[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal or abnormal circuit conditions. Circuit breakers are important electrical devices for the protection and operation of power systems, used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. Circuit breakers come in many structures and types, but they are basically composed of a conductive main circuit, insulating support components, an arc-extinguishing chamber, and an operating mechanism. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range.

[0003] When using existing circuit breakers, several circuit breakers are usually combined and spliced ​​together to work together to protect the circuit. However, when two circuit breakers are used together, their installation and fixation are unstable, which can cause them to shake relative to each other during operation, affecting their normal operation.

A mounting plate 3 is provided at the bottom of the first circuit breaker body 1 and the second circuit breaker body 2. The first circuit breaker body 1 and the second circuit breaker body 2 are parallelly snapped onto the top of the mounting plate 3. A connecting mechanism 4 is provided between the first circuit breaker body 1 and the second circuit breaker body 2. The connecting mechanism 4 includes a fixing block 41 and a snap-fit ​​block 42. The fixing block 41 is fixedly disposed on the side wall of the first circuit breaker body 1, and the snap-fit ​​block 42 is fixedly disposed on the side wall of the second circuit breaker body 2. The fixing block 41 and the snap-fit ​​block 42 are arranged opposite each other and are snapped together for fixation.

[0028] like Figures 5 to 7As shown, the fixing block 41 has two slots 411 on its side wall, and a first sliding groove 412 is provided at the bottom of the slots 411. Two first countersunk holes 414 are provided in the middle of the side wall of the fixing block 41. Screws are installed in the first countersunk holes 414, and the fixing block 41 is locked to the side wall of the first circuit breaker body 1 by passing two screws through the first countersunk holes 414. Two second through holes 201 are provided on the side wall of the second circuit breaker body 2, respectively opposite the two first countersunk holes 414, and the diameter of the second through holes 201 is larger than the diameter of the first countersunk holes 414. Each side wall of the slots 411 has a locking hole 413. A second sliding groove 421 is provided in the middle of the side wall of the locking block 42, which slides with the middle of the fixing block 41. Two notches 422 are provided on the side wall of the locking block 42, and the two notches 422 are symmetrical about the second sliding groove 421. There are two third sliding grooves 423, which are symmetrical about the center of the second sliding groove 421. The third sliding grooves 423 are located between the cutting groove 422 and the second sliding groove 421. The cross-sectional structure of the third sliding groove 423 is I-shaped. An adjustment part 43 is slidably arranged in the third sliding groove 423. The top of the snap-fit ​​block 42 is provided with a limiting protrusion 425. The side wall of the limiting protrusion 425 is provided with two second countersunk holes 426. Screws are provided in the second countersunk holes 426. The snap-fit ​​block 42 is locked and fixed to the side wall of the second circuit breaker body 2 by passing two screws through the second countersunk holes 426. The side wall of the first circuit breaker body 1 is provided with two first through holes 101. The two first through holes 101 are respectively opened opposite the two second countersunk holes 426, and the diameter of the first through holes 101 is larger than the diameter of the second countersunk holes 426. Both sides of the snap-fit ​​block 42 are provided with snap-fit ​​connectors 427, which are adapted to snap-fit ​​holes 413.

[0029] like Figure 5 As shown, the adjusting part 43 includes a slider 431, which is slidably disposed in the third groove 423. The slider 431 has a sliding hole 4311 on its side wall. The sliding hole 4311 is a square hole with a circular opening. An adjusting head 432 is slidably disposed in the sliding hole 4311. A slider 433 is disposed on the side wall of the adjusting head 432. The slider 433 has a square structure and is adapted to the shape of the sliding hole 4311. A spring 434 is disposed between the slider 433 and the adjusting head 432. The spring 434 is sleeved on the adjusting head 432. The slider 431 has a mounting hole 4312 on its front side. The groove 422 has connecting holes 424 on both side walls. A steel rope 435 is disposed in the mounting hole 4312. The other end of the steel rope 435 passes through the connecting hole 424 and extends to the other side wall of the groove 422.

[0030] Specifically, the implementation involves securing the fixing block 41 to the side wall of the first circuit breaker body 1 with screws passing through the first countersunk hole 414. The adjusting part 43 is installed into the third sliding groove 423 of the snap-fit ​​block 42. The snap-fit ​​block 42 is then secured to the side wall of the second circuit breaker body 2 with screws passing through the second countersunk hole 426. The snap-fit ​​block 42 then slides down along the slot 411 of the fixing block 41, while the adjusting head 432 of the adjusting part 43 slides along the first sliding groove 412. This double limiting enhances the smoothness of the sliding, preventing deviation during the sliding process and ensuring smooth operation. The sliding continues until the limiting protrusion 425 abuts against the top center of the fixing block 41. At this point, the snap-fit ​​head 427 engages in the snap-fit ​​hole 413, firmly securing the snap-fit ​​block 42 into the slot 411 of the fixing block 41. The first circuit breaker body 1 and the second circuit breaker body 2 are securely connected together to prevent relative displacement and wobbling during operation. The connection is stable and reliable. Finally, the two are snapped onto the mounting plate 3, making the connection convenient and quick. When the first circuit breaker body 1 or the second circuit breaker body 2 needs to be replaced, simply use a tool to remove the screws through the first through hole 101 and the second through hole 201. Disassembly and replacement are convenient and quick. When the connecting mechanism 4 needs to be replaced, use a tool to remove the first circuit breaker body 1 and the second circuit breaker body 2, pull out the adjusting head 432, and push it upward. The adjusting head 432 moves upward and pulls the steel rope 435, thereby causing the snap-fit ​​connector 427 to disengage from the snap-fit ​​hole 413. Continue to push the adjusting head 432 to separate the snap-fit ​​block 42 from the fixing block 41. After disassembly, the replacement can be performed.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
