ABSTRACT:
A temperature responsive terminal pin construction having an aligned pair of terminal pin parts inserted in the opposite ends of a casing with the inner ends of the pin parts in spaced apart relation, a split ring collet surrounding the pin parts, the collet being axially displaceable under spring pressure from a first position of use in which the collet makes electrical contact with both pin parts to a second position in which the collet is out of contact with one of the pin parts, the collet being held in its first position by the nose of thermosensitive annular ring secured to the casing, the nose of the ring engaging an enlarged head on the collet. Excessive heating of the terminal pins will cause the nose of the thermosensitive ring to melt at a predetermined temperature to release the collet for axial movement. Coacting cam surfaces on the nose of the thermosensitive ring and the head of the collet act to urge the collet into tight electrical contact with the pin parts. The configuration of the pin parts facilitates the sealing of the terminal pin to a supporting body by means of a molded dielectric sealing member. Protective sleeves are provided for the inner pin parts in applications where conductive contaminants are encountered.
