ABSTRACT:
This connecting unit for dispatchers systems comprises means for connecting a predetermined number of line wires.
It comprises stacked pairs of insulating supports 1, 2 kept in spaced relationship to each other by means of ribs extending from one face of a support, in each pair. The face 1' of insulating support 1 carries for example a conductor 11 of which a first end constitutes an input E1 and the second end is bent at Eb1. Similarly, the face 2' of insulating support 2 carries a corresponding conductor 21 of which a first end constitutes an output S 1 and a second end is welded at Sb 1 in front of Eb1. The bent end Eb1, in the inoperative position, bears against a portion 43 of a ground circuit 40. A module may be plugged in between the insulating supports 1 and 2 for co-operating with Eb1, Sb1 and portion 43. It may also co-operate with contact blades 42 and 51 connected to ground and signal circuits, respectively, provided on the insulating supports 1 and 2. The unit is intended more particularly for systems in which a great number of line wires have to be connected within a relatively reduced volume.
