ABSTRACT:
A connector for electrical cables having a mechanism to prevent inadvertent disconnection. The connector includes a substantially solid block female component having a housing containing a concave, surface of revolution, curved surface with a plurality of electrical contacts on that surface and a substantially solid block male component having a housing containing a convex, corresponding surface of revolution, curved surface with a plurality of electrical contacts on that surface. One of those housings includes a pin spaced from and substantially parallel to the axis of the surface of revolution. The other housing typically has a pair of spaced notches in the housing at a corresponding distance from and substantially parallel to the axis of its surface of revolution. Thus, the notches can be engaged with the pin and the housings relatively rotated to bring the concave and convex surfaces and their associated electrical contacts into a wiping engagement. A releasable latch means is provided between the housings opposite the pin and notch. Electrical cables connected to the contacts enter the housings in the plane of the pin, so that the connector will not open in response to pulls on the cables. A light or lights may be provided to indicate that the connector or connectors are live. The engaging edges of the closed connector can be taped to prevent access of liquids to the contacts.
