Electrical connector assembly for a truck-trailer jumper cable

Abstract

A light weight heavy duty electrical connector for a truck-trailer jumper cable which is constructed of a virtually indestructible plastic material resistant to corrosive chemical attack. The connector assembly includes an inner plastic body having a plurality of axially extending channels angularly spaced around the periphery thereof for receiving the individual conductors of the jumper cable and for mounting a corresponding plurality of resilient elongated split tubular electric contacts, each having a D-shaped cross-section and which are crimped to the respective conductors of the jumper cable. A removable plastic cap fits over the inner body to protect the contacts and to prevent short circuiting between the contacts. The inner body is received in an outer tubular plastic body having an integral funnel-shaped chamfer cable guard at the rear end thereof, with the jumper cable extending through the cable guard into the outer body. A transverse radially movable plastic clamp is mounted in the outer body adjacent to the rear end thereof for engaging the cable, and a set screw is threaded into the outer body to force the clamp against the cable without damage to the cable, thereby enabling the cable to hold the inner body and cap against axial movement with respect to the outer body.
