[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a detachable shell structure of a circuit breaker, including a circuit breaker body 1, with card boxes 2 fixedly connected to the upper and lower ends of the inner wall of the circuit breaker body 1, the inner wall of the card box 2 is clamped with a sealing plate 3, the left and right ends of the outer wall of the circuit breaker body 1 are clamped with a cover plate 4, and the front and rear ends of the outer wall of the cover plate 4 are clamped with the sealing plate 3.

[0028] In this embodiment, card boxes 2 are provided at the upper and lower ends of the inner wall of the circuit breaker body 1. When the circuit breaker needs to be disassembled and repaired, the sealing plate 3 provided on the front of the circuit breaker body 1 is removed to separate the sealing plate 3 from the limit of the card box 2. At this time, the cover plates 4 provided on the left and right ends of the outer wall of the circuit breaker body 1 are pulled to separate the cover plates 4 from the circuit breaker body 1. Then, the limiting plates 15 provided on one side of the circuit breaker body 1 are taken out, so that the electronic components in the circuit breaker body 1 are exposed, which is convenient for the operator to perform maintenance. This further solves the problem that when a traditional circuit breaker is damaged and needs maintenance, the outer shell is often fixed with screws, which makes the disassembly process very cumbersome, thereby resulting in low maintenance efficiency.

[0029] Example 2

[0030] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the upper and lower ends of the outer wall of the circuit breaker body 1 are fixedly connected with a connection box 5, a socket 6 is provided on the top of the connection box 5, and one end of the bottom of the inner wall of the connection box 5 is slidably connected with a moving block 7, and the left and right ends of the outer wall of the moving block 7 are fixedly connected with a shift block 8, and the left and right sides of the inner wall of the connection box 5 are fixedly connected with a limiting block 9, and the outer wall of the limiting block 9 is slidably connected to the end of the outer wall of the moving block 7 close to the shift block 8, and the end of the connection box 5 away from the moving block 7 is fixedly connected with a fixed block 10, and a groove 11 is provided on one side of the outer wall of the fixed block 10, and a terminal 12 is provided on the inner wall of the groove 11, and one end of the terminal 12 is overlapped with one side of the outer wall of the moving block 7.

[0031] In this embodiment, a connection box 5 is provided at the upper and lower ends of the outer wall of the circuit breaker body 1, and a socket 6 is provided at the top of the connection box 5. The terminal 12 is put on the wire interface, and then the wire is inserted into the socket 6 so that the wire socket is in the groove 11 provided on one side of the outer wall of the fixed block 10. At this time, the dial block 8 is dialed, and the movable block 7 provided at one end is used to push the movable block 7 along the limit block 9 in the connection box 5 toward the side of the fixed block 10. The movable block 7 is used to squeeze the terminal in the groove 11, so that the terminal 12 is deformed and the wire is firmly fixed, thereby completing the installation of the circuit breaker and the wire. When the circuit breaker is damaged, the dial block 8 is dialed to move the movable block 7 in the opposite direction of the fixed block 10, so that the terminal 12 wrapped with the wire is removed from the groove 11, thereby completing the disassembly of the circuit breaker. This further solves the problem that the traditional circuit breaker is cumbersome to operate during installation and disassembly, and it is difficult to quickly disassemble the circuit breaker for maintenance when a safety fault occurs.

[0032] Example 3

[0033] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, screw holes 13 are opened on the left and right ends of the front outer wall of the connecting box 5, and the inner wall of the screw hole 13 is threadedly connected with a screw 14, and one end of the screw 14 overlaps with one side of the outer wall of the moving block 7.

[0034] In this embodiment, screw holes 13 are provided at the left and right ends of the front outer wall of the connection box 5, and screws 14 are provided on the inner walls of the screw holes 13. By tightening the screws 14, one end of the screws 14 is brought into contact with the movable block 7, thereby limiting the movable block 7 by using the screws 14 to prevent the wires from loosening in the socket 6, thereby preventing unnecessary safety hazards.

[0035] Example 4

[0036] like Figure 1-5As shown, based on Example 1, the present invention provides a technical solution: preferably, the left and right ends of the inner wall of the circuit breaker body 1 are clamped with limit plates 15, and one side of the limit plate 15 is clamped with one side of the outer wall of the cover plate 4.

[0037] In this embodiment, by providing limit plates 15 at the left and right ends of the inner wall of the circuit breaker body 1, the limit plates 15 are used to support the electronic components inside the circuit breaker body 1. When the circuit breaker is damaged and its internal electronic components need to be repaired, the limit plates 15 on both sides are removed, thereby facilitating the replacement of individual electronic components inside the circuit breaker.

[0038] The following is a detailed description of the working principle of the detachable housing structure of the circuit breaker.

[0039] like Figure 1-5As shown, by setting a connection box 5 at the upper and lower ends of the outer wall of the circuit breaker body 1, a socket 6 is set on the top of the connection box 5, the terminal 12 is put on the wire interface, and then the wire is inserted into the socket 6, so that the wire socket is in the groove 11 set on one side of the outer wall of the fixed block 10. At this time, the dial block 8 is dialed, and the dial block 8 is used to push the moving block 7 set at one end thereof, so that the moving block 7 moves along the limit block 9 in the connection box 5 toward the side of the fixed block 10, and the moving block 7 is used to squeeze the terminal in the groove 11, so that the terminal 12 is deformed and the wire is firmly fixed, thereby completing the circuit breaker. When the circuit breaker is damaged, the dial block 8 is toggled to move the movable block 7 in the opposite direction of the fixed block 10, so that the terminal 12 wrapped with the wire is removed from the threshing groove 11, thereby completing the disassembly of the circuit breaker, further solving the problem that the traditional circuit breaker is complicated to operate during installation and disassembly, and it is difficult to quickly disassemble the circuit breaker for maintenance when a safety fault occurs. By setting screw holes 13 at the left and right ends of the front side of the outer wall of the connection box 5, and setting screws 14 on the inner wall of the screw holes 13, by tightening the screws 14, one end of the screw 14 is fixed to the movable block 10. 7 is in contact, thereby using screws 14 to limit the moving block 7 to prevent the wires from loosening in the socket 6, thereby causing unnecessary safety hazards. By setting card boxes 2 at the upper and lower ends of the inner wall of the circuit breaker body 1, when the circuit breaker needs to be disassembled and repaired, the sealing plate 3 set on the front of the circuit breaker body 1 is removed to separate the sealing plate 3 from the limit of the card box 2. At this time, the cover plates 4 set on the left and right ends of the outer wall of the circuit breaker body 1 are pulled to separate the cover plates 4 from the circuit breaker body 1. Then, the limiting plate 15 set on one side of the circuit breaker body 1 is taken out, so that the electronic components in the circuit breaker body 1 are exposed. It is convenient for operators to carry out maintenance, and further solves the problem that when a traditional circuit breaker is damaged and needs maintenance, the shell is often fixed with screws, which makes the disassembly process very cumbersome and causes low maintenance efficiency. By arranging limit plates 15 at the left and right ends of the inner wall of the circuit breaker body 1, the limit plates 15 are used to support the electronic components in the circuit breaker body 1. When the circuit breaker is damaged and its internal electronic components need to be repaired, the limit plates 15 on both sides are removed, thereby facilitating the replacement of a single electronic component in the circuit breaker.

[0040] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
