Abstract

A blown fuse indicating and/or striking assembly (10) is provided for a current limiting fuse (12) having a tubular casing (14) of insulating material, a pair of terminal caps (16) mounted on the ends of the casing (14) to close the ends thereof, a fuse link (20) conductively interconnecting the terminal caps (16) and an arc quenching filler material filling the casing (14) to embed the fuse link (20). The assembly (10) includes an indicator housing (26) supported by one of the end caps (16), a pin type indicator in the form of striker pin (32) positioned within the housing (26) and biased outwardly from the housing (26) to pierce a plate (54) provided at the outer end of the indicator housing (26) and a pair of members (40,42,70,72) formed of a non-conductive material and having corresponding openings in the form of holes (50, 52) or notches (74) with a fuseable wire (44) threaded through the openings to prevent relative movement between the members (40, 42), one of the members (40, 70) being supported by the housing and the other of the members (42, 72) being connected to the striker pin (32). On fusing of the wire (44) the member (42, 72) connected to the striker pin (32) is released allowing the striker pin (32) to move to the indicating position.In another embodiment, non-conductive members (60a, 60b) are formed from a split screw (60) and the wire (44) is wrapped around the threads (62) of the screw.
