Title:
MOVING CONTACT OPERATING MECHANISM OF CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/135043
Kind Code:
A1
Abstract:
A moving contact operating mechanism of a circuit breaker. A moving contact base (2) is integrally provided with a mounting column (21); a lock catch (1) and a moving contact (3) are both movably sleeved on the mounting column (21); an upper end of the moving contact base (2) is provided with a sliding groove (211) in which an end of a connecting rod (4) of a circuit breaker can slide; the sliding groove (211) comprises a bent portion (2111) and a straight portion (2112); an abutting arm (11) is arranged at the upper end of the lock catch (1); and a lock catch push rod mechanism (7) comprises a push rod (72) and a spring (71). After the circuit breaker is tripped, the front end of the push rod (72) comes into contact with the side surface of the lock catch (1), the second end of the connecting rod (4) is locked at the bent portion (2111) of the sliding groove (211), and a handle (6) can then be pushed to close the circuit breaker. According to this solution, the present invention solves the problem in the prior art, and provides the moving contact operating mechanism of a circuit breaker, which can reduce the number of parts based on the principles of mechanics and mechanology, and allows metal or plastic particles to fall into corresponding grooves or gaps to avoid affecting the action of the moving contact.
