Auxiliary contact of miniature circuit breaker

Abstract

The invention discloses an auxiliary contact of a miniature circuit breaker. The auxiliary contact comprises a casing, an auxiliary contact handle, a plurality of clamping hooks and two miniature switches, wherein the casing has the shape of an oblate box with an opening on one side; the middle part of the auxiliary contact handle is hinged with the upper end part of the side face of the casing; a linkage rod is formed on the top of the auxiliary contact handle in a protruding mode; a stirring rod is formed on the lower part of the auxiliary contact handle in the protruding mode; the plurality of clamping hooks are arranged on the edges of two sides at the opening of the casing; the two miniature switches are arranged on the inner inside surface of the casing; contact arms on the miniature switches are positioned on the upper side; and the miniature switches are electrically connected with different kinds of control equipment respectively. The auxiliary contact and the switch handle on the miniature circuit breaker can act synchronously, so that the state of the miniature circuit breaker can be provided for a user in time by multiple kinds of external control equipment such as a signal lamp, a buzzer, a controller and the like which are connected with the miniature circuit breaker, the user can quickly know the state of the miniature circuit breaker even through the user is far away from the miniature circuit breaker, and faults can be removed in time once the faults occur. Therefore, the auxiliary contact of the miniature circuit breaker has high safety.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, in particular to an auxiliary contact of a miniature circuit breaker. Background technique [0002] Miniature circuit breakers, also known as miniature circuit breakers, are the most widely used terminal protection appliances in building electrical terminal power distribution devices. They are used to distribute, control and protect circuits and electrical equipment. They are mainly composed of housings, It consists of operating mechanism, tripping system, contact opening and closing system, arc extinguishing system and operating handle, wherein the operating handle is located on the top surface of the housing. But there is following problem in this miniature circuit breaker of prior art: this miniature circuit breaker is used alone usually at present, and there is no effective protective facility and indicating function on it, so if the user is far away from its position, once minia...
