Fuse insertion device

Abstract

A semi-automatic fuse and cap insertion tool includes a socket mounted on a rotatable shaft, which shaft is mounted in a gun-like holder structure. A resilient means between the shaft and the holder keeps the shaft in a first position. With a fuse and cap in said socket and the gun shaft aimed for linear movement toward the fuse block, a linear pressure force in the direction of the fuse and cap and release of a trigger latch means causes the shaft to move into a gun-like barrel recess in the holder to a second position. During such movement, a cam follower fixed in the gun barrel interior rides in a helical grove in the shaft to cause the shaft fuse and cap in this socket to rotate relative to the gun-like structure and lock the fuse in the block. In a first position, the trigger initially blocks movement of the shaft and the shaft in the first position to thereby allow a certain amount of pressure to be applied to move the fuse and cap into place in the block and against a spring in the fuse cap. Upon movement of the trigger to a second position, the shaft is released and the consequent rotation effects locking of the fuse cap in a fuse block. Springs between the shaft and the holder returns the shaft to its original first position and a spring between the holder and the trigger returns the trigger to its first position so that the shaft and socket are ready for the next repetition.
