ABSTRACT:
A clamp for an electrical cable which is particularly useful for fixing an electrical cable to a railway car truck. The clamp has an arched segment of a rigid sheet material which has a concave face, a convex face, opposed side flanks and open forward and rearward ends. The concave face and side flanks define an elongated concavity therebetween. An arcuate transition segment extends from each flank of the arched segment and connect to one of a pair of opposed flat wing segments. Each arcuate transition segment has at least one opening therethrough. Several detents project from the concave face into the concavity. A cincture such as a steel band extends through at least one opening in each arcuate transition segment and the opposite ends of the cincture are attached together. A helical spring having several windings is positioned in the concavity next to the concave face and extends from the forward end to the rearward end of the arched segment such that the detents project between the windings to prevent spring slippage. An electrical cable is mounted through the spring windings and extends from the forward end to the rearward end of the arched segment.
