There are a variety of electrical connectors which electrically interconnect an uninsulated tap conductor wire to an uninsulated main conductor wire at a field site remote from a factory environment and using manual or portable power tools. One conventional type generally comprises a bolt which is split into two prongs extending upwardly from the bolt end. The prongs define a wire-receiving channel in which the main wire and an end portion of the tap wire are disposed. A nut is torqued onto the bifurcate bolt using conventional manual (or automatic) tools until a portion of the nut or an insert trapped in the bolt and nut assembly is pressed against a top one of the wires and urges the top wire against the bottom wire and the end of the bolt. One such connector is sold by Burndy Corporation, Norwalk, Connecticut under the trade name SERVIT Service Connectors. Such connectors are also disclosed in U.S. Pat. Nos. 1,873,559, 2,137,834, 2,164,006, 2,180,931, and 2,450,158.
These type of connectors are generally effective when the original termination occurs. However, after time the nut has a tendency to loosed, thereby allowing the wires to move away from each other resulting in an ineffective electrical connection. this problem is accelerated when the connector is exposed to harsh environments such as heat or vibration. It would, therefore, be beneficial to provide an electrical connector in which the nut is prevented from movement away from the wires.
