Description

Technical Field

[0001] This application relates to the field of relay technology, and more particularly to a relay. Background Technology

[0002] A relay is a widely used component in electrical control and automation systems, primarily composed of a stationary electrode and a moving electrode. The moving electrode interacts with the stationary electrode via a spring mechanism to achieve switching control. However, in traditional moving electrode structures, the spring typically acts directly on an insulating block. When an external impact is applied to this structure, the insulating block, due to its relatively low strength, is easily damaged after absorbing the impact force. This can lead to unstable contact between the moving and stationary electrodes, thereby affecting the reliability of the relay. Utility Model Content

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] A relay is a widely used component in electrical control and automation systems, primarily composed of a stationary electrode and a moving electrode. The moving electrode interacts with the stationary electrode via a spring mechanism to achieve switching control. However, in traditional moving electrode structures, the spring typically acts directly on an insulating block. When an external impact is applied to this structure, the insulating block, due to its relatively low strength, is easily damaged after absorbing the impact force. This can lead to unstable contact between the moving and stationary electrodes, thereby affecting the reliability of the relay.

[0060] To solve the above problems, see Figures 1 to 9 As shown, this utility model embodiment provides a relay 10, which includes a mounting component 100, a moving electrode 200, a movable component 300, a driving component 400, and a stationary electrode 500. The mounting component 100 serves as a mounting carrier to mount other components of the relay 10 and facilitates connection between the relay 10 and external components. The stationary electrode 500 is connected to the mounting component 100. The moving electrode 200 is movably disposed relative to the stationary electrode 500. The movable component 300 includes a frame structure 310, an elastic element 320, and an iron core structure 330. The frame structure 310 is connected to the iron core structure 330, and the frame structure 310 has an internal movable space. The moving electrode 200 is at least partially movably disposed within the movable space. The elastic element 320 is connected to both the moving electrode 200 and the frame structure 310 to ensure a good elastic connection between them. The driving component 400 is connected to the mounting component 100 and is magnetically connected to the iron core structure 330 to drive the moving electrode 200 to contact or separate from the stationary electrode 500.

[0061] The relay 10 of this embodiment significantly improves the reliability of the relay 10 under external impact by introducing a combination of frame structure 310 and elastic element 320 in the active component 300.

[0062] Specifically, compared to the traditional relay 10, the relay 10 of this embodiment, by configuring the elastic element 320 to be connected to the moving electrode 200 and the frame structure 310 respectively, can avoid the elastic element 320 directly acting on the iron core structure 330 (the insulating block in the traditional relay), thereby effectively dispersing the impact force transmitted to the iron core structure 330, avoiding damage to the iron core structure 330, and thus improving the reliability of the relay 10; in addition, by placing the elastic element 320 inside the frame structure 310, the overall structure of the relay 10 can also be made compact.

[0063] In some embodiments, the type of elastic element 320 may include, but is not limited to, springs, rubber, or elastic elements made of other materials, each of which has its own advantages. For example, springs have good elasticity and resilience, while rubber has the best energy absorption performance and insulation. The use of elastic elements made of different materials can be selected according to actual design requirements, and no single limitation is made here.

[0064] When using the relay 10 of this embodiment, the moving electrode 200 and the stationary electrode 500 can initially be separated. This process is triggered by the drive assembly 400, which drives the moving assembly 300 to move the moving electrode 200 toward the stationary electrode 500. When the moving electrode 200 begins to move, the first contact it makes is with the stationary electrode 500. During this contact process, the elastic element 320 plays a crucial role, effectively adapting to the movement trajectory of the moving electrode 200.

[0065] Specifically, when the moving electrode 200 contacts the stationary electrode 500, the elastic element 320 continuously compresses as contact occurs. The force it applies is dynamic, gradually increasing with the increase of contact surface pressure. This means that the elastic element 320 has excellent adjustment capability in maintaining contact between the moving electrode 200 and the stationary electrode 500, ensuring that they maintain a tight contact under optimal mechanical conditions. Through this design, the contact surface between the moving electrode 200 and the stationary electrode 500 can effectively reduce electrical contact resistance and improve current conduction efficiency.

[0066] Based on the characteristics of the elastic element 320, the applied pressure can be automatically adjusted according to the actual movement, thereby avoiding poor connection or premature wear caused by excessive or insufficient pressure. For example, when the moving electrode 200 moves at a faster speed, the elastic element 320 can increase the applied pressure to ensure effective contact with the stationary electrode 500. When the speed is slower or the contact is stable, the elastic element 320 can appropriately reduce the pressure to prevent burn-out or fatigue failure of the contact points due to prolonged contact.

[0067] This precise mechanical control not only improves the response speed of relay 10 but also extends its service life. In common applications, the reliability of a relay is closely related to the stability of the circuit. The elastic element 320, by applying continuous and uniform pressure, maintains the stability of the electrodes even in the presence of external disturbances, effectively reducing the risk of arcing and contact burnout, and providing a reliable guarantee for the normal operation of the circuit system.

[0068] It should be noted that the number of stationary electrodes 500 is flexible and can be one or more. In some embodiments, there are two stationary electrodes 500, which can be independently connected to the circuit. In this case, when the moving electrode 200 is in contact with both stationary electrodes 500 simultaneously, the relay 10 can achieve the function of circuit conduction. This design not only gives the relay 10 a higher circuit switching capability, but also enhances its adaptability and flexibility in multi-output applications.

[0069] When the moving electrode 200 separates from the two stationary electrodes 500, the circuit is disconnected. This configuration enables effective control of the circuit. In this case, the movement of the moving electrode 200 is not limited to connecting or disconnecting a single circuit, but can control two circuits simultaneously, thereby improving the overall functionality and application scenarios of the relay 10.

[0070] Of course, in some other embodiments, there may be one or more stationary electrodes 500. The number of stationary electrodes 500 can be flexibly varied according to actual needs to achieve different application scenarios. As the number of stationary electrodes 500 increases, the interaction between them and the moving electrode 200 becomes more complex, thereby enabling various complex control functions. For example, increasing the number of stationary electrodes 500 can expand the application range of the relay 10, enabling it to handle more current loops or achieve higher connection reliability.

[0071] Specifically, see Figure 2 and Figure 3 As shown, the core structure 330 includes a core shaft 331 and an insulating block 332. The frame structure 310 is at least partially embedded in the insulating block 332. The core shaft 331 is magnetically connected to the drive assembly 400 and is connected to the insulating block 332.

[0072] Specifically, see Figure 2 and Figure 3As shown, the core structure 330 consists of a spindle 331 and an insulating block 332. The frame structure 310 is at least partially embedded within the insulating block 332 to ensure a stable connection between the frame structure 310 and the insulating block 332. The spindle 331 is connected to the drive assembly 400. The spindle 331 is also connected to the insulating block 332, forming a unified structure. This allows the core structure 330 to provide necessary support and insulation for the elastic element 320 during the operation of the relay 10, and the spindle 331 and the insulating block 332 can be driven by the drive assembly 400 to move the insulating block 332.

[0073] On the other hand, if a split structure is chosen, a certain distance is maintained between the spindle 331 and the frame structure 310, and they are separated by the insulating block 332. This design provides greater flexibility and adjustability. The split structure allows for more complex mechanical configurations and enables optimized adjustments in different types of application environments. For example, in certain high-temperature, high-humidity, or highly corrosive working environments, the split structure design can reduce the thermal conductivity and electrochemical reaction of the iron core, enhancing the durability and stability of the relay 10. In this case, users can flexibly choose between contact or split methods according to the actual working environment and requirements to obtain the best technical performance and usage effect.

[0074] Further, see Figure 3 As shown, the insulating block 332 has a receiving groove 33211 on the side facing the elastic member 320, and the frame structure 310 is at least partially located in the receiving groove 33211. The end of the elastic member 320 away from the moving electrode 200 is accommodated in the receiving groove 33211 and connected to the frame structure 310.

[0075] In this embodiment, one end of the elastic element 320 is disposed within the receiving groove 33211. This design not only facilitates the installation of the elastic element 320 but also effectively connects the frame structure 310, thereby avoiding uneven stress on the spindle 331 during operation. This design concept emphasizes the stability and reliability of the overall structure, ensuring that the relay 10 maintains excellent performance under different operating conditions.

[0076] Specifically, the elastic element 320, positioned within the receiving groove 33211, effectively provides elastic support and achieves a tight fit with the frame structure 310. This connection method ensures that the deformation force and reaction force experienced by the elastic element 320 during operation are primarily borne by the frame structure 310, thereby protecting the spindle 331 from direct mechanical impact and overload damage. The advantage of this design is that it not only reduces the risk of component damage due to improper stress but also effectively extends the lifespan of the structure.

[0077] Meanwhile, the positioning of the elastic element 320 via the receiving slot 33211 ensures its stability and consistent operating condition throughout the entire working cycle. This positioning mechanism also makes the combination of the elastic element 320 and the iron core structure 330 more compact, optimizing the space utilization of the overall structure. This space optimization helps improve the integration of the relay, facilitating high-efficiency electrical connections within confined spaces. In certain applications, the size and installation space of the relay 10 are often key design factors; therefore, this solution undoubtedly has a positive impact on enhancing the product's market competitiveness.

[0078] In one embodiment, the insulating block 332 includes a block body 3321 and a protrusion 3322, a receiving groove 33211 is provided on the block body 3321, a frame structure 310 is at least partially embedded in the block body 3321, and the protrusion 3322 is connected to the block body 3321 and is at least partially accommodated in the receiving groove 33211.

[0079] The elastic element 320 includes a helical spring, which is coaxially arranged with the spindle 331. One end of the helical spring is connected to the moving electrode 200, and the protrusion 3322, the frame structure 310 and the inner wall of the receiving groove 33211 enclose a space for accommodating the other end of the helical spring.

[0080] With the above arrangement, the helical spring of the elastic element 320 can wrap around the protrusion 3322 at the end away from the moving electrode 200, facilitating the positioning of the elastic element 320. The advantage of this design is that the contact between the elastic element 320 and the protrusion ensures its stability during operation, preventing displacement or detachment during movement. Furthermore, the helical spring can also be located solely within the space of the block body 3321 and separated from the protrusion 3322. Specific design schemes should be flexibly adjusted according to the size and shape of the elastic element 320 and the design requirements of the actual application. No single limitation is imposed here; the flexibility and adaptability of the design are emphasized to meet the needs of different product lines and engineering implementations.

[0081] In this embodiment, the receiving groove 33211 on the block body 3321 provides an effective basis for the installation and positioning of the elastic element 320. When the frame structure 310 and the insulating block 332 are integrally formed, the frame structure 310 can be at least partially located within the receiving groove 33211, ensuring good contact between the elastic element 320 and the frame structure 310. This contact not only improves the dynamic response performance but also enhances the bonding force between the elastic element 320 and the frame structure 310, ensuring stability and reliability under different working conditions.

[0082] In some embodiments, the frame structure 310 can even be embedded inside the block body 3321, thus achieving a more compact spatial layout and increasing the effective usable space. It is worth noting that in this embodiment, the inner wall of the receiving groove 33211 and the protrusion 3322 together enclose a space for accommodating the elastic element 320, making the structural design more rational and compact. This design not only minimizes the overall structural volume but also improves the mechanical strength of the device, thereby enhancing the overall performance and stability of the insulating block 332.

[0083] By integrally molding the frame structure 310 and the insulating block 332, and then rationally positioning them according to the actual needs of the elastic element 320, the assembly difficulty between components can be effectively reduced, and the overall production efficiency can be improved. Furthermore, the tight integration of the frame structure 310 and the block body 3321 significantly enhances the durability of the insulating block 332, helping to improve the operational reliability of electrical equipment under high loads and frequent operation.

[0084] Further, see Figure 7 As shown, the protrusion 3322 has an arc-shaped structure 33221 at one end facing the elastic member 320.

[0085] In this embodiment, the curved surface structure 33221 plays a crucial guiding role in the installation of the elastic element 320. Specifically, when the elastic element 320 is connected to the insulating block 332, the curved surface structure 33221 effectively guides the elastic element to the correct position. This design helps avoid functional malfunctions caused by inaccurate positioning during installation, such as uneven force distribution or jamming of the elastic element. By guiding the installation process of the elastic element 320, the ease and accuracy of installation can be significantly improved, thereby reducing assembly time and cost.

[0086] Specifically, the radius of curvature and tangential angle of the arc-shaped structure 33221 can be adjusted to varying degrees according to the specific design and requirements of the elastic element 320. Specifically, if the radius of curvature of the arc-shaped structure 33221 is set within a reasonable range, a smooth installation experience can be achieved. Adjustments can be made based on actual conditions. This design allows the elastic element 320 to better fit and adapt to the existing structure during installation, preventing malfunctions caused by mismatch.

[0087] In different implementation schemes, in addition to the curved surface structure 33221, the protrusion 3322 can also have various forms of guiding features, such as stepped or grooved shapes. These different guiding features can be flexibly selected according to the type and size of the elastic element 320 to further optimize the installation effect. For example, a stepped design can increase the contact area of ​​the connecting surface to a certain extent, which helps to improve structural stability; while a grooved shape helps to achieve better alignment. The combination of these different shapes can be optimized according to requirements.

[0088] Referring to Figure 3, in one embodiment, the spindle 331 includes a shaft body 3311 and a connecting flange 3312. The shaft body 3311 is magnetically connected to the drive assembly 400. The connecting flange 3312 extends outward from the outer wall of the shaft body 3311. The shaft body 3311 passes through the insulating block 332, and the connecting flange 3312 is embedded in the insulating block 332.

[0089] In this embodiment, enhancing the fit between the shaft body 3311 and the insulating block 332 helps to increase their contact area. Specifically, by increasing the contact area, the contact force formed between the connecting flange 3312 and the insulating block 332 will be significantly improved. This enhanced contact area directly leads to an increase in connection strength, enabling the mandrel 331 to withstand greater mechanical stress and vibration in dynamic working environments, thereby improving the overall strength and stability of the core structure 330.

[0090] Furthermore, the design of the connecting flange 3312 not only increases the contact area but also plays a role in positioning and guiding during the assembly of the shaft body 3311 and the insulating block 332. This structure simplifies the positioning process during production, reduces the difficulty for engineers during installation, and lowers production and maintenance costs. Simultaneously, when the mandrel 331 and the insulating block 332 are integrally molded, their molding accuracy can be optimized through rational design, both during injection molding and subsequent assembly.

[0091] Specifically, there are multiple connecting flanges 3312, and the multiple connecting flanges 3312 are spaced apart along the axial direction of the shaft body 3311; and / or the surface of the connecting flanges 3312 is knurled.

[0092] This design with multiple connecting flanges 3312 helps to further increase the contact area with the insulating block 332. By increasing the contact area, a more reliable connection can be achieved, improving connection strength and thus significantly enhancing the overall strength and stability of the core structure 330.

[0093] By incorporating multiple connecting flanges 3312, more contact points are formed on the connecting surface. These contact points disperse the stress acting on the connection, enabling the shaft body 3311 to more effectively withstand mechanical loads and vibrations under dynamic operating conditions. Furthermore, this design reduces localized wear and fatigue in individual connection areas, thereby extending the equipment's service life and reducing the risk of failure due to poor connections.

[0094] Meanwhile, if the surface of the connecting flange 3312 is knurled, it will increase friction and enhance the gripping ability with the insulating block 332, improving the connection stability under static and dynamic loading. The knurled surface not only increases the coefficient of friction but also helps prevent slippage during installation, further improving the ease and accuracy of installation.

[0095] It should be noted that the number of connecting flanges 3312 can be two, three, four, or more, but this is not a fixed limitation. Different numbers of connecting flanges 3312 can provide different connection effects. For example, increasing to three flanges will help to distribute stress more evenly, while increasing to four or more may provide higher reliability and stability. The specific spacing and design of the connecting flanges can be precisely calculated and optimized according to the actual application requirements. Thus, the number and form of the connecting flanges can be flexibly adjusted for specific applications to adapt to different mechanical loads and working environments.

[0096] In some embodiments, at least one of the connecting flanges 3312 is located within the active space.

[0097] This design ensures that when the elastic element 320 is connected to the core structure 330, the connection strength is effectively enhanced by the connecting flange 3312 built into the mandrel 331. This design makes the connection more stable and better adaptable to various load changes under dynamic working conditions, thereby reducing the risk of loosening and detachment.

[0098] Specifically, the connecting flange 3312 located within the movable space can improve the strength of the connection between the mandrel 331 and the elastic member 320 when the core structure 330 is connected to the elastic member 320. Furthermore, placing at least one connecting flange 3312 within the movable space helps to further improve the compactness of the combined structure of the core structure 330 and the elastic member 320.

[0099] Specifically, in the embodiments, see [reference] Figure 8The structure shown includes a first flange 33121 and a second flange 33122 in the connecting flange 33122. The first flange 33121 is disposed within the protrusion 3322, while the second flange 33122 is located within the block body 3321. Because the protrusion 3322 protrudes into the receiving groove 33211, the first flange 33121 is also located within the movable space and is connected to the elastic member 320 through the protrusion 3322.

[0100] By placing the first flange 33121 within the protrusion 3322, the connection strength between the two can be effectively enhanced, thereby increasing the overall strength of the protrusion 3322. The second flange 33122 serves as a reinforcement, forming an integral support structure through its combination with the block body 3321. This configuration effectively disperses the stress applied to the connection between the core structure 330 and the elastic element 320 during operation, making the entire connection system more stable under dynamic loads. The cooperation between the two helps reduce fatigue and wear of the connection parts caused by external forces such as vibration and impact, thereby improving the reliability of the relay 10.

[0101] Therefore, this structural design ensures the overall strength of the core structure 330 at its connection with the elastic element 320 and the insulating block 332. In fact, this rational design enables the entire assembly to withstand greater loads during continuous operation, improving the durability and stability of the equipment.

[0102] In one embodiment, the spindle 331 is threadedly connected to the drive assembly 400.

[0103] This design allows for precise positioning of the mandrel 331 and drive assembly 400, ensuring their coaxiality. It also simplifies the installation process, enabling users to easily connect and assemble the mandrel 331 and drive assembly 400. For example, the threaded connection design allows for rapid rotation, enabling the installation process to be completed in just a few seconds, significantly improving work efficiency.

[0104] Furthermore, due to the excellent mechanical properties of threaded connections, they can effectively withstand the axial loads and torques generated by the drive assembly 400 during operation, thereby ensuring the reliability and stability of the entire assembly. This type of connection performs excellently in dynamic applications, effectively reducing the risk of failure caused by loose connections.

[0105] In other embodiments, the spindle 331 and the drive assembly 400 may also be connected in different ways, such as by welding. By welding the spindle 331 and the drive assembly 400 together, the connection strength between the two can be improved, thereby improving the reliability of the relay 10.

[0106] Specifically, see Figure 3 and Figure 7 As shown, the spindle 331 includes a threaded section 33111 and a connecting section 33112. The threaded section 33111 is threadedly connected to the drive assembly 400. The connecting section 33112 is coaxially arranged with the threaded section 33111 and is connected to the insulating block 332. The outer diameter of the connecting section 33112 is larger than the outer diameter of the threaded section 33111.

[0107] To ensure the axial installation accuracy of the core structure 330, the mandrel 331 is provided with a threaded section 33111 and a connecting section 33112. The drive assembly 400 is equipped with a threaded through hole, and the length of the threaded section 33111 can be no less than the length of the threaded through hole. This design ensures sufficient contact area during connection, thereby enhancing the tightness and pull-out resistance of the connection. Especially under high loads or dynamic applications, this design significantly improves the reliability of the connection and reduces the risk of loosening due to vibration.

[0108] During the connection between the spindle 331 and the drive assembly 400, since the outer diameter of the connecting section 33112 is larger than that of the threaded section 33111, the connecting section 33112 can effectively limit the installation position between the spindle 331 and the drive assembly 400 after the threaded section 33111 is installed in place. This limiting mechanism not only provides an appropriate installation clearance but also ensures that the drive assembly 400 maintains a stable relative position with the spindle 331 during operation, thereby improving the engagement and disengagement performance of the relay 10.

[0109] In some embodiments, a flared intermediate section can be provided between the threaded section 33111 and the connecting section 33112. The purpose of this design is to make the connection between the threaded section 33111 and the connecting section 33112 smoother, thereby effectively reducing the internal stress generated in the mandrel 331 during operation. Specifically, the flared intermediate section has a certain bending characteristic. This shape can naturally disperse the pressure applied to the connection point when the two sections interact, avoiding sharp stress concentration. With the stress in the connection part being reasonably dispersed, the overall strength of the mandrel 331 is significantly improved, thereby extending its service life and reducing the probability of breakage due to material fatigue. Furthermore, the flared structure helps simplify the assembly process, reduces friction during connection, and greatly improves assembly efficiency, positively impacting the product's process level and automation level.

[0110] Meanwhile, a stepped structure can also be configured between the threaded section 33111 and the connecting section 33112. This design not only enables precise positioning but also improves connection stability. Specifically, the stepped structure allows for easy assembly during installation, achieving higher positioning accuracy within a smaller space. The advantage of this structure is its ability to effectively prevent displacement of the connection under high loads or dynamic operation, thus ensuring a reliable connection between the spindle 331 and the drive assembly 400. Under high-frequency operation, the stepped structure provides stronger resistance to detachment, ensuring the normal operation of the relay 10.

[0111] It's worth noting that the two structures—the flared intermediate section and the stepped structure—can be flexibly selected according to actual application needs, and can even be combined to improve overall performance. For example, combining these two structures can create a tiered flared transition section, with one part flared and the other stepped. This combination ensures smooth connection while achieving efficient component positioning, fully leveraging the respective technological advantages to adapt to various conditions.

[0112] In one embodiment, the drive assembly 400 is also provided with an adjustment hole 411 coaxial with the spindle 331, away from the elastic member 320.

[0113] This design makes maintaining and disassembling the drive assembly 400 more efficient and time-saving. Specifically, the adjustment hole 411 can be hexagonal in shape, which allows the drive assembly 400 to be disassembled using common hexagonal tools (such as wrenches or suitable hex screwdrivers), thus making it easier for users to maintain and repair the equipment.

[0114] Besides its internal hexagonal structure, the shape of the adjustment hole 411 is not limited to this. It can be designed in various other shapes, such as external hexagonal, circular, or elliptical, depending on actual usage requirements. This flexible design provides users with more choices, making the adjustment hole 411 compatible with different types of tools and adaptable to different working environments and maintenance needs. Among different shape designs, for example, an external hexagonal shape can be used to apply greater torque, a circular design may focus more on facilitating quick assembly and disassembly, while an elliptical shape helps to provide more flexible rotation space with the aid of tools. During implementation, selecting a suitable adjustment hole structure can effectively improve the disassembly and maintainability of the drive assembly 400.

[0115] Specifically, see Figures 3 to 9As shown, the frame structure 310 includes a connecting piece 311 and a fixing frame 312. The fixing frame 312 is connected to the connecting piece 311 and encloses the connecting piece 311 to form an active space. The connecting piece 311 is at least partially embedded in the insulating block 332, and the end of the elastic member 320 away from the moving electrode 200 is connected to the connecting piece 311.

[0116] In this embodiment, the connecting piece 311, the mandrel 331, and the insulating block 332 can be manufactured using an integral injection molding structure. The advantage of this manufacturing process is that it ensures a good fit between the various parts during molding. Furthermore, the integral injection molding structure helps reduce material costs and improve production efficiency, while also reducing waste generation.

[0117] During assembly, the fixing frame 312 forms a complete frame structure 310 by connecting with the connecting piece 311. At this point, the design of the fixing frame 312 not only provides strong support but also effectively restricts the movement of the moving electrode 200, preventing it from detaching from the operating space. This structural design effectively ensures the stability of the equipment, ensuring that the moving electrode 200 remains within the predetermined movement trajectory during operation, avoiding unnecessary damage caused by misoperation or external disturbances.

[0118] Specifically, the frame structure 310 can be made of metal. The advantage of this choice is that metal materials generally have superior mechanical properties, such as high strength, high rigidity and excellent wear resistance, which can provide reliable support and protection in environments with high loads and violent movements.

[0119] Furthermore, the metal material effectively improves the overall thermal conductivity of the product, facilitating heat dissipation through heat conduction during high-power operation and ensuring that components operate under normal conditions. Compared to plastics or other materials, the superior properties of metal can significantly extend the product's lifespan and reduce the failure rate.

[0120] See Figure 9 As shown, in one embodiment, the connecting piece 311 has a receiving hole 31121, and the spindle 331 passes through the receiving hole 31121 and is spaced apart from the inner wall of the receiving hole 31121.

[0121] Specifically, the purpose of this design is to ensure effective insulation between the mandrel 331 and the connecting piece 311 during the manufacturing and assembly of the structure, thereby improving the electrical safety and reliability of the overall structure.

[0122] In this embodiment, by spaced apart from the receiving hole 31121 and the mandrel 331, the manufacturing process of the connecting piece 311, the mandrel 331, and the insulating block 332 can be simplified during integral molding, avoiding complex post-assembly processes. During integral molding, the mandrel 331 can be accurately positioned within the receiving hole 31121 while maintaining an appropriate distance from the connecting piece 311. This effectively controls the injection of the insulating block 332, improving the insulation effect.

[0123] With this spacing arrangement, after molding, the insulation protection between the mandrel 331 and the connecting piece 311 is achieved by the insulating block 332. During injection molding, the insulating block 332 fills the gap area, forming a continuous insulating surface that prevents electrical contact between the mandrel 331 and the connecting piece 311. This design reduces the risk of short circuits, especially in high-frequency or high-current environments. The protection provided by the insulating block 332 effectively suppresses current leakage and signal interference, improving the reliability of the relay 10.

[0124] Furthermore, the connecting piece 311 has multiple through holes 31122, which are evenly arranged on the connecting piece 311 and embedded in the insulating block 332.

[0125] In this embodiment, by providing multiple through holes 31122 on the connecting piece 311, not only can the contact area between the connecting piece 311 and the insulating block 332 be increased, and the bonding strength between the two be improved, but the reliability and stability of the manufacturing process can also be further optimized.

[0126] In this configuration, when the connecting piece 311 and the insulating block 332 are integrally formed, the presence of the through hole 31122 allows the insulating block 332 to better surround and fix the connecting piece 311. This structural design not only increases the connection area but also helps reduce the risk of separation due to external impacts or vibrations, thereby improving the overall structural stability. It should be noted that the number of through holes 31122 can be multiple; for example, three, four, or more. The specific number should be considered and adjusted according to the actual application requirements.

[0127] In a preferred embodiment, a plurality of through holes 31122 are uniformly arranged along the circumference of the mandrel 331. The purpose of this design is to directly enhance the connection strength between the mandrel 331 and the insulating block 332. By uniformly distributing the through holes 31122 around the mandrel, stress can be effectively dispersed, improving the mechanical stability and durability of the connecting piece 311. This design is particularly important for applications in certain dynamic working environments; by optimizing the connection strength at each contact point, the risk of failure can be reduced, and the product's service life extended.

[0128] Specifically, see Figure 6 and Figure 7 As shown, the connecting piece 311 includes a plug-in portion 3111 and a connecting portion 3112 connected together. The connecting portion 3112 is at least partially embedded in the insulating block 332, and the plug-in portion 3111 is located on the outside of the connecting portion 3112. The fixing frame 312 has a connecting slot 3121, and the plug-in portion 3111 is plugged into the connecting slot 3121. This arrangement allows the plug-in portion 3111 to be easily plugged into the connecting slot 3121 of the fixing frame 312, thereby forming a compact and efficient connection structure.

[0129] In order to improve the connection strength between the connecting piece 311 and the fixing bracket 312, after the plug-in part 3111 is connected to the connecting slot 3121, the two can be fixed by means of riveting, welding or other methods, thereby improving the overall strength of the frame structure 310.

[0130] The structural design of the connector 3112 embedded in the insulating block 332 provides a larger contact area, effectively reducing separation caused by external forces. When the connector 3112 and the insulating block 332 are interlocked, a strong mechanical locking effect is formed, enhancing the stability of the component under dynamic conditions. The advantage of this structure is that it can withstand higher loads and improve overall seismic performance, which is particularly important for applications in vibration or shock environments.

[0131] In practical implementation, the length and diameter of the plug-in part 3111 can be adjusted according to specific design requirements. The specific values ​​should be selected based on a comprehensive consideration of the connection strength requirements and ease of operation. At the same time, the size and depth of the connecting slot 3121 should also match the plug-in part 3111 to ensure that the two can fit together firmly without slippage.

[0132] Furthermore, the structural design of the connector 312 could also incorporate elements such as guide slots or positioning rings to further enhance the smoothness and accuracy of the insertion process. These auxiliary structures not only improve connection efficiency but also effectively reduce damage and malfunctions caused by improper assembly, thereby improving the reliability and service life of the relay 10.

[0133] participate Figures 4 to 6 As shown, in one embodiment, the movable component 300 further includes a first magnetic yoke 340, which is connected to the moving electrode 200, and the end of the elastic member 320 away from the iron core structure 330 is connected to the first magnetic yoke 340; the movable component 300 further includes a second magnetic yoke 350, which is connected to the frame structure 310, and the second magnetic yoke 350 and the first magnetic yoke 340 are respectively located on opposite sides of the moving electrode 200.

[0134] Specifically, the first magnetic yoke 340 provides a combined magnetic field to the movable component 300. Through the interaction of current in the moving electrode 200, precise motion control is achieved, enabling the moving electrode 200 to respond quickly and stably to changes in external signals under the influence of the magnetic field. Since the first magnetic yoke 340 is connected to the elastic element 320, when the electromagnetic force generated by the current through the drive component 400 exceeds the restoring force of the elastic element 320, the moving electrode 200 will move in a predetermined direction; once the current stops or decreases, the elastic element 320 will push the moving electrode 200 back to its original position, generating high repeatability and stability.

[0135] The second yoke 350, symmetrically connected to the frame structure 310 with the first yoke 340, ensures the system's balance and structural strength, thereby enhancing the ability of the entire moving component 300 to withstand external forces during operation. The second yoke 350 works in conjunction with the first yoke 340 to provide a stronger magnetic field, thus enhancing the movement capability of the moving electrode 200. Especially under high load or high frequency operation, the cooperation of the first yoke 340 and the second yoke 350 not only improves efficiency but also effectively prevents overheating or mechanical wear of the relay 10.

[0136] In practical implementation, the advantage of this design is that the symmetrical layout of the magnetic yokes on both sides can effectively balance the forces on the equipment, while increasing the stability of the entire magnetic circuit. This structure avoids the risk of mechanical failure that may be caused by excessive force on one side.

[0137] Furthermore, by configuring the first magnetic yoke 340 and the second magnetic yoke 350 to work together, the moving electrode 200 will be magnetized and attract a certain amount of force when a large current passes through it. This design effectively ensures that the moving electrode 200 remains in close contact with the stationary electrode 500 under high current conditions, thereby improving the reliability of the relay 10.

[0138] Specifically, the first magnetic yoke 340 includes a supporting portion 341 and a bending portion 342. The bending portion 342 is connected to the edge of the supporting portion 341 and bends toward the moving electrode 200. The supporting portion 341 is connected to the elastic member 320.

[0139] In one embodiment, the first magnetic yoke 340 adopts a U-shaped structure. This design aims to ensure good magnetic field transmission by improving the coupling efficiency between the magnetic yoke and the moving electrode 200. The moving electrode 200 is riveted and embedded into the U-shaped opening of the first magnetic yoke 340. This fixing method makes the combined structure of the two very compact, effectively reducing the relative displacement that may occur during movement, thereby improving the stability and response speed of the device. When the moving electrode 200 moves under the action of electromagnetic force, the U-shaped structure can keep the moving electrode 200 at the center of the magnetic yoke to the greatest extent, making the movement trajectory more accurate and effectively improving the overall working efficiency.

[0140] Of course, in some other embodiments, the first magnetic yoke 340 may also adopt an L-shaped structure. The choice of this structure depends on the space constraints and performance requirements of the specific application. The L-shaped design allows for more flexible arrangement, especially in space-constrained situations, effectively integrating other parts of the device while achieving the necessary electromagnetic characteristics. During the design process, the stress distribution that may occur during use of the L-shaped physical structure and the movement trajectory of the moving electrode 200 must be fully considered to ensure its reliability.

[0141] To further enhance the connection strength between the moving electrode 200 and the first magnetic yoke 340, various connection methods can be employed, such as welding, bonding, and snap-fitting. Welding provides a durable and stable connection, suitable for applications requiring high strength and good conductivity; bonding offers advantages such as easy assembly and no heat-affected zone, making it suitable for applications requiring lower mechanical strength. Furthermore, snap-fitting provides excellent ease of disassembly and maintenance.

[0142] Furthermore, the first magnetic yoke 340 is provided with a positioning part 343, and the end of the elastic member 320 facing the first magnetic yoke 340 is connected to the positioning part 343.

[0143] This design enhances the installation accuracy between the elastic element 320 and the first magnetic yoke 340. Specifically, the introduction of the positioning part 343 effectively and precisely positions the connection between the elastic element 320 and the first magnetic yoke 340, thereby reducing possible relative displacement and ensuring that the elastic element 320 maintains its original functional characteristics during movement, further improving the reliability of the entire relay 10.

[0144] Specifically, the elastic element 320 is typically used to provide the necessary elastic restoring force, enabling the moving electrode 200 to quickly return to its initial position after being subjected to electromagnetic forces. By providing a positioning portion 343 between the elastic element 320 and the first magnetic yoke 340, the geometry of their connection can be effectively improved, avoiding poor contact or failure caused by vibration or dynamic loads. This design, by optimizing the internal and external mechanical environment, ensures that the performance of the moving electrode 200 is always at its best under various operating conditions.

[0145] In practical implementation, the positioning part 343 can adopt different materials and structural forms, such as bosses, grooves, or other mechanically interlocking shapes. This design choice brings additional benefits, such as allowing for more flexibility in the optimized design of the elastic element 320 by adjusting the geometry and material properties of the positioning part 343 to meet specific operational requirements. Furthermore, when the shape of the positioning part 343 is optimized, the wear and tear on the elastic element 320 during operation can be effectively reduced, improving durability and thus reducing maintenance frequency and costs.

[0146] In one embodiment, the number of positioning parts 343 is multiple, and the multiple positioning parts 343 are evenly arranged along the circumferential direction of the core structure 330, and the multiple positioning parts 343 are arranged around the elastic member 320. This design enables the multiple positioning parts 343 to form an effective surrounding structure around the elastic member 320, thereby achieving precise positioning of the elastic member 320.

[0147] By uniformly and symmetrically arranging multiple positioning parts 343 within a 360-degree range, not only can the external forces borne by the elastic element 320 be balanced, but the elastic element 320 can also be effectively prevented from shifting or displacing during its operation, ensuring that it always remains in the ideal working position. The key advantage of this design is that it provides excellent mechanical stability, enabling the elastic element 320 to maintain its performance during long-term use and avoiding wear or damage caused by displacement.

[0148] In practical implementation, the bottom of the first magnetic yoke 340 is designed with four circular protrusions. These protrusions are intended to accommodate different types of elastic elements 320. For example, elastic elements 320 such as coil springs can be easily placed within the enclosure structure formed by these four positioning parts 343. In this case, this structural design not only precisely positions the radial position of the elastic element 320 but also provides sufficient support, making it less prone to deformation or failure when subjected to external forces. The circular protrusions effectively disperse the external forces applied to the elastic element 320, avoiding localized stress concentration, thereby improving the reliability and durability of the elastic element 320 during operation.

[0149] In other embodiments, the number of positioning parts 343 can be flexibly adjusted, including three, four, or more. The specific number can be selected according to design requirements, and this is not a unique limitation during implementation. The technical advantage of setting multiple positioning parts 343 is that it increases the system's fault tolerance and adaptability. When the number or type of elastic element 320 changes, by increasing or decreasing the number of positioning parts 343, it can be ensured that it maintains a stable positioning effect under different working conditions. This flexible design choice can interpret the specific requirements of elastic element 320 under different working conditions, thereby achieving optimization of the overall structure.

[0150] See Figure 6 As shown, in one embodiment, the edge of the second magnetic yoke 350 is provided with a clearance slot 351, and the opening of the clearance slot 351 faces the stationary electrode 500.

[0151] In this embodiment, the second magnetic yoke 350 adopts a design with two symmetrical clearance slots 351, forming an hourglass-shaped structure. This hourglass-shaped structure not only ensures sufficient operating space for the stationary electrode 500, but also reduces potential interference between the two during operation. Especially when the stationary electrode 500 moves frequently during operation, the clearance slots 351 effectively reduce the risk of mechanical collisions, thereby improving the operational reliability and safety of the equipment.

[0152] Specifically, the stationary electrode 500 can be located at the opening of this hourglass-shaped structure, which provides greater flexibility and space for the movement of the stationary electrode 500. On the one hand, this design allows the stationary electrode 500 to reciprocate freely without being obstructed by the edge of the second magnetic yoke 350 due to its shape or movement trajectory; on the other hand, it avoids failures caused by frequent pneumatic or electric collisions, extending the service life and reliability of the stationary electrode 500.

[0153] In other embodiments, the second magnetic yoke 350 can also be designed and configured differently according to application requirements. For example, the number of clearance slots 351 can be one, two, or more, and is not limited to one. When multiple clearance slots 351 are used, they can be rationally arranged according to actual space and mechanical requirements, thereby further improving the adaptability and flexibility of the static electrode 500. Similarly, the size and protective structure of the clearance slots 351 can be adjusted according to specific design requirements to ensure the normal operation of the system in different working environments.

[0154] Furthermore, the frame structure 310 has a riveting position 3122 on the side facing the activity space, and the second magnetic yoke 350 has a riveting protrusion 352. The second magnetic yoke 350 is riveted and fixed to the riveting position 3122 through the riveting protrusion 352.

[0155] Specifically, the fixing frame 312 adopts a U-shaped thin-plate structure, possessing good strength and stability, while the riveting position 3122 on its upper surface provides important mechanical support for the entire connection. During the connection process, the riveting protrusion 352 of the second magnetic yoke 350 is riveted to the riveting position 3122 of the fixing frame 312, ensuring a tight fit between the two. This connection method not only improves the convenience of assembly but also achieves high connection strength, ensuring that the riveted parts will not easily loosen or shift when subjected to external forces during operation. This connection method using riveting is compact in structure, suitable for design environments with limited space, and possesses excellent seismic resistance and stability.

[0156] It is important to note that the design of the riveting position 3122 is flexible and can be either a through hole or a blind hole; there is no single limitation. A through hole design simplifies the riveting operation, allowing the second magnetic yoke 350 to be installed and removed from both sides, facilitating maintenance and replacement. A blind hole design, on the other hand, improves the overall aesthetics and prevents contaminants from entering the structure in certain applications, enhancing the product's sealing performance. This flexibility allows the equipment to better adapt to various needs in different industries and application scenarios.

[0157] By employing a riveted fixing structure, the connection between the frame structure 310 and the second magnetic yoke 350 is not only easy to implement during manufacturing but also allows for easy disassembly during subsequent maintenance, reducing maintenance complexity. Simultaneously, the riveted structure effectively disperses external forces, improving overall consistency and stability, and ensuring reliable operation of the equipment under high load or high vibration environments. This effectively extends the service life of the overall device and, to some extent, reduces the failure rate caused by fatigue at the connection points.

[0158] Specifically, see Figure 4 and Figure 5 As shown, the moving electrode 200 has a plate-like structure, and the stationary electrode 500 is at least partially located outside the active space. The moving electrode 200 is at least partially located outside the active space and is used to contact the stationary electrode 500.

[0159] First, the plate-like structure effectively reduces the volume of the moving electrode 200. Combining the moving electrode 200 with the movable component 300 ensures a more compact overall structure. This compact design not only saves space, making the relay 10 more flexible during installation and use, but also improves the mechanical stability of the relay 10, helping to reduce the impact of vibrations caused by external environment or equipment operation.

[0160] Secondly, the plate-like structure of the moving electrode 200 provides it with greater operational space. As the moving electrode 200 extends outward from this space, it facilitates contact with the stationary electrode 500. Specifically, when the moving electrode 200 extends outward, it can achieve various functions through contact with different stationary electrodes 500, such as establishing more complex electrical connections or further current conduction paths. This is particularly important for multi-power supply or multi-mode operating systems, as the switching of current between different stationary electrodes 500 enables the diversification of equipment functions and meets the needs of different operating conditions.

[0161] Furthermore, the design of the moving electrode 200 ensures uniform current conduction within it. This is because the plate-like structure of the moving electrode 200 effectively avoids current concentration caused by irregular shapes, thereby reducing heat generation and energy loss during current flow. This characteristic is extremely important, especially in high-frequency or high-power applications, where current uniformity can significantly improve equipment performance and safety, and extend the lifespan of the moving electrode 200.

[0162] It should be noted that the plate-like structure of the moving electrode 200 can be made of different materials and thicknesses in practical applications to adapt to different electrical characteristics and operating conditions. For example, the material of the moving electrode 200 can be a conductive metal or a composite material with high conductivity, while its thickness can be designed according to actual conditions to ensure that the moving electrode 200 has good conductivity.

[0163] Further, see Figure 4 As shown, the outer side of the moving electrode 200 is provided with an arc-shaped edge 210.

[0164] Specifically, the main advantage of the curved edge 210 is its ability to effectively reduce arcing that may occur when in contact with the stationary electrode 500. In high-voltage and high-current operating environments, arcs can easily form between the moving and stationary electrodes, damaging them and shortening their lifespan. If the edge of the moving electrode 200 were straight, current might concentrate in specific areas, increasing localized heating and material aging. In contrast, the curved edge 210 allows for a more uniform current distribution, which not only helps reduce the likelihood of arcing but also improves electrode durability.

[0165] Furthermore, the arc-shaped edge 210 design makes current conduction more stable under high-frequency current. The arc design effectively disperses the electric field intensity at the contact point, thereby reducing abnormal current fluctuations caused by uneven electric field. This uniform current distribution and streamlined edge structure enable the moving electrode 200 to maintain good performance even in frequent working environments, effectively extending its service life and durability.

[0166] Furthermore, the moving electrode 200 is not limited to the semi-circular shape at both ends in its design. The shape of the moving electrode can be extended to other shapes, such as arc, trapezoid, or other streamlined structures, according to different application requirements. Different edge designs can bring different electrical characteristics and mechanical strength, which helps to further optimize the application performance of the moving electrode 200 in specific environments.

[0167] See Figure 3As shown, in one embodiment, the drive assembly 400 includes an iron core 410 and an electromagnet. The iron core 410 is movably disposed relative to the mounting member 100, and the electromagnet is used to drive the iron core 410 to move relative to the mounting member 100, so as to drive the moving electrode 200 to contact or separate from the stationary electrode 500.

[0168] Specifically, the movable design of the iron core 410 allows it to move freely along a predetermined track or path, a structure that fully utilizes the inductive force of the electromagnet. When the electromagnet is energized, it generates a magnetic field, attracting or repelling the iron core 410. The movement range is adjusted according to the direction and magnitude of the current, controlling the opening and closing state of the moving electrode 200. This functional design provides the necessary driving force for the connection and disconnection between the moving electrode 200 and the stationary electrode 500, ensuring the functional switching of the relay 10 under different operating states.

[0169] In practical applications, the electromagnet can be either a DC electromagnet or an AC electromagnet, and the specific choice can be adjusted according to the system requirements. DC electromagnets typically have a faster response speed and higher control precision, making them suitable for applications requiring rapid response; while AC electromagnets exhibit better stability and reliability during long-term operation, making them suitable for environments with continuous and frequent operation. In one embodiment, the electromagnet can be a coil, and the coil is arranged around the iron core 410. By energizing the coil, a magnetic field is generated to drive the iron core 410 to move. Therefore, depending on the specific application scenario, introducing different types of electromagnets helps optimize the overall performance of the drive assembly 400.

[0170] This design of the drive assembly 400 achieves efficient current conduction. When the electromagnet drives the iron core 410 to move, the moving electrode 200 changes its relative position accordingly, ensuring absolute contact or effective separation with the stationary electrode 500 through precisely controlled contact interference. This allows the entire system to flexibly respond to different electrical requirements, providing great convenience, especially in situations such as adjusting current, controlling voltage, or changing operating modes.

[0171] It is worth noting that the design of the drive assembly 400 is not limited to the combination of the iron core 410 and the electromagnet; its structure can be further expanded to accommodate various driving methods. For example, servo motors, stepper motors, or pneumatic devices can be introduced. By combining different driving methods, the operational flexibility and adaptability between the moving electrode 200 and the stationary electrode 500 can be broadened. This will significantly improve the operational performance and reliability of the equipment under different working conditions, and enhance the stability of the system under complex conditions such as high load and high frequency.

[0172] Further, see Figure 3As shown, the drive assembly 400 also includes a limiting post 420, which is connected to the mounting component 100 and has a guide hole 421. The core structure 330 slides in cooperation with the guide hole 421.

[0173] By setting the limiting post 420 to cooperate with the iron core structure 330, the movement of the iron core structure 330 can be effectively guided. The design of the guide hole 421 ensures the linear movement of the iron core structure 330 during operation, avoiding possible deviation or swaying during movement. This sliding fit not only improves the operating accuracy of the drive components, but also reduces wear caused by improper movement, thereby extending the service life of the overall device.

[0174] Furthermore, the drive assembly 400 enhances operational safety by simultaneously establishing a cooperative relationship between the limiting post 420 and the iron core 410. When the iron core 410 moves to its limit position under the drive of the electromagnet, it contacts the limiting post 420, thus limiting its movement. This limiting structure effectively prevents excessive displacement of the iron core 410, avoiding potential mechanical damage or malfunction of the electromagnetic equipment due to excessive displacement. The presence of the limiting post 420 provides a mechanical protection measure for the entire drive assembly, enabling the equipment to better maintain stability and safety under high load or high frequency operation.

[0175] Specifically, the design of the limiting post 420 can take various forms, such as columnar or block structures, and is not limited to a single form. This diverse construction can adapt to different installation requirements and space constraints, thus better suiting specific application scenarios. Furthermore, by adjusting the size, shape, and position of the guide hole 421, the range of motion of the core structure 330 can be customized to meet the performance requirements of users under different working conditions.

[0176] Guided by the limiting post 420 and driven by the electromagnet, the iron core structure 330 enables faster and more accurate contact and separation between the moving electrode 200 and the stationary electrode 500, improving the response speed and flexibility of the equipment during operation. Overall, the design of the limiting post 420 provides reliable guidance and limiting functions for the drive assembly 400, ensuring the safety and efficiency of the entire relay 10 during operation.

[0177] Specifically, the mounting component 100 has a fixing hole 110, and the limiting post 420 is at least partially inserted into the fixing hole 110.

[0178] By inserting the limiting post 420 into the fixing hole 110, a tight assembly structure can be achieved between the limiting post 420 and the mounting component 100. This assembly not only reduces the volume of components and improves assembly efficiency, but also reduces the overall weight of the device, thereby improving the responsiveness and accuracy of the equipment during use. Furthermore, this combination also makes the limiting post 420 more stable during operation, reducing displacement caused by external forces or vibrations, and ensuring the sliding stability of the core structure 330 within the guide hole 421.

[0179] It is worth noting that the design of the fixing hole 110 can be adjusted to a certain extent. For example, its shape can be circular, square, or other polygonal to accommodate different shapes of the limiting post 420. This allows users to select the appropriate shape and size of the fixing hole 110 according to actual engineering needs, improving the flexibility and adaptability of the equipment. At the same time, the size of the fixing hole 110 can be optimized according to actual load and operating conditions, ensuring that the limiting post 420 can be securely embedded within the fixing hole 110, further enhancing the durability and reliability of the entire device.

[0180] Furthermore, from an installation and commissioning perspective, the design of the fixing hole 110 makes the installation process of the limiting post 420 more convenient. Operators can quickly assemble and disassemble the component by inserting or removing the limiting post 420, reducing production and maintenance costs and improving work efficiency. This design is particularly suitable for equipment that requires frequent maintenance or replacement, ensuring convenience during the maintenance process.

[0181] In one embodiment, the drive assembly 400 includes a housing 430, which is connected to the mounting member 100 to form a complete drive structure. Furthermore, the iron core 410 is effectively housed within the housing 430, supporting its free movement during operation. This design not only enables the movement of the iron core 410 but also provides stability to the overall structure.

[0182] By fitting the housing 430 with the iron core 410, the drive assembly 400 achieves excellent dust protection. The advantage of this design is that the housing 430 effectively isolates dust and debris from the external environment, preventing them from entering the drive assembly and avoiding friction or obstruction of the iron core 410's movement caused by contaminants. This dustproof design greatly improves the reliability of the relay 10 in harsh environments, ensuring stable operation under various working conditions, thereby enhancing the durability and service life of the relay 10.

[0183] In other embodiments, the limiting post 420 may also be housed within the housing 430. This provides additional protection for the limiting post 420 and also enhances the overall structural integrity of the drive assembly 400. The protection of the limiting post 420 effectively reduces the risk of wear and damage, ensuring stable performance during long-term use. By integrating the limiting post 420 with the housing 430, users can also reduce the maintenance requirements of the device and improve user convenience.

[0184] Specifically, the housing 430 can be designed using various materials and sizes to adapt to different application scenarios and user needs. Common materials may include plastics, metals, or composite materials, and users can choose the appropriate housing material based on the required strength, corrosion resistance, and protection level of the relay 10. The dimensions of the housing 430 can also be adjusted to accommodate different sizes of the iron core 410 and the limiting post 420, thereby ensuring compatibility and sealing during assembly.
