[0066] like Figures 1 to 7 As shown, this embodiment provides a circuit breaker that is easy to disassemble, including a circuit breaker body 100. The circuit breaker body 100 is provided with a housing composed of a first housing 20, a second housing 30, and a third housing 40. The first housing 20 and the third housing 40 are integrally provided. A receiving cavity is provided in the housing for installing an electronic component 50.

[0067] The electronic component 50 is fixedly connected to the first shell 20 via a fastening connector 10 , and the first shell 20 and the second shell 30 are connected via a plug connector 501 , and the second shell 30 and the third shell 40 are connected via a snap connector 60 .

[0068] In this embodiment, the shells composed of the first shell 20, the second shell 30 and the third shell 40 are connected by fastening connectors 10 and snap-on connectors 60, which replace the existing screw installation. This makes disassembly simple, convenient for users to repair and replace, and improves the user experience.

[0069] See Figures 1 to 3As shown, the fastening connector 10 includes a sleeve 101, and the sleeve 101 is welded on the electronic component 50. A second positioning ring 106 is welded on the sleeve 101, and multiple groups of second magnets 107 are evenly distributed circumferentially on the second positioning ring 106. At least one group of holes 102 is opened in the sleeve 101, and movable beads are fixedly installed in the holes 102.

[0070] Furthermore, the fastening connector 10 further includes a connecting rod 104, and the connecting rod 104 passes through the first shell 20 and extends into the sleeve 101.

[0071] The connecting rod 104 is provided with at least one set of balls 105.

[0072] The connecting rod 104 is provided with a first positioning ring 103 , and the first positioning ring 103 and the connecting rod 104 are integrated.

[0073] Furthermore, first magnets 1031 are evenly distributed and installed in a circumferential direction on the first positioning ring 103 away from the connecting rod 104 , and the first magnets 1031 and the second magnets 107 are special-shaped magnets.

[0074] In this embodiment, when the first housing 20 is mounted on the electronic component 50, it is only necessary to snap the first housing 20 onto the electronic component. At this time, the connecting rod 104 provided on the first housing 20 extends into the sleeve 101. By rotating the connecting rod 104, the connecting rod 104 drives the ball to rotate. When the ball 105 contacts the outer wall of the movable ball, the connecting rod 104 is pushed until the first magnet 1031 and the second magnet 107 are attracted to each other, thereby achieving a fixed connection between the first housing and the electronic component.

[0075] When disassembly is required, the ball 105 contacts the outer wall of the movable ball, so when the connecting rod is pulled out of the sleeve 101, part of the resistance can be reduced, thereby improving convenience.

[0076] See Figures 1 to 3 As shown, a plug connector 501 is fixedly installed on the electronic component 50 by fastening screws. When the second shell is buckled, the elastic piece 5011 of the plug connector 501 is automatically inserted into the groove 302 set in the second shell 30, realizing the connection between the electronic component and the second shell.

[0077] Furthermore, the plug connector 501 is provided with an ear plate 5012. When the electronic component is connected to the second shell, the threaded hole of the ear plate 5012 is arranged corresponding to the threaded hole on the second shell, and a fastening bolt 301 is provided in the threaded hole for threaded connection.

[0078] In this embodiment, when installing the second shell, only one set of fastening bolts is required to achieve the installation of the second shell. The fastening bolts 301 are passed through the threaded holes on the second shell and the ear plate from the outside to the inside, and the fastening bolts are tightened at the same time. At this time, the elastic sheet 5011 on the plug-in connector 501 is automatically inserted into the groove body 302 of the second shell 30, thereby realizing the connection between the electronic components and the second shell.

[0079] In practical applications, in order to further enhance the fastening between the second shell and the third shell. Figure 1 、 Figure 5 As shown, a clamping seat 603 of the clamping connector 60 is welded on the second shell 30 near the third shell 40 , and two sets of oppositely arranged clamping ends 608 are provided in the cavity of the clamping seat 603 .

[0080] Furthermore, the snap-fit ​​connector 60 includes a push end portion 606 , and a screw 609 is provided on the push end portion 606 . The screw 609 passes through the push end portion 606 and is fixedly mounted with a push block.

[0081] Furthermore, a spring 605 is fixedly mounted on the pushing block away from the pushing end by a fastening screw, and the other end of the spring 605 is fixedly connected to the clamping block 604 .

[0082] Furthermore, a through slot 602 is provided on the clamping seat 603 away from the screw rod 609 , and the clamping block 604 passes through the through slot 602 , extends out of the clamping seat 603 , and is clamped into a clamping slot body provided on the third shell 40 .

[0083] Furthermore, the clamping block 604 extending out of the clamping seat 603 is bent to form an arc-shaped end 6013, and a clamping end 6011 is provided on the top end face of the arc-shaped end 6013, so that the arc-shaped end 6013 can be inserted into the clamping slot body, and the clamping end 6011 is engaged with the inverted groove in the clamping slot body, thereby facilitating the inverted installation of the plug-in connector in the third shell, thereby realizing the connection between the third shell 40 and the second shell.

[0084] The use process and working principle of this utility model:

[0085] When the utility model is in use, its specific installation process is as follows:

[0086] First, the first housing 20 is fastened to the outside of the electronic component. At this time, the connecting rod 104 provided on the first housing 20 extends into the sleeve 101. By rotating the connecting rod 104, the connecting rod 104 drives the ball to rotate. When the ball 105 contacts the outer wall of the movable ball, the connecting rod 104 is pushed until the first magnet 1031 and the second magnet 107 are attracted, thereby achieving a fixed connection between the first housing and the electronic component.

[0087] Then, the second housing 30 is fastened together. After fastening, the fastening bolts 301 are passed through the threaded holes on the second housing and the ear plate from the outside to the inside. At the same time, the fastening bolts are tightened. At this time, the elastic piece 5011 on the plug connector 501 is automatically inserted into the groove 302 of the second housing 30, thereby achieving the connection between the electronic component and the second housing.

[0088] At the same time, the arc-shaped end 6013 of the snap-fit ​​connector is inserted into the snap-fit ​​groove body, and the snap-fit ​​end 6011 is engaged with the inverted groove in the snap-fit ​​groove body, thereby facilitating the upside-down installation of the plug-in connector in the third shell; then the screw 609 is rotated, and the push end 606 is unscrewed by the screw, thereby driving the push block to move toward the position of the snap-fit ​​block 604, thereby compressing the spring 605. When disassembly is required, it is only necessary to reverse the screw 609 and drive the push block toward the push end through the screw, thereby releasing the restriction on the spring, and utilizing the elastic force of the spring to make the snap-fit ​​connector 60 bounce out of the snap-fit ​​groove body on the third shell 40.

[0089] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
