Description

The invention relates to a connector, in particular for contacting a differently designed contact points with electrical lines, with a plurality of contact elements, each with a plug-in area and have a connection area, and with one the contact elements receiving housing. The invention further relates to an arrangement the electrical such a connector and a contact points Has line.

Components are components under a connector in the above sense understood the allowed to connect an electrical line, and more are intended to establish and / or separate electrical connections. Such connectors are in a wide variety of embodiments for one Variety of applications known. They are usually large Quantity manufactured and are subject to their respective use the most diverse requirements, such as a simple and cost-effective production, large holding forces or a reliable Contacting.

As electrical cables are increasingly being used instead of assembled cable bundles Frequently flat ribbon cables application that consist of a flexible film. Such foil conductors, also known as "flex foil", have electrical conductors,  which are either within insulating film layers or on a Carrier film, such as printed conductor tracks, are. To contact the Foil conductor is known, the film with contact elements, for example Contact pins to penetrate. In addition, the film conductor on his Surface should also be provided with flat contact points, which are approximate Allow level contacting of the individual conductors. According to the Conductive electrical currents can be the individual conductors and then the Contact points of a film conductor can be designed differently by themselves for example, differ in width or thickness. Furthermore the individual conductors or the contact points can be different Have distances from each other. The latter is the case, for example, if signals of different frequencies in parallel by means of one and the same foil conductor should be transferred. Because in this case there are certain minimum distances must be observed in order to avoid mutual interference of the signals.

Accordingly, film conductors can be designed individually according to the respective application. To contact a film conductor, connectors in a wide variety of configurations are therefore required. This is all the more true for connectors, various connection technologies, for example screw connections, soldered connections or solderless connections according to IEC 352 or DIN EN 60352, such as crimp, clamp, winding, press-fit, insulation displacement, spring clamp and penetration connections, application Find. The production of numerous unequal connectors is complex and, like the stocking of the same, is unsatisfactory in economic terms.

The invention has for its object to provide a connector with which is reliable in a comparatively simple and inexpensive way Contacting a differently trained contact points can achieve electrical conduction.

To solve this problem is in accordance with claim 1 Connectors with the features mentioned in the introduction provided that the housing from several housing segments is composed, in each of which a contact element is arranged, and that the mating area of a contact element with a certain number  Contact sections is provided, the number of contact sections on the Width of a contact point to be contacted in the respective housing segment the electrical line is tunable.

A connector designed in this way is gaining knowledge peculiar that reliable contacting a differently trained Electrical line having contact points on comparatively simple and can be achieved inexpensively if the connector is modular is constructed. Because a modular structure allows an individual Requirements of corresponding connectors with little effort put together as required. According to the invention, the modular results Structure in that the housing from several housing segments is composed, in each of which a contact element is arranged. On this way the individual housing segments can be used as independent Prefabricated units and according to the number of contact points one to be assembled electrical line to be contacted. It is easily possible, contact elements with different plug and / or Provide connection areas to account for the respective requirements wear.

Contributes to the modular structure of the connector according to the invention at that the mating area of a contact element with a certain number Contact sections is provided. Because such a configuration enables from a manufacturing point of view, the number of Contact sections to the width of one in the respective housing segment coordinating contact point of the electrical line. This is for a reliable contact is essential.

Advantageous developments of the connector according to the invention represent the Objects of the subclaims. So it is about a simple one Manufacture of the contact elements particularly advantageous, the contact sections in to spaced apart from each other by a predetermined grid dimension. Because on this The plug-in area of the contact elements can be particularly easily connected to the Align the contact points of an electrical line to be contacted. reason this is, on the one hand, that the contact points regularly in a certain  Grid dimensions, for example according to DIN 40 801, are arranged, and on the other hand that due to the grid dimension a cheap to manufacture uniform arrangement of Contact sections results. A grid dimension of 0.5 mm, 0.635 mm is preferred (0.025 "), 1.0 mm, 1.25 mm, 1.27 mm (0.05"), 2.0 mm, 2.5 mm, 2.54 mm (0.1 "), 5.0 mm, 5.08 mm or a multiple thereof.

The plug-in area of the contact elements is expediently in the form of a spring contact trained, so that a reliable contact formed flat Contact points is ensured. It is also expedient, with regard to the usual Connection techniques for connectors the connection area of the contact elements to be designed as an insulation displacement clamp, crimp sleeve or solder connection. Alternatively, in this connection the connection area of the contact elements also as Be designed pin. In this case, it is made from manufacturing and assembly reasons advantageous, the connection area of the Arrange contact elements in a pin pan, which on the housing is fastened, for example, by latching.

In a preferred embodiment of the connector according to the invention the housing segments releasably connected to each other so that the housing easy to assemble and, for example for recycling, also convenient can be dismantled. To create a robust connection between the individual To achieve housing segments, the housing segments are with each other corresponding guide grooves and springs, which preferably a have dovetail cross-section, provided. Such Design also has the advantage that the individual Housing segments composite housing is relatively rigid, whereby one in the prior art is often associated with multicore Avoid central deflection of the connectors that can be observed leaves.

The housing segments are each advantageously provided with a slot, into the end section having the respective contact point contacting electrical line is insertable. Such an arrangement contributes to an easy-to-design contact holder, i.e. one Device by which the contact elements are held in the as  Contact carrier serving housing segments and ensures a reliable contacting of the contact points through the plug area of the Contact elements, especially when the plug-in area is preferred is designed as a spring contact. The slot is preferably continuous educated.

Alternatively, however, it can also be advantageous if the slot on at least one Side of the housing segments is closed. This is particularly useful for. Housing segments, which are arranged at the ends of the housing, so that the electrical line received in the slot has a lateral guide finds out when at least one end housing segment the closed Side. Nonetheless, one or more of the centrally arranged ones can also be used Housing segments have a laterally closed slot. In this case However, it is necessary that the electrical line with appropriate Recesses is provided in which the closed sides of the Intervene housing segments. In this way, the electrical line Center comfortably with respect to the housing, making it easy to insert the electrical cable is guaranteed in the slot of the connector.

According to a particularly advantageous development of the invention The connector segments are each with a clamp provided that at least partially in the respective slot of the Housing segments is arranged. Such a clamping piece is used to electrical line in the slot of the housing segments to the plug area of the Bring contact elements and pinch them. This happens especially then to be used if the connector is a zero force or ZIF connector (Zero Insertion force). Because in this case the Connectors, unlike LIF (Low Insertion Force) connectors be designed such that during a plug or No significant compressive or tensile forces occur. The Clamp allows the distance between the mating area of the Contact elements and a wall opposite this To dimension housing segments large enough so that the electrical cable can be inserted into the slot without resistance.  

A preferred structural design of the clamping piece consists in to form this in cross section U-shaped, with a first leg of the Clamp protruding into the slot and a second leg of the clamp the underside of a housing segment is arranged and wherein the second Leg of the clamping piece is provided with an opening by means of which Clamping piece can be positively attached to the underside of the housing segment is. To a relatively simple setting of the clamping pieces and thus one To ensure practical installation, it is advantageous to use the housing segments. to be provided with at least one cam on their underside. By the Engagement of the cam in one of the legs of the clamping pieces The intended opening results in a safe and reliable positive connection. If several cams are arranged one behind the other, it is also possible to to provide different locking positions for the clamping pieces, for example a and the same clamp for different thickness electrical To be able to use cables.

As a further development of the connector according to the invention proposed using the housing segments and / or the clamping pieces different colors to achieve a color coding, which prevents interchangeability.

To solve the above object is also in accordance with claim 17 in an arrangement with a connector that has a plurality of Contact elements, each a plug-in area and a connection area have, and a housing receiving the contact elements is provided, and provided according to the invention with an electrical line that the Housing of the connector from several housing segments is composed, in each of which a contact element is arranged, and that the mating area of a contact element with a certain number Contact sections is provided, the number of contact sections on the Width of a contact point to be contacted in the respective housing segment the electrical line is matched. Such an arrangement comes in Connection with the connector according to the invention discussed above Benefits.  

In a further development of the arrangement according to the invention, it is also proposed that the electrical line as differently designed contact points having flat ribbon cable, preferably as a foil conductor. Finally, it is proposed that the arrangement be a connector with the Features according to one of claims 2 to 16.

In Fig. 1 a formed as a flexible foil conductor 100 ribbon cable is illustrated. The film conductor 100 has electrical conductors embedded between insulating layers, which open out at one end section of the film conductor 100 into flat contact points 110 arranged on its upper side 101 . The contact points 110 are spaced apart from one another in different grid dimensions r and are also of different widths.

FIGS. 2a to 2e show the contact elements 200, which at one end a plug-in area for contacting the contact points 110 of foil conductor 100 and at the other end a terminal portion for electrical connection with some other electrical line, a circuit board or other electrical component exhibit. In all contact elements 200 according to FIGS . 2a to 2e, the plug-in area is designed as a spring contact 210 , which is composed of a predetermined number of contact sections 215 . The number of contact sections 215 depends on the width of the contact points 110 of a foil conductor to be contacted. Thereafter, the plug-in area can also have only a single contact section 215 , as can be seen in FIGS . 2a to 2d. In the case of a plug-in area having a plurality of contact sections 215 , the contact sections 215 are spaced apart from one another in a certain grid dimension, for example 2.5 mm. This makes it possible to manufacture the contact elements 200 in a cost effective manner as tape material, wherein the plug-in area required for a specific number is reached at contact portions 215 by appropriately cutting.

The connection area of the contact elements 200 can be designed differently with regard to the connection technology provided. Thus, the contact elements 200 according to FIG. 2a have a connection area designed as insulation displacement clamp 220 , the contact elements 200 according to FIG. 2b have a connection area designed as an open crimp sleeve 221 , the contact elements 200 according to FIGS. 2c and 2d each have a connection area designed as a solder connection 222 , 223 and the contact elements 200 according to FIG. 2e have a connection area designed as a plug pin 224 . The solder connections 222 , 223 shown in FIGS . 2c and 2d differ in the design of the solder connection pins. Depending on the application, these can be vertical, horizontal or angled. The horizontal or angled design is suitable, for example, for the widely used SMT (Surface Mounted Technology), in which surface-mountable components, generally referred to as SMD (Surface Mounted Devices), with solderable contact elements directly on connection points, so-called solder pads, on the surface of about one PCB can be applied.

In FIGS. 3a and 3b, a first embodiment is shown a connector for contacting the film fiber 100. The plug connector has a housing 300 , which is composed of four housing segments 311 to 314 which are detachably plugged together. As can be seen in particular from FIG. 3a, a contact element 200 is arranged in the housing segments 311 to 314 in the embodiment according to FIG. 2c. The size of the individual contact elements 200 at the same time from each other insulating housing segments 311 to 314 is determined by the number of the contact portions 215 of the respective plug-in regions 211 to 214 of the contact elements 200th

The housing segments 311 to 314 each have a slot 318 which is continuous in the two middle housing segments 312 and 313 and is closed on the outer side in the two outer housing segments 311 and 314 . The end portion of the film conductor 100 shown in FIG. 3a from its underside 102 and in FIG. 3b from its top 101 can be inserted into the slot 318 and is guided laterally through the closed sides of the outer housing segments 311 and 314 . The end section of the film conductor 100 is provided on its upper side 101 with contact points 111 to 114 , to whose respective width the plug-in area 211 to 214 of the contact elements 200 located in the assigned housing segments 311 to 314 is adapted. In this way, the contact points 111 to 114 of the film conductor 100 are reliably contacted in the slot 318 of the housing 300 by the corresponding plug-in area 211 to 214 of the contact elements 200 . In order to ensure a clear assignment of the contact points 111 to 114 to the respective plug-in areas 211 to 214 of the contact elements 200 , the individual housing segments 311 to 314 can be color-coded.

The second embodiment of a plug connector for contacting the foil conductor 100 shown in FIGS . 4a to 4f is designed as a ZIF plug connector. This means that the slot 318 has such a height that the film conductor 100 can be inserted without resistance. For reliable contacting of the contact points 111 to 114 of the film conductor by the. To ensure respective plug-in areas 211 to 214 of the contact elements 200 , a corresponding clamping piece 321 to 324 is provided for each housing segment 311 to 314 , which, after the film conductor 100 has been inserted into the slot 318 , is also inserted into the slot 318 in order to secure the respective To press contact points 111 to 114 of the film conductor 100 from its underside 102 onto the corresponding plug-in area 211 to 214 of the contact elements 200 and thereby to clamp the film conductor 100 in the slot 318 .

As can be seen particularly clearly in FIG. 4c, the clamping piece 320 is U-shaped in cross section. A first leg of the clamping piece 320 protrudes into the slot 320 , whereas a second leg of the clamping piece 320 is provided with an opening 325 . Two cams 315 arranged on the underside of the housing segment 310 engage in the opening 325 , so that the clamping piece 320 is positively fixed on the underside of the housing segment 310 . The clamping piece 320 is shown in FIG. 4c in a first latching position, in which only one of the two cams 315 engages in the opening 325 of the clamping piece 320 . In the present case, this first latching position only serves to hold the clamping piece 320 captively on the housing segment 310 . A resistance-free insertion of the film conductor 100 into the slot 318 is still possible in this locking position. Only in the second latching position shown in FIG. 4b, in which both cams 315 engage in the opening 325 , is the film conductor 100 clamped in the slot 318 . The first leg of the clamping piece 320 and the slot 318 can be, however, also be designed so that the contacting is effected to foil conductor 100 in the first latched position, a clamping of the film conductor 100, depending on the thickness.

FIGS. 4a to 4d also show clearly that the housing segments 311 are each provided on one side with the guide grooves 316 and on the opposite side with correspondingly shaped guide springs 317-314 and 310, respectively. The guide grooves 316 and the guide springs 317 serve to 310 by engaging the individual housing segments together to connect, respectively, the guide springs 317 of housing segment 310 in the corresponding guide grooves 316 of an adjacent housing segment 310th The guide grooves 316 and the guide springs 317 are dovetail-shaped in cross section. This ensures a secure positive fit between the individual housing segments 310 and an overall rigid construction of the housing 300 composed of the housing segments 310 or 311 to 314. The rigid design of the housing 300 also prevents the connector from bending in the middle at many contact points 110 of the film conductor 100 and thus in numerous housing segments 310 , as is often the case with known connectors.

In Figures 4e. 4f and the contacting of the devices connected to the foil conductor 100 connector is shown with a printed circuit board 400. As can be seen from FIG. 4f, the printed circuit board 400 has contact points 410 on the side facing away from the plug connector, which are electrically conductively connected to the connection area of the contact elements 200 designed as a solder connection 222 according to FIG. 2c. In this case, the circuit board 400 is contacted using the proven push-through technology. If the connector is not on the foil conductor 100 but on another circuit board 400 'is connected, resulting in the same way a "board-to-board" - connecting the two Leite plates 400, 400'.

FIGS. 5a to 5c show a third embodiment of a connector for contacting the film fiber 100. In contrast to the embodiments according to FIGS . 3a and 3b and 4a to 4f, the housing 300 of the connector according to the third embodiment is composed of only two housing segments 310 . In addition, the connection area of the contact elements 200 is designed as an open crimp sleeve 221 according to FIG. 2b, that is to say as a crimp sleeve which is open before crimping. To connect the wire 500 of an electrical line, the crimp sleeve 221 is deformed with the aid of a crimping tool. The stripped wire 510 of the wire 500 then forms a solderless electrical connection with the connection area of the contact elements 200 .

In Figs. 6a and 6b is shown to contact the foil conductor 100, a fourth embodiment of a connector. This connector has contact elements 200 , the connection area of which is designed as a plug pin 224 according to FIG. 2e. The plug pins 224 of the contact elements 200 are arranged in a pin trough 230 , which is fastened to the housing 300 , for example, by latching.

In the fifth embodiment of a plug connector for contacting the foil conductor 100 shown in FIG. 7, the connection area of the contact elements 200 is designed as an insulation displacement connector 200 according to FIG. 2a. By pressing the wire 500 into the insulation displacement clamp 200 , the insulating sleeve of the wire 500 is cut through and the stranded wire located inside the wire 500 is deformed. In this way, a gas-tight electrical connection, a so-called IDC (Insulation Displacement Connection), can be created.

Finally, FIG. 8 shows a sixth embodiment of a plug connector for contacting the foil conductor 100 . In this embodiment, the connection area of the contact elements 200 is designed as an angled solder connection 223 , as is also shown in FIG. 2d. The plug connector can thus be used as an SMD, which, by heating the contact points 410 of the printed circuit board 400 consisting of a layer of solder in this case, in addition to the electrical contacting of the contact points 410, also enables the mechanical fastening of the plug connector on the printed circuit board 400 without it being necessary, to pierce the circuit board. In this way, not only shorter assembly times but also significantly higher packing densities can be achieved on the printed circuit board 400 .

The connector described above is characterized in all embodiments by its modular structure, which results from the housing segments 310 to 314 assembled to form the housing 300 . The modular structure is further enhanced by the fact that a separate contact element 200 is arranged in each housing segment 310 to 314 , the plug-in area 210 to 214 of which is adapted to the contact points 110 to 114 of the foil conductor 100 to be contacted and the connection area 220 to 224 is designed for various connection techniques can be. The modular structure enables a relatively simple and inexpensive manufacture of individual connectors. Housing segments 310 to 314 can thus be prefabricated with different contact elements 200, and the required housing segments for film conductors 100 having different contact arrangements can be selected from this range and combined to form a corresponding housing. Last but not least, the connector described above also enables a "board-to-board" connection of two circuit boards without additional effort.
