[0035] Among them, one end of the series rod 101 passes through the connecting groove 104 and sequentially penetrates multiple parallel opening and closing buttons 103 along the direction of the rotation axis 102 of the opening and closing buttons 103. The embodiment of the present application can ensure the stability of multiple opening and closing buttons 103 when closing the switch by setting the series rod 101, and ensure the consistency of their closing rotation action. Similarly, the embodiment of the present application can ensure the stability of multiple opening and closing buttons 103 when opening the switch by setting the series rod 101, and ensure the consistency of their opening rotation action.
[0036] It should be noted that in the embodiment of the present application, the multiple connection grooves 104 are located on the same straight line, that is, the extension directions of the multiple connection grooves 104 coincide with each other.
[0037] It should be noted that the specific shapes of the connecting groove 104 and the series rod 101 can be selected by those skilled in the art according to needs, and are not particularly limited in the embodiments of the present application.
[0038] Illustratively, the connection groove 104 in the embodiment of the present application may be a U-shaped groove or a T-shaped groove, and the serial rod 101 is a rod structure that is arranged in coordination with the connection groove 104 .

[0040] Illustratively, the cross-section of the connection groove 104 in the embodiment of the present application is polygonal, and the serial rod 101 is a polygonal rod passing through the connection groove 104 .
[0041] It should be noted that the series rod 101 of the embodiment of the present application can be pre-buried inside the circuit breaker 100, or can be set on the surface of the opening and closing button 103 of the circuit breaker 100. Those skilled in the art can set it according to specific needs.
[0042] It should be noted that the circuit breaker 100 provided in the embodiment of the present application is provided with at least two opening and closing buttons 103. The circuit breaker 100 may be a two-pole circuit breaker 100 (2P), a three-pole circuit breaker 100 (3P), or a four-pole circuit breaker 100 (4P).
[0043] According to the needs, the circuit breaker 100 of the embodiment of the present application can also be other multi-pole circuit breakers 100 with multiple opening and closing buttons 103. In this regard, those skilled in the art can select and set according to the needs.
[0044] A circuit breaker 100 provided in an embodiment of the present application includes a series rod 101 and a plurality of opening and closing buttons 103 which are arranged side by side in sequence and whose rotation axes 102 coincide with each other. In the embodiment of the present application, a connection groove 104 is preset on each opening and closing button 103, and the extension direction of the connection groove 104 is parallel to the rotation axis 102. In the embodiment of the present application, the series rod 101 is used to pass through the plurality of connection grooves 104 in sequence, and the series rod 101 is engaged with the connection groove 104.
[0045] Therefore, the circuit breaker 100 provided in the embodiment of the present application can ensure the consistency of the actions of multiple opening and closing buttons 103 during the rotation of the opening and closing buttons 103, and is suitable for conversion switches such as two-pole circuit breakers 100 (2P), three-level circuit breakers 100 (3P), and four-pole circuit breakers 100 (4P). The embodiment of the present application can effectively eliminate the inter-pole angle difference of the circuit breaker 100 during the closing operation, so that multiple opening and closing buttons 103 can be closed synchronously, ensuring that the closing action can be completed quickly.
[0046] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, as an optional implementation, the series rod 101 is arranged on the pressing surface 105 of the opening and closing button 103, and a protective cover 106 is arranged on the series rod 101, and the surface of the protective cover 106 is in contact with the pressing surface 105 of the opening and closing button 103.
[0047] In the embodiment of the present application, the series rod 101 is arranged on the pressing surface 105 of the opening and closing button 103, that is, the connecting groove 104 is arranged on the pressing surface 105. In the embodiment of the present application, a protective cover 106 is arranged on the pressing surface 105 to protect multiple opening and closing buttons 103 arranged side by side.
[0048] In addition, since the protective cover 106 is arranged in contact with the surfaces of the multiple opening and closing buttons 103, the consistency of the actions of the multiple opening and closing buttons 103 can be further enhanced, so that the inter-pole angle difference of the circuit breaker 100 during the closing operation can be effectively eliminated, which is beneficial for the staff to operate.
[0049] Reference Figure 5 As shown, as an optional implementation, an operating handle 107 is provided on the protective cover 106 , and one end of the operating handle 107 is vertically connected to the protective cover 106 .
[0050] When closing the circuit breaker, Figure 5 For example, the operating handle 107 is subjected to force to drive the protective cover 106 to rotate clockwise around the rotation axis 102, and the protective cover 106 simultaneously drives several opening and closing buttons 103 to rotate clockwise around the rotation axis 102, so that the multi-pole modules in the circuit breaker are closed at the same time, avoiding the situation of asynchronous closing, and can effectively eliminate the closing angle difference.
[0051] Similarly, when opening the gate, Figure 5 For example, the operating handle 107 is forced to drive the protective cover 106 to rotate counterclockwise, and the protective cover 106 drives a plurality of opening and closing buttons 103 to rotate around the rotation axis 102, so that the multi-pole modules in the circuit breaker are opened at the same time. Therefore, the embodiment of the present application can greatly improve the synchronization of opening and closing.
[0052] As an optional implementation, when the series rods 101 pass through the connection slots 104 in sequence, the protective cover 106 can be driven to slide from one side of the opening and closing button 103 to the pressing surface of the opening and closing button 103 .
[0053] Furthermore, the protective cover 106 of the embodiment of the present application is also provided with an operating handle 107. The embodiment of the present application can increase the operating force arm of the opening and closing button 103 through the provision of the operating handle 107, so that the opening and closing button 103 is easy to operate.
[0054] It should be noted that the operating handle 107 implemented in the present application is vertically arranged with the protective cover 106, which is convenient for the staff to operate by hand. The technicians in this field can also make the operating handle 107 and the protective cover 106 form a certain angle as needed.
[0055] Exemplarily, the extending direction of the operating handle 107 is set at an angle of 60° with the protective cover plate 106. Exemplarily, the extending direction of the operating handle 107 is set at an angle of 70° with the protective cover plate 106.
[0056] Reference Figure 5 As shown, the operating handle 107 can be fixed on the protective cover 106 by a connection assembly such as bolts, and the operating handle 107 can also be detachably connected to the protective cover 106 by a clamping assembly. Those skilled in the art can make settings as needed.
[0057] Exemplarily, a snap-fit assembly is disposed in the middle of the protective cover 106 , and the operating handle 107 is detachably connected to the protective cover 106 via the snap-fit assembly.
[0058] The snap-on assembly may be a snap-on strip disposed on the operating handle 107 , and connected to a slot disposed on the protective cover 106 via the snap-on strip.
[0059] Reference Figure 3 as well as Figure 5 As shown, as an optional implementation, it also includes a shell 108 for mounting the opening and closing button 103 , and the plane where the protective cover 106 is located is flush with the surface of the shell 108 .
[0060] The embodiment of the present application also includes a shell 108 for installing the opening and closing button 103, so that the covering plane of the protective cover 106 is flush with the surface of the shell 108, that is, the pressing plane of the opening and closing button 103 is slightly lower than the surface of the shell 108, ensuring that after the protective cover 106 is installed, the shell 108 of the circuit breaker 100 can have a flat outer side surface, which is beneficial to reducing the overall occupied space of the circuit breaker 100 and facilitating the assembly of the circuit breaker 100 in the distribution box.
[0061] It should be noted that the protective cover 106 covers the pressing surfaces 105 of the plurality of opening and closing buttons 103 along the direction of the rotation axis 102. That is to say, the area of the protective cover 106 is consistent with the area of the pressing surfaces 105 of the plurality of opening and closing buttons 103, so that the protective cover 106 can completely cover the pressing surfaces 105 of the plurality of opening and closing buttons 103, ensuring that the protective cover 106 can provide comprehensive protection.
[0062] As an optional implementation, the operating handle 107 is a T-shaped structural member, and a plurality of spaced-apart connectors are disposed at the upper end of the T-shaped structural member; a plurality of plug-in holes are disposed in the middle of the protective cover 106, and the connectors are correspondingly plugged into the plug-in holes.
[0063] There is a preset distance between the connection groove 104 and the pressing surface 105 of the opening and closing button 103 .
[0064] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, as an optional embodiment, the cross-section of the connecting groove 104 on the plane perpendicular to the rotation axis 102 is U-shaped, and the serial rod 101 is a U-shaped rod 109; or, the cross-section of the connecting groove 104 is T-shaped, and the serial rod 101 is a T-shaped rod 110.
[0065] Reference Figure 3 as well as Figure 4 As shown, as an optional implementation, two connection grooves 104 are provided on the opening and closing button 103 , and the two connection grooves 104 are located on both sides of the rotation axis 102 .
[0066] In the embodiment of the present application, a rotation axis 102 is provided on both sides of the rotation axis 102 of the opening and closing button 103, and two parallel series rods 101 can be inserted on the opening and closing button 103. Compared with one series rod 101, two series rods 101 can make up for the shaking caused by the matching gap between the series rod 101 and the connecting groove 104, and further enhance the consistency of the opening and closing actions.
[0067] In addition, the embodiments of the present application can also reduce the opening and closing force, making it easier for staff to operate.
[0068] Among them, refer to Figure 6As shown, the closing and opening button 103 is connected to the closing link 111, and one end of the closing link 111 is connected to the closing and opening button 103 and the other end is connected to the inner rotating handle 112. It should be noted that the button force arm formed by the line connecting the rotation axis 102 to the closing link 111 intersects the closing link 111 perpendicularly, and the inner handle force arm formed by the line connecting the rotation center of the inner rotating handle 112 to the closing link 111 also intersects the closing link 111 perpendicularly. The maximum button force arm and inner handle force arm can be obtained through the above arrangement, so that the operating force of the closing and opening button 103 can be effectively reduced.
[0069] Compared with the prior art, the circuit breaker 100 provided in the embodiment of the present application can ensure the consistency of the actions of multiple opening and closing buttons 103 during the rotation of the opening and closing buttons 103, and is suitable for conversion switches such as two-pole circuit breakers 100 (2P), three-level circuit breakers 100 (3P), and four-pole circuit breakers 100 (4P). The embodiment of the present application can effectively eliminate the inter-pole angle difference of the circuit breaker 100 during the closing operation, so that multiple opening and closing buttons 103 can be closed synchronously, ensuring that the closing action can be completed quickly.
[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
