Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and particularly to an electrical switch. Background Art

[0002] An electrical switch is a device used to control the on / off of a circuit. As a type of electrical switch, a circuit breaker can not only connect, carry, and disconnect current under normal conditions, but also automatically cut off the current when abnormal conditions such as overload or short circuit occur in the circuit to protect the circuit and electrical equipment.

[0003] Generally, a circuit breaker needs to be installed on a rail in a distribution box or a power distribution cabinet through an installation structure installed at its bottom. However, the installation structure in the related art is not reasonably designed and is not convenient for realizing the miniaturization of the circuit breaker. Summary of the Utility Model

[0004] This application provides an electrical switch, which can realize the miniaturization of the circuit breaker while ensuring that the electrical switch can be installed on the rail.

[0005] In a first aspect, this application provides an electrical switch, which includes a housing and an elastic member. The housing is provided with a rail groove and a sliding groove, and the sliding groove is communicated with the rail groove. The rail groove is used to accommodate the rail. The elastic member is installed in the sliding groove. The elastic member includes a first end and a second end that are opposite in position. The first end can abut against the rail to install the electrical switch on the rail. Among them, the second end does not protrude from the side of the sliding groove away from the rail groove.

[0006] Through the above solution, the second end of the elastic member can be entirely located within the sliding groove, or the second end of the elastic member can be flush with the side of the sliding groove away from the rail groove. In this way, the overall size of the circuit breaker will not increase due to the arrangement of the elastic member, which is convenient for realizing the miniaturization of the circuit breaker while ensuring that the electrical switch can be installed on the rail.

[0007] In a possible design, the elastic member includes a first elastic arm, a second elastic arm, and a third elastic arm that are connected. The first elastic arm and the second elastic arm are located on both sides of the third elastic arm. The connection part of the first elastic arm, the second elastic arm, and the third elastic arm forms the second end of the elastic member, and the first end is the end of the third elastic arm away from the second end. The groove wall of the sliding groove is provided with a first limiting wall and a second limiting wall. The part of the first elastic arm away from the second end abuts against the first limiting wall, and the part of the second elastic arm away from the second end abuts against the second limiting wall. The first limiting wall and the second limiting wall are used to limit the movement of the elastic member in the direction from the rail groove to the sliding groove.

[0008] Through the above solution, the first limiting wall and the second limiting wall can restrict the movement of the elastic member in the direction from the guide rail groove to the sliding groove. In this way, the elastic member will not move excessively in the direction from the guide rail groove to the sliding groove under the action of an external force, reducing the possibility that the second end of the elastic member is exposed outside the housing, and preventing the second end of the elastic member from protruding from the side of the sliding groove away from the guide rail groove, thus facilitating the miniaturization of the circuit breaker.

[0009] In a possible design, a protrusion is provided on the first groove wall of the guide rail groove. There is a gap between the protrusion and the groove bottom of the guide rail groove, and the gap communicates the guide rail groove with the sliding groove; a slot is provided on the second groove wall of the guide rail groove. When the electrical switch is installed on the guide rail, the abutting end of the guide rail is snapped into the gap and abuts against the first end, and the clamping end of the guide rail is snapped into the slot. Among them, the first groove wall is the groove wall of the guide rail groove close to the sliding groove, the second groove wall is the groove wall of the guide rail groove far from the sliding groove, the abutting end of the guide rail is the end of the guide rail close to the elastic member, and the clamping end of the guide rail is the end of the guide rail far from the elastic member.

[0010] Through the above solution, when installing the electrical switch on the guide rail, only need to snap the abutting end of the guide rail into the gap and abut against the first end of the elastic member, and then snap the clamping end of the guide rail into the slot, then the installation of the electrical switch on the guide rail can be realized. The installation steps are simple, which is convenient for improving the installation efficiency of the electrical switch on the guide rail.

[0011] In a possible design, when the housing moves in the direction from the sliding groove to the guide rail groove, the abutting end pushes against the first end, so that the first end drives the elastic member to move in the direction from the guide rail groove to the sliding groove. When the first end drives the elastic member to move in the direction from the guide rail groove to the sliding groove, the slot can release the restriction on the clamping end, so that the electrical switch can be detached from the guide rail.

[0012] Through the above solution, the electrical switch can be detached from the guide rail without using tools in this application, and the disassembly efficiency is relatively high.

[0013] In a possible design, the protrusion includes a first limiting surface. When the abutting end pushes against the first end to release the restriction of the slot on the clamping end, the guide rail can abut against the first limiting surface, and the first limiting surface is used to restrict the movement of the housing relative to the guide rail in the direction from the sliding groove to the guide rail groove.

[0014] In a possible design, when the abutting end pushes against the first end to release the restriction of the slot on the clamping end, the guide rail abuts against the first groove wall, and the first groove wall is used to restrict the movement of the housing relative to the guide rail in the direction from the sliding groove to the guide rail groove.

[0015] Through the above solution, on the one hand, it can prevent the abutting end from continuously pushing the first end along the direction of the guide rail groove to the sliding groove, so that the spring provided between the third elastic arm and the housing is excessively compressed, reducing the possibility of damage to the spring. On the other hand, when the elastic member moves along the direction of the guide rail groove to the sliding groove, the first elastic arm and the second elastic arm will deform and approach each other. Through the abutting relationship between the guide rail and the first limiting surface, or through the abutting relationship between the guide rail and the first groove wall, it can prevent the first elastic arm and the second elastic arm from deforming excessively, thereby reducing the possibility of the first elastic arm detaching from the first limiting wall and reducing the possibility of the second elastic arm detaching from the second limiting wall. On the other hand, it can avoid the elastic member from moving excessively along the direction of the guide rail groove to the sliding groove, reducing the possibility of the elastic member slipping out of the sliding groove and also reducing the possibility of the second end of the elastic member protruding from the side of the sliding groove away from the guide rail groove.

[0016] In a possible design, a second limiting surface is provided on the side of the convex block facing the sliding groove. When the elastic member is installed in the sliding groove, the first end abuts against the second limiting surface.

[0017] Through the above solution, it can limit the movement of the first end along the direction of the sliding groove to the guide rail groove, reducing the possibility of the elastic member slipping out of the sliding groove. In addition, the first end of the elastic member abuts against the second limiting surface, which can be used as a basis for the elastic member to be installed in place in the sliding groove, facilitating the guiding of the installation of the elastic member in the sliding groove.

[0018] In a possible design, the housing is further provided with a tool groove, and the tool groove communicates with the sliding groove. The tool groove is used for inserting a tool to pinch the first elastic arm and the second elastic arm together through the tool.

[0019] By inserting the tool into the tool groove and pinching the first elastic arm and the second elastic arm together, it can reduce the possibility that the first elastic arm gets stuck with the first groove wall and cannot continue to move along the direction of the sliding groove to the guide rail groove, and it can also reduce the possibility that the second elastic arm gets stuck with the second groove wall and cannot continue to move along the direction of the sliding groove to the guide rail groove. Therefore, it is convenient for the first elastic arm and the second elastic arm to smoothly move into the space between the first limiting wall and the second limiting wall to be installed in place, improving the installation efficiency of the elastic member into the sliding groove.

[0020] In a possible design, a first arc surface is provided at a position of the first elastic arm away from the second end, and the first arc surface abuts against the first limiting wall. And / or, a second arc surface is provided at a position of the second elastic arm away from the second end, and the second arc surface abuts against the second limiting wall.

[0021] Through the above solution, the part of the first elastic arm for abutting against the first limiting wall is not too angular, which can reduce the possibility of mutual wear between the part of the first elastic arm far from the second end and the first arc surface during relative movement, so that the first elastic arm can maintain a good abutting relationship with the first limiting wall, and the first limiting wall can better play its limiting role. Similarly, the part of the second elastic arm for abutting against the second limiting wall is not too angular, which can reduce the possibility of mutual wear between the part of the second elastic arm far from the second end and the second arc surface during relative movement, so that the second elastic arm can maintain a good abutting relationship with the second limiting wall, and the second limiting wall can better play its limiting role.

[0022] In a possible design, the electrical switch is a contactor or a circuit breaker. Description of the Drawings

[0044] A circuit breaker is an important switching device in a power mechanism and can close, carry and interrupt the current in a circuit. Among them, a miniature circuit breaker is a common terminal protection electrical appliance in the field of low-voltage electrical appliances, with a large quantity and wide range. At present, the installation structure of a miniature circuit breaker basically adopts a clip structure, and the circuit breaker is installed on a rail through the clip structure.

[0045] After the clip structure in the related art is installed on the rail, the clip structure often partially protrudes from the housing of the circuit breaker, making the overall size of the circuit breaker larger and not facilitating the miniaturization of the circuit breaker.

[0046] In view of this, the present application provides an electrical switch to facilitate the miniaturization of the circuit breaker while ensuring that the electrical switch can be installed on the rail.

[0047] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0048] Figure 1 It is a schematic structural diagram of an electrical switch installed on a rail provided in an embodiment of this application. Figure 2 It is a schematic assembly structure diagram of an electrical switch provided in an embodiment of this application. Figure 3 It is an exploded view of an electrical switch provided in an embodiment of this application. As Figures 1 to 3 shown, this application provides an electrical switch 100. Among them, the electrical switch 100 can be a contactor or a circuit breaker. In the following, this application will take the electrical switch 100 as a circuit breaker as an example for introduction.

[0049] As Figures 1 to 3 shown, the electrical switch 100 provided in this application includes a housing 110 and an elastic member 120. The housing 110 is provided with a rail groove 111 and a chute 112. The chute 112 communicates with the rail groove 111, and the rail groove 111 is used to accommodate the rail 200. The elastic member 120 is installed in the chute 112. The elastic member 120 includes a first end 121 and a second end 122 that are opposite in position. The first end 121 can abut against the rail 200 to install the electrical switch 100 on the rail 200. Among them, the second end 122 does not protrude from the side of the chute 112 away from the rail groove 111.

[0050] The housing 110 includes a top and a bottom that are opposite in position. Generally, the top is used to arrange structures such as a handle and an indicator window, and the bottom is used to arrange structures such as the chute 112 and the rail groove 111. The rail groove 111 and the chute 112 of this application are both provided at the bottom of the housing 110.

[0051] The housing 110 includes a base 113 and an upper cover 114 that are covered and connected to each other. Based on this, a part of the chute 112 and the rail groove 111 can be provided on the base 113, and another part of the chute 112 and the rail groove 111 can be provided on the upper cover 114.

[0052] The rail groove 111 and the chute 112 can be substantially perpendicular. The chute 112 communicates with the rail groove 111. Therefore, the elastic member 120 located in the chute 112 can move along the direction from the chute 112 to the rail groove 111 to abut against the rail 200 in the rail groove 111, so that the electrical switch 100 is installed on the rail 200. And, the elastic member 120 can also move along the direction from the rail groove 111 to the chute 112 to release the abutment against the rail 200, so that the electrical switch 100 can be detached from the rail 200.

[0053] The elastic member 120 can be installed in the chute 112 along the direction from the chute 112 to the guide rail groove 111. When the elastic member 120 is installed in the chute 112, the first end 121 of the elastic member 120 enters the chute 112 first, and the first end 121 is also the end of the elastic member 120 for abutting against the guide rail 200. The second end 122 of the elastic member 120 is the end of the elastic member 120 far from the guide rail groove 111.

[0054] The second end 122 of the elastic member 120 may not protrude from the side of the chute 112 far from the guide rail groove 111 in at least one of the following three cases.

[0055] The first case is that the elastic member 120 is installed in the chute 112 and the electrical switch 100 is not installed on the guide rail 200.

[0056] The second case is that the electrical switch 100 is installed on the guide rail 200 and the first end 121 of the elastic member 120 abuts against the guide rail 200.

[0057] The third case is that during the installation of the electrical switch 100 on the guide rail 200, the guide rail 200 pushes against the first end 121 of the elastic member 120.

[0058] In the embodiment of the present application, the elastic member 120 is installed in the chute 112, and the first end 121 of the elastic member 120 can abut against the guide rail 200 so that the electrical switch 100 is installed on the guide rail 200. Among them, the second end 122 of the elastic member 120 does not protrude from the side of the chute 112 far from the guide rail groove 111, so that the second end 122 of the elastic member 120 can be entirely located in the chute 112, or the second end 122 of the elastic member 120 can be flush with the side of the chute 112 far from the guide rail groove 111. In this way, the overall size of the circuit breaker will not increase due to the installation of the elastic member 120, which is convenient for realizing the miniaturization of the circuit breaker while ensuring that the electrical switch 100 can be installed on the guide rail 200.

[0059] Figure 4 As shown in the structural schematic diagram of an elastic member provided by the embodiment of the present application, Figure 4 as shown, the elastic member 120 may include a first elastic arm 123, a second elastic arm 124 and a third elastic arm 125 that are connected to each other. The first elastic arm 123 and the second elastic arm 124 are located on both sides of the third elastic arm 125. The connection part of the first elastic arm 123, the second elastic arm 124 and the third elastic arm 125 forms the second end 122 of the elastic member 120, and the first end 121 is the end of the third elastic arm 125 far from the second end 122.

[0060] Figure 5 For Figure 3 the enlarged view of part A in Figure 5As shown, a first limiting wall 1121 and a second limiting wall (not shown in the figure) are provided on the groove wall of the sliding groove 112. Combining Figures 2 to 5 , the part of the first elastic arm 123 away from the second end 122 abuts against the first limiting wall 1121, and the part of the second elastic arm 124 away from the second end 122 abuts against the second limiting wall. The first limiting wall 1121 and the second limiting wall are used to limit the movement of the elastic member 120 in the direction from the guide groove 111 to the sliding groove 112.

[0061] The structures of the first elastic arm 123 and the second elastic arm 124 may be the same. The first elastic arm 123 and the second elastic arm 124 may be symmetrically arranged on both sides of the third elastic arm 125.

[0062] The first elastic arm 123, the second elastic arm 124 and the third elastic arm 125 may be separately formed and then assembled by means of bonding, clamping or plugging to form the elastic member 120. Alternatively, the first elastic arm 123, the second elastic arm 124 and the third elastic arm 125 may be integrally formed to form the elastic member 120. The embodiment of the present application does not limit the forming method of the elastic member 120.

[0063] The sliding groove 112 includes two groove walls opposite in position, and these two groove walls are arranged along the width direction of the sliding groove 112. Wherein, the width direction of the sliding groove 112 is perpendicular to the direction from the sliding groove 112 to the guide groove 111. The first limiting wall 1121 may be provided on one of the two groove walls, and the second limiting wall may be provided on the other of the two groove walls.

[0064] The first limiting wall 1121 and the second limiting wall may be inclined with respect to the direction from the sliding groove 112 to the guide groove 111. And, along the direction from the sliding groove 112 to the guide groove 111, the distance between the first limiting wall 1121 and the second limiting wall increases. With such a setting, when the elastic member 120 moves in the direction from the guide groove 111 to the sliding groove 112, the first limiting wall 1121 can limit the movement of the first elastic arm 123, and the second limiting wall can limit the movement of the second elastic arm 124, so as to facilitate limiting the movement of the elastic member 120 in the direction from the guide groove 111 to the sliding groove 112 through the first limiting wall 1121 and the second limiting wall.

[0065] After the elastic member 120 is installed in the chute 112, during the process of installing the electrical switch 100 onto the guide rail 200 or during the process of detaching the electrical switch 100 from the guide rail 200, the portion of the first elastic arm 123 away from the second end 122 always abuts against the first limiting wall 1121, and the portion of the second elastic arm 124 away from the second end 122 always abuts against the second limiting wall. In this way, it can be better ensured that the first limiting wall 1121 and the second limiting wall play a role in restricting the movement of the elastic member 120 along the direction from the guide rail groove 111 to the chute 112.

[0066] Exemplarily, in some embodiments, in combination with Figure 4 and Figure 5 , a first arc surface 1231 may be provided at the portion of the first elastic arm 123 away from the second end 122, and the first arc surface 1231 abuts against the first limiting wall 1121.

[0067] The first arc surface 1231 may be an arc chamfer provided at the portion of the first elastic arm 123 away from the second end 122.

[0068] Through the above settings, the portion of the first elastic arm 123 for abutting against the first limiting wall 1121 is not too angular. Compared with the straight chamfer at the portion of the first elastic arm 123 away from the second end 122, when the portion of the first elastic arm 123 away from the second end 122 moves relative to the first arc surface 1231, the possibility of mutual wear between the first elastic arm 123 and the first limiting wall 1121 can be reduced. When the wear between the first elastic arm 123 and the first limiting wall 1121 is reduced, the first elastic arm 123 can maintain a good abutting relationship with the first limiting wall 1121, and the first limiting wall 1121 can better play its limiting role.

[0069] Similarly, in some other embodiments, in combination with Figure 4 and Figure 5 , a second arc surface 1241 may be provided at the portion of the second elastic arm 124 away from the second end 122, and the second arc surface 1241 abuts against the second limiting wall.

[0070] Through the above settings, the portion of the second elastic arm 124 for abutting against the second limiting wall is not too angular. Compared with the straight chamfer at the portion of the second elastic arm 124 away from the second end 122, when the portion of the second elastic arm 124 away from the second end 122 moves relative to the second arc surface 1241, the possibility of mutual wear between the second elastic arm 124 and the second limiting wall can be reduced. When the wear between the second elastic arm 124 and the second limiting wall is reduced, the second elastic arm 124 can maintain a good abutting relationship with the second limiting wall, and the second limiting wall can better play its limiting role.

[0071] It should be noted that in the embodiment of the present application, only the portion of the first elastic arm 123 away from the second end 122 may be provided with a first arc surface 1231, and the first arc surface 1231 abuts against the first limiting wall 1121. Alternatively, only the portion of the second elastic arm 124 away from the second end 122 may be provided with a second arc surface 1241, and the second arc surface 1241 abuts against the second limiting wall. Alternatively, a first arc surface 1231 may be provided at the portion of the first elastic arm 123 away from the second end 122, and a second arc surface 1241 may be provided at the portion of the second elastic arm 124 away from the second end 122, and the first arc surface 1231 abuts against the first limiting wall 1121, and the second arc surface 1241 abuts against the second limiting wall.

[0072] In summary, a first limiting wall 1121 and a second limiting wall are provided on the groove wall of the sliding groove 112. The portion of the first elastic arm 123 away from the second end 122 abuts against the first limiting wall 1121, and the portion of the second elastic arm 124 away from the second end 122 abuts against the second limiting wall, so that the first limiting wall 1121 and the second limiting wall can limit the movement of the elastic member 120 in the direction from the guide groove 111 to the sliding groove 112. In this way, the elastic member 120 will not move excessively in the direction from the guide groove 111 to the sliding groove 112 under the action of an external force, reducing the possibility that the second end 122 of the elastic member 120 is exposed outside the housing 110, so that the second end 122 of the elastic member 120 will not protrude from the side of the sliding groove 112 away from the guide groove 111, thereby facilitating the miniaturization of the circuit breaker.

[0073] Figure 6 A front view of a housing provided by an embodiment of the application, in combination with Figure 3 and Figure 6 , in some embodiments, a convex block 1111 may be provided on the first groove wall 1114 of the guide groove 111. There is a gap 1112 between the convex block 1111 and the groove bottom of the guide groove 111, and the gap 1112 communicates the guide groove 111 with the sliding groove 112. A slot 1113 is provided on the second groove wall of the guide groove 111.

[0074] In combination with Figure 1 、 Figure 3 and Figure 6 , when the electrical switch 100 is installed on the guide rail 200, the abutting end 210 of the guide rail 200 is snapped into the gap 1112 and abuts against the first end 121, and the clamping end 220 of the guide rail 200 is snapped into the slot 1113.

[0075] In the direction from the sliding groove 112 to the guide groove 111, the guide rail 200 includes an abutting end 210 and a clamping end 220 that are opposite in position. Among them, the abutting end 210 is the end of the guide rail 200 close to the elastic member 120, and the clamping end 220 is the end of the guide rail 200 away from the elastic member 120.

[0076] In the direction from the sliding groove 112 to the guide rail groove 111, the guide rail groove 111 includes a first groove wall 1114 and a second groove wall that are opposite in position. Among them, the first groove wall 1114 is the groove wall of the guide rail groove 111 close to the sliding groove 112. In other words, the first groove wall 1114 is closer to the sliding groove 112 relative to the second groove wall. The second groove wall is the groove wall of the guide rail groove 111 far from the sliding groove 112. In other words, the second groove wall is far from the sliding groove 112 relative to the first groove wall 1114.

[0077] The guide rail groove 111 further includes a groove bottom, and the groove bottom is connected between the first groove wall 1114 and the second groove wall.

[0078] In the thickness direction of the guide rail 200, the size of the gap 1112 between the bump 1111 and the groove bottom of the guide rail groove 111 can be set according to the thickness of the guide rail 200. Exemplarily, the gap 1112 can be slightly larger than the thickness of the guide rail 200 to ensure that the abutting end 210 of the guide rail 200 can just be snapped into the gap 1112.

[0079] The slot 1113 can be a groove provided on the second groove wall. The position of the slot 1113 is opposite to the position of the aforementioned gap 1112, so that when the abutting end 210 of the guide rail 200 is snapped into the gap 1112 and abuts against the first end 121 of the elastic member 120, the clamping end 220 of the guide rail 200 can be smoothly snapped into the slot 1113.

[0080] In this embodiment, the first groove wall 1114 of the guide rail groove 111 is provided with a bump 1111, a gap 1112 is provided between the bump 1111 and the groove bottom of the guide rail groove 111, and the second groove wall of the guide rail groove 111 is provided with a slot 1113. With such a setting, when installing the electrical switch 100 onto the guide rail 200, only need to snap the abutting end 210 of the guide rail 200 into the gap 1112 and abut against the first end 121 of the elastic member 120, and then snap the clamping end 220 of the guide rail 200 into the slot 1113, then the installation of the electrical switch 100 on the guide rail 200 can be achieved. The installation steps are simple and facilitate improving the installation efficiency of the electrical switch 100 onto the guide rail 200.

[0081] Among them, a spring (not shown in the figure) can be provided between the third elastic arm 125 and the housing 110. One end of the spring abuts against the third elastic arm 125, and the other end of the spring abuts against the housing 110. When the abutting end 210 of the guide rail 200 is snapped into the gap 1112 and abuts against the first end 121 of the elastic member 120, the abutting end 210 applies an abutting thrust to the first end 121, causing the first end 121 to drive the elastic member 120 to move in the direction from the guide rail groove 111 to the sliding groove 112, and compressing the spring to store energy.

[0082] After the clamping end 220 is snapped into the slot 1113, the spring releases elastic force. Under the action of this elastic force, the entire electrical switch 100 moves along the chute 112 towards the guide rail groove 111, so that the first end 121 of the elastic member 120 and the slot 1113 clamp the guide rail 200, realizing the installation of the electrical switch 100 on the guide rail 200.

[0083] The above is the entire process of installing the electrical switch 100 onto the guide rail 200 in this application, and no tools are required during the installation process. Next, the process of disassembling the electrical switch 100 from the guide rail 200 in this application, as well as the related structures involved in the disassembly process, will be introduced in detail.

[0084] Similar to the sequence of installing the electrical switch 100 onto the guide rail 200, when disassembling the electrical switch 100 from the guide rail 200 in this application, first release the abutment between the elastic member 120 and the abutting end 210, and then release the abutment between the slot 1113 and the clamping end 220.

[0085] Exemplarily, when the housing 110 moves relative to the guide rail 200 along the chute 112 towards the guide rail groove 111, the abutting end 210 pushes against the first end 121, causing the first end 121 to drive the elastic member 120 to move along the guide rail groove 111 towards the chute 112. When the first end 121 drives the elastic member 120 to move along the guide rail groove 111 towards the chute 112, the slot 1113 can release the restriction on the clamping end 220, so that the electrical switch 100 can be disassembled from the guide rail 200.

[0086] When the housing 110 moves relative to the guide rail 200 along the chute 112 towards the guide rail groove 111, causing the first end 121 to drive the elastic member 120 to move along the guide rail groove 111 towards the chute 112, relative movement occurs between the guide rail 200 and the slot 1113, enabling the slot 1113 to be misaligned with the clamping end 220 of the guide rail 200. When the slot 1113 is completely misaligned with the clamping end 220 of the guide rail 200, the slot 1113 releases the restriction on the clamping end 220. At this time, by pulling the electrical switch 100 in a direction away from the guide rail 200, the electrical switch 100 can be disassembled from the guide rail 200.

[0087] It can be seen that in this application, the electrical switch 100 can be disassembled from the guide rail 200 without the aid of tools, and the disassembly efficiency is relatively high. Also, precisely because this application does not require tools for disassembly, it is not necessary, as in the prior art, to have a part of the second end 122 of the elastic member 120 protruding from the housing 110 to provide a tool insertion port for a tool used to pry the elastic member 120 outwards. Therefore, this application can reduce the difficulty of disassembling the electrical switch 100 from the guide rail 200 and improve the disassembly efficiency of the electrical switch 100 from the guide rail 200 while not increasing the overall volume of the electrical switch 100.

[0088] Further, in some embodiments, as Figure 6 shown, the bump 1111 may include a first limiting surface M1. In combination with Figure 1 , Figure 3 and Figure 6 , when the abutting end 210 abuts and pushes the first end 121 to release the restriction of the slot 1113 on the clamping end 220, the guide rail 200 can abut against the first limiting surface M1, and the first limiting surface M1 is used to limit the movement of the housing 110 relative to the guide rail 200 in the direction from the chute 112 to the guide rail groove 111.

[0089] The first limiting surface M1 may be a surface of the bump 1111 facing the slot 1113. The first limiting surface M1 may be a flat surface so as to increase the abutting area between the first limiting surface M1 and the guide rail 200.

[0090] As Figure 1 shown, the guide rail 200 may be in a "C" shape. The portion of the guide rail 200 close to the abutting end 210 includes an abutting surface substantially parallel to the first limiting surface M1. When the abutting end 210 abuts and pushes the first end 121 to release the restriction of the slot 1113 on the clamping end 220, the abutting surface of the guide rail 200 can exactly abut against the first limiting surface M1. In this way, the abutting surface can limit the movement of the housing 110 relative to the guide rail 200 in the direction from the chute 112 to the guide rail groove 111 through the abutting relationship with the first limiting surface M1.

[0091] In this way, on the one hand, it can prevent the abutting end 210 from continuing to abut and push the first end 121 in the direction from the guide rail groove 111 to the chute 112, so that the spring is overcompressed, reducing the possibility of damage to the spring. On the other hand, when the elastic member 120 moves in the direction from the guide rail groove 111 to the chute 112, the first elastic arm 123 and the second elastic arm 124 will deform and approach each other. Through the abutting relationship between the guide rail 200 and the first limiting surface M1, it can prevent the first elastic arm 123 and the second elastic arm 124 from deforming excessively, thereby reducing the possibility of the first elastic arm 123 detaching from the first limiting wall 1121 and reducing the possibility of the second elastic arm 124 detaching from the second limiting wall. On the other hand, it can avoid the elastic member 120 from moving excessively in the direction from the guide rail groove 111 to the chute 112, reducing the possibility of the elastic member 120 slipping out of the chute 112 and reducing the possibility of the second end 122 of the elastic member 120 protruding from the side of the chute 112 away from the guide rail groove 111.

[0092] In addition to setting the first limiting surface M1 to limit the movement of the housing 110 in the direction from the guide rail groove 111 to the chute 112, the present application also sets other limiting surfaces to limit the movement of the housing 110 in the direction from the guide rail groove 111 to the chute 112.

[0093] Exemplarily, in some other embodiments, in combination with Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, when the abutting end 210 abuts against the first end 121 to release the restriction of the slot 1113 on the latching end 220, the guide rail 200 abuts against the first groove wall 1114, and the first groove wall 1114 is used to restrict the movement of the housing 110 relative to the guide rail 200 in the direction from the chute 112 to the guide rail groove 111.

[0094] The first groove wall 1114 is the aforementioned other limiting surface.

[0095] The portion of the guide rail 200 for abutting against the first groove wall 1114 is the abutting end 210 of the guide rail 200. It can be seen that the abutting end 210 of the guide rail 200 can not only abut against the first end 121 of the elastic member 120, but also abut against the first groove wall 1114. However, the portion where the abutting end 210 abuts against the first end 121 is approximately located in the middle of the abutting end 210, and the portion of the abutting end 210 other than the portion abutting against the first end 121 can abut against the first groove wall 1114.

[0096] When the abutting end 210 abuts against the first end 121 to release the restriction of the slot 1113 on the latching end 220, assuming that the guide rail 200 abuts against the first groove wall 1114, the guide rail 200 can restrict the movement of the first groove wall 1114 in the direction from the chute 112 to the guide rail groove 111, thereby restricting the continuous movement of the housing 110 relative to the guide rail 200 in the direction from the chute 112 to the guide rail groove 111.

[0097] Similar to the effect brought by the first limiting surface M1, the setting of the first groove wall 1114, on the one hand, can prevent the abutting end 210 from continuously abutting against the first end 121 in the direction from the guide rail groove 111 to the chute 112, so that the spring is excessively compressed, reducing the possibility of damage to the spring. On the other hand, when the elastic member 120 moves in the direction from the guide rail groove 111 to the chute 112, the first elastic arm 123 and the second elastic arm 124 will deform and approach each other. Through the abutting relationship between the guide rail 200 and the first groove wall 1114, it can prevent the first elastic arm 123 and the second elastic arm 124 from deforming excessively, thereby reducing the possibility of the first elastic arm 123 detaching from the first limiting wall 1121 and reducing the possibility of the second elastic arm 124 detaching from the second limiting wall. On the other hand, it can avoid the elastic member 120 from moving excessively in the direction from the guide rail groove 111 to the chute 112, reducing the possibility of the elastic member 120 slipping out of the chute 112 and reducing the possibility of the second end 122 of the elastic member 120 protruding from the side of the chute 112 away from the guide rail groove 111.

[0098] It should be noted that in different designs of the present application, when the abutting end 210 abuts against the first end 121 to release the restriction of the slot 1113 on the clamping end 220, the guide rail 200 can abut only against the first limiting surface M1 and not against the first groove wall 1114, and the movement of the housing 110 in the direction from the sliding groove 112 to the guide rail groove 111 is restricted only by the first limiting surface M1. Alternatively, the guide rail 200 can abut only against the first groove wall 1114 and not against the first limiting surface M1, and the movement of the housing 110 in the direction from the sliding groove 112 to the guide rail groove 111 is restricted only by the first groove wall 1114. Alternatively, the guide rail 200 can abut against both the first limiting surface M1 and the first groove wall 1114 to jointly restrict the movement of the housing 110 in the direction from the sliding groove 112 to the guide rail groove 111 through the first limiting surface M1 and the first groove wall 1114.

[0099] Figure 7 Another exploded view of the electrical switch provided by the embodiment of the present application Figure 8 is Figure 7 an enlarged view of part B in Figure 2 , Figure 7 and Figure 8 , a second limiting surface M2 can be provided on the side of the bump 1111 facing the sliding groove 112. When the elastic member 120 is installed in the sliding groove 112, the first end 121 abuts against the second limiting surface M2.

[0100] Based on the foregoing description, the elastic member 120 can be installed in the sliding groove 112 in the direction from the sliding groove 112 to the guide rail groove 111. Based on this, by providing the second limiting surface M2 on the side of the bump 1111 facing the sliding groove 112, when the elastic member 120 is installed in the sliding groove 112, the first end 121 of the elastic member 120 abuts against the second limiting surface M2, which can restrict the movement of the first end 121 in the direction from the sliding groove 112 to the guide rail groove 111 and reduce the possibility of the elastic member 120 sliding out of the sliding groove 112. In addition, the abutment of the first end 121 of the elastic member 120 against the second limiting surface M2 can be used as a basis for the elastic member 120 to be installed in place in the sliding groove 112, which is convenient for guiding the installation of the elastic member 120 in the sliding groove 112.

[0101] Further, please continue to refer to Figure 5 and Figure 8 , in some embodiments, the housing 110 can also be provided with a tool groove 115. Combining Figure 4 and Figure 5 , the tool groove 115 is communicated with the sliding groove 112, and the tool groove 115 is used for inserting a tool to pinch the first elastic arm 123 and the second elastic arm 124 together by the tool.

[0102] The tool can be a tool such as tweezers that can clamp the first elastic arm 123 and the second elastic arm 124.

[0103] There is a gap between the tool slot 115 and the first elastic arm 123, and there is also a gap between the tool slot 115 and the second elastic arm 124. In this way, it is convenient for the tool to be inserted through these two gaps.

[0104] The tool slot 115 can be arranged on the side of the first limiting wall 1121 and the second limiting wall away from the guide rail slot 111.

[0105] During the process of installing the elastic member 120 into the sliding slot 112, when the tool is inserted into the tool slot 115 and the first elastic arm 123 and the second elastic arm 124 are pinched together, it can reduce the possibility that the first elastic arm 123 gets stuck with the first slot wall 1114 and cannot continue to move along the sliding slot 112 towards the guide rail slot 111. It can also reduce the possibility that the second elastic arm 124 gets stuck with the second slot wall and cannot continue to move along the sliding slot 112 towards the guide rail slot 111. Therefore, it is convenient for the first elastic arm 123 and the second elastic arm 124 to smoothly move into the space between the first limiting wall 1121 and the second limiting wall for proper installation, improving the installation efficiency of the elastic member 120 into the sliding slot 112.
