board is unlockable.

An example of an embodiment of another aspect of the invention describes a connection device to the above-described plug-in device and the circuit board.

According to another aspect of an embodiment of the present invention, a method is provided for electrically connecting a conductor to a circuit board by direct insertion of a plug device into a contact hole of the circuit board. According to the method, the conductor is attached to a fastening area of the plug device. At least three plug elements of the plug device are inserted together into the contact hole. When the plug elements are inserted into the contact hole, a plug connection of the plug device to the circuit board is provided due to independent elastic deformation of the plug elements to the base body. A current is transmitted from the conductor to the circuit board via a transmission area of the plug device. All other features are optional.

In accordance with another exemplary embodiment of the invention, a vehicle is described which is fitted with a plug-in device or a connecting device having the characteristics described above.

The electrical connector shown here can be connected to the circuit board by means of a direct plug into a contact hole in the circuit board (soluble). The contact hole of the circuit board can be connected through and, for example, have an electrically conductive coating, so that a current transmission can be provided in this area. By directly plugging the connector into the contact hole of the circuit board, a so-called direct plug technique can be used, in which no buckles or other aids need to be attached between the connector and the circuit board. Thus, the connector by means of the direct plug technique can lead to a simplified structural protection, since only a second layer of protection is necessary.

The circuit board can be essentially flat and have only the contact holes and their contact surface. In this case, flat soldering components may be present. In other words, direct soldering technology also allows to save entire housing (and the necessary tools) by casting or coating the assemblies and thus being fully protected mechanically or chemically. While traditionally a complex bonding of three-dimensional components such as the plug-in sockets, the pouring or painting of a 3D surface or a selective welding coating process is necessary, a simple bonding process could be invented with the contact hole containing a soldering iron and a process for the complete de-inking of the soldering iron and a suitable bonding or coating process is provided.

The plug-in device can be inserted directly into the contact hole of the circuit board (through-contacted) as described above. In this case, at least three plug-in elements are inserted together into the contact hole. The plug-in elements extend from a common base of the plug-in device, especially in the direction of the contact hole. The plug-in elements consist, for example, of plug-ins or plug-ins and can be distinguished, for example, by the fact that each plug-in element has an extremely small diameter in relation to its length.

The connecting device is connected to the circuit board in a direction of insertion, in particular the insertion elements are introduced in the direction of insertion into the contact hole. The insertion direction is essentially defined parallel to the direction of extension of the contact hole.

The insertion elements are introduced into the contact hole in the direction of the insertion direction, and the insertion elements are deformable in such a way that they are elastic or flexible to the base body, so that the insertion elements can be deformed elastically in the direction of the insertion direction.

The force which attempts to bring each elastically deformable plug into its original position is transmitted to the conductor by the plug on the inner surface of the contact hole, thereby creating a force which causes a high friction and pressure and provides the connection (e.g. pressure connection) of the plug to the contact hole or to the entire plug device with the plug elements.

The direction of extension of a plug element can be understood as the direction in which the plug element extends from the base case. This means that at least two of the three plug elements do not extend parallel to each other, but at an angle, in particular between 0 and 90° to each other. The plug elements may be in different directions of extension from each other or not parallel to the plug. When the plug elements are introduced into the contact hole, the plug elements can be compressed and inserted into the contact hole.

The plug-ins can be designed to be elastically and reversibly plugged into the contact hole, for example with forces of up to 10 Newtons. This allows a reliable connection to the inside surface of the contact hole and a good handling. For example, the plug-in device or connection arrangement is suitable for automotive applications, for example in tractors or buses, whereby a mechanical fixing of the plug and the conductor plate is made possible according to the invention. The connections can transmit strong currents and withstand high mechanical loads at the same time. They can be plugged by multiple forces at the same time.

In particular, the device in the present invention shall have at least three connecting elements which can be inserted into the contact hole. A number of three connecting elements or more provides an improved support and current transfer between the device and the circuit board. At least three connecting elements, which can move independently of each other, in particular, ensure that at least two connecting elements are inserted into the contact hole and provide a connecting device (e.g. a press connection). The use of only two connecting elements may result, in particular in the case of irregularly shaped (e.g. round and edged) contact holes, in the installation of only one connecting element on the top of the contact plate, such that no stable connecting device is available in relation to the device and the connecting device is not capable of being moved.The addition of at least a third plug-in element increases the likelihood that, even in the case of poorly shaped contact holes, at least two plug-in elements will be scattered in the contact hole, so that a stable and secure connection can be provided. This leads to a qualitative improvement in the value of a plug-in device and a reduction in the likelihood of failure, for example a reduction in the risk that the plug-in device will detach itself from the plug-in.

The connector may be provided, for example, by means of a press connection, whereby the press connection may be so strongly formed by the insertion elements as to provide vibration-resistant mechanical protection; the connector may also be provided and adjusted by the degree of elastic deformation of the insertion elements and/or by the retention forces of the insertion elements.

Err1:Expecting ',' delimiter: line 1 column 55 (char 54)Thus, in order to achieve vibration robustness, the mechanical connections of the plug-ins, in particular with regard to material, dimensions, attachment forces of the plug-ins, etc., can be designed in such a way that the corresponding vibrations do not lead to unwanted detachment of the plug-in from the circuit board. The plug-in and in particular its plug-in elements can be designed to achieve vibration robustness in accordance with ISO TS 16750, in particular ISO TS 16750-3. ISO 16750 defines a standard for mechanical load requirements for railway vehicles. To achieve vibration robustness, the connection can also be designed to meet IEC 60512-42 requirements, in particular at least one sub-requirement of IEC 68.6 (sinidal fire protection),The test results shall be presented in accordance with the requirements of the relevant technical documentation.

In another exemplary embodiment, each of the connecting elements has an insertion section. The insertion section is the section which is inside the contact hole when the connecting elements are inserted into the contact hole. The connecting elements extend together from a base of the connecting device separated from the other connecting elements, so that each of the connecting elements has a free end.

The end section containing each of the plug elements may, for example, extend beyond the plug section of the plug element so that, in the plugged state of the connector in the contact hole on the opposite side of the base body relative to the printed circuit board, the end section protrudes from the contact with the free end of the plug element.

Furthermore, each plug element may have an intermediate section between the plug section and the base body. By means of the intermediate section, in an exemplary embodiment of the invention, the base bodies cannot be directly on a surface of the printed circuit board, so that in the direction of insertion the plug elements first have the intermediate section. Then at the intermediate section in the direction of insertion, the plug section of the plug elements extends, which is completed, for example, by the final section of the plug element.

In another exemplary embodiment, the plug-in section has at least part of the transmission area, which means that the current transmission between the conductor via the plug-in device to the circuit board is provided by a contact of the plug-in section with the inner surface of the (through-contacted) contact hole. The plug-in section of the plug-in element may, for example, be coated with a conductive layer. Furthermore, the plug-in elements or even the entire plug-in device may consist of a conductive material, in which case, in particular, areas not intended to transmit current may be coated with an insulating layer.

The convex surface is formed in particular on the side of the connecting elements, which in the plugged state of the connecting elements is oriented towards the inner surface of the contact hole. The convex design of a surface of the connecting sections allows the contact surface between the connecting element and the inner surface of the contact hole to be directed. Thus, the force (pressure force, spring force) can be concentrated on a smaller area, namely on the area which is in contact with the inner surface of the connecting element by means of the connecting elements.

In another example, at least two of the three inserts are at least partially connected to each other. By being connected, two inserts can support and stabilize each other, providing a higher mechanical load capacity. Despite being connected, two inserts can still move freely in the further directions and spread out at different points in the contact hole.

In another exemplary embodiment, at least two connectors are spaced by a gap; the connectors separated by a gap can deform elastically in the direction of the gap, which allows the connectors to deform elastically in the direction of the gap during insertion into the contact hole, so that the connector can be inserted into the contact hole by means of the connectors.

The insertion elements form so-called spacing-releasing thighs. The opposite sides of the thighs can be optionally curved, for example, convex. This curvature can avoid unwanted spreading of the thighs when in contact with a flat surface.

The base may be raised or raised at the base, so that the base is in contact with the base, for example, in a larger diameter than the hole. The cross-section of the base may not be passed through the base, so that a base may be automatically provided. The base may also be raised or raised at the base, so that the base is in contact with the base, for example, in a larger diameter than the hole.The main body is not necessarily attached to a surface of the circuit board, but is simply the contact area of one of the connecting elements. Such a contact area as a positioning aid can intuitively facilitate a user to make the connection between the connecting element and the circuit board in a correct way and thus avoid electrical malfunctions. The contact area is thus used to limit the insertion of the connecting device into the circuit board. The contact area or spacer holder can define a minimum contact area between the connecting plate and the connecting device, thus preventing, for example, unwanted electrical contacts or the overloading of a signal through a gap.

In another exemplary embodiment, the input elements are parallel to each other.

The elastic deformability of the insertion elements can be achieved by having at least two of the three insertion elements have a gap between them, whereby these insertion elements can deform elastically in the direction of the gap.

In another exemplary embodiment, each of the input elements has an extension direction, with the distance between at least two input elements along their extension directions being constant.

In another exemplary embodiment, the end of each insertion element has a rounded surface, which, unlike a edged end surface, prevents any dispersion of each insertion element when introduced into the contact hole, for example because a rounded surface can find its way into the contact hole by itself.

In another example, at least one of the inserts has an expansion at one end of the connector, the end section having the free end of the inserts and protruding out of the contact hole in the direction of the insertion when the inserts are inserted into the contact hole. The expansion is formed at the end section in such a way that the expansion curves or gets stuck with a surface of the circuit board when the inserts are inserted into the contact. The expansion can be formed as a lifting hole and form a back cut that extends essentially perpendicular to the insertion. In other words, the back cut can extend parallel to the surface of the main contact surface and somehow descend into the contact surface of the insert.This can be achieved by preventing the expansion from moving the plug in the opposite direction to the entry, by attaching the expansion to a surface of the circuit board and thus preventing further movement of the plug in the opposite direction. For example, the plug-ins can be compressed during insertion into the contact hole so that the cross-section of all the plug-ins, including the expansion, is smaller in diameter than the contact hole. When the plug-ins are inserted into the contact hole, the top plug-ins move back into their original position due to their elastic deformability, so that the press connection between the plug-ins and the contact hole can form.On the opposite surface of the circuit board, the connecting elements may protrude with their terminals from the contact hole. In these terminals, the expansion is formed, which intersects or is jammed with this surface of the circuit board, thus preventing the release of the connector against the direction of insertion. The dislocation or jamming may occur if a cross-section of the connecting elements, including the expansion, is greater than the diameter of the contact hole, so that the connection is prevented from being disconnected. Thus the mechanical connection between the connecting device and the conductor plate is prevented. The dislocation or jamming of the expansion with the conductor is soluble due to the elasticity of the platform.For example, if the plug is to be detached from the circuit board, the plug elements can be pressed together again, essentially perpendicular to the input direction, so that the diameter of the plug elements including their extensions is smaller than the contact hole.

In another exemplary embodiment of the present invention, the expansion has a first surface, which is on the surface of the circuit board when the plug is inserted into the contact hole, and is so designed that the first surface is at a sloping angle between the plane of the first surface and the plane of the surface of the circuit board when the plug is inserted into the contact hole.

Err1:Expecting ',' delimiter: line 1 column 43 (char 42)

When the connecting device is moved in the opposite direction to the direction of the entry, a force is transferred from the circuit board to the first surface, the inclined surface, via a point of contact between the circuit board and the expansion, which results in an elastic deformation of the connecting element towards the centre of the contact hole. The deformation of an insert with the cross-sectional area depends on the force of pull with which the connecting device is pulled in the opposite direction to the entry.a flat first surface with an angle to the plane of the surface of the circuit board of essentially 1° to 10° (degree), such that, for example, the plane of the first surface is formed almost parallel to the inner surface of the contact hole or perpendicular to a plane of the surface of the circuit board, results in a lower force necessary to release the insert from the intersection. A steeper angle, i.e. an angle at which the intersection surface is almost perpendicular to the inner surface of the contact hole or nearly parallel to the plane of the circuit board,leads to a greater force that is necessary to pull the plug out of the contact hole.

In another example, the cable is attached to the mounting area by means of a clamping connection. The clamping connection can be provided, for example, by the connecting device having two clamping straps which can be bent around the cable to transmit a clamping force to the cable and to attach it. The straps can, for example, be plastically deformable. In particular, the mounting area is designed so that the cable can be attached to it by means of a clamping connection according to EN 60352-2 or DIN 41611.

In another exemplary embodiment, the input elements are so designed that the connecting device and the circuit board can be connected by the connecting device with a mechanical load capacity according to ISO 16750, in particular according to ISO 16750-3.

In another exemplary embodiment, the connecting elements are designed to connect (together) the connecting device and the printed circuit board with a mechanical adhesion force (e.g. produced by pressing and expansion) of at least 100 N (Newton), in particular of at least 200 N, and further in particular of at least 300 N.

In another exemplary embodiment, each of the insertion elements is designed to be capable of being inserted into one of the contact holes with a force of not more than 10 N (Newton); in particular, all the insertion elements together with a combined force of not more than 10 N may be designed to be able to be inserted into a contact hole in the direction of the insertion.

In another exemplary embodiment, the input elements are designed to provide an electrical load capacity according to ISO 16750-2.

In order to make the device of the invention applicable, in particular, to vibration-sensitive and high-current automotive applications and the like, in addition to or as an alternative to meeting the above industry standards, the device or connector may be designed to be compatible with IEC-60512-6 (Quick temperature cycles according to the printed standard), in particular IEC-68-2-14 (dry heat). It may also be designed to be compatible with tests under different climatic conditions according to the IEC-60512-6 and IEC-60512-1 NO standards (see in particular IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray), IEC-6812-2 (cold spray) and IEC-6812-2 (cold spray) and IEC-6812-2 (cold spray) (cold spray) and IEC-6812-22, the device may also be equipped with a gas cyclimate (cold spray) or a gas cycold spray (cold spray) in combination with IEC-6812-2 and IEC-6812-22, IEC-6812-2 and IEC-6812-22, or IEC-6812-22, respectively.

In another exemplary embodiment, each of the connecting elements and the transmission range of the connecting device are designed to have an electrical load capacity of at least 5 amperes, in particular of at least 10 amperes, and furthermore of at least 20 amperes.

Err1:Expecting ',' delimiter: line 1 column 55 (char 54)in particular, the high current-resistant design of the plug may be such that the transmission area, in particular all the plug elements together, can withstand cumulative currents of at least 50 amps, in particular of at least 100 amps. The high current capacity of the plug may be considered to be given if the plug is capable of being connected to a vehicle battery and can supply fault-free current from the vehicle battery to the connected circuit board. In particular, the high current capacity may be considered to be given if the transition resistors comply with the requirements of IEC 6012-25 standard.

The plug-in has at least three additional plug-ins, which together form a first group that can be inserted into the contact hole. The at least three additional plug-ins form a second group that can be inserted into another contact hole of the circuit board. The additional plug-ins can have the same physical properties as the single plug-ins described above and extend further from the same core of the plug-in. This makes it possible to provide a connection with a single plug-in to a variety of plug-ins. In particular, there is the possibility that more conductors can be electrically connected to the plug-in, the first group of plug-ins can be arranged in different electrical circuits. For example, some plug-ins can be arranged separately to form a single electrical conductor and some electrical conductors can be arranged in a second group.

In accordance with one example, a plug-in may be made from a single punched and bent electrically conductive plate, which makes it possible to train the plug-in with very little effort, since no other components are required except a metal plate or similar.

According to one example, the connector may have two pairs of connectors, i.e. at least four connectors. In other words, at least four, especially exactly four, can be provided. Each pair of connectors may be identically formed. Two connectors of a given pair may be arranged directly next to each other, only separated by a gap, starting from the base body. Two connectors of a pair may be structurally differently formed and work together.

In other words, a main surface of one main element may cover a whole corresponding equal-area main surface of the other main element, and vice versa, thus creating a compact and at the same time extremely stable structure which can also be reliably and precisely introduced into a single contact hole.

According to one example, at least one of the plug-ins may have a locking mechanism designed to lock the plug-in device to the circuit board when the plug-in device is passed through the contact hole; in other words, it may be sufficient to plug the plug-in device through the contact hole of the circuit board, which makes the locking mechanism self-acting on one or more of the plug-ins, i.e. without the intervention of a user, which locks the circuit board, thus providing a high level of user comfort.

According to one example, the locking mechanism may be designed to unlock the connector from the circuit board when the plug-ins are pressed together and when the connector is removed from the contact hole. Thus, a reverse motion sequence for locking, i.e. pressing the plug-ins together and then removing the plug-in from the circuit board, can allow easy unlocking. Such a locking mechanism may have a reversible characteristic, i.e. it can be essentially unlocked or unlocked as often as desired. This is achieved by a plastic unlocking characteristic that avoids the deformation of the plug-ins and instead of the plastic deformation of the plug-ins, the plug-ins are deflated and deformed during the unlocking process.

According to one embodiment, the first of the inserts may have an insertion section or be composed of an insertion section located inside the contact hole when the inserts are inserted into the contact hole; a second of the inserts may have an insertion section located inside the contact hole when the inserts are inserted into the contact hole and an arc section extending from the insertion section back through the contact hole to the insertion section of the first of the inserts and separated from it by a gap; the size of the gap during the insertion of the inserts into the conductor plate may be reduced first and after the inserts are removed from the conductor plate. The first and second inserts may be stacked together in a straight line.

According to one embodiment, an endpoint of the arc section can be carried through the contact hole by spring when inserted into the circuit board and can be carried back through the contact hole after springing, which makes the connector lockable by means of the endpoint on the circuit board. While the arc section is carried through the contact hole, it is compressed inwards by a lateral boundary of the contact hole. When exiting the circuit board, this compression force falls away so that the arc section can be carried back outwards, and thus ensures locking.

According to one embodiment, a concave area of the arc section may be adjacent to a convex area of the insertion section of the first of the insertion elements. The first insertion element may be designed as a convex arc. A corresponding concave area of the arc section is arranged relative to the convex first insertion section in such a way as to avoid mutual hooking and to allow mutual sliding.

Err1:Expecting ',' delimiter: line 1 column 61 (char 60)

According to one example, the arc section may have two opposite longitudinal sections connected by a curved arc opposite the insertion sections of the first and second insertion elements. The two longitudinal sections and the arc connecting them form a substantially U-shaped structure, which allows the spring effect and the mechanical stabilizing effect of the second insertion element.

According to an example, the connecting device may have a third and a fourth connecting element, one of which may be formed like the first and another like the second connecting element; therefore, the above design of the first and second connecting elements applies equally to the third and fourth connecting elements.

According to one example, the second and fourth connecting elements may be axisymmetrically opposite each other, the axis of symmetry being a longitudinal axis of the connecting device running along the gap between the connecting elements.

The second and fourth connectors may be in contact with each other, i.e. the second and fourth connectors may touch each other along part of their length, which has a stabilizing effect. At the same time, this contact allows a spring-like compression of the second and fourth connectors during the insertion of the connector into the circuit board. It is also possible that part of the first connector touches the fourth connector and that part of the second connector touches the third.

The above-mentioned devices provide a contact element with a fork press and a self-locking function, which can be used in many technical fields, for example in the automotive, industrial, computer and telecommunications sectors.

A connector according to an example of a model can be used to connect fuses, connectors, relays, capacitors, resistors, varistors, etc. directly to a circuit board and to lock each contact element by means of a self-locking mechanism.

By folding a plate-like contact element, for example, formed as a plug-in device, two movable legs can be obtained, which move outwards when plugged in.

This can save on connector interfaces, eliminate the need for a secondary lock and create a cost-effective solution with a low installation cost.

The connecting device can connect the circuit board in the contact hole by means of the electrically conductive contact layer without any loading, so that only by springing the plug sections onto the plating in the contact hole can a reliable and continuous electrical connection be achieved without the need for a complex loading connection.

In another example, a plug-in is provided with a bending plate that can be used to produce the plug-in described above. To this end, the plug-in can be bent along at least one bend line, so that by bending the plug-in the plug-in can be made as described above. For example, the plug-in can be provided as a thin, sheet-like (layered) material and the plug-in can be formed along its symmetry line. The plug-in can be perforated, in particular, the plug-in can provide a bending point at which the plug-in can be molded into plastic shapes. The plug-in can also provide a bending point along which all the plug-in elements can be mounted in a fixed position. For example, the plug-in can be mounted in the position defined above the plug-in and mounted in the middle of the plug-in.

In another example, a plug arrangement is provided in which the moulding tool is set up to compress the plug device locked to the circuit board, thereby unlocking the plug device locked to the circuit board. A locking by hook ensures a firm grip on the one hand, but is also loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosely loosly loosely loosely loosely loosely loosely loosely loosely loosely loos loosely loosely loosely loosely loos loosely loos

The semi-finished or finished plug device can be made individually from a single sheet of sheet metal by stamping and bending. Such an integral design of the plug element from a single sheet of sheet metal results in particularly low costs. Alternatively, a plug element can also be made from several components, for example to integrate additional functions.

The present invention provides a connector device with at least three independently elastically deformable connectors, which results in improved mechanical attachment in a contact hole and also provides improved conductivity between the connector and the circuit board. In particular, in a non-circular hole, a large number of independently elastically deformable connectors results in an improved demand for the connectors and thus in improved mechanical and electrical attachment or conductivity. An improvement in conductivity results in increased current transmission and lower transition resistance between the connector and the contact hole or circuit board, ensuring that at least one connector can be used in a contact area with less contact area than the one used in the connector.

Err1:Expecting ',' delimiter: line 1 column 398 (char 397)

The connector can be manually inserted directly into the corresponding contact holes of the circuit board by a human user without requiring a separate socket between the connector and the circuit board, as is the case with conventional high-current connectors. At the same time, despite the simple and intuitive insertion of the connector directly into the circuit board, a high vibration resistance can be ensured by providing a rigid mechanical safety by means of the single elements, which, when inserted, prevent the unintentional removal of the connector from the circuit board, for example caused by heating vibration forces, from becoming electrically unreliable.Compared with conventional high-current connectors, the invention is a radical change from conventional low-current systems such as the EP 1.069.651 A1 as it is impossible to simultaneously meet the requirements for parallel current resistance and vibration resistance with the design of the device, which results in space and cost savings and reduces or eliminates electrical losses or signal distortion due to a shortened transmission path or missing contact point.

In the transmission range, the connector may have high current material to provide sufficient electronic conductivity. The transmission range, or even the entire connector, may be made in particular of copper, aluminium, silver, gold or alloys such as brass or bronze. The ohmic resistance may be between 10 μΩ and 10 mΩ in the transmission range, preferably between 100 μΩ and 1 mΩ.

Detailed description of exemplary embodiments

The same or similar components in different figures are given the same reference numbers.

Fig. 1 shows an example of a plug device 100 for electrically connecting a conductor 300 (see Fig. 3) to a circuit board by directly inserting the plug device 100 into a contact hole of the circuit board. The plug device 100 has a mounting area 101 for attaching the plug device 300 to the connector device 100. The plug device 100 also has a transmission area for transmitting a current from the conductor 300 to the circuit board. The plug device 100 also has at least three connecting elements 102 that can be inserted into the connector jointly. Each of the single connecting elements 102 extends from a common base platform of the connector 103 to the connector 100. The connecting elements 102 are installed separately from the other connecting elements 102. If a connector 103 is inserted into the connector 102 and the base elements 102 are connected to each other, the connector 103 is provided with an elasticity that is independent of the connector 102 and the connector 102 is provided with a remote access.

The connector 100 is shown in Figure 1 in a side view, with two connectors 102 visible. For example, a third or a fourth connector 102 may be located behind it. Each of the connectors 102 extends from a base 103 of the connector 100. Each of the connectors 102 may be elastically deformed in the contact hole when built in. This causes each of the connectors 102 to attempt to deform back to its original position (undeformed position). This impulse to deform back to the original position creates a force that can be transferred to the inner surface of the contact conductor, resulting in a press force that causes the connector 100 to disconnect or disconnect from the connector.

Each of the connecting elements 102 may be at a certain angle from each other, i.e. not parallel to each other. This means that a distance of the connecting elements 102 from the base 103 in the direction of the connection 111 is increased. When the connecting device 100 is connected to the contact hole in the connection 111 direction, the connecting elements 102 are first bent and then unplugged after reaching a final connection position of the connecting device 100 so that the connecting elements 102 attempt to return to their original position. This creates the necessary pressure force to provide a press connection between the connecting device 100 and the circuit board.

Another way of achieving a connector connection may be to provide a central gap 106 between the connector elements 102. For example, the connector elements 102 may extend parallel to the base 103 with at least two of the at least three connector elements 102 being spaced by the gap 106. During the introduction of the connector elements 102 into the contact hole, they are compressed in the direction of the gap so that the connector elements 102 can be introduced into the contact hole due to the reduced diameter. After the connector device 100 is attached to the desired position, the connector elements 102 are reduced so that they attempt to bend back into their exit position. This dissolves the force that leads to the release of a compression plate with a 100 direction of the connector.

The position of the connecting device 100 relative to the circuit board can be defined, for example, by means of a contact area 107 The contact area can be, for example, a raised area that extends across the input direction 111 or parallel to a surface of the circuit board This increases the diameter of the area of the connecting device 100 where the input direction 107 is defined so that this area no longer passes through the contact hole with the input direction 107 and thus a further movement in the input direction 111 can be prevented.

The contact area 107 can be defined, for example, at the base body 103 or at all or even only one of the connecting elements 102 As shown in Figure 1, a contact area 107 can be defined at the two connecting elements 102. This means that the connecting device 100 can finally be inserted into the contact hole in the connecting direction 111 until the contact area 107 touches the surface of the circuit board.

The section of the plug element 102 which is in the contact hole when the plug elements 102 are inserted into the contact hole is defined as the plug section 105. The plug section 105 may, for example, be coated with a conductive layer or be made entirely of a conductive material, so that in addition to a mechanical press connection, electrical conductivity can also be provided via the contact to the circuit board. The transmission range can thus be defined on the one hand in the plug hole 105. On the other hand, the transmission range can also be provided at other contact areas of the plug device 100 with the circuit board. For example, at the connecting points 107 a transmission range can be provided for the transmission of a current to the circuit board.

As shown in Figure 1, the insertion section 105 may have a convex surface shape, for example, the convex surface shape is provided in particular on the side of an insertion element 102 which, when plugged in, is oriented to an inner surface of the contact hole. The convex surface of the insertion section 105 increases the surface compression, i.e. the force per unit area, between an insertion element 102 and the inner surface of the contact hole. This allows a higher pressure force to be achieved, thus increasing the press connection and thus also the friction of the insertion elements 102 with the inner surface of the contact hole.

The area of the connecting device 100 which, when the connecting device 100 is in the hole, protrudes out of the contact hole in the direction 111 of the entry may be designated as the terminal section 112 of the connecting elements 102. In this terminal section 112 there are also the respective free ends 104 of the connecting elements 102. The free ends 104 may be rounded so that there is a reduced risk of contact dispersion when the connecting elements 102 are inserted into the hole. In the terminal section 112 at least one of the connecting elements 102 is connected by an extension surface 108, which can act as a back cutting, if the connecting element 102 is sufficiently inserted into the contact hole. The extension surface 108 may be connected by a single interlocking of the connecting elements 102 with a single interlocking surface 108 in a certain direction, as the connecting elements 102 and 108 may be connected by a single interlocking surface 102 in a certain direction.

A solution to the dispersion may be provided, for example, by compressing the connecting elements 102 in the terminal section 112 and simultaneously moving the connecting device 100 in the direction of the connecting element 111.

In addition, the extension 108 may have a first surface 109 with an inclined plane or inclined plane, so that only a movement of the connecting device 100 in the direction of insertion 111 is necessary to remove the dispersion. In other words, the inclined plane 109 of the first surface 109 forms a cone shape of the extension 108, with the cone tip oriented towards the contact hole in the insertion state, and extends from the cone tip the first surface or inclined plane in the direction of insertion 111 outwards, so that in the direction of insertion 111 the thickness of the insertion element 110 increases with the first surface 108 being divided. In other words, the angle between the first surface 109 and the first surface 109 is 90°, which means that the surface 110 can be formed by a curve of 90°, which is parallel to the first surface 109 and the first surface 109 means that the surface 111 is divided into a circle of 102 points.

The inclined plane of the diagonals 109 causes, when the inserts 102 are pulled out against the direction of insertion 111, a force from the impact of the first surface 109 on the surface of the circuit board to be generated and transmitted inward, i.e. to the centre of the contact hole or towards the column 106, so that the inserts 102 automatically deform elastically by pulling out towards the column 106. This reduces the cross-section of all inserts 102 in such a way that the inserts 108 including their rear intersections fit through the contact hole, so that the inserts 100 can be pulled out. By means of the conical first surface, it can be ensured that the inserts 102 are pulled out of the contact hole with the greatest force required to remove the inserts.

The mounting area 101 to which the conductor 300 (see Fig. 3) can be attached, for example by means of clamping or soldering, may be located on the opposite side of the connecting device 100 in relation to the connecting elements 102. As shown in Fig. 1, the mounting area 101 may have two tubes 110, which may be plastically deformed and placed around the conductor 300, so that a clamping force can be transmitted to the conductor 300 and thus be held by a clamping connection. The tubes 110 or other elements of the mounting area 101 may have electrical conductive properties, so that a current can be directed from the conductor 300 over the mounting area to the transmission area 101.

For example, the length of a plug element 102 may be 8 to 12 mm (millimetres); the diameter of a plug element 102 may be 0.5 to 1 mm; the gap 106 between two plug elements 102 may be between 0.5 mm and 0.8 mm; the plug section 105 may be 2.5 mm to 3 mm long; or the plug section 105 may be adjusted to a thickness of the circuit board.

Furthermore, Figure 2 shows the column 106 separating the first and second groups of connecting elements 102 and the connecting elements 102 which can be compressed in pairs in the direction of column 106 and elastically deformed to be inserted into the contact hole.

Figure 3 shows the section B-B from Figure 1, showing a view of the 100th anchorage area of the 100th connector. For example, the 101st anchorage area shows the two 110-pin bars which are attached to the conductor 300. The 110-pin bars can be plastically deformable and can be bent around the conductor so that a clamping force can be generated and the 300th conductor can be attached to the 100th connector by a clamping connection.

Fig. 4 shows an example of a plug-in half-pipe 400 of the plug-in device 100. The plug-in half-pipe 400 may, for example, consist of two halves separated by the bending line 401. The bending line 401 may represent a target bending line which may, for example, provide a preferred bending edge by perforation or material weakening. In practice, for example, the conductor may first be inserted in the attachment area 101. Then each half of the plug-in half-pipe 400 may be bent along the bending line so that both halves of the plug-in half-pipe 400 are adjacent to each other. Subsequently, for the plastic fixation of the welding fixture 300, the 110 connectors of the welding pipe 400 may be produced by means of a mold so that the 110 300 are inserted.In the folded state of both halves of the connector 400, for example, the four insert elements 102 shown may be in pairs, so that a cross-section is produced, as shown in Fig. 2. The connector 400 may already have all the other features and characteristics of the connector device 100. Thus, the connector 400 may already have the base 103 and the contact area 107. Furthermore, the connector 400 may already have the four insert elements 102, including their insert expansion sections 105 and end sections 112.and the rounded free ends 104.

Figure 5 shows a plug-in half-piece 500 of a foldable sheet metal material according to another exemplary embodiment of the present invention.

Folding the plug 500 along an axis of symmetry 510 gives a plug device similar to that shown in Figure 6.

Figure 6 shows a connecting device 600 for the electrical connection of a conductor capable of being engaged by means of a latch 110 to a circuit board 602 shown in the cross section.

The connecting device 600 has two pairs of connectors 502, 504 (see Fig. 5). The four connectors 502, 502, 504, 504 are inserted together into a single contact hole of the circuit board 602 and compressed by springing towards a centre axis 620. When the connecting devices 105 are connected to an electrically conductive contact 604 at the contact hole in the circuit board 602, the connecting devices 105 push outwards, thus establishing an electrically conductive connection between the connecting devices 105 and the electrically conductive contact 604.

In particular, one of the 504 inserts itself has the underlying locking mechanism, which is based on the fact that when the 600 is passed through the contact hole to attach the 600 to the 602 circuit board, the 600 is locked by a spring-loaded counter-hook to the 602 circuit board, by pressing the 504 inserts together again and then removing the 600 from the contact hole of the 602 circuit board, creating a reversible and therefore any number of times applicable locking logic.

A first of the 502 connectors consists of a convex 105 connector that is located inside the contact hole and in direct contact with the electrically conductive contact 604 when the 502 connectors are inserted into the 504 connector. A second of the 504 connectors has a 105 connector that extends from the base 103 as does the 105 connector of the 502 first connector. The 105 connector of the 504 second connector is also located inside the contact hole when the 502 connectors are inserted into the 504 first connector. The 504 second connector also has an arc section 506 that extends from the 105 connector through the contact hole to the 1052 cable through the first connector.When the plugs 504 are pressed together laterally by introducing them into the contact hole, the column 1000 also decreases in size. After the plugs 600 have been inserted into the circuit board 602 the plugs 504 increase again in size until the suspension system is in a powerless state.which is formed at a point in the essentially pear-shaped structure from the input elements 502, 504 where the coherent structure from the input elements 502, 504 is interrupted by the gap 1000.

A freely movable and rounded end area 506d of the arc section 506 is compressible by spring when the connector is inserted into the circuit board 602 and is passable through the contact hole and, after being inserted through the contact hole, floats back outwards, locking the connector 600 automatically to the circuit board 602 by means of the end area 506d. The rounded end area 506d of the arc section 506 forms a concave area adjacent to the convex input section 105 of the first input element 502.

The arc section 506 contains two opposite and parallel longitudinal sections 506a, 506c, connected by an arc 506b, which is spaced by the longitudinal sections 506a, 506c, opposite the insertion sections 105 of the first and second insertion elements 502, 504.

As shown in Figures 5 and 6, there are two pairs of connectors 502, 504 in total, which are arranged in such a way relative to each other in the folded state of the connector 500 shown in Figure 6 that, after the connector 600 is inserted into the circuit board 602, the locking mechanism forms two hooks at two opposite sides of the contact hole to prevent the connector 600 from being removed from the circuit board 602 in a symmetrical manner.

The second and fourth inserts 504, 504 are axisymmetrically opposite each other. The corresponding axis of symmetry is perpendicular to the paper plane and is located in a centre of gravity of gap 106 as shown in Fig. 9. This axis of symmetry corresponds to the centre axis 620 shown in Fig. 6.

The second and fourth connecting elements 504, 504 are in contact with each other and thus contact each other; the second and fourth connecting elements 504, 504 are in contact with each other in an upper area as shown in Figure 6; the first and fourth connecting elements 502, 504 are in contact with each other in a lower area as shown in Figure 6; the second and third connecting elements 502, 504 are in contact with each other in a lower area as shown in Figure 6.

As shown in Fig. 6, a folding of the connector 500 allows two movable legs to be obtained which can move outwards when the connector 600 is inserted into a contact hole of the circuit board 602 (compare position 1). The screw hook of the arc section 504 has springing properties and, after correctly fitted, rests on the circuit board 602 (compare position 2).

Figure 7 shows a cross-sectional view of the connecting device 600 along an A-A line. Figure 7 shows that in a rear area of the connecting device 600 in which a cylindrical conductor or similar can be accommodated, the two halves of the fold remain at a certain distance from each other.

Figure 8 shows a side view of the connector 600. All the connectors 502, 504 are made out of a flat plate, in particular, they are stamped out. As shown in Figure 8, the connectors 502, 504 of the connector 600 therefore have a constant thickness in a direction perpendicular to the direction of the spring of the arc section 506.

Figure 9 shows a different cross-sectional view of the connector 600 along a line B-B. Figure 9 shows the relative position of the connecting elements 502, 502, 504, 505 at the point B-B.

Figure 10 an enlarged representation of a part of a plug-in device similar in design to that shown in Figure 6 and having some additional features.

Figure 10 shows a schematic of a moulding tool 1004 (with two interchangeable clamping buckets) which is arranged to operate the plug device locked on the circuit board 602 in such a way that the plug device locked on the circuit board 602 is unlockable. More specifically, the moulding tool is arranged to compress the plug device locked on the circuit board 602 so that the plug device locked on the circuit board 602 is unlocked. The moulding tool 1004 is shown in Figure 10 in the form of two clamping buckets which can be moved in parallel to each other. This allows the single elements 504 to be mounted in such a way that the invention can be mounted in a compact form, which is very selective, as long as the two elements 506 and 104 are designed in a way that is self-similar.

Between the arc section 506 and the insertion section 105 of the insertion element 504 a breakpoint 1002 is formed, which leads to a break between the arc section 506 and the insertion section 105 if a designated breakpoint load is exceeded. The breakpoint 1002 is formed in the example shown as a material weakening, i.e. as a thin point, but many other configurations can also be placed on or elsewhere. In particular, a breakpoint 1002 may be contained in a transition from the electrical contact zone (insertion section 105) to the locking hook (arc section 506) when a designated breakpoint load is exceeded. This allows the contact to be resolved, for example, in an emergency, but virtually, but the connection is not resolved.
