Abstract

The invention discloses an auxiliary contact and a circuit breaker. A shell of the auxiliary contact is internally provided with two groups of wire holders and a lever group for controlling the closing and opening switching of the two groups of wire holders, the lever group is hinged on the shell and is provided with a first touch part and a second touch part, and the first touch part and the second touch part are respectively matched with the first elastic sheets of the first group of wire holders and the second elastic sheets of the second group of wire holders; the two elastic sheets are electrically connected with at least one of a corresponding second wiring terminal or a third wiring terminal, and according to the configuration, after the lever group rotates to switch the working positions, the follow-up touch parts are built after the elastic sheets are pressed against and deform. By applying the scheme, the configuration cost can be effectively reduced, and the space occupation can be reduced on the basis of satisfying the two-way indication function of the circuit breaker.

Description

technical field [0001] The invention relates to the technical field of contact devices, in particular to an auxiliary contact and a circuit breaker. Background technique [0002] The auxiliary contact device is the most common electrical device in the auxiliary unit of the circuit breaker. The common auxiliary contact device has a set of normally open and normally closed functions. For the situation of indicating the two-way breaking and closing of the circuit breaker, two auxiliary contacts need to be configured. Limited by the structural characteristics of the existing auxiliary contacts, the overall space occupation is relatively large, and the configuration cost cannot be effectively controlled. [0003] In view of this, it is urgent to optimize the design of the auxiliary contact to overcome the above-mentioned technical defects. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an auxiliary contact, wh...
