ELECTRICAL CONNECTOR Russian patent published in 1999 - IPC

FIELD: irreversible disconnection of electric circuits. SUBSTANCE: electrical connector includes plug and socket arranged in respective casings. Casings are embraced by captive nut made of material having shape memory effect with possibility of predetermined increase of length of its mean portion. The last is in the form of bellows, that is why it may be deformed with change of its length and shape and restored at increasing temperature of construction until threshold values. EFFECT: possibility of using electrical connector as pickup for detecting critical temperature increase and providing disconnection of electrical circuits at heat influence causing damage. 2 cl, 1 dwg
