ABSTRACT:
An electrical jack module having a dielectric box-like housing with an end wall integrally joined to a side wall of the housing, the end wall having extended through its thickness a plurality of mutually spaced sleeves which define respective plug receiving apertures. The side wall has projecting integrally from its inner surface within the housing a plurality of rigid ramp-like detents, each of which is fixedly aligned with a respective one of the plug receiving apertures. Each of the detents has a lower end portion with a sloped surface merging with the inner surface of the side wall adjacent the respective aligned aperture, and has an opposing higher end portion with a surface terminating in an edge portion of the detent aligned with a sheer end surface thereof. The edge portion of the detent is spaced a predetermined distance from the respectively aligned aperture for buttingly engaging a specific portion of a fully inserted jack plug and for restraining withdrawal of the jack plug from the fully inserted position independently of any resilient restraining force exerted by electrical contact members of the module.
