Description

Technical Field

[0001] This application relates to the field of electronic control device technology, and more specifically, to a relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] A high-voltage DC relay is a type of relay. Existing high-voltage DC relays include a pair of stationary contact leads, a moving assembly, a coil unit, and a magnetic circuit. The moving assembly includes a moving spring assembly, a push rod assembly, and an elastic assembly. The moving spring assembly is mounted on the push rod assembly via the elastic assembly. The magnetic circuit includes a stationary iron core and a moving iron core. The stationary iron core is fixedly disposed within the relay, and the moving iron core is connected to the push rod assembly. When the coil unit is energized, the stationary iron core generates a magnetic force that attracts the moving iron core, thereby driving the push rod assembly and the moving spring assembly to move together, thus closing the contacts.

[0004] However, during relay operation, the moving spring assembly tends to rotate relative to the push rod around its axis, causing friction between the moving spring assembly and the contact support of the push rod assembly, resulting in significant metallic noise. Furthermore, with the frictional wear between the moving spring assembly and the contact support, the deflection angle of the moving spring assembly increases, affecting the contact position between the moving spring assembly and the stationary contact lead, leading to unstable contact resistance. In addition, the friction between the moving spring assembly and the contact support easily generates metal particles. When these metal particles fall onto the contact surface, they can increase the contact resistance or even cause the relay to fail to conduct. Summary of the Invention

[0018] According to some embodiments of this application, the moving spring assembly further includes a second magnetic conductor, which is fixedly connected to the side of the moving spring facing away from the stationary contact lead-out end; The transition piece is fixedly connected to the second magnetic conductor.

[0019] According to some embodiments of this application, the anti-rotation structure further includes a transition member; One end of the first anti-rotation component and one end of the second anti-rotation component are integrally connected to both ends of the transition component along the third direction; The push rod assembly also includes a stop wall, the two ends of which are connected to the first side wall and the second side wall respectively along the third direction; The transition piece is fixedly connected to the stop wall.

[0020] According to some embodiments of this application, the relay further includes a first magnetic conductor, which is disposed on the side of the moving spring assembly facing the stationary contact lead-out end; The transition member is disposed between the stop wall and the first magnetic conductor, and is fixedly connected to the stop wall and the first magnetic conductor.

[0022] According to some embodiments of this application, the push rod assembly further includes a rod portion and a base connected to one axial end of the rod portion; The contact support also includes a bottom wall, the two ends of which are integrally connected to one end of the first side wall and one end of the second side wall respectively along the third direction; the contact support, the rod and the base are connected by injection molding, and the base covers the bottom wall and one end of the first side wall and the second side wall; The push rod assembly also includes a stop wall, which is connected to the other end of the first side wall and the second side wall, and the stop wall is located on the side of the moving spring assembly facing the stationary contact lead-out end.

[0023] According to some embodiments of this application, the push rod assembly further includes a rod portion and a base connected to one axial end of the rod portion; The contact support also includes a top wall, the two ends of which are integrally connected to one end of the first side wall and one end of the second side wall, respectively, along the third direction.

[0069] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0070] like Figure 1 As shown, the relay 1 in this embodiment includes a housing 10, a coil unit 20, an arc-extinguishing unit 30, and a sealing unit 40. The sealing unit 40 is disposed inside the housing 10, and the top of the stationary contact lead-out end of the sealing unit 40 is exposed to the outer surface of the housing 10 through the exposure hole 11a. Both the coil unit 20 and the arc-extinguishing unit 30 are disposed inside the housing 10.

[0071] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0072] As an example, the outer casing 10 includes a first casing 11 and a second casing 12, which are connected to form a chamber for accommodating the coil unit 20, the arc-extinguishing unit 30, and the sealing unit 40. In an embodiment of this application, an exposure hole 11a is provided in the first casing 11.

[0073] The arc extinguishing unit 30 is used to extinguish the electric arc generated between the stationary contact lead-out end of the sealing unit 40 and the moving spring.

[0074] As an example, the arc-extinguishing unit 30 includes two arc-extinguishing magnets 31. The arc-extinguishing magnets 31 can be permanent magnets, and each arc-extinguishing magnet 31 can be approximately cuboid in shape. The two arc-extinguishing magnets 31 are respectively disposed on both sides of the sealing unit 40 and are arranged opposite each other along the length direction of the moving spring.

[0075] By setting two opposing arc-extinguishing magnets 31, a magnetic field can be formed around the stationary contact lead-out end and the moving spring. Therefore, the electric arc generated between the stationary contact lead-out end and the moving spring is elongated in a direction away from each other by the action of the magnetic field, thus extinguishing the arc.

[0076] The arc-extinguishing unit 30 also includes two yoke clips 32, which are positioned corresponding to the two arc-extinguishing magnets 31. Furthermore, the two yoke clips 32 surround the sealing unit 40 and the two arc-extinguishing magnets 31. This design of the yoke clips 32 surrounding the arc-extinguishing magnets 31 prevents the magnetic field generated by the arc-extinguishing magnets 31 from spreading outwards and affecting the arc-extinguishing effect. The yoke clips 32 are made of soft magnetic material. Soft magnetic materials can include, but are not limited to, iron, cobalt, nickel, and their alloys.

[0077] like Figures 2 to 6 As shown, the sealing unit 40 includes a contact container 1000, a pair of stationary contact leads 2000, a moving component 3000, and a magnetic circuit portion 4000.

[0078] It should be noted that the contact container 1000 is a stationary component, a device used to house the contact assembly, which is mainly a housing and has a chamber. Furthermore, the contact container 1000 can be assembled from multiple components connected in a predetermined assembly manner.

[0079] The contact container 1000 has a contact chamber 1001 inside. The contact container 1000 may include an insulating cover 1100 and a yoke plate 1200. The insulating cover 1100 covers one side surface of the yoke plate 1200, and the insulating cover 1100 and the yoke plate 1200 together form the contact chamber 1001.

[0080] The insulating cover 1100 includes a ceramic cover 1110 and a frame plate 1120. The ceramic cover 1110 is connected to the yoke plate 1200 via the frame plate 1120. The frame plate 1120 can be a ring-shaped metal component, such as an iron-nickel alloy, and one end of the frame plate 1120 is connected to the opening edge of the ceramic cover 1110, for example, by laser welding, brazing, resistance welding, or adhesive bonding. The other end of the frame plate 1120 is connected to the yoke plate 1200, also by laser welding, brazing, resistance welding, or adhesive bonding. The frame plate 1120 positioned between the ceramic cover 1110 and the yoke plate 1200 facilitates their connection.

[0081] The contact container 1000 also has a pair of first through holes 1002, which communicate with the contact chamber 1001. The first through holes 1002 are used for the stationary contact lead-out end 2000 to pass through them. In the embodiments of this application, the first through holes 1002 are formed on the ceramic cover 1110.

[0082] A pair of stationary contact leads 2000 are connected to the ceramic cover 1110 of the contact container 1000, with at least a portion of each stationary contact lead 2000 located within the contact chamber 1001. One of the pair of stationary contact leads 2000 serves as a current inflow terminal, and the other serves as a current outflow terminal.

[0083] A pair of stationary contact leads 2000 are inserted one-to-one into a pair of first through holes 1002 and connected to the ceramic cover 1110, for example by welding.

[0084] The bottom of the stationary contact lead-out terminal 2000 serves as the stationary contact. The stationary contact can be integrally or separately located at the bottom of the stationary contact lead-out terminal 2000.

[0085] Please continue reading. Figures 3 to 6 The moving assembly 3000 includes a moving spring assembly 3100, a push rod assembly 3200, and an elastic assembly 3300. The moving spring assembly 3100 is disposed within the insulating cover 1100 and is mounted on the push rod assembly 3200 via the elastic assembly 3300. The two ends of the moving spring assembly 3100 along a first direction D1 are used to contact or separate from a pair of stationary contact leads 2000, respectively. The first direction D1 is the arrangement direction of the pair of stationary contact leads 2000.

[0086] It should be noted that if a pair of stationary contact leads 2000 and a moving spring assembly 3100 are considered as a set of combinations, then the relays in the embodiments of this application may include multiple sets of combinations.

[0087] The moving spring assembly 3100 may include a moving spring 3110, the two ends of which along the first direction D1 are used to contact or separate from a pair of stationary contact leads 2000, respectively.

[0088] It is understandable that the number of moving reeds 3110 can be one or more.

[0089] Each movable spring 3110 may include a movable spring body and movable contacts located at both ends of the movable spring body. The movable contacts may be separate parts connected to the movable spring body. Alternatively, the movable contacts may be integrally formed onto the movable spring body.

[0090] In this embodiment of the application, the movable spring assembly 3100 includes two movable spring pieces 3110 arranged side by side. One end of each movable spring piece 3110 is used to contact or separate from the stationary contact of one of the stationary contact leads 2000, and the other end of each movable spring piece 3110 is used to contact or separate from the stationary contact of the other stationary contact lead 2000. Further, one end of each movable spring piece 3110 forms two contact points with one of the stationary contact leads 2000, and the other end of each movable spring piece 3110 forms two contact points with the other stationary contact lead 2000.

[0091] In other embodiments, the number of movable reeds 3110 may be one, three, four, five, etc.

[0092] It is understood that the moving spring assembly 3100 includes multiple moving springs 3110. The two ends of each moving spring 3110 along the first direction D1 respectively contact or separate from a pair of stationary contact leads. Since the multiple moving springs 3110 do not restrict each other, a reliable parallel circuit is formed after the two ends of each moving spring 3110 along the first direction D1 contact a pair of stationary contact leads 2000. The number of contacts formed by the multiple moving springs 3110 and one stationary contact lead 2000 is greater than or equal to two, achieving a current shunting effect. Furthermore, according to the principle that the magnitude of the electric repulsion force is proportional to the square of the current, the magnitude of the electric repulsion force at each contact is significantly reduced, which is beneficial to improving the short-circuit withstand capability and enhancing the reliability of the relay.

[0093] Furthermore, the moving spring assembly 3100 may also include a second magnetic conductor 6200, which is fixedly connected to the side of the moving spring 3110 facing away from the stationary contact lead-out end 2000. The function of the second magnetic conductor 6200 will be explained below.

[0094] The moving spring assembly 3100 includes a corresponding number of moving spring pieces 3110 and second magnetic conductors 6200. Specifically, when there is one moving spring piece 3110, there is also one second magnetic conductor 6200; when there are multiple moving spring pieces 3110 (including two), there are also multiple second magnetic conductors 6200. Multiple second magnetic conductors 6200 are fixedly connected to the side of the multiple moving spring pieces 3110 facing away from the stationary contact lead-out end 2000, in a one-to-one correspondence.

[0095] like Figures 3 to 6 As shown, the direction of movement of the movable spring 3110 is defined as the second direction D2, and the direction perpendicular to the first direction D1 and the second direction D2 is defined as the third direction D3. The push rod assembly 3200 includes a push rod 3210, a contact bracket 3220, and a stop wall 3230. The push rod 3210 includes a base 3211 and a rod portion 3212, with the base 3211 connected to one axial end of the rod portion 3212. The contact bracket 3220 includes a bottom wall 3221, a first side wall 3222a, and a second side wall 3222b, which are arranged opposite to each other along the third direction D3. One end of the first side wall 3222a and the second side wall 3222b are integrally connected to the two sides of the bottom wall 3221 along the third direction D3, and the other end of the first side wall 3222a and the second side wall 3222b are connected to the stop wall 3230. The stop wall 3230 is located on the side of the moving spring assembly 3100 facing the stationary contact lead-out end 2000. The moving spring assembly 3100 is mounted in the space enclosed by the contact support 3220 and the base 3211 via the elastic component 3300.

[0096] The first sidewall 3222a has a first opening 3228, and the second sidewall 3222b has a second opening 3229. The two ends of the stop wall 3230 along the third direction D3 are respectively inserted into the first opening 3228 and the second opening 3229.

[0097] The contact bracket 3220, the rod 3212 and the base 3211 are connected by injection molding, and the base 3211 covers the bottom wall 3221, one end of the first side wall 3222a and one end of the second side wall 3222b.

[0098] In another embodiment, the two ends of the stop wall 3230 can also be integrally connected to the first side wall 3222a and the second side wall 3222b, respectively.

[0099] The elastic component 3300 is disposed between the moving spring assembly 3100 and the base 3211, and is used to apply an elastic force to the moving spring assembly 3100 toward the stop wall 3230 to provide contact pressure.

[0100] Understandably, the elastic component 3300 can be used in the flexible support spring assembly 3100 to provide contact pressure.

[0101] When there are multiple movable reeds 3110, the multiple movable reeds 3110 are arranged side by side along the third direction D3.

[0102] Please continue reading. Figures 3 to 6The yoke plate 1200 has a second through hole 1210, which extends through two opposite sides of the yoke plate 1200 along its thickness direction and communicates with the contact chamber 1001 of the contact container 1000. A rod portion 3212 is axially movably inserted through the second through hole 1210. A base 3211 at one axial end of the rod portion 3212 is located within the contact chamber 1001.

[0103] The sealing unit 40 also includes a metal cover 5000, which is connected to the side of the yoke plate 1200 facing away from the insulating cover 1100, and the metal cover 5000 covers the second through hole 1210 on the yoke plate 1200. The metal cover 5000 and the yoke plate 1200 form a cavity for accommodating the stationary iron core 4300 and the moving iron core 4400 of the magnetic circuit section 4000.

[0104] Return to reference Figure 1 The coil unit 20 includes a coil frame 21 and a coil 22. The coil frame 21 is a hollow cylindrical shape and is made of insulating material. A metal cover 5000 is inserted inside the coil frame 21. The coil 22 surrounds the coil frame 21.

[0105] like Figures 3 to 6 As shown, the magnetic circuit portion 4000 includes a stationary iron core 4300, a moving iron core 4400, and a reset member 4500. The stationary iron core 4300 is fixedly disposed within the metal cover 5000, and a portion of the stationary iron core 4300 extends into the second through hole 1210. The stationary iron core 4300 has a through hole 4310, which is positioned corresponding to the second through hole 1210, for the rod portion 3212 to pass through. The moving iron core 4400 is movably disposed within the metal cover 5000 and is positioned opposite the stationary iron core 4300 along the axial direction of the rod portion 3212. The moving iron core 4400 is connected to the rod portion 3212 and is attracted by the stationary iron core 4300 when the coil 22 is energized. The moving iron core 4400 and the rod portion 3212 can be connected by screwing, riveting, welding, or other methods.

[0106] The reset element 4500 is located inside the metal cover 5000 and is positioned between the stationary iron core 4300 and the moving iron core 4400. It is used to reset the moving iron core 4400 when the coil 22 is de-energized. The reset element 4500 can be a spring and is sleeved on the outside of the rod portion 3212.

[0107] It should be noted that when coil 22 is energized, the stationary iron core 4300 attracts the moving iron core 4400 to move upward, and the moving iron core 4400 can drive the push rod assembly 3200 to move upward via the rod 3212. When the moving spring 3110 contacts the stationary contact lead-out end 2000, the moving spring 3110 is stopped by the stationary contact lead-out end 2000, while the rod 3212 and the base 3211 will continue to move upward until the overtravel is completed.

[0108] During the overtravel process, the base 3211 will compress the elastic component 3300. After being compressed, the elastic component 3300 can provide elastic force to the moving spring assembly 3100 to provide contact pressure.

[0109] Please continue reading. Figure 4 and Figure 6 The relay 1 also includes a first magnetic conductor 6100, which is fixedly connected to the side surface of the stop wall 3230 facing the moving spring assembly 3100, and the first magnetic conductor 6100 is located on the side of the moving spring assembly 3100 facing the stationary contact lead-out end 2000.

[0110] Understandably, when the moving reed 3110 is energized, the first magnetic conductor 6100 is magnetized, thereby forming an attractive force on the moving reed 3110 in the direction of contact closure. This attractive force can resist the electric repulsive force generated by the short-circuit current between the moving reed 3110 and the stationary contact lead-out terminal 2000, preventing the moving reed 3110 and the stationary contact lead-out terminal 2000 from springing apart, thus achieving the purpose of short-circuit protection.

[0111] When the moving spring assembly 3100 includes multiple moving springs 3110 arranged side by side, the number of first magnetic conductors 6100 can be multiple, and the number of first magnetic conductors 6100 corresponds to the number of moving springs 3110. The multiple first magnetic conductors 6100 are respectively located on the side of the multiple moving springs 3110 facing the stationary contact lead-out end 2000.

[0112] Of course, in other embodiments, when the moving spring assembly 3100 includes a plurality of moving springs 3110 arranged side by side, the number of first magnetic conductors 6100 can be one, which spans the plurality of moving springs 3110 in the third direction D3.

[0113] Furthermore, when the moving spring assembly 3100 includes a moving spring 3110 and a second magnetic conductor 6200, the second magnetic conductor 6200 is fixedly connected to the side of the moving spring 3110 facing away from the stationary contact lead-out end 2000. The second magnetic conductor 6200 is used to form a magnetic circuit with the first magnetic conductor 6100.

[0114] The number of second magnetic conductors 6200 corresponds to the number of moving springs 3110. In this embodiment, there are two second magnetic conductors 6200, but this is not a limitation. The two second magnetic conductors 6200 are respectively fixedly connected to the side of the two moving springs 3110 facing away from the stationary contact lead-out end 2000.

[0115] When the two ends of the movable reed 3110 are in contact with a pair of stationary contact leads 2000, current flows through the movable reed 3110, thereby forming a magnetic circuit around the movable reed 3110 between the first magnetic conductor 6100 and the second magnetic conductor 6200. When a short-circuit current passes through the movable reed 3110, an attractive force is generated between the first magnetic conductor 6100 and the second magnetic conductor 6200 along the contact pressure direction. This attractive force can resist the electrodynamic repulsive force generated between the movable reed 3110 and the stationary contact leads 2000 due to the short-circuit current, preventing the movable reed 3110 from springing away from the stationary contact leads 2000.

[0116] It is understandable that the first magnetic conductor 6100 and the second magnetic conductor 6200 can be of a straight or U-shaped structure. The first magnetic conductor 6100 and the second magnetic conductor 6200 can be made of soft magnetic materials such as iron, cobalt, nickel, and their alloys.

[0117] In another embodiment, the first magnetic conductor 6100 may not be mounted on the stop wall 3230 of the push rod assembly 3200, but may be fixed relative to the contact container 1000. In this way, the short-circuit resistance force is transferred to the contact container 1000. Since the contact container 1000 is a stationary component, excessive coil holding force is unnecessary, thereby reducing the power consumption of the relay 1 coil and the size of the relay 1, and improving short-circuit resistance.

[0118] In one specific embodiment, the first magnetic conductor 6100 can be fixedly connected to the ceramic cover 1110 of the contact container 1000.

[0119] In another specific embodiment, the first magnetic conductor 6100 is also fixedly disposed within the contact container 1000 by a fixed bracket (not shown in the figure). Specifically, the fixed bracket is disposed within the contact container 1000 and is fixedly connected to the yoke plate 1200, and the first magnetic conductor 6100 is fixedly connected to the fixed bracket.

[0120] In another embodiment, the distance between the first magnetic conductor 6100 and the second magnetic conductor 6200 can be designed to be variable. Specifically, the distance between the first magnetic conductor 6100 and the second magnetic conductor 6200 can be adjusted according to the magnitude of the current value, thereby changing the magnitude of the magnetic attraction force generated between the first magnetic conductor 6100 and the second magnetic conductor 6200, which can meet the requirements of short circuit resistance and overload interruption.

[0121] Optionally, the first magnetic conductor 6100 may include multiple stacked magnetic sheets. It is understood that by increasing the number of thinner magnetic sheets, the overall thickness of the first magnetic conductor 6100 can be increased. On the one hand, the thinner magnetic sheets can be manufactured using thin strips, resulting in lower material costs and ease of handling. On the other hand, the number of magnetic sheets can be flexibly adjusted according to the magnitude of the short-circuit current.

[0122] Please continue reading. Figure 4 and Figure 6 The moving spring assembly 3100 has a first side surface 3100a and a second side surface 3100b disposed opposite each other along a third direction D3. The first side surface 3100a corresponds to the first side wall 3222a of the contact support 3220, and the second side surface 3100b corresponds to the second side wall 3222b of the contact support 3220.

[0123] When the moving spring assembly 3100 includes a plurality of moving springs 3110 and a plurality of second magnetic conductors 6200, the two outermost second magnetic conductors 6200 among the plurality of second magnetic conductors 6200 have a first side surface 3100a and a second side surface 3100b, respectively.

[0124] In other embodiments, when the moving spring assembly 3100 includes only a plurality of moving springs 3110, the two outermost moving springs 3110 among the plurality of moving springs 3110 have a first side surface 3100a and a second side surface 3100b, respectively.

[0125] like Figure 7 and Figure 8 As shown, the relay 1 in this embodiment of the application further includes an anti-rotation structure 300, which includes a first anti-rotation member 310 and a second anti-rotation member 320. The first anti-rotation member 310 is disposed between the first sidewall 3222a and the first sidewall 3100a, and the second anti-rotation member 320 is disposed between the second sidewall 3222b and the second sidewall 3100b.

[0126] In the relay 1 of this application embodiment, a first anti-rotation member 310 is disposed between a first sidewall 3222a and a first side surface 3100a, and a second anti-rotation member 320 is disposed between a second sidewall 3222b and a second side surface 3100b, such that when the moving spring assembly 3100 rotates relative to the axis of the push rod, the first anti-rotation member 310 and / or the second anti-rotation member 320 can abut against the moving spring assembly 3100 along a third direction D3, so that the moving spring assembly 3100 is clamped between the first anti-rotation member 310 and the second anti-rotation member 320. In this way, the contact friction between the moving spring assembly 3100 and the first sidewall 3222a and the second sidewall 3222b is avoided, which would otherwise generate metallic noise. This significantly reduces the risk of metal particles being generated by the friction between the moving spring assembly 3100 and the contact support 3220, ensuring the reliability of the relay 1 product. It also reduces the amplitude of the rotation of the moving spring assembly 3100 relative to the push rod around the axis of the push rod. Furthermore, it ensures the consistency of the contact position between the moving spring assembly 3100 and the stationary contact lead-out terminal 2000, thus guaranteeing the stability of the contact resistance.

[0127] like Figure 8 As shown, in the first embodiment of this application, both the first anti-rotation member 310 and the second anti-rotation member 320 are sheet-like structures made of flexible material. The first sidewall 3222a has a first inner side surface 3223 facing the moving spring assembly 3100, and the first anti-rotation member 310 is attached to the first inner side surface 3223 or the first side surface 3100a. The second sidewall 3222b has a second inner side surface 3225 facing the moving spring assembly 3100, and the second anti-rotation member 320 is attached to the second inner side surface 3225 or the second side surface 3100b.

[0128] In one embodiment, the flexible material can be a non-metallic material, such as rubber or abrasion-resistant plastic, but is not limited thereto.

[0129] The first anti-rotation component 310 can be attached to the first inner side 3223 or the first side 3100a by welding, bonding or other connection methods, and the second anti-rotation component 320 can be attached to the second inner side 3225 or the second side 3100b by welding, bonding or other connection methods.

[0130] In the embodiments of this application, both the first anti-rotation member 310 and the second anti-rotation member 320 are made of flexible material, which can reduce the wear of the first anti-rotation member 3100 on the moving spring assembly 3100 by the first anti-rotation member 310 and the second anti-rotation member 320 on the second side surface 3100b, and reduce the friction between the first anti-rotation member 310 and the first side surface 3100a and the second anti-rotation member 320, thus avoiding affecting the overtravel process. In addition, the flexible material can also reduce the deflection force of the moving spring assembly 3100 relative to the contact support 3220, thereby reducing the rotation amplitude of the moving spring assembly 3100, and reducing the frictional resistance and mutual friction noise between the moving spring assembly 3100 and the contact support 3220.

[0131] Of course, in other embodiments, the first anti-rotation member 310 may also be connected to the first side 3100a, and the second anti-rotation member 320 may also be connected to the second side 3100b.

[0132] Furthermore, throughout the entire movement of the push rod assembly 3200, the first anti-rotation member 310 is always in contact with the first sidewall 3222a and the first side surface 3100a, and the second anti-rotation member 320 is always in contact with the second sidewall 3222b and the second side surface 3100b. Specifically, before the movable spring 3110 contacts the stationary contact lead-out end 2000, the first anti-rotation member 310 is in contact with the first sidewall 3222a and the first side surface 3100a, and the second anti-rotation member 320 is in contact with the second sidewall 3222b and the second side surface 3100b; in the initial stage of overtravel (i.e., when the movable spring 3110 just contacts the stationary contact lead-out end 2000), the first anti-rotation member 310 is in contact with the first sidewall 3222a and the first side surface 3100a, and the second anti-rotation member 320 is in contact with the second sidewall 3222b and the second side surface 3100b. During the overtravel end phase (i.e., when the moving iron core 4400 contacts the stationary iron core 4300), the first anti-rotation member 310 remains abutted between the first sidewall 3222a and the first side surface 3100a, and the second anti-rotation member 320 remains abutted between the second sidewall 3222b and the second side surface 3100b; furthermore, at any position between the overtravel initial phase and the overtravel end phase, the first anti-rotation member 310 also abuts between the first sidewall 3222a and the first side surface 3100a, and the second anti-rotation member 320 also abuts between the second sidewall 3222b and the second side surface 3100b. Thus, the moving spring assembly 3100 remains stable throughout the entire movement of the moving assembly 3000, reducing the amplitude of rotation of the moving spring assembly 3100 relative to the push rod about the axis of the push rod.

[0133] like Figure 9 and Figure 10 As shown, the similarities between the moving component 3000 of the second embodiment and the moving component 3000 of the first embodiment will not be repeated here. The differences are as follows: The contact bracket 3220 of the push rod assembly 3200 is inverted U-shaped, including a top wall 3227 and two side walls (the two side walls are respectively equivalent to the first side wall 3222a and the second side wall 3222b in the first embodiment above). One end of each of the two side walls is integrally connected to the two sides of the top wall 3227 along the third direction D3, and the other end of each of the two side walls is snapped into the base 3211.

[0134] like Figures 11 to 14 The similarities between the moving component 3000 of the third embodiment and the moving component 3000 of the first embodiment will not be repeated here. The differences are as follows: Both the first anti-rotation member 310 and the second anti-rotation member 320 are spring sheets. The first anti-rotation member 310 is pressed between the first sidewall 3222a and the first side surface 3100a of the moving spring assembly 3100, providing a first elastic force to the moving spring assembly 3100. The second anti-rotation member 320 is pressed between the second sidewall 3222b and the second side surface 3100b of the moving spring assembly 3100, providing a second elastic force to the moving spring assembly 3100. The first elastic force and the second elastic force are in opposite directions.

[0135] In the embodiments of this application, the first anti-rotation member 310 and the second anti-rotation member 320 are both spring sheets. The elastic force provided by the spring sheets can absorb the deflection of the moving spring assembly 3100, reduce the deflection force between the moving spring assembly 3100 and the first sidewall 3222a and the second sidewall 3222b of the contact support 3220, and reduce the frictional resistance and frictional noise between the moving spring assembly 3100 and the contact support 3220.

[0136] like Figures 12 to 14 As shown, both the first anti-rotation component 310 and the second anti-rotation component 320 include a connecting portion 330 and a spring portion 340; the two connecting portions 330 are respectively connected to the first sidewall 3222a and the second sidewall 3222b, and the two spring portions 340 extend from the two connecting portions 330 in a direction away from the stationary contact lead-out end 2000; the two spring portions 340 are used to provide a first elastic force and a second elastic force to the moving spring assembly 3100, respectively.

[0137] The connecting part 330 includes hooks 331, and the two hooks 331 are respectively attached to the lower edge of the first opening 3228 and the lower edge of the second opening 3229.

[0138] like Figures 15 to 17 As shown, the similarities between the moving component 3000 of the fourth embodiment and the moving component 3000 of the third embodiment will not be repeated here. The differences are as follows: The anti-rotation structure 300 also includes a transition member 360, one end of the first anti-rotation member 310 and one end of the second anti-rotation member 320 are integrally connected to the two ends of the transition member 360 along the third direction D3. The transition member 360 has a central hole 361, and the elastic component 3300 passes through the central hole 361.

[0139] In this embodiment of the application, the anti-rotation structure 300 also has a transition member 360, which is integrally connected with the first anti-rotation member 310 and the second anti-rotation member 320, thereby improving the structural strength of the anti-rotation structure 300 and preventing the first anti-rotation member 310 and the second anti-rotation member 320 from shaking.

[0140] like Figure 18As shown, in another embodiment, both the first anti-rotation member 310 and the second anti-rotation member 320 of the anti-rotation structure 300 are provided with slots 350. The extending direction of the slots 350 is approximately parallel to the second direction D2.

[0141] like Figure 19 As shown, in another embodiment, both the first anti-rotation member 310 and the second anti-rotation member 320 of the anti-rotation structure 300 are provided with slots 350. The extending direction of the slots 350 is inclined relative to the second direction D2.

[0142] In this embodiment of the application, by providing slots 350 on the first anti-rotation member 310 and the second anti-rotation member 320, the flexibility of the first anti-rotation member 310 and the second anti-rotation member 320 is improved. On the one hand, the elastic force of the first anti-rotation member 310 and the second anti-rotation member 320 is reduced, so that the deflection force of the dynamic spring assembly 3100 can be better absorbed. On the other hand, the high rigidity of the first anti-rotation member 310 and the second anti-rotation member 320 is avoided from causing wear to the dynamic spring assembly 3100.

[0143] like Figures 20 to 22 As shown, the similarities between the moving component 3000 of the fifth embodiment and the moving component 3000 of the fourth embodiment will not be repeated here, but the differences are as follows: Each connecting part 330 includes a snap-fit ​​structure 332, and the snap-fit ​​structures 332 of the two connecting parts 330 are respectively snapped into the first opening 3228 and the second opening 3229.

[0144] like Figure 22 As shown, the snap-fit ​​structure 332 includes two connecting pieces 332b, which are connected to the spring piece 340. One of the connecting pieces 332b is provided with a hook 332a.

[0145] like Figure 23 As shown, the snap-fit ​​structure 332 includes three connecting pieces 332b arranged sequentially along the third direction D3, with a gap between adjacent connecting pieces 332b. The two outermost connecting pieces 332b are each provided with a hook 332a.

[0146] like Figure 24 As shown, the snap-fit ​​structure 332 includes a connecting piece 332b, which has a hook 332a at one end along the third direction D3.

[0147] like Figures 25 to 28 As shown, the similarities between the moving component 3000 of the sixth embodiment and the moving component 3000 of the fifth embodiment will not be repeated here, but the differences are as follows: The snap-fit ​​structure 332 is a sheet-like structure, and the two snap-fit ​​structures 332 are respectively snapped into the first opening 3228 and the second opening 3229.

[0148] The first sidewall 3222a is also provided with a first connecting hole 410, and the second sidewall 3222b is also provided with a second connecting hole 420. Each connecting part 330 also includes a protrusion 333, and the protrusions 333 of the two connecting parts 330 extend into the first connecting hole 410 and the second connecting hole 420 respectively, and are respectively interference-fitted with the first connecting hole 410 and the second connecting hole 420.

[0149] like Figure 27 As shown, the cross-sectional shape of the convex hull 333 is circular.

[0150] like Figure 29 As shown, in another embodiment, the cross-sectional shape of the convex hull 333 can also be elliptical. Of course, in other embodiments, the cross-sectional shape of the convex hull 333 can also be rectangular, triangular, or other shapes.

[0151] like Figures 30 to 32 As shown, the similarities between the moving component 3000 of the seventh embodiment and the moving component 3000 of the fifth embodiment will not be repeated here, but the differences are as follows: Both the first sidewall 3222a and the second sidewall 3222b are provided with protruding claws 600. Each connecting part 330 includes a collar 334, and the collars 334 of the two connecting parts 330 are respectively sleeved on the outer periphery of the protruding claw 600 of the first sidewall 3222a and the outer periphery of the protruding claw 600 of the second sidewall 3222b.

[0152] In this embodiment of the application, the end of the first sidewall 3222a away from the base 3211 is provided with two protruding claws 600 spaced apart along the third direction D3, and the first anti-rotation member 310 is provided with two collars 334, which are respectively sleeved on the outer periphery of the two protruding claws 600 of the first sidewall 3222a.

[0153] The second sidewall 3222b is provided with two protruding claws 600 spaced apart along the third direction D3 at one end away from the base 3211. The second anti-rotation component 320 is provided with two collars 334, and the two collars 334 of the second anti-rotation component 320 are respectively sleeved on the outer periphery of the two protruding claws 600 of the second sidewall 3222b.

[0154] Furthermore, in the embodiments of this application, the movable spring assembly 3100 includes a movable spring 3110 and two second magnetic conductors 6200. The movable spring 3110 is provided with a through hole, and each second magnetic conductor 6200 has a U-shaped structure, and the two adjacent sides of the two U-shaped structures are inserted into the same through hole.

[0155] like Figures 33 to 35 As shown, the similarities between the moving component 3000 of the eighth embodiment and the moving component 3000 of the third embodiment will not be repeated here. The differences are as follows: The connecting portion 330 of the first anti-rotation member 310 is riveted to the first inner surface 3223 of the first side wall 3222a facing the moving spring assembly 3100, and the connecting portion 330 of the second anti-rotation member 320 is riveted to the second inner surface 3225 of the second side wall 3222b facing the moving spring assembly 3100.

[0156] In another embodiment, the connecting portion 330 of the first anti-rotation member 310 is welded to the first inner surface 3223 of the first sidewall 3222a facing the moving spring assembly 3100, and the connecting portion 330 of the second anti-rotation member 320 is welded to the second inner surface 3225 of the second sidewall 3222b facing the moving spring assembly 3100.

[0157] In addition, in the embodiments of this application, the anti-rotation structure 300 also includes a transition member 360, one end of the first anti-rotation member 310 and one end of the second anti-rotation member 320 are integrally connected to the two ends of the transition member 360 along the third direction D3.

[0158] like Figures 36 to 38 As shown, the similarities between the moving component 3000 of the ninth embodiment and the moving component 3000 of the first embodiment will not be repeated here. The differences are as follows: The anti-rotation structure 300 also includes a transition member 360. One end of the first anti-rotation member 310 and one end of the second anti-rotation member 320 are integrally connected to both ends of the transition member 360 along the third direction D3. The transition member 360 is fixedly connected to the dynamic spring assembly 3100. One end of the elastic component 3300 abuts against the base 3211, and the other end abuts against the transition member 360.

[0159] As an example, the transition piece 360 ​​is fixedly connected to the second magnetic conductor 6200. Further, the transition piece 360 ​​and the second magnetic conductor 6200 can be connected by riveting, welding, or other methods, but are not limited to these.

[0160] like Figures 39 to 41 As shown, the similarities between the moving component 3000 of the tenth embodiment and the moving component 3000 of the ninth embodiment will not be repeated here. The differences are as follows: The transition member 360 is disposed between the stop wall 3230 and the first magnetic conductor 6100, and is fixedly connected to the stop wall 3230 and the first magnetic conductor 6100. That is to say, when assembling the push rod assembly 3200, the stop wall 3230, the first magnetic conductor 6100 and the anti-rotation structure 300 can be fixedly connected as a whole, and then the whole can be connected to the contact bracket 3220.

[0161] Furthermore, the stop wall 3230, the first magnetic conductor 6100 and the transition piece 360 ​​of the anti-rotation structure 300 can be fixedly connected by riveting, welding or other means, but are not limited thereto.

[0162] like Figure 42 As shown, the similarities between the moving component 3000 of the eleventh embodiment and the moving component 3000 of the first embodiment will not be repeated here. The differences are as follows: Both the first anti-rotation member 310 and the second anti-rotation member 320 are spring clips. The first anti-rotation member 310 is integrally connected to the first sidewall 3222a, and the second anti-rotation member 320 is integrally connected to the second sidewall 3222b. The first anti-rotation member 310 is used to provide a first elastic force to the moving spring assembly 3100, and the second anti-rotation member 320 is used to provide a second elastic force to the moving spring assembly 3100.

[0163] Furthermore, the first sidewall 3222a also has a third opening 510, and the second sidewall 3222b also has a fourth opening 520. The first anti-rotation member 310 is integrally connected to the upper edge of the third opening 510, and the second anti-rotation member 320 is integrally connected to the upper edge of the fourth opening 520.

[0164] like Figure 43 As shown, the similarities between the moving component 3000 of the twelfth embodiment and the moving component 3000 of the eleventh embodiment will not be repeated here, but the differences are as follows: The first anti-rotation component 310 is integrally connected to the lower edge of the third opening 510, and the second anti-rotation component 320 is integrally connected to the lower edge of the fourth opening 520.

[0165] It should be noted that in the third to twelfth embodiments described above, both the first anti-rotation component 310 and the second anti-rotation component 320 can be provided with a slot 350.
