[0045] In order to make the above objectives, characteristics and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the spirit of the present application, and that the present application is therefore not limited to the specific embodiments disclosed below.

[0047] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0048] In the present application, unless otherwise specifically defined and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In the present application, unless otherwise explicitly specified and limited, if there is a description such as "on" or "under" or the like between a first feature and a second feature, it means that the first and second features are in direct contact or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height. The first feature "below", "under" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 . An embodiment of the present application provides a relay 1, which comprises a base 11, an armature assembly 12, a connecting shaft 13 and a resilient 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 is arranged in the armature assembly 12; the resilient member 14 is arranged on the side of the armature assembly 12 away from the base 11; one end of the resilient member 14 is connected to the end of the connecting shaft 13 away from the base 11, and part of the surface of the resilient member 14 abuts part of the surface of the armature assembly 12.

[0051] Among them, the base 11 serves as a support structure of the relay 1, for supporting and fixing other parts in the relay 1, and the armature assembly 12 serves as a functional component in the relay 1, for converting the current of the input signal in the relay 1 into switching action. When the electromagnetic coil of the relay 1 obtains sufficient current, a magnetic field is generated to make the armature assembly 12 move, drive the moving contact and the stationary contact (not shown in the figure) to contact or separate, thereby realizing the control of the switch, and further realizing the function of the relay 1 to control large current by small current.

[0052] It should be noted that during the operation of the relay 1, the armature assembly 12 needs to cooperate with the core, yoke, moving spring, stationary spring and other components (all not shown in the figure) in the relay 1. The connection mode and positional relationship of the armature assembly 12 with the core, yoke, moving spring, stationary spring and other components in the relay 1 are not limited in the present application, and will not be described here.

[0053] At the same time, it should be noted that the armature assembly 12 is a unified whole composed of multiple components, part of the structure is used to act with the core, part of the structure is used to act with the yoke, part of the structure is used to act with the moving spring, stationary spring and the like. The specific components of the armature assembly 12 are not limited in the present application, and will not be described here.

[0054] It can be understood that the armature assembly 12 can also be a one-piece structure, and part of the armature assembly 12 is used for action with the iron core, part of the armature assembly 12 is used for action with the yoke, and part of the armature assembly 12 is used for action with the moving spring, the static spring, etc. The specific type of the armature assembly 12 is not limited by the present application. Of course, the armature assembly 12 can also be used in cooperation with other parts of the relay 1 according to actual use requirements, and the present application is not limited in this regard.

[0055] Specifically, one end of the connecting shaft 13 is connected to the base 11, and the other end is provided in the armature assembly 12, that is, one end of the connecting shaft 13 is fixedly connected to the base 11, and the armature assembly 12 rotates around the axial direction of the connecting shaft 13 under the action of the electromagnetic force of the coil in the relay 1, so that the switching between different states of the relay 1 can be realized to achieve the control of the switch.

[0056] Further, the elastic member 14 is arranged 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 part of the surface of the elastic member 14 abuts against part of the surface of the armature assembly 12. That is, the elastic member 14 is in a connected state with the connecting shaft 13, and part of the surface of the elastic member 14 abuts against part of the surface of the armature assembly 12. That is, the downward pressure of the elastic member 14 on the armature assembly 12 can be realized through the combined action of the force of the elastic member 14 connected with the connecting shaft 13, the abutting force between the elastic member 14 and the armature assembly 12, and the elastic deformation force of the elastic member 14 under the influence of the forces on both sides. Thus, the pressure of the elastic member 14 on the armature assembly 12 can be realized, and the phenomenon of the armature assembly 12 moving up and down can be reduced under the action of the pressure, so that the stability of the armature assembly 12 can be improved, and the stability of the parameters of the relay 1 during testing can be ensured.

[0057] At the same time, under the action of the pressure, the pressure can also provide a friction force to resist the left and right twisting of the armature assembly 12, so that the phenomenon of the left and right twisting of the armature assembly 12 can be reduced, and the direction of the left and right twisting of the armature assembly 12 can be limited, thereby ensuring the stability of the parameters of the relay 1 during testing.

[0058] It should be noted that the connecting shaft 13 is provided in the armature assembly 12, that is, the armature assembly 12 and the connecting shaft 13 are movably connected. When the relay 1 is in an energized state, the resultant force of other forces acting on the armature assembly 12 is greater than the force of the elastic member 14 resisting the left and right twisting of the armature assembly 12, and the armature assembly 12 can also move normally, so as not to affect the normal use of the relay 1.

[0059] Since one end of the elastic member 14 of the application is connected to the end of the connecting shaft 13 away from the base 11, part of the surface of the elastic member 14 abuts part of the surface of the armature assembly 12, so that during the transportation of the relay 1, when the relay 1 is vibrated, the up-and-down movement and left-and-right twisting of the armature assembly 12 inside the relay 1 can be reduced by the pressure applied by the elastic member 14 to the armature assembly 12, so that the stability of the armature assembly 12 can be improved, and the stability of the parameters of the relay 1 during testing can be ensured, for example, the driving voltage dispersion of the relay 1 during testing can be ensured to be smaller.

[0060] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 , the elastic member 14 includes an elastic body 141 and an extension 142. The elastic body 141 extends in a first direction, and one end of the elastic body 141 is connected to the end of the connecting shaft 13 away from the base 11. The extension 142 extends in a second direction, and is connected to the end of the elastic body 141 away from the connecting shaft 13, and at least part of the surface of the extension 142 abuts part of the surface of the armature assembly 12. Wherein, the first direction and the second direction intersect.

[0061] 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 .

[0062] Therefore, since the elastic body 141 and the extension 142 extend in two different directions respectively, the elastic deformation force in two different directions can be provided by the elastic body 141 and the extension 142, so that the pressure of the elastic member 14 on the armature assembly 12 can be further improved, and the stability of the armature assembly 12 can be further improved, and the stability of the parameters of the relay 1 during testing can be further ensured.

[0063] In some embodiments, as shown in Figure 5 , the extension 142 includes a first extension segment 1421 and a second extension segment 1422. Wherein, the first extension segment 1421 and the second extension segment 1422 both extend in the second direction, and are located on both sides of the elastic body 141 in the second direction.

[0064] Thus, since the first extension segment 1421 and the second extension segment 1422 both extend along the second direction and are located on two sides of the elastic body 141 along the second direction, i.e., the elastic body 141, the first extension segment 1421 and the second extension segment 1422 extend along different directions respectively, on the one hand, elastic deformation forces along different directions can be provided by the elastic body 141, the first extension segment 1421 and the second extension segment 1422, so that the pressure of the elastic member 14 on the armature assembly 12 can be further improved, so that the stability of the armature assembly 12 can be further improved, and the stability of the parameters of the relay 1 during testing can be further ensured; on the other hand, the stability of the elastic member 14 as a whole can be improved by the extension of the elastic body 141, the first extension segment 1421 and the second extension segment 1422 along different directions, and thus the stability and reliability of the relay 1 can be improved.

[0065] In some embodiments, as shown in Figure 5 、 Figure 6 and Figure 7 , the elastic member 14 further comprises a protruding portion 143. The protruding portion 143 is arranged on the side of the extension portion 142 facing the armature assembly 12, and the protruding portion 143 abuts against the armature assembly 12.

[0066] Thus, since the protruding portion 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, so that the friction between the elastic member 14 and the armature assembly 12 can be reduced, so that on the basis of applying pressure to the armature assembly 12 by the elastic member 14 to stabilize the armature assembly 12, the coil in the relay 1 can conveniently drive the armature assembly 12 to move when the relay 1 is in the energized state, so that the normal movement of the armature assembly 12 can be ensured when the relay 1 is in the energized state.

[0067] In some embodiments, as shown in Figure 5 , the elastic body 141 is provided with a hollow portion 1411 which penetrates through the elastic body 141 along a third direction. The third direction intersects with the first direction and the second direction.

[0068] It should be noted that the third direction is the Z direction in Figure 1 and Figure 5 .

[0069] Thus, due to the fact that the elastic body 141 is provided with the hollow part 1411, the hollow part 1411 penetrates the elastic body 141 along the third direction, on the one hand, the contact surface between the elastic member 14 and the armature assembly 12 can be further reduced, so that the friction between the elastic member 14 and the armature assembly 12 can be further reduced, and the normal movement of the armature assembly 12 can be ensured when the relay 1 is in the energized state; on the other hand, the elastic body 141 can have a certain flexibility, so that the pressure applied by the elastic member 14 to the armature assembly 12 is not too large to cause the armature assembly 12 to be unable to move, thereby ensuring the reliability of the relay 1.

[0070] In some embodiments, the base 11 is provided with a socket, and the end of the connecting shaft 13 away from the elastic member 14 is inserted into the socket. The cross-sectional area of the connecting shaft 13 along a direction perpendicular to the third direction is greater than the cross-sectional area of the socket along a direction perpendicular to the third direction. The third direction intersects both the first direction and the second direction.

[0071] Alternatively, the cross-sectional area of the connecting shaft 13 along a direction perpendicular to the third direction is greater than the cross-sectional area of the socket along a 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, so that the elastic deformation of the connecting shaft 13 and the socket can be utilized to achieve a tight connection between the connecting shaft 13 and the socket, preventing the separation between the connecting shaft 13 and the base 11, thereby improving the stability and reliability of the connection between the connecting shaft 13 and the base 11, and further ensuring the stability between the elastic member 14 and the armature assembly 12 when the elastic member 14 applies a force to the armature assembly 12.

[0072] Alternatively, the cross-sectional area of the connecting shaft 13 along a direction perpendicular to the third direction is greater than the cross-sectional area of the socket along a 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, so that the elastic deformation of the connecting shaft 13 and the socket can be utilized to achieve a tight connection between the connecting shaft 13 and the socket, preventing the separation between the connecting shaft 13 and the base 11.

[0073] In addition, due to the fact that the cross-sectional area of the connecting shaft 13 along a direction perpendicular to the third direction is less than the cross-sectional area of the socket along a direction perpendicular to the third direction, so that during the insertion of the connecting shaft 13 into the socket, there is a gap between the connecting shaft 13 and the socket, so that the installation and insertion process of the connecting shaft 13 can be guided through the gap, and the installation of the connecting shaft 13 and the base 11 can be facilitated.

[0074] In some embodiments, the insertion hole comprises a hole bottom, the hole bottom is arranged on the side of the insertion hole away from the connecting shaft 13, and the distance between the end of the connecting shaft 13 away from the elastic member 14 and the hole bottom in the third direction is greater than or equal to the distance between the end face of the end of the connecting shaft 13 away from the base 11 and the armature assembly 12.

[0075] It should be noted that when the insertion hole is a through hole, the hole bottom in the present application is the hole opening on the side of the insertion hole away from the elastic member 14; when the insertion hole is a blind hole, the hole bottom in the present application is the hole bottom wall of the blind hole.

[0076] Alternatively, the distance between the end of the connecting shaft 13 away from the elastic member 14 and the hole bottom in the third direction is equal to the distance between the end face of the end 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 hole bottom can be changed. It can be understood that the closer the distance between the connecting shaft 13 and the hole bottom, the closer the distance between the elastic member 14 and the armature assembly 12, that is, the closer the distance between the connecting shaft 13 and the hole bottom, the more surfaces of the elastic member 14 abutting the armature assembly 12, so that by controlling the distance between the connecting shaft 13 and the hole bottom, the distance between the elastic member 14 and the armature assembly 12 can be controlled, and then the surface of the elastic member 14 abutting the armature assembly 12 can be controlled, and finally the force exerted by the elastic member 14 on the armature assembly 12 can be controlled. The pressure of the elastic member 14 on the armature assembly 12 can be adjusted by the insertion depth of the connecting shaft 13 relative to the insertion hole, so that the operator can conveniently control the stability of the armature assembly 12.

[0077] It should be noted that since the connecting shaft 13 and the insertion hole are in an interference fit state, that is, although the connecting shaft 13 and the insertion hole are tightly connected, when an external force is applied, the distance between the connecting shaft 13 and the hole bottom can still be controlled to change, and when the connecting shaft 13 moves to any position relative to the hole bottom, the connecting shaft 13 is still in a tightly fitted state with the insertion hole, thereby ensuring the stability of the relay 1.

[0078] Alternatively, the distance between the end of the connecting shaft 13 away from the elastic member 14 and the hole bottom in the third direction is greater than the distance between the end face of the end of the connecting shaft 13 away from the base 11 and the armature assembly 12, that is, on the basis of 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, so that the connecting shaft 13 and the base 11 have a greater adjustment distance, thereby avoiding the situation that when the connecting shaft 13 moves to the maximum distance, the elastic member 14 has not moved to the appropriate position, and the connecting shaft 13 has sufficient adjustment distance.

[0079] In some embodiments, all the surfaces of the elastic member 14 on the side toward the armature assembly 12 abut the part of the surface of the armature assembly 12 toward the elastic member 14 in the third direction.

[0080] Thus, since the entire surface of the elastic member 14 on the side facing the armature assembly 12 is in abutment with the partial surface of the armature assembly 12 facing the elastic member 14, i.e., the force exerted by the elastic member 14 on the armature assembly 12 reaches the maximum value, the elastic member 14 can provide the armature assembly 12 with the pressure to the greatest extent, thereby further improving the stability of the armature assembly 12 and ensuring the stability of the parameters of the relay 1 during testing.

[0081] In some embodiments, the connecting shaft 13 and the elastic member 14 are connected by welding.

[0082] Thus, the close fit between the connecting shaft 13 and the elastic member 14 can be ensured by welding, thereby ensuring the stability of the connection between the connecting shaft 13 and the elastic member 14 and providing the armature assembly 12 with stable pressure. In addition, the welding process is fast, thereby improving the efficiency of the processing between the connecting shaft 13 and the elastic member 14 and the production efficiency of the relay 1.

[0083] In some embodiments, the elastic member 14 is a compression spring.

[0084] Specifically, the compression spring exerts an elastic force on an object, making it have a certain elastic deformation and resilience. Thus, since the elastic member 14 is a compression spring, the elastic deformation of the compression spring can be used to exert pressure on the armature assembly 12, thereby ensuring the stability of the armature assembly 12.

[0085] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0086] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
