Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to relays. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current, thus playing roles in automatic adjustment, safety protection, and circuit switching. It is used in household appliances, automobiles, industrial control, power systems, and communication devices.

[0003] A high-voltage DC relay is a type of relay that includes a coil, a moving iron core, a stationary iron core, a drive assembly, and a yoke assembly. Specifically, when the coil is energized, the moving iron core becomes an electromagnet, quickly attracting the yoke assembly or the stationary iron core, thus driving the drive assembly. When the coil is de-energized, the moving iron core separates from the yoke assembly or the stationary iron core, the drive assembly collides with the yoke assembly, and the entire movement stops.

[0004] However, during the startup process, the attraction between the moving iron core and the yoke assembly or the stationary iron core generates significant noise. Similarly, during the shutdown process, the collision between the drive assembly and the yoke assembly also generates significant noise, resulting in considerable noise during the operation of the relay.

[0048] The first direction intersects perpendicularly with the third direction.

[0049] In some embodiments, the second noise reduction component is a one-piece molded structure; and / or

[0050] The second noise reduction component is an elastic component.

[0051] The aforementioned relay is disposed within a housing assembly. The relay includes a relay body and a first noise reduction element. The relay body is located within the housing assembly and includes a yoke assembly. At least a portion of the first noise reduction element is disposed between the yoke assembly and the housing assembly.

[0052] The relay of this application, when generating significant noise during startup and shutdown, needs to transmit this noise to the outside through the housing assembly. By providing a first noise reduction component between the yoke assembly and the housing assembly, the propagation of noise generated when the drive assembly collides with the yoke assembly can be reduced, thereby reducing the noise transmitted to the outside of the relay during use.

[0053] Furthermore, since the first noise reduction component is fixedly connected to at least one of the yoke assembly and the housing assembly, it can be ensured that the first noise reduction component is always in a position that can effectively reduce noise during use, and will not be displaced due to vibration, shaking or other external forces, thereby continuously and stably performing the noise reduction function.

[0054] Furthermore, since the side of the first abutting part facing the first housing wall abuts against the side of the first yoke body facing the second housing wall, and the side of the second abutting part facing the second housing wall abuts against the side of the first yoke body facing the first housing wall, two opposing forces can be applied to the first yoke body along the first direction through the first abutting part and the second abutting part. This can further restrict the movement of the first noise reduction component along the first direction, thereby further improving the tightness of the connection between the first noise reduction component and the first yoke body, and ultimately improving the stability between the first noise reduction component and the second housing and yoke assembly, thus improving the performance of the relay.

[0055] Furthermore, since one of the housing assembly and the yoke assembly is connected to the first noise-reducing component, and the other has a positioning groove, with a portion of the first noise-reducing component located within the positioning groove, it ensures that the first noise-reducing component can be precisely placed in the intended position, guaranteeing its effective blocking and absorption of noise generated during relay operation. Additionally, the positioning groove restricts the movement and shaking of the first noise-reducing component during relay operation, improving its installation stability and allowing it to better perform its noise-reducing function. Simultaneously, this connection method allows for a tighter fit between the first noise-reducing component and the housing assembly and yoke assembly, further enhancing the stability of the entire relay structure.

[0056] Specifically, a portion of the first noise reduction component is located in the positioning groove, which ensures that the first noise reduction component does not wobble. This, in turn, ensures that the yoke assembly on the side of the first noise reduction component away from the positioning groove does not wobble, ultimately ensuring that the relay body does not wobble relative to the housing assembly. Furthermore, this improves the stability between the main stationary contact on the relay body and the client, preventing wobble between the main stationary contact and the client, thereby reducing the probability of cracking between the main stationary contact and the ceramic cover due to wobble.

[0057] Furthermore, the relay also includes a second noise reduction element, which is disposed within the housing assembly, with at least a portion of the second noise reduction element located between the second yoke body and the inner wall of the housing assembly. When the drive assembly impacts the second yoke body, generating noise, the second noise reduction element can reduce the propagation of the noise, thereby reducing the noise transmitted to the outside of the relay during use and meeting user requirements. Simultaneously, since the second yoke body is closer to the noise source within the relay, placing the second noise reduction element between the second yoke body and the housing assembly allows it to be closer to the noise source, further improving its noise reduction effect.

[0058] Furthermore, since the first noise reduction component is fixedly connected to at least one of the yoke assembly and the housing assembly, and the second noise reduction component abuts against the inner wall of the second yoke body and the housing assembly, it can be understood that the direction in which the first noise reduction component is fixedly connected to at least one of the yoke assembly and the housing assembly is different from the direction in which the second noise reduction component abuts against the inner wall of the second yoke body and the housing assembly. Therefore, through the cooperative action of the first and second noise reduction components, the fit between the first and second noise reduction components and the housing assembly and the yoke assembly in all directions is made tighter, further enhancing the stability of the entire relay structure in all directions. Simultaneously, since the first and second noise reduction components are located at different positions on the yoke assembly and the housing assembly, the noise reduction effect in all directions can be improved.

[0078] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0079] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0080] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0081] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0082] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0083] See Figures 1-5 As shown. One embodiment of this application provides a relay 10 for installation in a housing assembly 1. The relay 10 includes a relay body 2 and a first noise reduction element 3. The relay body 2 is disposed within the housing assembly 1 and includes a yoke assembly 21. At least a portion of the first noise reduction element 3 is disposed between the yoke assembly 21 and the housing assembly 1.

[0084] It should be noted that the housing assembly 1 can serve as the frame structure of the relay 10, in which case the housing assembly 1 is a structure within the relay 10. Alternatively, the housing assembly 1 can serve as an external structure housing the relay 10, in which case the housing assembly 1 is not a structure within the relay 10. For example, the housing assembly 1 can be a structure within a battery pack, with the relay housed within the housing assembly 1 of the battery pack.

[0085] On one hand, the housing assembly 1 is used to support and fix the relay body 2 and the first noise reduction component 3 in the relay 10, thereby ensuring the normal operation of the relay body 2 and the first noise reduction component 3. On the other hand, the housing assembly 1 is used to protect the relay body 2 and the first noise reduction component 3, preventing external structures from damaging the relay body 2 and the first noise reduction component 3, thereby further ensuring the normal operation of the relay 10.

[0086] It should be further explained that the relay body 2 also includes a coil. The coil in the relay body 2 is the key component for generating a magnetic field. When current flows through it, a magnetic field is generated around it, which attracts the iron core and controls the switching state of the contacts. The yoke assembly 21 in the relay 10 can guide and concentrate the magnetic field generated by the coil, making the magnetic field more concentrated in a specific area, thereby enhancing the strength of the magnetic field and improving the electromagnetic conversion efficiency.

[0087] Because a first noise reduction component 3 is provided between the yoke assembly 21 and the housing assembly 1, when the drive assembly and the yoke assembly 21 collide and generate noise, the propagation of noise can be reduced by the first noise reduction component 3. This can reduce the noise transmitted from the relay 10 to the outside of the relay 10 during use, thereby meeting the user's usage needs.

[0088] In some embodiments, the first noise reduction element 3 is fixedly connected to at least one of the yoke assembly 21 and the housing assembly 1.

[0089] Thus, since the relay 10 may vibrate or be affected by external environmental factors during operation, fixing the first noise reduction component 3 to at least one of the yoke assembly 21 and the housing assembly 1 ensures that the first noise reduction component 3 is always in a position that effectively reduces noise during use, and will not shift due to vibration, shaking, or other external forces, thereby continuously and stably performing its noise reduction function. Simultaneously, fixing the first noise reduction component 3 to at least one of the yoke assembly 21 and the housing assembly 1 ensures close contact between the first noise reduction component 3 and the yoke assembly 21 or the housing assembly 1, reducing gaps and leakage paths for noise propagation, thereby improving the overall noise reduction effect. Furthermore, fixing the first noise reduction component 3 to at least one of the yoke assembly 21 and the housing assembly 1 can, to a certain extent, enhance the structural stability between the yoke assembly 21 and the housing assembly 1, thereby improving the overall reliability of the relay 10 structure.

[0090] In some embodiments, the relay 10 includes a housing assembly 1, which includes a first housing wall 1a and a second housing wall 1b disposed opposite each other along a first direction, and the relay body 2 is located between the first housing wall 1a and the second housing wall 1b. The yoke assembly 21 includes a first yoke body 211 and an extension 212 connected together. The first yoke body 211 is located at the end of the relay body 2 along the first direction and is disposed close to the first housing wall 1a. The extension 212 is disposed on the side of the first yoke body 211 facing the second housing wall 1b. At least a portion of the first noise reduction member 3 is disposed between the first yoke body 211 and the first housing wall 1a, and the first noise reduction member 3 is fixedly connected to the first yoke body 211.

[0091] It should be noted that the first direction is Figure 1 and Figure 2 The X direction in the equation.

[0092] It is understood that the first yoke body 211 is located at the end of the relay body 2 along the first direction and is disposed towards the first housing wall 1a. The extension 212 is disposed on the side of the first yoke body 211 facing the second housing wall 1b. For example, the first yoke body 211 and the extension 212 can be an integral structure, or the first yoke body 211 and the extension 212 can be a "U-shaped" structure. Of course, the first yoke body 211 and the extension 212 can also be a separate structure, or the first yoke body 211 and the extension 212 can be other shapes. Here, the connection method and specific shape of the first yoke body 211 and the extension 212 are not limited or described in detail.

[0093] Thus, the first shell wall 1a and the second shell wall 1b, which are arranged opposite each other along the first direction in the housing assembly 1, provide a stable external protective frame for the relay body 2. Placing the relay body 2 between the first shell wall 1a and the second shell wall 1b can effectively prevent external dust, moisture, external forces, etc. from damaging the relay body 2, ensuring that it works in a relatively stable and safe environment.

[0094] Furthermore, at least a portion of the first noise reduction component 3 is disposed between the first yoke body 211 and the first shell wall 1a, and is fixedly connected to the first yoke body 211. This allows the first noise reduction component 3 to precisely block and absorb the noise generated when the first yoke body 211 is working. During the start-up and stop of the relay 10, when significant noise is generated within the relay 10, the first noise reduction component 3, being tightly connected to the first yoke body 211 and located between the noise source and the first shell wall 1a, can minimize the propagation of noise through the first shell wall 1a, thereby effectively reducing the noise during relay 10 operation and improving the quietness performance of the relay 10. In addition, the fixed connection ensures that the first noise reduction component 3 will not shift due to vibration or other external forces during the operation of the relay 10, and can continuously and stably perform its noise reduction function.

[0095] In some embodiments, the first yoke body 211 and the extension 212 together enclose a U-shaped structure.

[0096] It should be noted that the relay body 2 also includes a coil.

[0097] Thus, the extension 212 of the U-shaped structure is located on the outer periphery of the coil, which can wrap around the coil and together with the first yoke body 211 form a semi-closed frame that wraps around the shape of the coil, making full use of the internal space of the housing assembly 1 and making the layout of each component more compact.

[0098] In some embodiments, the first noise reduction element 3 is disposed entirely on the side of the first yoke body 211 facing the first shell wall 1a.

[0099] Thus, since the first noise reduction component 3 is entirely located on the side of the first yoke body 211 facing the first shell wall 1a, in the process of connecting the first noise reduction component 3 and the first yoke body 211, it is only necessary to connect the first noise reduction component 3 and the side of the first yoke body 211 facing the first shell wall 1a. This makes it convenient for installers to install the first noise reduction component 3 and the yoke assembly 21, thereby improving the processing and production efficiency of the relay 10.

[0100] In some embodiments, the first yoke body 211 is provided with a through hole, which extends through the first yoke body 211 in a first direction; a portion of the first noise reduction component 3 is provided on the side of the first yoke body 211 facing the first shell wall 1a; and another portion of the first noise reduction component 3 passes through the through hole.

[0101] Thus, since a portion of the first noise-reducing component 3 is located on the side of the first yoke body 211 facing the first shell wall 1a, this portion of the first noise-reducing component 3 only needs to be connected to the side of the first yoke body 211 facing the first shell wall 1a to achieve connection with the first yoke body 211, thereby facilitating the connection between the first noise-reducing component 3 and the first yoke body 211. Simultaneously, since another portion of the first noise-reducing component 3 passes through the through hole, on the one hand, the tightness of the connection between the first noise-reducing component 3 and the first yoke body 211 can be improved, thereby enhancing the stability of the connection between the first noise-reducing component 3 and the yoke assembly 21. On the other hand, since the first noise-reducing component 3 passes through the through hole, when the position of the through hole is pre-set, the position of the first noise-reducing component 3 can be restricted through the through hole, ensuring that the first noise-reducing component 3 is placed in a suitable position, thereby improving the performance of the first noise-reducing component 3.

[0102] In some embodiments, see Figure 5 and Figure 6As shown, the first noise reduction component 3 includes a noise reduction component body 31, a first abutting portion 32, and a second abutting portion 33. The noise reduction component body 31 passes through the through hole; the first abutting portion 32 is located on the side of the noise reduction component body 31 facing the second shell wall 1b, and the side of the first abutting portion 32 facing the first shell wall 1a abuts against the side of the first yoke body 211 facing the second shell wall 1b; the second abutting portion 33 is located on the side of the noise reduction component body 31 facing the first shell wall 1a, and the side of the second abutting portion 33 facing the second shell wall 1b abuts against the side of the first yoke body 211 facing the first shell wall 1a; along the first direction, the projection of the through hole on the first shell wall 1a is located within the projection of the first abutting portion 32 on the first shell wall 1a, and the projection of the through hole on the first shell wall 1a is located within the projection of the second abutting portion 33 on the first shell wall 1a.

[0103] Thus, since the first abutting part 32 abuts against the side of the first housing wall 1a facing the side of the first yoke body 211 facing the second housing wall 1b, and the second abutting part 33 abuts against the side of the second housing wall 1b facing the side of the first yoke body 211 facing the first housing wall 1a, the first abutting part 32 and the second abutting part 33 can apply two opposite forces to the first yoke body 211 along the first direction, thereby further restricting the movement of the first noise reduction component 3 along the first direction, thereby further improving the tightness of the connection between the first noise reduction component 3 and the first yoke body 211, and ultimately improving the stability between the first noise reduction component 3 and the second housing 12 and the yoke assembly 21, and improving the performance of the relay 10.

[0104] Furthermore, since the projection of the through hole on the first housing wall 1a is located within the projection of the first abutting part 32 on the first housing wall 1a along the first direction, and the projection of the through hole on the first housing wall 1a is located within the projection of the second abutting part 33 on the first housing wall 1a, separation between the first noise reduction member 3 and the first yoke body 211 can be avoided, thereby improving the overall reliability of the relay 10.

[0105] In some embodiments, at least a portion of the surface of the first abutment portion 32 is configured as a guide surface 32a, and the cross-sectional area of ​​the first abutment portion 32 at the guide surface 32a gradually decreases from the second abutment portion 33 to the first abutment portion 32 in a direction perpendicular to the first direction.

[0106] Thus, when the first noise-reducing component 3 is installed onto the first yoke body 211, the guide surface 32a can act as a guide. Because the cross-sectional area of ​​the first abutment portion 32 at the guide surface 32 gradually decreases from the second abutment portion 33 to the first abutment portion 32 along a direction perpendicular to the first direction, the first abutment portion 32 is wider at the end near the second abutment portion 33 and gradually narrows at the end away from the second abutment portion 33. This makes it easier to align and insert the first abutment portion 32 into the corresponding position during installation, allowing installers to more easily connect the first noise-reducing component 3 to the first yoke body 211, reducing obstacles during installation and improving installation efficiency.

[0107] Furthermore, once the first noise-reducing component 3 is installed, the design of the guide surface 32a allows for a tighter contact between the first abutment portion 32 and the first yoke body 211. As the first abutment portion 32 is gradually inserted, its contact area with the first yoke body 211 gradually increases, thereby increasing the friction and adhesion between the two. This further improves the stability of the connection between the first noise-reducing component 3 and the first yoke body 211, ensuring that the first noise-reducing component 3 will not easily loosen or shift due to vibration or other external forces during the operation of the relay 10, and can continuously and stably perform its noise-reducing function.

[0108] In some embodiments, one of the housing assembly 1 and the yoke assembly 21 is connected to the first noise reduction member 3, and the other is provided with a positioning groove 1d, with a portion of the first noise reduction member 3 located in the positioning groove 1d.

[0109] Thus, the positioning groove 1d provides a precise installation position for the first noise reduction component 3, ensuring that it can be accurately placed in the expected position and effectively block and absorb the noise generated by the relay 10 during operation. Furthermore, the fact that part of the first noise reduction component 3 is located within the positioning groove 1d restricts its movement and shaking during the operation of the relay 10, improving the stability of its installation and allowing it to better perform its noise reduction function. Simultaneously, this connection method allows for a tighter fit between the first noise reduction component 3 and the housing assembly 1 and the yoke assembly 21, further enhancing the stability of the entire relay 10 structure.

[0110] Specifically, the movement of the first noise reduction component 3 in the first, second, and third directions can be restricted, which can ensure that the product is fixed in the housing assembly 1, prevent the product from shaking in the housing assembly 1, and thus prevent the ceramic cover in the relay 10 from cracking.

[0111] In some embodiments, a positioning groove 1d is provided on the side of the first shell wall 1a facing the second shell wall 1b, and a portion of the first noise reduction component 3 is located in the positioning groove 1d.

[0112] Thus, the positioning groove 1d provides a clear installation position reference for the first noise reduction component 3, ensuring that it is accurately installed in the designed position and maintains precise relative position with the first yoke body 211 and other related components. This ensures that the noise reduction component can effectively address the noise generated by the relay 10 during operation. Furthermore, accurately positioning the first noise reduction component 3 close to the noise source (first yoke body 211) and ensuring its tight fit with the first housing wall 1a via the positioning groove 1d better blocks noise from propagating outward through the first housing wall 1a, optimizing the noise reduction path and maximizing the noise reduction performance of the first noise reduction component 3, effectively reducing the noise during relay 10 operation.

[0113] Optionally, the relay body 2 also includes a main stationary contact and a ceramic cover. The ceramic cover is mounted on the yoke assembly 21, and the main stationary contact passes through the ceramic cover for connection with an external client (such as a copper busbar). Since a positioning groove 1d is provided on the side of the first shell wall 1a facing the second shell wall 1b, a portion of the first noise reduction component 3 is located in the positioning groove 1d. This ensures that the first noise reduction component 3 will not wobble, thereby preventing wobble on the side of the yoke assembly 21 away from the positioning groove 1d, and ultimately ensuring that the relay body 2 does not wobble relative to the shell assembly 1. Furthermore, this improves the stability between the main stationary contact on the relay body 2 and the client, preventing wobble between them and reducing the probability of cracking between the main stationary contact and the ceramic cover due to wobble.

[0114] In some embodiments, there are multiple relay bodies 2, which are spaced apart along the second direction. There are multiple first noise reduction elements 3, which are correspondingly arranged with the first yoke bodies 211 in the multiple relay bodies 2. The first direction and the second direction intersect perpendicularly.

[0115] It should be noted that the second direction is Figure 1 and Figure 2 in the Y direction.

[0116] Since this application includes multiple relay bodies 2, the relay 10 is a combined relay. A combined relay is an electrical switching device capable of multi-channel control, composed of multiple relay bodies 2, and can simultaneously control multiple circuits. The relay body 2 serves as the main working component of the combined relay, consisting of a drive mechanism, an actuating mechanism, and a contact mechanism. The drive mechanism closes or opens the contacts, thereby controlling the circuit's on / off state. It is important to note that multiple relay bodies 2 share a single housing assembly 1, forming a combined relay. This combined relay can control the circuit, reducing the failure rate and extending the service life of electrical equipment.

[0117] A twin relay is a device consisting of two independent relay bodies 2, which perform their functions through control signals. Each relay body 2 has its own independent control circuit and contact mechanism. In the circuit, when the control signal is energized, both relay bodies 2 will operate, realizing their functions. Based on the above description, the twin relay also belongs to the combined relay of this application. Here, the specific number of relay bodies 2 in the combined relay will not be elaborated.

[0118] Thus, since there are multiple first noise reduction components 3, and each of the multiple first noise reduction components 3 is correspondingly arranged with the first yoke body 211 in the multiple relay bodies 2, when the drive component impacts the first yoke body 211 and generates noise, the propagation of noise can be further reduced by the first noise reduction components 3, and the noise transmitted to the outside of the relay 10 during use can be further reduced.

[0119] In some embodiments, at least a portion of the first yoke bodies 211 are provided with through holes, the through holes penetrating the corresponding first yoke bodies 211 along a first direction; a portion of the first noise reduction element 3 is provided on the side of the first yoke body 211 facing the first shell wall 1a; another portion of the first noise reduction element 3 passes through the through holes.

[0120] Thus, on the one hand, since a portion of the first noise reduction component 3 is located on the side of the corresponding first yoke body 211 facing the first shell wall 1a, in the process of connecting this portion of the first noise reduction component 3 and the first yoke body 211, it is only necessary to connect this portion of the first noise reduction component 3 to the side of the first yoke body 211 facing the first shell wall 1a. This makes it convenient for installers to install this portion of the first noise reduction component 3 and the yoke assembly 21, thereby improving the processing and production efficiency of the relay 10.

[0121] On the other hand, since another part of the first noise reduction component 3 passes through the through hole, the tightness of the connection between this part of the first noise reduction component 3 and the first yoke body 211 can be improved, thereby improving the stability of the connection between this part of the first noise reduction component 3 and the yoke assembly 21 and the second housing 12. Furthermore, since this part of the first noise reduction component 3 passes through the through hole, when the position of the through hole is pre-set, the position of this part of the first noise reduction component 3 can be restricted through the through hole, so that this part of the first noise reduction component 3 is placed in a suitable position, thereby improving the performance of this part of the first noise reduction component 3.

[0122] In some embodiments, the first noise reduction component 3 is a one-piece molded structure.

[0123] In this way, on the one hand, the number of components and welding points of the first noise reduction component 3 can be reduced, thereby improving the overall strength of the first noise reduction component 3, and thus improving the overall strength and stability of the relay 10; on the other hand, the production line of the first noise reduction component 3 can be reduced, thereby shortening the production cycle of the first noise reduction component 3, thereby reducing the manufacturing cost of the first noise reduction component 3, and ultimately reducing the manufacturing cost of the relay 10.

[0124] In some embodiments, the elastic modulus of the first noise reduction component 3 is less than the elastic modulus of the yoke assembly 21.

[0125] Thus, since the elastic modulus of the first noise reduction component 3 is less than that of the elastic modulus of the yoke assembly 21, that is, the flexibility of the first noise reduction component 3 is greater than that of the yoke assembly 21, the vibration generated by the yoke assembly 21 can be absorbed by the flexible damping of the first noise reduction component 3, thereby reducing the vibration transmitted from the yoke assembly 21 to the housing assembly 1, and finally achieving the effect of noise reduction.

[0126] In some embodiments, the elastic modulus of the first noise reduction element 3 is less than the elastic modulus of the housing assembly 1.

[0127] Thus, since the elastic modulus of the first noise reduction component 3 is less than that of the elastic modulus of the shell assembly 1, that is, the flexibility of the first noise reduction component 3 is greater than that of the shell assembly 1, the vibration generated by the yoke assembly 21 can be absorbed by the flexible damping of the first noise reduction component 3, thereby reducing the vibration transmitted from the yoke assembly 21 to the shell assembly 1, and finally achieving the effect of noise reduction.

[0128] In some embodiments, the first noise reduction element 3 is an elastic element.

[0129] In this way, the elastic element can better conform to the surfaces of the yoke assembly 21 and the housing assembly 1 through its own elastic deformation, filling any gaps and reducing the channels for noise leakage. At the same time, the elastic element can change the propagation path of noise to a certain extent, increasing the attenuation of noise during propagation, thereby improving the noise reduction effect.

[0130] In some embodiments, see Figure 7 and Figure 8 As shown, the yoke assembly 21 includes a first yoke body 211, a second yoke body 213, and an extension 212. The first yoke body 211 is located at the end of the relay body 2 along the first direction, the second yoke body 213 is located at the middle of the relay body 2 along the first direction, and the extension 212 is connected between the first yoke body 211 and the second yoke body 213.

[0131] It should be noted that the first yoke body 211, the second yoke body 213 and the extension 212 can be an integral structure. Of course, the first yoke body 211, the second yoke body 213 and the extension 212 can also be a separate structure. Here, the connection method of the first yoke body 211, the second yoke body 213 and the extension 212 will not be limited or described in detail.

[0132] Thus, the first yoke body 211 is located at the end of the relay body 2 along the first direction, and the second yoke body 213 is located in the middle of the relay body 2 along the first direction. This arrangement can more comprehensively constrain and guide the magnetic field generated by the relay body 2. By setting the first yoke body 211 and the second yoke body 213 at different positions, the magnetic field distribution can be made more uniform and stable, reducing magnetic field leakage and improving the electromagnetic performance and working efficiency of the relay 10.

[0133] Furthermore, the extension 212 connects the first yoke body 211 and the second yoke body 213, forming an integral structural frame. This connection method can enhance the structural strength and stability of the yoke assembly 21, enabling it to better withstand the electromagnetic force and mechanical stress generated when the relay 10 is working, reducing the possibility of component damage or displacement due to vibration or external force, thereby improving the reliability and service life of the relay 10.

[0134] In some embodiments, the yoke assembly 21 further includes a second yoke body 213, which is located at the middle of the relay body 2 along a first direction; the relay 10 further includes a second noise reduction element 4, which is disposed within the housing assembly 1, and at least a portion of the second noise reduction element 4 is located between the second yoke body 213 and the inner wall of the housing assembly 1.

[0135] Because a second noise reduction component 4 is provided between the second yoke body 213 and the housing assembly 1, when the drive assembly impacts the second yoke body 213 and generates noise, the propagation of noise can be reduced by the second noise reduction component 4. This can reduce the noise transmitted from the relay 10 to the outside of the relay 10 during use, thereby meeting the user's usage requirements.

[0136] It should be noted that since the second yoke body 213 is closer to the noise source that generates noise in the relay 10, the second noise reduction component 4 is provided between the second yoke body 213 and the housing assembly 1. This allows the second noise reduction component 4 to be closer to the noise source, thereby further improving the noise reduction effect of the second noise reduction component 4.

[0137] In some embodiments, the second noise reduction element 4 abuts between the second yoke body 213 and the inner wall of the housing assembly 1.

[0138] Thus, since the second noise reduction component 4 abuts between the second yoke body 213 and the inner wall of the housing assembly 1, the second noise reduction component 4 can be subjected to two opposite forces by the second yoke body 213 and the housing assembly 1, thereby restricting the movement of the second noise reduction component 4 along the direction of the second yoke body 213 toward the housing assembly 1, thereby improving the tightness of the connection between the second noise reduction component 4 and the second yoke body 213 and the housing assembly 1.

[0139] Furthermore, since the first noise reduction component 3 is fixedly connected to at least one of the yoke assembly 21 and the housing assembly 1, it is understood that the direction in which the first noise reduction component 3 is fixedly connected to at least one of the yoke assembly 21 and the housing assembly 1 is different from the direction in which the second noise reduction component 4 abuts against the inner wall of the second yoke body 213 and the housing assembly 1. Therefore, through the cooperative action of the first noise reduction component 3 and the second noise reduction component 4, the cooperation between the first noise reduction component 3, the second noise reduction component 4, the housing assembly 1, and the yoke assembly 21 in all directions is made tighter, further enhancing the stability of the entire relay 10 structure in all directions. Simultaneously, since the first noise reduction component 3 and the second noise reduction component 4 are located at different positions on the yoke assembly 21 and the housing assembly 1, the noise reduction effect in all directions can be improved.

[0140] In some embodiments, the second yoke body 213 is a yoke plate.

[0141] Thus, the yoke plate, as a single plate structure, is easier to process and manufacture compared to other complex shapes, reducing production costs. At the same time, its flat surface facilitates assembly with other components, improving production efficiency.

[0142] In some embodiments, the relay 10 includes a first support member 5 located within the housing assembly 1. A second noise reduction member 4 is provided on at least one side of the second yoke body 213 along a third direction. The two sides of the second noise reduction member 4 along the first direction are a first side and a second side, respectively. The first support member 5 is located on the first side of the second noise reduction member 4 and is used to support the second noise reduction member 4. The first direction intersects the third direction perpendicularly.

[0143] It should be noted that the third party is... Figure 1 and Figure 2 The Z direction in the equation.

[0144] It should be further explained that the first support member 5 is located on the first side of the second noise reduction member 4, which is the side of the second noise reduction member 4 facing the direction of gravity. At this time, the first support member 5 and the second noise reduction member 4 are in contact.

[0145] Thus, the first support member 5 can stably fix the second noise reduction member 4 in a specific position within the housing assembly 1, ensuring that the second noise reduction member 4 will not shift or shake due to vibration, collision, or other factors during the operation of the relay 10. Since the second noise reduction member 4 needs to be accurately positioned between the second yoke body 213 and the housing assembly 1 to effectively perform its noise reduction function, the presence of the first support member 5 ensures the accuracy and stability of the position of the second noise reduction member 4, enabling it to continuously and reliably reduce the propagation of noise.

[0146] Furthermore, the first support member 5 provides additional support points and stability for the entire internal structure of the relay 10. It not only supports the second noise-reducing member 4 but also enhances the connection strength and overall integrity between components within the housing assembly 1 to a certain extent. When the relay 10 is subjected to external impact or internal vibration, the first support member 5 helps to disperse stress, reduce relative displacement and wear between components, protect the relay body 2 and other components, extend the service life of the relay 10, and ensure its long-term stable operation.

[0147] Specifically, the first support member 5 plays a supporting and positioning role for the second yoke body 213, which can ensure the installation height of the entire relay 10, thereby ensuring the height of the main contacts. This prevents the installation height of the main contacts from being too high or too low during customer assembly (such as when installing copper busbars), which would cause assembly stress to be transmitted to the ceramic cover, causing the ceramic cover to crack and leak air.

[0148] In some embodiments, the relay 10 includes a second support member 6 located within the housing assembly 1. A second noise reduction member 4 is provided on at least one side of the second yoke body 213 along a third direction. The two sides of the second noise reduction member 4 along a first direction are a first side and a second side, respectively. The second support member 6 is located on the second side of the second noise reduction member 4. The first direction intersects the third direction perpendicularly.

[0149] It should be noted that the second support member 6 is located on the second side of the second noise reduction member 4, which is the side of the second noise reduction member 4 that is away from the direction of gravity. At this time, the second support member 6 and the second noise reduction member 4 may or may not be in contact.

[0150] Thus, the second support member 6 cooperates with the first support member 5 located on the first side of the second noise reduction member 4 to form bidirectional support for the second noise reduction member 4. This makes the second noise reduction member 4 more securely fixed within the housing assembly 1, effectively preventing the second noise reduction member 4 from shifting, shaking, or deforming due to vibration, impact, or other external forces during the operation of the relay 10, ensuring that the second noise reduction member 4 is always in the optimal noise reduction position, thereby stably performing its noise reduction function.

[0151] Furthermore, the second support member 6 increases the stability and integrity of the internal structure of the relay 10. Working together with the first support member 5, it connects the second noise reduction member 4 more tightly with the other components of the relay 10, which helps to disperse the stress generated during the operation of the relay 10, reduce the relative movement and friction between the components, and reduce the risk of component damage due to long-term vibration, thereby improving the reliability and service life of the entire relay 10 structure.

[0152] Specifically, firstly, when the relay body 2 is fixed to the bottom wall of the housing assembly 1 with adhesive, the expansion of the adhesive pushes the entire relay body 2 upward. At this time, the second support 6 can limit the overall upward movement of the relay body 2, that is, it can restrict the upward movement of the second yoke body 213.

[0153] Secondly, it should be noted that the housing assembly 1 includes a first housing 11 and a second housing 12 connected together, which together form a receiving cavity. When the relay body 2 is not fixed to the housing assembly 1 with adhesive, the relay body 2 is confined inside the housing assembly 1, which can prevent the relay body 2 from shaking during movement and vibration. However, there will be tolerances between the first housing 11 and the second housing 12, which may result in the first housing 11 and the second housing 12 not being able to be assembled or not being able to limit the relay body 10. Since the second noise reduction component 4 is flexible, it can absorb the tolerances of the first housing 11 and the second housing 12 in the first direction without affecting the flexibility of the side of the second noise reduction component 4 that contacts the outer shell (i.e., the third shell wall 1c).

[0154] In addition, regardless of whether the relay body 2 and the housing assembly 1 are fixed with adhesive, the first support 5 and the second support 6 can press down on the second noise reduction component 4, thereby preventing the second noise reduction component 4 from falling off.

[0155] In some embodiments, the relay 10 includes a housing assembly 1, which includes two third housing walls 1c disposed opposite each other along a third direction, a relay body 2 located between the two third housing walls 1c, a second yoke body 213 extending along a third direction, and a second noise reduction element 4 disposed between at least one third housing wall 1c and the second yoke body 213; wherein the third direction intersects perpendicularly with the second direction.

[0156] Thus, the second yoke body 213 extends along a third direction, and a second noise reduction element 4 is provided between at least one third shell wall 1c and the second yoke body 213. This allows full use of the space between the two third shell walls 1c, and the second noise reduction element 4 can be reasonably arranged without increasing the overall volume of the relay 10, thereby achieving the noise reduction function.

[0157] Meanwhile, when the drive assembly impacts the second yoke body 213, generating noise, since the second yoke body 213 is one of the noise sources when the relay 10 is operating, placing the second noise reduction component 4 between the third shell wall 1c and the second yoke body 213 can directly block and absorb the noise. This arrangement allows the second noise reduction component 4 to act closer to the noise source, reducing noise loss during propagation, thereby more effectively reducing noise propagating from inside the relay 10 to the outside and improving the noise reduction effect.

[0158] In some embodiments, the housing assembly 1 includes a first housing 11 and a second housing 12 connected together, the first housing 11 and the second housing 12 surrounding a receiving cavity and arranged along a first direction; the third housing wall 1c includes a first sub-housing wall 1c1 and a second sub-housing wall 1c2, the first sub-housing wall 1c1 being located in the first housing 11 and the second sub-housing wall 1c2 being located in the second housing 12; a first support member 5 is provided on the side of the first sub-housing wall 1c1 facing the receiving cavity, and a second support member 6 is provided on the side of the second sub-housing wall 1c2 facing the receiving cavity; along the first direction, a second noise reduction member 4 is located between the first support member 5 and the second support member 6.

[0159] Thus, the housing assembly 1 is divided into a first housing 11 and a second housing 12. This modular design facilitates mold design and production processing during manufacturing. Different housings can be manufactured separately and then assembled, improving production efficiency and reducing manufacturing difficulty.

[0160] Furthermore, the first support member 5 and the second support member 6 support the second noise reduction member 4 from both sides, effectively limiting the movement of the second noise reduction member 4 in the first direction. Regardless of whether the relay 10 is subjected to vibration, impact or other external forces during operation, the second noise reduction member 4 can remain in the predetermined position, ensuring the stable operation of its noise reduction function.

[0161] In some embodiments, the second noise reduction element 4 abuts against the first support element 5 on one side along the first direction, and the second noise reduction element 4 abuts against the second support element 6 on the other side along the first direction.

[0162] Thus, by abutting against the first support member 5 and the second support member 6 on both sides, the second noise-reducing member 4 can be accurately positioned at a specific location between the second yoke body 213 and the housing assembly 1, preventing it from shifting or shaking within the receiving cavity and ensuring that it is always in a position that can effectively reduce noise, thus stably performing its noise-reducing function. Simultaneously, the first support member 5 and the second support member 6 provide support force to the second noise-reducing member 4 from both sides, ensuring that the second noise-reducing member 4 is subjected to uniform pressure in the first direction, avoiding deformation or damage due to uneven force. This helps maintain the integrity and performance stability of the second noise-reducing member 4, enabling it to continuously and effectively absorb and block noise during long-term use.

[0163] In some embodiments, along a third direction, the second noise reduction member 4 is provided with a groove 41 on the side facing the second yoke body 213, and the side of the second yoke body 213 facing the second noise reduction member 4 is embedded in the groove 41; wherein, the first direction intersects the third direction perpendicularly.

[0164] Thus, since the side of the second yoke body 213 facing the second noise reduction component 4 is embedded in the groove 41, the second noise reduction component 4 can be limited by the groove 41 to prevent the second noise reduction component 4 from separating from the second yoke body 213, thereby improving the tightness of the connection between the second noise reduction component 4 and the second yoke body 213, and thus improving the overall stability of the relay 10.

[0165] In some embodiments, the second noise reduction component 4 is a one-piece molded structure.

[0166] In this way, on the one hand, the number of components and welding points of the second noise reduction component 4 can be reduced, thereby improving the overall strength of the second noise reduction component 4, and thus improving the overall strength and stability of the relay 10; on the other hand, the production line of the second noise reduction component 4 can be reduced, thereby shortening the production cycle of the second noise reduction component 4, thereby reducing the manufacturing cost of the second noise reduction component 4, and ultimately reducing the manufacturing cost of the relay 10.

[0167] In some embodiments, the second noise reduction element 4 is an elastic element.

[0168] In this way, the elastic element can better conform to the surfaces of the second yoke body 213 and the housing assembly 1 through its own elastic deformation, filling any gaps and reducing the channels for noise leakage. At the same time, the elastic element can change the propagation path of noise to a certain extent, increasing the attenuation of noise during propagation, thereby improving the noise reduction effect.

[0169] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0170] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
