Description

Technical Field

[0001] This utility model relates to the field of control switch technology, and more particularly to relays. Background Technology

[0002] A push-rod relay typically includes a base, coil, armature, yoke, stationary spring, moving spring, and actuator; the working principle of this type of push-rod relay is:

[0003] When the coil leads are energized, the excitation current of the coil will generate magnetic flux. The magnetic flux forms a magnetic circuit through the iron core, armature, yoke and working air gap, and generates electromagnetic attraction in the working air gap.

[0004] When the excitation current rises to the set value, the electromagnetic attraction torque will overcome the counter torque of the moving spring, causing the armature to swing on the yoke, generating a pushing force on the pusher towards the moving spring. The pusher pushes the spring laterally, causing the moving contact of the moving spring to close with the stationary contact of the stationary spring.

[0005] When the excitation current decreases to the set value, the reaction torque of the moving reed is greater than the electromagnetic attraction torque, generating a pushing force on the pusher card towards the coil side. The pusher card pushes the armature laterally, causing the armature to return to its initial state. The moving contact of the moving reed disconnects from the stationary contact of the stationary reed. However, at this time, the moving reed will experience a rebound problem due to the release of its own elastic potential energy, that is, the moving reed will swing back and forth relative to the stationary reed. This will cause an arcing problem between the moving and stationary reeds, thus affecting the service life of the relay.

[0006] To address the arcing issue caused by the return of the moving reed, current push-rod relays primarily employ methods such as increasing the contact gap or enhancing the reaction force of the moving reed. However, these methods have significant drawbacks: Firstly, increasing the contact gap sacrifices product space, which is unacceptable given the current trend towards miniaturization in electronic devices; furthermore, a larger contact gap reduces contact stability. Secondly, increasing the reaction force of the moving reed reduces the connection stability between the moving and stationary contacts during closure, thus affecting product performance. Furthermore, neither of these methods can be applied to products with high sensitivity requirements, as they alter the relay's original performance parameters, leading to a decrease in sensitivity. Utility Model Content

[0007] The purpose of this utility model is to provide a relay that solves the problems of sacrificing product space, reducing connection stability, and being unable to be applied to sensitive products when solving the problem of the moving reed's release and rebound in existing push rod relays. It effectively suppresses the release and rebound of the moving reed, and improves the service life and performance of the relay.

[0008] The technical solution adopted by this utility model to solve its problem is:

[0009] A relay includes: a base; an electromagnetic assembly disposed on the base; a contact assembly including a movable spring and a stationary spring vertically disposed on the base; and a pusher slidably disposed on the base, one lateral end of the pusher abutting against the movable spring, the other lateral end of the pusher being connected to an armature in the electromagnetic assembly, and the other lateral end of the pusher also having a pressing portion; in a de-energized state where the electromagnetic assembly is de-energized, when the pressing portion abuts against the base or the yoke in the electromagnetic assembly, the pusher is driven to rotate relative to the movable spring, causing the vertical tip of the pusher to approach or abut against the vertical tip of the movable spring.

[0010] By adopting the above scheme, in the de-excited state, the elastic potential energy stored in the moving reed due to its previous deformation under the electromagnetic force is released and converted into the power to drive the rotating component. When the rotating component starts to rotate, this process continuously consumes the elastic potential energy of the moving reed, thereby fundamentally weakening its rebound amplitude and frequency. At the same time, as the rotating component rotates, the vertical tip of the rotating component gradually approaches or abuts against the vertical tip of the moving reed. At this time, the vertical tip of the rotating component forms a reverse constraint force through contact with the vertical tip of the moving reed. This constraint force directly and effectively suppresses the jumping tendency of the vertical tip of the moving reed, precisely limiting the jumping space and amplitude of the moving reed. Thus, at the physical level, the key function of suppressing release rebound is effectively realized, significantly improving the working stability and reliability of the relay in the de-excited state.

[0011] As an optional implementation, when the electromagnetic component is energized, a travel gap is formed between the vertical top end of the pusher and the vertical top end of the moving spring.

[0012] By adopting the above scheme, in the excited state, the stroke clearance can absorb slight overtravel, avoid hard collisions, protect the component structure, reduce the probability of failure, and extend the service life; in the de-excited state, the moving spring pushes the pusher to move laterally, and the pusher rotates smoothly using the stroke clearance. The vertical top end promptly approaches or abuts the vertical top end of the moving spring, suppressing bounce, reducing the number and amplitude of bounces, reducing the probability of arcing, protecting the contacts, and extending the relay's service life.

[0013] As an optional implementation, the moving spring is provided with a moving contact, the stationary spring is provided with a stationary contact, and the moving contact and the stationary contact are opposite to each other; when the electromagnetic component is energized, the moving contact and the stationary contact attract each other, and the stroke gap is formed between the moving contact and the vertical top end of the pusher.

[0014] By adopting the above scheme, in the excited state, the stroke clearance provides a safety margin for the pusher, which can absorb slight overtravel, avoid hard collisions, protect structural integrity, and reduce the probability of failure. In the de-excited state, the moving spring pushes the pusher to move laterally, and the pusher rotates smoothly using the stroke clearance. The vertical top end approaches or abuts the moving contact in time, suppressing the bouncing of the moving spring and reducing the number and amplitude of bounces.

[0015] As an optional implementation, the point where the lateral end of the pusher abuts against the movable spring is defined as the first abutment point; in the de-energized state of the electromagnetic assembly, the point where the pressing part just begins to abut against the seat or the yoke in the electromagnetic assembly is defined as the second abutment point, and in the direction from the root to the top of the movable spring, the second abutment point is located above the first abutment point.

[0016] By adopting the above scheme, the direction of the reaction force applied by the seat or yoke to the pressing part forms a certain angle with the direction of the thrust force exerted by the moving spring on the pushing member, that is, the direction of the reaction force is inclined to the direction of the thrust. Based on the principle of mechanics, the inclined reaction force can be decomposed into a component force perpendicular to the direction of the thrust force. This component force can drive the pushing member to rotate relative to the moving spring about a certain axis, ultimately causing the vertical tip of the pushing member to move closer to or achieve close contact with the vertical tip of the moving spring.

[0017] As an optional implementation, the pressing part has a first pressing surface facing the seat or the yoke, and the seat or the yoke has a second pressing surface for pressing against the first pressing surface; in the de-energized state of the electromagnetic component, when the first pressing surface and the second pressing surface just begin to contact, the first pressing surface is inclined to the second pressing surface, and the first pressing surface and the second pressing surface are in line contact.

[0018] By adopting the above scheme, the line contact design enables the pressure part to quickly obtain driving force after power failure, the pushing part to rotate rapidly, and the vertical top to quickly approach or abut the moving contact.

[0019] As an optional implementation, in the de-energized state of the electromagnetic component, the pressing part can drive the pushing member to rotate relative to the moving spring until the first pressing surface and the second pressing surface form surface contact, at which point the first pressing surface and the second pressing surface are relatively stationary, and the pushing member stops rotating.

[0020] By adopting the above scheme, the first pressing surface and the pressing surface change from line contact to surface contact, the pushing component rotates smoothly, avoids violent vibration and rebound of the moving spring, and effectively suppresses the generation and development of electric arc.

[0021] As an optional implementation, a insertion groove is formed on the side of the pressing part that is opposite to the first pressing surface, and one end of the armature is connected to the insertion groove.

[0022] By adopting the above scheme, the insertion slot can avoid the armature interfering with the contact between the pressing part and the second pressing surface, accurately position and fix the armature, eliminate the risk of it touching the contact area when moving, ensure that the pressing part accurately presses according to the design, and the pushing part rotates at a predetermined angle and force, so that the vertical top of the pushing part stably approaches or abuts the vertical top of the moving spring (moving contact).

[0023] As an optional implementation, one lateral end of the pusher protrudes toward the movable spring and forms an arc-shaped boss, with the waist of the movable spring abutting against the arc-shaped boss.

[0024] By adopting the above solution, the arc-shaped boss can accurately guide the movement of the moving spring, ensure stable contact, reduce the risk of transmission failure, and improve the accuracy and reliability of the movement. In addition, the arc design makes the contact area distribution reasonable, realizes the uniform transmission of force, avoids excessive local stress on the moving spring, deformation and damage, extends its life, and ensures stable force transmission of the pusher. Furthermore, when the moving spring bounces back during de-excitation, the arc-shaped boss can more effectively cooperate with the movement of the pusher, accurately guide the relative rotation, and enhance the effect of suppressing bounce.

[0025] As an optional implementation, the arc-shaped boss is provided with a first limiting structure, and the waist of the movable spring is provided with a second limiting structure, and the first limiting structure and the second limiting structure are engaged with each other.

[0026] By adopting the above scheme, when the excitation state is reached, the moving spring bounces back. The limiting structure makes the interaction between the moving spring and the pusher more close and rapid. The pusher can suppress the bounce of the moving spring in a timely and effective manner through the vertical top end, and also restrict its multi-directional motion freedom, enhance the bounce suppression capability, reduce the arcing of the moving and stationary springs, and extend the contact life.

[0027] As an optional implementation, the first limiting structure is a limiting post, and the second limiting structure is a limiting groove, with the limiting post being engaged in the limiting groove.

[0028] By adopting the above scheme, the moving spring bounces back when the excitation is deactivated. The limiting post is constrained by the side wall of the limiting groove, which restricts its multi-directional motion freedom. In addition, the vertical top end of the pusher has a suppressive effect and a snap-fit ​​constraint, which works together to effectively reduce the bounce amplitude and speed of the moving spring, reduce the risk of arcing of the moving and stationary springs, and extend the contact life.

[0029] As an optional implementation, when the electromagnetic component is de-energized and the pressing part abuts against the base or the yoke in the electromagnetic component, the pushing member is driven to rotate relative to the moving spring, so that the vertical tip of the pushing member forms an elastic abutment with the vertical tip of the moving spring.

[0030] By adopting the above scheme, this elastic contact can consume the rebound energy of the moving spring, slow down its rebound speed and amplitude, reduce the number and intensity of release rebounds, reduce the probability of arc generation, and extend the contact life.

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0032] The relay provided by this utility model, in the de-energized state of the electromagnetic component, firstly, utilizes the elastic potential energy of the moving spring to drive the rotating component. During the rotation of the rotating component, a portion of the elastic potential energy of the moving spring is consumed, thereby reducing the kinetic energy of the moving spring and lowering its rebound amplitude and frequency. Secondly, since the vertical tip of the rotating component approaches or abuts against the vertical tip of the moving spring, the vertical tip of the rotating component can suppress the bounce of the vertical tip of the moving spring, limiting the bounce of the moving spring and effectively achieving the function of suppressing release bounce, reducing the arcing phenomenon between the moving and stationary springs, and extending the relay life. Regarding the lifespan of the device, and thirdly, compared with increasing the contact gap, the structure of this application does not require additional product space, which can meet the development needs of miniaturization of electronic devices. Furthermore, compared with increasing the reaction force of the moving spring, the structure of this application does not reduce the connection stability when the moving and stationary contacts are closed, which can ensure the performance of the product. In addition, the structure of this application has little impact on the original performance parameters of the relay, and can be applied to products with high sensitivity requirements, expanding the application range of the product. Moreover, the function of suppressing the rebound of the moving spring can be achieved without adding components. The structure is simple, the function is easy to implement, and the production cost is low. Attached Figure Description

[0048] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0049] Please see Figure 1 , Figure 3 and Figure 4 This application provides a relay, which includes a base 1, an electromagnetic component 2, a contact component 3, and a pusher 4. The electromagnetic component 2 is disposed on the base 1. The contact component 3 includes a moving spring 31 and a stationary spring 32 disposed vertically on the base 1. The pusher 4 is slidably disposed on the base 1 in a horizontal direction. One horizontal end of the pusher 4 abuts against the moving spring 31, and the other horizontal end of the pusher 4 is connected to the armature 22 in the electromagnetic component 2. The other horizontal end of the pusher 4 is also provided with a pressing part 41. In the de-energized state of the electromagnetic component 2, when the pressing part 41 abuts against the base 1 or the yoke 23 in the electromagnetic component 2, the pressing part 41 can drive the pusher 4 to rotate relative to the moving spring 31, so that the vertical top end of the pusher 4 approaches or abuts against the vertical top end of the moving spring 31.

[0050] The relay provided in this application embodiment, in the de-energized state of the electromagnetic component 2, firstly, utilizes the elastic potential energy of the movable spring 31 to drive the pusher 4 to rotate. During the rotation of the pusher 4, a portion of the elastic potential energy of the movable spring 31 is consumed, thereby reducing the kinetic energy of the movable spring 31 and decreasing its rebound amplitude and frequency. Secondly, since the vertical tip of the pusher 4 approaches or abuts against the vertical tip of the movable spring 31, the vertical tip of the pusher 4 can suppress the bounce of the vertical tip of the movable spring 31, limiting the bounce of the movable spring 31, effectively achieving the function of suppressing release bounce, and reducing the arcing phenomenon between the movable spring 31 and the stationary spring 32. Firstly, it extends the service life of the relay. Secondly, compared with increasing the contact gap, the structure of this application does not require additional product space, which can meet the development needs of miniaturization of electronic devices. Moreover, compared with increasing the reaction force of the moving spring 31, the structure of this application will not reduce the connection stability when the moving contact 311 and the stationary contact 321 are closed, which can ensure the performance of the product. In addition, the structure of this application has little impact on the original performance parameters of the relay, and can be applied to products with high sensitivity requirements, expanding the application range of the product. Furthermore, the function of suppressing the rebound of the moving spring 31 can be achieved without adding components. The structure is simple, the function is easy to implement, and the production cost is low.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the electromagnetic component 2 includes a coil 21, a yoke 23, and an armature 22. The coil 21 is fixedly mounted on the base 1, the yoke 23 is fixedly mounted on the base 1, and the armature 22 is movably mounted on the base 1 and is connected to the transverse end of the pusher 4 for transmission.

[0052] In some embodiments, when the coil 21 of the electromagnetic component 2 is de-energized and de-excited, the excitation current decreases to a set value, the reaction torque of the moving spring 31 is greater than the electromagnetic attraction torque, and the pushing member 4 is subjected to a pushing force towards the coil 21. The pushing member 4 laterally pushes the armature 22, causing the armature 22 to return to its initial state, and the moving contact 311 of the moving spring 31 and the stationary contact 321 of the stationary spring 32 begin to separate. During the release of the elastic potential energy of the moving spring 31, the moving spring 31 will have a tendency to bounce back. At this time, the pressing part 41 on the pushing member 4 abuts against the yoke 23 in the base 1 or the electromagnetic component 2, such as... Figure 3 and Figure 4 As shown, the pressing part 41 is subjected to the reaction force of the seat 1 or the yoke 23, which drives the pushing member 4 to rotate relative to the moving spring 31. After the pushing member 4 rotates, its vertical tip approaches or abuts against the vertical tip of the moving spring 31, which inhibits the vertical tip of the moving spring 31, limits the bounce of the moving spring 31, and thus effectively suppresses the release rebound and reduces the arcing phenomenon between the moving spring 31 and the stationary spring 32.

[0053] In some embodiments, when the coil 21 of the electromagnetic component 2 is de-energized, the pressing part 41 can press against the limiting post integrally formed on the base 1, or the pressing part can press against the limiting member that is otherwise fixedly provided on the base 1.

[0054] In some embodiments, when the coil 21 of the electromagnetic component 2 is de-energized and de-excited, the pressing part 41 can directly press against the yoke 23 to save space and reduce the number of parts.

[0055] like Figure 2 As shown, in some embodiments, when the coil 21 of the electromagnetic component 2 is energized, the magnetic flux generated by the excitation current forms a magnetic circuit through the iron core, armature 22, yoke 23, and working air gap, and generates electromagnetic attraction in the working air gap. When the excitation current rises to a set value, the electromagnetic attraction torque overcomes the counter-torque of the moving spring 31, causing the armature 22 to swing on the yoke 23, driving the pusher 4 to move laterally. The pusher 4 laterally pushes the spring 31, causing the moving contact 311 of the moving spring 31 to close with the stationary contact 321 of the stationary spring 32, and the circuit is connected. At this time, a travel gap 5 is formed between the vertical top end of the pusher 4 and the vertical top end of the moving spring 31. This travel gap 5 can avoid problems caused by the overtravel of the pusher 4. For details, please refer to [reference needed]. Figure 2As shown. It is understandable that, under energized conditions, to ensure a good closure between the stationary contact 321 of the stationary spring 32 and the moving contact 311 of the moving spring 31, the pusher 4 needs to be designed to allow for overtravel. If there is no travel clearance 5 between the pusher 4 and the moving spring 31, the overtravel of the pusher 4 will cause it to directly impact the moving spring 31, resulting in structural deformation, wear, or even breakage. The travel clearance 5 in this embodiment provides a safe movement margin for the pusher 4. Firstly, when a slight overtravel occurs, the travel clearance 5 can absorb the excess travel, preventing a hard collision between the pusher 4 and the moving spring 31, protecting the structural integrity of key components, reducing the probability of relay failure due to mechanical damage, and extending product lifespan. Secondly, the travel clearance 5 design in this embodiment ensures that the pressure applied by the pusher 4 to the moving spring 31 is stable and moderate, ensuring tight and uniform contact between the moving contact 311 and the stationary contact 321, with low and stable contact resistance, thereby... The electrical performance and operational reliability of the relay are improved, and circuit faults caused by poor contact are reduced. Thirdly, in the de-energized state of the coil 21 of the electromagnetic component 2, when the moving spring 31 applies a lateral thrust to the pusher 4, the pusher 4 can smoothly rotate relative to the moving spring 31 using the stroke gap 5. The vertical top of the pusher 4 promptly approaches or abuts the vertical top of the moving spring 31, effectively suppressing the bounce of the moving spring 31, reducing the number and amplitude of bounces, thereby reducing the probability of arcing, protecting the contacts from arc erosion, and significantly extending the service life of the relay.

[0056] like Figure 1 and Figure 2As shown, in some embodiments, the moving spring 31 is provided with a moving contact 311, and the stationary spring 32 is provided with a stationary contact 321. The moving contact 311 and the stationary contact 321 are opposite to each other. When the coil 21 of the electromagnetic component 2 is energized, the moving contact 311 and the stationary contact 321 attract each other, and the stroke gap 5 is formed between the moving contact 311 and the vertical top end of the pusher 4. With this configuration, firstly, the pusher 4 needs to be designed to allow for overtravel sliding. If there is no reasonable travel gap 5 between the vertical top of the pusher 4 and the moving contact 311, the overtravel sliding of the pusher 4 will cause the pusher 4 to directly impact the moving contact 311, thereby impacting the moving spring 31, causing structural deformation, weakened elasticity, or even breakage of the moving spring 31, which seriously affects the mechanical performance and service life of the relay. The travel gap 5 formed in this embodiment provides a safe movement margin for the pusher 4. When a slight overtravel occurs, the travel gap 5 can absorb the excess travel, preventing the pusher 4 from having a hard collision with the moving contact 311, protecting the structural integrity of the moving spring 31 and the moving contact 311, reducing the probability of relay failure due to mechanical damage, and ensuring the stability of the mechanical structure of the relay during long-term use. Secondly, when the coil 21 of the electromagnetic component 2 is de-energized and in the de-excitation state, when the moving spring 31 applies a lateral thrust to the pusher 4, the pusher 4 can smoothly rotate relative to the moving spring 31 using the stroke gap 5. The vertical top of the pusher 4 promptly approaches or abuts the moving contact 311 of the moving spring 31, effectively suppressing the bounce of the moving spring 31, reducing the number and amplitude of bounces, thereby reducing the probability of arcing, protecting the contacts from arc erosion, and significantly extending the service life of the relay.

[0057] like Figure 3 As shown, in some embodiments, the point where the lateral end of the pusher 4 abuts against the movable spring 31 is defined as the first abutment point A; in the de-energized state of the electromagnetic assembly 2, the point where the pressing part 41 and the yoke 23 in the seat 1 or electromagnetic assembly 2 just begin to abut is defined as the second abutment point B. In the direction from the root to the top of the movable spring 31, the second abutment point B is located above the first abutment point A. For details, please refer to [reference needed]. Figure 3 As shown, the reaction force of the seat 1 or yoke 23 on the pressing part 41 is tilted to the direction of the thrust of the moving spring 31 on the pushing member 4. The reaction force of the seat 1 or yoke 23 on the pressing part 41 forms a certain angle with the thrust of the moving spring 31 on the pushing member 4. Based on the principle of mechanics, the tilted reaction force can be decomposed into a component force perpendicular to the thrust direction. This component force can drive the pushing member 4 to rotate relative to the moving spring 31 around a certain axis, ultimately causing the vertical top of the pushing member 4 to approach or achieve close contact with the vertical top of the moving spring 31.

[0058] like Figure 3 and Figure 5 As shown, in some embodiments, the pressing part 41 has a first pressing surface 411 facing the base 1 or the yoke 23, and the base 1 or the yoke 23 has a second pressing surface 231 for pressing against the first pressing surface 411; in the de-energized state of the electromagnetic component 2, when the first pressing surface 411 and the second pressing surface 231 first come into contact, the first pressing surface 411 is inclined to the second pressing surface 231, and the first pressing surface 411 and the second pressing surface 231 are in line contact, as detailed in the reference. Figure 3 As shown in the diagram; with this configuration, when the coil 21 of the electromagnetic component 2 is de-energized and enters the de-excitation state, the line contact design between the first pressing surface 411 and the second pressing surface 231 provides the pressing part 41 with a fast-response driving force, which can generate a sufficiently large local force in a very short time, causing the pressing part 41 to move quickly. This fast-response mechanism enables the pusher 4 to immediately obtain the driving force for rotation, thereby causing the vertical top end of the pusher 4 to quickly approach or abut against the vertical top end (moving contact 311) of the moving spring 31.

[0059] like Figure 4 As shown, in some embodiments, in the de-energized state of the electromagnetic component 2, the pressing part 41 can drive the pushing member 4 to rotate relative to the moving spring 31 until the first pressing surface 411 and the second pressing surface 231 form surface contact. At this point, the first pressing surface 411 and the second pressing surface 231 are relatively stationary, and the pushing member 4 stops rotating. With this configuration, the rotation of the pushing member 4 relative to the moving spring 31 is a gradual and smooth process as it transitions from inclined line contact to surface contact. This smooth transition avoids the violent vibration and rebound of the moving spring 31 caused by sudden force. Due to the smooth movement, the generation and development of the electric arc are further effectively suppressed.

[0060] It should be noted that in some other embodiments, the first pressing surface 411 may be, but is not limited to, an arc surface. In this case, the first pressing surface 411 and the second pressing surface 231 are always in line contact. This can be set according to actual needs.

[0061] like Figure 2 and Figure 3As shown, in some embodiments, a insertion groove 412 is formed on the side of the pressing part 41 opposite to the first pressing surface 411. One end of the armature 22 is connected to the insertion groove 412. The design of the insertion groove 412 can prevent the armature 22 from interfering with the contact between the pressing part 41 and the second pressing surface 231. In this way, the insertion groove 412 accurately positions and fixes the armature 22, preventing the armature 22 from accidentally touching the contact area between the pressing part 41 and the second pressing surface 231 due to positional deviation or shaking during movement, thus completely eliminating the risk of movement interference. This ensures that the pressing part 41 can make complete and accurate pressing contact with the second pressing surface 231 according to the design requirements, so that the pushing member 4 rotates according to the predetermined angle and force, thereby making the vertical top end of the pushing member 4 stably approach or abut against the vertical top end (moving contact 311) of the moving spring 31.

[0062] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the lateral end of the pusher 4 protrudes towards the movable spring 31 to form an arc-shaped boss 42, and the waist of the movable spring 31 abuts against the arc-shaped boss 42. This configuration has two advantages: First, it provides a clear and stable contact position for the movable spring 31 and the pusher 4. The waist of the movable spring 31 precisely abuts against the arc-shaped boss 42. Compared with a flat or irregularly shaped contact surface, the arc-shaped boss 42 can better guide the movement of the movable spring 31, ensuring that the contact between the movable spring 31 and the pusher 4 remains stable during various operations, including normal operation and de-energization of the relay. This reduces the risk of transmission failure due to misalignment or instability of the contact position and improves the accuracy and reliability of the relay operation. Second, the arc-shaped design of the arc-shaped boss 42 makes the contact area distribution between the waist of the movable spring 31 and the pusher 4 more reasonable. When the pusher 4 applies a force to the movable spring 31 or the movable spring 31 generates a reaction force on the pusher 4, the force can be transmitted evenly. This uniform force transmission method effectively avoids excessive local force on the moving spring 31, which could lead to deformation or damage, thus extending its service life. It also ensures that the pusher 4 can reliably and stably transmit force to the moving spring 31, enabling the relay contacts to close and open normally. Thirdly, the arc-shaped boss 42 structure further optimizes the transmission and interaction between the moving spring 31 and the pusher 4. In the de-excitation state, when the moving spring 31 rebounds, the arc-shaped boss 42 can more effectively coordinate with the overall movement of the pusher 4, providing more precise guidance for the relative rotation between the moving spring 31 and the pusher 4. This enhances the suppression effect on the release and rebound of the moving spring 31. By reducing the amplitude and speed of the rebound of the moving spring 31, the possibility of arcing between the moving spring 31 and the stationary spring 32 is further reduced, extending the service life of the relay contacts and improving the overall reliability and stability of the relay.

[0063] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the arc-shaped boss 42 is provided with a first limiting structure 43, and the waist of the moving spring 31 is provided with a second limiting structure 312. The first limiting structure 43 and the second limiting structure 312 are engaged. With this configuration, firstly, during relay operation, an interaction force is generated between the moving spring 31 and the pusher 4. This force may cause stress concentration at the connection point, leading to fatigue damage of the component. The engagement of the arc-shaped boss 42 with the limiting structure at the waist of the moving spring 31 can effectively disperse stress concentration, distributing the force evenly on the engagement surface, reducing excessive local stress. Through this stress dispersion mechanism, the engagement structure can withstand greater forces without damage, improving the strength and durability of the relay structure. Secondly, in the de-energized state, when the moving spring 31 rebounds due to the release of elastic potential energy, the engagement structure allows for a closer and faster interaction between the moving spring 31 and the pusher 4. When the pusher 4 is subjected to the rebound force of the moving spring 31, it can more promptly and effectively engage the spring 31 through the vertical top end. The moving spring 31 is suppressed, and the locking structure also restricts the moving spring 31's freedom of movement in multiple directions, enhancing the overall ability to suppress the rebound of the moving spring 31. This more effectively reduces the arcing phenomenon between the moving spring 31 and the stationary spring 32, extending the service life of the relay contacts. Furthermore, the locking structure ensures good stability in the connection between the pusher 4 and the moving spring 31 during the rebound of the moving spring 31. This stability makes the suppression effect of the pusher 4 on the rebound of the moving spring 31 more continuous and reliable, and the suppression effect will not weaken due to changes in the relative position between the moving spring 31 and the pusher 4. No matter how the amplitude and frequency of the rebound of the moving spring 31 change, the locking structure can ensure that the pusher 4 accurately performs its suppression function, improving the stability and reliability of the relay's suppression and release rebound function.

[0064] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the first limiting structure 43 is a limiting post, and the second limiting structure 312 is a limiting groove, with the limiting post engaging within the limiting groove. Thus, in the de-excitation state, when the moving spring 31 rebounds due to the release of elastic potential energy, the limiting post is constrained by the sidewall within the limiting groove, restricting the moving spring 31's degrees of freedom in multiple directions. Simultaneously, the suppressive effect of the vertical top of the pushing member 4 on the moving spring 31, combined with the engaging constraint of the "limiting post-limiting groove," effectively reduces the rebound amplitude and speed of the moving spring 31, thereby reducing the possibility of arcing between the moving spring 31 and the stationary spring 32 and extending the contact's service life.

[0065] It should be noted that in some other embodiments, the first limiting structure 43 may be, but is not limited to, a hook, and the second limiting structure 312 may be correspondingly set as a slot, with the hook engaging in the slot.

[0066] like Figure 4 As shown, in some embodiments, when the electromagnetic component 2 is de-energized and the pressing part 41 abuts against the base 1 or the yoke 23 in the electromagnetic component 2, the driving member 4 rotates relative to the moving spring 31, causing the vertical tip of the driving member 4 to form an elastic abutment against the vertical tip of the moving spring 31. Thus, since the moving spring 31 itself can undergo elastic deformation, the vertical tip of the driving member 4 can form an elastic abutment against the vertical tip of the moving spring 31. This elastic abutment between the vertical tip of the driving member 4 and the vertical tip of the moving spring 31 (moving contact 311) can consume some of the energy used by the moving spring 31 for rebound, slowing down its rebound speed and amplitude, thereby effectively reducing the number and intensity of release rebounds, reducing the probability of arc generation, and extending the contact life.

[0067] In summary, the relay disclosed in the embodiments of this application can bring at least the following beneficial technical effects:

[0068] (1) In the de-excitation state, the elastic potential energy of the moving spring 31 is used to drive the pusher 4 to rotate. During the rotation of the pusher 4, a portion of the elastic potential energy of the moving spring 31 will be consumed, thereby reducing the kinetic energy of the moving spring 31, reducing its rebound amplitude and frequency, and the function of suppressing the rebound of the moving spring 31 can be achieved without adding parts. The structure is simple, the function is easy to implement, and the production cost is low.

[0069] (2) In the de-excitation state, since the vertical tip of the pusher 4 is close to or abuts against the vertical tip of the moving spring 31, the vertical tip of the pusher 4 can suppress the bounce of the vertical tip of the moving spring 31, limit the bounce of the moving spring 31, and effectively realize the function of suppressing release bounce.

[0070] (3) When the de-excitation state is reached, the line contact design between the first pressing surface 411 and the second pressing surface 231 provides the pressing part 41 with a fast-response driving force, which can generate a sufficiently large local force in a very short time, causing the pressing part 41 to move quickly. This fast-response mechanism enables the pusher 4 to immediately obtain the driving force for rotation, thereby causing the vertical top of the pusher 4 to quickly approach or abut against the vertical top of the moving spring 31 (moving contact 311).

[0071] (4) A insertion groove 412 is formed on the side of the pressing part 41 that is opposite to the first pressing surface 411. One end of the armature 22 is connected to the insertion groove 412. The design of the insertion groove 412 can prevent the armature 22 from interfering with the contact between the pressing part 41 and the second pressing surface 231.
