Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a miniature circuit breaker which is easy to disassemble. Background Art

[0002] Miniature circuit breakers are the most widely used terminal protection devices in building electrical terminal distribution devices. They are used for single-phase and three-phase short circuit, overload, overvoltage and other protection below 125A. There are four types: single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P. Circuit breakers need to be installed in designated locations during use. If used for a long time, the circuit breakers need to be inspected and maintained regularly.

[0003] However, the existing circuit breaker has a weak fixing function, and the circuit breaker is not installed stably during use, which can easily cause the circuit breaker to move during use, thereby affecting the normal operation of the circuit breaker and posing certain safety hazards. In addition, the maintenance effect of the existing circuit breaker is poor. The maintenance process of the circuit breaker is relatively cumbersome when used for a long time. When the circuit breaker fails and needs to be replaced, the disassembly steps are relatively cumbersome, which affects the maintenance efficiency. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A miniature circuit breaker that is easy to disassemble includes a fixing plate, a mounting groove is provided in the middle of the fixing plate surface, limit grooves are provided on both sides of the inner wall of the mounting groove, a connecting component is movably connected inside the limit groove, one side of the connecting component is fixedly connected to the circuit breaker body, and a plurality of limit holes are provided on both sides of the fixing plate surface, an elastic component is fixedly connected inside the limit holes, and one end of the elastic component is fixedly connected to the limit plate.

[0007] Preferably, the connecting assembly includes a connecting plate, the middle parts of both sides of the connecting plate are slidably connected to the inside of the limit groove, the surface of the connecting plate is fixedly connected to a rectangular plate, one side of the top of the rectangular plate is fixedly connected to a baffle, and the surface of the rectangular plate is fixedly connected to one side of the circuit breaker body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides an elastic component. During the installation process, the rectangular plate will squeeze the limit plate. When the limit plate is squeezed, it approaches the fixed plate, thereby squeezing the limit springs in the multiple limit holes on the fixed plate, so that the limit springs are retracted into the limit holes on the fixed plate under the cooperation of the hollow column and the extension column. When the installation is completed, the limit spring begins to rebound under the action of the reaction force. Under the cooperation of the hollow column and the extension column, the limit plate is driven to be close to the rectangular plate, thereby applying pressure to the rectangular plate and fixing the position of the circuit breaker body, thereby achieving the effect of enhancing the stability of the device.

[0014] 2. The utility model is provided with a connection assembly. When in use, the fixing plate can be installed in a suitable position using fixing bolts, and then the connecting plate on the rectangular plate is inserted into the installation groove on the fixing plate to install the circuit breaker body.

Through the arrangement of the elastic component 5, during use and installation, the rectangular plate 402 will squeeze the limiting plate 6. When the limiting plate 6 is squeezed, it approaches the fixed plate 1, thereby squeezing the limiting springs 502 in the multiple limiting holes on the fixed plate 1, so that the limiting springs 502 are retracted into the limiting holes on the fixed plate 1 under the cooperation of the hollow column 501 and the extension column 503. When the installation is completed, the limiting spring 502 begins to rebound under the action of the reaction force. Under the cooperation of the hollow column 501 and the extension column 503, the limiting plate 6 is driven to be close to the rectangular plate 402, thereby applying pressure to the rectangular plate 402, fixing the position of the circuit breaker body 7, and achieving the effect of enhancing the stability of the device.
