Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more particularly to a switching assembly. Background Technology

[0002] Switching assemblies control the on / off state of circuits, ensuring circuit safety and reducing the possibility of faults escalating. A switching assembly includes a matching switch body and wiring accessories; the switch body can be a circuit breaker, relay, or other switching device.

[0003] Based on the existing structure of switch assemblies, the switch body is usually connected to the wiring accessories by threads, which makes the assembly efficiency of the switch body and wiring accessories low, resulting in a high cost of use when inspecting and maintaining the switch assembly. Summary of the Invention

[0004] This application provides a switch assembly that can improve the assembly efficiency of the switch body and wiring accessories, thereby reducing labor costs in the inspection and maintenance process of the switch assembly and reducing the cost of using the switch assembly.

[0005] In a first aspect, this 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 terminal block, the first terminal block being fixedly installed inside the first housing. The first housing has a first wire inlet, and the position of the first terminal block corresponds to the position of the first wire inlet. The wiring accessory includes a second housing and a second terminal block, the second housing being detachably connected to the first housing. The side wall of the second housing has a second wire inlet, an external wire extending into the second housing from the second wire inlet and electrically connecting to the second terminal block. The position of the second terminal block corresponds to the position of the first wire inlet, at least a portion of the second terminal block is located outside the second housing, and the second terminal block located outside the second housing can extend into the interior of the first housing from the first wire inlet and elastically abut against the first terminal block.

[0006] In this application example, the switch body and wiring accessories are detachably connected. The first terminal block and the first housing are part of the switch body, and the second terminal block and the second housing are part of the wiring accessories. The first housing has a first inlet. The positions of the first terminal block and the second terminal block correspond to the positions of the first inlet. A portion of the second terminal block is located outside the second housing, and this portion can extend into the first housing from the first inlet and elastically abut against the first terminal block to achieve electrical connection between the wiring accessories and the switch body. Compared to the prior art, which uses a threaded connection to achieve electrical connection between the wiring accessories and the switch body, in this application example, by having the second terminal block extend into the first housing and elastically abut against the first terminal block, electrical connection between the wiring accessories and the switch body can be achieved. This simplifies the electrical connection method, improves the assembly efficiency of the wiring accessories and the switch body, and reduces the cost of using the switch assembly.

[0007] Furthermore, compared to achieving electrical connection between the wiring accessory and the switch body via threaded connection, in this application example, the deformation of the first and second terminal blocks allows them to elastically abut against each other. This avoids situations where the wiring accessory and the switch body experience incomplete contact due to thread stripping or insufficient torque. This ensures reliable contact between the first and second terminal blocks, thereby guaranteeing reliable connection between the wiring accessory and the switch body.

[0008] In some possible implementations, the first terminal block includes a first sub-block and a second sub-block connected together. The first sub-block is substantially parallel to the direction in which the second terminal block extends into the first inlet, and the second sub-block is substantially perpendicular to the first sub-block, located on the side of the first sub-block away from the first inlet. The second terminal block includes a third sub-block and a fourth sub-block connected together. The third sub-block extends from the first inlet into the first housing and elastically abuts against the first sub-block, with at least one position where the third sub-block elastically abuts against the first sub-block. The fourth sub-block is substantially perpendicular to the third sub-block and elastically abuts against the second sub-block.

[0009] In this example, the first and second sub-boards are both part of the first terminal block, and the third and fourth sub-boards are both part of the second terminal block. The third sub-board is elastically abutted against the first sub-board, and the fourth sub-board is elastically abutted against the second sub-board. Since the second sub-board is substantially perpendicular to the first sub-board, and the fourth sub-board is substantially perpendicular to the third sub-board, the positions where the third sub-board elastically abuts against the first sub-board and the fourth sub-board elastically abuts against the second sub-board are located on different planes. The positions where the third sub-board elastically abuts against the first sub-board are independent of the positions where the fourth sub-board elastically abuts against the second sub-board can reduce the possibility of mutual interference between the positions where the third sub-board elastically abuts against the first sub-board and the fourth sub-board elastically abuts against the second sub-board, ensuring the contact reliability of the first terminal block and the second terminal block, and thus ensuring the reliability of the switch assembly.

[0010] In some possible implementations, the third plate has at least one first protrusion on the side facing the first plate, and the first protrusion elastically abuts against the first plate on the side facing the first plate.

[0011] In this application example, by providing at least one first protrusion on the side of the third sub-plate facing the first sub-plate, the first protrusion can abut against the first sub-plate when the first terminal block and the second terminal block are in elastic contact, making the contact between the first protrusion and the first sub-plate more reliable, increasing the effective contact area between the third sub-plate and the first sub-plate, ensuring the contact reliability between the first terminal block and the second terminal block, and thus ensuring the reliability of the switch assembly.

[0012] In some possible implementations, the first partition plate has a plurality of first grooves spaced apart on the side facing the third partition plate, and the first partition plate between two adjacent first grooves serves as a first contact surface, with at least a portion of the first contact surface elastically abutting against the third partition plate. And / or, the third partition plate has a plurality of second grooves spaced apart on the side facing the first partition plate, and the third partition plate between two adjacent second grooves serves as a second contact surface, with at least a portion of the second contact surface elastically abutting against the first partition plate.

[0013] In this application example, when multiple first grooves are provided at intervals on the side of the first sub-plate facing the third sub-plate, the multiple first grooves divide the side of the first sub-plate facing the third sub-plate into multiple spaced first contact surfaces. The first contact surfaces elastically abut against the third sub-plate, which can reduce the possibility of different first contact surfaces affecting each other, thereby increasing the effective contact area between the first sub-plate and the third sub-plate and ensuring the contact reliability between the first sub-plate and the third sub-plate.

[0014] When multiple second grooves are provided at intervals on the side of the third plate facing the first plate, the multiple second grooves divide the side of the third plate facing the first plate into multiple spaced second contact surfaces. The second contact surfaces elastically abut against the first plate, which can reduce the possibility of different second contact surfaces affecting each other, thereby increasing the effective contact area between the third plate and the first plate and ensuring the contact reliability between the third plate and the first plate.

[0015] In some possible implementations, the first terminal block further includes a fifth sub-board, which is located at the end of the second sub-board opposite to the first sub-board and on the side of the second sub-board facing the first inlet. The second terminal block also includes a sixth sub-board, which is located at the end of the fourth sub-board opposite to the third sub-board and, along the direction in which the second terminal block extends into the first inlet, is located on the same side of the fourth sub-board as the third sub-board. The maximum distance between the sixth sub-board and the third sub-board is less than the minimum distance between the fifth sub-board and the first sub-board, and the fifth sub-board and the sixth sub-board are elastically abutted against each other.

[0016] In this example, the fifth sub-board is part of the first terminal block and is located at the end of the second sub-board away from the first sub-board. The sixth sub-board is part of the second terminal block and is located at the end of the first sub-board away from the third sub-board. Therefore, the contact position between the sixth and fifth sub-boards is independent of the contact position between the first and third sub-boards, and also independent of the contact position between the second and fourth sub-boards. This reduces the possibility of mutual interference between the contact positions of the sixth and fifth sub-boards and the contact positions of the first and third sub-boards, as well as the contact positions of the second and fourth sub-boards, thus ensuring the reliability of the contact between the first and second terminal blocks.

[0017] Furthermore, since the maximum distance between the sixth and third sub-boards is less than the maximum distance between the fifth and first sub-boards, the contact reliability between the sixth and fifth sub-boards and between the third and first sub-boards can be further guaranteed, as can the contact reliability between the first and second terminal boards.

[0018] In some possible implementations, the second housing includes a first sub-housing and a second sub-housing, and the wiring accessory includes an accessory body and a base. The accessory body also includes a first connector and the first sub-housing. The side wall of the first sub-housing has a mounting hole. The first connector is fixedly installed inside the first sub-housing, and the position of the first connector corresponds to the position of the mounting hole. The first sub-housing and the first housing are detachably connected. The first connector is fixedly connected to a second terminal block, and at least part of the second terminal block is located outside the first sub-housing. The base includes a fixedly connected second connector and a second sub-housing. The second sub-housing and the first sub-housing are detachably connected. The second connector, extending into the second sub-housing, extends into the first sub-housing from the mounting hole and is detachably connected to the first connector. The side wall of the second sub-housing has a second cable inlet.

[0019] In this example, since the first connector is part of the accessory body, and both the accessory body and the second terminal block are part of the wiring accessory, and the second terminal block is connected to the switch body, the electrical connection between the accessory body and the switch body can be achieved through the fixed connection between the first connector and the second terminal block. Based on this, the external wire is connected to the accessory body via the base, and can then be connected to the switch body via the accessory body, thereby achieving the connection between the external wire and the switch body.

[0020] Furthermore, since the first sub-shell and the first connector are both part of the accessory body, and the second sub-shell and the second connector are both part of the base, the detachable connection between the first sub-shell and the second sub-shell, and the detachable connection between the first connector and the second connector, can achieve a detachable connection between the accessory body and the base. This allows the switch body and the accessory body to be detachably connected to the base as a whole during the maintenance or repair of the switch assembly, avoiding the need to remove the external wires corresponding to a single switch body, thereby reducing the labor costs incurred during the maintenance or repair of the switch assembly.

[0021] In some possible implementations, the first connector includes a first sidewall and a second sidewall disposed opposite to each other, and the second connector 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 and the second sidewall, and the minimum distance between the first sidewall and the second sidewall is less than the maximum distance between the third sidewall and the fourth sidewall.

[0022] In this example, since the first and second sidewalls are both part of the first connector, and the third and fourth sidewalls are both part of the second connector, and the third and fourth sidewalls are located between the first and second sidewalls, by setting the minimum distance between the first and second sidewalls to be greater than the maximum distance between the third and fourth sidewalls, the deformation of the first, second, third, and fourth sidewalls during assembly can ensure reliable contact between them, thereby guaranteeing the connection reliability between the first and second connectors.

[0023] In some possible implementations, the first sidewall has a second protrusion on the side facing the second sidewall, and the second protrusion abuts against the third sidewall. And / or, the second sidewall has a third protrusion on the side facing the first sidewall, and the third protrusion abuts against the fourth sidewall.

[0024] In this application example, the first sidewall is part of the first connector, and the third sidewall is part of the second connector. A second protrusion is provided on the side of the first sidewall facing the second sidewall, and the second protrusion can abut against the third sidewall. During the connection process between the first connector and the second connector, the second protrusion can reduce the gap between the first sidewall and the third sidewall, making the abutment between the third sidewall and the first sidewall more reliable, thereby making the abutment between the first connector and the second connector more reliable.

[0025] The second sidewall is part of the first connector, and the fourth sidewall is part of the second connector. A third protrusion is provided on the side of the second sidewall facing the first sidewall, and the third protrusion can abut against the fourth sidewall. During the connection process between the first connector and the second connector, the third protrusion can reduce the gap between the second sidewall and the fourth sidewall, making the abutment between the fourth sidewall and the second sidewall more reliable, thereby making the abutment between the first connector and the second connector more reliable.

[0026] In some possible implementations, the first connector includes an insertion port that communicates with a mounting hole. If a second protrusion is provided on the side of the first sidewall facing the second sidewall, a first guide surface and a second guide surface are provided on the side of the first sidewall facing the second sidewall. The first guide surface is located on the side of the second protrusion near the insertion port. The inclination direction of the first guide surface is adapted to the direction in which the second connector is inserted into the first connector, and the inclination direction of the second guide surface is adapted to the direction in which the second connector is disengaged from the first connector.

[0027] In this application example, by setting a first guide surface in the direction of the second protrusion near the insertion port, and the tilt direction of the first guide surface is adapted to the direction of the second connector being inserted into the first connector, based on this, during the assembly process of the second connector and the first connector, the second connector can be inserted first into the position with the largest size between the first sidewall and the second sidewall, which can improve the assembly efficiency of the second connector and the first connector.

[0028] By setting a second guide surface in the direction away from the insertion port of the second protrusion, and the inclination direction of the second guide surface is adapted to the direction in which the second connector separates from the first connector, based on this, during the process of the second connector separating from the first connector, the second connector can gradually move from the position with the largest size between the first sidewall and the second sidewall to the position with the smallest size between the first sidewall and the second sidewall, and finally separate from the first connector. This can reduce the frictional force during the process of the second connector separating from the first connector, reduce the possibility of wear caused by the second connector during the process of separating from the first connector, and improve the efficiency of the second connector separating from the first connector.

[0029] In some possible implementations, the accessory body also includes a bent section, one end of which is fixedly connected to the first sidewall, and the other end of which is connected to the second terminal block. The thickness of the bent section is less than the thickness of the first sidewall and less than the thickness of the second terminal block.

[0030] In this example, since the first sidewall is part of the first connector, the connection between the first connector and the second terminal block can be achieved by connecting one end of the bent section to the first sidewall and the other end of the bent section to the second terminal block. By setting the thickness of the bent section to be less than the thickness of the first sidewall and less than the thickness of the second terminal block, the deformation of the bent section can be increased, thereby increasing the range of motion of the first sidewall relative to the second terminal block, further ensuring the reliability of the connection between the first connector and the second connector.

[0049] Figure 1 This application provides a schematic diagram of the structure of a switch assembly. Figure 2 This application provides a schematic diagram of the structure of a partial switch assembly. Figure 3 for Figure 2Sectional view at point AA. Figure 4 This application provides a schematic diagram of the structure of a switch body as an example. Figure 5 for Figure 4 Sectional view at point BB.

[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 includes a first housing 210 and a first terminal block 220, with the first terminal block 220 fixedly installed inside the first housing 210. The first housing 210 has a first inlet port 211, and the position of the first terminal block 220 corresponds to the position of the first inlet port 211. A second terminal block 330 can extend into the first housing 210 from the first inlet port 211 and be electrically connected to the first terminal block 220, thus realizing the electrical connection between the second terminal block 330 and the switch body 200. Alternatively, an external wire can also extend into the first housing 210 from the first inlet port 211 and be electrically connected to the first terminal block 220, thus realizing the electrical connection between the external wire and the switch body 200. This enriches the ways in which the switch assembly 100 can be electrically connected to external wires to meet different customer needs.

[0054] The switch body 200 also includes an adjusting screw, which is movably mounted to the first housing 210. Along the direction of movement of the adjusting screw within the first housing 210, a first conductive element and a second conductive element can be respectively provided on both sides of the first terminal block 220. The second terminal block 330 can be located between the first terminal block 220 and the first conductive element, or it can be located between the first terminal block 220 and the second conductive element. The first and second conductive elements, in conjunction with other structures, can form a wiring frame. The wiring frame is connected to the adjusting screw, so that the adjusting screw drives the wiring frame to move. Taking the second terminal block 330 located between the first conductive element and the first terminal block 220 as an example, the adjusting screw drives the wiring frame to move, which can adjust the distance between the first conductive element and the first terminal block 220, so that the first conductive element, in conjunction with the first terminal block 220, clamps the second terminal block 330, ensuring the reliable fit between the first terminal block 220 and the second terminal block 330.

[0055] The second terminal block 330 is part of the wiring accessory 300. The position of the second terminal block 330 corresponds to the position of the first inlet port 211, so that the second terminal block 330 can extend into the first housing 210 from the first inlet port 211 and be electrically connected to the first terminal block 220, thereby realizing the electrical connection between the wiring accessory 300 and the switch body 200.

[0056] The second terminal block 330 elastically abuts against the first terminal block 220. That is, when the second terminal block 330 is in contact with the first terminal block 220, the second terminal block 330 can apply a force toward the first terminal block 220, or the first terminal block 220 can apply a force toward the second terminal block 330, to ensure reliable contact between the two terminals. Specifically, this elastic abutment can be achieved by providing a protrusion on the side of the second terminal block 330 facing the first terminal block 220, and / or by providing a protrusion on the first terminal block 220 facing the second terminal block 330. Alternatively, when the second terminal block 330 is not in contact with the first terminal block 220, the projection of the second terminal block 330 in the direction from the second terminal block 330 to the first terminal block 220 coincides with the projection of the first terminal block 220. Based on this, after the second terminal block 330 comes into contact with the first terminal block 220, the elastic deformation of the second terminal block 330 can achieve elastic contact between the second terminal block 330 and the first terminal block 220.

[0057] The second terminal block 330 and the first terminal block 220 may have only one position that elastically abuts, or multiple positions may be provided at intervals. This application example does not impose specific restrictions on this.

[0058] The second terminal block 330 and the first terminal block 220 can be made of the same or different materials. Taking the second terminal block 330 as an example, the second terminal block 330 can be made of materials that are conductive and have a certain degree of elasticity, such as beryllium copper or phosphor bronze, to ensure the reliability of the elastic contact between the second terminal block 330 and the first terminal block 220 and reduce the possibility of damage to the second terminal block 330 and the first terminal block 220 due to large deformation.

[0059] The wiring accessory 300 also includes a second housing 340. The second wiring board 330 is fixedly installed to the second housing 340 by means of snap-fit, fusion connection, etc. The second housing 340 is detachably connected to the first housing 210. Exemplarily, the outer wall of the first housing 210 is provided with a mounting protrusion. The mounting protrusion can be an existing structure of the first housing 210, or it can be a specially designed structure. This application example does not specifically limit this. The second housing 340 is provided with a mounting groove corresponding to the mounting protrusion, or the outer wall of the first housing 210 is provided with a mounting groove, and the second housing 340 is provided with a mounting protrusion corresponding to the mounting groove. Whether the mounting protrusion is located in the first housing 210 and the mounting groove in the second housing 340, or vice versa, the detachable connection between the first housing 210 and the second housing 340 can be achieved through the cooperation of the mounting protrusion and the mounting groove. There may be one or more mounting protrusions, and the number of mounting grooves is equal to the number of mounting protrusions. The mounting grooves correspond one-to-one with the mounting protrusions. This application example does not impose specific limitations on this.

[0060] The second inlet port 3221 of the second housing 340 is specifically located on the side of the second housing 340 away from the first inlet port 211, so that the external wire can extend into the wiring accessory 300 and be electrically connected to the wiring accessory 300.

[0061] In this application example, the switch body 200 and the wiring accessory 300 are detachably connected. The first terminal block 220 and the first housing 210 are part of the switch body 200, and the second terminal block 330 and the second housing 340 are part of the wiring accessory 300. The first housing 210 is provided with a first inlet 211. The positions of the first terminal block 220 and the second terminal block 330 correspond to the positions of the first inlet 211. A portion of the second terminal block 330 is located outside the second housing 340, and this portion of the second terminal block 330 can extend from the first inlet 211 into the interior of the first housing 210 and elastically abut against the first terminal block 220 to achieve electrical connection between the wiring accessory 300 and the switch body 200. Compared to the prior art, which uses a threaded connection to achieve electrical connection between the wiring accessory and the switch body, in this application example, the second wiring plate 330 extends into the first housing 210 and elastically abuts against the first wiring plate 220, thereby achieving electrical connection between the wiring accessory 300 and the switch body 200. This makes the electrical connection method between the wiring accessory 300 and the switch body 200 simpler, improves the assembly efficiency of the wiring accessory 300 and the switch body 200, and reduces the cost of using the switch assembly 100.

[0062] Furthermore, compared to achieving electrical connection between the wiring accessory and the switch body via a threaded connection, in this application example, the deformation of the first terminal block 220 and the second terminal block 330 allows the first terminal block 220 and the second terminal block 330 to elastically abut against each other. This can prevent the wiring accessory from making incomplete contact with the switch body due to stripped threads or insufficient torque. This ensures the reliability of the contact between the first terminal block 220 and the second terminal block 330, thereby ensuring the reliability of the connection between the wiring accessory 300 and the switch body 200.

[0063] Based on the switch component 100 provided in the above example, please refer to Figures 1-5 The first terminal block 220 includes a first sub-block 221 and a second sub-block 222 connected together. The first sub-block 221 is substantially parallel to the direction in which the second terminal block 330 extends into the first inlet port 211, and the second sub-block 222 is substantially perpendicular to the first sub-block 221. The second sub-block 222 is located on the side of the first sub-block 221 away from the first inlet port 211. The second terminal block 330 includes a third sub-block 331 and a fourth sub-block 332 connected together. The third sub-block 331 extends from the first inlet port 211 into the first housing 210 and elastically abuts against the first sub-block 221. At least one position is provided where the third sub-block 331 elastically abuts against the first sub-block 221. The fourth sub-block 332 is substantially perpendicular to the third sub-block 331 and elastically abuts against the second sub-block 222.

[0064] The first sub-plate 221 and the second sub-plate 222 are part of the first terminal block 220. The first sub-plate 221 and the second sub-plate 222 can be fixedly connected by welding, riveting or other methods. The first sub-plate 221 and the second sub-plate 222 can also be integrally formed by stamping or other methods. The example in this application is only described using the integrally formed first sub-plate 221 and the second sub-plate 222 as an example.

[0065] The first branch plate 221 is basically parallel to the direction in which the second terminal plate 330 is inserted into the first inlet port 211. It can be understood that the angle formed between the first branch plate 221 and the direction in which the second terminal plate 330 is inserted into the first inlet port 211 is less than or equal to 5 degrees.

[0066] The second plate 222 is basically perpendicular to the first plate 221. It can be understood that the angle formed by the first plate 221 and the second plate 222 is less than or equal to 95 degrees and greater than or equal to 85 degrees.

[0067] The second dividing plate 222 is located on the side of the first dividing plate 221 opposite to the first inlet port 211. That is, during the process of the second connector 330 extending into the first housing 210 from the first inlet port 211, it will touch the second dividing plate 222. The second dividing plate 222 can limit the size of the second connector 330 extending into the first housing 210. The second dividing plate 222 can be located on the side of the first dividing plate 221 closer to the operating mechanism 230, or it can be located on the side of the first dividing plate 221 opposite to the operating mechanism 230.

[0068] The first sub-plate 221 may include only one plate-like structure, or it may include two plate-like structures. The second sub-plate 222 may include only one plate-like structure, or it may include two plate-like structures. The number of first sub-plates 221 and the number of second sub-plates 222 may be equal or unequal. This application does not impose specific restrictions on this.

[0069] The third sub-plate 331 and the fourth sub-plate 332 are part of the second terminal block 330. The third sub-plate 331 extends into the first housing 210 from the first inlet 211 and elastically abuts against the first sub-plate 221. When the second sub-plate 222 is located on the side of the first sub-plate 221 closer to the operating mechanism 230, the third sub-plate 331 elastically abuts against the side of the first sub-plate 221 closer to the operating mechanism 230. When the second sub-plate 222 is located on the side of the first sub-plate 221 away from the operating mechanism 230, the third sub-plate 331 elastically abuts against the side of the first sub-plate 221 away from the operating mechanism 230. The third sub-plate 331 can be a flat plate structure or a curved plate structure.

[0070] The fourth partition plate 332 is positioned corresponding to the second partition plate 222. When the second partition plate 222 is located on the side of the first partition plate 221 close to the operating mechanism 230, the fourth partition plate 332 is located on the side of the third partition plate 331 close to the operating mechanism 230. When the second partition plate 222 is located on the side of the first partition plate 221 away from the operating mechanism 230, the fourth partition plate 332 is located on the side of the third partition plate 331 away from the operating mechanism 230, so that the fourth partition plate 332 can elastically abut against the second partition plate 222.

[0071] The fourth plate 332 is basically perpendicular to the third plate 331. This can be understood as the angle formed by the fourth plate 332 and the third plate 331 being less than or equal to 95 degrees and greater than or equal to 85 degrees.

[0072] In this example, both the first sub-board 221 and the second sub-board 222 are part of the first terminal block 220, and both the third sub-board 331 and the fourth sub-board 332 are part of the second terminal block 330. The third sub-board 331 elastically abuts against the first sub-board 221, and the fourth sub-board 332 elastically abuts against the second sub-board 222. Since the second sub-board 222 is substantially perpendicular to the first sub-board 221, and the fourth sub-board 332 is substantially perpendicular to the third sub-board 331, the position where the third sub-board 331 elastically abuts against the first sub-board 221 and the fourth sub-board 332 are both part of the second terminal block 220. The positions where the split plate 332 elastically abuts against the second split plate 222 are located on different planes. The position where the third split plate 331 elastically abuts against the first split plate 221 is independent of the position where the fourth split plate 332 elastically abuts against the second split plate 222. This can reduce the possibility of mutual interference between the positions where the third split plate 331 elastically abuts against the first split plate 221 and the positions where the fourth split plate 332 elastically abuts against the second split plate 222, ensuring the contact reliability between the first terminal block 220 and the second terminal block 330, and thus ensuring the reliability of the switch assembly 100.

[0073] Based on the switch component 100 provided in the above example, Figure 6 A schematic diagram illustrating the mating of the second terminal block and the first connector, as provided in this application, is shown below. Figures 3-6 The third sub-plate 331 has at least one first protrusion 3311 on the side facing the first sub-plate 221, and the side of the first protrusion 3311 facing the first sub-plate 221 elastically abuts against the first sub-plate 221.

[0074] The first protrusion 3311 can be a protruding structure such as a protruding strip, protruding point, or protruding column provided on the third sub-plate 331. The first protrusion 3311 can also be a protruding structure formed by bending the first sub-plate 221. There can be only one first protrusion 3311, or there can be multiple first protrusions 3311 spaced apart. This application example does not make specific restrictions on this.

[0075] The first protrusion 3311 can be a protrusion structure fixedly disposed on the third sub-plate 331, and the first protrusion 3311 can also be movable relative to the third sub-plate 331. When the first protrusion 3311 is movable relative to the third sub-plate 331, the third sub-plate 331 can include a sub-plate body and a first mounting part. One end of the first mounting part is fixedly connected to the sub-plate body, and the other end of the first mounting part is a free end. The first protrusion 3311 is disposed on the first mounting part. By setting the end of the first mounting part to be a free end and the first protrusion 3311 to be disposed on the first mounting part, the range of motion of the first protrusion 3311 relative to the sub-plate body can be increased, thereby reducing the possibility of damage to the third sub-plate 331 due to large deformation.

[0076] In this application example, by providing at least one first protrusion 3311 on the side of the third sub-plate 331 facing the first sub-plate 221, the first protrusion 3311 can abut against the first sub-plate 221 when the first terminal block 220 and the second terminal block 330 are in elastic contact, making the contact between the first protrusion 3311 and the first sub-plate 221 more reliable, increasing the effective contact area between the third sub-plate 331 and the first sub-plate 221, ensuring the contact reliability between the first terminal block 220 and the second terminal block 330, and thus ensuring the reliability of the switch assembly 100.

[0077] Based on the switch assembly 100 provided in the above example, a guide structure is provided at the end of the third sub-plate 331 along the direction in which the second terminal block 330 extends into the first inlet port 211. The inclination direction of the guide structure is adapted to the direction in which the second terminal block 330 extends into the first inlet port 211.

[0078] The included angle formed by the guide structure and the second terminal block 330 is greater than 10 degrees and less than or equal to 30 degrees.

[0079] In this application example, by setting a guide structure in the direction of the first protrusion 3311 near the first inlet 211, and the inclination direction of the guide structure is adapted to the direction of the second terminal block 330 being inserted into the first inlet 211, based on this, during the assembly process of the second terminal block 330 extending into the first inlet 211 and the first terminal block 220, the smallest end of the second terminal block 330 can be inserted into the first inlet 211 first, which can improve the assembly efficiency of the second terminal block 330 and the first terminal block 220.

[0080] Based on the switch component 100 provided in the above example, please refer to Figures 1-5 The first partition plate 221 has a plurality of first grooves spaced apart on the side facing the third partition plate 331. The first partition plate 221 between two adjacent first grooves is a first contact surface, and at least a portion of the first contact surface elastically abuts against the third partition plate 331. And / or, the third partition plate 331 has a plurality of second grooves spaced apart on the side facing the first partition plate 221. The third partition plate 331 between two adjacent second grooves is a second contact surface, and at least a portion of the second contact surface elastically abuts against the first partition plate 221.

[0081] In this application example, multiple first grooves may be provided only on the side of the first sub-plate 221 facing the third sub-plate 331, or multiple second grooves may be provided only on the side of the third sub-plate 331 facing the first sub-plate 221. Alternatively, while providing first grooves on the side of the first sub-plate 221 facing the third sub-plate 331, second grooves may also be provided on the side of the third sub-plate 331 facing the first sub-plate 221. This application example does not impose specific limitations on this.

[0082] When a first groove is provided on the side of the first partition plate 221 facing the third partition plate 331, and a second groove is provided on the side of the third partition plate 331 facing the first partition plate 221, the projection of the first contact surface and the projection of the corresponding second contact surface can completely overlap along the direction from the first partition plate 221 to the third partition plate 331, and the projection of the first contact surface and the projection of the corresponding second contact surface can also partially overlap.

[0083] When multiple first grooves are provided on the side of the first partition plate 221 facing the third partition plate 331, the distance between two adjacent first grooves can be equal or unequal. That is, the areas of different first contact surfaces can be equal or unequal. As long as at least part of the first contact surface elastically abuts against the third partition plate 331, the elastic abutment between the first partition plate 221 and the third partition plate 331 can be achieved.

[0084] When multiple second grooves are provided on the side of the third plate 331 facing the first plate 221, the distance between two adjacent second grooves can be equal or unequal. That is, the areas of different second contact surfaces can be equal or unequal. As long as at least part of the second contact surface elastically abuts against the first plate 221, the elastic abutment between the third plate 331 and the first plate 221 can be achieved.

[0085] When the first protrusion 3311 is provided on the side of the third sub-plate 331 facing the first sub-plate 221, the second groove can be provided only on the side of the first protrusion 3311 facing the first sub-plate 221, or the second groove can be partially provided on the side of the first protrusion 3311 facing the first sub-plate 221.

[0086] In this application example, when multiple first grooves are provided at intervals on the side of the first sub-plate 221 facing the third sub-plate 331, the multiple first grooves divide the side of the first sub-plate 221 facing the third sub-plate 331 into multiple spaced first contact surfaces. The first contact surfaces elastically abut against the third sub-plate 331, which can reduce the possibility of different first contact surfaces affecting each other, thereby increasing the effective contact area between the first sub-plate 221 and the third sub-plate 331 and ensuring the contact reliability between the first sub-plate 221 and the third sub-plate 331.

[0087] When multiple second grooves are provided at intervals on the side of the third sub-plate 331 facing the first sub-plate 221, the multiple second grooves divide the side of the third sub-plate 331 facing the first sub-plate 221 into multiple spaced second contact surfaces. The second contact surfaces elastically abut against the first sub-plate 221, which can reduce the possibility of different second contact surfaces affecting each other, thereby increasing the effective contact area between the third sub-plate 331 and the first sub-plate 221 and ensuring the contact reliability between the third sub-plate 331 and the first sub-plate 221.

[0088] Based on the switch assembly 100 provided in the above example, the first terminal block 220 further includes a fifth sub-block (not shown in the figure). The fifth sub-block is located at the end of the second sub-block 222 opposite to the first sub-block 221, and is located on the side of the second sub-block 222 facing the first inlet port 211. The second terminal block 330 further includes a sixth sub-block 333. The sixth sub-block 333 is located at the end of the fourth sub-block 332 opposite to the third sub-block 331, and is located along the direction in which the second terminal block 330 extends into the first inlet port 211. The sixth sub-block 333 and the third sub-block 331 are located on the same side of the fourth sub-block 332. The maximum distance between the sixth sub-block 333 and the third sub-block 331 is less than the minimum distance between the fifth sub-block and the first sub-block 221. The fifth sub-block and the sixth sub-block 333 are elastically abutted.

[0089] In the switch assembly 100, only one of the fifth sub-board and the aforementioned wiring frame is provided. The fifth sub-board can be fixedly connected to the second sub-board 222 by welding, riveting, or other methods, or the fifth sub-board can be integrally formed with the second sub-board 222. The first wiring board 220 formed by the cooperation of the fifth sub-board, the second sub-board 222, and the first sub-board 221 can be integrally formed by stamping or other methods.

[0090] The fifth branch board is located at the end of the second branch board 222 opposite to the first branch board 221, and is also located on the side of the second branch board 222 facing the first inlet port 211. In other words, the first terminal block 220 formed by the fifth branch board, the second branch board 222, and the first branch board 221 has a "U"-shaped structure, with the opening of the "U"-shaped structure facing the first inlet port 211. The fifth branch board and the first branch board 221 can be substantially parallel; that is, the included angle formed by the fifth branch board and the first branch board 221 is less than or equal to 5 degrees.

[0091] The second connector 330 also includes a sixth sub-plate 333, which is located at the end of the fourth sub-plate 332 away from the third sub-plate 331 and extends into the first inlet port 211 along the direction of the second connector 330. The sixth sub-plate 333 and the third sub-plate 331 are located on the same side of the fourth sub-plate 332. That is, after the second connector 330 extends into the first housing 210 from the first inlet port 211, the sixth sub-plate 333 and the third sub-plate 331 are both located in the direction of the fourth sub-plate 332 towards the first inlet port 211. The second connector 330 formed by the cooperation of the sixth sub-plate 333, the fourth sub-plate 332 and the third sub-plate 331 has a "U" shaped structure. After the second connector 330 extends into the first housing 210 from the first inlet port 211, the opening of the "U" shaped structure is set towards the first inlet port 211. The sixth plate 333 and the third plate 331 can be basically parallel, that is, the included angle formed by the sixth plate 333 and the third plate 331 is less than or equal to 5 degrees.

[0092] In this example, the fifth sub-board is part of the first terminal block 220 and is located at the end of the second sub-board 222 away from the first sub-board 221. The sixth sub-board 333 is part of the second terminal block 330 and is located at the end of the first sub-board 221 away from the third sub-board 331. Therefore, the contact position between the sixth sub-board 333 and the fifth sub-board is independent of the contact position between the first sub-board 221 and the third sub-board 331, and the contact position between the sixth sub-board 333 and the fifth sub-board is independent of the contact position between the second sub-board 222 and the fourth sub-board 332. This can reduce the possibility of mutual influence between the contact position between the sixth sub-board 333 and the fifth sub-board and the contact positions between the first sub-board 221 and the third sub-board 331, as well as the contact position between the second sub-board 222 and the fourth sub-board 332, thus ensuring the contact reliability between the first terminal block 220 and the second terminal block 330.

[0093] Furthermore, since the maximum distance between the sixth sub-board 333 and the third sub-board 331 is less than the maximum distance between the fifth sub-board and the first sub-board 221, the contact reliability between the sixth sub-board 333 and the fifth sub-board, as well as the contact reliability between the third sub-board 331 and the first sub-board 221, can be further guaranteed, and the contact reliability between the first terminal block 220 and the second terminal block 330 can be further guaranteed.

[0094] Based on the switch component 100 provided in the above example, Figure 7 This application provides a schematic diagram illustrating the interaction between a second terminal block and an accessory body. Figure 8 Please refer to the structural schematic diagram of a base provided as an example in this application. Figure 1 , Figure 3 , Figure 7 as well as Figure 8 The second housing 340 includes a first sub-housing 312 and a second sub-housing 322, and the wiring accessory 300 includes an accessory body 310 and a base 320. The accessory body 310 includes a first connector 311 and a first sub-housing 312. The side wall of the first sub-housing 312 is provided with a mounting hole. The first connector 311 is fixedly installed inside the first sub-housing 312, and the setting position of the first connector 311 corresponds to the setting position of the mounting hole. The first sub-housing 312 is detachably connected to the first housing 210. The first connector 311 is fixedly connected to the second wiring board 330, and at least part of the second wiring board 330 is located outside the first sub-housing 312. The base 320 includes a second connector 321 and a second sub-housing 322 that are fixedly connected. The second sub-housing 322 is detachably connected to the first sub-housing 312. A portion of the second connector 321 extends to the outside of the second sub-housing 322. The portion of the second connector 321 extending to the second sub-housing 322 extends into the first sub-housing 312 through a mounting hole and is detachably connected to the first connector 311. The side wall of the second sub-housing 322 is provided with a second cable inlet 3221.

[0095] Wiring accessory 300 includes accessory body 310 and base 320. One base 320 can mate with only one switch body 200, or one base 320 can mate with multiple switch bodies 200 simultaneously. One base 320 can be connected to only one accessory body 310, or one base 320 can be connected to multiple accessory bodies 310. This application example does not impose specific limitations on this.

[0096] The accessory body 310 may include a first body and a second body. The first sub-shell 312 corresponding to the first body is the first accessory shell, and the first sub-shell 312 corresponding to the second body is the second accessory shell. On the side of the accessory body 310 away from the operating mechanism 230, the first accessory shell and the second accessory shell can be in direct contact. Alternatively, the first accessory shell has a first connecting structure on the side facing the second accessory shell, and the second accessory shell has a second connecting structure on the side facing the first accessory shell. The first connecting structure and the second connecting structure cooperate to realize the cooperation between the first accessory shell and the second accessory shell, ensuring the reliability of the connection between the first accessory shell and the second accessory shell.

[0097] The first connecting structure can be a hook structure, in which case the second connecting structure is a snap-fit ​​structure, and the hook structure engages with the snap-fit ​​structure. Alternatively, the first connecting structure can be a snap-fit ​​structure, in which case the second connecting structure is a hook structure, and the hook structure engages with the snap-fit ​​structure. The first connecting structure can be a protruding structure, in which case the second connecting structure is a recessed structure, and the protruding structure extends into the recessed structure and engages with the recessed structure. Alternatively, the first connecting structure can be a protruding structure, in which case the second connecting structure is a recessed structure, and the protruding structure extends into the recessed structure and engages with the recessed structure.

[0098] There may be only one first connecting structure, or there may be multiple first connecting structures spaced apart. The number of second connecting structures is equal to the number of first connecting structures, and there is a one-to-one correspondence between the second connecting structures and the first connecting structures. When there are multiple first connecting structures spaced apart, the multiple first connecting structures may be the same or different. This application does not impose specific restrictions on this.

[0099] The first accessory body and the second accessory body have a symmetrical structure, which can reduce the manufacturing cost of the first accessory body and the second accessory body and simplify the assembly process of the switch assembly 100.

[0100] The first housing 210 and the first sub-housing 312 are detachably connected. The protruding structure or groove structure mentioned above, which cooperates with the first housing 210 to realize the detachable connection between the first housing 210 and the second housing 340, can be specifically provided in the first sub-housing 312.

[0101] The accessory body 310 also includes a first connector 311, which can be fixedly installed to the first sub-housing 312 by means of snap-fit, threaded connection or other methods. The first connector 311 can be fixedly connected to the second terminal block 330 by means of welding or other methods, or the first connector 311 can be integrally formed with the second terminal block 330.

[0102] The base 320 includes a second sub-shell 322 and a second connector 321. The second sub-shell 322 is detachably connected to the first sub-shell 312 by means of snap-fit, groove and protrusion engagement, etc. The second connector 321 is detachably connected to the first connector 311 by means of insertion, snap-fit, elastic abutment, etc. When the first sub-shell 312 and the second sub-shell 322 are snap-fitted together, and the first connector 311 and the second connector 321 are snap-fitted together, the snap-fit ​​direction of the first sub-shell 312 and the second sub-shell 322 is the same as the snap-fit ​​direction of the first connector 311 and the second connector 321, so that the operator can assemble and disassemble the accessory body 310 and the base 320.

[0103] In this example, since the first connector 311 is part of the accessory body 310, and both the accessory body 310 and the second terminal block 330 are part of the wiring accessory 300, and the second terminal block 330 is connected to the switch body 200, the electrical connection between the accessory body 310 and the switch body 200 can be achieved through the fixed connection between the first connector 311 and the second terminal block 330. Based on this, the external wire is connected to the accessory body 310 through the base 320, and can be connected to the switch body 200 through the accessory body 310, thereby achieving the connection between the external wire and the switch body 200.

[0104] Furthermore, since the first sub-shell 312 and the first connector 311 are both part of the accessory body 310, and the second sub-shell 322 and the second connector 321 are both part of the base 320, the accessory body 310 and the base 320 can be detachably connected through the detachable connection of the first sub-shell 312 and the second sub-shell 322, and the detachable connection of the first connector 311 and the second connector 321. This allows the switch body 200 and the accessory body 310 to be detachably connected to the base 320 as a whole during the maintenance or repair of the switch assembly 100, avoiding the need to remove the external wires corresponding to a single switch body 200, thereby reducing the labor costs incurred during the use of the switch assembly 100 due to maintenance or repair.

[0105] Based on the switch component 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 protrusion, such as a protrusion point, protrusion strip, or protrusion column provided on the first sidewall 3111. The second protrusion can also be a protrusion structure formed by bending the second sidewall 3112.

[0112] The third protrusion can be fixedly disposed on the second sidewall 3112, and the third protrusion can also be movable relative to the second sidewall 3112. Specifically, the second sidewall 3112 may include a sidewall body and a second mounting part. The second mounting part has a second protrusion on the side facing the first sidewall 3111. One end of the second mounting part is fixedly connected to the sidewall body, and the other end of the second mounting part is a free end, so as to realize that the second protrusion can be movable relative to the second sidewall 3112.

[0113] When the second sidewall 3112 includes a sidewall body and a second mounting part, the second sub-housing 322 is provided with a snap-fit ​​groove at the position corresponding to the sidewall body. The snap-fit ​​groove is used to snap the sidewall body near the free end of the second mounting part to ensure the reliability of the connection between the second connector 321 and the second sub-housing 322.

[0114] Based on the above, a second protrusion may be provided only on the side of the first sidewall 3111 facing the second sidewall 3112, or a third protrusion may be provided only on the side of the second sidewall 3112 facing the first sidewall 3111, or a third protrusion may be provided on the side of the second sidewall 3112 facing the first sidewall 3111 while a second protrusion is provided on the first sidewall 3111. This application example does not impose specific limitations on this.

[0115] In this application example, the first sidewall 3111 is part of the first connector 311, and the third sidewall is part of the second connector 321. A second protrusion is provided on the side of the first sidewall 3111 facing the second sidewall 3112, and the second protrusion can abut against the third sidewall. During the connection process between the first connector 311 and the second connector 321, the second protrusion can reduce the gap between the first sidewall 3111 and the third sidewall, making the abutment between the third sidewall and the first sidewall 3111 more reliable, thereby making the abutment between the first connector 311 and the second connector 321 more reliable.

[0116] The second sidewall 3112 is part of the first connector 311, and the fourth sidewall is part of the second connector 321. A third protrusion is provided on the side of the second sidewall 3112 facing the first sidewall 3111, and the third protrusion can abut against the fourth sidewall. During the connection process between the first connector 311 and the second connector 321, the third protrusion can reduce the gap between the second sidewall 3112 and the fourth sidewall, making the abutment between the fourth sidewall and the second sidewall 3112 more reliable, thereby making the abutment between the first connector 311 and the second connector 321 more reliable.

[0117] Based on the switch component 100 provided in the above example, please refer to Figure 6 The first connector 311 includes an insertion port 3113, which is connected to the mounting hole. When a second protrusion is provided on the side of the first sidewall 3111 facing the second sidewall 3112, a first guide surface and a second guide surface are provided on the side of the first sidewall 3111 facing the second sidewall 3112. The first guide surface is provided on the side of the second protrusion near the insertion port 3113. The inclination direction of the first guide surface is adapted to the direction in which the second connector 321 is inserted into the first connector 311, and the inclination direction of the second guide surface is adapted to the direction in which the second connector 321 is disengaged from the first connector 311.

[0118] The first sidewall 3111 and the second sidewall 3112 cooperate to form an insertion port 3113. The insertion port 3113 communicates with the mounting hole, so that the second connector 321 can pass through the mounting hole and the insertion port 3113 in sequence to connect with the first connector 311.

[0119] Whether the second protrusion is provided only on the first sidewall 3111, or a second protrusion is provided on the first sidewall 3111 while a third protrusion is provided on the second sidewall 3112, both fall under the category of providing a second protrusion on the side of the first sidewall 3111 facing the second sidewall 3112. In this case, at least one of a first guide surface and a second guide surface can be provided on the first sidewall 3111. The included angle formed by the first guide surface and the first sidewall 3111 is greater than 10 degrees and less than or equal to 30 degrees. Similarly, the included angle formed by the second guide surface and the first sidewall 3111 is greater than 10 degrees and less than or equal to 30 degrees, so that the second connector 321 can slide relative to the first connector 311, thereby improving the assembly efficiency of the second connector 321 and the first connector 311.

[0120] In this application example, by setting a first guide surface in the direction of the second protrusion near the insertion port 3113, and the inclination direction of the first guide surface is adapted to the direction of the second connector 321 being inserted into the first connector 311, based on this, during the assembly process of the second connector 321 and the first connector 311, the second connector 321 can first extend into the position with the largest size among the first side wall 3111 and the second side wall 3112, which can improve the assembly efficiency of the second connector 321 and the first connector 311.

[0121] By providing a second guide surface in the direction of the second protrusion away from the insertion port 3113, and the inclination direction of the second guide surface being adapted to the direction in which the second connector 321 disengages from the first connector 311, during the assembly process of the second connector 321 and the first connector 311, the second connector 321 can gradually move from the position with the largest size between the first sidewall 3111 and the second sidewall 3112 to the position with the smallest size between the first sidewall 3111 and the second sidewall 3112, and finally disengage from the first connector 311. This can reduce the frictional force during the process of the second connector 321 disengaging from the first connector 311, reduce the possibility of wear caused by the second connector 321 during the process of disengaging from the first connector 311, and improve the efficiency of the second connector 321 disengaging from the first connector 311.

[0122] Based on the above, when a third protrusion is provided on the side of the second sidewall 3112 facing the first sidewall 3111, a third guide surface and a fourth guide surface are provided on the side of the second sidewall 3112 facing the first sidewall 3111. The third guide surface is provided on the side of the third protrusion near the insertion port 3113. The inclination direction of the third guide surface is adapted to the direction in which the second connector 321 is inserted into the first connector 311, and the inclination direction of the fourth guide surface is adapted to the direction in which the second connector 321 is disengaged from the first connector 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. The examples in this application will not be described in detail here.

[0124] Based on the switch component 100 provided in the above example, please refer to Figure 6 The accessory body 310 also includes a bent section 313. One end of the bent section 313 is fixedly connected to the first side wall 3111, and the other end of the bent section 313 is connected to the second terminal block 330. The thickness of the bent section 313 is less than the thickness of the first side wall 3111, and the thickness of the bent section 313 is less than the thickness of the second terminal block 330.

[0125] The bent section 313 can be fixedly connected to the first connector 311 and the second connector plate by welding or other means. The bent section 313 can also be integrally formed with the first connector 311 and the second connector plate 330. This application example does not impose specific limitations on this.

[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 dimension of the bent segment 313 in the direction of the circle corresponding to the arc-shaped structure.

[0127] The thickness of the first sidewall 3111 refers to the dimension of the first sidewall 3111 in the direction from the first sidewall 3111 toward the second sidewall 3112.

[0128] The thickness of the second terminal block 330 refers to the size of the second terminal block 330 in the direction from the first terminal block 220 toward the second terminal block 330, when the first terminal block 220 and the second terminal block 330 are in elastic contact.

[0129] The thickness of the first sidewall 3111 and the thickness of the second terminal block 330 can be equal or unequal. For example, if the thickness of the first sidewall 3111 and the thickness of the second terminal block 330 are equal, the thickness of the bent section 313 can be less than or equal to 95% of the thickness of the first sidewall 3111, and greater than or equal to 50% of the thickness of the first sidewall 3111. This application example does not specifically limit the relationship between the thickness of the bent section 313, the thickness of the first sidewall 3111, and the thickness of the second terminal block 330, as long as the reliability of the bent section 313 is ensured.

[0130] In this application example, since the first sidewall 3111 is part of the first connector 311, the connection between the first connector 311 and the second connector 330 can be achieved by connecting one end of the bent section 313 to the first sidewall 3111 and the other end of the bent section 313 to the second terminal block 330. By setting the thickness of the bent section 313 to be less than the thickness of the first sidewall 3111 and less than the thickness of the second terminal block 330, the deformation of the bent section 313 can be increased, thereby increasing the range of motion of the first sidewall 3111 relative to the second terminal block 330, further ensuring the reliability of the connection between the first connector 311 and the second connector 321.

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