[0002] A circuit breaker switch is an electrical protection device designed to prevent damage to the electrical system during circuit overload or short circuit. When the current exceeds the preset value, the circuit breaker will automatically disconnect the circuit, thus protecting the equipment and lines from damage. It can be reset manually or automatically and is a key component to ensure the safe operation of the electrical system.

[0003] Existing circuit breaker switches generally need to be fixed on the mounting surface through multiple sets of matching screws to achieve the installation operation. However, this increases the complexity during installation, making maintenance and replacement more difficult. At the same time, uneven distribution of the screws will lead to uneven pressure distribution of the circuit breaker, thus affecting its performance and service life. In view of the above problems, those skilled in the art have proposed a magnetically controlled circuit breaker switch module to solve the above problems. Summary of the Utility Model

The limiting components are used to assist in fixing the circuit.

[0006] Further, the limiting component includes a fixing plate and a moving plate. The fixing plate is fixedly connected to the outside of the circuit breaker switch body, the moving plate is slidably connected to the outside of the circuit breaker switch body, and moving rods are fixedly connected to both ends of the moving plate. Multiple moving grooves are opened on the surface of the moving rods.

[0007] Furthermore, support blocks are fixedly connected to the outside of the circuit breaker switch body, below both ends of the fixing plate. The top of the support block is rotatably connected to a movable plate. One end of the movable plate is fixedly connected to a second spring, and the other end of the movable plate is rotatably connected to a latch block.

[0008] Furthermore, one end of the push rod extends to the outside of the fixed block, and the outside of the push rod is slidably connected to the inside of the fixed block.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 、 Figure 2 And Figure 5 , an embodiment provided by the present utility model: A magnetically controlled circuit breaker switch module includes a circuit breaker switch body 1 and a mounting plate 2. A limiting groove 5 is opened at the bottom of the circuit breaker switch body 1. A limiting block 4 is fixedly connected to the top of the mounting plate 2. The limiting block 4 is slidably connected inside the limiting groove 5. Fixed blocks 3 are fixedly connected to both sides of the top of the mounting plate 2. A cavity 6 is opened inside the fixed block 3. A slide block 7 is slidably connected inside the cavity 6. A push rod 8 is fixedly connected to the upper side of the slide block 7. A connecting rod 9 is rotatably connected to the bottom of the slide block 7. The other end of the connecting rod 9 is rotatably connected to an insertion rod 10. A first spring 11 is fixedly connected to one side of the insertion rod 10. Insertion slots 12 are opened on both sides of the circuit breaker switch body 1 close to the fixed blocks 3. Limiting components are arranged on both outer sides of the circuit breaker switch body 1 for assisting in fixing the circuit.

[0025] Specifically, through the cooperation of the limit block 4 and the limit slot 5, the circuit breaker switch body 1 can be inserted into the top of the mounting plate 2, and the longitudinal section of the limit block 4 is a parallelogram, which matches the shape of the longitudinal section of the limit slot 5, so that the circuit breaker switch body 1 is more difficult to disengage after being fixed. By pressing the push rods 8 on the two fixing blocks 3, the push rods 8 are made to push the sliders 7 to slide inside the cavity 6, and then one end of the connecting rod 9 is pushed to move, so that the other end of the connecting rod 9 pushes the insertion rod 10 to slide and presses the first spring 11 to contract. At this time, it is convenient to insert the limit block 4 on the surface of the mounting plate 2 into the limit slot 5 at the bottom of the circuit breaker switch body 1. The first spring 11 can push the insertion rod 10 to insert into the inside of the slot 12 by its resilience, so as to realize the installation and fixation of the circuit breaker switch body 1, complete the installation of the circuit breaker switch. The circuit breaker switch body 1 can be disassembled or installed by means of clamping, which reduces the time consumed for disassembly and installation, is convenient for maintenance and replacement, and improves the efficiency of maintenance.

[0026] Refer to Figure 2 and Figure 4 , the limit assembly includes a fixing plate 13 and a moving plate 14. The fixing plate 13 is fixedly connected to the outside of the circuit breaker switch body 1, the moving plate 14 is slidably connected to the outside of the circuit breaker switch body 1, both ends of the moving plate 14 are fixedly connected with moving rods 18, and a plurality of moving rods 18 are provided on the surface of the moving rods 18. Below both ends of the fixing plate 13 near the outside of the circuit breaker switch body 1, support blocks 15 are fixedly connected. The top end of the support block 15 is rotatably connected with a movable plate 16. One end of the movable plate 16 is fixedly connected with a second spring 17. The other end of the movable plate 16 is rotatably connected with a clamping block 19. The outside of the moving rod 18 is slidably connected to the inside of the fixing plate 13. One end of the second spring 17 is fixedly connected to the outside of the circuit breaker switch body 1, and the outside of the clamping block 19 is engaged with the inside of the card slot 20.

[0027] Specifically, the support block 15 supports the movable plate 16, so that when one end of the movable plate 16 is pressed, it will rotate, causing the second spring 17 to be stressed and contract. By pushing the moving plate 14, the moving rod 18 can be made to slide inside the fixing plate 13. Furthermore, in cooperation with the fixing plate 13, the wire harness inserted into the interface can be limited, and the second spring 17 can make the clamping block 19 insert into one of the card slots 20 by its resilience, so that the fixing plate 13 and the limit block 4 clamp the wire, thereby pre-fixing the wire harness, which is convenient for the staff to connect and fix multiple wire harnesses to the circuit breaker switch body 1 at the same time, improves the installation efficiency, and improves the aesthetics after the wire harness is connected.

[0028] Refer to Figure 1 and Figure 5, one end of the push rod 8 extends to the outside of the fixed block 3, the outside of the push rod 8 is slidably connected to the inside of the fixed block 3, one end of the first spring 11 is fixedly connected to the inner wall of the cavity 6, the insertion rod 10 is slidably connected to the inside of the cavity 6, and the insertion rod 10 is in plug-in fit with the adjacent side slot 12. Mounting holes 21 are provided at the four corners of the mounting plate 2.

[0029] Specifically, the slider 7 can be pushed by the push rod 8 to realize the disassembly and assembly operations of the circuit breaker switch body 1. By fixing one end of the first spring 11, its stable contraction can be ensured. At the same time, the cavity 6 can limit the movement of the insertion rod 10, thereby improving the stability of the structure operation. Through the plug-in fit between the insertion rod 10 and the slot 12, the fixation of the circuit breaker switch body 1 is realized. The mounting plate 2 can be fixed on the mounting surface through multiple mounting holes 21, which is convenient for the installation and disassembly of the circuit breaker switch.

[0030] Working principle: When installing the circuit breaker switch body 1, first press the push rods 8 on the two fixed blocks 3, so that the push rods 8 push the slider 7 to slide inside the cavity 6, and then push one end of the connecting rod 9 to move, so that the other end of it pushes the insertion rod 10 to slide inside the cavity 6, pressing the first spring 11 to make it contract. At this time, the limiting block 4 on the surface of the mounting plate 2 can be inserted into the limiting groove 5 at the bottom of the circuit breaker switch body 1. When the two ends of the circuit breaker switch body 1 are aligned with the two ends of the mounting plate 2, release the push rod 8 to make the first spring 11 rebound, and then push the insertion rod 10 to insert into the inside of the slot 12, thereby realizing the installation and fixation of the circuit breaker switch body 1, and fixing the mounting plate 2 on the mounting surface through screws passing through the mounting holes 21 to complete the installation of the circuit breaker switch. The disassembly or installation of the circuit breaker switch body 1 is facilitated by the clamping method, reducing the time consumed for disassembly and assembly, being convenient for maintenance and replacement, and improving the maintenance efficiency. Secondly, when wiring, the wire harness can be inserted into the connection hole on the side of the circuit breaker switch body 1. By pressing one end of the movable plate 16 to make the second spring 17 contract, the clamping block 19 is driven to disengage from the card slot 20. At this time, the moving plate 14 can be pushed to make the moving rod 18 move. Then, after clamping by the moving plate 14 and the fixed plate 13, the second spring 17 can be released, so that the clamping block 19 is inserted into one of the card slots 20 to complete the clamping, which can limit multiple wire harnesses and realize the pre-fixation of the wires, facilitating the staff to fix the wires on the circuit breaker switch and improving the wiring efficiency.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
