Abstract

An in-line fused connector includes an outer housing and a fuse subassembly disposed in the outer housing. The fuse subassembly includes a mating terminal that is configured to engage a first conductive body of the power distribution module and an internal terminal coupled with the fused conductor that electrically couples with an electronic device. The mating terminal and the internal terminal are shaped to receive a fuse to electrically couple the mating terminal and the internal terminal. Electric current that is supplied by the power distribution module is conveyed through the fuse subassembly when the fuse subassembly receives the fuse and the mating terminal of the fuse subassembly mates with the first conductive body of the power distribution module through an opening in the front end of the housing. The fuse is removable from the fuse subassembly through the front end.

Claims
