Title:
CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/126821
Kind Code:
A1
Abstract:
A circuit breaker (10). The circuit breaker (10) comprises a housing (100) and a first wiring terminal (200), a second wiring terminal (300), a switch assembly (400), and a delay tripping mechanism (500) which are provided in the housing (100). The first wiring terminal (200), the switch assembly (400), and the second wiring terminal (300) are electrically connected in sequence to form a main circuit, and the switch assembly (400) is used for controlling the power on/off of the main circuit. The switch assembly (400) comprises a moving contact (410) and a static contact (430), and a wiring portion (411) is provided on the moving contact (410) in a protruding manner. The wiring portion (411) is electrically connected to the delay tripping mechanism (500) by means of a first wire; the wiring portion (411) is further electrically connected to the second wiring terminal (300) by means of a second wire, and the static contact (430) is electrically connected to the first wiring terminal (200). The circuit breaker (10) can improve the heat dissipation performance of the circuit breaker (10), thereby improving the reliability of the circuit breaker (10).
