Abstract: A cable clamp particularly adapted for use with ribbon-type connectors is readily mounted on a connector end by means of a clamp anchor portion connected to a cable-supporting base having a projecting rib. Integral opposed side walls are adapted to move inwardly relative to the base and clampingly urge a cable, containing wires to be terminated in the connector, against such base over the projecting rib which extends transversely to the cable axis. Each side wall includes laterally extending ear portions for urging engaged cable portions downwardly on either side of the base rib so as to deform the cable over the rib and assure a secure cable-clamp engagement. Such engagement enables the cable and the individual wires to resist movement relative to the clamp upon the exertion of axial forces thereon, thereby functioning as an efficient strain relief preventing disruption of terminations of the wire conductors within the connector.

Clearances are provided internally at one end of the intermediate member to define a line of sight to visually check the integrity of the grounding contact. A nut shell containing an annular seal closes the line of sight after the visual check has been made.

Abstract: A male and female electrical connector are held together via a permanent magnet inside the female connector. The male connector is generally spherical and of ferrometallic construction so as to be attracted by the permanent magnet. A number of male connectors may be attached to a multi-conductor cable, each male connector being electrically connected to only one of the conductors. In this manner, a multitude of electrical connections can be made concurrently. The invention is especially suitable for use in medical applications requiring an electrical attachment to be made to a patient which may be easily disconnected by the patient when he so desires.

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.
