The cutting and clamping contact elements 10 of the cable connecting member 1 have contact lugs 7, onto which bifurcated contacts 9 of the terminating element can be plugged. The terminating element is adapted as a plug connector receiving portion 2 with chambers 23 being open towards bottom, for the insertion of plug connectors 6 connected with the outgoing cable cores 37, and that the bifurcated contacts 9 are provided at the plug connectors 6.
Abstract:
In an impact protection cushion which can be accommodated in the steering wheel region for protection of the vehicle driver, a tearing seam is provided which joins the cushion upper part, which moves forward upon inflation, to the cushion lower part fastened to a fixed vehicle part. This arrangement prevents any radiating forward movement of parts of the cushion upper part, in particular, of a central region laying opposite the gas inflow opening in the cushion lower part without restraining straps.

Abstract:
The invention relates to a connecting block for connecting insulated cable conductors, in particular cable conductors of the telecommunication and data technology, comprising insulation displacement contact elements received in block bodies and arranged in lines. In order to provide a connecting block (1), wherein it is at any time possible to connect or disconnect cable conductors, without the block body (3, 4) impeding the connection of the cable conductors to the other block body (3, 4), at least one block body (3, 4) is provided with an axis of rotation (5), about which the block body can be swung out off the connecting block (1) or a connector arrangement is provided allowing relative movement between the block bodies.
Abstract:
The invention relates to a connector bank for conductors, in particular of telecommunication and data systems, comprising a bank body 6 with at least one line of insulation displacement contacts 4 provided with contact slots 5 for the conductors 7.According to the invention, there is provided for connecting shielded cables 22 a shield connecting element 1 consisting of a U-shaped, bent sheet piece 2, the legs 3 of which are insertable into the contact slots 5 of two insulation displacement contact elements 4 and the base 17 of which is provided with a shield connecting contact 19 for connecting the shield cable 21 of the cables 22, the spacing of the legs 3 corresponding at least to twice the spacing of two adjacent insulation displacement contact elements 4.
Abstract:
The invention relates to a meso-lactide having a melting point of 52.8.degree. C., processes for its preparation, and its use in the preparation of resorbable polymers and copolymers.
Abstract:
The invention relates to a cutting and clamping sleeve contact for contacting a cable wire laterally to the sleeve axis. The sleeve contact exhibits at least one clamping through slot at the periphery of the sleeve and a cutting and clamping contact in the interior of the sleeve. Wall pieces are cut free at the wall of a sleeve. They provide a one-piece sleeve contact suitable to contact cable wires having varying diameters and multi-stranded conductors. The wall pieces are also made of a metal material, and are bent into the interior of the sleeve and form contact legs for forming the cutting/clamping contact.
Abstract:
A connecting strip or receiver has switch contacts formed between break contact flaps which are arranged at a distance or spacing from each other, two interconnecting housing parts define a plug-in channel for a switch or a test plug which makes an electrical connection.The break contact flaps are positioned at a defined distance between them by housing inner walls which also define a plug-in conneciton channel.
Abstract:
The invention relates to a terminal strip or blocks in telecommunications, comprising a support plate with terminal elements for conductors to be plugged thereon and of a strip-like upper part to be snapped onto the support plate to create a relatively long terminal block without risk of addition of tolerance errors. The upper part is formed by several partial blocks, and the support plate has several receiving chambers arranged one behind the other for the partial blocks.
