Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-voltage electrical apparatus, in particular to a switch assembly. BACKGROUND

[0002] The switch assembly can control the on-off of the circuit, provide protection for the safety of the circuit, and reduce the possibility of expanding the fault in the circuit. The switch assembly includes a switch body and a wiring accessory in cooperation. The switch body can be a circuit breaker, a relay, or other switch electrical apparatus.

[0003] Based on the structure of the existing switch assembly, the switch body is usually screwed with the wiring accessory, so that the assembly efficiency of the switch body and the wiring accessory is low, and then the use of the switch assembly is high when the switch assembly is overhauled and maintained. SUMMARY

[0004] The present application provides a switch assembly, which can improve the assembly efficiency of the switch body and the wiring accessory, and then reduce the labor cost in the overhauling and maintenance process of the switch assembly, and reduce the use cost of the switch assembly.

[0005] In a first aspect, the present application provides a switch assembly. The switch assembly includes a switch body and a wiring accessory. The switch body includes a first housing and a first wiring board. The first wiring board is fixedly installed in the first housing. The first housing is provided with a first incoming line port. The setting position of the first wiring board corresponds to the setting position of the first incoming line port. The wiring accessory includes a second housing and a second wiring board. The second housing is detachably connected with the first housing. The side wall of the second housing is provided with a second incoming line port. An external lead wire extends into the second housing and the second wiring board from the second incoming line port to be electrically connected. The setting position of the second wiring board corresponds to the setting position of the first incoming line port. At least part of the second wiring board is arranged outside the second housing. The second wiring board arranged outside the second housing can extend into the first housing and elastically abut against the first wiring board from the first incoming line port.

[0006] In the examples of the present application, the switch body and the wiring accessory are detachably connected, the first wiring board and the first shell are part of the switch body, and the second wiring board and the second shell are part of the wiring accessory. The first shell is provided with a first incoming line port, and the setting positions of the first wiring board and the second wiring board correspond to the setting position of the first incoming line port. Part of the second wiring board is arranged outside the second shell, and the part of the second wiring board arranged outside the second shell can extend into the first shell from the first incoming line port and elastically abut the first wiring board to realize the electrical connection between the wiring accessory and the switch body. Compared with the prior art, the electrical connection between the wiring accessory and the switch body is realized by threaded connection. In the examples of the present application, the second wiring board is arranged to extend into the first shell and elastically abut the first wiring board, so that the electrical connection between the wiring accessory and the switch body is realized, the electrical connection between the wiring accessory and the switch body is simpler, the assembly efficiency of the wiring accessory and the switch body can be improved, and the use cost of the switch assembly can be reduced.

[0007] In addition, compared with the electrical connection between the wiring accessory and the switch body realized by threaded connection, in the examples of the present application, the first wiring board and the second wiring board elastically abut each other through deformation, which can avoid the situation that the wiring accessory and the switch body are in virtual contact due to thread slipping or the torque not reaching the target torque value, and can ensure the contact reliability of the first wiring board and the second wiring board, thereby ensuring the connection reliability of the wiring accessory and the switch body.

[0008] In some possible implementations, the first wiring board includes a first sub-board and a second sub-board connected to each other, the first sub-board is substantially parallel to the direction in which the second wiring board extends into the first incoming line port, the second sub-board is substantially perpendicular to the first sub-board, and the second sub-board is arranged on the side of the first sub-board away from the first incoming line port. The second wiring board includes a third sub-board and a fourth sub-board connected to each other, the third sub-board elastically abuts the first sub-board when extending into the first shell from the first incoming line port, and the third sub-board elastically abuts the first sub-board at least once, the fourth sub-board is substantially perpendicular to the third sub-board, and the fourth sub-board elastically abuts the second sub-board.

[0009] In the examples of the present application, the first sub-plate and the second sub-plate are part of the first wiring board, the third sub-plate and the fourth sub-plate are part of the second wiring board, the third sub-plate elastically abuts against the first sub-plate, and the fourth sub-plate elastically abuts against the second sub-plate. Since the second sub-plate is substantially perpendicular to the first sub-plate, and the fourth sub-plate is substantially perpendicular to the third sub-plate, the position where the third sub-plate elastically abuts against the first sub-plate and the position where the fourth sub-plate elastically abuts against the second sub-plate are located in different planes. The position where the third sub-plate elastically abuts against the first sub-plate is independent of the position where the fourth sub-plate elastically abuts against the second sub-plate, which can reduce the possibility of mutual influence between the position where the third sub-plate elastically abuts against the first sub-plate and the position where the fourth sub-plate elastically abuts against the second sub-plate, ensure the contact reliability of the first wiring board and the second wiring board, and further ensure the use reliability of the switch assembly.

[0011] In the examples of the present application, at least one first protrusion is arranged on the side of the third sub-plate facing the first sub-plate, so that the first protrusion can abut against the first sub-plate in the case of elastic abutment between the first wiring board and the second wiring board. This makes the contact between the first protrusion and the first sub-plate more reliable, increases the effective contact area of the third sub-plate and the first sub-plate, ensures the contact reliability of the first wiring board and the second wiring board, and further ensures the use reliability of the switch assembly.

[0012] In some possible implementation manners, the first sub-plate is provided with a plurality of first grooves at intervals on the side facing the third sub-plate, the first sub-plate between any two adjacent first grooves is a first contact surface, and at least part of the first contact surface elastically abuts against the third sub-plate. Alternatively, the third sub-plate is provided with a plurality of second grooves at intervals on the side facing the first sub-plate, the third sub-plate between any two adjacent second grooves is a second contact surface, and at least part of the second contact surface elastically abuts against the first sub-plate.

[0013] In the examples of the present application, in the case where a plurality of first grooves are arranged at intervals on the side of the first sub-plate facing the third sub-plate, the plurality of first grooves divide the side of the first sub-plate facing the third sub-plate into a plurality of first contact surfaces arranged at intervals. The first contact surfaces elastically abut against the third sub-plate, which can reduce the possibility of mutual influence between different first contact surfaces, and further increase the effective contact area of the first sub-plate and the third sub-plate, and ensure the contact reliability of the first sub-plate and the third sub-plate.

[0014] In the case that the plurality of second grooves are arranged at intervals on the side of the third sub-plate facing the first sub-plate, the plurality of second grooves divide the side of the third sub-plate facing the first sub-plate into a plurality of second contact surfaces arranged at intervals, and the second contact surfaces elastically abut against the first sub-plate, which can reduce the possibility of mutual influence of different second contact surfaces, and further can increase the effective contact area of the third sub-plate and the first sub-plate, and ensure the contact reliability of the third sub-plate and the first sub-plate.

[0015] In some possible implementation manners, the first terminal block further includes a fifth sub-plate, the fifth sub-plate is arranged at an end of the second sub-plate away from the first sub-plate, and the fifth sub-plate is arranged on the side of the second sub-plate facing the first incoming line port. The second terminal block further includes a sixth sub-plate, the sixth sub-plate is arranged at an end of the fourth sub-plate away from the third sub-plate, and the sixth sub-plate extends into the first incoming line port along the direction of the second terminal block, the sixth sub-plate and the third sub-plate are located on the same side of the fourth sub-plate, the maximum distance between the sixth sub-plate and the third sub-plate is less than the minimum distance between the fifth sub-plate and the first sub-plate, and the fifth sub-plate and the sixth sub-plate elastically abut against each other.

[0016] In the examples of the present application, the fifth sub-plate is a part of the first terminal block, and the fifth sub-plate is arranged at an end of the second sub-plate away from the first sub-plate, and the sixth sub-plate is a part of the second terminal block, and the sixth sub-plate is arranged at a part of the first sub-plate away from the third sub-plate, therefore, the abutting position of the sixth sub-plate and the fifth sub-plate is independent of the abutting position of the first sub-plate and the third sub-plate, and the abutting position of the sixth sub-plate and the fifth sub-plate is independent of the abutting position of the second sub-plate and the fourth sub-plate, which can reduce the possibility of mutual influence between the abutting position of the sixth sub-plate and the fifth sub-plate and the abutting position of the first sub-plate and the third sub-plate and the abutting position of the second sub-plate and the fourth sub-plate, and ensure the contact reliability of the first terminal block and the second terminal block.

[0017] In addition, since the maximum distance between the sixth sub-plate and the third sub-plate is less than the maximum distance between the fifth sub-plate and the first sub-plate, the contact reliability of the sixth sub-plate and the fifth sub-plate and the contact reliability between the third sub-plate and the first sub-plate can be further ensured, and the contact reliability of the first terminal block and the second terminal block is further ensured.

[0018] In some possible implementation manners, the second shell includes a first sub-shell and a second sub-shell, and the wiring accessory includes an accessory body and a base. The accessory body further includes a first connecting piece and the first sub-shell, a side wall of the first sub-shell is provided with a mounting hole, the first connecting piece is fixedly installed to the inside of the first sub-shell, and the first connecting piece is arranged at a position corresponding to the arrangement position of the mounting hole. The first sub-shell is detachably connected with the first shell, the first connecting piece is fixedly connected with the second wiring board, and at least part of the second wiring board is located outside the first sub-shell. The base includes a second connecting piece and the second sub-shell which are fixedly connected, the second sub-shell is detachably connected with the first sub-shell, the second connecting piece extending to the second sub-shell is detachably connected with the first connecting piece by extending into the first sub-shell from the mounting hole, and a side wall of the second sub-shell is provided with a second wire inlet.

[0019] In the examples of the present application, since the first connecting piece is part of the accessory body, the accessory body and the second wiring board are part of the wiring accessory, and the second wiring board is connected with the switch body, the electrical connection between the accessory body and the switch body can be realized through the fixed connection between the first connecting piece and the second wiring board. On this basis, the external lead wire is connected with the accessory body through the base, and the external lead wire can be connected with the switch body through the accessory body, thereby realizing the connection between the external lead wire and the switch body.

[0020] In addition, since the first sub-shell and the first connecting piece are part of the accessory body, and the second sub-shell and the second connecting piece are part of the base, the detachable connection between the accessory body and the base can be realized through the detachable connection between the first sub-shell and the second sub-shell, and the detachable connection between the first connecting piece and the second connecting piece, so that the switch body and the accessory body are detachably connected with the base as a whole during the maintenance or repair of the switch assembly, and the external lead wire corresponding to the single switch body is avoided to be removed, thereby reducing the labor cost caused by maintenance or repair in the use of the switch assembly.

[0021] In some possible implementation manners, the first connecting piece includes first and second side walls arranged opposite to each other, and the second connecting piece includes third and fourth side walls arranged opposite to each other, the third and fourth side walls are installed between the first and second side walls, and the minimum distance between the first and second side walls is smaller than the maximum distance between the third and fourth side walls.

[0022] In the examples of the present application, since the first side wall and the second side wall are part of the first connecting piece, the third side wall and the fourth side wall are part of the second connecting piece, and the third side wall and the fourth side wall are located between the first side wall and the second side wall, by setting the minimum distance between the first side wall and the second side wall to be greater than the maximum distance between the third side wall and the fourth side wall, the contact between the first side wall, the second side wall, the third side wall and the fourth side wall can be more reliable through the deformation of the first side wall, the second side wall, the third side wall and the fourth side wall during assembly, thereby ensuring the connection reliability of the first connecting piece and the second connecting piece.

[0023] In some possible implementation manners, the first side wall is provided with a second protrusion on the side facing the second side wall, and the second protrusion abuts against the third side wall. And / or, the second side wall is provided with a third protrusion on the side facing the first side wall, and the third protrusion abuts against the fourth side wall.

[0024] In the examples of the present application, the first side wall is part of the first connecting piece, and the third side wall is part of the second connecting piece. By providing the second protrusion on the side of the first side wall facing the second side wall, and the second protrusion can abut against the third side wall. During the connection of the first connecting piece and the second connecting piece, the second protrusion can reduce the gap between the first side wall and the third side wall, so that the abutment of the third side wall and the first side wall is more reliable, thereby making the abutment of the first connecting piece and the second connecting piece more reliable.

[0025] The second side wall is part of the first connecting piece, and the fourth side wall is part of the second connecting piece. By providing the third protrusion on the side of the second side wall facing the first side wall, and the third protrusion can abut against the fourth side wall. During the connection of the first connecting piece and the second connecting piece, the third protrusion can reduce the gap between the second side wall and the fourth side wall, so that the abutment of the fourth side wall and the second side wall is more reliable, thereby making the abutment of the first connecting piece and the second connecting piece more reliable.

[0026] In some possible implementation manners, the first connecting piece comprises an insertion opening, the insertion opening is in communication with the mounting hole, and in the case that the first side wall is provided with the second protrusion on the side facing the second side wall, the first side wall is provided with a first guide surface and a second guide surface on the side facing the second side wall, the first guide surface is arranged on the side of the second protrusion close to the insertion opening, the inclination direction of the first guide surface is adapted to the direction of the second connecting piece inserted into the first connecting piece, and the inclination direction of the second guide surface is adapted to the direction of the second connecting piece separated from the first connecting piece.

[0027] In the example of the present application, the first guide surface is arranged on the second protrusion in a direction away from the insertion opening, and the inclination direction of the first guide surface is adapted to the direction in which the second connecting piece is separated from the first connecting piece. Based on this, in the separation process of the second connecting piece and the first connecting piece, the second connecting piece can gradually move from the position with the largest size between the first side wall and the second side wall to the position with the smallest size between the first side wall and the second side wall, and finally be separated from the first connecting piece. This can reduce the friction in the process of separating the second connecting piece from the first connecting piece, reduce the possibility of wear caused by the second connecting piece in the process of being separated from the first connecting piece, and improve the efficiency of separating the second connecting piece from the first connecting piece.

[0028] In the example of the present application, the first guide surface is arranged on the second protrusion in a direction away from the insertion opening, and the inclination direction of the first guide surface is adapted to the direction in which the second connecting piece is separated from the first connecting piece. Based on this, in the separation process of the second connecting piece and the first connecting piece, the second connecting piece can gradually move from the position with the largest size between the first side wall and the second side wall to the position with the smallest size between the first side wall and the second side wall, and finally be separated from the first connecting piece. This can reduce the friction in the process of separating the second connecting piece from the first connecting piece, reduce the possibility of wear caused by the second connecting piece in the process of being separated from the first connecting piece, and improve the efficiency of separating the second connecting piece from the first connecting piece.

[0029] In some possible implementation manners, the accessory body further comprises a bending segment, one end of the bending segment is fixedly connected with the first side wall, the other end of the bending segment is connected with the second terminal board, the thickness of the bending segment is less than the thickness of the first side wall, and the thickness of the bending segment is less than the thickness of the second terminal board.

[0030] In the example of the present application, since the first side wall is part of the first connecting piece, by arranging the one end of the bending segment to be connected with the first side wall and the other end of the bending segment to be connected with the second terminal board, the connection between the first connecting piece and the second terminal board can be realized. By arranging the thickness of the bending segment to be less than the thickness of the first side wall and the thickness of the bending segment to be less than the thickness of the second terminal board, the deformation amount of the bending segment can be increased, and thus the movement range of the first side wall relative to the second terminal board is increased, and the connection reliability of the first connecting piece and the second connecting piece is further ensured.

[0050] For example, this application provides a switch component, please refer to Figures 1-5 The switch assembly 100 includes a switch body 200 and a wiring accessory 300. The switch body 200 includes a first housing 210 and a first terminal block 220. The first terminal block 220 is fixedly installed inside the first housing 210. The first housing 210 is provided with a first inlet 211. The position of the first terminal block 220 corresponds to the position of the first inlet 211. The wiring accessory 300 includes a second housing 340 and a second terminal block 330. The second housing 340 is detachably connected to the first housing 210. The side wall of the second housing 340 is provided with a second inlet port 3221. An external wire extends into the second housing 340 from the second inlet port 3221 and is electrically connected to the second terminal block 330. The position of the second terminal block 330 corresponds to the position of the first inlet port 211. At least a portion of the second terminal block 330 is located outside the second housing 340, and the second terminal block 330 located in the second housing 340 can extend into the interior of the first housing 210 from the first inlet port 211 and elastically abut against the first terminal block 220.

[0051] The switch body 200 can be a circuit breaker, relay, disconnector, contactor, or other switching device that can control the opening and closing of a circuit, making it convenient for operators to maintain and repair the circuit and providing safety protection for the circuit. In this application, the example of the switch body 200 being a circuit breaker is used for description only.

[0052] The circuit breaker can be a single-pole circuit breaker or a multi-pole circuit breaker. Taking a single-pole circuit breaker as an example, each of the two ends of the single-pole circuit breaker is provided with a first inlet port 211. Each first inlet port 211 is provided with a first terminal block 220. The wiring accessory 300 can be electrically connected to both first terminal blocks 220 of the single-pole circuit breaker at the same time, so as to move the position of the single-pole circuit breaker and the external wires from the first housing 210 to the second housing 340 of the wiring accessory 300.

[0053] The switch body 200 comprises a first shell 210 and a first terminal block 220 fixedly installed in the first shell 210. The first shell 210 is provided with a first wire inlet 211, and the first terminal block 220 is arranged at a position corresponding to the position of the first wire inlet 211. The second terminal block 330 can be inserted into the first shell 210 from the first wire inlet 211 to be electrically connected with the first terminal block 220, thereby realizing the electrical connection between the second terminal block 330 and the switch body 200. Alternatively, an external wire can also be inserted into the first shell 210 from the first wire inlet 211 to be electrically connected with the first terminal block 220, thereby realizing the electrical connection between the external wire and the switch body 200. In this way, the electrical connection between the switch assembly 100 and the external wire can be realized in various modes to meet different customer requirements.

[0054] The switch body 200 further comprises an adjusting screw movably installed in the first shell 210. Along the movement direction of the adjusting screw in the first shell 210, the first terminal block 220 can be provided with a first conductive member and a second conductive member on two sides thereof, respectively. The second terminal block 330 can be located between the first terminal block 220 and the first conductive member, or between the first terminal block 220 and the second conductive member. The first conductive member and the second conductive member cooperate with other structures to form a terminal frame connected with the adjusting screw, so that the adjusting screw drives the terminal frame to move. Taking the case where the second terminal block 330 is located between the first conductive member and the first terminal block 220 as an example, the adjusting screw drives the terminal frame to move, thereby adjusting the distance between the first conductive member and the first terminal block 220, so that the first conductive member cooperates with the first terminal block 220 to clamp the second terminal block 330, thereby ensuring the cooperation reliability of the first terminal block 220 and the second terminal block 330.

[0055] The second terminal block 330 is part of the terminal accessory 300, and is arranged at a position corresponding to the position of the first wire inlet 211, so that the second terminal block 330 can be inserted into the first shell 210 from the first wire inlet 211 to be electrically connected with the first terminal block 220, thereby realizing the electrical connection between the terminal accessory 300 and the switch body 200.

[0056] The second wiring board 330 elastically abuts against the first wiring board 220, that is, in the state that the second wiring board 330 contacts the first wiring board 220, the second wiring board 330 can apply an acting force towards the first wiring board 220 to the first wiring board 220, or the first wiring board 220 applies an acting force towards the second wiring board 330 to the second wiring board 330, to ensure the contact reliability of the first wiring board 220 and the second wiring board 330. Specifically, a protrusion can be arranged on the side of the second wiring board 330 towards the first wiring board 220, and / or a protrusion can be arranged on the side of the first wiring board 220 towards the second wiring board 330, to realize the elastic abutment of the second wiring board 330 and the first wiring board 220. Alternatively, when the second wiring board 330 does not contact the first wiring board 220, the projection of the second wiring board 330 along the direction towards the first wiring board 220 partially overlaps the projection of the first wiring board 220, based on which, after the second wiring board 330 contacts the first wiring board 220, the elastic abutment of the second wiring board 330 and the first wiring board 220 can be realized through the elastic deformation of the second wiring board 330.

[0057] The position of the elastic abutment of the second wiring board 330 and the first wiring board 220 can be provided with only one or multiple, which is not specifically limited in the examples of the present application.

[0058] The materials of the second wiring board 330 and the first wiring board 220 can be the same or different. Taking the second wiring board 330 as an example, the second wiring board 330 can be made of beryllium copper, phosphor bronze or other materials that can conduct electricity and have a certain elastic ability, to ensure the reliability of the elastic abutment of the second wiring board 330 and the first wiring board 220, and reduce the possibility of damage of the second wiring board 330 and the first wiring board 220 due to large deformation.

[0104] In addition, since the first sub-housing 312 and the first connecting piece 311 are both parts of the accessory body 310, and the second sub-housing 322 and the second connecting piece 321 are both parts of the base 320, the detachable connection between the accessory body 310 and the base 320 can be realized by the detachable connection between the first sub-housing 312 and the second sub-housing 322, and the detachable connection between the first connecting piece 311 and the second connecting piece 321, so as to detachably connect the switch body 200 and the accessory body 310 as a whole with the base 320 during the maintenance or repair of the switch assembly 100, and avoid the removal of the external lead wire corresponding to the single switch body 200, thereby reducing the labor cost caused by maintenance or repair in the use of the switch assembly 100.

[0105] Based on the switch assembly 100 provided in the above example, please refer to Figure 3 and Figure 6The first connector 311 includes a first sidewall 3111 and a second sidewall 3112 disposed opposite to each other, and the second connector 321 includes a third sidewall and a fourth sidewall disposed opposite to each other. The third sidewall and the fourth sidewall are installed between the first sidewall 3111 and the second sidewall 3112. The minimum distance between the first sidewall 3111 and the second sidewall 3112 is less than the maximum distance between the third sidewall and the fourth sidewall.

[0106] The first sidewall 3111 and the second sidewall 3112 can be spaced apart. The first sidewall 3111 and the second sidewall 3112 can also be connected by other structures, as long as there is enough space between the first sidewall 3111 and the second sidewall 3112 for the second connector 321 to connect with the first connector 311.

[0107] The second connector 321 includes a third sidewall and a fourth sidewall. The third sidewall and the fourth sidewall can be spaced apart. The third sidewall and the fourth sidewall can be two sidewalls arranged opposite each other on two plate-like structures, or they can be two sidewalls arranged opposite each other on the same plate-like structure.

[0108] The minimum distance between the first sidewall 3111 and the second sidewall 3112 is less than the maximum distance between the third sidewall and the fourth sidewall, which can be achieved by setting a protrusion in at least one of the first sidewall 3111 and the second sidewall 3112.

[0109] In this example, since the first sidewall 3111 and the second sidewall 3112 are both part of the first connector 311, and the third sidewall and the fourth sidewall are both part of the second connector 321, and the third sidewall and the fourth sidewall are located between the first sidewall 3111 and the second sidewall 3112, by setting the minimum distance between the first sidewall 3111 and the second sidewall 3112 to be greater than the maximum distance between the third sidewall and the fourth sidewall, the deformation generated by the first sidewall 3111, the second sidewall 3112, the third sidewall, and the fourth sidewall during the assembly process can make the contact of the first sidewall 3111, the second sidewall 3112, the third sidewall, and the fourth sidewall more reliable, thereby ensuring the connection reliability of the first connector 311 and the second connector 321.

[0110] Based on the switch component 100 provided in the above example, please refer to Figure 3 and Figure 6 The first sidewall 3111 has a second protrusion on the side facing the second sidewall 3112, and the second protrusion abuts against the third sidewall. And / or, the second sidewall 3112 has a third protrusion on the side facing the first sidewall 3111, and the third protrusion abuts against the fourth sidewall.

[0111] The second protrusion can be a protruding structure such as a bump, a protruding strip, a protruding column, etc. provided on the first side wall 3111. The second protrusion can also be a protruding structure formed by bending the second side wall 3112.

[0112] The third protrusion can be fixedly provided on the second side wall 3112, or can be movable relative to the second side wall 3112. Specifically, the second side wall 3112 can include a side wall body and a second setting portion. The second setting portion is provided with the second protrusion on one side facing the first side wall 3111. One end of the second setting portion is fixedly connected to the side wall body, and the other end of the second setting portion is a free end, so as to realize the movability of the second protrusion relative to the second side wall 3112.

[0113] In the case where the second side wall 3112 includes the side wall body and the second setting portion, the second sub-housing 322 is provided with a clamping groove corresponding to the position of the side wall body, and the clamping groove is used to clamp the side wall body close to the free end of the second setting portion, so as to ensure the connection reliability of the second connecting piece 321 and the second sub-housing 322.

[0114] Based on the above, the second protrusion can be provided only on one side of the first side wall 3111 facing the second side wall 3112, or the third protrusion can be provided only on one side of the second side wall 3112 facing the first side wall 3111, or the second protrusion can be provided on one side of the first side wall 3111 facing the second side wall 3112, and the third protrusion can be provided on one side of the second side wall 3112 facing the first side wall 3111. The present application does not make specific limitations on this.

[0115] In the present application, the first side wall 3111 is part of the first connecting piece 311, and the third side wall is part of the second connecting piece 321. By providing the second protrusion on one side of the first side wall 3111 facing the second side wall 3112, and the second protrusion can abut to the third side wall. In the connection process of the first connecting piece 311 and the second connecting piece 321, the second protrusion can reduce the gap between the first side wall 3111 and the third side wall, so that the abutment of the third side wall and the first side wall 3111 is more reliable, and thus the abutment of the first connecting piece 311 and the second connecting piece 321 is more reliable.

[0116] The second side wall 3112 is part of the first connecting piece 311, and the fourth side wall is part of the second connecting piece 321. By providing the third protrusion on one side of the second side wall 3112 facing the first side wall 3111, and the third protrusion can abut to the fourth side wall. In the connection process of the first connecting piece 311 and the second connecting piece 321, the third protrusion can reduce the gap between the second side wall 3112 and the fourth side wall, so that the abutment of the fourth side wall and the second side wall 3112 is more reliable, and thus the abutment of the first connecting piece 311 and the second connecting piece 321 is more reliable.

[0117] Based on the switch assembly 100 provided in the above example, please refer to Figure 6 The first connecting piece 311 includes an insertion port 3113 which is in communication with the mounting hole. In the case that the first side wall 3111 has the second protrusion on the side facing the second side wall 3112, the first side wall 3111 has a first guide surface and a second guide surface on the side facing the second side wall 3112. The first guide surface is arranged on the side of the second protrusion close to the insertion port 3113. The inclination direction of the first guide surface is adapted to the direction in which the second connecting piece 321 is inserted into the first connecting piece 311. The inclination direction of the second guide surface is adapted to the direction in which the second connecting piece 321 is separated from the first connecting piece 311.

[0118] The first side wall 3111 and the second side wall 3112 cooperate to form the insertion port 3113 which is in communication with the mounting hole, so that the second connecting piece 321 can be sequentially arranged in the mounting hole and the insertion port 3113 to be connected with the first connecting piece 311.

[0119] Whether the second protrusion is arranged only on the first side wall 3111 or the second protrusion is arranged on the first side wall 3111 and a third protrusion is arranged on the second side wall 3112, both belong to the case that the second protrusion is arranged on the side of the first side wall 3111 facing the second side wall 3112. At this time, at least one of the first guide surface and the second guide surface can be arranged on the first side wall 3111. The included angle between the first guide surface and the first side wall 3111 is greater than 10 degrees and less than or equal to 30 degrees. Similarly, the included angle between the second guide surface and the first side wall 3111 is greater than 10 degrees and less than or equal to 30 degrees, so as to improve the assembly efficiency of the second connecting piece 321 and the first connecting piece 311.

[0120] In the example of the present application, the first guide surface is arranged on the side of the second protrusion close to the insertion port 3113, and the inclination direction of the first guide surface is adapted to the direction in which the second connecting piece 321 is inserted into the first connecting piece 311. Based on this, in the assembly process of the second connecting piece 321 and the first connecting piece 311, the second connecting piece 321 can first extend into the position with the largest size in the first side wall 3111 and the second side wall 3112, so as to improve the assembly efficiency of the second connecting piece 321 and the first connecting piece 311.

[0121] By arranging the second guide surface in a direction in which the second protrusion is away from the insertion opening 3113, and the inclination direction of the second guide surface is adapted to the direction in which the second connecting piece 321 is separated from the first connecting piece 311, based on this, in the assembly process of the second connecting piece 321 and the first connecting piece 311, the second connecting piece 321 can gradually move from the position with the largest size between the first side wall 3111 and the second side wall 3112 to the position with the smallest size between the first side wall 3111 and the second side wall 3112, and finally separated from the first connecting piece 311, which can reduce the friction in the process of separating the second connecting piece 321 from the first connecting piece 311, reduce the possibility of wear caused by the second connecting piece 321 in the process of separating from the first connecting piece 311, and improve the efficiency of separating the second connecting piece 321 from the first connecting piece 311.

[0122] Based on the above, in the case that the second side wall 3112 is provided with a third protrusion on the side facing the first side wall 3111, the second side wall 3112 is provided with a third guide surface and a fourth guide surface on the side facing the first side wall 3111, the third guide surface is arranged on the side of the third protrusion close to the insertion opening 3113, the inclination direction of the third guide surface is adapted to the direction of the second connecting piece 321 inserted into the first connecting piece 311, and the inclination direction of the fourth guide surface is adapted to the direction of the second connecting piece 321 separated from the first connecting piece 311.

[0123] The function of the third guide surface is similar to that of the first guide surface, and the function of the fourth guide surface is similar to that of the second guide surface, which will not be described in detail in this example.

[0124] Based on the switch assembly 100 provided in the above example, please refer to Figure 6 The accessory body 310 further comprises a bent segment 313, one end of the bent segment 313 is fixedly connected with the first side wall 3111, the other end of the bent segment 313 is connected with the second connecting plate 330, the thickness of the bent segment 313 is smaller than the thickness of the first side wall 3111, and the thickness of the bent segment 313 is smaller than the thickness of the second connecting plate 330.

[0125] The bent segment 313 can be fixedly connected with the first connecting piece 311 and the second connecting plate by welding or the like, and the bent segment 313 can also be integrally formed with the first connecting piece 311 and the second connecting plate 330, which will not be specifically limited in this example.

[0126] The bent segment 313 is an arc-shaped structure formed by bending, based on this, the thickness of the bent segment 313 refers to the size in the direction corresponding to the circle of the arc-shaped structure.

[0127] The thickness of the first side wall 3111 refers to the size of the first side wall 3111 in the direction facing the second side wall 3112.

[0128] The thickness of the second wiring board 330 refers to the size of the second wiring board 330 in a direction from the first wiring board 220 to the second wiring board 330 when the first wiring board 220 and the second wiring board 330 elastically abut against each other.

[0129] The thickness of the first side wall 3111 can be equal to or different from the thickness of the second wiring board 330. For example, when the thickness of the first side wall 3111 is equal to the thickness of the second wiring board 330, the thickness of the bending segment 313 can be less than or equal to 95% of the thickness of the first side wall 3111 and greater than or equal to 50% of the thickness of the first side wall 3111. The present application does not limit the relationship between the thickness of the bending segment 313 and the thickness of the first side wall 3111 and the thickness of the second wiring board 330, as long as the reliability of the bending segment 313 is ensured.

[0130] In the present application, since the first side wall 3111 is part of the first connecting member 311, the first connecting member 311 and the second wiring board 330 can be connected by connecting one end of the bending segment 313 to the first side wall 3111 and connecting the other end of the bending segment 313 to the second wiring board 330. By setting the thickness of the bending segment 313 to be less than the thickness of the first side wall 3111 and the thickness of the second wiring board 330, the deformation amount of the bending segment 313 can be increased, and the movement range of the first side wall 3111 relative to the second wiring board 330 can be increased, thereby further ensuring the connection reliability of the first connecting member 311 and the second connecting member 321.

[0131] Finally, it should be noted that the above embodiments are merely specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
