Patent ID: 7241959

Claim:
A mechanical power breaker for a vehicle, comprising: a casing having a top and a bottom; a power input mounted to the casing; a master power output mounted to the casing; and a breaker being inside of the casing and electrically connected between the power input and the master power and comprising: a seat has an upper opening, a bottom, a through hole defined in the bottom and a pillar that is conductive, electrically connected to the master power output and has an upper and bottom sides, wherein the upper side and lower side of the pillar are respectively and securely connected between the bottom of the seat and the bottom of the casing; a conductive connector positioned in the through hole of the seat to connect to the pillar and consisted of multiple conductive blocks stacked to form a separable long pillar; a hollow moving element put on the bottom of the seat and surrounded the conductive connector, wherein the hollow moving element has a width smaller than that of the seat, an upper surface and a lower surface; a first resilient support mounted on the top of the casing and extending into the casing to provide a pressing force to the top of the conductive connector; and multiple second resilient supports mounted on the top of the top of casing and extending into the casing to provide pressing forces to the top surface of the moving element in the seat; wherein in the event of vibration of the casing, the moving element is moved to hit said separable long pillar to separate said multiple conductive blocks to disconnect the electric connection between the power input and the master power output.
