Description

The invention relates to a contacting device with the features specified in claim 1. The invention also relates to a component having the features specified in claim 9. The invention also relates to a method having the features specified in claim 10.

According to the state of the art, electrical or electronic components for components or electrical or electronic subcomponents, in particular for motor vehicles, are soldered to conductor tracks on a printed circuit board and / or screwed to other current-carrying components - such as a housing of the component or the subcomponent (component housing) and electrically contacted. For this purpose, the respective printed circuit board is equipped with “catalog goods”, that is to say with commercially available components that are ready-made for use as intended, for example resistors, capacitors, coils, etc. The circuit board in turn is arranged in the component housing and mechanically connected to it, for example the circuit board and the component housing are screwed together. Depending on the requirements, electrically conductive screw connections on the metallic component housing can be selected, for example in order to connect the printed circuit board and the component housing to one another in an electrically conductive manner for the purpose of earthing the component. Furthermore, electrically insulating screw connections can be selected in order to electrically isolate the printed circuit board and the component housing from one another.

In particular, for the development of a motor vehicle and / or for testing a motor vehicle, it is necessary to be able to reconfigure the subcomponent particularly quickly and with little effort in terms of the components, for example in order to be able to perform several tests particularly efficiently with regard to a particularly advantageous EMC (electromagnetic compatibility) of the subcomponent and, consequently, of the entire subcomponent to be able to carry out motor vehicle to be developed or tested. Furthermore, there is a need for the simple and quick reconfiguration of the component or the subcomponent even in a finished motor vehicle, for example in order to be able to adapt a system performance of the component to different variants of the motor vehicle particularly efficiently and thus economically. However, the soldered connection between the components and the printed circuit board stands in the way of this requirement.

Furthermore, the printed circuit board used in such a conventional subcomponent requires its own installation space, as a result of which the subcomponent is designed to be only slightly efficient in terms of installation space. In addition, the printed circuit board and the component housing are to be mechanically fixed to one another by means of the screw connection already mentioned or by means of some other connection technology, so that the component cannot be moved loosely in the component housing in an undesired manner. This conventional subcomponent is therefore particularly complex to manufacture. Furthermore, integrating the subcomponent into an electrical and / or electronic network of the motor vehicle is also particularly complex, since at least one further connecting element is required in order to make electrical contact between the printed circuit board and the component. For example, a connection is required within the component housing that electrically connects the printed circuit board and the plug contacts on the outside of the housing to one another.

Since different component configurations of the conventional component or the conventional subcomponent are produced by populating the circuit board and the associated removal and (re) installation, the testing and / or development of the motor vehicle is particularly complex.

It is the object of the invention to make the production and / or reconfiguration of an electrical or electronic component with at least one electrical and / or electronic component particularly simple and inexpensive.

From the prior art, electrical or electronic components or components are known which can be mechanically and / or electrically contacted with a printed circuit board or printed circuit board by means of at least two spring elements. For this purpose, the at least two spring elements are each designed as a respective connection element of an electrical and / or electronic component. the DE 20 2014 011 393 U1 discloses a component connector assembly for pluggably connecting a component to a circuit board. the DE 10 2017 211 336 A1 discloses a power module with a semiconductor carrier element to be electrically contacted on the top and / or bottom.

In the conventional component plug-in connection arrangement or in the conventional power module, however, the corresponding electrical and / or electronic components are designed very specifically for the respective application. This means that the corresponding electrical and / or electronic components are not very flexible or not very versatile.

It is the object of the invention to produce and / or reconfigure an electrical or electronic component with at least one to train electrical and / or electronic component particularly simple and inexpensive.

According to the invention, this object is achieved by a contacting device having the features specified in claim 1. Furthermore, this object is achieved by a component having such a contacting device with the feature specified in claim 9. In addition, the object is achieved by a method for equipping an electrical and / or electronic assembly, which is designed according to patent claim 10. Features, advantages and advantageous configurations of the contacting device according to the invention are to be regarded as features, advantages and advantageous configurations of the component according to the invention or the method according to the invention, and vice versa. Features, advantages and advantageous configurations of the component according to the invention are to be regarded as features, advantages and advantageous configurations of the method according to the invention and vice versa. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

According to the invention, a contacting device for modifying an electrical or electronic component is proposed. The component can be used, for example, in a motor vehicle. The electrical or electronic component is in particular a commercially available electrical or electronic component. This means that the commercially available component is designed as it is, that is to say before it is modified by means of the contacting device, to be connected to an electrical circuit board or circuit board as intended. The component has a component housing, on the housing surface of which at least two electrical connection elements, for example pins and / or solderable connection surfaces, are arranged, by means of which the commercially available component can be directly contacted, for example directly soldered, to the printed circuit board. In other words, the component thus comprises the at least two electrical connection elements, which can be designed as the pins and / or the solderable connection surfaces. The pins are typically designed for so-called through-hole mounting of the component on the printed circuit board. The pins are generally cylindrical, in particular prismatic, projections which, in particular perpendicularly, can protrude from the surface of the housing. In contrast, the solderable connection surfaces are provided for what is known as surface mounting of the component on the printed circuit board and, in particular, are free of projections extending away from the housing or the housing surface or free of pins. This is particularly the case when the component is designed as an SMD component (SMD: surface-mounted device). In any case, the electrical connection elements can be arranged on a common surface part. For example, the pins can protrude from the common surface part. Analogously, the solderable connection surfaces can lie in the common surface part.

The component housing encloses an inner workings of the component and has at least three interconnected housing surface parts which together form the component housing. The component housing accordingly has a shape following a general cylinder. Common shapes or forms of such a commercially available component are (not conclusively and only mentioned as an example) a straight circular cylinder, a cuboid, etc.

As already explained at the outset, such conventional and commercially available electrical or electronic components can only be used with little flexibility, since their replacement, when the corresponding component is used in an electrical and / or electronic component, is particularly complex. This is because a soldered connection between the component and the printed circuit board must be undone for this purpose, as well as any further mechanical connection that may be present between the component and the printed circuit board and / or a housing of the component or a component housing. Accordingly, the contacting device according to the invention has two contacting bodies, which are electrically insulated from one another and each have a spring element. This contacting device can be attached to the component or to its component housing, the spring elements representing a respective holding element via which the component, if it is equipped with the contacting device, is held or fixed in a corresponding housing, for example the component housing.

In order to make a production and / or reconfiguration of the electrical or electronic component with at least one electrical and / or electronic component particularly simple and inexpensive, it is provided according to the invention that the respective contacting body comprises a fastening element, by means of which the component housing and the respective contacting body are attached to one another can be fastened, wherein the respective spring element and a correspondingly assigned connection element can be electrically contacted with one another. In other words, when modifying the commercially available component, the respective connection element and the corresponding contact-making body are fastened with the respective contacting body on the component housing electrically contacted with one another, for example by bringing the respective connection element and the respective contacting body into direct mechanical contact with one another. In order to integrate the commercially available component into the electrical or electronic component so that the conventional component provides at least one electrical function during operation of the component, separate connection, in particular soldering, can be omitted, because the component is in the component via the contacting device integrable. Accordingly, when removing the component from the component, there is no need to desolder the component or to break a soldered connection between the component and any printed circuit board of the component.

So if there is a need to reconfigure the component, which in particular has more than one electrical or electronic component, for example as part of a development of the component and / or as part of a test of the component, for example with regard to an electromagnetic compatibility (EMC) of the component, this can take place particularly easily and / or with little effort due to the contacting device.

In a further embodiment of the contacting device, the spring elements can be arranged on opposite housing surface parts of the component housing in such a way that the spring elements protrude from the corresponding housing surface part in the assembled state of the contacting device. Furthermore, the spring elements are designed to mechanically fix the component between two connection rails of the electrical or electronic component and to make electrical contact between the component and the connection rails. For this purpose, the spring elements can be adjusted or tensioned from an at least substantially relaxed state to an at least partially tensioned state, with the contacting device being supported between and on the two connecting rails in this tensioned state of the spring elements by the spring force of the tensioned spring elements acting on the connecting rails works. Because of the mechanical holding or under the mechanical holding, the component can be or is connected to the connecting rails in an electrically conductive manner via the contacting device. This means that the contacting device has a double functionality, namely - firstly - provides an electrical contacting option for the component and - secondly - provides a mechanical fastening option for the component.

In order to ensure a particularly firm and reliable seat of the component in the contacting device or to ensure a particularly firm and reliable seat of the contacting device on the component, a further advantageous embodiment of the contacting device provides that the respective contacting body is designed to be at least to come to direct contact with three different housing surface parts of the component housing. In other words, the respective contacting body directly adjoins at least three of the housing surface parts of the component housing when the contacting device and the component are connected to one another or fastened to one another as intended.

In order to make the component, which can be modified by means of the contacting device, particularly versatile or flexible, it is provided in a further embodiment of the contacting device that the respective contacting body has a first section, which is provided on a first housing surface part of the component housing correspondingly assigned to the connection elements and the contacting body to be electrically connected to one another. Furthermore, the contact-making body has a further section which is different from the first section, the sections being connected to one another in an electrically conductive or conductive manner, in particular in a materially bonded manner. The further section has the spring element of the contacting body and comes to rest on a further housing surface part of the component housing that is different from the first housing surface part when the electrical or electronic component has been modified by means of the contacting device. In this way, an electrical contacting point or connection point of the component modified by means of the contacting device can be laid on a housing surface part which is free of the connection elements in the unmodified component. In this way, it is possible to integrate the component into the component in a particularly space-efficient manner due to the contacting device.

In a further advantageous embodiment of the contacting device, it is provided that the fastening element has a form-fitting element which corresponds to the component housing, so that a form-fit connection can be mediated between the component housing and the contacting device. This means that when the component is modified by means of the contacting device, a form fit is closed between the component housing and the contacting device. This is how the component is kept particularly safe and reliable in the contacting device. Viewed the other way around, the contact-making device is held or can be held particularly securely on the component housing by the form fit.

The contacting device and the component housing can be fastened or fastened to one another even more securely and / or reliably if - as in accordance with a further embodiment - the fastening element has a frictional connection element which corresponds to the component housing, so that a frictional connection can be mediated between the component housing and the contacting device. It is conceivable that the form fit described above and the force fit complement one another, that is to say are present at the same time in the component modified by means of the contacting device.

Likewise in the sense of a particularly secure and / or particularly reliable, in particular mechanical connection between the contacting device and the component housing, it is when - according to a further embodiment of the contacting device - the fastening element has a material connection element which corresponds to a predetermined material connection element of the component housing, so that between a material bond can be imparted to the component housing and the contacting device. The fastening element preferably has an adhesive so that the contacting device and a predetermined adhesive surface, which is formed in particular by the predetermined adhesive element of the component housing, for example by a specific housing surface part, can be glued directly to one another.

The form fit, the force fit and the material fit can be present together with one another or individually or at least two of these connection connections.

It has also proven to be advantageous if the respective contacting body has a material connection section via which the contacting body and the correspondingly assigned electrical connection element can be connected directly to one another in a materially and electrically conductive manner. It is preferably provided that the material connection section and the material connection element of the fastening element are elements and / or sections of the corresponding contacting body that are separate from one another. Alternatively, it can be provided that the material connection section is the material connection element of the fastening element.

In any case, a particularly reliable electrical contact between the electrical connection element and the contacting body is ensured if the electrical connection element, for example the corresponding pin, and the corresponding contacting body are materially connected to one another, for example soldered to one another. Furthermore, it is conceivable that the corresponding electrical connection element and the corresponding contact-making body are welded to one another or glued to one another by means of an electrically conductive adhesive. In this way, not only is a particularly reliable mechanical fastening of the contacting body to the component housing and the corresponding connection element ensured, but an electrical connection or an electrically conductive or conductive connection between the corresponding electrical connection element and the corresponding contacting body is also ensured. As a result, the component modified by means of the contacting device is particularly reliable since the electrical and / or mechanical contact between the component and the contacting device is ensured even if the component modified by the contacting device is subject to (recurring) vibrations. Such vibrations occur, for example, during driving operation or due to driving operation of the motor vehicle. If the component modified by means of the contacting device and / or a component that has a large number of modified components is used in the motor vehicle, the component and / or the component are / is particularly reliable, so that functional reliability of the motor vehicle is guaranteed.

The invention also relates to a component which has at least one electronic or electrical component. This component comprises a component housing, on the housing surface of which at least two electrical connection elements are arranged. By means of the electrical connection elements, the component can be contacted directly, for example soldered, to a printed circuit board or printed circuit board.

In order to ensure a particularly simple and / or low-cost reconfiguration of the component, which is an electrical and / or electronic component, it is provided according to the invention that the electrical and / or electronic component is modified by means of a contacting device. This means that the electrical or electronic component that is used in the electrical or electronic component, for example, in this is installed, is connected to the contacting device, in particular electrically and mechanically.

Finally, the invention relates to a method for equipping an electrical and / or electronic assembly with at least one electrical or electronic component, the method having at least the following steps (not necessarily in the order described herein): Provisioning takes place in one step of the method an assembly housing having at least two connecting rails. In a further step of the method, at least one component is provided which has at least one electrical and / or electronic component. According to a further step of the method, the at least one component is contacted to the connecting rails of the assembly housing.

In order to make a production and / or reconfiguration of the component or the assembly with the at least one component particularly simple and / or inexpensive, the invention provides that an electrical and / or electronic component of the component can be connected to the component via a contacting device connected to the component Connecting rails is held and electrically contacted.

A reconfiguration of the assembly, which has a large number of electronic and / or electrical components or components, is then particularly simple, since the respective component or the respective component can be removed from the assembly as intended by merely making the mechanical connection between the connecting rails and the component is lifted. For this purpose, only at least one of the spring elements needs to be tensioned in order to cancel the force fit or form fit between the connecting rails and the component. Since a soldered connection or some other material connection between the connecting bars and the component is not intended, logically there is no need to break or melt or otherwise destroy such a material connection or the soldered connection.

In particular, it is provided that the at least two connecting rails are directly opposite one another and the spring elements are arranged on housing surface parts of the component housing that are opposite to one another or point away from one another and each protrude therefrom.

The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination, but also in other combinations or on their own.

The following is a contacting device 1 , a component 2 and a method for equipping an electrical and / or electronic assembly 3 described together.

In 1 is a schematic view of a commercially available electrical or electronic component 4th shown. The commercially available component can, for example, be a Coil, a capacitor, in particular a film capacitor, a transistor, a resistor, etc. act. The component 4th has a component housing 5 on, the at least three housing surface parts 6th having. The housing surface parts 6th together form the component housing 5 . The housing surface parts are for this purpose 6th connected with each other. The component housing 5 or the component 4th is designed according to a general cylinder, in particular prismatic or circular cylindrical. Is the component 4th or the component housing 5 , as in 1 shown, prismatic, in particular cuboid-shaped, has the component housing 5 six housing surface parts 6th on, whereas the component 4th or the component housing 5 three housing surface parts 6th if it is cylindrical or circular-cylindrical (see 4th ).

On a housing surface of the component housing 5 , for example on one of the housing surface parts 6th , are two electrical connection elements 7th formed, which in the present example are each represented as a pin. By means of the connection elements 7th or by means of the pins is the commercially available component 4th directly and easily with a printed circuit board or printed circuit board (not shown) electrically and mechanically connectable, for example solderable. To this extent, it is the electrical or electronic component 4th a commercially available component which, as far as it has been described up to this point, is ready for use as intended or for use as intended. In other words, a manufacturer of a conventional assembly purchases this commercially available component 4th , especially in large numbers, in order to connect this to the printed circuit board or printed circuit board. In other words, it is the commercially available component 4th about "catalog goods".

So does the manufacturer of the conventional assembly have the component 4th soldered to the printed circuit board or printed circuit board, this soldered connection is to be broken or melted if the conventional assembly is to be reconfigured, with at least one of the commercially available components, for example, in the course of this reconfiguration 4th by another commercially available component 4th to be replaced. However, this is particularly complex.

In 2 is a schematic view of the commercially available component 4th shown by means of the contacting device 1 has been modified. The commercially available electrical or electronic component 4th and the contacting device 1 together form the component 2 . In other words, the component comprises 2 at least one commercially available component 4th and the contacting device 1 . The contacting device 1 has two contacting bodies in the present example 8th on, the respective contacting body 8th with the component housing 5 , at least with a portion of the same, corresponds. With the two contacting bodies 8th it can be, for example, identical parts, that is, the two contacting bodies 8th can correspond to one another or be of the same design. It is in 2 to see that the two contacting bodies 8th on opposite housing surface parts 6th of the component 4th are arranged and the component housing 5 at least partially embrace. In addition, the respective contacting body 8th a spring element 9 on, which is designed as a bow spring element in the present example. Here are the respective contacting bodies 8th and the respective spring element 9 connected to one another in a materially bonded manner, in particular formed in one piece with one another. This means that the respective spring element 9 part of the respective contacting body 8th can be.

The respective contacting body 8th furthermore has a respective fastening element 10 on, by means of which the component housing 5 and the respective contacting body 8th are attachable to each other. The respective contacting body 8th and the respective fastening element 10 can be cohesively connected to one another, in particular be formed in one piece with one another. If this is the case, it means that the respective spring element 9 and the respective fastening element 10 can be cohesively connected to one another, for example via a material of the contacting body 8th . Furthermore, in this case it can be provided that the respective contacting body 8th , the respective spring element 9 and the respective fastening element 10 are formed integrally with one another or are at least materially connected to one another.

With the component 2 as it is in 2 is shown, has the respective fastening element 10 a respective through opening 11th on which the contacting body 8th on one (first) leg 12th completely penetrates. A positional location of the respective passage opening 11th and a respective positional position of the respective connection element 7th correspond to one another in such a way that - firstly - the respective contacting body 8th as intended on the component housing 5 can be placed and - secondly - a longitudinal center axis of the respective connection element 7th and a longitudinal center axis of the respective through opening 11th to coincide. That means that with the component 2 , that is, if the component 4th and the contacting device 1 are assembled, the respective connection element 7th through the respective passage opening 11th extends through. It can be provided here that an outer circumferential surface of the respective connection element 7th and an inner peripheral surface of the respective through hole 11th are in direct or immediate contact with one another or are in direct contact with one another, so that between the respective connection element 7th and the respective contacting body 8th electrical contact is established. Since it is provided that the contacting device 1 , that is, the respective contacting body 8th and the respective spring element 9 as well as the respective first leg 12th , are formed from an electrically conductive or conductive material, for example a metal, consists in the component 2 an electrically conductive or conductive connection between the respective connection element 7th and the respective spring element 9 .

In this way, the contacting device 1 for the commercially available component 4th on the one hand, a mechanical fastening option is available. Because that with the contacting device 1 equipped commercial component 4th or the component 2 is particularly simple and / or requires little effort between two connecting rails 13th (shown for the first time in 9 ) and between these connecting rails 13th can be held or mechanically fixed. On the other hand is through the contacting device 1 an electrical connection option for the contacting device 1 equipped component 4th or for the component 2 provided as the respective connection element 7th and the respective spring element 9 are electrically connected to each other.

It is also to be understood that the two contacting bodies 8th electrically isolated from one another, for example, are arranged without contact with one another.

To ensure a particularly reliable fit of the respective contacting body 8th on the component housing 5 The respective contacting body includes even further support 8th another (second) leg 14th on. The thigh 12th , 14th are over another (third) leg 15th spaced apart, the legs 12th , 14th can be arranged parallel to one another, as shown in 2 is shown. Furthermore, in 2 shown that the first leg 12th and the third leg 15th as well as the second leg 14th and the third leg 15th each can enclose an angle of 90 ° with one another. This applies at least when the respective contacting body 8th on the component housing 5 is properly placed. Because it can be provided that the respective contacting body 8th if this and the commercially available component 4th are not yet attached to each other, is relaxed, with the thighs 12th , 14th are not arranged parallel to each other, but point towards each other. In other words, it can be provided that the first leg 12th , the second leg 14th and / or the third leg 15th are / is in each case designed as a spring element itself, the leg (s) 12th , 14th , 15th or the respective spring element are / is to be relaxed in order to properly mount the respective contacting body 8th to the component housing 5 to enable. It then acts on the component 2 a spring force of the first leg 12th , of the second leg 14th and / or the third leg 15th on the component housing 5 , so that between the respective contacting body 8th and the component housing 5 a frictional connection is generated. In this respect, the respective contacting body can 8th on the component housing 5 be stretched.

So there, as in 2 is shown the thighs 12th , 14th , 15th on different parts of the housing surface 6th of the component housing 5 are applied, is the respective contacting body 8th particularly secure on the component housing 5 held.

In the present example is through the respective first leg 12th a material connection section 16 of the respective contacting body 8th educated. About the material connection section 16 are the respective contacting body 8th and the correspondingly assigned one of the electrical connection elements 7th or the pins are directly connected to one another in a materially and electrically conductive or conductive manner. For electrical and mechanical contacting of the material connection section 16 with the corresponding connection element 7th In the present case, there is a material connection element 17th for use, which can be a solder, for example tin solder, or an electrically conductive adhesive. The electrically conductive material connection element 17th is both with the corresponding connection element 7th as well as with the corresponding material connection section 16 each materially connected. In this respect, the component prevails 2 between the corresponding electrical connection element 7th and the corresponding contacting body 8th a particularly reliable mechanical and electrical connection.

3 shows one of the contacting bodies in a schematic plan view 8th , the one on the commercially available component 4th is appropriate. Since - as already mentioned above - the contacting bodies 8th can be formed identically, will be used below for both contacting bodies 8th only one of the contacting bodies 8th described.

The commercially available component 4th is in 3 to be viewed as if the connection element was cracking 7th from the plane of the drawing. Accordingly, there is a plan view of the first leg 12th of the contacting body 8th . It can be seen that the first leg 12th a first section 18th of the contacting body 8th forms on which the through opening 11th of the fastener 10 is arranged. The first section is accordingly 18th designed for the correspondingly assigned one of the connection elements 7th and the contacting body 8th to connect electrically to each other. Furthermore, the 3 with the 2 clearly that the respective spring element 9 from a further or second section 19th of the corresponding contacting body 8th protrudes, this second section 19th through the third leg 15th of the contacting body 8th is formed. As the sections 18th , 19th or the thighs 12th , 15th on different parts of the housing surface 6th of the component 4th come to the system is an electrical connection point of the component 2 , that is, the one with the contacting device 1 equipped component 4th , relocated across from that of the contacting device 1 free commercial component 4th . This means that the contacting device 1 can be used for this, the electrical connection point of the commercially available component 4th , usually through the corresponding connection elements 7th is set or defined, as required, for example on another housing surface part 6th , relocate.

It is also in 3 the material connection element 17th Shown hatched, the corresponding connection element 7th surrounds ring-shaped and with the connection element 7th as well as with the first leg 12th or with the material connection section 16 of the contacting body 8th is firmly connected. Are - as preferred - the electrical connection element 7th and the bond section 16 of the contacting body 8th soldered to one another, it is provided that the solder at least partially into the through-opening 11th flows into it. This is made possible because it is provided that a diameter of the respective electrical connection element 7th is smaller than an inner diameter of the through opening 11th . This results in between the outer circumferential surface of the respective electrical connection element 7th and the inner peripheral surface of the through hole 11th a material-free space or air space formed, for example, in the shape of a ring, which occurs when the connection element is soldered 7th with the material connection section 16 can be filled with the solder.

4th shows in a schematic plan view that by means of the contacting device 1 modified component 4th , which has an at least partially round cross-section. Since the contacting body 8th and the component housing 5 correspond to one another, is in this case the contacting body 8th also provided with an at least partially round cross-section. The component 4th can for example be a part of the housing 5a have, which is designed according to a right circular cylinder. Alternatively, the component 4th a housing part 5b have, which is designed according to a cuboid. It is also conceivable that the component 4th or its component housing 5 is a mixed form, that is, for example, the cuboid housing part 5b which is closed on at least one side or side surface by a straight semicircular cylinder.

To put on or put on the contacting body 8th on the component housing 5 To simplify even further, it can be provided that the through opening 11th in the direction towards an edge of the first leg 12th is open. In other words, the leg can 12th have a material recess that forms the through opening 11th along one edge of the leg 12th opens. In this way there is a bending of the corresponding contact-making body 8th and / or the corresponding electrical connection element 7th or pins while the contacting body is being placed or plugged on 8th on the component housing 5 effectively prevented.

It is provided here that a measure 20th , for example a width, a length or a depth, of the component 4th is greater than a corresponding dimension 21 of the contacting body 8th , taking the dimensions 20th , 21 are parallel to each other.

In a further embodiment of the contacting device 1 this has a form-fitting element 22nd on. This is in 6th shown, which is a schematic side view of the contacting body 8th in a further embodiment of the contacting device 1 represents. The form-fit element 22nd can be part of the fastener 10 be. In other words, the fastening element 10 the form-fit element 22nd exhibit. The form-fit element 22nd corresponds to the component housing 5 so that between the component housing 5 and the contacting device 1 a form fit can be conveyed. In particular, is between the component housing 5 and the contacting device 1 a multiplicity of form-fit connections can be conveyed, that is to say in the case of the component 2 mediated, since the interaction of the respective pin or electrical connection element 7th with the through hole 11th represents a first form fit. As an alternative or in addition to the first form fit, the form fit element is used 22nd and the corresponding Component housing 5 another form fit can be formed and on the component 2 educated.

In the present example, the form-fit element is 22nd through another (fourth) leg 23 of the corresponding contacting body 8th educated. This is where the third leg border 15th and the fourth leg 23 directly to one another, in particular on both sides of the third leg 15th such a fourth leg 23 or such a form-fit element 22nd is arranged.

This creates the force or frictional connection between the corresponding contacting body 8th and the component housing 5 negotiable. In other words, is with the component 2 between the component housing 5 and the respective contacting body 8th - As an alternative or in addition to the form fit described above - the force fit or friction fit is generated, that is, closed. Analogous to the first leg 12th and to the second leg 14th can the fourth leg 23 or the form-fit element 22nd be designed as a spring element. In this way, the frictional connection or frictional connection is between the contacting body 8th and the component housing 5 even further strengthened. That means that the respective leg 12th , 14th , 15th , 23 one frictional connection element each 24 of the contacting body 8th or the contacting device 1 forms. Furthermore, it can be provided that the respective leg 12th , 14th , 15th analogous to the leg 23 each the form-fit element 22nd represents or is formed by this.

This further material connection element 25th corresponds to a given material connection element 26th of the component housing 5 , for example with a given one of the housing surface parts 6th . The material connection elements particularly preferably correspond 25th , 26th with each other in such a way that they coincide as soon as the contacting device 1 and the commercially available component 4th to the component 2 are composed. This can be the case with the material connection element 25th of the fastener 10 or the contacting device 1 or the contacting body 8th be an adhesive that is used when assembling the contacting device 1 with the component 4th in direct contact with the material connection element 26th of the component housing 5 is brought. So go the material connection element 26th of the component housing 5 or the corresponding housing surface part 6th and the contacting body 8th at least in the area in which the contacting body 8th the material connection element 25th has a cohesive connection with one another. The respective contacting body is in this way 8th particularly secure on the component 4th or on its component housing 5 held.

In 7th is a schematic side view of the contacting body 8th in a further embodiment of the contacting device 1 shown. In contrast to the embodiments of the contacting device described up to now 1 is in the embodiment according to 7th provided that the respective spring element 9 on another part of the housing surface 6th of the component 4th is arranged as soon as the contacting device 1 and the commercially available component 4th to the component 2 are composed. So the section extends 19th that is the spring element 9 has or in which the spring element 9 is formed along another housing surface part 6th than in the embodiments of the contacting device described up to now 1 or the component 2 . Is the component housing 5 for example cuboid, the housing surface part 6th , which is parallel to the plane of the drawing in 7th is arranged, a broadside 27 of the cuboid or component housing 5 represent.

8th shows a schematic top view of the component 4th that by means of the contacting device 1 as in 7th is shown is modified. It can be seen here that the respective contacting body 8th two opposite legs 23 has that in the component 2 , that is, if the component 4th and the contacting body 8th connected to each other, respectively perpendicular to the other legs 12th , 14th , 15th are arranged. With the respective contacting body 8th has at least one of the fourth legs 23 the section 19th on, in which the respective spring element 9 is formed or arranged. Here is - like out 8th it can be seen - provided that the one of the fourth leg 23 who made the section 19th or the spring element 9 has, is longer than the other of the legs 23 . At a synopsis of the 8th with the 7th it becomes particularly clear that the commercially available component 4th can be used in a particularly space-saving or space-efficient manner, since the component has a thickness 2 between the spring elements 9 compared to a height above the pins or electrical connection elements 7th is particularly small. In other words, the component is 2 compared to the commercially available component 4th especially flat.

9 shows a schematic and sectional view of the assembly 3 that a variety of means of the contacting device 1 modified components 4th having. In other words, the assembly has 3 a variety of components 2 on. Furthermore, the assembly 3 an assembly housing 28 on, in which at least two of the electrical connection rails 13th are integrated. With one material of the electrical connection rails 13th , which can also be referred to as busbars, is an electrically conductive or conductive material, in particular a metal. The connecting rails 13th are within the assembly housing 28 guided or held, but are isolated from this, especially if the assembly housing 28 itself comprises a metallic material and is consequently designed to be electrically conductive or conductive. This is the case, for example, when the assembly housing 28 even an electrical function, for example a grounding function, takes over. In this case it can be provided that at least one inner surface 29 of the assembly housing 28 as one of the connecting rails 13th is formed or serves as such. It is provided in particular that the connecting rails 13th run parallel to each other and over a respective distance 30th are spaced from each other, which along a longitudinal direction of extension of the connecting rails 13th or the assembly housing 28 remains the same, especially in an interior 31 of the assembly housing 28 . This distance 30th is in 8th and corresponds to a thickness of the component 2 when the opposing or opposing spring elements 9 are at least partially excited.

At the in 8th spring element shown below 9 it can be seen that this is under tensioning of the same at a distance 32 indented that between the thigh 23 of the one contacting body 8th and that along the common housing surface part 6th directly adjacent leg 23 of the corresponding other contacting body 8th is trained. So is the component 2 between two connecting bars that are directly adjacent to one another 13th arranged, practice these two connecting bars 13th on the spring elements 9 a tension force, so that the respective spring element 9 is pressed into position and held there, as it is on the lower spring element 9 in 8th is shown. Because of this, the spring elements practice 9 then a spring force on the corresponding adjacent connecting rail 13th the end. This is between the component 2 and the two connecting bars that are directly adjacent to one another 13th a mechanical and electrical connection can be realized. Because the respective spring element 9 constantly strives to transition into a relaxed state, which is based on the in 8th spring element shown above 9 is shown. Because that in 8th the spring elements shown above 9 is shown in its at least substantially relaxed state.

To the assembly 3 , which can in particular be an electrical and / or electronic assembly, with at least one component 2 to be fitted so that this mechanically and electrically fits into the assembly 3 is integrated, it is provided that the respective component 2 along a fitting direction or insertion direction 33 via an open or openable end 34 of the assembly housing 28 in the interior 31 is inserted. For this purpose, due to the pushing in or under the pushing in of the component 2 or at least one of the spring elements in preparation for this insertion 9 , especially both spring elements 9 , so tensioned that the component 2 the distance 30th Has a corresponding or a smaller thickness, so that the component 2 between two of the connecting rails 13th can be used and finally pushed in. With the components 2 , in the 9 are shown, is thus the respective component 4th via the with the corresponding component housing 5 connected contacting device 1 on the connecting bars 13th (mechanically) held and electrically contacted.

As already described above, the respective component 4th around a capacitor element 35 or a coil element 36 Act. Accordingly, the in 9 Arrangement of the components shown 2 or the capacitor elements 35 or the coil elements 36 a filter assembly. This filter assembly has a common mode interference suppression element 37 as well as two push-pull interference suppression elements 38 on. This can be a ferrite ring that connects the connecting rails 13th encircled like a ring.

Are not shown for the assembly 3 or mounting aids for the filter assembly, for example plastic parts that do not fulfill any electrical function, but for example between two of the components that are directly adjacent to one another 2 in the interior 31 or between the respective connecting rails 13th can be arranged. These holding aids can have spring elements which at least essentially have a function of the spring elements described herein 9 correspond. Furthermore, the holding aids can have further form and / or frictional locking elements, by means of which the holding aids in the interior 31 of the assembly housing 28 held, for example, can be braced. By means of this mounting aid and at least one of the components 2 directly adjoining each other is a particularly firm or robust, that is to say in particular a more resistant seat of the components 2 in the interior 31 guaranteed.

The assembly 3 furthermore has a housing-side plug element or plug element 39 on, the one with a mains-side connector element 40 corresponds. This means that the connector element on the housing side 39 and the connector element on the network side 40 mechanically and electrically, in particular detachable in a non-destructive manner, can be plugged into one another. In the case of the plug element on the mains side 40 it can be, for example, a plug element of an electronic network into which the assembly 3 can be integrated or is integrated if the connector elements 39 , 40 are electrically and mechanically interconnected. Between the connector element on the housing side 39 and a base body of the assembly housing 28 can be a screw connection 41 be provided so that the housing-side connector element 39 particularly secure on the base body of the assembly housing 28 is held.

In this example, the assembly housing is 28 the assembly 3 or the filter assembly is at least partially made of electrically conductive or conductive material. This means that in the example of the filter assembly, the assembly housing 28 provides at least one electrical function, in the present case a grounding function of the filter assembly.

It should be understood that the filter assembly is just a single example of the assembly 3 represents. Of course there are other assemblies 3 conceivable that a large number of differently designed components 2 or components 4th have, for example the capacitor elements 35 who have favourited coil elements 36 , Resistors, transistors and / or other electrical or electronic components.

Overall, the invention shows how by means of the contacting device 1 the commercially available component 4th can be modified in a particularly advantageous manner, so that the assembly can be manufactured and / or reconfigured 3 and / or the component 2 is made possible particularly simply and with little effort. Thus, a particularly fast variant formation is possible through the spring contact by means of the spring elements 9 provided. The moreover one is the interior 31 of the assembly housing 28 , especially between the connecting rails 13th , particularly efficiently exploitable by a physical alignment of the component 4th through the contacting device 1 is changeable or is changed, the mechanical and / or electrical contact between the component 4th and the corresponding connection rails 13th remains guaranteed. Ultimately, a particularly economical, that is to say inexpensive, option is provided, commercially available components 4th to modify as required.
