[0001] Related applications
[0002] This application claims priority to Chinese patent application filed on February 19, 2025, with application number 202520268488X and entitled "Relay", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of relay technology, and in particular to relays. Background Technology
[0004] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the input quantity changes to a specified degree. Relays can generate changes in physical quantities through electromagnetic effects, thereby controlling the circuit; a small current can control the switching on and off of a large current.
[0005] In related technologies, a relay includes a base, a coil frame, an iron core, a moving spring, and an armature. The coil is mounted on the base, the iron core is connected to the coil frame, and the armature is rotatably connected to the base, cooperating with the iron core, moving spring, and other components. When the relay is de-energized, the coil does not generate a magnetic field and exerts no electromagnetic force on the armature; when the relay is energized, the coil generates an electromagnetic force that drives the armature to move.
[0006] However, on the one hand, during the transportation of the relay, the relay will be affected by vibration, causing the armature part inside the relay to move up and down and twist left and right, and the contact point with the iron core and moving spring to change, resulting in large driving voltage dispersion during testing; on the other hand, during repeated testing, the armature part will also move up and down, resulting in large driving voltage dispersion. Summary of the Invention

[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] Referring to Figures 1, 2, 3, and 4, a relay 1 provided in one embodiment of this application includes a base 11, an armature assembly 12, a connecting shaft 13, and an elastic member 14. The armature assembly 12 is mounted on the base 11; one end of the connecting shaft 13 is connected to the base 11, and the other end passes through the armature assembly 12; the elastic member 14 is located on the side of the armature assembly 12 away from the base 11; one end of the elastic member 14 is connected to the end of the connecting shaft 13 away from the base 11, and a portion of the surface of the elastic member 14 abuts against a portion of the surface of the armature assembly 12.
[0052] The base 11 serves as a support structure for the relay 1, supporting and fixing other components within the relay 1. The armature assembly 12, as a functional component of the relay 1, converts the current of the input signal into a switching action. When the coil of the relay 1 receives sufficient current, it generates a magnetic field that causes the armature assembly 12 to move, leading to the contact or separation of the moving and stationary contacts (not shown in the figure), thereby achieving switch control and enabling the relay 1 to control a large current with a small current. Specifically, when the coil of the relay 1 receives sufficient current, a preset current is applied to the coil.
[0053] It should be noted that during the operation of relay 1, armature assembly 12 needs to cooperate with components such as iron core, yoke, moving spring, and stationary spring in relay 1 (all of which are shown in the figure). The connection method and positional relationship between armature assembly 12 and components such as iron core, yoke, moving spring, and stationary spring in relay 1 are not limited in this application and will not be elaborated here.
[0054] It should also be noted that the armature assembly 12 is a unified whole composed of multiple parts. Some parts are used to interact with the iron core, some parts are used to interact with the yoke, and some parts are used to interact with the moving spring, stationary spring, etc. This application does not limit the specific parts of the armature assembly 12, and will not elaborate further here.
[0055] It is understood that the armature assembly 12 can also be a one-piece molded structure. Part of the armature assembly 12 is used to interact with the iron core, part of the armature assembly 12 is used to interact with the yoke, and part of the armature assembly 12 is used to interact with the moving spring, stationary spring, etc. This application does not limit the specific type of the armature assembly 12. Of course, the armature assembly 12 can also be used in conjunction with other parts of the relay 1 according to actual usage requirements, and this application is not restrictive in this regard either.
[0056] For example, one end of the connecting shaft 13 is connected to the base 11, and the other end is passed through the armature assembly 12. That is, one end of the connecting shaft 13 is fixedly connected to the base 11. Under the action of the electromagnetic force of the coil in the relay 1, the armature assembly 12 will rotate around the axial direction of the connecting shaft 13, thereby realizing the switching of the relay 1 between different states to realize the control of the switch.
[0057] Furthermore, the elastic element 14 is located on the side of the armature assembly 12 away from the base 11. One end of the elastic element 14 is connected to the end of the connecting shaft 13 away from the base 11, and a portion of the surface of the elastic element 14 abuts against a portion of the surface of the armature assembly 12. That is, the elastic element 14 and the connecting shaft 13 are in a connected state, and a portion of the surface of the elastic element 14 abuts against a portion of the surface of the armature assembly 12. In other words, the force of the connection between the elastic element 14 and the connecting shaft 13, the force of the abutment between the elastic element 14 and the armature assembly 12, and the elastic deformation force generated by the elastic element 14 under the influence of the forces on both sides are all converted into a downward pressure of the elastic element 14 on the armature assembly 12. Thus, pressure can be applied to the armature assembly 12 through the elastic element 14. Under the action of pressure, the phenomenon of vertical movement of the armature assembly 12 can be reduced, thereby improving the stability of the armature assembly 12 and ensuring the stability of the parameters during the test of the relay 1.
[0058] At the same time, under the action of pressure, the pressure can also provide frictional force to the armature assembly 12 to resist left and right twisting, thereby reducing the occurrence of left and right twisting of the armature assembly 12, thus limiting the direction of left and right twisting of the armature assembly 12, and ensuring the stability of the parameters of the relay 1 during testing.
[0059] It should be noted that the connecting shaft 13 passes through the armature assembly 12, that is, there is a movable connection between the armature assembly 12 and the connecting shaft 13. When the relay 1 is energized, the resultant force of other forces on the armature assembly 12 is greater than the force of the elastic element 14 that resists the left and right twisting of the armature assembly 12. The armature assembly 12 can still move normally, so as not to affect the normal use of the relay 1.
[0060] Since one end of the elastic element 14 of this application is connected to the end of the connecting shaft 13 away from the base 11, and part of the surface of the elastic element 14 abuts against part of the surface of the armature assembly 12, when the relay 1 is subjected to vibration during the transportation of the relay 1, the pressure applied to the armature assembly 12 by the elastic element 14 can reduce the phenomenon of the armature assembly 12 moving up and down and twisting left and right inside the relay 1, thereby improving the stability of the armature assembly 12, and thus ensuring the stability of the parameters of the relay 1 during testing. For example, it can ensure that the driving voltage dispersion of the relay 1 during testing is small.
[0061] In some embodiments, referring to Figures 5, 6, and 7, the elastic member 14 includes an elastic body 141 and an extension 142. The elastic body 141 extends along a first direction, with one end connected to the end of the connecting shaft 13 away from the base 11. The extension 142 extends along a second direction, connected to the end of the elastic body 141 away from the connecting shaft 13, and at least a portion of the surface of the extension 142 abuts against a portion of the surface of the armature assembly 12. The first and second directions intersect.
[0062] It should be noted that the first direction is the X direction in Figure 1 and Figure 5, and the second direction is the Y direction in Figure 1 and Figure 5.
[0063] Thus, since the elastic body 141 and the extension 142 extend in two different directions, elastic deformation forces in two different directions can be provided by the elastic body 141 and the extension 142, thereby further increasing the pressure of the elastic element 14 on the armature assembly 12, thereby further improving the stability of the armature assembly 12, and further ensuring the stability of the parameters during the test of the relay 1.
[0064] In some embodiments, referring to FIG5, the extension 142 includes a first extension segment 1421 and a second extension segment 1422. The first extension segment 1421 and the second extension segment 1422 both extend along a second direction and are located on both sides of the elastic body 141 along the second direction.
[0065] Thus, since both the first extension segment 1421 and the second extension segment 1422 extend along the second direction and are located on both sides of the elastic body 141 along the second direction, that is, the elastic body 141, the first extension segment 1421 and the second extension segment 1422 extend in different directions respectively, on the one hand, the elastic body 141, the first extension segment 1421 and the second extension segment 1422 can provide elastic deformation force in different directions, thereby further increasing the pressure of the elastic element 14 on the armature assembly 12, thereby further improving the stability of the armature assembly 12, and further ensuring the stability of the parameters during the test of the relay 1; on the other hand, the extension of the elastic body 141, the first extension segment 1421 and the second extension segment 1422 in different directions can improve the overall stability of the elastic element 14, thereby improving the stability and reliability of the relay 1.
[0066] In some embodiments, as shown in Figures 5, 6 and 7, the elastic member 14 further includes a protrusion 143. The protrusion 143 is provided on the side of the extension 142 facing the armature assembly 12, and the protrusion 143 abuts against the armature assembly 12.
[0067] Thus, since the protrusion 143 abuts against the armature assembly 12, on the one hand, the contact surface between the elastic member 14 and the armature assembly 12 can be reduced, thereby reducing the friction between the elastic member 14 and the armature assembly 12. On the basis of applying pressure to the armature assembly 12 through the elastic member 14 to stabilize the armature assembly 12, when the relay 1 is in the energized state, the coil in the relay 1 can easily drive the armature assembly 12 to move, thereby ensuring the normal movement of the armature assembly 12 when the relay 1 is in the energized state.
[0068] In some embodiments, as shown in FIG5, the elastic body 141 has a hollow portion 1411, which penetrates the elastic body 141 along a third direction. The third direction intersects both the first and second directions.
[0069] It should be noted that the third direction is the Z direction in Figures 1 and 5.
[0070] Thus, since the elastic body 141 is provided with a hollow portion 1411, which extends through the elastic body 141 in the third direction, on the one hand, the contact surface between the elastic element 14 and the armature assembly 12 can be further reduced, thereby further reducing the friction between the elastic element 14 and the armature assembly 12. This ensures the normal movement of the armature assembly 12 when the relay 1 is energized. On the other hand, the elastic body 141 can have a certain degree of flexibility, thereby preventing the elastic element 14 from applying excessive pressure to the armature assembly 12, which could cause the armature assembly 12 to be unable to move, thus ensuring the reliability of the relay 1.
[0071] In some embodiments, the base 11 has a socket, and one end of the connecting shaft 13 away from the elastic member 14 is inserted into the socket. At least a portion of the cross-sectional area of the connecting shaft 13 along the third direction is larger than the cross-sectional area of the socket along the third direction. The third direction intersects both the first and second directions.
[0072] Optionally, the total cross-sectional area of the connecting shaft 13 along the direction perpendicular to the third direction is greater than the cross-sectional area of the socket along the direction perpendicular to the third direction. That is, when the connecting shaft 13 is inserted into the socket, the connecting shaft 13 and the socket are in an interference fit state. Thus, the elastic deformation of the connecting shaft 13 and the socket can be used to achieve a tight connection between the connecting shaft 13 and the socket, preventing the connecting shaft 13 and the base 11 from separating. This can improve the stability and reliability of the connection between the connecting shaft 13 and the base 11, and further ensure the stability between the elastic element 14 and the armature assembly 12 when the elastic element 14 applies a force to the armature assembly 12.
[0073] Optionally, the cross-sectional area of the connecting shaft 13 along the third direction is larger than the cross-sectional area of the socket along the third direction, and the cross-sectional area of the connecting shaft 13 along the third direction is smaller than the cross-sectional area of the socket along the third direction. Similarly, since the cross-sectional area of the connecting shaft 13 along the third direction is larger than the cross-sectional area of the socket along the third direction, when the area corresponding to this part of the cross-sectional area of the connecting shaft 13 is inserted into the socket, this part of the connecting shaft 13 and the socket are in an interference fit state. Thus, the elastic deformation of this part of the connecting shaft 13 and the socket can be used to achieve a tight connection between the connecting shaft 13 and the socket, preventing the connecting shaft 13 and the base 11 from separating.
[0074] Furthermore, since the cross-sectional area of the connecting shaft 13 along the third direction is smaller than the cross-sectional area of the socket along the third direction, there is a gap between this part of the area and the socket during the process of inserting the connecting shaft 13 into the socket. This part of the area can guide the installation and insertion process of the connecting shaft 13, which can facilitate the installation of the connecting shaft 13 and the base 11.
[0075] In some embodiments, the insertion hole includes a bottom hole, which is located on the side of the insertion hole away from the connecting shaft 13. Along a third direction, the distance between the end of the connecting shaft 13 away from the elastic member 14 and the bottom hole is greater than or equal to the distance between the end face of the connecting shaft 13 away from the base 11 and the armature assembly 12.
[0076] It should be noted that when the insertion hole is a through hole, the bottom of the hole in this application is the opening of the insertion hole on the side away from the elastic member 14; when the insertion hole is a blind hole, the bottom of the hole in this application is the bottom wall of the blind hole.
[0077] Optionally, along a third direction, the distance between the end of the connecting shaft 13 away from the elastic element 14 and the bottom of the hole is equal to the distance between the end face of the connecting shaft 13 away from the base 11 and the armature assembly 12. That is, the position of the connecting shaft 13 relative to the bottom of the hole can be changed. It can be understood that the closer the connecting shaft 13 is to the bottom of the hole, the closer the elastic element 14 is to the armature assembly 12. In other words, the closer the connecting shaft 13 is to the bottom of the hole, the more contact surface there is between the elastic element 14 and the armature assembly 12. Therefore, by controlling the distance between the connecting shaft 13 and the bottom of the hole, the distance between the elastic element 14 and the armature assembly 12 can be controlled, thereby controlling the contact surface between the elastic element 14 and the armature assembly 12. Ultimately, the force exerted by the elastic element 14 on the armature assembly 12 can be controlled. The pressure of the elastic element 14 on the armature assembly 12 can be adjusted by the insertion depth of the connecting shaft 13 relative to the hole, thus facilitating the operator's control over the stability of the armature assembly 12.
[0078] It should be noted that since the connecting shaft 13 and the socket are in an interference fit state, that is, although the connecting shaft 13 and the socket are tightly connected, when an external force is applied, the distance between the connecting shaft 13 and the bottom of the hole can still be controlled to change. Furthermore, when the connecting shaft 13 moves to any position relative to the bottom of the hole, the connecting shaft 13 is in a tight fit state with the socket, thereby ensuring the stability of the relay 1.
[0079] Optionally, along a third direction, the distance between the end of the connecting shaft 13 away from the elastic member 14 and the bottom of the hole is greater than the distance between the end face of the connecting shaft 13 away from the base 11 and the armature assembly 12. That is, based on the above embodiment, the movable distance between the connecting shaft 13 and the base 11 is greater than the adjustable distance between the elastic member 14 and the armature assembly 12. This allows for a larger adjustable distance between the connecting shaft 13 and the base 11, thereby preventing the elastic member 14 from not moving to the appropriate position when the connecting shaft 13 moves to the maximum distance, and allowing the connecting shaft 13 to have sufficient adjustable distance.
[0080] In some embodiments, along a third direction, the entire surface of the elastic member 14 facing the armature assembly 12 abuts against a portion of the surface of the armature assembly 12 facing the elastic member 14.
[0081] Thus, since the entire surface of the elastic element 14 facing the armature assembly 12 abuts against the partial surface of the armature assembly 12 facing the elastic element 14, that is, the force exerted by the elastic element 14 on the armature assembly 12 reaches its maximum value, at this time, the elastic element 14 can provide pressure to the armature assembly 12 to the maximum extent, thereby further improving the stability of the armature assembly 12 and ensuring the stability of the parameters during the test of the relay 1.
[0082] In some embodiments, the connecting shaft 13 and the elastic element 14 are welded together.
[0083] In this way, a tight fit between the connecting shaft 13 and the elastic element 14 can be ensured through welding, thereby guaranteeing the stability of the connection between the connecting shaft 13 and the elastic element 14, and thus providing stable pressure for the armature assembly 12. In addition, the welding process is fast, which can improve the processing efficiency between the connecting shaft 13 and the elastic element 14, thereby improving the production efficiency of the relay 1.
[0084] In some embodiments, the elastic element 14 is a compression spring.
[0085] For example, a compression spring applies an elastic force to an object, giving it a certain elastic deformation and rebound capability. Thus, since the elastic element 14 is a compression spring, pressure can be applied to the armature assembly 12 through the elastic deformation of the compression spring, thereby ensuring the stability of the armature assembly 12.
[0086] 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.
[0087] 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.
