ABSTRACT:
An electrically conductive contact pin having a temperature fuse function includes an electricity conducting element formed in an approximately cylindrical shape divided into an electrode contact portion and an outer electric contact portion, a holding body for holding the electricity conducting element provided around the outer electric contact portion such that the holding body may slide along the surface of the outer contact portion, a pressing member for pressing the outer electric contact portion upward provided between the holding body and the electrode contact portion, and an actuator for actuating to expand the distance between the electrode contact portion and the outer electric contact portion upon melting of the heat sensitive electrically conductive melt body. The electrically conductive contact pin may be consisted of two electricity conducting route by having a measurement element inside. The measurement element is electrically insulated from the electricity conducting element and may be electrically disconnected together with the electricity conducting element by the operation of the actuator.
