Abstract: A vehicle circuit breaker includes a housing configured with a electrode assembly including a first electrode and second electrode; the first electrode is configured with a first conducting element and first insertion portion, and the second electrode is configured with an electrode connection portion and second insertion portion; a bimetal conducting sheet and blocking element are configured inside the housing, where the bimetal conducting sheet has a plurality of conducting concave portions for the installment of a second conducting element and the connection with the electrode connection portion, thereby carrying out a blocking action when current is abnormal and therefore making it easier for assembly.

Abstract: An electric coupling device includes a housing having a front socket opening and a rear chamber formed by two side wall. Two prongs are disposed in the socket opening of the housing and each has a free end extended out of the housing, and two conductor terminals are electrically coupled to the prongs, and a circuit breaker is coupled between one of the prongs and one of the conductor terminals and includes a conductor blade made of memorized material for selectively terminating or switching off the electric circuit between the conductor terminal and the prong when overheated or overloaded, and a reset knob may selectively and easily and readily switch on the electric circuit again.
