摘要:
An improved cutout which accepts a fuse tube of standard length, which is less costly to manufacture and which exhibits improved performance, has an offset, rather than a straight, recoil bar. The offset positions the end of the recoil bar closer to the short leg of a J Spring, and positions a hole in the end of the recoil bar, through which freely passes a pin interconnecting the legs of the J, closer to a convexity in the short leg. Operation of the cutout causes a fuse tube, one end of which is in the concavity, to experience random longitudinal and transverse thrust forces. The offset limits the transverse motion the short J leg and the fuse tube can experience to (a) limit bending forces on the tube and breakage thereof, and (b) prevent the fuse tube from disengaging the concavity before the longitudinal thrust thereof subsides. The offset also ensures that longitudinal thrust forces on the tube are simultaneously transferred from the one end of the fuse tube to the recoil bar and from the other end of the tube to a contact assembly opposite from the recoil bar.
