Definitions

• the present invention relates to a clamp connector for flex ribbon cable according to the preamble of claim 1.
• a connector is known from DE 100 06 1 12 AI.
• the present invention has for its object to improve a generic clamp connector so that a good electrical connection with low contact resistance and a quickly realized strain relief can be made without great preparation of the cable and handling is simplified with the Monta * g ⁇ e.
• the invention is based on the idea of clamping the flex ribbon cable ends to be connected between at least two bodies in such a way that the cables are pressed into a relief which forms "chicanes" which deform the cables, so that high pull-out forces are required to to detach the cables from the connector. Furthermore, the pre-locking position enables simple assembly, since the cable ends only have to be inserted into the preassembled connector up to a stop in order to then be fixed by pressing the connector bodies together.
• the invention is explained in more detail below on the basis of the description of exemplary embodiments with reference to the drawing. In it show:
• Figure 1 shows a first embodiment of the clamp connector according to the invention in a perspective view.
• FIG. 2 shows the basic body of the clamp connector according to FIG. 1;
• 3a to c show a section through the clamp connector according to FIG. 1 in the pre-locking position and in the final locking position;
• 5a to c show a second embodiment of a clamp connector according to the invention with a ground tap
• FIG. 6 shows a third embodiment of a connector according to the invention as a Y connector
• FIG. 7a to d show the connector according to FIG. 6 in the pre-latching position and in the end position in a perspective and inside cut view;
• FIG. 8 shows a fourth embodiment of a clamp connector according to the invention with a shield
• FIG. 9a to c the shield and the clamp connector according to Fig. 8 cut in the pre-locking and in the end position.
• Fig. 1 shows a perspective view of a first embodiment of a clamp connector according to the invention.
• the connector 1 has a base body 4 and a counter body 6.
• the flexible flat ribbon cables 2, 3 to be connected each have an area at their ends in which the conductor tracks to be connected are stripped.
• the flex ribbon cables 2, 3 to be connected are each plugged into the clamp from different sides - the 1 and the counter body 6, which is in this operation in a pre-locking division, in which it with the base body 4 has a sufficiently large insertion slot for the Flex ribbon cable 2, 3 forms, is then brought into its final locking position by pressing the base body and the counter body, whereby the connection is made.
• Fig. 2 shows the base body in a perspective view.
• the base body 4 consists of a base plate 10 and side walls 11a, 11b, on which locking lugs are attached, with which the counter body 6 can be locked in a pre-locking position and finally in the final locking position.
• Fig. 3 shows the clamp connector in perspective in longitudinal section.
• Fig. 3a shows the clamp connector in the pre-locking position, in which the flex ribbon cable 2, 3 can be inserted.
• 3b shows the clamp connector in the final locking position. It can be seen that the ribs 8 have now each pressed a flexible ribbon cable 2, 3 into a recess 7, which is designed here as a continuous slot. This causes kinks in the flat ribbon cables to run transversely to the longitudinal extension of the flexible flat cable, whereby pulling the flexible flat cable out of the latched connector bodies or counter bodies 4, 6 would only be possible by deforming the cable material. Only one (5a) of the spring elements 5 is shown at the outermost edge, a transverse rib 9 being recognizable in the counter body 6, on the side flanks of which the superimposed ends of the flexible ribbon cables 2, 3 lie. This increases the contact area, which can best be seen in FIG.
• Fig. 4 shows a clamp connector that is used as a ground connector, as known for example from DE 100 06 112 AI.
• a contact spring 12 which extends over the entire width of the flex ribbon cable 2, is formed in one piece with a connection end 12b led out of the base body 4.
• the contact spring 12 is cast in the base body 4.
• the spring is formed as a U-shaped sheet metal, the free leg 12a pressing against the flex ribbon cable 2 and making electrical contact with the connection end 12b via the stripped conductor tracks.
• a screwing eye 12c is also provided centrally in the connection end 12b.
• the connector has a strain relief, which is formed here by the transverse rib 8 and the corresponding recess 7 in the mating connector 6.
• the flexible ribbon cable 2 is inserted through a slot in the counter body 6 until it abuts an end stop 26 at the opposite end.
• the counter body 6 is pressed onto the base body 4 in the final locking position, where it locks as in the previously described embodiment, it can no longer be released from this position.
• This is not to be understood as restrictive in the context, since where it is desired the locking can be made releasable by means of appropriate tools or the like.
• 5a-c show a second embodiment of the clamp connector according to the invention.
• 5a shows a perspective view of the clamp connector in longitudinal section.
• this clamping connector has two counter bodies 6a, 6b which can be latched on the top and bottom of a base body.
• the Base body 4 has an opening 13 in its center, through which the stripped conductor tracks of the flex ribbon cables 2, 3 are brought into contact with one another. This is done via the spring elements 5, which are caulked in each of the counter bodies 6a and 6b.
• the strain relief takes place via lances 14, which are immersed in the slots 15 provided in the flexible ribbon cables 2, 3.
• End stops 17 are provided on the two counter bodies 6a, 6b, against which the head ends of the cables strike when the flexible ribbon cable is inserted into the connector in the pre-locking position.
• FIG. 5b shows the connector in the locked position.
• Fig. 5c shows that the upper spring element is designed as a spring contact led out laterally, wherein the lateral lead-out 16 represents a ground tap.
• the conductor tracks of the upper flex ribbon cable 3 shown in FIG. 5a are stripped on both sides. This ensures that a contact is made, both between the ground tap 16 and the conductor tracks of the flex ribbon cables 3 and 2.
• the conductor tracks can be metal strips made of a copper alloy or vapor-deposited, sputtered or in a method for applying conductor tracks which is common in the production of printed circuit boards.
• 5b and 5c show the clamp connector in the locked position.
• FIG. 6 shows a third embodiment of a clamp connector according to the invention, in which a flexible ribbon cable 19 is connected to two further flexible ribbon cables 2, 3.
• This embodiment is largely similar to that shown in Fig. 5, wherein essentially only a slot 18 is provided approximately in the meridian plane of the base body 4, through which the flex ribbon cable 19 is inserted until its head end has crossed the central opening 13 in the base body 4 and finally in a receiving groove 20 on the opposite edge of the opening 13 finds its end stop.
• the cable 19, like the cables 2 and 3, is secured by strain relief 14, 15, as described in connection with FIG. 5.
• 7a-d show the clamp connector according to FIG. 6 in the pre-locking position and end position, once in a perspective view and once in a longitudinal section.
• 7a shows the pre-locking position during which the flex ribbon cables 2, 3 and 19 can be inserted into the connector. All cables run against stops, as already mentioned in connection with FIG. 5.
• Fig. 7c shows the connector in the end position, which is also designed as inseparable from the previous exemplary embodiments.
• 7d shows how the spring elements here press all three flex ribbon cables 2, 3, 19 onto one another at one point. At the head end of the middle flex ribbon cable 19, strip conductors are stripped either only on the top, on the bottom or on both sides, as required.
• the spring elements 5 are designed in the form of a base plate 22, from which the springs 5 extend, as in the exemplary embodiment according to FIG. 5.
• the base plate 22 is at its front and rear ends in the direction of the flex ribbon cables 2, 3 ren end in the direction of the flex ribbon cable 2, 3 bent such that the bent ends of the two shields on the two counterparts 6a, 6b face each other and the respective flex ribbon cable clamps between them.
• the ends of the base plate 22 are guided through slots 23 in the base body 4.
• the ends of the base plate 22 are preferably designed as elastic spring arms 24.
• the end stops also provided here for the head ends of the flexible ribbon cables 2, 3 are formed on the base body 4.
