Electrical connector with strain relief

Claim 1

An electrical connector including a housing moulded from insulating material with a wall defining a cable receiving cavity extending between front and rear ends of the housing and opening at a cable admitting mouth at the rear end, a well extending through the housing wall to the cavity, a stuffer strip moulded from resilient material with a bulbous cable engaging face and a recessed opposite face, the cable engaging face of the stuffer strip having a pair of surfaces tapering symmetrically from respective longitudinal edges to an apex extending longitudinally of the strip, latching shoulders extending along opposite longitudinal edges of the stuffer strip between the faces, the stuffer strip being retained in the well with the edges engaging front and rear walls of the well in an interference fit in a cable admitting condition of the connector and forcibly movable down the well into a cable clamping condition in which the cable engaging face is in compressive engagement with a cable admitted into the cavity and abutting a wall of the cavity below the well and the shoulders latch with a snap action under front and rear walls of the well, the surfaces forming the taper being deformed inwardly into a concave configuration by engagement with the cable.
