ABSTRACT:
A combination fuse injector and ejector for cartridge type fuses includes a molded plastic open top receptacle, or shroud, having protective peripheral walls, a bottom wall and a hinged cover. The bottom wall includes an opening adjacent each end of the receptacle through which conventional fuse holding contact clips rigidly attached to a mounting surface can enter the receptacle. The bottom wall includes an integral external pedestal which provides a loosely coupled captive mounting for the receptacle on the mounting surface. The bottom wall of the shroud also includes a fuse-ejecting internal surface extending between the pair of contact clips whereby the fuse may be ejected from the clips by a lifting of the shroud on its loosely captive pedestal. The cover includes an integral class for lightly gripping the fuse to retain it during the ejection operation and to accept a replacement fuse for injection into the clips. The cover with the replacement fuse held in the claw is closed on the shroud and the entire assembly is returned to a mounted position on the mounting surface whereby the fuse is forced into the mounting clips.
