Abstract
A panel mounted fuseholder has a cylindrical base and a head which fits into and locks unto the base by a shock proof, bayonet connection. The base has a rear terminal and a cylindrical side terminal for connection of the fuseholder in series with the circuit to be protected. The head has an insulative endcap and a conductive bayonet insert. A pair of "U" shaped fingers extend from one edge of the cylindrical side terminal to form the base side of the bayonet connection. The head side is formed by a pair "J" shaped arms which extend from one end of the bayonet insert. Protrusions extend from the interior surface of the bight of the "U" shaped fingers. The protrusions are dimensioned to make continuous contact with the outside surface of the "J" shaped arms when the arms are inserted within the fingers to thereby prevent loss of power to the protected circuit.
