  • Patent number: 3976351
    Abstract: The connector disclosed includes a body having a groove in which an electrical cable can be positioned. Electrical contacts are positioned in the groove with each contact having a sharp end for penetrating the insulation of the cable and engaging the electrical conductors of the cable. A movable cable clamping member is pivotally attached to the body to move the cable against the contacts to cause the contacts to penetrate the cable insulation and make electrical contact with the conductors. A cam arm is pivotally mounted on the body to move the clamping member. The arm has a cam surface in engagement with the clamping member that forces the member to force the cable into electrical contact with the contacts carried by the base member. When the cam arm has so moved the movable member, it is in an "over-the-center" position, which locks the clamping member in position holding the cable against the contacts and in the groove on the body.
