When the connecting part is pressed flat, the film, which is the actual circuit part, protruding strips 5 slip or is damaged, so that the connection Ren width of the width of the bracket 4 corresponds. on is up to all requirements and even these protruding strips are larger in area Stress a long service life afflicted printed conductor tracks 6, which for the sits. 5 connection part 2 are determined.

In the following, the invention will be explained with reference to the method described in To establish the connection between others Embodiments illustrated in the drawing, the end part 2 and strip 5 are initially inserted into the purifies.

The well-known plug contact is therefore for the Bracket (4) has a meandering shape - used in foils with printed circuits takes and is therefore not suitable in its position against out- 35. pull is secured (Fig. 4). The object of the invention is to provide a useful Connection between foil and plug with the help of a V-shaped, electrically conductive clamp - create, even after long use, none 40 There is a risk of the film tearing and there is a good and perfect electrical contact It is already known to ensure foils with imprinted. Furthermore, the connection with Planar conductors can thereby be produced with the usual simple means without this To connect flat plugs firmly by using special special tools or any soldered joint 45 copper wire connections are required for the printed film, A piece of about 1.5 mm in diameter, which is used as a con- The flat plug socket for flexible printed clock piece is to serve, is placed and then the circuits is according to the invention to Festklemvier free-standing tabs of the male connector men the V-shaped, electrically conductive clip folded over in a known manner with special pliers and the connecting part of the film inserted into this around the piece of wire together with the connection 5 ° with the tail end attached to a deformable attachment to clamp the film. Provide such contradictions. The V-shaped bracket can be made from bindings come into consideration in particular, consist of a bent sheet metal lamella and on her when flexible, with a printed circuit, inside to hold the inserted film Foils can be roughened or provided with thorns or spikes in place of the otherwise usual cables, Treading trees, as is already the case today, especially in 55 The V-shaped bracket is expedient Motor vehicle construction is the case. tabs bent up at right angles on their sides, However, this known connection has a considerable amount of guidance and stops when it is pushed in Disadvantages, on the one hand, because a special piece of wire is used in the connector part of the socket. Pickled around the one must be that no part of the plug pushing the flexible film into the connecting part of the kers is and with its edges. <In case of tensile stress, it is advisable to use the V-shape the film can tear, and mdge clip with lip-shaped extensions on the other hand, because the foil that is provided around the copper wire. The webs of the connection part of the socket inevitably has to be laid around when you are after inserting the bracket and the Fo-inserting can move so that the connection lie pressed flat, so that the inserted bracket a does not lie in the plane of the printed film. 65 assumes a meandering shape and thus in its Furthermore, an electrical connection terminal is secured against being pulled out for the rer location. Connection of an electrical conductor to an electrical With the help of the arrangement according to the invention is trically conductive film known, in which the terminal avoided in a simple and advantageous manner that
