ABSTRACT:
A connector device for splicing two conductors includes a pair of joined body sections provided with axially offset cable conductor holes leading to an intermediate cavity. A grip element with the cavity, having one or more helical coils has its opposite ends anchored relative to the opposed end faces of the two body sections. Two cable conductors are electrically and mechanically joined by inserting the conductor ends through the body sections and into the cavity, within the confines of the grip element coils following which, twisting of the body sections relative one another constricts the grip element convolutions tightly about the contained conductor ends. The interlock may be further enhanced by the inclusion of a knobbed lock post disposed within the connector cavity and which assists in deforming the conductor ends as the coil grip element is constricted thereabout.
