ABSTRACT:
An improved device for relieving stresses on electrical connections between external cables and load circuits is disclosed. A two-piece bushing holder clamps the cable in position rather than using friction fittings as in earlier designs. Alternating downward and upward protrusions force the cable to assume a serpentine shape having alternating peaks and valleys within the bushing holder, substantially preventing movement of the cable and breakage of its connection to the load. The device is well-suited for use with portable loads such as industrial work lamps, which loads are subjected to severe stresses, as use of the clamping mechanism increases the force required to dislodge the cable and open the electrical connection. The device also may be made watertight according to certain industry and government specifications and less likely to ignite any combustable gasses present, making it suitable for use in hazardous environments as well.
