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.

Claims4

Dependent claims

In a connector assembly for electrically and mechanically joining main and tap conductors, wherein there is a housing body presenting opposed generally arcuate angularly converging line receiving hook portions defining nest areas, said hook portions facing one another and bisected by a common center line plane, and a wedge block positioned within said housing body, the wedge block complementarily configured with the angularly converging line receiving nest areas for tightly wedging main and tap conductors into the housing body, the improvement comprising:

body surfaces defining a threaded receiving bore having a longitudinal axis lying laterally of said centerline plane and lying in a plane which is perpendicular to said centerline plane at a center line of said body;
a screw drive threadably interconnected to said threaded bore;
a floating interface interconnection between the screw drive and the wedge block, said interface interconnection characterized by a lateral lug portion on said wedge block, said lug portion having a lateral slot defined by a major axis transverse of said center line plane and a minor axis, the distance across said slot at the minor axis being about the same as the diameter of the screw drive, the spaced flange members carried by the screw drive, said interface interconnection lug portion and spaced flange members being further characterized by a freedom of the screw drive and lug portion to shift laterally but not longitudinally;
and
whereby the wedge block is driven in forward or reverse directions in response to rotational drive of said screw drive, and the wedge is nevertheless free to find its natural bedding relationship to the housing body.
