Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of relays, and in particular to a relay, a battery system and an electrical device. BACKGROUND

[0002] A relay is usually applied in an automatic control circuit, and is a kind of "automatic switch" for controlling a larger current with a smaller current. The relay plays a role of automatic adjustment, safety protection and conversion of a circuit. The relay can include an auxiliary assembly, a contact assembly and a bracket, and the contact assembly and the auxiliary assembly are connected through the bracket.

[0003] However, the connection stability between the auxiliary assembly and the bracket of the relay in the related technology is poor, which affects the structural stability of the relay. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a relay, a battery system and an electrical device, which are used to solve the technical problem of poor connection stability between the auxiliary assembly and the bracket of the relay in the related technology, which affects the structural stability of the relay.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0006] The first aspect of the present application provides a relay, which comprises:

[0007] a bracket;

[0008] an auxiliary assembly connected with the bracket in a sliding manner along a first direction, and the auxiliary assembly has a mounting surface facing the bracket;

[0009] a limiting assembly comprising a first elastic sheet and a first limiting block;

[0010] The first elastic sheet is arranged on the bracket, and the first elastic sheet has a first abutting end which is warped towards the mounting surface relative to the bracket;

[0011] The first limiting block is arranged on the mounting surface, and the first abutting end abuts against the first limiting block to limit the movement of the auxiliary assembly in the opposite direction of the first direction.

[0012] The present application provides a relay, which arranges the first elastic sheet in the limiting assembly on the bracket, and warps the first abutting end on the first elastic sheet towards the mounting surface of the contact assembly, and arranges the first limiting block on the side of the auxiliary assembly facing the bracket, so that the first abutting end abuts against the first limiting block, thereby being able to limit the movement of the auxiliary assembly in the opposite direction of the first direction, and the abutting manner of the first elastic sheet and the first limiting block will not cause the problem of the protruding point coming out of the clamping hole in the prior art.

[0013] Therefore, the abutting limiting mode of the first elastic sheet and the first limiting block can avoid mutual disengagement of the auxiliary assembly and the support after the sliding connection, thereby improving the connection stability between the auxiliary assembly and the support, and further improving the structural stability of the relay.

[0014] The first elastic sheet and the first limiting block have relatively low requirements for manufacturing tolerance, and thus have relatively low requirements for manufacturing precision. Compared with the processing difficulty of the clamping hole and the protruding point in the prior art, the processing difficulty of the first elastic sheet and the first limiting block is reduced, thereby reducing the processing difficulty of the limiting assembly, and further reducing the manufacturing difficulty of the relay.

[0015] On the basis of the above technical solutions, the application can also be improved as follows.

[0016] In a possible implementation manner, the auxiliary assembly has a sliding-in initial end and a sliding-in terminal end opposite in the first direction;

[0017] The first elastic sheet gradually inclines toward the mounting surface in the first direction, and the first abutting end is arranged close to the sliding-in initial end relative to the sliding-in terminal end.

[0018] In a possible implementation manner, the first limiting block comprises an abutting portion and an inclined portion;

[0019] The abutting portion is arranged on the mounting surface and is used for abutting against the first abutting end;

[0020] One end of the inclined portion is arranged on the mounting surface, and the other end of the inclined portion is connected to one end of the abutting portion toward the support. The inclined portion is close to the sliding-in initial end relative to the abutting portion.

[0021] In a possible implementation manner, the first elastic sheet abuts against the mounting surface of the auxiliary assembly, and the first elastic sheet is used for applying an acting force in the direction from the support to the auxiliary assembly to the auxiliary assembly.

[0022] In a possible implementation manner, the relay further comprises a sliding assembly;

[0023] The sliding assembly is used for slidingly connecting the auxiliary assembly and the support, and the sliding assembly is used for limiting movement of the auxiliary assembly in a third direction, and the third direction is perpendicular to the first direction.

[0024] In a possible implementation manner, the sliding assembly comprises;

[0025] A guide rail is arranged on the auxiliary assembly, and the guide rail has a sliding groove extending in the first direction.

[0026] A sliding member is arranged on the bracket, and the sliding member is arranged in the sliding groove. The guide rail and the auxiliary assembly move relative to the sliding member along the first direction.

[0031] The second abutting end is used to jointly hold the groove wall of the sliding groove with the bracket.

[0032] In a possible implementation, the guide rail is two, and each of the guide rails has one sliding groove. The two guide rails are arranged in a spaced manner along a second direction, and the first limiting block is arranged between the two guide rails. The second direction is perpendicular to the first direction.

[0033] The second elastic sheet is also two, and the second abutting end of each of the second elastic sheets is arranged in the sliding groove in a sliding manner.

[0034] In a possible implementation, the sliding assembly includes two thickened plates. Each of the guide rails has one thickened plate arranged on the outer surface of the bracket. The thickened plate is used to increase the distance between the second abutting end of the second elastic sheet and the bracket.

[0035] In a possible implementation, along the first direction, the thickened plate is shorter than the first end towards the end of the first end of the sliding groove.

[0036] In a possible implementation, the surfaces of the two thickened plates towards the bracket are in the same plane.

[0037] In a possible implementation, the relay further includes a contact assembly. The contact assembly is located on the side of the bracket away from the mounting surface, and the sliding assembly is in sliding connection with the auxiliary assembly on the side of the bracket away from the contact assembly.

[0065] As described in the background, the connection stability between the auxiliary assembly and the bracket of the relay in the prior art is poor, which affects the structural stability of the relay. The reason for this problem is that the connection between the auxiliary assembly and the bracket in the prior art is a sliding connection in the horizontal direction and can limit the displacement of the auxiliary assembly and the bracket in the height direction through the track and the sliding block. The relay in the prior art also includes a buckle, and the auxiliary assembly and the bracket are further connected using the buckle to limit the displacement amount of the auxiliary assembly and the bracket in the horizontal direction, wherein the buckle includes a protrusion and a clamping hole, and the clamping hole is opened on the bracket, and the protrusion is arranged on the side of the auxiliary assembly facing the bracket.

[0066] However, due to the connection mode of the protrusion and the clamping hole, the clamping hole and the protrusion need to have high matching precision, so that the protrusion does not shake in the clamping hole. In addition, the abutment between the protrusion and the clamping hole mainly relies on friction to maintain stability, and when the external force or vibration exceeds the range that the friction can withstand, the protrusion is also easy to come out of the clamping hole, resulting in the failure of the buckle to limit the auxiliary assembly and the bracket in the horizontal direction.

[0067] In addition, the protrusion and the auxiliary assembly are usually plastic parts, and after long-term use, the plastic parts are easy to deform, causing the connection between the protrusion and the clamping hole to fail.

[0068] Therefore, the connection stability between the auxiliary assembly and the bracket of the relay in the prior art is poor, which affects the structural stability of the relay.

[0069] In addition, in the prior art, the auxiliary assembly is arranged above the bracket, the contact assembly is arranged below the bracket, the auxiliary assembly is provided with a rail, the bracket is provided with a corresponding sliding block, and the rail is connected with the sliding block. When the rail is connected with the sliding block, part of the rail is located below the bracket, thereby occupying the space below the bracket. The part of the rail located below the bracket occupies the mounting space of the contact assembly or affects the arrangement of the structure on the contact assembly. If the contact assembly includes a magnetic yoke arranged below the bracket, the size of the magnetic yoke is limited by the rail because part of the rail is located below the bracket. The smaller size of the magnetic yoke reduces the constraint effect of the magnetic yoke on the contact structure in the contact assembly.

[0070] To solve the above technical problems, the embodiments of the present application provide a relay, a battery system and a power consumption device. The relay sets a first elastic sheet in the limiting assembly to the bracket, and the first elastic sheet is warped toward the mounting surface of the contact assembly at a first abutting end. A first limiting block is arranged on the side of the auxiliary assembly facing the bracket, so that the first abutting end and the first limiting block abut, thereby limiting the movement of the auxiliary assembly in the opposite direction of the first direction. The abutting mode of the first elastic sheet and the first limiting block does not have the problem that the protrusion is pulled out of the clamping hole in the prior art.

[0071] Therefore, the abutting limiting mode of the first elastic sheet and the first limiting block can avoid the mutual disengagement of the auxiliary assembly and the bracket after the sliding connection, thereby improving the connection stability between the auxiliary assembly and the bracket, and further improving the structural stability of the relay.

[0072] The first elastic sheet and the first limiting block have relatively low requirements for manufacturing tolerances, and thus have relatively low requirements for manufacturing precision. Compared with the machining difficulty of the clamping hole and the protrusion in the prior art, the machining difficulty of the first elastic sheet and the first limiting block is reduced, thereby reducing the machining difficulty of the limiting assembly and further reducing the manufacturing difficulty of the relay.

[0073] In order to make the above-mentioned purposes, characteristics and advantages of the embodiments of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0074] Reference Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides a relay, which can include a support 100, an auxiliary assembly 200 and a limiting assembly 300. The auxiliary assembly 200 is used for assisting in judging the connection state between the relay and an external circuit. The relay can further include a contact assembly 500, which can be used for ensuring the electrical connection state of the external circuit. The contact assembly 500 and the auxiliary assembly 200 are connected with the support 100, and the contact assembly 500 and the auxiliary assembly 200 can be located on two opposite surfaces in the thickness direction of the support 100.

[0075] With reference to Figure 1 , Figure 2 and Figure 3 , the support 100 has an upper surface and a lower surface, the support 100 can be a metal frame, and the support 100 can be used for carrying the auxiliary assembly 200.

[0076] The auxiliary assembly 200 can be arranged on the upper surface of the support 100, and the auxiliary assembly 200 is connected with the support 100 in sliding along a first direction (such as the +X direction in the figure). Figure 3 In some embodiments, the auxiliary assembly 200 is connected with the support 100 in sliding through a sliding assembly 400.

[0077] The auxiliary assembly 200 can also be connected with the support 100 in limiting through the limiting assembly 300, when the sliding connection between the auxiliary assembly 200 and the support 100 is completed, the limiting assembly 300 can limit the auxiliary assembly 200 from moving in the reverse direction of the first direction (such as the -X direction in the figure) relative to the support 100, so as to avoid the auxiliary assembly 200 from moving in the reverse direction of the first direction (such as the -X direction in the figure) and separating from the support 100. Figure 3 Figure 3 With reference to and

[0078] , in some embodiments, the limiting assembly 300 can include a first elastic sheet 310 and a first limiting block 320. One of the auxiliary assembly 200 and the support 100 is provided with the first elastic sheet 310, and the other of the auxiliary assembly 200 and the support 100 is provided with the first limiting block 320. The first elastic sheet 310 has a first abutting end 311, and the first abutting end 311 can be warped towards the first limiting block 320, so as to abut against the first limiting block 320. Figure 2 Figure 3 With reference to , in some examples, the first elastic sheet 310 can be arranged on the support 100, and the first elastic sheet 310 has the first abutting end 311 warped towards the mounting surface 210 relative to the support 100.

[0079] Figure 3

[0080] ​​The first limiting block 320 can be arranged on the mounting surface 210, and the first abutting end 311 abuts against the first limiting block 320 to limit the auxiliary assembly 200 from moving away from the bracket 100 in the first direction. When the first abutting end 311 of the first elastic sheet 310 abuts against the first limiting block 320, the first abutting end 311 of the first elastic sheet 310 can apply a force in the first direction to the first limiting block 320 to prevent the first limiting block 320 from moving in the opposite direction of the first direction, thereby preventing the auxiliary assembly 200 from moving in the opposite direction of the first direction.

[0081] The relay provided by the embodiment of the present application can be arranged by arranging the first elastic sheet 310 in the limiting assembly 300 on the bracket 100, and bending the first abutting end 311 on the first elastic sheet 310 towards the mounting surface 210 of the contact assembly 500, and arranging the first limiting block 320 on the side of the auxiliary assembly 200 facing the bracket 100, so that the first abutting end 311 abuts against the first limiting block 320, thereby limiting the auxiliary assembly 200 from moving in the opposite direction of the first direction, and the abutting mode of the first elastic sheet 310 and the first limiting block 320 will not cause the protrusion to come out of the clamping hole as in the prior art.

[0082] Therefore, the abutting limiting mode of the first elastic sheet 310 and the first limiting block 320 can prevent the auxiliary assembly 200 and the bracket 100 from moving away from each other after the sliding connection, thereby improving the connection stability between the auxiliary assembly 200 and the bracket 100, and further improving the structural stability of the relay.

[0083] The first elastic sheet 310 and the first limiting block 320 have relatively low requirements for manufacturing tolerances, and thus have relatively low requirements for manufacturing precision. The first elastic sheet 310 and the first limiting block 320 have lower processing difficulty than the clamping hole and the protrusion in the prior art, thereby reducing the processing difficulty of the limiting assembly 300, and further reducing the manufacturing difficulty of the relay.

[0084] Reference Figure 1 and Figure 2 In some embodiments, the relay can further include the contact assembly 500, which is located on the side of the bracket 100 away from the mounting surface 210, and the sliding assembly 400 is in sliding connection with the auxiliary assembly 200 on some sides of the bracket 100 away from the contact assembly 500.

[0085] Reference Figure 3 , Figure 4 and Figure 5The auxiliary component 200 may include an insulating plate 250 and an auxiliary contact 240. The insulating plate 250 has a mounting surface 210, and a first limiting block 320 can be disposed on the mounting surface 210 of the insulating plate 250. The insulating plate 250 and the first limiting block 320 can be an integrally molded structure to reduce the number of components in the relay and improve assembly efficiency. The auxiliary contact 240 can be disposed on the side of the insulating plate 250 facing away from the bracket 100, and the auxiliary contact 240 can be used for electrical connection with an external auxiliary detection circuit. The insulating plate 250 can be a plastic or rubber component.

[0086] refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the auxiliary component 200 has a sliding head end 220 and a sliding tail end 230 that are opposite to each other along a first direction. The direction from the sliding head end 220 to the sliding tail end 230 is the opposite direction to the first direction (e.g., ...). Figure 3 The direction from the sliding end 230 to the sliding head 220 (in the middle-X direction) is the first direction (e.g., Figure 3 (Center + X direction). During the connection process between the auxiliary component 200 and the bracket 100, the sliding head 220 of the auxiliary component 200 first makes sliding contact with the bracket 100. As the sliding process proceeds, the sliding tail 230 of the auxiliary component 200 finally makes sliding contact with the bracket 100, thus completing the sliding connection between the auxiliary component 200 and the bracket 100.

[0087] In some examples, the first shrapnel 310 is along a first direction (e.g., Figure 3 The first abutting end 311 is positioned close to the sliding head end 220 relative to the sliding end end 230, gradually tilting towards the mounting surface 210 in the middle + X direction.

[0088] Thus, in the direction from the sliding end 230 to the sliding head 220, the distance between the first spring piece 310 and the bracket 100 gradually increases, causing the first abutting end 311 of the first spring piece 310 to warp. When the auxiliary component 200 and the bracket 100 are in a connected state, the first abutting end 311 abuts against the first limiting block 320, thereby allowing the first abutting end 311 to apply pressure to the first limiting block 320 along a first direction (such as...). Figure 3 The force acting in the middle + X direction can limit the auxiliary component 200 in the opposite direction of the first direction (e.g., ... Figure 3 Move in the X direction to prevent the auxiliary component 200 and the bracket 100 from detaching from each other.

[0089] refer to Figure 5 In some embodiments, the first limiting block 320 may include an abutting portion 321 and an inclined portion 322.

[0090] The abutting part 321 is disposed on the mounting surface 210 and is used to abut against the first abutting end 311. One end of the inclined part 322 is disposed on the mounting surface 210, and the other end of the inclined part 322 is connected to the end of the abutting part 321 facing the bracket 100. The inclined part 322 slides into the first end 220 relative to the abutting part 321.

[0091] In this way, by setting one end of the inclined portion 322 on the mounting surface 210 and connecting the other end to the end of the abutment portion 321 facing the bracket 100, the inclined portion 322 can be closer to the sliding head end 220 relative to the abutment portion 321, so that the first spring piece 310 can contact the inclined portion 322 first, reducing the compression deformation of the first spring piece 310 by the first limiting block 320. This helps to reduce the sliding resistance of the auxiliary component 200 and the bracket 100 during the sliding connection process, and also reduces the amount of compression deformation of the first spring piece 310 by the first limiting block 320. This helps to increase the number of uses of the first spring piece 310, and ensures the elastic deformation ability of the first spring piece 310 during long-term repeated use, thereby improving the durability of the first spring piece 310.

[0092] refer to Figure 5 and Figure 6 In some embodiments, the relay may further include a sliding component 400 for slidingly connecting the auxiliary component 200 and the support 100, and the sliding component 400 for limiting the auxiliary component 200 along a third direction (e.g., Figure 6 The direction moves (in the Z direction), and the third direction is perpendicular to the first direction. Figure 6 Based on the orientation of the relay, the third direction can be the height direction of the relay. The sliding component 400 can restrict the movement of the auxiliary component 200 relative to the bracket 100 along the first direction, thereby improving the connection stability between the auxiliary component 200 and the bracket 100.

[0093] In some embodiments, the insulating plate 250 in the sliding assembly 400 and the auxiliary assembly 200 are integrally formed, thereby reducing the number of parts and improving assembly efficiency.

[0094] refer to Figure 5 and Figure 6 In some embodiments, the sliding assembly 400 may include a guide rail 410 and a slider 420. The guide rail 410 is disposed on the auxiliary assembly 200 and has a groove 411 extending along a first direction. The slider 420 is disposed on the bracket 100 and is disposed within the groove 411. The guide rail 410 and the auxiliary assembly 200 move relative to the slider 420 along the first direction to achieve a sliding connection between the auxiliary assembly 200 and the bracket 100. The groove wall of the groove 411 can limit the auxiliary assembly 200 in a third direction to prevent the auxiliary assembly 200 from disengaging from the bracket 100 in the third direction.

[0095] In some embodiments, in order to facilitate the relative sliding of the sliding groove 411 and the sliding piece 420, and to reduce the frictional resistance between the side walls of the sliding groove 411 and the sliding piece 420, the sliding piece 420 can be displaced in the third direction within the sliding groove 411, but this arrangement can cause the mounted auxiliary assembly 200 to slide relative to the support 100, reducing the connection stability between the auxiliary assembly 200 and the support 100.

[0096] With reference to Figure 3 , Figure 5 and Figure 6 , in some embodiments, in order to reduce the shaking problem of the above-mentioned auxiliary assembly 200 relative to the support 100, when the auxiliary assembly 200 and the support 100 are assembled, the first elastic sheet 310 can abut against the mounting surface 210 of the auxiliary assembly 200, and the first elastic sheet 310 is used to apply a force to the auxiliary assembly 200 in the direction from the support 100 to the auxiliary assembly 200. In addition, the first elastic sheet 310 abuts against and applies a force to the auxiliary assembly 200, which can cause the sliding groove 411 to abut against the inner side wall of the support 100 and the surface of the sliding piece 420 to abut against the support 100, so as to apply a force to the sliding piece 420 by the inner side wall of the sliding groove 411 in the direction from the auxiliary assembly 200 to the support 100. Under the action of the two opposite forces, the displacement of the auxiliary assembly 200 in the third direction can be limited, the shaking of the auxiliary assembly 200 can be avoided, and the connection stability between the auxiliary assembly 200 and the support 100 can be improved.

[0097] With reference to Figure 5 , in some embodiments, the sliding groove 411 has a first end 4111 and a second end 4112 opposite to each other in the first direction, the first end 4111 of the sliding groove 411 has a sliding entrance for the sliding piece 420 to slide into, and the second end 4112 of the sliding groove 411 has a second limiting part 412.

[0098] In this way, by arranging the second limiting part 412 at the second end 4112 of the sliding groove 411, the sliding piece 420 can abut against the second limiting part 412 to limit the further movement of the sliding rail in the first direction (e.g. the +X direction in the middle of the figure). Figure 5 In combination with the limiting assembly 300, the movement of the auxiliary assembly 200 in the opposite direction of the first direction can be limited, and thus the connection stability between the auxiliary assembly 200 and the support 100 can be further improved.

[0099] With reference to Figure 5 and Figure 6 , in some embodiments, the sliding piece 420 is a second elastic sheet, the second elastic sheet has a second abutting end 421 curved towards the mounting surface 210 relative to the support 100, the second abutting end 421 is slidingly arranged in the sliding groove 411, and the second abutting end 421 is used to clamp the groove wall of the sliding groove 411 together with the support 100.

[0100] In this way, by setting the sliding piece 420 as a second elastic sheet, when the second elastic sheet slides into the sliding groove 411, the second elastic sheet can generate elastic deformation towards the auxiliary assembly 200 by the bracket 100, and the second elastic sheet generates an acting force from the auxiliary assembly 200 to the bracket 100 by the elastic deformation, so as to clamp the slot wall between the second elastic sheet and the bracket 100 by the second elastic sheet and the bracket 100 together, which can limit the displacement of the auxiliary assembly 200 in the third direction, reduce the shaking of the auxiliary assembly 200, and improve the connection stability between the auxiliary assembly 200 and the bracket 100.

[0101] Reference Figure 5 and Figure 6 In some embodiments, the guide rail 410 is two, each guide rail 410 has a sliding groove 411, and the two guide rails 410 are arranged in the second direction (such as the Y direction in the figure) at intervals, and the first limiting block 320 is arranged between the two guide rails 410; the second direction is perpendicular to the first direction, and the second elastic sheet also has two, and the second abutting end 421 of each second elastic sheet is slidingly arranged in the sliding groove 411. Figure 5

[0102] In this way, by arranging two sliding grooves 411 and two second elastic sheets in the second direction, the connection points between the auxiliary assembly 200 and the sliding assembly 400 are increased, so as to improve the stability of the auxiliary assembly 200 during sliding, and the connection stability of the auxiliary assembly 200 in the height direction is also improved.

[0103] The first elastic sheet 310 and the second elastic sheet can be metal pieces, by setting the first elastic sheet 310 and the second elastic sheet as metal pieces, the structural strength and durability of the first elastic sheet 310 and the second elastic sheet can be improved

[0104] Reference Figure 6 and Figure 7 In some embodiments, the second elastic sheet and the first elastic sheet 310 are of an integrated structure.

[0105] In this way, by setting the first elastic sheet 310 and the second elastic sheet as an integrated structure, the number of parts can be reduced, and the assembly efficiency of the relay can be improved.

[0106] In other embodiments, the first elastic sheet 310 and the second elastic sheet can be connected to the bracket 100 by riveting, so as to increase the connection stability of the first elastic sheet 310, the second elastic sheet and the bracket 100.

[0107] Reference Figure 5 and Figure 6 ​In some embodiments, the sliding assembly 400 can include two thickened plates 430, one thickened plate 430 is arranged on each sliding rail towards the outer surface of the bracket 100, and the thickened plate 430 is used to increase the distance between the second abutting end 421 of the second elastic sheet and the bracket 100.

[0108] In this way, by arranging one thickened plate 430 on each sliding rail towards the outer surface of the bracket 100, the thickness of the groove wall of the sliding groove 411 between the second elastic sheet and the bracket 100 can be increased, so that the deformation amount of the second elastic sheet can be increased, and the force applied by the second elastic sheet to the groove wall towards the bracket 100 can be increased, and the connection stability between the auxiliary assembly 200 and the bracket 100 in the third direction can be further improved.

[0109] Reference Figure 5 In some embodiments, the surfaces of the two thickened plates 430 towards the bracket 100 are in the same plane. In this way, by arranging the surfaces of the two thickened plates 430 towards the bracket 100 in the same plane, the auxiliary assembly 200 can adjust the flatness through the two thickened plates 430 on the sliding assembly 400, and the structural stability can be improved.

[0110] Reference Figure 5 In some embodiments, along the first direction, the end of the thickened plate 430 towards the first end 4111 of the sliding groove 411 is shorter than the first end 4111.

[0111] In this way, the thickness of the sliding rail near the first end 4111 can be thinner than the thickness with the thickened plate 430, so that the deformation of the second elastic sheet caused by the wall thickness at the position of the first end 4111 can be smaller, and the second elastic sheet can be easily slid into the sliding groove 411.

[0112] In some embodiments, the sliding assembly 400 can be located on the side of the bracket 100 towards the auxiliary assembly 200, and after the second elastic sheet is connected to the sliding rail, the sliding assembly 400 can also be located on the side of the bracket 100 towards the auxiliary assembly 200.

Since the bracket 100 and the auxiliary assembly 200 are connected through the sliding assembly 400 on the side of the bracket 100 facing the auxiliary assembly 200, the part of the sliding assembly 400 can be avoided to be located on the side where the contact assembly 500 is located, so that the arrangement and connection mode between the auxiliary assembly 200 and the bracket 100 can be avoided to occupy the space on the side of the bracket 100 away from the auxiliary assembly 200, and then the size of the magnetic yoke 520 can be avoided to be limited by the auxiliary assembly 200, and then the binding effect of the magnetic yoke 520 on the contact piece 510 can be avoided to be affected.

[0114] Reference Figure 1 and Figure 2 In some embodiments, the contact assembly 500 can further include the insulating piece 530, the elastic piece 540, the base 550 and the solenoid 560, and a driving shaft (not shown in the figure).

[0115] The bracket 100 and the insulating piece 530 are arranged on the side of the base 550 facing the auxiliary assembly 200, the insulating piece 530 can be connected with the end of the bracket 100 facing the base 550, and the elastic piece 540 can be arranged between the magnetic yoke 520 and the insulating piece 530.

[0116] In some examples, the insulating piece 530 and the bracket 100 can be connected through a clamping mode.

[0117] The driving shaft is arranged in the solenoid 560, and the solenoid 560 is arranged on the side of the base 550 away from the auxiliary assembly 200, one end of the driving shaft facing the auxiliary assembly 200 is connected with the base 550, and the solenoid 560 can drive the driving shaft to move upward along the third direction in the state of being electrified, and the driving shaft can drive the insulating piece 530, the bracket 100, the contact piece 510 and the auxiliary assembly 200 on the base 550 to move upward, so that the contact piece 510 can keep in contact with the external circuit.
