Beror the individual cable strands on soldering lugs soldered to the connector strip.

such a display form let eo not possible, all cables in a single soldering process, for example by dip soldering, connect with the connector lead sa. Furthermore, such an embodiment of a strain relief arrangement has the part that the relief effect is not always properly guaranteed, since only one bracket is provided in one piece on the main body of the connector lead. Finally, the feed direction for the cables can no longer be selected »da eie through the bracket, which is made in one piece with the base body, is set once and for all JLst.

Figure 1 shows part of a connector strip generally designated 1 »which has an insulating base body 2, one for receiving (not shown) Chamber serving contact springs in the form of a length groove 3 and contact lugs 4 for electrical connection with the cable parents.

On one long side of the base body 2 of the connector strip a fastening device 5 is provided, which at In the present embodiment, a bracket with two grooves is formed wix-d.
