US 2018/0294629 A1 · DEVICE AND METHOD FOR SPLICING SHIELDED WIRE CABLES

Abstract

A wire cable assembly, such as those used in electric or hybrid electric vehicles, having a plurality of shielded wire cables that are spliced together is presented. The assembly incudes a splicing device having a generally planar bus bar formed of a conductive material enclosed within an insulative inner housing. The inner housing is preferably tamper proof. The exposed core conductors of the shielded wire cables are welded to the bus bar, thereby electrically interconnecting the exposed core conductors. A conductive sleeve encloses bus bar and interconnects the shield conductors of the shielded wire cables, providing shielding for the exposed core conductors and continuity for the shield conductors. An outer insulator enclosing the conductive sleeve. A method of splicing shielded wire cables using such a device is also presented herein.
