Conductor surfaces, placed one on top of the other in such a way that the metal strips are aligned, as shown in Fig. 2 shows. The metal strips of the two multiple conductors are in place then get in touch.

The connection of the Pig. 5 and 4 has a first body 6 made of insulation material (Jig. 3) _t and an insert body 7, which is rorzugswtiee, but not necessarily, also made of insulation material. The body 6 has an elongated recess 8, the side walls of which are preferably toothed in such a way that that they alternately have longer flanks 9 running obliquely downwards and shorter flanks IO, which can be oriented parallel to the bottom 11 of the depression or also slightly upwards.

Pressure is pressed into the cavity until a firm hold is achieved. It is on the basis that the elastic deformation of one of the two bodies 6, 7 or both bodies of the electrical contact holder is rorteilait, in order to ensure a permanent solid cohesion of the multiple conductors with certainty. For this purpose, the two bodies can be formed from Hylon .

Shape, size and umber of the teeth on the side walls of the recess 8 and the insert body * 7 are so chosen that comes about with certainty a fixed handle on conductors of different thickness. To apply the necessary pressure when joining the two bodies, a pressure lever or a screw press can be used, which can be arranged in a stationary or movable manner.

The electrical line connection described above can be modified in such a way that it is used for establishing contact between the metal strips as a laaellen- shaped multiple conductor and metallic Xontmlct elements, which may have serrated bands "in order to contact the multifunctional conductor; an oleo contact is in the pig. 6 and 7 shown. .

Similar contact elements, of which “is indicated further at 23, can be arranged at corresponding intervals along the counterbore 16 in the body 15 in order to produce an electrical connection for each conductor element of the multiple conductor. In this case, the connection parts of the successive contact elements are preferably offset from one another, as shown. If contact elements are arranged at close spacings in slots of the body, it may prove practical to give the recess in the body 15 flat side walls and leave it to the grip of the contact elements alone to hold the wedge-shaped insert body 20 in a fixed position.
