ABSTRACT:
A terminal construction comprises a body having one or more apertures therethrough, a pin element in each of the apertures and a seal element in each of the apertures hermetically sealing and electrically insulating between the adjacent pin element and the body. Each of the pin elements comprises first and second pin sections and a fusible section which interconnects the first and second pin sections in substantially aligned relation at a point in the extent of the pin element where it is not bonded to the adjacent seal element. The fusible sections are made of a material having a melting point which is well below the softening point of the material from which the seal elements are constructed. Hence, when the terminal is operated under high temperature and/or electrical overload conditions wherein one or more of the terminals becomes overheated, the respective fusible sections of the overheated terminals are melted so that the pin sections thereby connected are separated to interrupt the flow of current through the terminal.
