Description

Technical Field

[0001] The embodiments of the present application relate to the field of electrical equipment, and particularly to a switch. Background Art

[0002] As a control element for controlling the on-off of a circuit, a switch is an indispensable part of a circuit system. With the progress of technology and the improvement of people's requirements for product performance, there are more requirements for the structural stability, operation convenience, occupied space, etc. of the switch.

[0003] A movable conductive member is generally provided in the switch, and the movable conductive member is connected to operating elements such as a key and a button, so that the movable conductive member can connect or disconnect a current loop with the movement of the operating element. Moreover, multiple groups of operating elements and conductive members are usually provided in the switch, enabling a user to control the on-off of multiple current loops through one switch.

[0004] However, in the switches currently in use, it is usually necessary to connect a power input wire and an output wire corresponding to one current loop, with a complex structure and troublesome wiring operation. Therefore, how to simplify the switch structure to facilitate wiring has become a technical problem to be solved. Summary of the Utility Model

[0005] In view of the above problems, the embodiments of the present application provide a switch. The switch forms two current loops through one conductive member, two moving contact pieces and two static contact pieces, with a simple structure. When wiring, only one power input wire and two output wires need to be connected, making the assembly more convenient.

[0006] In one aspect of the embodiments of the present application, a switch is provided. The switch includes a conductive sheet, a first static contact piece, a second static contact piece, a first moving contact piece and a second moving contact piece. The opposite ends of the conductive sheet are a power input end and a current splitting end. The power input end is used to connect a power input wire, and the current splitting end is provided with a first current splitting portion and a second current splitting portion. The first current splitting portion faces the first static contact piece, the second current splitting portion faces the second static contact piece, and the first static contact piece and the second static contact piece are located on the same side of the conductive sheet. The first moving contact piece is movably arranged between the first static contact piece and the first current splitting portion to connect or separate the first static contact piece and the first current splitting portion. The second moving contact piece is movably arranged between the second static contact piece and the second current splitting portion to connect or separate the second static contact piece and the second current splitting portion.

[0007] The switch has a simple structure. When wiring, only one power input wire and two output wires need to be connected, making the assembly more convenient. Moreover, in this switch, the first static contact piece and the second static contact piece are located on the same side of the conductive sheet, with a compact overall structure. The conductive sheet only needs a smaller volume to meet the power supply requirements of the two static contact pieces, and the required cost is lower.

[0008] In an alternative embodiment, one end of the first moving contact piece contacts the outer surface of the first current shunting portion facing the first stationary contact piece, and the other end of the first moving contact piece can approach or move away from the first stationary contact piece. One end of the second moving contact piece contacts the outer surface of the second current shunting portion facing the second stationary contact piece, and the other end of the second moving contact piece can approach or move away from the second stationary contact piece.

[0009] In this embodiment, one end of the moving contact piece is always in contact with the conductive piece, and the other end of the moving contact piece can move closer to or away from the stationary contact piece. It has high reliability, flexible movement, requires a small movement space for the moving contact piece, has a simple and compact overall structure, and is convenient for assembly.

[0010] In an alternative embodiment, the outer surface of the first current shunting portion facing the first stationary contact piece and the outer surface of the second current shunting portion facing the second stationary contact piece belong to the same surface of the conductive piece.

[0011] In this embodiment, the ends of the first moving contact piece and the second moving contact piece in contact with the conductive piece can be located on the same plane, which is convenient for the precise positioning of the first moving contact piece and the second moving contact piece, convenient for controlling the movable range of the first moving contact piece and the second moving contact piece, and improves the accuracy and reliability when the first moving contact piece and the second moving contact piece connect or disconnect the current circuit.

[0012] In an alternative embodiment, the switch further includes a first elastic member and a second elastic member. The first elastic member presses one end of the first moving contact piece against the outer surface of the first current shunting portion facing the first stationary contact piece, and the second elastic member presses one end of the second moving contact piece against the outer surface of the second current shunting portion facing the second stationary contact piece.

[0013] In this embodiment, the contact between the first moving contact piece and the second moving contact piece and the conductive piece is stable, and the first moving contact piece and the second moving contact piece move more smoothly. Moreover, its structure is simple, which is convenient for installation and maintenance.

[0014] In an alternative embodiment, the switch further includes a movable first button and a movable second button. The first button is connected to the first moving contact piece so that the first moving contact piece moves synchronously with the first button. The second button is connected to the second moving contact piece so that the second moving contact piece moves synchronously with the second button.

[0015] In this embodiment, the structures of the first button and the second button are simple. The user can control the connection and disconnection of the first current circuit and the second current circuit with a simple pressing operation. The operation method is intuitive and convenient, and the user can obtain instant feedback, providing a better user experience.

[0016] In an alternative embodiment, the switch further includes a first transmission member and a second transmission member. The first button is connected to the first moving contact piece through the first transmission member so that the movement of the first button is synchronized to the first moving contact piece through the first transmission member. The second button is connected to the second moving contact piece through the second transmission member so that the movement of the second button is synchronized to the second moving contact piece through the second transmission member.

[0017] In this method, the button is connected to the moving contact piece through a transmission member, so that each moving contact piece can move synchronously with each button to connect or disconnect the current circuit corresponding to each button. The on-off control of the current circuit is reliable and safer.

[0018] In an optional manner, the conductive sheet is bent in sequence from the shunt end to the incoming line end to form a first bending section, a second bending section and a third bending section, and the first bending section, the second bending section and the third bending section form a groove structure.

[0019] This method is more convenient for positioning, installation and wiring, and this structural form has strong stability. It can reduce material consumption while ensuring that the conductive parts have sufficient current-carrying cross-sectional area, and the cost is low.

[0020] In an optional manner, the switch further comprises a frame, on which a first bracket is arranged, and a groove structure surrounded by the first bending segment, the second bending segment and the third bending segment is clamped on the first bracket.

[0021] In this way, the conductive sheet can be directly clamped on the first bracket to complete the positioning and installation of the conductive sheet, and its structure is simple and easy to install and disassemble. In addition, the groove structure surrounded by the first bending section, the second bending section and the third bending section is clamped on the first bracket, and its installation is stable and not easy to fall off.

[0022] In an optional manner, the first bracket is provided with a first abutting surface and a second abutting surface facing away from each other. The second bending section is provided with a boss surface facing the diversion end, the boss surface abuts the first abutting surface, and a side of the first bending section facing away from the diversion end abuts the second abutting surface.

[0023] This method positions and cooperates with the first bracket through the boss surface and the side of the first bending section facing away from the shunt end, which simplifies the matching structure of the conductive sheet and the first bracket, has lower requirements on the dimensional accuracy of each part, is easier to process and assemble, and can further save materials.

[0024] In an optional manner, the switch further comprises a frame. A second bracket and a third bracket are arranged on the frame, and the first static contact piece and the second static contact piece are bent to form a groove structure. The first static contact piece is clamped on the second bracket, and the second static contact piece is clamped on the third bracket.

[0025] In this manner, the first stationary contact piece and the second stationary contact piece are both configured as a bending structure forming a groove, which is convenient for processing and installation. The first stationary contact piece and the second stationary contact piece have the same or similar structures, which is convenient for batch processing and replacement.

[0026] In the switch provided by the embodiment of the present application, the conductive sheet, the first moving contact piece, the second moving contact piece, the first static contact piece, and the second static contact piece form two current loops, and the first moving contact piece and the second moving contact piece can respectively control the on-off of the two current loops. Its overall structure is simple. When wiring, only one incoming power wire and two outgoing power wires need to be connected, making the assembly more convenient. Moreover, in this switch, the first static contact piece and the second static contact piece are located on the same side of the conductive sheet, and the overall structure is compact. The conductive sheet only needs a relatively small volume to meet the power supply requirements of the two static contact pieces, and the required cost is relatively low.

[0053] The switch provided by the present application is as Figure 1 shown Figure 1 and is an exploded view of a switch provided by an embodiment of the present application. The switch includes a frame 10, an operating component 20, and a conductive component 30.

[0054] The frame 10 is a frame structure that provides an installation space and support for the operating component 20 and the conductive component 30. The frame 10 is used to connect to an installation base surface such as a wall surface to install the switch on the installation base surface. Sufficient installation space is reserved in the frame 10 to accommodate the operating component 20 and the conductive component 30. The installation space may specifically be a cavity structure, and auxiliary installation or positioning structures such as brackets and struts may be provided in the cavity structure, which are not specifically limited herein.

[0055] The frame 10 has sufficient strength to support the operating component 20 and the conductive component 30 with weight. At the same time, the strength of the frame 10 needs to ensure that the frame 10 can support the pressing operation received by the operating component 20, that is, the frame 10 can withstand a certain pressing force without being damaged.

[0056] The operating component 20 and the conductive component 30 are installed on the frame 10. The operating component 20 and the conductive component 30 are connected to respond to the user's power-on or power-off operation and control the conductive component 30 to connect or disconnect the current loop. There are many structural forms of the operating component 20. For example, the operating component 20 may be a pressing structure to enable the user to perform a power-on or power-off operation through a pressing action. The operating component 20 may also be a rotary structure to enable the user to perform a power-on or power-off operation through a rotating action.

[0057] The conductive component 30 is composed of a plurality of conductive parts, and the conductive component 30 can be conductively connected with the incoming power conductor and the outgoing power conductor to form a current loop. Figure 1 As shown, the conductive component 30 includes a conductive sheet 31 , a first stationary contact sheet 32 , a second stationary contact sheet 33 , a first movable contact sheet 34 and a second movable contact sheet 35 .

[0058] The conductive sheet 31 is a structure connected to the incoming power conductor. The conductive sheet 31 can be made of a metal material with high conductivity such as copper or copper alloy to ensure the efficiency and stability of current transmission. The two opposite ends of the conductive sheet 31 are the incoming line end and the shunt end. The incoming line end is used to connect the incoming power conductor, and the shunt end is used to divide the current into two parts, and then the two parts of the current are transmitted to the two outgoing power conductors through different moving contact pieces and static contact pieces.

[0059] like Figure 1 and Figure 2 As shown, Figure 2 : This is a cross-sectional view of the location of the conductive sheet of the switch involved in the embodiment of the present application. Among them, the shunt end of the conductive sheet 31 is provided with a first shunt portion 311 and a second shunt portion 312, and the first shunt portion 311 and the second shunt portion 312 are spaced a certain distance apart to shunt the current. The first shunt portion 311 and the second shunt portion 312 can be symmetrical protruding structures, such as making the overall structure of the conductive sheet 31 into a "X" shape, the head of the conductive sheet 31 is the inlet end, and the two legs are the first shunt portion 311 and the second shunt portion 312.

[0060] The first static contact piece 32 and the second static contact piece 33 are respectively used to connect two separate power outgoing wires. In addition, the first shunt part 311, the first moving contact piece 34 and the first static contact piece 32 are arranged relative to each other in space, so that the current of the first shunt part 311 can be guided to the first static contact piece 32 through the first moving contact piece 34, so as to form a contact switch of the first current loop. The second shunt part 312, the second moving contact piece 35 and the second static contact piece 33 are arranged relative to each other in space, so that the current of the second shunt part 312 can be guided to the second static contact piece 33 through the second moving contact piece 35, so as to form a contact switch of the second current loop.

[0061] The relative positions of the conductive parts are arranged as follows: Figure 1 , Figure 3 and Figure 4 As shown, Figure 3 is a cross-sectional view of the location of the conductive sheet of the switch involved in the embodiment of the present application, Figure 4This is a cross-sectional view of the position of the first static contact piece of the switch involved in the embodiment of the present application. Among them, the first current shunting part 311 faces the first static contact piece 32, the second current shunting part 312 faces the second static contact piece 33, and the first static contact piece 32 and the second static contact piece 33 are located on the same side of the conductive sheet 31. The first moving contact piece 34 is movably arranged between the first static contact piece 32 and the first current shunting part 311 to connect or separate the first static contact piece 32 and the first current shunting part 311. The second moving contact piece 35 is movably arranged between the second static contact piece 33 and the second current shunting part 312 to connect or separate the second static contact piece 33 and the second current shunting part 312.

[0062] The first moving contact piece 34 and the first static contact piece 32 form the moving contact point and the static contact point of the first current loop, and the second moving contact piece 35 and the second static contact piece 33 form the moving contact point and the static contact point of the second current loop. When the first moving contact piece 34 connects the first current shunting part 311 and the first static contact piece 32, the first current loop is switched on. When the first moving contact piece 34 separates the first current shunting part 311 and the first static contact piece 32, the first current loop is switched off. When the second moving contact piece 35 connects the second current shunting part 312 and the second static contact piece 33, the second current loop is switched on. When the second moving contact piece 35 separates the second current shunting part 312 and the second static contact piece 33, the second current loop is switched off.

[0063] In this embodiment, the moving contact piece is equivalent to a bridging structure arranged between the conductive sheet 31 and the static contact piece. In one structural form, the moving contact piece can move to a position where it simultaneously contacts the conductive sheet 31 and the static contact piece when the current loop needs to be switched on, and separates from the conductive sheet 31 and the static contact piece simultaneously when the current loop needs to be switched off. In another structural form, one end of the moving contact piece can always be in contact with the conductive sheet 31, and the other end can approach or move away from the static contact piece to switch on or off the current loop. In another structural form, one end of the moving contact piece can always be in contact with the static contact piece, and the other end can approach or move away from the conductive sheet 31 to switch on or off the current loop.

[0064] The above-mentioned moving contact piece and static contact piece refer to any set of moving contact piece and static contact piece that can conduct current, for example, the first moving contact piece and the first static contact piece, or the second moving contact piece and the second static contact piece.

[0065] Exemplarily, a feasible way is as Figure 3 and Figure 4 shown, one end of the first moving contact piece 34 contacts the outer surface of the first current shunting part 311 facing the first static contact piece 32, and the other end of the first moving contact piece 34 can approach or move away from the first static contact piece 32. One end of the second moving contact piece 35 contacts the outer surface of the second current shunting part 312 facing the second static contact piece 33, and the other end of the second moving contact piece 35 can approach or move away from the second static contact piece 33.

[0066] In this way, one end of the moving contact piece is always in contact with the conductive piece 31, and the other end of the moving contact piece can move closer to or away from the static contact piece. It has high reliability, flexible movement, requires a small moving space for the moving contact piece, the overall structure is simple and compact, and the assembly is convenient.

[0067] Since both the first static contact piece 32 and the second static contact piece 33 are located on the same side, the outer surface of the first shunt portion 311 facing the first static contact piece 32 and the outer surface of the second shunt portion 312 facing the second static contact piece 33 have the same orientation. The first moving contact piece 34 and the second moving contact piece 35 are substantially in contact with the first shunt portion 311 and the second shunt portion 312 respectively from the same side, which can make the conductive parts more compact, resulting in a smaller volume occupied by the overall structure, and facilitating the alignment between the conductive parts when installing the conductive parts.

[0068] A feasible way is as Figure 1 and Figure 2 shown. The outer surface of the first shunt portion 311 facing the first static contact piece 32 and the outer surface of the second shunt portion 312 facing the second static contact piece 33 belong to the same surface of the conductive piece 31. That is to say, the outer surface of the first shunt portion 311 facing the first static contact piece 32 and the outer surface of the second shunt portion 312 facing the second static contact piece 33 are both part of a plane without any bending.

[0069] In this way, the ends of the first moving contact piece 34 and the second moving contact piece 35 in contact with the conductive piece 31 can be located on the same plane, which is convenient for the precise positioning of the first moving contact piece 34 and the second moving contact piece 35, convenient for controlling the movable range of the first moving contact piece 34 and the second moving contact piece 35, and improving the accuracy and reliability when the first moving contact piece 34 and the second moving contact piece 35 turn on and off the current circuit.

[0070] There are many ways for the moving contact piece to contact the outer surface of the conductive piece 31. For example, the outer surfaces of the moving contact piece and the conductive piece 31 can be always in contact through connection methods such as hinging, or the moving contact piece can be pressed against the outer surface of the conductive piece 31 through components.

[0071] A feasible way is as Figure 1 shown. The switch further includes a first elastic member 41 and a second elastic member 42. The first elastic member 41 presses one end of the first moving contact piece 34 against the outer surface of the first shunt portion 311 facing the first static contact piece 32. The second elastic member 42 presses one end of the second moving contact piece 35 against the outer surface of the second shunt portion 312 facing the second static contact piece 33.

[0072] Among them, the elastic member can specifically be structures such as springs and elastic sheets, which are not limited herein. The first moving contact piece 34 and the second moving contact piece 35 are respectively pressed against the first current-dividing portion 311 and the second current-dividing portion 312 through the first elastic member 41 and the second elastic member 42. The contact between the first moving contact piece 34 and the second moving contact piece 35 and the conductive sheet 31 is stable, and the first moving contact piece 34 and the second moving contact piece 35 are smoother when moving. Moreover, its structure is simple, facilitating installation and maintenance.

[0073] In this embodiment, the arrangement of the first current-dividing portion 311 and the second current-dividing portion 312 enables the conductive sheet 31 itself to perform current division. Just by connecting a power input wire to the conductive sheet 31, the access of the power input wires for two current loops is completed simultaneously. The overall structure is simple and the assembly is convenient. Moreover, the conductive sheet 31 is a sheet-like structure, and the first static contact piece 32 and the second static contact piece 33 are located on the same side of the conductive sheet 31. The conductive sheet 31 can meet the power-on requirements of the two static contact pieces with a relatively small volume. The overall structure is compact, occupying less space and requiring lower costs.

[0074] In this embodiment, the first moving contact piece 34 and the second moving contact piece 35 are respectively connected to different operating elements so that the user can respectively control the on / off of the first moving contact piece 34 and the second moving contact piece 35 through different operating elements.

[0075] A feasible way is as Figure 1 shown. The operation assembly 20 of the switch includes a movable first button 21 and a movable second button 22. The first button 21 is connected to the first moving contact piece 34, so that the first moving contact piece 34 moves synchronously with the first button 21. The second button 22 is connected to the second moving contact piece 35, so that the second moving contact piece 35 moves synchronously with the second button 22.

[0076] Both the first button 21 and the second button 22 are operating elements and are movably arranged on the frame 10, and their exposed parts are for the user to press. The first button 21 and the second button 22 can be arranged side by side at intervals or in an arranged manner. The first button 21 and the second button 22 can be set in a structure form of pressing in and pressing out to control the on / off of the first current loop and the second current loop through the pressing-in operation and pressing-out operation of the first button 21 and the second button 22. The first button 21 and the second button 22 can also be set as lever-type flip buttons to control the on / off of the first current loop and the second current loop by pressing the relative ends of the first button 21 and the second button 22.

[0077] In this way, the structures of the first button 21 and the second button 22 are simple. The user only needs a simple pressing operation to control the on / off of the first current loop and the second current loop. The operation method is intuitive and convenient, and the user can obtain instant feedback, and the user experience will be better.

[0078] The first button 21 and the second button 22 can be directly connected to the first movable contact piece 34 and the second movable contact piece 35 respectively, or can be connected through a transmission member to obtain better motion transmission effect and protect the user's electrical safety.

[0079] The specific implementation is as Figure 1 shown. The operation component 20 of the switch further includes a first transmission member 23 and a second transmission member 24. The first button 21 is connected to the first movable contact piece 34 through the first transmission member 23, so that the movement of the first button 21 is synchronized to the first movable contact piece 34 through the first transmission member 23. The second button 22 is connected to the second movable contact piece 35 through the second transmission member 24, so that the movement of the second button 22 is synchronized to the second movable contact piece 35 through the second transmission member 24.

[0080] The first transmission member 23 and the second transmission member 24 can be made of metal or high-strength plastic to make them have sufficient rigidity and durability. The first transmission member 23 is connected to the first button 21 and the first movable contact piece 34 at the same time to transmit the movement of the first button 21 to the first movable contact piece 34, thereby controlling the on-off of the first current loop. The second transmission member 24 is connected to the second button 22 and the second movable contact piece 35 at the same time to transmit the movement of the second button 22 to the second movable contact piece 35, thereby controlling the on-off of the second current loop.

[0081] The first transmission member 23 and the second transmission member 24 can specifically be single-piece parts that can move synchronously with the first button 21 and the second button 22, or can be composed of multiple parts that play a transmission role. The first transmission member 23 and the second transmission member 24 can specifically include a lever structure, a gear structure, elastic members such as springs, a transmission rod structure, etc., and no specific limitation is made here.

[0082] In this way, the button is connected to the movable contact piece through the transmission member, so that each movable contact piece can move synchronously with each button respectively to connect or disconnect the current loop corresponding to each button. The on-off control of the current loop is reliable and the safety is higher.

[0083] In addition, in this embodiment, the conductive sheet 31, the first static contact piece 32 and the second static contact piece 33 are all arranged in a sheet structure, and it can be a bent sheet structure to facilitate the fixed installation of the conductive sheet 31, the first static contact piece 32 and the second static contact piece 33 on the frame 10.

[0084] Taking the conductive sheet 31 as an example, a feasible way is as Figure 2 shown. The conductive sheet 31 is sequentially bent with a first bent section 313, a second bent section 314 and a third bent section 315 in the direction from the shunt end to the incoming line end, and the first bent section 313, the second bent section 314 and the third bent section 315 enclose a groove structure.

[0085] The conductive sheet 31 can be set as a long strip-shaped sheet structure, and through stamping or other methods, part of the structure at the incoming wire end can be bent into a three-stage bending structure, such that the first bending section 313 is bent relative to the shunt end, the second bending section 314 is bent relative to the first bending section 313, and the third bending section 315 is bent relative to the second bending section 314. Moreover, the bending lines at each bending part are perpendicular to the direction of the shunt end relative to the incoming wire end.

[0086] The conductive sheet 31 should have sufficient thickness to ensure it has sufficient current-carrying cross-sectional area. And when the first bending section 313 is bent, some protruding ribs 318 can also be bent out to ensure the current-carrying cross-sectional area when the conductive sheet 31 shunts.

[0087] The first bending section 313, the second bending section 314, and the third bending section 315 enclose a groove structure, making the incoming wire end of the conductive sheet 31 form a three-dimensional structure convenient for installation. The incoming wire end of the conductive sheet 31 can be directly stuck on structures such as the brackets and columns of the frame 10 for installation, which is more convenient for positioning installation and wiring. At the same time, this structural form has strong stability, can reduce the material usage while ensuring that the conductive part has sufficient current-carrying cross-sectional area, and has a lower cost.

[0088] There are many ways for the conductive sheet 31 to be stuck on the frame 10 by its incoming wire end. One feasible way is as Figure 5 shown. Figure 5 This is a schematic structural diagram when the conductive sheet, the first static contact piece, and the second static contact piece of the switch involved in the embodiment of the present application are installed on the frame. Among them, a first bracket 11 is provided on the frame 10, and the groove structure enclosed by the first bending section 313, the second bending section 314, and the third bending section 315 is stuck on the first bracket 11.

[0089] The first bracket 11 is a protruding structure provided on the frame 10. Specifically, the first bracket 11 can be composed of multiple support plates or can be composed of structures such as columns. The shape of the first bracket 11 corresponds to the shape of the conductive sheet 31, enabling the first bracket 11 to fit the conductive sheet 31. Limit structures such as card slots and arc-shaped bosses can be specifically provided on the first bracket 11 to limit the movement of the conductive sheet 31 in multiple directions, so that the conductive sheet 31 is fixedly installed on the frame 10.

[0090] In this way, the conductive sheet 31 can be positioned and installed directly by being stuck on the first bracket 11. Its structure is simple and convenient for installation and disassembly. Moreover, the groove structure enclosed by the first bending section 313, the second bending section 314, and the third bending section 315 is stuck on the first bracket 11, and its installation is firm and not easy to fall off.

[0091] There are many ways for the groove structure formed by the first bending section 313, the second bending section 314, and the third bending section 315 to be stuck on the first bracket 11. For example, the first bracket 11 can be set to a structure that can completely hold the first bending section 313, the second bending section 314, and the third bending section 315. Or, a protruding structure 316 can be provided on the first bending section 313, the second bending section 314, and the third bending section 315 for auxiliary fixation.

[0092] A feasible way is as Figure 6 and Figure 7 shown in Figure 6 is a partial schematic view from the first perspective when the conductive sheet of the switch involved in the embodiment of the present application is stuck on the first bracket. Figure 7 is a partial schematic view from the first perspective when the conductive sheet of the switch involved in the embodiment of the present application is stuck on the first bracket. Among them, the first bracket 11 is provided with a first resisting surface 111 and a second resisting surface 112 that face away from each other. A convex table surface 317 facing the shunt end is provided on the second bending section 314, and the convex table surface 317 abuts against the first resisting surface 111, and the surface of the first bending section 313 facing away from the shunt end abuts against the second resisting surface 112.

[0093] A protruding structure 316 is provided on the second bending section 314, and it can be specifically provided on the side surface of the second bending section 314. Moreover, the protruding structure 316 can be provided in pairs. For example, a protruding structure 316 is provided on each of the opposite two surfaces of the second bending section 314. The orientation of the convex table surface 317 of the protruding structure 316 is opposite to the orientation of the surface of the first bending section 313 facing away from the shunt end. Thus, when the convex table surface 317 abuts against the first resisting surface 111 and the surface of the first bending section 313 facing away from the shunt end abuts against the second resisting surface 112, the conductive sheet 31 is restricted from moving in the relative direction between the shunt end and the connection end.

[0094] This method performs positioning and cooperation with the first bracket 11 through the convex table surface 317 and the surface of the first bending section 313 facing away from the shunt end, simplifies the engaging structure between the conductive sheet 31 and the first bracket 11, has less requirements for the dimensional accuracy of each part, is more convenient for processing and assembly, and can further save materials.

[0095] This method only restricts the movement of the conductive sheet 31 in the relative direction between the shunt end and the connection end. In order to fix the conductive sheet 31 on the frame 10, the conductive sheet 31 can be pressed on the first bracket 11 through components such as transmission parts, so that the conductive sheet 31 is completely fixed. Additionally, structures such as screws and bolts can be used to further fix and install the conductive sheet 31 on the frame 10, which is not limited here.

[0096] The structural forms and installation methods of the first static contact piece 32 and the second static contact piece 33 can be analogous to those of the inlet end of the conductive piece 31.

[0097] Exemplarily, a feasible way is as Figure 1 , Figure 5 and Figure 8 shown. Figure 8 FIG. 11 is a schematic structural view of the first static contact piece of the switch according to the embodiment of the present application. Among them, a second bracket 12 and a third bracket 13 are provided on the frame 10. Both the first static contact piece 32 and the second static contact piece 33 are bent to form a groove structure. The first static contact piece 32 is stuck on the second bracket 12, and the second static contact piece 33 is stuck on the third bracket 13.

[0098] Both the first static contact piece 32 and the second static contact piece 33 can be bent into a three-section structure similar to the inlet end of the conductive piece 31, and each section encloses a groove structure, so as to be fixedly installed on the frame 10 and to facilitate connecting the first static contact piece 32 and the second static contact piece 33 to the power supply wire. Second brackets 12 and third brackets 13 corresponding to the first static contact piece 32 and the second static contact piece 33 are provided on the frame 10. The second brackets 12 and the third brackets 13 are protruding structures similar to the first bracket 11 for installing the first static contact piece 32 and the second static contact piece 33.

[0099] In this way, both the first static contact piece 32 and the second static contact piece 33 are provided with a bent structure forming a groove, which is convenient for processing and installation. The structures of the first static contact piece 32 and the second static contact piece 33 are the same or similar, which is convenient for mass processing and replacement.

[0100] The shape of the second bracket 12 corresponds to the shape of the first static contact piece 32, so that the second bracket 12 can fit the first static contact piece 32. The shape of the third bracket 13 corresponds to the shape of the second static contact piece 33, so that the third bracket 13 can fit the second static contact piece 33. Moreover, the second bracket 12 and the third bracket 13 are separated by a certain distance, so that the installed first static contact piece 32 is opposite to the first shunt portion 311, and the installed second static contact piece 33 is opposite to the second shunt portion 312. Limit structures such as clamping grooves and arc-shaped bosses can also be provided on the second bracket 12 and the third bracket 13 to limit the movement of the first static contact piece 32 and the second static contact piece 33 in multiple directions, so that the first static contact piece 32 and the second static contact piece 33 can be fixedly installed on the frame 10.

[0101] There are also many ways to set the first static contact piece 32 and the second static contact piece 33 on the second bracket 12 and the third bracket 13. For example, the second bracket 12 can be set as a structure that can completely clamp the first static contact piece 32, and the third bracket 13 can be set as a structure that can completely clamp the second static contact piece 33. Or, a protruding structure 316 can also be provided on the first static contact piece 32 and the second static contact piece 33 for auxiliary fixation.

[0102] When the protruding structure 316 is provided on the first stationary contact piece 32 and the second stationary contact piece 33, it can be analogous to the implementation manner of positioning by providing the protruding structure 316 on the conductive piece 31, and no redundant description will be given here. Moreover, when the protruding structure 316 is provided, the protruding structure 316 can be provided in pairs. For example, a pair of protruding structures 316 can be provided on two opposite side surfaces of the first stationary contact piece 32 to improve the positioning and fixing effect.

[0103] In addition, on the basis of the above embodiments, other conductive parts in more forms can also be provided in the switch. More shunt parts can also be provided at the shunt end of the conductive piece 31, and correspondingly, more moving contact pieces and stationary contact pieces can be provided, which will not be limited here.

[0104] In summary, in the switch described above, the conductive piece, the first moving contact piece, the second moving contact piece, the first stationary contact piece and the second stationary contact piece form two current loops, and the first moving contact piece and the second moving contact piece can respectively control the on-off of the two current loops. Its overall structure is simple. When wiring, only one incoming power wire and two outgoing power wires need to be connected, and the assembly is more convenient. Moreover, in this switch, the first stationary contact piece and the second stationary contact piece are located on the same side of the conductive piece, the overall structure is compact, and the conductive piece only needs a smaller volume to meet the power supply requirements of the two stationary contact pieces, and the required cost is lower.
