Abstract
A cable clamping device is integrally formed with a plastic electric box such as a switch box or the like. This clamping device is in the form of a finger member which is resiliently hinged to the box at one end thereof, and which resiliently moves on this hinge towards the interior of the box when urged by a cable end pressed against the outer wall of the clamping device. With such urging, the cable is permitted by the finger member to enter the box and is clamped between the finger and a wall of the box. A tab is provided on the free end of the clamping finger for use in prying the finger away from the cable. Stops are further provided along the inner wall of the finger clamp operating in conjunction with flat strip members which extend from an inner wall of the box to limit the inward travel of the finger clamp, thereby preventing overbending thereof. Further, the finger clamp is given resiliency along with high strength properties by molding a teardrop-shaped groove extending through half the thickness thereof and running between the opposite end of the finger, thereby providing a minimum cross section area at the end of the finger engaging the cable, to afford uniform bending throughout the lengthwise extent of the fingers to avoid overstressing of the cable at any single point.
