Description

Technical Field

[0001] The present application relates to the technical field of electronic control devices, and in particular to a relay. Background Art

[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). It is usually used in automatic control circuits. A relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] A high-voltage DC relay is a type of relay. A high-voltage DC relay in the prior art includes a pair of static contact lead-out terminals, a dynamic component, a coil unit, and a magnetic circuit portion. The dynamic component includes a dynamic spring component, a push rod component, and an elastic component. The dynamic spring component is mounted on the push rod component through the elastic component. The magnetic circuit portion includes a static iron core and a dynamic iron core. The static iron core is fixedly arranged in the relay, and the dynamic iron core is connected to the push rod component. When the coil unit is energized, the static iron core can generate a magnetic attraction and attract the dynamic iron core to move, thereby driving the push rod component to move together with the dynamic spring component to achieve contact closure.

[0004] However, during the operation of the relay, the movable spring assembly is prone to rotate relative to the push rod around the axis of the push rod, resulting in contact and friction between the movable spring assembly and the contact bracket of the push rod assembly, thereby generating a large metal noise; further, with the friction loss between the movable spring assembly and the contact bracket, the deflection angle of the movable spring assembly will become larger and larger, thereby affecting the contact position between the movable spring assembly and the static contact lead-out terminal, resulting in unstable contact resistance; in addition, metal particles are easily generated after the friction between the movable spring assembly and the contact bracket. After the metal particles fall on the contact surface of the contact, it is easy to cause the contact resistance to increase or even cause the relay to fail to conduct. Summary of the invention

[0098] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0099] like Figure 1As shown, the relay 1 of the embodiment of the present application includes a housing 10, a coil unit 20, an arc extinguishing unit 30 and a sealing unit 40. The sealing unit 40 is arranged in the housing 10, and the top of the static contact lead-out end of the sealing unit 40 is exposed to the outer surface of the housing 10 through the exposure hole 11a of the housing 10. The coil unit 20 and the arc extinguishing unit 30 are both arranged in the housing 10.

[0100] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0101] As an example, the housing 10 includes a first shell 11 and a second shell 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 the embodiment of the present application, the exposure hole 11a is provided in the first shell 11.

[0102] The arc extinguishing unit 30 is used to extinguish the arc generated between the static contact lead-out end of the sealing unit 40 and the moving reed.

[0103] As an example, the arc extinguishing unit 30 includes two arc extinguishing magnets 31. The arc extinguishing magnets 31 may be permanent magnets, and each arc extinguishing magnet 31 may be substantially rectangular. The two arc extinguishing magnets 31 are respectively arranged on both sides of the sealing unit 40 and are arranged opposite to each other along the length direction of the moving spring piece.

[0104] By providing two arc extinguishing magnets 31 arranged opposite to each other, a magnetic field can be formed around the static contact lead-out terminal and the movable reed piece. Therefore, the arc generated between the static contact lead-out terminal and the movable reed piece will be elongated in a direction away from each other by the effect of the magnetic field, thereby achieving arc extinguishing.

[0105] The arc extinguishing unit 30 also includes two yoke iron clamps 32, and the two yoke iron clamps 32 are arranged corresponding to the positions of the two arc extinguishing magnets 31. In addition, the two yoke iron clamps 32 surround the sealing unit 40 and the two arc extinguishing magnets 31. By designing that the yoke iron clamps 32 surround the arc extinguishing magnets 31, it is possible to prevent the magnetic field generated by the arc extinguishing magnets 31 from diffusing outward and affecting the arc extinguishing effect. The yoke iron clamps 32 are made of soft magnetic material. Soft magnetic materials may include but are not limited to iron, cobalt, nickel, and alloys thereof.

[0106] like Figures 2 to 6 As shown, the sealing unit 40 includes a contact container 1000 , a pair of stationary contact lead terminals 2000 , a moving assembly 3000 and a magnetic circuit portion 4000 .

[0107] It should be noted that the contact container 1000 is a stationary component, which is used to accommodate the contact group and is mainly a housing and has a chamber. In addition, the contact container 1000 can be formed by connecting multiple components in a predetermined assembly manner.

[0108] The contact container 1000 has a contact chamber 1001 therein. The contact container 1000 may include an insulating cover 1100 and a yoke plate 1200 . The insulating cover 1100 is disposed on one side surface of the yoke plate 1200 . The insulating cover 1100 and the yoke plate 1200 together enclose the contact chamber 1001 .

[0109] The insulating cover 1100 includes a ceramic cover 1110 and a frame piece 1120. The ceramic cover 1110 is connected to the yoke iron plate 1200 through the frame piece 1120. The frame piece 1120 can be a metal piece with an annular structure, such as an iron-nickel alloy, and one end of the frame piece 1120 is connected to the opening edge of the ceramic cover 1110, for example, by laser welding, brazing, resistance welding, gluing, etc. The other end of the frame piece 1120 is connected to the yoke iron plate 1200, which can also be done by laser welding, brazing, resistance welding, gluing, etc. A frame piece 1120 is arranged between the ceramic cover 1110 and the yoke iron plate 1200 to facilitate the connection between the ceramic cover 1110 and the yoke iron plate 1200.

[0110] The contact container 1000 also has a pair of first through holes 1002, and the first through holes 1002 are connected to the contact chamber 1001. The first through holes 1002 are used for the static contact lead-out terminal 2000 to pass through. In the embodiment of the present application, the first through holes 1002 are opened on the ceramic cover 1110.

[0111] A pair of static contact lead-out terminals 2000 are connected to the ceramic cover 1110 of the contact container 1000, and at least a portion of each static contact lead-out terminal 2000 is located in the contact chamber 1001. One of the pair of static contact lead-out terminals 2000 serves as a terminal for current inflow, and the other serves as a terminal for current outflow.

[0112] A pair of static contact lead-out terminals 2000 are disposed in a pair of first through holes 1002 in a one-to-one correspondence, and are connected to the ceramic cover 1110 , for example, by welding.

[0113] The bottom of the static contact lead-out terminal 2000 serves as a static contact, and the static contact may be integrally or separately arranged at the bottom of the static contact lead-out terminal 2000 .

[0114] Please continue reading Figures 3 to 6The movable assembly 3000 includes a movable spring assembly 3100, a push rod assembly 3200 and an elastic assembly 3300. The movable spring assembly 3100 is disposed in the insulating cover 1100 and is mounted on the push rod assembly 3200 through the elastic assembly 3300. The two ends of the movable spring assembly 3100 along the first direction D1 are used to contact or separate with a pair of static contact lead-out terminals 2000 respectively. The first direction D1 is the arrangement direction of the pair of static contact lead-out terminals 2000.

[0115] It should be noted that, if a pair of static contact lead terminals 2000 and a movable spring assembly 3100 are regarded as a set of combinations, then the relay of the embodiment of the present application may include multiple sets of combinations.

[0116] The dynamic spring assembly 3100 may include a dynamic spring piece 3110 , and two ends of the dynamic spring piece 3110 along the first direction D1 are used to contact or separate from a pair of static contact lead-out terminals 2000 , respectively.

[0117] It is understandable that the number of the movable reed 3110 can be one or more.

[0118] Each movable spring piece 3110 may include a movable spring body and movable contacts disposed at both ends of the movable spring body. The movable contacts may be separate parts and connected to the movable spring body. Of course, the movable contacts may also be integrally formed on the movable spring body.

[0119] In the embodiment of the present application, the dynamic spring assembly 3100 includes two dynamic spring pieces 3110 arranged side by side. One end of the two dynamic spring pieces 3110 is used to contact or separate with the static contact of one of the static contact lead-out terminals 2000, and the other end of the two dynamic spring pieces 3110 is used to contact or separate with the static contact of the other static contact lead-out terminal 2000. Further, one end of the two dynamic spring pieces 3110 forms two contact points with one of the static contact lead-out terminals 2000, and the other end of the two dynamic spring pieces 3110 forms two contact points with the other static contact lead-out terminal 2000.

[0120] In other embodiments, the number of the movable reed pieces 3110 may also be one, three, four, five, etc.

[0121] It can be understood that the dynamic spring assembly 3100 includes a plurality of dynamic spring pieces 3110, and the two ends of the plurality of dynamic spring pieces 3110 along the first direction D1 are respectively in contact with or separated from a pair of static contact lead-out terminals. Since the plurality of dynamic spring pieces 3110 will not restrict each other, the two ends of the plurality of dynamic spring pieces 3110 along the first direction D1 are respectively in contact with a pair of static contact lead-out terminals 2000 to form a reliable parallel circuit. The number of contacts formed by the plurality of dynamic spring pieces 3110 and a static contact lead-out terminal 2000 is greater than or equal to two, achieving a shunting effect. In addition, according to the principle that the magnitude of the electric repulsive force is proportional to the square of the current, the magnitude of the electric repulsive force of each contact is significantly reduced, which is conducive to the improvement of the short-circuit resistance and the reliability of the relay.

[0122] Furthermore, the movable spring assembly 3100 may further include a second magnetic conductor 6200, which is fixedly connected to a side of the movable spring piece 3110 facing away from the static contact lead-out end 2000. The function of the second magnetic conductor 6200 will be described below.

[0123] The number of the movable spring pieces 3110 and the number of the second magnetizers 6200 included in the movable spring assembly 3100 are corresponding. Specifically, when the number of the movable spring piece 3110 is one, the number of the second magnetizer 6200 is also one; when the number of the movable spring pieces 3110 is multiple (including two), the number of the second magnetizers 6200 is also multiple. The multiple second magnetizers 6200 are fixedly connected to the side of the multiple movable spring pieces 3110 facing away from the static contact lead-out terminal 2000 in a one-to-one correspondence.

[0124] like Figures 3 to 6 As shown, the moving direction 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, and the base 3211 is connected to an 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, and the first side wall 3222a and the second side wall 3222b 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 respectively 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 disposed on one side of the movable spring assembly 3100 facing the static contact lead-out terminal 2000. The movable spring assembly 3100 is installed in a space enclosed by the contact support 3220 and the base 3211 through the elastic assembly 3300.

[0125] The first side wall 3222a has a first opening 3228, and the second side wall 3222b has a second opening 3229. 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.

[0126] The contact support 3220 , the rod portion 3212 and the base 3211 are connected by injection molding, and the base 3211 covers the bottom wall 3221 and one end of the first side wall 3222 a and one end of the second side wall 3222 b .

[0127] In another embodiment, both ends of the stopping wall 3230 may also be integrally connected to the first side wall 3222a and the second side wall 3222b respectively.

[0128] The elastic component 3300 is disposed between the dynamic spring component 3100 and the base 3211 , and is used to apply an elastic force to the dynamic spring component 3100 to move toward the stop wall 3230 , so as to provide contact pressure.

[0129] It is understandable that the elastic component 3300 can be used to flexibly support the dynamic spring component 3100 to provide contact pressure.

[0130] When there are multiple movable spring pieces 3110 , the multiple movable spring pieces 3110 are arranged side by side along the third direction D3 .

[0131] Please continue reading Figures 3 to 6 The yoke plate 1200 has a second through hole 1210, which penetrates two opposite sides of the yoke plate 1200 along the thickness direction of the yoke plate 1200, and the second through hole 1210 is connected to the contact chamber 1001 of the contact container 1000. The rod portion 3212 is movably disposed in the second through hole 1210 along the axial direction. The base 3211 at one axial end of the rod portion 3212 is disposed in the contact chamber 1001.

[0132] The sealing unit 40 further 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 enclose a chamber for accommodating the static iron core 4300 and the moving iron core 4400 of the magnetic circuit part 4000.

[0133] Return to Reference Figure 1 The coil unit 20 includes a coil frame 21 and a coil 22. The coil frame 21 is hollow and cylindrical and is made of insulating material. The metal cover 5000 is inserted into the coil frame 21. The coil 22 surrounds the coil frame 21.

[0134] like Figures 3 to 6As shown, the magnetic circuit part 4000 includes a static iron core 4300, a moving iron core 4400 and a reset member 4500. The static iron core 4300 is fixedly arranged in the metal cover 5000, and part of the static iron core 4300 extends into the second through hole 1210. The static iron core 4300 has a through hole 4310, and the through hole 4310 is arranged corresponding to the position of the second through hole 1210, for the rod portion 3212 to pass therethrough. The moving iron core 4400 is movably arranged in the metal cover 5000, and is arranged opposite to the static 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 used to be attracted by the static 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.

[0135] The reset member 4500 is located inside the metal cover 5000 and is disposed between the static iron core 4300 and the moving iron core 4400, and is used to reset the moving iron core 4400 when the coil 22 is powered off. The reset member 4500 can be a spring and is sleeved on the outside of the rod 3212.

[0136] It should be noted that when the coil 22 is energized, the static 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 through the rod portion 3212. When the moving spring piece 3110 contacts the static contact lead-out end 2000, the moving spring piece 3110 is stopped by the static contact lead-out end 2000, while the rod portion 3212 and the base 3211 will continue to move upward until the overtravel is completed.

[0137] During the overtravel process, the base 3211 will squeeze the elastic component 3300. After being squeezed, the elastic component 3300 can provide elastic force to the dynamic spring component 3100 to provide contact pressure.

[0138] Please continue reading Figure 4 and Figure 6 The relay 1 further comprises a first magnetic conductor 6100 , which is fixedly connected to a surface of the stop wall 3230 on one side facing the movable spring assembly 3100 , and is located on a side of the movable spring assembly 3100 facing the static contact lead-out terminal 2000 .

[0139] It can be understood that when the moving reed 3110 is energized, the first magnetic conductor 6100 is magnetized, thereby forming a suction force on the moving reed 3110 in the direction of contact closure, and the suction force can resist the electromotive repulsion between the moving reed 3110 and the static contact lead-out terminal 2000 due to the short-circuit current, thereby preventing the moving reed 3110 and the static contact lead-out terminal 2000 from bouncing apart, thereby achieving the purpose of resisting short circuit.

[0140] In which, when the dynamic spring assembly 3100 includes multiple dynamic spring pieces 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 dynamic spring pieces 3110, and the multiple first magnetic conductors 6100 are respectively located on one side of the multiple dynamic spring pieces 3110 facing the static contact lead-out end 2000.

[0141] Of course, in other embodiments, when the dynamic spring assembly 3100 includes a plurality of dynamic spring pieces 3110 arranged side by side, the number of the first magnetic conductor 6100 may be one, and the first magnetic conductor 6100 spans across the plurality of dynamic spring pieces 3110 in the third direction D3.

[0142] Further, when the dynamic spring assembly 3100 includes the dynamic spring piece 3110 and the second magnetic conductor 6200, the second magnetic conductor 6200 is fixedly connected to the side of the dynamic spring piece 3110 facing away from the static contact lead-out end 2000. The second magnetic conductor 6200 is used to form a magnetic circuit with the first magnetic conductor 6100.

[0143] The number of the second magnetic conductors 6200 corresponds to the number of the movable spring pieces 3110. In the embodiment of the present application, the number of the second magnetic conductors 6200 is two, but not limited thereto. The two second magnetic conductors 6200 are respectively fixedly connected to the side of the two movable spring pieces 3110 facing away from the static contact lead-out end 2000.

[0144] When both ends of the moving spring piece 3110 are in contact with a pair of static contact lead-out terminals 2000, current flows through the moving spring piece 3110, thereby forming a magnetic conductive loop around the moving spring piece 3110 between the first magnetic conductive body 6100 and the second magnetic conductive body 6200. When the short-circuit current passes through the moving spring piece 3110, an attractive force is generated between the first magnetic conductive body 6100 and the second magnetic conductive body 6200 in the direction of contact pressure, and the attractive force can resist the electromotive repulsion force generated by the short-circuit current between the moving spring piece 3110 and the static contact lead-out terminals 2000, thereby preventing the moving spring piece 3110 and the static contact lead-out terminals 2000 from being bounced apart.

[0145] It is understandable that the first magnetic conductor 6100 and the second magnetic conductor 6200 may be a straight-line structure or a U-shaped structure. The first magnetic conductor 6100 and the second magnetic conductor 6200 may be made of soft magnetic materials such as iron, cobalt, nickel, and alloys thereof.

[0146] In another embodiment, the first magnetic conductor 6100 may not be installed 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 suction force for resisting short circuit is transferred to the contact container 1000. Since the contact container 1000 is a stationary component, there is no need for excessive coil holding force, thereby reducing the power consumption of the coil of the relay 1 and the volume of the relay 1, and improving the short circuit resistance.

[0147] In a specific implementation, the first magnetic conductor 6100 may be fixedly connected to the ceramic cover 1110 of the contact container 1000 .

[0148] In another specific embodiment, the first magnetizer 6100 is also fixed in the contact container 1000 through a fixing bracket (not shown in the figure). Specifically, the fixing bracket is arranged in the contact container 1000 and fixedly connected to the yoke plate 1200, and the first magnetizer 6100 is fixedly connected to the fixing bracket.

[0149] In another embodiment, the distance between the first magnetizer 6100 and the second magnetizer 6200 can be designed to be variable. Specifically, the distance between the first magnetizer 6100 and the second magnetizer 6200 can be adjusted according to the magnitude of the current value, thereby changing the magnitude of the magnetic attraction generated between the first magnetizer 6100 and the second magnetizer 6200, while meeting the requirements of short circuit resistance and overload disconnection.

[0150] Optionally, the first magnetic conductor 6100 may include a plurality of stacked magnetic conductors. It is understood that by increasing the number of thinner magnetic conductors, the overall thickness of the first magnetic conductor 6100 may be increased. On the one hand, the magnetic conductors are thinner and can be made of thin strips, so the material cost is low and easy to operate. On the other hand, the number of magnetic conductors can be flexibly adjusted according to the size of the short-circuit current.

[0151] Please continue reading Figure 4 and Figure 6 The dynamic spring assembly 3100 has a first side surface 3100a and a second side surface 3100b disposed opposite to 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.

[0152] When the dynamic spring assembly 3100 includes a plurality of dynamic spring pieces 3110 and a plurality of second magnetic conductors 6200 , two second magnetic conductors 6200 located on the outermost sides of the plurality of second magnetic conductors 6200 respectively have a first side surface 3100 a and a second side surface 3100 b .

[0153] In other embodiments, when the dynamic spring assembly 3100 includes only a plurality of dynamic spring pieces 3110 , two dynamic spring pieces 3110 located at the outermost sides of the plurality of dynamic spring pieces 3110 respectively have a first side surface 3100 a and a second side surface 3100 b .

[0154] like Figure 7 and Figure 8As shown, the relay 1 of the embodiment of the present application also includes an anti-rotation structure 300, the anti-rotation structure 300 includes a first anti-rotation component 310 and a second anti-rotation component 320, the first anti-rotation component 310 is arranged between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 is arranged between the second side wall 3222b and the second side surface 3100b.

[0155] In the relay 1 of the embodiment of the present application, the first anti-rotation member 310 is arranged between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation member 320 is arranged between the second side wall 3222b and the second side surface 3100b, so that when the dynamic 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 push against the dynamic spring assembly 3100 along the third direction D3, so that the dynamic spring assembly 3100 is clamped between the first anti-rotation member 310 and the second anti-rotation member 320. The movable spring assembly 3100 is prevented from generating metal noise due to contact and friction with the first side wall 3222a and the second side wall 3222b, and the risk of generating metal particles due to friction between the movable spring assembly 3100 and the contact bracket 3220 is significantly reduced, thereby ensuring the reliability of the operation of the relay 1 product and reducing the amplitude of rotation of the movable spring assembly 3100 relative to the push rod around the axis of the push rod. Furthermore, the consistency of the contact position between the movable spring assembly 3100 and the static contact lead-out terminal 2000 is ensured, thereby ensuring the stability of the contact resistance.

[0156] like Figure 8 As shown, in the first embodiment of the present application, the first anti-rotation member 310 and the second anti-rotation member 320 are both sheet structures made of flexible materials. The first side wall 3222a has a first inner side surface 3223 facing the dynamic 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 side wall 3222b has a second inner side surface 3225 facing the dynamic 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.

[0157] In one embodiment, the flexible material may be a non-metallic material, such as rubber or wear-resistant plastic, but is not limited thereto.

[0158] The first anti-rotation component 310 can be attached to the first inner side surface 3223 or the first side surface 3100a by welding, bonding or other connection methods, and the second anti-rotation component 320 can be attached to the second inner side surface 3225 or the second side surface 3100b by welding, bonding or other connection methods.

[0159] In the embodiment of the present application, the first anti-rotation member 310 and the second anti-rotation member 320 are both made of flexible materials, which can reduce the wear of the first anti-rotation member 310 and the second anti-rotation member 320 on the dynamic spring assembly 3100, and reduce the friction between the first anti-rotation member 310 and the first side 3100a and between the second anti-rotation member 320 and the second side 3100b, so as to avoid affecting the overtravel process. In addition, the flexible material can also reduce the deflection force of the dynamic spring assembly 3100 relative to the contact bracket 3220, thereby reducing the rotation amplitude of the dynamic spring assembly 3100, and reducing the friction resistance and mutual friction noise between the dynamic spring assembly 3100 and the contact bracket 3220.

[0160] Of course, in other embodiments, the first anti-rotation component 310 may also be connected to the first side surface 3100a, and the second anti-rotation component 320 may also be connected to the second side surface 3100b.

[0161] Furthermore, during the entire movement of the push rod assembly 3200, the first anti-rotation component 310 always abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 always abuts between the second side wall 3222b and the second side surface 3100b. Specifically, before the movable spring piece 3110 has not yet contacted the static contact lead-out terminal 2000, the first anti-rotation component 310 abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 abuts between the second side wall 3222b and the second side surface 3100b; in the initial stage of overtravel (i.e., when the movable spring piece 3110 has just contacted the static contact lead-out terminal 2000), the first anti-rotation component 310 abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 abuts between the second side wall 3222b and the second side surface 3100b. At the end of the overtravel (i.e. when the moving iron core 4400 contacts the static iron core 4300), the first anti-rotation component 310 still abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 still abuts between the second side wall 3222b and the second side surface 3100b; and at any position between the initial stage of the overtravel and the end of the overtravel, the first anti-rotation component 310 also abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 also abuts between the second side wall 3222b and the second side surface 3100b. In this way, the dynamic spring assembly 3100 can remain stable throughout the entire process of the movement of the dynamic assembly 3000, reducing the amplitude of the dynamic spring assembly 3100 rotating relative to the push rod around the axis of the push rod.

[0162] like Fig. 9 and Fig.10 As shown, the similarities between the moving assembly 3000 of the second embodiment of the present application and the moving assembly 3000 of the first embodiment are not repeated here, and the difference lies in that:

[0163] The contact bracket 3220 of the push rod assembly 3200 is an inverted U-shape, 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 of the above-mentioned first embodiment), one end of the two side walls are respectively integrally connected to the two side edges of the top wall 3227 along the third direction D3, and the other ends of the two side walls are respectively clamped with the base 3211.

[0164] like Figures 11 to 14 The similarities between the moving assembly 3000 of the third embodiment of the present application and the moving assembly 3000 of the first embodiment are not repeated here, and the difference lies in that:

[0165] The first anti-rotation member 310 and the second anti-rotation member 320 are both spring sheets. The first anti-rotation member 310 is squeezed between the first side wall 3222a and the first side surface 3100a of the dynamic spring assembly 3100, and is used to provide a first elastic force to the dynamic spring assembly 3100. The second anti-rotation member 320 is squeezed between the second side wall 3222b and the second side surface 3100b of the dynamic spring assembly 3100, and is used to provide a second elastic force to the dynamic spring assembly 3100. The first elastic force is opposite to the second elastic force.

[0166] In the embodiment of the present application, the first anti-rotation component 310 and the second anti-rotation component 320 are both spring sheets. The elastic force provided by the spring sheets can absorb the deflection of the dynamic spring assembly 3100, reduce the deflection force between the dynamic spring assembly 3100 and the first side wall 3222a and the second side wall 3222b of the contact bracket 3220, and reduce the friction resistance and friction noise between the dynamic spring assembly 3100 and the contact bracket 3220.

[0167] like Figure 12 to Figure 14 As shown, the first anti-rotation component 310 and the second anti-rotation component 320 both include a connecting portion 330 and a spring portion 340; the two connecting portions 330 are respectively connected to the first side wall 3222a and the second side wall 3222b, and the two spring portions 340 extend from the two connecting portions 330 in a direction away from the static contact lead-out terminal 2000; the two spring portions 340 are used to provide a first elastic force and a second elastic force to the dynamic spring assembly 3100, respectively.

[0168] The connecting portion 330 includes hooks 331 , and the two hooks 331 are respectively hung on the lower edge of the first opening 3228 and the lower edge of the second opening 3229 .

[0169] like Figures 15 to 17 As shown, the similarities between the moving assembly 3000 of the fourth embodiment of the present application and the moving assembly 3000 of the third embodiment are not repeated here, and the difference lies in that:

[0170] The anti-rotation structure 300 further includes a transition piece 360. One end of the first anti-rotation piece 310 and one end of the second anti-rotation piece 320 are integrally connected to two ends of the transition piece 360 ​​along the third direction D3. The transition piece 360 ​​has a central hole 361. The elastic component 3300 is disposed in the central hole 361.

[0171] In the embodiment of the present application, the anti-rotation structure 300 also has a transition piece 360, which is integrally connected to the first anti-rotation piece 310 and the second anti-rotation piece 320 through the transition piece 360, thereby improving the structural strength of the anti-rotation structure 300 and preventing the first anti-rotation piece 310 and the second anti-rotation piece 320 from shaking.

[0172] like Fig.18 As shown, in another embodiment, both the first anti-rotation component 310 and the second anti-rotation component 320 of the anti-rotation structure 300 are provided with a slot 350. The extending direction of the slot 350 is substantially parallel to the second direction D2.

[0173] like Fig.19 As shown, in another embodiment, both the first anti-rotation component 310 and the second anti-rotation component 320 of the anti-rotation structure 300 are provided with a slot 350. The extending direction of the slot 350 is inclined relative to the second direction D2.

[0174] In the embodiment of the present application, a groove 350 is provided on the first anti-rotation component 310 and the second anti-rotation component 320 to improve the flexibility of the first anti-rotation component 310 and the second anti-rotation component 320. On the one hand, the elastic force of the first anti-rotation component 310 and the second anti-rotation component 320 is reduced so as to better absorb the deflection force of the dynamic spring assembly 3100. On the other hand, the large rigidity of the first anti-rotation component 310 and the second anti-rotation component 320 to avoid wear on the dynamic spring assembly 3100.

[0175] like Figure 20 to Figure 22 As shown, the similarities between the moving assembly 3000 of the fifth embodiment of the present application and the moving assembly 3000 of the fourth embodiment are not repeated here, and the difference lies in that:

[0176] Each connection portion 330 includes a snap-fit ​​structure 332 , and the snap-fit ​​structures 332 of the two connection portions 330 are snap-fitted into the first opening 3228 and the second opening 3229 , respectively.

[0177] like Fig. 22 As shown, the clamping structure 332 includes two connecting pieces 332b, and the connecting pieces 332b are connected to the elastic piece portion 340. A clamping hook 332a is provided on one of the connecting pieces 332b.

[0178] like Fig.23As shown, the clamping structure 332 includes three connecting pieces 332b arranged in sequence along the third direction D3, and there is a gap between two adjacent connecting pieces 332b. Among them, the two outermost connecting pieces 332b are each provided with a clamping hook 332a.

[0179] like Fig.24 As shown, the clamping structure 332 includes a connecting piece 332b, and a clamping hook 332a is provided at one end of the connecting piece 332b along the third direction D3.

[0180] like Figure 25 to Figure 28 As shown, the similarities between the moving assembly 3000 of the sixth embodiment of the present application and the moving assembly 3000 of the fifth embodiment are not repeated here, and the difference lies in that:

[0181] The clamping structure 332 is a sheet-like structure, and the two clamping structures 332 are respectively clamped into the first opening 3228 and the second opening 3229 .

[0182] The first side wall 3222a is further provided with a first connection hole 410, and the second side wall 3222b is further provided with a second connection hole 420. Each connection portion 330 further includes a convex bump 333, and the convex bumps 333 of the two connection portions 330 extend into the first connection hole 410 and the second connection hole 420 respectively, and are respectively interference fit with the first connection hole 410 and the second connection hole 420.

[0183] like Fig. 27 As shown, the cross-sectional shape of the convex hull 333 is circular.

[0184] like Fig.29 As shown, in another embodiment, the cross-section of the convex hull 333 may also be elliptical. Of course, in other embodiments, the cross-section of the convex hull 333 may also be rectangular, triangular or other shapes.

[0185] like Figure 30 to Figure 32 As shown, the similarities between the moving assembly 3000 of the seventh embodiment of the present application and the moving assembly 3000 of the fifth embodiment are not repeated here, and the difference lies in that:

[0186] The first side wall 3222a and the second side wall 3222b are both provided with claws 600. Each connecting portion 330 includes a collar 334, and the collars 334 of the two connecting portions 330 are respectively sleeved on the outer periphery of the claws 600 of the first side wall 3222a and the outer periphery of the claws 600 of the second side wall 3222b.

[0187] In the embodiment of the present application, two protruding claws 600 arranged at intervals along the third direction D3 are provided at one end of the first side wall 3222a away from the base 3211, and the first anti-rotation component 310 is provided with two rings 334. The two rings 334 of the first anti-rotation component 310 are respectively sleeved on the outer periphery of the two protruding claws 600 of the first side wall 3222a.

[0188] The second side wall 3222b has one end away from the base 3211 with two protruding claws 600 spaced apart along the third direction D3. The second anti-rotation component 320 has two rings 334. The two rings 334 of the second anti-rotation component 320 are respectively sleeved on the outer periphery of the two protruding claws 600 of the second side wall 3222b.

[0189] In addition, in the embodiment of the present application, the dynamic spring assembly 3100 includes a dynamic spring sheet 3110 and two second magnetic conductors 6200. The dynamic spring sheet 3110 is provided with a through hole. Each second magnetic conductor 6200 is a U-shaped structure, and two adjacent sides of the two U-shaped structures are inserted into the same through hole.

[0190] like Figure 33 to Figure 35 As shown, the similarities between the moving assembly 3000 of the eighth embodiment of the present application and the moving assembly 3000 of the third embodiment are not repeated here, and the difference lies in that:

[0191] The connection portion 330 of the first anti-rotation member 310 is riveted to the first inner side surface 3223 of the first side wall 3222a facing the dynamic spring assembly 3100 , and the connection portion 330 of the second anti-rotation member 320 is riveted to the second inner side surface 3225 of the second side wall 3222b facing the dynamic spring assembly 3100 .

[0192] In another embodiment, the connection portion 330 of the first anti-rotation component 310 is welded to the first inner side surface 3223 of the first side wall 3222a facing the dynamic spring assembly 3100, and the connection portion 330 of the second anti-rotation component 320 is welded to the second inner side surface 3225 of the second side wall 3222b facing the dynamic spring assembly 3100.

[0193] In addition, in the embodiment of the present application, the anti-rotation structure 300 further includes a transition piece 360 ​​, and one end of the first anti-rotation piece 310 and one end of the second anti-rotation piece 320 are respectively integrally connected to two ends of the transition piece 360 ​​along the third direction D3 .

[0194] like Figure 36 to Figure 38 As shown, the similarities between the moving assembly 3000 of the ninth embodiment of the present application and the moving assembly 3000 of the first embodiment are not repeated here, and the difference lies in that:

[0195] The anti-rotation structure 300 further includes a transition piece 360. One end of the first anti-rotation piece 310 and one end of the second anti-rotation piece 320 are respectively connected to two ends of the transition piece 360 ​​along the third direction D3. The transition piece 360 ​​is fixedly connected to the dynamic spring assembly 3100. One end of the elastic assembly 3300 abuts against the base 3211, and the other end abuts against the transition piece 360.

[0196] As an example, the transition piece 360 ​​is fixedly connected to the second magnetic conductor 6200. Further, the transition piece 360 ​​is connected to the second magnetic conductor 6200 by riveting, welding, etc., but not limited thereto.
