Patent number: 12159764Abstract: A plug-in circuit breaker that includes a housing, an operating mechanism and a button mechanism which has a closing position and an opening position. The circuit breaker further includes a locking member and a linkage member arranged inside the housing. The linkage member is provided with an abutting protruding stand. The locking member is provided with a locking protruding stand. When the button mechanism is in the closing position, the abutting protruding stand of the linkage member extends out of the housing and is limited by the button mechanism at an extension position, so that it cannot retract into the housing. When the button mechanism is in the opening position, the linkage member retracts into the housing, the locking protruding stand of the locking member extends out of the housing, and the locking protruding stand of the locking member can be pushed back into the housing.Type: GrantFiled: November 14, 2020Date of Patent: December 3, 2024Assignee: ZHEJIANG CHINT & ELECTRICS CO., LTD.Inventors: Kejun Lu, Xiangyi Gu, An Yang, Jun Zhu, Shaojun Guo

Patent number: 12125655Abstract: A plug-in circuit breaker with an operating button that includes a button inner end inserted inside the circuit breaker and a button outer end. An indicator slot is arranged inside the operating button, an indicating hole is arranged on the button outer end. The plug-in circuit breaker further includes an indicating member slidably inserted inside the indicator slot and one end of which is provided with a make-contact indicating surface and a break-contact indicating surface. When the plug-in circuit breaker is in a break-contact state, the break-contact indicating surface is arranged opposite to the indicating hole, thus during pressing the operating button, the indicating member moves inside the indicator slot. After the make-contact state, the make-contact indicating surface is arranged opposite to the indicating hole. The indicating member is arranged inside the operating button to save space and to indicate the break-contact and make-contact state through the indicating hole.Type: GrantFiled: November 14, 2020Date of Patent: October 22, 2024Assignee: ZHEJIANG CHINT ELECTRICS CO., LTD.Inventors: Weijun Ge, Kejun Lu, Xiangyi Gu

Patent number: 12014891Abstract: A plug-in circuit breaker that includes a circuit breaker housing with a limiting hole and a opening and closing button. The circuit breaker further includes a locking member rotatably arranged inside the circuit breaker housing with an upper portion close to the limiting hole provided with a locking protrusion fitting. A lower portion of the circuit breaker housing is provided with a locking driving surface fitting with the opening and closing button. When the limiting hole is not shielded, the opening and closing button jacks up the locking driving surface to enable the locking protrusion to extend out of the limiting hole. The plug-in circuit breaker is closed when the limiting hole is shielded, so that the locking protrusion cannot extend out of the limiting hole. The locking driving surface limits the opening and closing button, so that the opening and closing button cannot press to the destined position.Type: GrantFiled: November 14, 2020Date of Patent: June 18, 2024Assignee: ZHEJIANG CHINT ELECTRICS CO., LTD.Inventors: Kejun Lu, Xiangyi Gu, An Yang, Jun Zhu, Shaojun Guo
