Extension terminals for universal circuit breakers

Abstract

The invention relates to an extended terminal of a universal circuit breaker, which includes an auxiliary contact, a mounting frame, a contact mounting fixture and a bending plate rotation drive device, and the contact mounting fixture includes a bending plate and two splints respectively fixedly installed on the mounting frame , the auxiliary contact is placed between the two splints, and the auxiliary contact and the two splints are positioned and connected between the two ends of the bent plate through the rotation axis, and the output end of the bent plate rotation drive device is connected to the bent plate. It can be seen that, In the present invention, the auxiliary contact is hinged in the contact installation fixture, and the bending plate constituting the contact installation fixture is driven to rotate, so as to realize the rotation of the auxiliary contact hinged at both ends of the bending plate, so as to achieve the conversion of the auxiliary contact Purpose, thus it can be seen that the present invention has the advantages of simple structure, strong versatility, and convenient assembly and disassembly.

Description

technical field [0001] The invention relates to low-voltage electrical components and equipment, in particular to an extension terminal used in conjunction with a universal circuit breaker. When the universal circuit breaker is turned on or off, the extension terminal outputs a switching signal. Background technique [0002] At present, the auxiliary contacts of universal circuit breakers are generally composed of micro switches with switching points. The number of auxiliary contacts is generally four normally open and four normally closed contacts. The auxiliary contacts with switching points, when used by users, Only one group of normally open or normally closed contacts in a group of micro switches can be used, and the contact capacity is very small, which cannot meet the increasingly higher power consumption requirements. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides the extension terminal of the universa...
