ABSTRACT:
An improved conductor clamp adapted to securely clamp conductors having various sized diameters. The clamp includes a first pair of generally rectangular bar clamping members movable in a first direction toward each other and in an opposite direction away from each other. Each of the first pair of clamping members have a pair of parallel generally V-shaped grooves extending the length of the member with a conductor contact portion provided therebetween. A second pair of opposite clamping members is positioned intermediate the first pair of clamping members. The second pair of clamping members each include a tail portion and a head portion having a conductor contact portion. The second pair of clamping members are positioned and the head portions are configured to be received within the generally V-shaped grooves of the first pair of clamping members such that movement of said first pair of clamping members past a predetermined point toward each other results in similar movement of the second pair of contact members toward each other to readily accommodate conductors of various sizes.
