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 around the axis of the push rod, causing the movable spring assembly to rub against the contact bracket of the push rod assembly and generate 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 of the movable spring assembly and the static contact lead-out end, causing 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

[0192] 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.

[0193] like Figure 1 As 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] In one implementation, the relay of the embodiment of the present application is a direct-acting relay.

[0201] 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 .

[0202] 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.

[0203] 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 a surface of the yoke plate 1200 facing the static contact lead-out terminal 2000 . The insulating cover 1100 and the yoke plate 1200 together enclose the contact chamber 1001 .

[0204] 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.

[0205] 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.

[0206] 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.

[0207] 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.

[0208] 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 .

[0209] Please continue reading Figures 3 to 6 The dynamic assembly 3000 includes a dynamic spring assembly 3100, a push rod assembly 3200 and an elastic assembly 3300. The dynamic 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 dynamic 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. The movement direction of the dynamic spring piece 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.

[0210] 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.

[0211] 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.

[0212] It is understandable that the number of the movable reed pieces 3110 can be one or more. When the number of the movable reed pieces 3110 is multiple, the multiple movable reed pieces 3110 are arranged side by side along the third direction, and the number of contacts formed by the multiple movable reed pieces 3110 and each static contact lead-out terminal 2000 is multiple, for example, two, three, four, etc.

[0213] 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.

[0214] 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.

[0215] In other embodiments, the number of the movable reed pieces 3110 may also be one, three, four, five, etc.

[0216] 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 2000. Since the plurality of dynamic spring pieces 3110 will not restrict each other, the two ends of the plurality of dynamic spring pieces 3110 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.

[0217] 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.

[0218] 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.

[0219] Of course, in other embodiments, when the number of the movable spring piece 3110 is one, the number of the second magnet 6200 may also be multiple. For example, at least one opening is provided in the middle of the movable spring piece 3110, and two adjacent second magnets 6200 among the multiple second magnets 6200 are inserted into one opening.

[0220] like Figures 3 to 6 As shown, the push rod assembly 3200 includes a push rod 3210, a contact support 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 support 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 a 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 in 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 arranged on the side of the movable spring assembly 3100 facing the static contact lead-out terminal 2000. The dynamic spring assembly 3100 is installed in the space enclosed by the contact support 3220 and the base 3211 through the elastic assembly 3300 .

[0221] The first side wall 3222a has a first opening 3228, and the second side wall 3222b has a second opening 3229. Both ends of the stop wall 3230 along the width direction of the dynamic spring assembly 3100 are respectively inserted into the first opening 3228 and the second opening 3229.

[0222] 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 .

[0223] 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.

[0224] 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.

[0225] It is understandable that the elastic component 3300 can be used to flexibly support the dynamic spring component 3100 to provide contact pressure.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] like Figures 3 to 6 As 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.

[0230] 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.

[0231] 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.

[0232] 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.

[0233] 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 .

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] 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.

[0242] In a specific implementation, the first magnetic conductor 6100 may be fixedly connected to the ceramic cover 1110 of the contact container 1000 .

[0243] 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.

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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 .

[0248] 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 .

[0249] like Figure 7 and Figure 8 As shown, the relay 1 of the embodiment of the present application further includes an anti-rotation mechanism 300, which is connected to the dynamic spring assembly 3100 and the push rod assembly 3200, and is used to limit the dynamic spring assembly 3100 from rotating relative to the push rod assembly 3200 around the axis of the push rod assembly 3200. In this way, the relay of the embodiment of the present application can avoid the generation of metal noise due to the contact and friction between the dynamic spring assembly 3100 and the push rod assembly 3200 to a certain extent, significantly reduce the risk of metal particles generated by the friction between the dynamic spring assembly 3100 and the push rod assembly 3200, ensure the reliability of the relay product, and further reduce the amplitude of the rotation of the dynamic spring assembly 3100 relative to the push rod assembly 3200 around the axis of the push rod assembly 3200, further ensure the consistency of the contact position between the dynamic spring assembly 3100 and the static contact lead-out terminal 2000, and ensure the stability of the contact resistance.

[0250] In one embodiment, the anti-rotation mechanism 300 includes a first anti-rotation component 100 and a second anti-rotation component 200. The first anti-rotation component 100 is disposed on the first side wall 3222a and the first side surface 3100a, and is used to form a first anti-rotation force between the first side wall 3222a and the first side surface 3100a. The second anti-rotation component 200 is disposed on the second side wall 3222b and the second side surface 3100b, and is used to form a second anti-rotation force between the second side wall 3222b and the second side surface 3100b. The first anti-rotation force and the second anti-rotation force are equal in magnitude and opposite in direction.

[0251] In the relay 1 of the embodiment of the present application, the first anti-rotation component 100 is arranged on the first side wall 3222a and the first side surface 3100a, and is used to form a first anti-rotation force between the first side wall 3222a and the first side surface 3100a. The second anti-rotation component 200 is arranged on the second side wall 3222b and the second side surface 3100b, and is used to form a second anti-rotation force between the second side wall 3222b and the second side surface 3100b. The dynamic spring assembly 3100 is subjected to the anti-rotation force on both sides along the third direction D3, so that the dynamic spring assembly 3100 is maintained between the first side wall 3222a and the second side wall 3222b, thereby preventing the dynamic spring assembly 3100 from rotating relative to the push rod assembly 3200 to a certain extent.

[0252] The first anti-rotation assembly 100 includes a first anti-rotation component 310, and the second anti-rotation assembly 200 includes a second anti-rotation component 320. The first anti-rotation component 310 is disposed between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation component 320 is disposed between the second side wall 3222b and the second side surface 3100b. When the dynamic spring assembly 3100 rotates relative to the axis of the push rod, the first anti-rotation component 310 and / or the second anti-rotation component 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 component 310 and the second anti-rotation component 320.

[0253] like Figure 8 As shown, in the first embodiment of the present application, the first anti-rotation component 310 and the second anti-rotation component 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 component 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 component 320 is attached to the second inner side surface 3225 or the second side surface 3100b. Among them, the reaction force applied by the first anti-rotation component 310 on the first side surface 3100a is the first anti-rotation force; the reaction force applied by the second anti-rotation component 320 on the second side surface 3100b is the second anti-rotation force.

[0254] In one embodiment, the flexible material may be a non-metallic material, such as rubber or wear-resistant plastic, but is not limited thereto.

[0255] 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.

[0256] 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.

[0257] 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.

[0258] 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 member 310 still abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation member 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 member 310 also abuts between the first side wall 3222a and the first side surface 3100a, and the second anti-rotation member 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 rotation of the dynamic spring assembly 3100 relative to the push rod assembly 3200 around the axis of the push rod assembly 3200.

[0259] 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:

[0260] 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 width direction D2 of the movable spring assembly 3100, and the other ends of the two side walls are respectively clamped with the base 3211.

[0261] 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:

[0262] The first anti-rotation component 310 and the second anti-rotation component 320 are both spring sheets. The first anti-rotation component 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 component 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 in opposite directions to the second elastic force. Among them, the first elastic force is the first anti-rotation force, and the second elastic force is the second anti-rotation force.

[0263] 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.

[0264] 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.

[0265] 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 .

[0266] 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:

[0267] The anti-rotation mechanism 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.

[0268] In the embodiment of the present application, the anti-rotation mechanism 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 mechanism 300 and preventing the first anti-rotation piece 310 and the second anti-rotation piece 320 from shaking.

[0269] like Fig.18As shown, in another embodiment, both the first anti-rotation component 310 and the second anti-rotation component 320 are provided with a slot 350. The extending direction of the slot 350 is substantially parallel to the second direction D2.

[0270] like Fig.19 As shown, in another embodiment, both the first anti-rotation component 310 and the second anti-rotation component 320 are provided with a slot 350. The extending direction of the slot 350 is inclined relative to the second direction D2.

[0271] 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.

[0272] 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:

[0273] 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.

[0274] 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.

[0275] like Fig.23 As 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.

[0276] 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.

[0277] 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:

[0278] 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 .

[0279] 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.

[0280] like Fig. 27 As shown, the cross-sectional shape of the convex hull 333 is circular.

[0281] 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.

[0282] 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:

[0283] 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.

[0284] 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.

[0285] 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.

[0286] 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:

[0287] 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 .

[0288] 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.

[0289] In addition, in the embodiment of the present application, the anti-rotation mechanism 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 .

[0290] 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:

[0291] The anti-rotation mechanism 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.

[0292] 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.

[0293] like Figure 39 to Figure 41 As shown, the similarities between the moving assembly 3000 of the tenth embodiment of the present application and the moving assembly 3000 of the ninth embodiment are not repeated here, and the difference lies in that:

[0294] The transition piece 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. In other words, when assembling the push rod assembly 3200, the stop wall 3230, the first magnetic conductor 6100 and the anti-rotation mechanism 300 can be firstly fixedly connected to form an integral part, and then the integral part is connected to the contact bracket 3220.

[0295] Furthermore, the stop wall 3230 , the first magnetic conductor 6100 and the transition piece 360 ​​of the anti-rotation mechanism 300 may be fixedly connected by riveting, welding or the like, but the present invention is not limited thereto.

[0296] like Fig.42 As shown, the similarities between the moving assembly 3000 of the eleventh embodiment of the present application and the moving assembly 3000 of the first embodiment are not repeated here, and the difference lies in that:

[0297] The first anti-rotation component 310 and the second anti-rotation component 320 are both spring pieces. The first anti-rotation component 310 is integrally connected to the first side wall 3222a, and the second anti-rotation component 320 is integrally connected to the second side wall 3222b. The first anti-rotation component 310 is used to provide a first elastic force to the dynamic spring assembly 3100, and the second anti-rotation component 320 is used to provide a second elastic force to the dynamic spring assembly 3100.

[0298] Furthermore, the first side wall 3222a further has a third opening 510, and the second side wall 3222b further has a fourth opening 520. The first anti-rotation component 310 is integrally connected to the upper edge of the third opening 510, and the second anti-rotation component 320 is integrally connected to the upper edge of the fourth opening 520.

[0299] like Fig.43 As shown, the similarities between the moving assembly 3000 of the twelfth embodiment of the present application and the moving assembly 3000 of the eleventh embodiment are not repeated here, and the difference lies in that:

[0300] 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 .

[0301] It should be noted that in the third embodiment to the twelfth embodiment, both the first anti-rotation component 310 and the second anti-rotation component 320 may be provided with a groove 350 .

[0302] like Fig.44 As shown, the similarities between the moving assembly 3000 of the thirteenth embodiment of the present application and the moving assembly 3000 of the first embodiment are not repeated here, and the difference lies in that:

[0303] The first anti-rotation assembly 100 includes a first magnet 110 connected to the first side surface 3100a and a second magnet 120 connected to the first side wall 3222a, and the magnetic poles facing each other of the first magnet 110 and the second magnet 120 are the same magnetic poles, so that a first repulsive force is formed between the first magnet 110 and the second magnet 120. The second anti-rotation assembly 200 includes a third magnet 210 connected to the second side surface 3100b and a fourth magnet 220 connected to the second side wall 3222b, and the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220 are the same magnetic poles, so that a second repulsive force is formed between the third magnet 210 and the fourth magnet 220. The first repulsive force is the first anti-rotation force, and the second repulsive force is the second anti-rotation force.

[0304] In the relay 1 of the embodiment of the present application, the magnetic poles facing each other of the first magnet 110 and the second magnet 120 of the first anti-rotation component 100 are the same magnetic poles, so a repulsive force is generated between the first magnet 110 and the second magnet 120, and the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220 of the second anti-rotation component 200 are the same magnetic poles, so a repulsive force is generated between the third magnet 210 and the fourth magnet 220. Since the first magnet 110 and the third magnet 210 are respectively connected to the first side surface 3100a and the second side surface 3100b of the movable spring assembly 3100, and the second magnet 120 and the fourth magnet 220 are respectively connected to the first side wall 3222a and the second side wall 3222b of the contact bracket 3220, the movable spring assembly 3100 is subjected to a repulsive force on both sides along the third direction D3, and the movable spring assembly 3100 is equivalent to being suspended between the first side wall 3222a and the second side wall 3222b. When the movable spring assembly 3100 moves toward the direction close to the first side wall 3222a, the distance between the first magnet 110 and the second magnet 120 becomes smaller, and the repulsive force increases. The repulsive force can prevent the movable spring assembly 3100 from continuing to move toward the first side wall 3222a, and prevent the movable spring assembly 3100 from contacting the first side wall 3222a and generating metal noise. When the movable spring assembly 3100 moves toward the direction close to the second side wall 3222b, the distance between the third magnet 210 and the fourth magnet 220 becomes smaller, and the repulsive force increases. The repulsive force can prevent the movable spring assembly 3100 from continuing to move toward the second side wall 3222b, and prevent the movable spring assembly 3100 from contacting the second side wall 3222b and generating metal noise.

[0305] It can be seen that in the relay 1 of the embodiment of the present application, the repulsive force generated between the first magnet 110 and the second magnet 120 and the repulsive force generated between the third magnet 210 and the fourth magnet 220, the dynamic spring assembly 3100 is subjected to the repulsive force in the third direction D3, so that the dynamic spring assembly 3100 can be maintained between the first side wall 3222a and the second side wall 3222b without rotating relative to the push rod assembly, thereby avoiding the dynamic spring assembly 3100 from contacting and rubbing with the first side wall 3222a and the second side wall 3222b to generate metal noise; further, the consistency of the contact position between the dynamic spring assembly 3100 and the static contact lead-out terminal 2000 is ensured, and the stability of the contact resistance is ensured. At the same time, since the dynamic spring assembly 3100 will not rotate relative to the push rod assembly, the risk of friction between the dynamic spring assembly 3100 and the contact bracket 3220 to generate metal particles is significantly reduced, thereby ensuring the reliability of the operation of the relay 1 product.

[0306] In one embodiment, the first magnet 110 , the second magnet 120 , the third magnet 210 , and the fourth magnet 220 are all permanent magnets.

[0307] It is understandable that the magnetic poles facing each other of the first magnet 110 and the second magnet 120 can be either N poles or S poles; the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220 can be either N poles or S poles.

[0308] In addition, the magnetic poles facing each other of the first magnet 110 and the second magnet 120 may be the same as or different from the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220. For example, in one embodiment, the magnetic poles facing each other of the first magnet 110 and the second magnet 120 may be N poles, and the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220 may be N poles; in another embodiment, the magnetic poles facing each other of the first magnet 110 and the second magnet 120 may be N poles, and the magnetic poles facing each other of the third magnet 210 and the fourth magnet 220 may be S poles.

[0309] Please continue reading Fig.44 The first side wall 3222a has a first inner side surface 3223 facing the movable spring assembly 3100 and a first outer side surface 3224 disposed opposite to the first inner side surface 3223. The second side wall 3222b has a second inner side surface 3225 facing the movable spring assembly 3100 and a second outer side surface 3226 disposed opposite to the second inner side surface 3225. The second magnet 120 is connected to the first inner side surface 3223, and the fourth magnet 220 is connected to the second inner side surface 3225.

[0310] In one embodiment, the first magnet 110 , the second magnet 120 , the third magnet 210 , and the fourth magnet 220 are all in the shape of a plate, and the first magnet 110 , the second magnet 120 , the third magnet 210 , and the fourth magnet 220 have the same thickness.

[0311] Furthermore, the shapes of the first magnet 110 , the second magnet 120 , the third magnet 210 and the fourth magnet 220 may be rectangular plates or circular plates, but are not limited thereto.

[0312] Optionally, along the third direction D3, the orthographic projections of the first magnet 110, the second magnet 120, the third magnet 210 and the fourth magnet 220 on the first inner side surface 3223 completely overlap, but the present invention is not limited thereto.

[0313] In one embodiment, the first magnet 110 and the third magnet 210 may be connected to the dynamic spring assembly 3100 by bonding, welding, etc. The second magnet 120 and the fourth magnet 220 may be connected to the contact support 3220 by bonding, welding, etc.

[0314] like Fig.45 As shown, the similarities between the moving assembly 3000 of the fourteenth embodiment of the present application and the moving assembly 3000 of the thirteenth embodiment are not repeated here, and the difference lies in that:

[0315] The first magnet 110 is connected to the first side surface 3100 a of the movable spring assembly 3100 , the second magnet 120 is connected to the first outer side surface 3224 , the third magnet 210 is connected to the second side surface 3100 b of the movable spring assembly 3100 , and the fourth magnet 220 is connected to the second outer side surface 3226 .

[0316] like Fig.46 As shown, the similarities between the moving assembly 3000 of the fifteenth embodiment of the present application and the moving assembly 3000 of the thirteenth embodiment are not repeated here, and the difference lies in that:

[0317] The first magnet 110 is connected to the first side surface 3100a of the movable spring assembly 3100 , the second magnet 120 is connected to the first outer side surface 3224 , the third magnet 210 is connected to the second side surface 3100b of the movable spring assembly 3100 , and the fourth magnet 220 is connected to the second inner side surface 3225 .

[0318] like Fig.47 As shown, the similarities between the moving assembly 3000 of the sixteenth embodiment of the present application and the moving assembly 3000 of the thirteenth embodiment are not repeated here, and the difference lies in that:

[0319] The first magnet 110 is connected to the first side surface 3100 a of the movable spring assembly 3100 , the second magnet 120 is connected to the first inner side surface 3223 , the third magnet 210 is connected to the second side surface 3100 b of the movable spring assembly 3100 , and the fourth magnet 220 is connected to the second outer side surface 3226 .

[0320] like Figures 48 to 50 , Fig.62 As shown, the same points as those of the above-mentioned embodiments of the moving assembly 3000 in the seventeenth embodiment of the present application will not be described in detail, and the difference lies in that:

[0321] The anti-rotation mechanism 300 is a limit assembly 1-300, which is connected to the dynamic spring assembly 3100 and the push rod assembly 3200, and is used to limit the dynamic spring assembly 3100 from rotating around the axis of the push rod assembly 3200 relative to the push rod assembly 3200, and the limit assembly 1-300 can be deformed to adapt to overtravel.

[0322] It is understandable that the connection between the limiting assembly 1-300 and the push rod assembly 3200 can be directly connected or indirectly connected. When the limiting assembly 1-300 is indirectly connected to the push rod assembly 3200, the limiting assembly 1-300 can be connected to the push rod assembly 3200 through the elastic assembly 3300, that is, the elastic assembly 3300 is directly connected to the push rod assembly 3200, and the limiting assembly 1-300 is directly connected to the elastic assembly 3300.

[0323] The relay of the embodiment of the present application includes a dynamic spring assembly 3100, a push rod assembly 3200, a limit assembly 1-300 and an elastic assembly 3300. The elastic assembly 3300 can provide contact pressure, and the limit assembly 1-300 can limit the rotation of the dynamic spring assembly 3100 relative to the push rod assembly 3200, thereby ensuring the consistency of the contact positions of the dynamic and static contacts, enhancing the stability of the contact resistance, and improving the reliability of the relay.

[0324] It should be noted that, in the embodiment of the present application, the limit assembly 1-300 can limit the dynamic spring assembly 3100 to rotate about an axis perpendicular to the plane where the dynamic spring assembly 3100 is located. That is, the limit assembly 1-300 can limit the dynamic spring assembly 3100 to rotate around the axis of the push rod assembly 3200 relative to the push rod assembly 3200.

[0325] like Fig.50 and Fig.51 As shown, the elastic component 3300 is a first elastic spring 1-100. As an example, the first elastic spring 1-100 is a sheet structure made of a metal material and is formed by bending.

[0326] The first elastic spring leaf 1 - 100 is installed on the base 3211 of the push rod 3210 through the first anti-rotation structure 1 - 200 , and abuts against a side surface of the movable spring leaf 3110 of the movable spring assembly 3100 facing the push rod 3210 .

[0327] The first elastic spring 1-100 is arranged on the side of the movable spring 3110 facing away from the static contact lead-out terminal 2000, and includes a first base 1-110 and a spring arm 1-120. The first base 1-110 is installed on the push rod 3210 through the first anti-rotation structure 1-200, and at least one spring arm 1-120 is provided at both ends of the first base 1-110 along the first direction D1; the spring arms 1-120 at both ends of the first base 1-110 in the first direction D1 are respectively abutted against the two ends of the movable spring assembly 3100 in the first direction D1.

[0328] In the embodiment of the present application, the spring arms 1-120 at both ends of the first base 1-110 along the first direction D1 are respectively abutted against both ends of the movable spring sheet 3110.

[0329] It can be understood that since the spring arms 1-120 at both ends of the first elastic spring 1-100 are supported on both ends of the movable spring 3110, the movable spring 3110 and the second magnet 6200 can be stably installed on the push rod 3210, avoiding the shaking of the movable spring 3110 and the second magnet 6200, and further avoiding the problem of uneven contact pressure due to the shaking of the movable spring 3110 and the problem of affecting the short-circuit resistance due to the shaking of the second magnet 6200.

[0330] The first elastic spring piece 1-100 and the dynamic spring assembly 3100 together form a receiving cavity 1-500, and the limiting assembly 1-300 is accommodated in the receiving cavity 1-500. By arranging the limiting assembly 1-300 in the receiving cavity 1-500, the structure of the dynamic assembly 3000 can be made more compact, which is conducive to miniaturization of the relay.

[0331] like Fig.49 As shown, at least two spring arms 1-120 arranged side by side along the third direction D3 are provided at both ends of the first direction D1 of the first base 1-110, and the two corresponding spring arms 1-120 of the first elastic spring leaf 1-100 in the first direction D1 are respectively abutted against the two ends of a movable spring leaf 3110 in the first direction D1.

[0332] In the embodiment of the present application, two spring arms 1-120 arranged side by side along the third direction D3 are provided at both ends of the first direction D1 of the first base 1-110. The two spring arms 1-120 at one end of the first direction D1 of the first base 1-110 respectively abut against one end of the two movable spring pieces 3110 arranged side by side, and the two spring arms 1-120 at the other end of the first direction D1 of the first base 1-110 respectively abut against the other end of the two movable spring pieces 3110 arranged side by side.

[0333] It can be seen that in the embodiment of the present application, each movable spring piece 3110 corresponds to a pair of spring arms 1-120, so that when the contact gaps of multiple movable spring pieces 3110 and the static contact lead-out ends are inconsistent, the multiple movable spring pieces 3110 will not interfere with each other.

[0334] like Fig.51 As shown, each spring arm 1-120 includes an extension portion 1-121 and a contact portion 1-122, wherein the extension portion 1-121 is connected to the first base portion 1-110, and the contact portion 1-122 is connected to one end of the extension portion 1-121 away from the first base portion 1-110, and contacts the end of the movable spring piece 3110 in the first direction D1; wherein the width of the end of the extension portion 1-121 connected to the first base portion 1-110 is greater than the width of the end of the extension portion 1-121 connected to the contact portion 1-122. Furthermore, the width of the extension portion 1-121 decreases in a direction from the first base portion 1-110 to the contact portion 1-122.

[0335] In the embodiment of the present application, the first elastic spring 1-100 includes a first base 1-110 and a spring arm 1-120. Since the width of the extension portion 1-121 of the spring arm 1-120 decreases from the first base 1-110 to the abutment portion 1-122, that is, the width of the extension portion 1-121 gradually narrows, the structural strength of the spring arm 1-120 can be reduced to make the spring arm 1-120 softer; in the initial stage of overtravel, after the moving spring 3110 and the static contact lead-out terminal 2000 just come into contact, the spring arm 1-120 will not provide excessive elastic force to avoid mismatch of suction and reaction forces; in addition, precisely because the width of the extension portion 1-121 gradually narrows, the weight of the first elastic spring 1-100 can be slightly reduced; in addition, since the width of the extension portion 1-121 decreases, then in the third direction D3, the spring arm 1-120 can reserve sufficient space for setting other structures.

[0336] Furthermore, the width of the first base 1-110 is greater than the width of the extension 1-121. Since the first base 1-110 is connected to the push rod 3210, and the width of the first base 1-110 is relatively large and greater than the width of the extension 1-121, the structural strength of the first base 1-110 of the first elastic spring 1-100 can be ensured, so that the first elastic spring 1-100 can be firmly connected to the push rod 3210.

[0337] In addition, the root of the extension 1-121 is wide, and the mechanical strength is better, which is conducive to improving the fatigue resistance of the first elastic spring 1-100. The extension 1-121 is set to gradually narrow, so that the stiffness coefficient of the first elastic spring 1-100 changes nonlinearly, reducing the elastic reaction force in the initial stage, and avoiding the mismatch of the suction reaction force at the beginning of the overtravel. In addition, as the first elastic spring 1-100 is gradually compressed, its progress coefficient becomes larger and larger, ensuring that it can provide a sufficiently large contact pressure.

[0338] like Figures 49 to 51 As shown, the first anti-rotation structure 1-200 includes at least two first limiting protrusions 3214 and at least two first limiting holes 1-111. The first limiting protrusion 3214 is provided on one of the first base 1-110 and the push rod assembly 3200, and the first limiting hole 1-111 is provided on the other of the first base 1-110 and the push rod assembly 3200. The at least two first limiting protrusions 3214 are respectively inserted into the at least two first limiting holes 1-111 to achieve an anti-rotation effect.

[0339] In the embodiment of the present application, at least two first limiting protrusions 3214 are protruded from the side surface of the push rod 3210 facing the movable spring assembly 3100; at least two first limiting holes 1-111 are provided on the first base 1-110.

[0340] In the embodiment of the present application, the first anti-rotation structure 1-200 includes two first limiting protrusions 3214 and two first limiting holes 1-111. The two first limiting protrusions 3214 are convexly arranged on a side surface of the base 3211 facing the dynamic spring assembly 3100, and the two first limiting protrusions 3214 are arranged side by side along the third direction D3 and are respectively inserted into the two first limiting holes 1-111.

[0341] It should be noted that, since the first anti-rotation structure 1-200 of the embodiment of the present application includes at least two first limiting protrusions 3214 and first limiting holes 1-111 that cooperate with each other, the shape of the first limiting hole 1-111 can be circular.

[0342] Of course, in other embodiments, the first anti-rotation structure 1-200 may also include a first limiting protrusion 3214 and a first limiting hole 1-111, and the shape of the first limiting hole 1-111 is a non-circular shape such as a rectangle, an ellipse, or a triangle. The first limiting protrusion 3214 is adapted to the shape of the first limiting hole 1-111, and is inserted into the first limiting hole 1-111, which can prevent the push rod 3210 and the first elastic spring 1-100 from rotating relative to each other.

[0343] It can be understood that the first anti-rotation structure 1-200 is used to limit the rotation of the first elastic spring 1-100 around the axis of the push rod assembly 3200 relative to the push rod assembly 3200.

[0344] It can be understood that, in other embodiments, the first anti-rotation structure 1-200 may also include a riveted structure, a welded structure, an adhesive structure, etc. When the first anti-rotation structure 1-200 is a riveted structure, the first base 1-110 is riveted to the push rod assembly 3200; when the first anti-rotation structure 1-200 is a welded structure, the first base 1-110 is welded to the push rod assembly 3200; when the first anti-rotation structure 1-200 is an adhesive structure, the first base 1-110 is adhesively bonded to the push rod assembly 3200.

[0345] In another embodiment, the first anti-rotation structure 1-200 may further include a fastener, which fastens the first elastic spring 1-100 and the push rod assembly 3200.

[0346] like Fig.49 , Fig.50 and Fig.52As shown, the limiting component 1-300 is a second elastic spring 1-300a, which can be a sheet structure made of metal material and formed by bending. The second elastic spring 1-300a is connected to one of the elastic component 3300 and the dynamic spring component 3100 through the second anti-rotation structure 1-400, and is connected to the other of the elastic component 3300 and the dynamic spring component 3100 through the third anti-rotation structure 1-700.

[0347] In an embodiment of the present application, the second elastic spring 1-300a is connected to the first base 1-110 through the second anti-rotation structure 1-400, and is connected to the dynamic spring assembly 3100 through the third anti-rotation structure 1-700.

[0348] like Figure 52 to Figure 54 As shown, the second anti-rotation structure 1-400 includes at least two second limiting protrusions 1-410 and at least two second limiting holes 1-311. The second limiting protrusion 1-410 is provided on one of the first elastic spring 1-100 and the second elastic spring 1-300a, and the second limiting hole 1-311 is provided on the other of the first elastic spring 1-100 and the second elastic spring 1-300a.

[0349] In the embodiment of the present application, each second limiting protrusion 1-410 is a convex ring 1-112. At least two convex rings 1-112 are arranged on a side surface of the first base 1-110 facing the movable spring assembly 3100, and one convex ring 1-112 surrounds a first limiting hole 1-111; the inner ring surface 1-112b of the convex ring 1-112 is flush with the hole wall of the first limiting hole 1-111; at least two second limiting holes 1-311 are arranged on the second elastic spring sheet 1-300a; wherein, at least two convex rings 1-112 are respectively inserted into at least two second limiting holes 1-311.

[0350] In the embodiment of the present application, the second anti-rotation structure 1-400 includes two protruding rings 1-112 and two second limiting holes 1-311.

[0351] It should be noted that, since the second anti-rotation structure 1-400 of the embodiment of the present application includes at least two mutually cooperating convex rings 1-112 and a second limiting hole 1-311, the shape of the second limiting hole 1-311 can be circular.

[0352] Of course, in other embodiments, the second anti-rotation structure 1-400 may also include a convex ring 1-112 and a second limiting hole 1-311, and the shape of the second limiting hole 1-311 is a non-circular shape such as a rectangle, an ellipse, or a triangle. The convex ring 1-112 is inserted into the second limiting hole 1-311 to prevent the second elastic spring 1-300a and the first elastic spring 1-100 from rotating relative to each other.

[0353] It can be understood that the second anti-rotation structure 1-400 is used to limit the rotation of the second elastic reed 1-300a around the axis of the push rod assembly 3200 relative to the first elastic reed 1-100.

[0354] In one embodiment, the convex ring 1-112 is formed by folding the edge of the first limiting hole 1-111 of the first base 1-110 toward the direction close to the dynamic spring assembly 3100. In the embodiment of the present application, by setting the convex ring 1-112 on the edge of the first limiting hole 1-111, the friction between the first limiting protrusion 3214 and the first base 1-110 can be reduced when the first base 1-110 and the push rod 3210 are assembled, and the generation of scraps can be prevented. At the same time, the convex ring 1-112 cooperates with the second limiting hole 1-311 of the second elastic spring 1-300a, and can also prevent the second elastic spring 1-300a from rotating relative to the first elastic spring 1-100. In addition, the folded convex ring 1-112 can increase the contact area between the first limiting protrusion 3214 and the first base 1-110, and reduce the wear between the first limiting protrusion 3214 and the first base 1-110 during movement.

[0355] like Fig.54 As shown, the convex ring 1-112 is provided with a top surface 1-112a facing away from the first base 1-110, and a chamfer 1-113 is provided at the connection between the top surface 1-112a and the inner ring surface 1-112b. By providing the chamfer 1-113 at the connection between the top surface 1-112a and the inner ring surface 1-112b, burrs generated during the molding process of the convex ring 1-112 can be eliminated, and scraping can be further prevented from being generated between the first limiting protrusion 3214 and the inner ring surface 1-112b of the convex ring 1-112.

[0356] It can be understood that, in other embodiments, the second anti-rotation structure 1-400 may also include a riveted structure, a welded structure, an adhesive structure, etc. When the second anti-rotation structure 1-400 is a riveted structure, the first elastic spring 1-100 and the second elastic spring 1-300a are riveted; when the second anti-rotation structure 1-400 is a welded structure, the first elastic spring 1-100 and the second elastic spring 1-300a are welded; when the second anti-rotation structure 1-400 is an adhesive structure, the first elastic spring 1-100 and the second elastic spring 1-300a are adhesively bonded.

[0357] In another embodiment, the second anti-rotation structure 1-400 may further include a fastener, which fastens the first elastic spring 1-100 and the second elastic spring 1-300a.

[0358] Please return to Fig.50 and Fig.52As shown, the second elastic spring 1-300a is arranged on the side of the movable spring assembly 3100 facing away from the static contact lead-out end 2000. The second elastic spring 1-300a includes a second base 1-310, a first deformation portion 1-320 and a first connecting portion 1-330. The second base 1-310 is installed on one of the first elastic spring 1-100 and the movable spring assembly 3100 through a second anti-rotation structure 1-400. The second base 1-310 is provided with a first deformation portion 1-320 and a first connecting portion 1-330 on both sides along the first direction D1, and the second base 1-310 is connected to the first connecting portion 1-330 through the first deformation portion 1-320; the first connecting portion 1-330 is connected to the other of the first elastic spring 1-100 and the movable spring assembly 3100 through a third anti-rotation structure 1-700.

[0359] In the embodiment of the present application, the first connection portion 1-330 of the second elastic spring piece 1-300a is connected to the dynamic spring assembly 3100 through the third anti-rotation structure 1-700, and the second base 1-310 is installed on the first base 1-110 of the first elastic spring piece 1-100 through the second anti-rotation structure 1-400, so that the second elastic spring piece 1-300a can position the dynamic spring assembly 3100 in the second direction D2, and limit the dynamic spring assembly 3100 in the first direction D1 and the third direction D3, so that the second elastic spring piece 1-300a can limit the dynamic spring assembly 3100, avoid the dynamic spring assembly 3100 from rotating relative to the push rod 3210, and thus avoid the dynamic and static contacts from being unable to align and affecting the reliability of the relay. In addition, the dynamic spring assembly 3100 is limited by the second elastic spring piece 1-300a, avoiding the ripple sound generated by the contact between the dynamic spring assembly 3100 and the contact bracket when the dynamic spring assembly 3100 is energized.

[0360] In addition, since the dynamic spring assembly 3100 does not rotate, it can reduce or even prevent the dynamic spring assembly 3100 from contacting the side wall of the contact bracket 3220 to a certain extent, thereby avoiding the generation of large corrugation sound (metal friction noise). In addition, it avoids the increase in the number of frictions and the aggravation of the wear, which leads to an increase in the deflection force and friction resistance. Furthermore, it can also reduce the metal particles generated by the mutual friction between the dynamic spring assembly 3100 and the contact bracket 3220, reduce the probability of metal particles falling on the contact surface of the contact point, and thus reduce the quality risk of increasing the contact resistance or even non-conduction.

[0361] In which, during the over-travel process, the push rod 3210 continues to move toward the dynamic spring assembly 3100. At this time, the first deformation part 1-320 is compressed and deformed, which does not affect the over-travel.

[0362] In addition, since the first elastic reed 1-100 is used to provide contact pressure, and the second elastic reed 1-300a does not need to provide contact pressure, the thickness of the second elastic reed 1-300a can be smaller than the thickness of the first elastic reed 1-100, thereby reducing the stress at the bending point of the second elastic reed 1-300a and avoiding fatigue fracture of the second elastic reed 1-300a.

[0363] In the embodiment of the present application, along the first direction D1, two first deformation parts 1-320 and two first connection parts 1-330 are provided on both sides of the second base 1-310. One side of the second base 1-310 is connected to the two first connection parts 1-330 through the two first deformation parts 1-320. The two first deformation parts 1-320 located on one side of the second base 1-310 are arranged side by side along the third direction D3. The two first connection parts 1-330 located on one side of the second base 1-310 are respectively connected to the two second magnetic conductors 6200.

[0364] It can be seen that in the embodiment of the present application, each movable spring piece 3110 corresponds to a pair of first connecting parts 1-330, so that when the contact gaps of multiple movable spring pieces 3110 and the static contact lead-out ends are inconsistent, the multiple movable spring pieces 3110 will not interfere with each other.

[0365] like Fig.50 As shown, along the first direction D1, the first connection portion 1-330 on one side of the second base 1-310 forms a first connection 1-700a with the dynamic spring assembly 3100, and the first connection portion 1-330 on the other side of the second base 1-310 forms a second connection 1-700b with the dynamic spring assembly 3100. There is a first distance L1 between the first connection 1-700a and the second connection 1-700b, and there is a second distance L2 between the first deformation portions 1-320 on both sides of the second base 1-310, and the first distance L1 is smaller than the second distance L2. Among them, the second distance L2 is the maximum distance between the first deformation portions 1-320 on both sides of the second base 1-310.

[0366] In the embodiment of the present application, since the first distance L1 is smaller than the second distance L2, during the overtravel process, the second elastic spring 1-300a is compressed by the push rod 3210 and the dynamic spring assembly 3100, so that the first deformation portions 1-320 on both sides of the second base 1-310 can be deformed in a direction away from each other (the first deformation portions 1-320 on both sides expand outward), thereby preventing the second elastic spring 1-300a from getting stuck and being unable to provide contact pressure. In addition, since the first distance L1 is smaller than the second distance L2, the first deformation portions 1-320 on both sides of the second base 1-310 are equivalent to being bent in a direction close to each other as a whole, which can reduce the overall volume of the second elastic spring 1-300a and reduce the space occupancy rate.

[0367] Of course, in other embodiments, when the internal space of the relay is large enough, the first distance L1 may also be greater than the second distance L2.

[0368] like Fig.50 and Fig.52 As shown, the third anti-rotation structure 1-700 includes at least two third limiting protrusions 1-710 and at least two third limiting holes 1-720, the at least two third limiting protrusions 1-710 are provided on one of the second elastic spring piece 1-300a and the dynamic spring assembly 3100, and the at least two third limiting holes 1-720 are provided on the other of the second elastic spring piece 1-300a and the dynamic spring assembly 3100. The at least two third limiting protrusions 1-710 are respectively inserted into the at least two third limiting holes 1-720.

[0369] In the embodiment of the present application, the number of the third limiting holes 1-720 is four, and the number of the third limiting protrusions 1-710 is four. The four third limiting holes 1-720 are respectively provided on the four first connecting parts 1-330, and the four third limiting protrusions 1-710 are provided on the two second magnetic conductors 6200, and each second magnetic conductor 6200 is provided with two third limiting protrusions 1-710.

[0370] It can be understood that, in other embodiments, the third anti-rotation structure 1-700 may also include a riveted structure, a welded structure, an adhesive structure, etc. When the third anti-rotation structure 1-700 is a riveted structure, the second base 1-310 is riveted to the first elastic spring 1-100 or the dynamic spring assembly 3100; when the third anti-rotation structure 1-700 is a welded structure, the second base 1-310 is welded to the first elastic spring 1-100 or the dynamic spring assembly 3100; when the third anti-rotation structure 1-700 is an adhesive structure, the second base 1-310 is adhesively bonded to the first elastic spring 1-100 or the dynamic spring assembly 3100.

[0371] In another embodiment, the third anti-rotation structure 1-700 may further include a fastener, which fastens the first elastic spring 1-100 and one of the dynamic spring assembly 3100 to the second elastic spring 1-300a.

[0372] In one embodiment, the elastic component 3300 is connected to the push rod component 3200 in a limited position along the first direction D1; and / or, the limit component 1-300 is connected to the dynamic spring component 3100 in a limited position along the first direction D1; and / or, the limit component 1-300 is connected to the elastic component 3300 in a limited position along the first direction D1. In this way, the amplitude of the dynamic spring component 3100 moving relative to the push rod component 3200 in the first direction D1 can be reduced, thereby improving the overall impact resistance of the relay.

[0373] Preferably, the elastic component 3300 is connected to the push rod component 3200 in a limited position along the first direction D1, and the limit component 1-300 is connected to the dynamic spring component 3100 in a limited position along the first direction D1, and the limit component 1-300 is connected to the elastic component 3300 in a limited position along the first direction D1. In this way, when the relay encounters a large impact, the moving contact and the static contact will not shift, avoiding unstable contact resistance.

[0374] In another embodiment, the shape of the third limiting hole 1-720 is an ellipse, and the major axis of the ellipse is parallel to the first direction D1. By designing the third limiting hole 1-720 to be an ellipse, before the moving and static contacts come into contact, the third limiting protrusion 1-710 is limited to the outer edge of the third limiting hole 1-720, so that the dynamic spring assembly 3100 will not move. After the moving and static contacts come into contact, the second elastic spring 1-300a is compressed, and the first connecting portion and the first deformation portion on both sides of the second base 1-310 have a tendency to move to both sides. At this time, the elliptical third limiting hole 1-720 can provide space for the first connecting portion 1-330 to move, so as to release the stress generated inside the second elastic spring 1-300a after being compressed, and prevent the internal stress of the second elastic spring 1-300a from being too concentrated and affecting its service life.

[0375] In addition, it is worth mentioning that since the distance that the first connecting portion 1-330 moves within the ellipse is small, it does not affect the relative position of the moving contact and the static contact.

[0376] It can be understood that the first anti-rotation structure 1-200, the second anti-rotation structure 1-400 and the third anti-rotation structure 1-700 can be the same or different.

[0377] like Fig.55 and Fig.56 As shown, the similarities between the dynamic assembly of the eighteenth embodiment of the present application and the dynamic assembly of the seventeenth embodiment are not repeated here, and the difference is that the second elastic spring 1-300a includes a second base 1-310, a first deformation portion 1-320 and a first connecting portion 1-330. The second base 1-310 is connected to the dynamic spring assembly 3100 through a second anti-rotation structure 1-400. The first deformation portion 1-320 and the first connecting portion 1-330 are provided on both sides of the first direction D1 of the second base 1-310, and the second base 1-310 is connected to the first connecting portion 1-330 through the first deformation portion 1-320, and the first connecting portion 1-330 is connected to the first base 1-110 of the first elastic spring 1-100 through a third anti-rotation structure 1-700.

[0378] In the embodiment of the present application, the second base 1-310 is connected to the second magnetic conductor 6200 through the second anti-rotation structure 1-400. The second limiting hole 1-311 of the second anti-rotation structure 1-400 is provided on the second base 1-310, and the second limiting protrusion 1-410 is provided on the second magnetic conductor 6200. The third limiting hole 1-720 of the third anti-rotation structure 1-700 is provided on the first connecting portion 1-330, and the third limiting protrusion 1-710 is provided on the first base 1-110.

[0379] like Fig.57 and Fig.58 As shown, the similarities between the moving assembly of the nineteenth embodiment of the present application and the moving assembly of the seventeenth embodiment are not repeated here, and the difference is that the second base 1-310 of the second elastic spring 1-300a is connected to the first base 1-110 of the first elastic spring 1-100 through the second anti-rotation structure 1-400. The first connecting parts 1-330 on both sides of the second base 1-310 are respectively inserted between the second magnetic conductor 6200 and the moving spring 3110 by the second magnetic conductor 6200 along the first direction D1, and are fixedly connected to the moving spring 3110 and the second magnetic conductor 6200.

[0380] like Fig.59 As shown, the similarities between the moving assembly of the twentieth embodiment of the present application and the moving assembly of the seventeenth embodiment are not repeated here, and the difference is that the moving spring assembly 3100 includes a moving spring sheet 3110 and a second magnetic conductor 6200. A spring arm 1-120 is provided on both sides of the first base 1-110, and a first deformation portion 1-320 and a first connecting portion 1-330 are provided on both sides of the second base 1-310.

[0381] like Fig.60 As shown, the similarities between the moving assembly of the twenty-first embodiment of the present application and the moving assembly of the seventeenth embodiment are not repeated here, and the difference lies in that:

[0382] The movable spring assembly 3100 includes three movable spring pieces 3110 and three second magnetic conductors 6200 arranged side by side. Three spring arms 1-120 are provided on both sides of the first base 1-110, and three first deformation parts 1-320 and three first connecting parts 1-330 are provided on both sides of the second base 1-310. The three spring arms 1-120 on one side of the first base 1-110 are respectively abutted against one end of the three movable spring pieces 3110, and the three spring arms 1-120 on the other side of the first base 1-110 are respectively abutted against the other ends of the three movable spring pieces 3110. The six first connecting parts 1-330 on both sides of the second base 1-310 are divided into three pairs, and the two first connecting parts 1-330 of each pair are arranged opposite to each other in the first direction D1, and the three pairs of first connecting parts 1-330 are respectively connected to the three second magnetic conductors 6200 in a one-to-one correspondence.

[0383] like Fig.61 As shown, the similarities between the moving assembly of the twenty-second embodiment of the present application and the moving assembly of the seventeenth embodiment are not repeated here, and the difference lies in that:

[0384] The elastic component 3300 is a compression spring 1-600, which is disposed in a chamber 1-800 surrounded by the second elastic spring 1-300a and the second magnetic conductor 6200, and one end of the compression spring 1-600 abuts against the second magnetic conductor 6200, and the other end of the compression spring 1-600 abuts against the second base 1-310 of the second elastic spring 1-300a. The compression spring 1-600 is used to provide contact pressure.

[0385] Of course, in other embodiments, the second base 1-310 of the second elastic spring 1-300a can also be connected to the second magnetic conductor 6200 of the movable spring assembly 3100, and the first connecting portion 1-330 of the second elastic spring 1-300a is connected to the push rod assembly 3200. The compression spring 1-600 is accommodated in a chamber surrounded by the second elastic spring 1-300a and the push rod assembly 3200. One end of the compression spring 1-600 abuts against the push rod assembly 3200, and the other end of the compression spring 1-600 abuts against the second base 1-310 of the second elastic spring 1-300a. In other embodiments, the limit assembly 1-300 is not limited to the second elastic spring 1-300a with a spring structure. For example, the limit assembly 1-300 may also include a telescopic rod, one end of which is connected to the dynamic spring assembly 3100, and the other end of the telescopic rod is connected to the first elastic spring 1-100 or the push rod assembly 3200, and the telescopic rod can be extended and retracted along the second direction D2; in another embodiment, the limit assembly 1-300 may also include at least two compression springs, one end of each compression spring is limitedly connected or fixedly connected to the first elastic spring 1-100, and the other end of each compression spring is limitedly connected or fixedly connected to the dynamic spring assembly 3100.

[0386] like Fig.63 and Fig.64 As shown, the similarities between the moving assembly of the twenty-third embodiment of the present application and the moving assembly of the seventeenth embodiment are not repeated here, and the difference lies in that:

[0387] The anti-rotation mechanism 300 is an elastic component 3300, which is connected to the push rod component 3200 through the first anti-rotation structure 1-200 and connected to the dynamic spring component 3100 through the second anti-rotation structure 1-400. The elastic component 3300 is used to provide contact pressure and to limit the dynamic spring component 3100 from rotating around the axis of the push rod component 3200 relative to the push rod component 3200.

[0388] The elastic component 3300 is a third elastic spring 2-100. As an example, the third elastic spring 2-100 is a sheet structure made of a metal material and is formed by bending.

[0389] The third elastic spring 2-100 includes a third base 2-110, a second connecting portion 2-120 and a second deforming portion 130. The third base 2-110 is connected to the push rod assembly 3200 through the first anti-rotation structure 1-200. The second connecting portion 2-120 and the second deforming portion 130 are provided on both sides of the third base 2-110 along the first direction D1, and the third base 2-110 is connected to the second connecting portion 2-120 through the second deforming portion 130. The second connecting portion 2-120 of the third elastic spring 2-100 is connected to the dynamic spring assembly 3100 through the second anti-rotation structure 1-400. Among them, the second deforming portion 130 is used to generate deformation to provide contact pressure.

[0390] like Fig.65 As shown, the third elastic spring 2-100 is arranged on the side of the movable spring 3110 facing away from the static contact lead-out end 2000, and two second connecting parts 2-120 and two second deformation parts 130 are provided on each side of the first direction D1 of the third base 2-110, and the third base 2-110 is connected to the two second connecting parts 2-120 through the two second deformation parts 130 on each side along the first direction D1.

[0391] In an embodiment of the present application, the third elastic spring 2-100 includes a third base 2-110, a second connecting portion 2-120 and a second deformation portion 130. The third base 2-110 is connected to the push rod assembly 3200 via a first anti-rotation structure 1-200, and the second connecting portion 2-120 is connected to the movable spring assembly 3100 via a second anti-rotation structure 1-400. The second deformation portion 130 can be deformed to provide contact pressure. The movable spring assembly 3100 is connected to the push rod assembly 3200 via the third elastic spring 2-100, thereby avoiding rotation of the movable spring assembly 3100 relative to the push rod assembly 3200, thereby ensuring the consistency of the contact position between the movable spring assembly 3100 and the static contact lead-out terminal 2000, thereby improving the reliability of the relay.

[0392] In addition, since the dynamic spring assembly 3100 does not rotate, it can reduce or even prevent the dynamic spring assembly 3100 from contacting the side wall of the contact bracket 3220 to a certain extent, thereby avoiding the generation of large corrugation sound (metal friction noise). In addition, it avoids the increase in the number of frictions and the aggravation of the wear, which leads to an increase in the deflection force and friction resistance. Furthermore, it can also reduce the metal particles generated by the mutual friction between the dynamic spring assembly 3100 and the contact bracket 3220, reduce the probability of metal particles falling on the contact surface of the contact point, and thus reduce the quality risk of increasing the contact resistance or even non-conduction.

[0393] It should be noted that the first anti-rotation structure 1-200 is used to limit the relative rotation between the third elastic spring 2-100 and the pushing rod assembly 3200 around the axis of the pushing rod assembly 3200, and the second anti-rotation structure 1-400 is used to limit the relative rotation between the third elastic spring 2-100 and the dynamic spring assembly 3100 around the axis of the pushing rod assembly 3200, so that the third elastic spring 2-100 can limit the rotation of the dynamic spring assembly 3100 relative to the pushing rod assembly 3200 around the axis of the pushing rod assembly 3200.

[0394] In other embodiments, the third base 2-110 is connected to the push rod 3210 via the second anti-rotation structure 1-400, and the second connecting portion 2-120 is connected to the dynamic spring assembly 3100 via the first anti-rotation structure 1-200.

[0395] like Fig.64 As shown, the third elastic spring piece 2-100 and the movable spring piece 3110 together form a receiving cavity 2-200 for accommodating the second magnetizer 6200. The receiving cavity 2-200 can avoid the second magnetizer 6200 and prevent the third elastic spring piece 2-100 from interfering with the second magnetizer 6200 during the overtravel process.

[0396] like Fig.64 and Fig.73 As shown, along the first direction D1, the second connection part 2-120 on one side of the third base 2-110 forms a third connection 400a with the dynamic spring assembly 3100, and the second connection part 2-120 on the other side of the third base 2-110 forms a fourth connection 400b with the dynamic spring assembly 3100, and there is a third distance L3 between the third connection 400a and the fourth connection 400b, and there is a fourth distance L4 between the second deformation parts 130 on both sides of the third base 2-110, and the third distance L3 is smaller than the fourth distance L4. Among them, the fourth distance L4 is the maximum distance between the second deformation parts 130 on both sides of the third base 2-110.

[0397] In the embodiment of the present application, since the third distance L3 is smaller than the fourth distance L4, during the overtravel process, the third elastic spring 2-100 is compressed by the push rod 3210 and the dynamic spring assembly 3100, so that the second deformation portions 130 on both sides of the third base 2-110 can be deformed in a direction away from each other (the second deformation portions 130 on both sides expand outward), thereby preventing the third elastic spring 2-100 from getting stuck and unable to provide contact pressure. In addition, since the third distance L3 is smaller than the fourth distance L4, the second deformation portions 130 on both sides of the third base 2-110 are equivalent to being bent in a direction close to each other as a whole, which can reduce the overall volume of the third elastic spring 2-100 and reduce the space occupancy rate.

[0398] Of course, in other embodiments, when the internal space of the relay is large enough, the third distance L3 may also be greater than the fourth distance L4.

[0399] The second deformation parts 130 on both sides of the third base 2-110 are bent from both sides of the third base 2-110 first in the direction away from each other, and then bent in the direction close to the dynamic spring assembly 3100 and close to each other.

[0400] like Fig.64 As shown, the second connecting parts 2-120 on both sides of the third base 2-110 of the third elastic spring 2-100 are respectively connected to the two ends of the first direction D1 of the movable spring 3110, so that the movable spring assembly 3100 can be more stably connected to the third elastic spring 2-100, further avoiding the shaking of the movable spring assembly 3100 and affecting the consistency of the contact.

[0401] like Figure 64 to Figure 66 As shown, the dynamic spring assembly 3100 includes at least two dynamic spring pieces 3110 and at least two second magnetic conductors 6200 arranged side by side, and the at least two second magnetic conductors 6200 are respectively fixedly connected to the at least two dynamic spring pieces 3110. Each side of the third base 2-110 of the third elastic spring piece 2-100 is provided with at least two second deformation parts 130 and at least two second connecting parts 2-120. The third base 2-110 is connected to the push rod 3210 through the first anti-rotation structure 1-200, and one side of the third base 2-110 is respectively connected to the at least two second connecting parts 2-120 through the at least two second deformation parts 130. At least four second connecting parts 2-120 are connected to the at least two dynamic spring pieces 3110 of the dynamic spring assembly 3100 through the second anti-rotation structure 1-400.

[0402] In the embodiment of the present application, the dynamic spring assembly 3100 includes two dynamic spring pieces 3110 and two second magnetic conductors 6200, and each side of the third base 2-110 is provided with two second deformation parts 130 and two second connection parts 2-120. The four second connection parts 2-120 are divided into two pairs, and each pair of second connection parts 2-120 is arranged opposite to each other in the first direction D1 of the dynamic spring piece 3110. The two pairs of second connection parts 2-120 are connected to the two dynamic spring pieces 3110 through the second anti-rotation structure 1-400.

[0403] It can be seen that in the embodiment of the present application, each movable spring piece 3110 corresponds to a pair of second connecting parts 2-120, so that when the contact gaps of multiple movable spring pieces 3110 and the static contact lead-out ends are inconsistent, the multiple movable spring pieces 3110 will not interfere with each other.

[0404] like Fig.64 and Fig.65As shown, each second deformation portion 130 includes a first section 131, a second section 132 and a third section 133. One end of the first section 131 is connected to the third base 2-110; one end of the second section 132 is connected to the other end of the first section 131; the second section 132 is bent from the first section 131 in a direction away from the dynamic spring assembly 3100, and the second sections 132 on both sides of the third base 2-110 are tilted relative to the axis of the push rod assembly 3200 in a direction away from each other; one end of the third section 133 is connected to the other end of the second section 132; the third section 133 is bent from the second section 132 in a direction close to the dynamic spring assembly 3100, and the third sections 133 on both sides of the third base 2-110 are tilted relative to the axis of the push rod assembly 3200 in a direction close to each other; wherein the other end of the third section 133 is connected to the second connecting portion 2-120, and the second connecting portions 2-120 on both sides of the third base 2-110 extend from the third section 133 in a direction close to each other.

[0405] Furthermore, a first bending connection 136 is formed between the first section 131 and the second section 132 of each second deformation portion 130 ; along the second direction D2 , the second connection portion 2 - 120 corresponds to the position of the first bending connection 136 .

[0406] like Fig.65 , Fig.67 and Fig.68 As shown, in one embodiment, the third base 2-110 can be a sheet structure. The first anti-rotation structure 1-200 includes at least two first limiting holes 1-111 and at least two first limiting protrusions 3214. At least two first limiting holes 1-111 are provided on one of the elastic component 3300 and the push rod component 3200, and at least two first limiting protrusions 3214 are provided on the other of the elastic component 3300 and the push rod component 3200.

[0407] In the embodiment of the present application, at least two first limiting holes 1-111 are provided in the third base portion 2-110, and the first limiting holes 1-111 can penetrate the two side surfaces of the third base portion 2-110 in the thickness direction, and at least two first limiting protrusions 3214 are provided on the side surface of the push rod 3210 facing the dynamic spring assembly 3100. The at least two first limiting protrusions 3214 are inserted into the at least two first limiting holes 1-111.

[0408] In the embodiment of the present application, at least two first limiting protrusions 3214 are provided on the side of the base 3211 of the push rod 3210 facing the static contact lead-out terminal 2000, and the at least two first limiting protrusions 3214 are arranged side by side along the third direction D3.

[0409] It should be noted that, since the first anti-rotation structure 1-200 of the embodiment of the present application includes at least two first limiting protrusions 3214 and first limiting holes 1-111 that cooperate with each other, the shape of the first limiting hole 1-111 can be circular.

[0410] Of course, in other embodiments, the first anti-rotation structure 1-200 may also include a first limiting protrusion 3214 and a first limiting hole 1-111, and the shape of the first limiting hole 1-111 is a non-circular shape such as a rectangle, an ellipse, or a triangle. The first limiting protrusion 3214 is adapted to the shape of the first limiting hole 1-111, and is inserted into the first limiting hole 1-111, which can prevent the push rod 3210 and the third elastic spring 2-100 from rotating relative to each other.

[0411] It can be understood that the first anti-rotation structure 1-200 can prevent the third elastic spring 2-100 from rotating with an axis perpendicular to the plane where the movable spring 3110 is located as the rotation axis.

[0412] It can be understood that, in other embodiments, the first anti-rotation structure 1-200 may also include a riveted structure, a welded structure, an adhesive structure, etc. When the first anti-rotation structure 1-200 is a riveted structure, the third base 2-110 is riveted to the push rod assembly 3200; when the first anti-rotation structure 1-200 is a welded structure, the third base 2-110 is welded to the push rod assembly 3200; when the first anti-rotation structure 1-200 is an adhesive structure, the third base 2-110 is adhesively bonded to the push rod assembly 3200.

[0413] In another embodiment, the first anti-rotation structure 1-200 may further include a fastener, which fastens the third elastic spring 2-100 and the push rod assembly 3200.

[0414] like Fig.68 As shown, a convex ring 1-112 surrounding the first limiting hole 1-111 is provided on the side of the third base 2-110 facing the movable spring 3110, and the inner ring surface 1-112b of the convex ring 1-112 is flush with the hole wall of the first limiting hole 1-111. Further, the convex ring 1-112 is formed by folding the hole edge of the first limiting hole 1-111 of the third base 2-110 toward the direction close to the movable spring 3110. By providing the convex ring 1-112 on the edge of the first limiting hole 1-111, the friction between the first limiting protrusion 3214 and the third base 2-110 can be reduced when the third base 2-110 is assembled with the push rod 3210, and the generation of scraps can be prevented. In addition, the convex ring 1-112 formed by the folding can increase the contact area between the first limiting protrusion 3214 and the third base 2-110, thereby reducing the wear between the first limiting protrusion 3214 and the third base 2-110 during movement.

[0415] The convex ring 1-112 is provided with a top surface 1-112a facing away from the third base 2-110, and a chamfer 1-113 is provided at the connection between the top surface 1-112a and the inner ring surface 1-112b. By providing the chamfer 1-113 at the connection between the top surface 1-112a and the inner ring surface 1-112b, burrs generated during the molding process of the convex ring 1-112 can be eliminated, and scrapings can be further prevented from being generated between the first limiting protrusion 3214 and the inner ring surface 1-112b of the convex ring 1-112.

[0416] like Fig.64 and Fig.65 As shown, the second anti-rotation structure 1-400 includes at least two second limiting holes 1-311 and at least two second limiting protrusions 1-400, at least two second limiting holes 1-311 are arranged on one of the elastic component 3300 and the dynamic spring component 3100, and at least two second limiting protrusions 1-400 are arranged on the other of the elastic component 3300 and the dynamic spring component 3100.

[0417] In the embodiment of the present application, the number of the second limiting holes 1-311 is four, and the number of the second limiting protrusions 1-400 is four. The four second limiting holes 1-311 are respectively provided on the four second connecting parts 2-120, and the four second limiting protrusions 1-400 are provided on the two moving spring pieces 3110 of the moving spring assembly 3100, and a second limiting protrusion 1-400 is respectively provided at both ends of a moving spring piece 3110.

[0418] It can be understood that, in other embodiments, the second anti-rotation structure 1-400 may also include a riveted structure, a welded structure, an adhesive structure, etc. When the second anti-rotation structure 1-400 is a riveted structure, the third base 2-110 is riveted to the push rod assembly 3200; when the second anti-rotation structure 1-400 is a welded structure, the third base 2-110 is welded to the push rod assembly 3200; when the second anti-rotation structure 1-400 is an adhesive structure, the third base 2-110 is adhesively bonded to the push rod assembly 3200.

[0419] In another embodiment, the second anti-rotation structure 1-400 may further include a fastener, which fastens the third elastic spring 2-100 and the dynamic spring assembly 3100.

[0420] It is understandable that the first anti-rotation structure 1-200 and the second anti-rotation structure 1-400 may be the same or different. For example, the first anti-rotation structure 1-200 and the second anti-rotation structure 1-400 may both be position-limiting connection structures or fixed connection structures; or, the first anti-rotation structure 1-200 is a position-limiting connection structure, and the second anti-rotation structure 1-400 is a fixed connection structure.

[0421] In one embodiment, the elastic component 3300 is connected to the movable spring component 3100 in the first direction D1 at an upper limit position; and / or the elastic component 3300 is connected to the push rod component 3200 in the first direction D1 at an upper limit position. In this way, the amplitude of the movable spring component 3100 relative to the push rod component 3200 in the first direction D1 can be reduced, thereby improving the overall impact resistance of the relay.

[0422] Preferably, the elastic component 3300 is connected to the dynamic spring component 3100 in the first direction D1, and the elastic component 3300 is connected to the push rod component 3200 in the first direction D1. In this way, when the relay encounters a large impact, the moving contact and the static contact will not shift, avoiding unstable contact resistance.

[0423] In another embodiment, if Fig.74 and Fig.75 As shown, each second limiting hole 1-311 of the second anti-rotation structure 1-400 is elliptical in shape, and the major axis of the ellipse is parallel to the first direction D1. By designing the second limiting hole 1-311 to be elliptical, before the moving and static contacts come into contact, the second limiting protrusion 1-400 is limited to the outer edge of the second limiting hole 1-311, so that the dynamic spring assembly 3100 will not move (such as Fig.74 ). After the moving and static contacts are in contact, the third elastic spring 2-100 is compressed, and the second connecting parts 2-120 and the second deformation parts 130 on both sides of the third base 2-110 have a tendency to move to both sides. At this time, the elliptical second limiting hole 1-311 can provide space for the second connecting part 2-120 to move, so as to release the stress generated inside the third elastic spring 2-100 after being compressed, so as to prevent the internal stress of the third elastic spring 2-100 from being too concentrated and affecting its service life.

[0424] In addition, it is worth mentioning that since the distance that the second connecting part 2-120 moves within the ellipse is small, it will not affect the relative position of the moving contact and the static contact.

[0425] like Fig.69 and Fig.70 As shown, the similarities between the dynamic component of the twenty-fourth embodiment of the present application and the dynamic component of the twenty-third embodiment are no longer repeated, and the difference lies in that the second connecting parts 2-120 on both sides of the third base 2-110 are connected to the two ends of the second magnetic conductor 6200 along the first direction D1 through the second anti-rotation structure 1-400.

[0426] Each second deformation portion 130 of the third elastic spring 2-100 includes a fourth section 134 and a fifth section 135. One end of the fourth section 134 is connected to the third base 2-110. The fifth section 135 is arc-shaped, and one end of the fifth section 135 is connected to the other end of the fourth section 134; the fifth section 135 extends from the fourth section 134 along an arc-shaped trajectory to the second connection portion 2-120; wherein the second connection portions 2-120 on both sides of the third base 2-110 extend from the fifth section 135 in a direction close to each other.

[0427] Furthermore, a second bending connection 137 is formed between the fifth section 135 and the fourth section 134, and a third bending connection 138 is formed between the fifth section 135 and the second connection portion 2-120. Along the second direction D2, the second bending connection 137 and the third bending connection 138 correspond in position.

[0428] like Fig.71 As shown, the similarities between the moving assembly of the twenty-fifth embodiment of the present application and the moving assembly of the twenty-third embodiment are not repeated, and the difference is that the moving spring assembly 3100 includes a moving spring piece 3110 and a second magnetic conductor 6200, and the relay includes a third elastic spring piece 2-100. Each side of the third base portion 2-110 of the third elastic spring piece 2-100 is provided with a second connecting portion 2-120 and a second deformation portion 130.

[0429] In addition, the two first limiting protrusions 3214 of the first anti-rotation structure 1-200 may also be arranged along the first direction D1.
