ABSTRACT:
A simplified, low-cost connector assembly for attaching tap lines to overhead electrical main or tap conductors is provided which eliminates potential damage to the connected lines by provision of a cable-receiving housing and a complemental line-wedging block received therein along with means for gradually drawing the block into operative wedging position so as to preclude line damage. The assembly hereof preferably includes a tapered, generally transversely C-shaped, line-receiving housing, in conjunction with a complementally tapered wedge block and bolt means for gradually drawing the block into tight, line-connecting engagement with the respective cable sections received with the C-shaped housing. A reverse drive is provided by a laterally slotted lug on the wedge, the head of the bolt means and a lock nut providing forward and reverse drive with the lug. Torque limiting is accomplished by a replaceable frangible drive adaptor on the bolt head. The wedge is self-centering for bedding into the assembly with distributed forces.
