Abstract

An electrical connector assembly combines a latch (34) and electrical contacts (60a-60f) into an integral connector assembly. The latch (34) is partially surrounded by a stacked connector (36). The latch (34) lathes with a housing (22) and the stacked connector (36) includes a connector contact housing (40) that includes a plurality of stacked contacts (60a-60f) to provide an electrical connection between a first (60) and second (64) electrical circuit. In one embodiment, the connector contact housing (40) is in a “U” shape and partially surrounds at least a portion of the latch (34). The stacked connector (36) engages with a receptacle well (38) having a plurality of corresponding stacked receptacle contacts (62a-62f). The plurality of stacked contacts (60a-60f) is positioned in a manner to provide balanced contact loading along at least one axis (100) of the stacked connector (36). As such, in one embodiment, the stacked contacts (60a-60f) are arranged in an opposing manner.
