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.

In a terminal construction comprising a body having inner and outer sides and having an end wall with at least one aperture therethrough, a pin made of an electrically conductive material extending through said aperture in said end wall and extending a distance beyond said end wall on both sides thereof, said pin having inner and outer ends, the inner end of said pin being disposed on the inner side of said body, the outer end of said pin being disposed on the outer side of said body, a seal bonding said pin to said end wall, the improvement comprising said pin comprising first and second pin sections and an electrically conductive fusible section, said seal being bonded to said first pin section, said fusible section being disposed on the inner side of said body and interconnecting said first and second pin sections in substantially aligned relation at a point in the extent of said pin which is not bonded to said seal, said first and second pin sections being made of materials having melting points which are greater than the melting point of the material from which said seal is constructed, said fusible section being constructed and being made of a material having a melting point which is sufficiently less than the softening point of the material from which said seal is constructed so that when said pin is heated by the passage of current therethrough, said fusible section is melted to permit the separation of said first and second pin sections before said seal material is heated by said pin to its softening temperature.
