[0002] Miniature circuit breakers, also known as miniature circuit breakers, are suitable for overload and short-circuit protection of AC 50 / 60Hz lines with rated voltage of 230 / 400V and rated current up to 63A. They can also be used for infrequent switching of lines under normal conditions. Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings.
[0003] However, in most cases, workers use a rail-mounted method to attach miniature intelligent circuit breakers to rails. This method has certain drawbacks. For example, when a miniature intelligent circuit breaker malfunctions and needs to be disassembled for repair, it needs to be removed from the rail and then reinstalled. If other electrical components are installed on the rail, they also need to be removed, making the disassembly of the miniature intelligent circuit breaker more difficult. This is not conducive to saving time and reducing maintenance efficiency. Therefore, there is a need for a miniature circuit breaker that is easy to inspect and maintain. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0022] Please see Figure 1-3This utility model provides a technical solution: a miniature circuit breaker that is easy to maintain, including a mounting positioning plate 1 and a mounting positioning structure. The mounting positioning structure includes a mounting base 2, a receiving groove 6, a slider 7, an anti-slip plate 8, a second receiving groove 9, a limiting plate 10, a second limiting plate 11, a spring 12, and a limiting block 13. The mounting base 2 is fixedly connected to the surface of the mounting positioning plate 1. The receiving groove 6 is formed on the surface of the mounting base 2. The slider 7 is slidably connected to the inside of the receiving groove 6. The slider 7 and the receiving groove 6 are slidably connected. The anti-slip plate 8 is fixedly connected to the surface of the slider 7. The second receiving groove 9 is formed on the surface of the mounting base 2. The second receiving groove 9 and the receiving groove 11 are slidably connected. 6 are connected. Limiting plate 10 is fixedly connected to slider 7. Limiting plate 11 is fixedly connected to limiting plate 10. Spring 12 is fixedly connected inside limiting plate 10. Limiting block 13 is slidably connected inside limiting plate 10. Limiting block 13 is slidably connected to limiting plate 11. Limiting block 13 is fixedly connected to spring 12. There are two springs 12 and two limiting blocks 13, located on the upper and lower sides of limiting plate 10 respectively. Limiting block 13 has an inclined surface on the side near mounting base 2. Miniature circuit breaker body 3 is movably connected to the surface of mounting base 2. When installing miniature circuit breaker body 3, first push anti-slip plate 8 to drive slider 7. The sliding block 7 moves inside the receiving groove 6, causing the limiting plate 10 to move, which in turn causes the limiting block 13 to move inside the receiving groove 9. Because of the inclined surface of the limiting block 13, it can retract into the limiting plate 10, allowing the limiting plate 11 to enter the receiving groove 9. At this time, the miniature circuit breaker body 3 is installed onto the surface of the mounting base 2. The anti-slip plate 8 is pushed in the opposite direction, causing the limiting plate 10, the limiting plate 11, and the limiting block 13 to enter the miniature circuit breaker body 3. Due to the action of the spring 12, the limiting block 13 extends out and enters the miniature circuit breaker body 3, contacting the surface of the miniature circuit breaker body 3. The grooves are designed to fit the miniature circuit breaker body 3, thereby limiting its installation and positioning. For disassembly, simply push the anti-slip plate 8 to allow the limiting block 13 to enter the receiving groove 9, releasing the miniature circuit breaker body 3 from its limiting position. This allows for disassembly of the miniature circuit breaker body 3. The above structure makes installation and disassembly of the miniature circuit breaker body 3 easier, thus accelerating maintenance efficiency and providing convenience. It solves the problem of needing to disassemble other electrical components installed on the rail, making disassembly of the miniature intelligent circuit breaker more difficult and hindering time-saving and maintenance efficiency.
[0023] Furthermore, the surface of the miniature circuit breaker body 3 is fixedly connected with a protruding ridge 4, and the surface of the mounting base 2 is symmetrically provided with multiple slots 5 that are adapted to the protruding ridge 4. The protruding ridge 4 and the slots 5 make the installation of the miniature circuit breaker body 3 more stable and facilitate its installation and positioning. The limiting block 13 and the limiting plate 10 are slidably connected to the miniature circuit breaker body 3. The surface of the miniature circuit breaker body 3 is provided with a groove adapted to the limiting block 13. The surface of the miniature circuit breaker body 3 is provided with a connecting hole 15. The surface of the mounting positioning plate 1 is provided with multiple mounting screw holes 14. The mounting screw holes 14 are used to fix the mounting positioning plate 1 to the wall.
[0024] Working principle: When installing the miniature circuit breaker body 3, first push the anti-slip plate 8 to drive the slider 7 to slide. The slider 7 moves inside the receiving groove 6, driving the limiting plate 10 to move, which in turn drives the limiting block 13 to move inside the receiving groove 9. Due to the inclined surface of the limiting block 13, the limiting block 13 can retract into the limiting plate 10, allowing the limiting plate 11 to enter the receiving groove 9. At this time, install the miniature circuit breaker body 3 onto the surface of the mounting base 2, and push the anti-slip plate 8 in the opposite direction to allow the limiting plate 10, the limiting plate 11, and the limiting block 13 to enter the miniature circuit breaker body. Inside the body 3, the limiting block 13 extends out and enters the miniature circuit breaker body 3 due to the action of the spring 12, and matches the groove opened on the surface of the miniature circuit breaker body 3, thereby limiting the miniature circuit breaker body 3. This realizes the installation and positioning of the miniature circuit breaker body 3. When disassembling, simply push the anti-slip plate 8 to make the limiting block 13 enter the receiving groove 9, thereby releasing the limiting of the miniature circuit breaker body 3 and realizing the disassembly of the miniature circuit breaker body 3. The above structure makes the installation and disassembly of the miniature circuit breaker body 3 easier, which helps to speed up maintenance efficiency.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
