The strain plate 3 is bolted to the mounting half by bolts 12. The encompassing roll-formed rim 13 of the strain plate is pressed against the seal. Firstly, the mounting half 1 is bolted to the connector housing 6, whereby an enclosing groove 24 may be offered on the bottom side of the mounting half, in which groove a sealing ring 19 is inserted for sealing the inside house of the housing against overseas supplies and humidity. At the situation of the cable entry, there thus outcomes a troubleproof seal in opposition to the entry of international supplies or humidity. Thereby outcomes, on the one hand, a tight hold of the cable in the cable entry, and on the other hand, also a seal towards exterior influences, corresponding to mud and humidity. According to at least one embodiment of the invention it is possible that in an apparatus for cable entry, there may be inserted not only one single flat cable, but also several, parallel guided, "stacked-up" flat cables. FIGS. 16A, 16B, and 16C are views of the strain plate of the embodiment of FIGS. FIGS. 14A and 14B are views of the seal of the embodiment of FIGS.
FIGS. 15A and 15B are views of the pressure disk of the embodiment of FIGS. Another embodiment is particularly advantageous with respect to manufacturing and storage costs, because it can be utilized with a uniform cable entry for all attainable cable configurations or any variety of cables. As a way to facilitate better understanding of the embodiment of the assorted parts of the flat cable entry and their interactions. In order to realize a very good clamping action, the clamp four is supplied with a rib 16 extending in a transversal route to the cable, and the clamp 5 is provided with two stress ribs 17. Appropriate roundings on the ribs stop cable harm, whereby the externally facing edges 18 of the clamps, which face in the direction of the outgoing cable, are also supplied with roundings so as to prevent cable harm when the cable is bent. In order to acquire an optimum clamping, the bending-resistant clamp four is provided with a transversely extending rib 16, whereas the clamp 5, which can also be bending-resistant, has two ribs 17 at a distance from each other. For this function, one in every of the 2 clamps is provided with tap holes, and the posts and the opposite clamp is respectively supplied with openings for bolts 15. When the 2 clamps are bolted together, the flat cable 9 is clamped between them and held safely in place.
The mounting part 1 is furthermore provided with two perpendicular, lateral posts 14, to which the tensile stress relief clamps 4, 5 are fastened. According to the invention, the article is achieved whereby a frame-formed mounting part is supplied on which posts are arranged on opposite sides, and whereby in the bottom space of the mounting part there's supplied a cable passage dealing with within the path of the inner area of the housing; a groove with rim-side help shoulders for an insertable, elastic seal is provided within the mounting part; the seal is provided with an opening corresponding to the form of the cross-section of the flat cable; with interposition of the flat cable, the tensile stress relief clamps could be bolted along with the posts of the mounting half. Within the recess 103 of the mounting part 102 is inserted a seal a hundred and ten which is made from elastic material, similar to smooth rubber, foam rubber or the like. The pressure plate 3, which is previously slipped over the flat cable, is then bolted to the mounting half. The stress plate 3 is arranged over the seal. Furthermore, a pressure plate 112 is pushed over the cable and bolted to the mounting half by way of the bolts 113, that are threaded into the bores 108. An enclosing roll-formed rim 114 of the pressure plate presses thereby on the upper disk 111 which compresses the seal.
Bores 31 are provided for the fastening to the mounting part. Cable entries provided with tensile stress relief are usually recognized for spherical cables. This process tends to be costly and intricate as the soldering operation entails targeting the via holes of the flex cable to the solder tails after passing the cable via the connector's strain relief bar. The object of the invention is subsequently to offer a cable entry for flat cable, which is extensively tailored to the dimensions of flat cable (width/thickness), which presents ample safety in opposition to intrusion of international materials, and which, with respect to tensile stress, gives security for the cable, providing the inserted cable simultaneously also with safety in opposition to bending stresses. The invention refers to an apparatus for inserting a flat cable in wall openings, housing walls, and so forth., in particular for housings of connectors. Additionally, it additionally has to be assured that bending stresses don't cause cable damage. Cable entries must be sufficiently protected towards tensile stress of the cable with a view to avoid, in a given case, that the cable is not going to be pulled out of the housing or the cable entry machine, and that no inadequate tensile stresses occur at the locations of line connections.
