[0002] The leakage protector, also known as the leakage switch or leakage circuit breaker, is mainly used to protect against leakage faults in the equipment and to protect people from fatal electric shock. It has overload and short-circuit protection functions. It can be used to protect the line or motor from overload and short circuit. It can also be used as an infrequent switching start of the line under normal circumstances.
[0003] In practice, multiple circuit breakers are usually integrated into one unit, making it easier to adjust the system configuration according to changes in load demand. For example, in data centers, industrial facilities, or commercial buildings, as electricity demand grows, more circuit breaker modules can be simply added without replacing the entire power distribution system. Installing multiple circuit breakers in a centralized location can simplify the wiring and installation process, while making maintenance and troubleshooting more convenient. In addition, when a circuit breaker needs to be replaced or inspected, the relevant operations can be quickly located and performed without causing major interference to the entire system. In an environment with limited space, installing multiple circuit breakers together can save space and thus reduce the footprint, which is especially important for facilities with limited space. However, in practice, additional connectors are usually required to connect two circuit breakers together. Therefore, how to achieve convenient disassembly and assembly between circuit breakers has become a problem that needs to be urgently solved by technicians in this field. Summary of the invention

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0026] Such as Figures 1 - 7As shown, the utility model discloses a modular leakage circuit breaker, which is composed of a left circuit breaker body 1 and a right circuit breaker body 2. The length directions of the left circuit breaker body 1 and the right circuit breaker body 2 are extended up and down. The left side of the right circuit breaker body 2 is protrudingly provided with a positioning plug 21, and the right side of the left circuit breaker body 1 is provided with a positioning slot 11 corresponding to the positioning plug 21. The upper and lower sides of the left circuit breaker body 1 are rotatably installed with installation panels 12. The right circuit breaker body 2 is located at each installation panel 1 2 are provided with installation slots 22, each of the installation panels 12 is located in the corresponding installation slots 22 and is detachably connected to the right circuit breaker body 2 by means of buckles, bolts, etc., and a connecting plate 13 is slidably installed on the rear side of the left circuit breaker body 1, and the connecting plate 13 is detachably connected to the right circuit breaker body 2 by means of buckles, bolts, etc. 1. Since a positioning block 21 is protrudingly provided on the left side of the right circuit breaker body 2, after the positioning block 21 is inserted into the corresponding positioning slot 11, it can be completed at this time 1. The positions of the left circuit breaker body 1 and the right circuit breaker body 2 are relatively determined, thereby providing convenience for rotating the installation panel 12 and the sliding connecting plate 13; 2. Since the installation panel 12 is rotatably installed on the left circuit breaker body 1, the installation panel 12 is rotated and placed into the installation slot 22 to complete the connection with the right circuit breaker body 2, so that the front sides of the left circuit breaker body 1 and the right circuit breaker body 2 can be connected together. At this time, by moving the connecting plate 13 so that it reaches the right circuit breaker body 2 and then connects with the right circuit breaker body 2, the left circuit breaker body 1 and the right circuit breaker body 2 can be stably installed, thereby achieving the purpose of occupying less space when multiple circuit breakers are installed together, and as the power demand increases, more circuit breaker modules can be simply added without replacing the entire power distribution system; 3. Since the left circuit breaker body 1 and the right circuit breaker body 2 can be regarded as one module, more circuit breaker modules can be added by increasing the left circuit breaker body 1 and the right circuit breaker body 2.
[0027] Preferably, the positioning block 21 is arranged in a stepped shape with a narrow left side and a wide right side, and the positioning slot 11 is arranged in a cubic shape. Since the left side of the positioning block 21 is the narrowest, and when the left circuit breaker body 1 and the right circuit breaker body 2 are assembled together, the first part of the positioning block 21 that enters the positioning slot 11 is the left side of the positioning block 21. Therefore, the positioning block 21 arranged with a narrow left side and a wide right side can enter the positioning slot 11 more smoothly.
[0028] In addition, it also includes an adjusting screw 3. The left circuit breaker body 1 is located above the connecting plate 13 and is fixedly installed with an adjusting seat 14 by means of integral molding, welding, etc. The adjusting screw 3 is rotatably installed in the adjusting seat 14. The upper side of the connecting plate 13 is threadedly matched with the adjusting screw 3. Since the adjusting screw 3 is rotatably installed in the adjusting seat 14, the connecting plate 13 threadedly matched with the adjusting screw 3 can be moved by rotating the adjusting screw 3. Since the movement of the connecting plate 13 is driven by the rotation of the adjusting screw 3, the connecting plate 13 will not move arbitrarily on the left circuit breaker body 1 without the action of external force, thereby providing convenience for the connection and fixation of the connecting plate 13 and the right circuit breaker body 2.
[0029] Among them, the connecting plate 13 includes a guide section 131 below, and the left circuit breaker body 1 is provided with a guide seat 15 below the guide section 131. The guide seat 15 is provided with a track 151 for the guide section 131 to slide. Since the guide seat 15 provided on the left circuit breaker body 1 is provided with the track 151, when the adjusting screw 3 is rotated to drive the connecting plate 13 to move, the guide section 131 below the connecting plate 13 can be stably located in the track 151, so the track 151 can guide the moving path of the connecting plate 13.
[0030] The front side of the connecting plate 13 is hollow, and a plurality of positioning members 23 made of a deformable material such as rubber are protruding from the rear side of the right circuit breaker body 2. Each positioning member 23 includes a fixing section 231 and a limiting section 232. A fixing groove 132 for inserting the fixing section 231 is provided on the connecting plate 13. Each limiting section 232 abuts against the connecting plate 13. Since the limiting section 232 of each positioning member 23 abuts against the connecting plate 13, when the adjusting screw 3 is rotated to make the connecting plate 13 move to the right, a force is applied to the positioning member 23 that is easily deformed so that it moves toward the right circuit breaker body. 2 is close to each other, and thus will not affect the rightward movement of the connecting plate 13. When the positioning member 23 is located below the fixing groove 132, a force is applied to the limiting section 232 to force it to cross the fixing groove 132 and abut against the connecting plate 13. At this time, without the action of external force, the positioning member 23 is stably inserted into the connecting plate 13, so that the rear sides of the left circuit breaker body 1 and the right circuit breaker body 2 can be stably connected together. By bending the limiting section 232 to make it located in the length extension direction of the fixing section 231, and then bringing the positioning member 23 close to the right circuit breaker body 2, the connecting plate 13 can be moved to the left.
[0031] Preferably, each of the limiting sections 232 is inclined, and a mating groove 2321 is formed through each of the limiting sections 232. Since the limiting sections 232 are inclined, when the limiting sections 232 are forced to cross the fixing groove 132, the limiting sections 232 can be more smoothly aligned with the fixing groove 132 and cross the fixing groove 132. The provision of the mating groove 2321 enables the limiting sections 232 to be more easily stressed and bent when the limiting sections 232 are bent to force them to cross the fixing groove 132, thereby facilitating the insertion of the positioning member 23 into the connecting plate 13 or the separation from the connecting plate 13.
[0032] Wherein, a first magnet 121 is arranged at the rear side of the mounting panel 12, a second magnet 16 is arranged on the left circuit breaker body 1 corresponding to the first magnet 121, and a third magnet 24 is arranged on the right circuit breaker body 2 corresponding to the first magnet 121. 1. Since the first magnet 121 is arranged on the mounting panel 12 and the second magnet 16 is arranged on the left circuit breaker body 1, when it is not necessary to connect the left circuit breaker body 1 and the right circuit breaker body 2 together, at this time, the mounting panel 12 can be stably located on the left circuit breaker body 1 through the attraction of the first magnet 121 and the second magnet 16; 2. When it is necessary to connect the left circuit breaker body 1 and the right circuit breaker body 2 together, at this time, the mounting panel 12 is turned to the right, and the mounting panel 12 can enter the right circuit breaker body 2, so as to realize the attraction of the first magnet 121 and the third magnet 24, so that the mounting panel 12 rotatably mounted on the left circuit breaker body 1 can be located on the right circuit breaker body 2, thereby realizing the connection of the front sides of the left circuit breaker body 1 and the right circuit breaker body 2.
[0033] In addition, it further includes a bolt (not shown in the figure). A jack 122 is arranged on the mounting panel 12, a threaded hole 25 is arranged on the right circuit breaker body 2, and the bolt is inserted into the jack 122 and is in threaded cooperation with the threaded hole 25. Since the bolt can be inserted into the jack 122 on the mounting panel 12 and is in threaded cooperation with the threaded hole 25 on the right circuit breaker body 2, after the mounting panel 12 is turned to the right and the bolt is inserted, the mounting panel 12 can be stably located on the right circuit breaker body 2, thereby enabling the front sides of the left circuit breaker body 1 and the right circuit breaker body 2 to be stably connected together.
[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
