Pushing seat, pushing assembly and relay

Abstract

This application relates to a push base, a push assembly, and a relay. The push base is configured to be movably mounted in a mounting housing. The push base includes: a main body; and a plurality of limiting parts spaced apart on the periphery of the main body, with the limiting parts facing the inner wall of the mounting housing, configured to limit the push base within the mounting housing. Thus, through the cooperation of the multiple limiting parts with the mounting housing, the push base can be limited, ensuring that it can only move relative to the mounting housing and cannot deflect or tilt relative to it, thereby guaranteeing that the push base always moves linearly along a preset trajectory. This not only avoids contact position offset or poor contact caused by push base rotation, but also eliminates additional mechanical wear and noise caused by shaking. Simultaneously, it helps maintain constant contact gap and overtravel of the relay, improving the relay's vibration resistance, mechanical life, and reliability of contact action.

Description

Technical Field

[0001] This application relates to the field of power electrical technology, and in particular to a drive base, drive assembly and relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] In current relays, the actuator's reciprocating motion is unstable, resulting in poor contact consistency between the moving and stationary contacts, which affects the stability and reliability of the relay's operation. Summary of the Invention

[0049] A relay includes a stationary contact, a frame, a mounting housing, a magnetic circuit assembly, an insulating cover, and an actuating assembly as described in any of the foregoing technical features;

[0050] The pushing component is partially disposed in the mounting housing. The push rod of the pushing component passes through the mounting housing. The frame plate covers the mounting housing. The insulating cover is disposed on the side of the frame plate away from the mounting housing. The stationary contact passes through the insulating cover and is opposite to the moving contact in the pushing component along a third direction. The magnetic circuit assembly is disposed on the side of the mounting housing away from the frame plate and drives the push rod to cause the moving contact to contact or separate from the stationary contact along a third direction.

[0051] In one embodiment of this application, the mounting housing is a magnetic housing or a ceramic cover.

[0052] In one embodiment of this application, the actuating component includes at least two moving contacts, and the relay includes at least four stationary contacts, with each moving contact having two stationary contacts at each end.

[0053] In one embodiment of this application, the insulating cover has two insulating cavities, and the two insulating cavities are independent of each other;

[0054] Each of the insulating cavities is provided with a static contact corresponding to at least two conductive paths, and the moving contact contacts the corresponding static contact in the insulating cavity to make the corresponding conductive path open.

[0055] In one embodiment of this application, the relay includes an insulating cover, the insulating cover having a partition portion that divides the inner cavity of the insulating cover into two insulating cavities;

[0057] By adopting the above technical solution, this application has at least the following technical effects:

[0058] The push base, push assembly, and relay of this application, wherein the push base is movably mounted into the mounting housing along a third direction, and the push base is confined within the mounting housing by multiple limiting parts on the periphery of the main body facing the inner wall of the mounting housing. When the push base tends to rotate or tilt, the limiting parts can abut against the inner wall of the mounting housing to limit the rotation or tilt of the push base. In this way, the push base can be limited by the cooperation of multiple limiting parts with the mounting housing, so that the push base can only move relative to the mounting housing along a third direction and cannot deflect relative to the mounting housing, preventing the push base from deflecting or tilting under long-term high-frequency operation of the relay or external vibration interference, thereby ensuring that the push base always moves linearly along a preset trajectory. In this way, not only can the problem of contact position displacement or poor contact caused by the rotation of the push base be avoided, but also the additional mechanical wear and noise caused by shaking can be eliminated. At the same time, it helps to maintain the contact gap and overtravel of the relay constant, and improves the vibration resistance, mechanical life and contact operation reliability of the relay. Meanwhile, the limiting part, after limiting the push base, can also prevent the push base from deflecting or moving erratically. This reduces the eccentric torque on the push base, preventing it from moving smoothly along the preset straight direction. Furthermore, compared to the method of limiting the push base by having its entire outer wall surface contact the inner wall of the mounting housing, the method of limiting the push base by the limiting part has the characteristics of low frictional resistance and smooth movement. Moreover, the limiting part is integrated into the periphery of the main body, without adding extra parts, and does not require complex assembly and adjustment. Its compact structure makes it suitable for relays with limited space. Attached Figure Description

Detailed Implementation

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0087] Understandably, a relay is an electronic control device that plays a role in circuits such as automatic adjustment, safety protection, and circuit switching. In current relays, the actuator's reciprocating motion is unstable, leading to poor contact consistency between the moving and stationary contacts, which affects the stability and reliability of the relay's operation.

[0088] For this purpose, please refer to Figures 1 to 3 , Figure 12 , Figure 13 This application provides a pusher seat 110. The pusher seat 110 is used in the pusher assembly 100 of the relay 10. Figure 1 This is a schematic diagram of a relay 10 according to an embodiment of this application. Figure 2 for Figure 1 A cross-sectional view of the relay 10 of the first embodiment shown. Figure 3 for Figure 2 The diagram shown is a partial exploded view of the relay 10. Figure 12 for Figure 1 A cross-sectional view of the relay 10 of the second embodiment shown. Figure 13 for Figure 12 The diagram shows a partially exploded view of a relay 10 according to one embodiment. Optionally, the relay 10 is an electromagnetic relay or other types of relays.

[0089] To better illustrate the specific structure of relay 10, a brief schematic diagram of relay 10 and actuation assembly 100 is provided below. (See attached diagram.) Figures 1 to 3 , Figure 12 , Figure 13 In one embodiment, the relay 10 includes a stationary contact 200, a frame 300, a mounting housing, a magnetic circuit assembly 500, an insulating cover 600, and a push assembly 100 as described in this application. The push assembly 100 is partially disposed in the mounting housing and passes through the mounting housing. The frame 300 covers the mounting housing. The insulating cover 600 is disposed on the side of the frame 300 away from the mounting housing. The stationary contact 200 passes through the insulating cover 600 and is opposite to the moving contact 120 in the push assembly 100 along a third direction. The magnetic circuit assembly 500 is disposed on the side of the mounting housing away from the insulating cover 600 and drives the push rod 130 to cause the moving contact 120 to contact or separate from the stationary contact 200 along a third direction.

[0090] First direction, second direction, and third direction, such as Figure 1 , Figure 3 and Figure 13 As shown, the width and front-back directions of the relay 10 are denoted as the first direction, the length and left-right directions of the relay 10 are denoted as the second direction, and the height and up-down directions of the relay 10 are denoted as the third direction. The first, second, and third directions are perpendicular to each other. Furthermore, these first, second, and third directions apply to the relay 10 and all its components, and will not be elaborated further below.

[0091] Optionally, the mounting housing is a magnetically conductive housing 400. Of course, in other embodiments, the mounting housing may also be a ceramic cover. This application only uses a magnetically conductive housing 400 as an example for illustration. The magnetically conductive housing 400 is disposed above the magnetic circuit assembly 500 along a third direction. The pushing assembly 100 is partially located within the magnetically conductive housing 400, and the bottom of the pushing assembly 100 extends through the magnetically conductive housing 400 into the magnetic circuit assembly 500. That is, the pushing assembly 100 is partially located within the magnetically conductive housing 400 and partially within the magnetic circuit assembly 500. The magnetic circuit assembly 500 is the power source for the movement of the pushing assembly 100. After being energized, the magnetic circuit assembly 500 can drive the pushing assembly 100 to move up and down along a third direction. Optionally, the magnetically conductive housing 400 is a magnetically conductive cup, such as a yoke cup.

[0092] A frame plate 300 is disposed above the magnetic housing 400, and an insulating cover 600 is disposed above the frame plate 300. That is, the frame plate 300 is positioned between the insulating cover 600 and the magnetic housing 400, achieving connection and sealing between them. This ensures the airtightness between the insulating cover 600 and the magnetic housing 400, while also providing insulation and electrical isolation, thus guaranteeing the electrical safety of the relay 10. Optionally, the insulating cover 600 is a ceramic cover.

[0093] The stationary contact 200 passes through the insulating cover 600, meaning that part of the stationary contact 200 is located inside the insulating cover 600, and part is located outside the insulating cover 600. The portion of the stationary contact 200 outside the insulating cover 600 can be electrically connected to an external circuit to connect the relay 10 to the external circuit, while the portion of the stationary contact 200 inside the insulating cover 600 can be opposite to the actuating assembly 100 in a third direction. When the magnetic circuit assembly 500 drives the actuating assembly 100 to rise or fall in a third direction, the actuating assembly 100 can contact or separate from the stationary contact 200, thereby realizing the on or off control of the external circuit.

[0094] See Figures 2 to 5 , Figures 7 to 10 , Figures 12 to 15 , Figures 17 to 20In one embodiment, the pushing component 100 includes a movable contact 120 and a pushing seat 110 as described in this application. The movable contact 120 is disposed on the pushing seat 110 and extends out of the pushing seat 110.

Figure 17 for Figure 14 The first modified diagram of the push assembly 100 shown is shown. Figure 18 for Figure 14 The second modified diagram of the push assembly 100 shown is shown. Figure 19 for Figure 18 A schematic diagram of the pusher seat 110 in the pusher assembly 100 from one perspective. Figure 20 for Figure 19 The schematic diagram of the pusher seat 110 shown from another perspective.

[0095] The push base 110 is the main structure of the push assembly 100. The push base 110 is movably disposed within the magnetic housing 400 along a third direction. A push rod 130 is mounted on the bottom of the push base 110. The push rod 130 can pass through the magnetic housing 400 and connect to the magnetic circuit assembly 500. The push rod 130 will be mentioned later. The magnetic circuit assembly 500 can drive the push base 110 to move along a third direction, causing the push base 110 to rise or fall within the magnetic housing 400.

[0096] The moving contact 120 is the component of the relay 10 that enables it to turn on and off. The moving contact 120 is partially disposed within the push base 110 and partially located outside the push base 110. The moving contact 120 extends outward from the outside of the push base 110 toward the stationary contact 200, and the moving contact 120 and the stationary contact 200 are opposite each other in a third direction. Optionally, the push base 110 is made of insulating material. Optionally, the moving contact 120 is a moving spring.

[0097] When the magnetic circuit assembly 500 drives the push base 110 to rise in a third direction, the push base 110 can simultaneously drive the moving contact 120 to rise, so that the moving contact 120 contacts the stationary contact 200, thereby turning on the relay 10. When the magnetic circuit assembly 500 drives the push base 110 to fall in a third direction, the push base 110 can simultaneously drive the moving contact 120 to fall, so that the moving contact 120 separates from the stationary contact 200, thereby turning off the relay 10.

[0098] Furthermore, when the moving contact 120 contacts the stationary contact 200, it achieves elastic contact, ensuring reliable elastic contact and thus improving the on / off synchronization of the relay 10, thereby extending the service life and electrical stability of the relay 10. Additionally, when the moving contact 120 abuts against the stationary contact 200, it can press the stationary contact 200 firmly to adapt to the contact gap, avoiding problems such as poor contact, intermittent contact, and arcing, and ensuring stable contact during long-term repeated on / off cycles of the relay 10.

[0099] Thus, the relay 10, through the push base 110, drives the moving contact 120 to rise or fall in a third direction, so that the moving contact 120 can contact or separate from the stationary contact 200, thereby realizing the on or off control of the relay 10. Furthermore, the push base 110 enables the insulated installation of the moving contact 120, achieving insulation isolation between the moving contact 120 and other components in the relay 10, thus ensuring the performance of the relay 10.

[0100] Meanwhile, when the actuating component 100 contacts the stationary contact 200 via the moving contact 120, the moving contact 120 can also ensure the stability and reliability of its contact with the stationary contact 200, thereby improving the stability and reliability of the relay 10's operation. Furthermore, by integrating at least two moving contacts 120 into the actuating base 110, the relay 10's size can be reduced, its integration level increased, and it can be made suitable for use in confined internal spaces such as miniature switches, relays, and switching components.

[0101] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18In one embodiment, the moving contact 120 includes a mounting body 121, two support bodies 122, and two contact bodies 123. One end of each support body 122 is connected to the mounting body 121, and the other end extends away from the mounting body 121 and toward the stationary contact 200. The two support bodies 122 are disposed opposite to each other at both ends of the mounting body 121. Each contact body 123 is disposed at the end of a support body 122 away from the mounting body 121 and extends away from the other support body 122.

[0102] The mounting body 121 is the component connecting the moving contact 120 and the push seat 110. The support body 122 is the component in the moving contact 120 that provides buffering and support. The contact body 123 is the component that contacts the moving contact 120 and the stationary contact 200. The length of the mounting body 121 extends along the second direction. The two support bodies 122 are located at both ends of the mounting body 121 along the second direction and extend relative to the mounting body 121 toward the stationary contact 200. At this time, the two support bodies 122 and the mounting body 121 roughly form a U-shaped structure.

[0103] The contact body 123 is equivalent to the flange of the support body 122. Each support body 122 is connected to a contact body 123 at its top end. The contact body 123 extends toward the outside of the moving contact 120. Here, the inner side refers to the space within the two support bodies 122, and the outer side refers to the space outside the two support bodies 122. The principle of setting the inner and outer sides is also used for other components, which will not be repeated hereafter.

[0104] Two contact bodies 123 are positioned on top of the corresponding support body 122, and both contact bodies 123 extend outwards simultaneously, giving the moving contact 120 a U-shaped structure with an outward flange. When the magnetic circuit assembly 500 drives the push base 110 to raise the moving contact 120, the moving contact 120 can contact the stationary contact 200 through the contact body 123, thereby achieving the conduction control of the relay 10.

[0105] Meanwhile, after the moving contact 120 comes into contact with the stationary contact 200, the moving contact 120 presents a U-shaped structure with an outer flange, which forces the current or mechanical stress to be conducted along the bending path. Compared with the previous structure, the moving contact 120 of this application can effectively absorb and disperse the lateral impact load and temperature stress generated by thermal expansion and contraction during the movement of the moving contact 120, avoid local stress concentration, and prevent the moving contact 120 from breaking and failing.

[0106] Furthermore, when the contact body 123 contacts the stationary contact 200, the contact surface of the contact body 123 is larger than the contact surface of the stationary contact 200 to ensure that the contact body 123 and the stationary contact 200 are in full contact, thereby improving the stability and current carrying capacity of the electrical contact between the stationary contact 200 and the moving contact 120, and improving the heat dissipation effect of the moving contact 120, which is beneficial to the heat dissipation of the moving contact 120, thereby improving the reliability of the relay 10 operation.

[0107] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, one moving contact 120 corresponds to two stationary contacts 200. The moving contact 120 is arranged along a second direction, and the two stationary contacts 200 corresponding to the moving contact 120 are spaced apart along the second direction on the insulating cover 600. Each stationary contact 200 corresponds to a contact body 123 of the moving contact 120. When the magnetic circuit assembly 500 drives the pusher 110 to raise the moving contact 120, each contact body 123 abuts against the corresponding stationary contact 200.

[0108] When two stationary contacts 200 are simultaneously connected to an external circuit, and the magnetic circuit assembly 500 drives the push base 110 to move the moving contact 120 to contact the two stationary contacts 200 simultaneously, the moving contact 120 abuts against the corresponding stationary contact 200 through the two contact bodies 123 respectively. At this time, the moving contact 120 and the two stationary contacts 200 can form a conductive path so that the relay 10 can be connected to the external circuit.

[0109] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, the contact body 123 includes a connecting portion 1231 and a contact portion 1232. The connecting portion 1231 connects the support body 122 and the contact portion 1232, and the contact portion 1232 is configured to contact or separate from the stationary contact member 200. Figure 3 As shown, the contact body 123 is divided into a connecting portion 1231 and a contact portion 1232 along the second direction. The connecting portion 1231 can realize the connection between the supporting body 122 and the contact portion 1232.

[0110] This application has a connecting portion 1231 in the contact body 123. The connecting portion 1231 is located between the contact portion 1232 and the support body 122, which can make a certain distance between the contact portion 1232 and the support body 122. When the static contact member 200 abuts against the contact portion 1232, the force of the static contact member 200 on the contact portion 1232 can cause the connecting portion 1231 to deform relative to the support body 122, avoid stress concentration, and facilitate the contact between the contact body 123 and the static contact member 200.

[0111] Meanwhile, the contact portion 1232 also increases the contact area between the contact body 123 and the stationary contact 200. Understandably, the cross-sectional area of ​​the contact portion 1232 is larger than that of the stationary contact 200. Thus, when the stationary contact 200 contacts the contact portion 1232, the end of the stationary contact 200 only needs to abut against any position of the contact portion 1232 to achieve contact between the stationary contact 200 and the moving contact 120, thereby realizing the conduction control of the relay 10. In this way, the contact portion 1232 increases the contact area between the contact body 123 and the stationary contact 200, thereby improving the stability of the contact between the stationary contact 200 and the moving contact 120.

[0112] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, the dimension of the connecting portion 1231 along the first direction is smaller than the dimension of the contact portion 1232 along the first direction. That is, the sidewall of the contact portion 1232 along the first direction protrudes beyond the outer wall of the connecting portion 1231 along the first direction. In this way, the end of the contact body 123 connected to the support body 122 through the connecting portion 1231 has a contracted structure to increase the flexibility of the contact body 123 and ensure that the contact body 123 can reliably contact the static contact member 200.

[0113] Meanwhile, after the connecting portion 1231 connects the contact portion 1232 and the support body 122, it can also prevent breakage at the connection between the contact body 123 and the support body 122. Furthermore, the connecting portion 1231 can serve as the main elastic deformation zone of the contact body 123, so that when the moving contact 120 is subjected to pressure or vibration, the deformation mainly occurs in the connecting portion 1231, without affecting the overall plastic deformation of the moving contact 120.

[0114] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, the contact portion 1232 and the connecting portion 1231 are an integral structure. That is, the contact portion 1232 and the connecting portion 1231 are integrally formed. This ensures the structural strength and conductivity of the contact body 123 and prevents breakage between the contact portion 1232 and the connecting portion 1231, thereby improving the reliability of the contact between the static contact 200 and the dynamic contact 120.

[0115] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18In one embodiment, the mounting body 121, the supporting body 122, and the contact body 123 are an integral structure. That is, the mounting body 121, the supporting body 122, and the contact body 123 are integrally molded. This ensures the structural strength and conductivity of the moving contact 120 and prevents breakage at the connection points of the mounting body 121, the supporting body 122, and the contact body 123, thereby improving the reliability of the contact between the static contact 200 and the moving contact 120.

[0116] See Figures 3 to 5 , Figures 7 to 10 In the first embodiment of this application, the mounting body 121, the supporting body 122, and the contact body 123 are conductive sheets. That is, the moving contact 120 is a conductive sheet. This results in a thinner sheet, ensuring the flexibility and cushioning performance of the moving contact 120, preventing breakage when it contacts the stationary contact 200. Simultaneously, it achieves conductive contact between the stationary contact 200 and the moving contact 120, improving the reliability and stability of the relay 10's operation. Optionally, the moving contact 120 may be a conductive metal sheet.

[0117] See Figures 12 to 14 , Figure 17 and Figure 18 In the second embodiment of this application, the mounting body 121, the supporting body 122, and the contact body 123 are conductive metal plates. That is, the mounting body 121, the supporting body 122, and the contact body 123 have a certain thickness. This improves the structural strength of the moving contact 120 and also enhances its current-carrying capacity, enabling the relay 10 to be used in high-current scenarios.

[0118] Understandably, the moving contact 120 in the first embodiment has a certain degree of flexibility, thus ensuring contact stability during contact with the stationary contact 200. In the second embodiment, the moving contact 120 has a certain degree of rigidity, ensuring its structural strength. Furthermore, a compression spring 140 is provided below the moving contact 120 to provide cushioning, further ensuring the stability of the contact between the moving contact 120 and the stationary contact 200. The compression spring 140 will be discussed later.

[0119] Furthermore, in the first embodiment, the moving contact 120 has a certain degree of flexibility, resulting in a relatively small current-carrying capacity. Consequently, the relay 10 is used in low-current scenarios; for example, the relay 10 is a 1A relay or other low-current relays. In the second embodiment, the moving contact 120 has a certain degree of rigidity and a larger current-carrying capacity, allowing the relay 10 to be used in high-current scenarios. For example, the relay 10 is a 120A relay or other high-current relays.

[0120] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, the movable contact 120 is disposed behind the push base 110, the mounting body 121 is at least partially located in the push base 110, and the support body 122 and the contact body 123 are located outside the push base 110. The mounting body 121 is partially disposed in the push base 110, and both ends of the mounting body 121 protrude from the push base 110 along a second direction. That is, the mounting body 121 is partially disposed in the push base 110. In this way, the connection between the support body 122 and the mounting body 121 is exposed in the push base 110, and the support body 122 can swing relative to the mounting body 121 along the second direction, increasing the flexibility and cushioning performance of the movable contact 120.

[0121] When the push base 110 drives the moving contact 120 to contact the stationary contact 200, the moving contact 120 has flexibility and buffering properties, so that it can effectively absorb and disperse the lateral impact force and thermal expansion and contraction stress experienced by the moving contact 120 during its movement, preventing stress concentration at a certain point from causing the moving contact 120 to break, thus improving the reliability of the moving contact 120 and thereby improving the stability and reliability of the relay 10's operation. Of course, in other embodiments, the mounting body 121 can also be completely disposed in the push base 110, and the support body 122 can extend through the push base 110.

[0122] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the contact body 123 is arranged parallel to the mounting body 121. That is, the contact body 123 can extend in a horizontal direction. In this way, when the stationary contact 200 extends in a third direction, and the moving contact 120 contacts the stationary contact 200, the contact body 123 can abut against the stationary contact 200 in a planar manner, rather than contacting the stationary contact 200 at an angle, thus ensuring the contact area between the moving contact 120 and the stationary contact 200 and improving the stability of the relay 10 contact.

[0123] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the moving contact 120 further includes a first transition section 125, which transitionally connects the mounting body 121 and the support body 122. The first transition section 125 smoothly connects the mounting body 121 and the support body 122, and protrudes outwards from the moving contact 120. This allows for a smooth transition between the mounting body 121 and the support body 122, avoiding sharp edges and stress concentration. Furthermore, the smooth first transition section 125 increases the flexibility and cushioning performance of the moving contact 120, preventing breakage.

[0124] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the movable contact 120 further includes a second transition section 126, which smoothly connects the support body 122 and the contact body 123. The second transition section 126 smoothly connects the support body 122 and the contact body 123, and protrudes inward toward the movable contact 120. This allows for a smooth transition between the support body 122 and the contact body 123, avoiding sharp edges and stress concentration. Furthermore, the smooth second transition section 126 increases the flexibility and cushioning performance of the movable contact 120, preventing breakage.

[0125] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, along the first direction, the width of the end of the support body 122 connected to the mounting body 121 is greater than the width of the end of the support body 122 away from the mounting body 121. That is, the width of the top of the support body 122 is smaller than the width of the bottom of the support body 122. The support body 122 has a structure that is narrower at the top and wider at the bottom.

[0126] This improves the structural strength of the support body 122, maintains a certain width in the non-deformation concentration area of ​​the moving contact 120, thereby ensuring the overall structural strength and current carrying capacity of the moving contact 120. At the same time, it also improves the structural strength at the connection between the support body 122 and the mounting body 121, so that the support body 122 can reliably support the contact body 123, thereby improving the reliability of the moving contact 120.

[0127] It should be noted that the top of the support body 122 refers to the end where the support body 122 is connected to the contact body 123, and the bottom of the support body 122 refers to the end where the support body 122 is connected to the mounting body 121. Furthermore, the orientation of the top and bottom applies to the moving contact 120, the pushing assembly 100, and the relay 10, and will not be elaborated further below.

[0128] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the dimension of the support body 122 along the first direction gradually decreases from the end connected to the mounting body 121 to the end away from the mounting body 121. That is, the width of the support body 122 gradually increases from top to bottom, i.e., the width of the support body 122 is a gradually changing design. This improves the structural strength of the support body 122, avoids stress concentration caused by a protruding edge in the width dimension of the support body 122, and enhances the structural strength of the support body 122.

[0129] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the support body 122 has a first side 1221 and a second side 1222 opposite to each other along a first direction, wherein the first side 1221 and the second side 1222 are symmetrically inclined with respect to the central axis of the support body 122, or the first side 1221 is parallel to the central axis of the support body 122, and the second side 1222 is inclined with respect to the central axis of the support body 122 or is in a straight splicing type.

[0130] The two sides of the support body 122 along the first direction are the first side 1221 and the second side 1222, respectively. The distance between the first side 1221 and the second side 1222 changes along the height direction, so that the width of the end of the support body 122 connected to the mounting body 121 is greater than the width of the end of the support body 122 away from the mounting body 121, thereby improving the structural strength and support performance of the support body 122.

[0131] See Figures 3 to 5 , Figure 7 , Figure 8 In one embodiment of this application, the first side 1221 and the second side 1222 are symmetrically inclined with respect to the central axis of the support body 122. The distance between the first side 1221 and the second side 1222 gradually increases from top to bottom, so that the support body 122 has an approximately isosceles trapezoidal structure, thereby improving the structural strength and support performance of the support body 122.

[0132] See Figure 9 , Figure 10 and Figure 18 In one embodiment, in another embodiment of this application, the first side 1221 is parallel to the central axis of the support body 122, and the second side 1222 is inclined or in a straight splicing type relative to the central axis of the support body 122.

[0133] When the second side 1222 is inclined relative to the central axis of the support body 122, the support body 122 has a roughly right-angled trapezoidal structure. When the second side 1222 is a straight-line splicing type, the upper part of the second side 1222 has a recess to form an irregular edge. In this way, while improving the structural strength and support performance of the support body 122, the second side 1222 is recessed at the upper part relative to the lower part to accommodate the components of the relay 10.

[0134] Of course, in other embodiments, the support body 122 may also include multiple support segments of different widths, which are sequentially connected to form the support body 122. This also allows the support body 122 to support the contact body 123.

[0135] See Figures 3 to 5 , Figures 7 to 10 In one embodiment, along the second direction, the distance between the ends of the two support bodies 122 connected to the mounting body 121 is less than the distance between the ends of the two support bodies 122 away from the mounting body 121. That is, the distance between the tops of the two support bodies 122 is greater than the distance between their bottoms. Thus, the moving contact 120 has an overall trapezoidal structure, which increases its flexibility and cushioning performance, enabling reliable contact between the moving contact 120 and the stationary contact 200 and preventing stress concentration.

[0136] See Figures 2 to 10 In the first embodiment of this application, the moving contact 120 is characterized by a large width of the contact portion 1232 and a small width of the connecting portion 1231. Simultaneously, the supporting body 122 has a certain width, forming a structure with a large head, a thin neck, and a thick waist. This allows the moving contact 120 to resist stress concentration, preventing fatigue fracture caused by stress concentration. At the same time, it also prevents the supporting body 122 from deforming, ensuring overall structural strength and current-carrying capacity, and guaranteeing contact stability.

[0137] The above design of the moving contact 120 enables it to have sufficient flexibility and is not prone to breakage. It can also buffer vibration, enhance contact following and self-cleaning effect, while ensuring the structural strength of the moving contact 120 to ensure contact reliability, improve the fatigue life of the relay 10 under operating cycle, signal contact reliability and assembly processability.

[0138] See Figures 12 to 20 In the second embodiment of this application, the moving contact 120 has a U-shaped structure with flanges, and the moving contact 120 has a certain thickness to give it a certain rigidity, making it less prone to deformation and ensuring its structural strength and current carrying capacity. This allows the moving contact 120 to reliably contact the stationary contact 200 and provides vibration resistance to ensure the reliability of the relay 10's operation.

[0139] See Figure 7 and Figure 8 In one embodiment, the movable contact 120 is provided with a through hole 124. The through hole 124 is provided at one end of the support body 122 near the mounting body 121, at one end of the mounting body 121 near the support body 122, or simultaneously at both the mounting body 121 and the support body 122. That is, the bottom of the movable contact 120 is provided with a through hole 124, which further increases the flexibility of the bottom of the movable contact 120, achieving reliable contact while avoiding stress concentration.

[0140] See Figure 7 and Figure 8 In one embodiment, a through hole 124 is provided on both the support body 122 and the mounting body 121. That is, the through hole 124 is partially located at the bottom of the support body 122 and partially located at one end of the mounting body 121. In this way, the through hole 124 can increase the flexibility at the connection between the support body 122 and the mounting body 121, thereby increasing the flexibility at the bottom of the moving contact 120, achieving reliable contact while avoiding stress concentration.

[0141] Of course, in other embodiments, the through hole 124 may also be provided only in the support body 122 and located at the end of the support body 122 near the mounting body 121, or the through hole 124 may also be provided only in the mounting body 121 and located at the end of the mounting body 121 near the support body 122, which can also increase the flexibility of the bottom of the moving contact 120.

[0142] See Figure 7 and Figure 8In one embodiment, the through hole 124 is an elliptical hole or an oblong hole. It is understood that the shape of the through hole 124 is not limited in principle. In this embodiment, the through hole 124 is an oblong hole to increase the flexibility of the moving contact 120. Of course, in other embodiments, the through hole 124 can also be an elliptical hole or a hole of other shapes, as long as it can increase the flexibility of the moving contact 120 and avoid stress concentration.

[0143] See Figure 7 and Figure 8 In one embodiment, when the through hole 124 is provided on both the mounting body 121 and the support body 122, the extension length of the through hole 124 on the support body 122 is greater than the extension length on the mounting body 121. That is, the length of the through hole 124 on the support body 122 is greater than the length of the through hole 124 on the mounting body 121. This increases the flexibility at the connection between the support body 122 and the mounting body 121, thereby increasing the flexibility of the bottom of the moving contact 120, achieving reliable contact while avoiding stress concentration.

[0144] See Figures 2 to 10 In one embodiment, the push seat 110 and the moving contact 120 are integrally injection molded. Figure 6 for Figure 4 The diagram shows the push assembly 100 installed in the magnetic housing 400. After the moving contact 120 is placed in the injection mold, the material of the push seat 110 is injected into the injection mold. After the material solidifies, the push seat 110 and the moving contact 120 are integrated. At this time, the push seat 110 can partially cover the mounting body 121 of the moving contact 120 to achieve insulation isolation in the middle of the moving contact 120 and ensure the insulation effect.

[0145] In this way, the integrally injection-molded push seat 110 and moving contact 120 can improve the structural strength of the connection between the two, prevent the push seat 110 and moving contact 120 from separating, improve the reliability of the connection between the push seat 110 and moving contact 120, and also eliminate the gap between the push seat 110 and moving contact 120, thereby eliminating the loosening and error of the traditional assembly gap pulley, and ensuring the long-term consistency and reliability of the operation.

[0146] See Figure 5 , Figure 7 and Figure 10 In the first embodiment of this application, the mounting body 121 is provided with a connection hole 1211 configured for injection molding connection. The connection hole 1211 extends through the mounting body 121. During injection molding, the material of the push seat 110 can be filled into the connection hole 1211. Thus, after the push seat 110 and the moving contact 120 are formed, the push seat 110 can pass through the connection hole 1211 and cover part of the mounting body 121, improving the reliability of the connection between the push seat 110 and the moving contact 120.

[0147] See Figure 5 , Figure 7 and Figure 10 In one embodiment, the mounting body 121 is further provided with a first positioning hole 1212 and a second positioning hole 1213 configured for injection molding positioning. The first positioning hole 1212 and the second positioning hole 1213 are located on both sides of the connecting hole 1211. The first positioning hole 1212 and the second positioning hole 1213 are used to position the moving contact 120 in the injection mold to ensure that the moving contact 120 is reliably positioned in the injection mold and to prevent the position of the moving contact 120 from shifting, thereby ensuring the molding accuracy of the push seat 110 and the moving contact 120.

[0148] See Figure 5 , Figure 7 and Figure 10 In one embodiment, the first positioning hole 1212 and the second positioning hole 1213 have different shapes and / or sizes. That is, the first positioning hole 1212 and the second positioning hole 1213 can have different sizes, different shapes, or both different sizes and shapes. In this way, the first positioning hole 1212 and the second positioning hole 1213 can play a role in preventing mistaken positioning, preventing the moving contact 120 from being installed backwards in the injection mold, thereby avoiding the moving contact 120 being installed backwards relative to the push seat 110, and ensuring the accuracy of the molding of the moving contact 120 and the push seat 110.

[0149] See Figures 12 to 20 In the second embodiment of this application, the push assembly 100 further includes a compression spring 140, which is installed on the push seat 110 and located between the moving contact 120 and the push seat 110. The moving contact 120 is installed above the compression spring 140, thereby indirectly installed on the push seat 110. Figure 16 for Figure 14 The diagram shows the actuating assembly 100 mounted on the magnetic housing 400.

[0150] A compression spring 140 is positioned above the push base 110, and a moving contact 120 is located above the compression spring 140, allowing the moving contact 120 to be indirectly mounted on the push base 110. The moving contact 120 and the push base 110 are separate and independent structures, with the moving contact 120 elastically connected to the push base 110 via the compression spring 140. When the magnetic circuit assembly 500 drives the push base 110 to reciprocate along a third direction, the push base 110 drives the moving contact 120 to rise and fall synchronously via the compression spring 140, thereby enabling the moving contact 120 to connect or disconnect from the stationary contact 200.

[0151] The compression spring 140 serves as a buffer, shock absorber, and elastic compensation. Thus, when the pusher seat 110 pushes the contact 120 to contact the stationary contact 200, the compression spring 140 is compressed and deformed, preventing a rigid, hard impact between the moving and stationary contact parts. Simultaneously, the compression spring 140 provides stable elastic contact pressure, compensating for assembly gaps and machining tolerances, ensuring reliable contact between the moving contact 120 and the stationary contact 200, and improving contact stability.

[0152] See Figures 3 to 5 , Figures 7 to 10 , Figures 12 to 14 , Figure 17 and Figure 18 In one embodiment, the pushing assembly 100 includes a plurality of movable contacts 120, which are spaced apart and insulated from each other along a first direction and disposed on the pushing base 110. It should be noted that "a plurality" in this application refers to at least two. With the plurality of movable contacts 120 disposed on the pushing base 110, the pushing base 110 can achieve insulating isolation between the movable contacts 120, so that adjacent movable contacts 120 are mutually insulated.

[0153] Furthermore, each moving contact 120 corresponds to two stationary contacts 200, and correspondingly, multiple moving contacts 120 correspond to at least four stationary contacts 200. Each end of each moving contact 120 corresponds to a stationary contact 200, and the moving contact 120, the two stationary contacts 200, and the external circuit can form a conductive path.

[0154] When the pusher 110 simultaneously pushes at least two moving contacts 120 upwards in a third direction, both ends of each moving contact 120 contact with the corresponding stationary contact 200. Thus, after at least two moving contacts 120 contact with their corresponding stationary contacts 200, at least two conductive paths are formed. It should be noted that each moving contact 120 abuts against its mating stationary contact 200; that is, each stationary contact 200 only contacts its corresponding moving contact 120 and not the other stationary contacts 200.

[0155] In this way, at least two moving contacts 120 can contact at least four stationary contacts 200, thereby forming at least two electrically independent conductive paths, each of which can carry current. Thus, the relay 10 can carry current simultaneously through at least two conductive paths to meet the usage requirements of the relay 10 in different scenarios, and the at least two electrically independent conductive paths also serve the purpose of electrical redundancy.

[0156] In this embodiment, the pushing component 100 includes two moving contacts 120, which are spaced apart along a first direction. Correspondingly, the relay 10 includes four stationary contacts 200, with each moving contact 120 having one stationary contact 200 at each end. When the pushing seat 110 pushes the moving contact 120 into contact with the stationary contact 200, two different conductive paths can be formed. Of course, in other embodiments, the number of moving contacts 120 can be other, and the number of stationary contacts 200 can be adapted to the number of moving contacts 120.

[0157] See Figure 2 , Figure 4 , Figure 7 , Figure 12 In one embodiment, at least two moving contacts 120 are provided at an insulated distance from each other on the push base 110. This enables the two adjacent moving contacts 120 to be insulated from each other, thereby isolating at least two conductive paths from each other, effectively reducing flashover, leakage current and electromagnetic coupling between adjacent conductive paths, preventing crosstalk between the at least two conductive paths and improving the consistency and reliability of the relay 10's operation.

[0158] Optionally, the relay 10 of this application is a low-current relay, which can be connected to an external circuit simultaneously with a high-current relay. In this case, the low-current relay can monitor the high-current relay, thereby simultaneously realizing both power drive and logic control / monitoring functions. For example, the current of the low-current relay is 1A, and the current of the high-current relay is 120A. Of course, the currents of the low-current relay and the high-current relay can also be other values.

[0159] Furthermore, the number of moving contacts 120 in relay 10 is matched with the number of moving contacts in the high-current relay, so that the number of conductive paths in both is the same. Each conductive path in the low-current relay can monitor the conductive path of the high-current relay, thereby improving the reliability of relay 10 operation. For example, the low-current relay includes two moving contacts 120, and the high-current relay includes two moving contacts. Of course, the number of moving contacts 120 and the number of moving contacts can also be other.

[0160] See Figure 2 , Figure 4 , Figure 7 , Figure 12In one embodiment, the pushing assembly 100 further includes a push rod 130, which is disposed on the side of the pushing seat 110 opposite to the moving contact member 120 and extends out of the pushing seat 110 in a third direction. The push rod 130 is a component that connects the pushing assembly 100 to the magnetic circuit assembly 500. The push rod 130 is disposed below the pushing seat 110 and protrudes from the pushing seat 110. Furthermore, the push rod 130 can also pass through the magnetic housing 400 and connect to the magnetic circuit assembly 500.

[0161] In this way, the magnetic circuit assembly 500 can drive the push rod 130 to move in a third direction, and the push rod 130 can drive the push seat 110 to rise and fall in a third direction, thereby realizing the control of the relay 10 to be turned on or off. Optionally, the push rod 130 and the push seat 110 are an integral structure. Of course, in other embodiments, the push rod and the push seat 110 can also be set separately and reliably connected by interference fit, adhesive bonding or other methods.

[0162] See Figures 2 to 20 In one embodiment, the push seat 110 is configured to be movably mounted in the magnetic housing 400. The push seat 110 includes a main body 111 and a plurality of limiting portions 112. The plurality of limiting portions 112 are spaced apart on the periphery of the main body 111 and face the inner wall of the magnetic housing 400, for limiting the push seat 110 within the magnetic housing 400. The main body 111 is a structure for mounting the moving contact 120. The main body 111 is located in the magnetic housing 400 and can reciprocate in a third direction within the magnetic housing 400. The limiting portions 112 are components for positioning the push seat 110 within the magnetic housing 400.

[0163] Understandably, when the push base 110 reciprocates along a third direction within the magnetic housing 400, it is prone to deflection or tilting, which can cause the moving contact 120 to deviate from the stationary contact 200 during contact, affecting the stability and reliability of the relay 10. Therefore, this application provides multiple limiting parts 112 around the periphery of the main body base 111 to limit the movement of the push base 110 relative to the magnetic housing 400.

[0164] Specifically, multiple limiting parts 112 are spaced apart on the periphery of the main body 111 and protrude outwards. Here, the periphery of the main body 111 refers to the four surrounding surfaces of the main body 111, which are also the surfaces of the main body 111 opposite to the inner wall of the magnetic housing 400. Thus, after the push seat 110 is placed in the magnetic housing 400, the limiting parts 112 can extend towards the inner wall of the magnetic housing 400 and cooperate with the magnetic housing 400 to limit the push seat 110 within the magnetic housing 400.

[0165] When the push base 110 moves normally in a straight line within the magnetic housing 400, it maintains a gap and does not contact the inner wall of the magnetic housing 400 to avoid motion interference. When the push base 110 tends to deflect or tilt during reciprocating motion within the magnetic housing 400, the limiting part 112 can abut against the inner wall of the magnetic housing 400, restricting the deflection or tilt of the push base 110 relative to the magnetic housing 400. This ensures that the push base 110 can only move in a third direction relative to the magnetic housing 400 and cannot deflect relative to the magnetic housing 400, preventing the push base 110 from deflecting or tilting under long-term high-frequency operation of the relay 10 or external vibration interference, thereby ensuring that the push base 110 always moves in a straight line along a preset trajectory. This structure can avoid contact offset and poor contact caused by long-term high-frequency operation or external vibration, reduce mechanical wear and noise caused by shaking, and improve the switch's vibration resistance, mechanical life, and operational reliability.

[0166] Furthermore, when the push base 110 moves along a third direction within the magnetic housing 400, the limiting part 112 will not contact the inner wall of the magnetic housing 400, so that the push base 110 moves stably along the third direction, avoiding interference from the magnetic housing 400 on the movement of the push base 110 along the third direction, thereby ensuring that the push base 110 can stably drive the driving contact 120 to rise or fall, and ensuring the stability and reliability of the relay 10 operation.

[0167] Furthermore, after the limiting part 112 limits the push seat 110, it can also prevent the push seat 110 from deflecting or moving, thus reducing the eccentric torque that the push seat 110 is subjected to and cannot move smoothly in the preset straight direction. Moreover, compared with the method of limiting the push seat 110 by having the entire outer wall surface of the push seat 110 contact the inner wall of the magnetic housing 400, the method of limiting the push seat 110 by the limiting part 112 has the characteristics of low frictional resistance and smooth movement.

[0168] For example, multiple limiting portions 112 protrude from both sides of the main body 111 along the first direction, and thus the multiple limiting portions 112 correspond to the inner walls of the magnetic housing 400 along the first direction, and cooperate with the corresponding inner walls of the magnetic housing 400 for limiting. When the push seat 110 tends to tilt or deflect in the magnetic housing 400, the limiting portions 112 can abut against the inner walls of the magnetic housing 400 along the first direction, thereby limiting the push seat 110 in the magnetic housing 400. Of course, in other embodiments, the multiple limiting portions 112 may also protrude from other surfaces of the main body 111.

[0169] Thus, when the push seat 110 of this application moves normally up and down in a third direction within the magnetic housing 400, the limiting part 112 will not abut against the inner wall of the magnetic housing 400. At the same time, once the push seat 110 tilts or deflects within the magnetic housing 400, the limiting part 112 will abut against the inner wall of the magnetic housing 400 to limit the deflection or tilting of the push seat 110 within the magnetic housing 400. The limiting part 112 ensures the accuracy of the push seat 110's positioning within the magnetic housing 400.

[0170] In this way, the limiting part 112 ensures that the push seat 110 can only move relative to the magnetic housing 400 and cannot deflect relative to the magnetic housing 400. This prevents the push seat 110 from deflecting or tilting under long-term high-frequency operation of the relay 10 or external vibration interference, thus ensuring that the push seat 110 always moves linearly along the preset trajectory. This not only avoids the problem of contact position displacement or poor contact caused by the rotation of the push seat 110, but also eliminates the additional mechanical wear and noise caused by shaking. At the same time, it helps to maintain the contact gap and overtravel of the relay 10 constant, improving the vibration resistance, mechanical life and contact operation reliability of the relay 10.

[0171] Furthermore, when at least two elastic members 110 are installed on the push base 110, if the push base 110 shifts or moves, it can easily cause at least two moving contacts 120 to come into contact or to come into contact with a non-corresponding stationary contact 200. This application, by limiting the push base 110 with the limiting part 112, can prevent at least two moving contacts 120 from coming into contact or to come into contact with a non-corresponding stationary contact 200, thereby improving the reliability and stability of the relay 10's operation, preventing the relay 10 from generating erroneous monitoring signals, and improving the accuracy of the information.

[0172] See Figures 3 to 10 , Figures 15 to 20 In one embodiment, the limiting portion 112 protrudes from the outer peripheral surface of the main body 111 along a first direction. That is, the limiting portion 112 protrudes from the surface of the main body 111 along the first direction. Thus, multiple limiting portions 112 protrude from both sides of the main body 111 along the first direction, and consequently, these multiple limiting portions 112 correspond to the inner walls of the magnetic housing 400 along the first direction, and cooperate with the corresponding inner walls of the magnetic housing 400 for limiting. When the push seat 110 tends to tilt or deflect within the magnetic housing 400, the limiting portion 112 can abut against the inner wall of the magnetic housing 400 along the first direction, thereby limiting the push seat 110 within the magnetic housing 400.

[0173] See Figures 3 to 10 , Figures 15 to 20In one embodiment, a predetermined gap exists between the limiting part 112 and the inner wall of the magnetic housing 400 along a first direction. After the push seat 110 is installed on the magnetic housing 400, a certain gap exists between the end of the limiting part 112 and the inner wall of the magnetic housing 400. Thus, when the magnetic circuit assembly 500 drives the push seat 110 to move the moving contact 120 upward or downward along a third direction, because there is a gap between the limiting part 112 and the inner wall of the magnetic housing 400, the limiting part 112 will not contact the inner wall of the magnetic housing 400. Consequently, the magnetic housing 400 will not interfere with the movement of the push seat 110, ensuring the smoothness of the movement of the push seat 110. This facilitates the push seat 110 to drive the moving contact 120 to contact or separate from the stationary contact 200, improving the stability and reliability of the relay 10's operation.

[0174] In one embodiment, the push base 110 includes four limiting portions 112, with two limiting portions 112 provided on each end face of the main body base 111, and the two limiting portions 112 are symmetrically arranged. The four limiting portions 112 are provided in the corner regions of the main body base 111, and the four limiting portions 112 are symmetrically arranged with respect to the central axis of the main body base 111 along a first direction. That is, the two symmetrical limiting portions 112 protrude from the main body base 111 in opposite directions.

[0175] For example, four limiting portions 112 protrude from two surfaces of the main body 111 along the first direction, and thus the four limiting portions 112 correspond to the inner wall of the magnetic housing 400 along the first direction. When the push seat 110 tilts or deflects in the magnetic housing 400, the limiting portions 112 can abut against the inner wall of the magnetic housing 400 along the first direction, thereby limiting the push seat 110 in the magnetic housing 400.

[0176] Furthermore, the four limiting parts 112 are symmetrically arranged behind the main body 111. The four limiting parts 112 can achieve bidirectional limiting of the push seat 110 in the clockwise and counterclockwise directions. No matter which direction the push seat 110 deflects or tilts, there is a corresponding limiting part 112 to limit the push seat 110.

[0177] In another embodiment, the number of limiting parts 112 may also be two, with the two limiting parts 112 disposed opposite to each other on the two end faces of the main body 111 along the first direction. In this way, the two limiting parts 112 can limit the push seat 110 at one end. Of course, in other embodiments, the number of limiting parts 112 can be adjusted as needed, such as six or other numbers.

[0178] See Figures 3 to 10 , Figures 15 to 20In one embodiment, the main body 111 and the limiting part 112 are integrally injection molded. That is, the main body 111 and the limiting part 112 can be integrally molded by injection molding. This simplifies the molding and assembly processes of the main body 111 and the limiting part 112, while ensuring the structural strength of the connection between the main body 111 and the limiting part 112, thereby improving the structural strength and overall reliability of the push seat 110.

[0179] See Figure 4 , Figure 7 , Figure 9 , Figure 15 , Figures 17 to 19 In one embodiment, the limiting portion 112 includes a support arm 1121 and a limiting protrusion 1122. The support arm 1121 is connected to the end face of the main body 111 and extends along the second direction. The limiting protrusion 1122 protrudes from the surface of the support arm 1121 facing the inner wall of the guide magnet housing 400. The end face of the main body 111 refers to the surface of the main body 111 facing each other along the second direction. The support arm 1121 is a component that supports the limiting protrusion 1122.

[0180] A limiting protrusion 1122 is disposed at the end of the support arm 1121 away from the main body 111 and is located on the outer surface of the support arm 1121, that is, the limiting protrusion 1122 is located on the surface of the support arm 1121 facing the magnetic housing 400. After the support arm 1121 is connected to the end face of the main body 111, the support arm 1121 extends along the second direction and also extends along the first direction. In this way, the limiting protrusion 1122 can at least partially protrude from the surface of the main body 111 along the first direction, so that there is a predetermined gap between the limiting protrusion 1122 and the inner wall of the magnetic housing 400.

[0181] Thus, when the magnetic circuit assembly 500 drives the push base 110 to move the moving contact 120 upward or downward in a third direction, because there is a gap between the limiting protrusion 1122 and the inner wall of the magnetic housing 400, the limiting protrusion 1122 will not contact the inner wall of the magnetic housing 400. Consequently, the magnetic housing 400 will not interfere with the movement of the push base 110, ensuring the smoothness of the movement of the push base 110. This facilitates the push base 110 to drive the moving contact 120 to contact or separate from the stationary contact 200, thereby improving the stability and reliability of the relay 10's operation.

[0182] Furthermore, once the push seat 110 deflects or tilts, the protruding limiting protrusion 1122 can abut against the inner wall of the magnetic housing 400, limiting the deflection or tilt of the push seat 110, so as to ensure that the push seat 110 is reliably positioned in the magnetic housing 400, avoiding the problem of contact position offset or poor contact caused by the rotation of the push seat 110, and also eliminating the additional mechanical wear and noise caused by shaking, improving the vibration resistance, mechanical life and contact action reliability of the relay 10.

[0183] It should be noted that the structural form of the support arm 1121 is not limited in principle, as long as the support arm 1121 can support the limiting protrusion 1122 on the main body 111. Optionally, the support arm 1121 can be plate-shaped, column-shaped, or other shapes. In other embodiments, the support arm 1121 can also be a frame structure, etc. Of course, the support arm 1121 can also be omitted, and the limiting protrusion 1122 can be directly provided on the main body 111.

[0184] See Figure 4 , Figure 7 , Figure 9 , Figure 15 , Figures 17 to 19 In one embodiment, the support arm 1121 and the limiting protrusion 1122 are integrally injection molded. That is, the support arm 1121 and the limiting protrusion 1122 are integrally molded by injection molding. This simplifies the molding and assembly processes of the support arm 1121 and the limiting protrusion 1122, while also ensuring the structural strength of the connection between the support arm 1121 and the limiting protrusion 1122.

[0185] See Figure 4 , Figure 7 , Figure 9 , Figure 15 , Figures 17 to 19 In one embodiment, the dimension of the support arm 1121 along the first direction gradually decreases from the end near the main body 111 to the end away from the main body 111. That is, the width of the support arm 1121 is gradually reduced. In this way, the flexibility of the support arm 1121 can be increased without affecting the structural strength of the support arm 1121, thereby reducing hard impacts and wear, so as to reliably support the limiting protrusion 1122 and facilitate the positioning of the pushing seat 110 by the limiting protrusion 1122.

[0186] See Figure 4 , Figure 7 , Figure 9 , Figure 15 , Figures 17 to 19 In one embodiment, the dimension of the support arm 1121 in a third direction gradually decreases from the end closer to the main body 111 to the end farther away from the main body 111. That is, the thickness of the support arm 1121 is gradually reduced. In this way, the flexibility of the support arm 1121 can be increased without affecting the structural strength of the support arm 1121, so as to reliably support the limiting protrusion 1122 and facilitate the positioning of the pushing seat 110 by the limiting protrusion 1122.

[0187] See Figure 4 , Figure 7 , Figure 9 , Figure 15 , Figures 17 to 19In one embodiment, the outer peripheral surface of the limiting protrusion 1122 is arc-shaped. That is, the limiting protrusion 1122 has a cylindrical or hemispherical structure. This facilitates the contact between the limiting protrusion 1122 and the inner wall of the magnetic housing 400, and avoids interference between the limiting protrusion 1122 and the magnetic housing 400, thereby reducing friction and lowering the risk of jamming. Of course, in other embodiments, the limiting protrusion 1122 may also have a rib structure, as long as it can cooperate with the magnetic housing 400 to limit the movement of the push seat 110.

[0188] See Figures 2 to 10 In the first embodiment of this application, the main body 111 includes a first seat 1111 and a second seat 1112. The first seat 1111 supports the moving contact 120. The first seat 1111 is located on the side of the second seat 1112 facing the moving contact 120, and the limiting part 112 is located on the second seat 1112. This application divides the main body 111 into the first seat 1111 and the second seat 1112 along a third direction. The moving contact 120 is partially located in the first seat 1111, and the limiting part 112 is located on the side of the second seat 1112. This increases the insulation distance between the moving contact 120 and the limiting part 112, thereby increasing the creepage distance of the moving contact 120 and ensuring the insulation effect of the relay 10.

[0189] See Figures 2 to 10 In one embodiment, the first base 1111 and the second base 1112 are an integral structure. That is, the first base 1111 and the second base 1112 are molded as a single piece by injection molding. This simplifies the molding and assembly process of the main body 111, while also ensuring the structural strength at the connection between the first base 1111 and the second base 1112, thereby ensuring the overall structural strength of the main body 111.

[0190] See Figures 2 to 10 In one embodiment, the dimension of the first seat 1111 along a third direction is smaller than the dimension of the second seat 1112 along a third direction. This ensures insulation performance between the moving contacts 120 while maintaining the creepage distance of the moving contacts 120, and reduces the overall thickness and weight of the main seat 111, facilitating the movement of the moving contacts 120 within the magnetic housing 400 by the push seat 110. Of course, in other embodiments, the thickness relationship between the first seat 1111 and the second seat 1112 can be different.

[0191] See Figures 2 to 10In one embodiment, the outer peripheral surface of the first seat 1111 protrudes beyond the outer peripheral surface of the second seat 1112. That is, after the first seat 1111 is disposed on the second seat 1112, the first seat 1111 forms an insulating protrusion on the second seat 1112. Thus, the protruding first seat 1111 can serve as an insulating barrier, increasing the creepage distance of the moving contact 120 and further improving the insulation performance of the relay 10.

[0192] See Figures 2 to 10 In one embodiment, the limiting part 112 and the first base 1111 are spaced apart in a third direction by a predetermined distance. In this way, the limiting part 112 can maintain a certain distance from the moving contact 120 on the first base 1111 in the third direction, thereby increasing the creepage distance of the moving contact 120 and further improving the insulation performance of the relay 10.

[0193] See Figure 9 and Figure 10 In one embodiment, the surface of the main body 111 facing the stationary contact member 200 has a first mating hole 1117 and a second mating hole 1118. The first mating hole 1117 is correspondingly disposed with a first positioning hole 1212 on the moving contact member 120, and the second mating hole 1118 is correspondingly disposed with a second positioning hole 1213 on the moving contact member 120. The first mating hole 1117 and the first positioning hole 1212 are coaxially disposed and communicate with each other, and the second mating hole 1118 and the second positioning hole 1213 are coaxially disposed and communicate with each other.

[0194] The first mating hole 1117 and the second mating hole 1118 are holes formed by the positioning of the moving contact 120 during the injection molding process. After the moving contact 120 is placed in the injection mold, the first positioning rod on the injection mold can extend into the first positioning hole 1212 and the second positioning hole 1213 on the moving contact 120 to achieve accurate positioning of the moving contact 120.

[0195] Subsequently, the material required for the push seat 110 is fed into the injection mold, during which the material bypasses the first positioning rod. After the material solidifies to form the push seat 110, the injection mold removes the first positioning rod. At this time, the first positioning rod forms a first mating hole 1117 and a second mating hole 1118 on the push seat 110, and the first mating hole 1117 is connected to the first positioning hole 1212, and the second mating hole 1118 is connected to the second positioning hole 1213.

[0196] Thus, the first mating hole 1117 and the second mating hole 1118 can achieve accurate positioning of the push seat 110 and the moving contact 120, which not only facilitates the positioning and forming of the push seat 110 and the moving contact 120, but also reduces the weight of the push seat 110. Furthermore, the shape and size of the first mating hole 1117 are adapted to the shape and size of the first positioning hole 1212, and the shape and size of the second mating hole 1118 are adapted to the shape and size of the second positioning hole 1213.

[0197] See Figure 9 In one embodiment, the surface of the main body 111 facing the stationary contact 200 also has a plurality of third mating holes 1119. The plurality of third mating holes 1119 are spaced apart along a first direction and a second direction. The third mating holes 1119 are configured to position the moving contact 120 during injection molding of the push assembly 100. The third mating holes 1119 extend through the main body 111 to the moving contact 120 along a third direction.

[0198] After the moving contact 120 is placed in the injection mold, the injection mold also has multiple second positioning rods. These multiple second positioning rods can abut against the upper surface of the moving contact 120 to reliably fix the moving contact 120, prevent the moving contact 120 from shifting in position in the injection mold, ensure the positioning accuracy of the moving contact 120 relative to the main body seat 111, and thus ensure that the moving contact 120 can reliably cooperate with the stationary contact 200.

[0199] The material required for the push seat 110 is fed into the injection mold, during which the material bypasses the second positioning rod. After the material solidifies to form the push seat 110, the injection mold removes the second positioning rod. At this point, multiple second positioning rods can form multiple third mating holes 1119 on the push seat 110. This ensures that the moving contact 120 is accurately positioned during injection molding.

[0200] Furthermore, multiple third mating holes 1119 are arranged in rows and columns on the upper surface of the main body 111, so that the main body 111 is hollowed out. This reduces the overall weight of the push seat 110, making it easier for the magnetic circuit assembly 500 to drive the push seat 110 to rise or fall in a third direction. This facilitates the magnetic circuit assembly 500 to drive the push seat 110 to move in a third direction, thereby improving the stability and reliability of the relay 10's operation.

[0201] Understandably, the shape of the third mating hole 1119 is not limited in principle, as long as it can achieve the positioning of the moving contact 120. Optionally, the shapes and sizes of multiple third mating holes 1119 can be the same or different. Furthermore, the distances between adjacent third mating holes 1119 can be equal or unequal.

[0202] See Figure 9In one embodiment, the side of the main body 111 is provided with a fourth mating hole 11101 communicating with the third mating hole 1119. The fourth mating hole 11101 is configured to position the moving contact 120 during injection molding of the pushing assembly 100. That is, the side of the main body 111 along the first direction is also provided with a fourth mating hole 11101, which extends from the main body 111 along the first direction to the moving contact 120.

[0203] After the moving contact 120 is placed in the injection mold, the injection mold also has multiple third positioning rods. These multiple third positioning rods can abut against the side of the moving contact 120 to reliably fix the moving contact 120, prevent the moving contact 120 from shifting in position in the injection mold, ensure the positioning accuracy of the moving contact 120 relative to the main body seat 111, and thus ensure that the moving contact 120 can reliably cooperate with the stationary contact 200.

[0204] The material required for the push seat 110 is fed into the injection mold, during which the material bypasses the third positioning rod. After the material solidifies to form the push seat 110, the injection mold removes the third positioning rod. At this point, multiple third positioning rods can form a fourth mating hole 11101 on the push seat 110. This ensures that the moving contact 120 is accurately positioned during injection molding.

[0205] Furthermore, the fourth mating holes 11101 are arranged in rows and columns on the side of the main body 111, which reduces the overall weight of the push seat 110 and makes it easier for the magnetic circuit assembly 500 to drive the push seat 110 to rise or fall in a third direction. Optionally, the number of fourth mating holes 11101 on one side of the main body 111 may be one or more.

[0206] See Figure 9 In one embodiment, the main body 111 further includes an isolation space 11102. The isolation space 11102 extends along a second direction and is located at both ends of the main body 111 along the second direction. The isolation space 11102 also penetrates the main body 111 along a third direction and is located between two adjacent moving contacts 120. The isolation space 11102 is a recess in the main body 111 along the second direction. The isolation space 11102 is located on the surface of the main body 111 along the second direction and is disposed through the third direction.

[0207] Furthermore, the isolation space 11102 is located between two adjacent moving contacts 120, and the main body 111 is provided with isolation spaces 11102 on both sides along the second direction. In this way, the isolation space 11102 can form an isolation path between two adjacent moving contacts 120, increase the creepage distance of the two moving contacts 120, realize the insulation isolation of the two moving contacts 120, ensure the insulation effect of the moving contacts 120, and thus ensure the insulation effect of the relay 10.

[0208] In this embodiment, there are two isolation spaces 11102, which are disposed at both ends of the main body 111 along the second direction to isolate the two moving contacts 120. Of course, in other embodiments, the number of isolation spaces 11102 can be other, as long as it can achieve insulation isolation between two adjacent moving contacts 120. It should be noted that the dimensions of the isolation space 11102 along the first direction and the depth along the second direction are not limited in principle, as long as the insulation effect is guaranteed and the structural strength of the push base 110 is not affected.

[0209] See Figures 13 to 20 In the second embodiment of this application, the main body 111 includes a third seat 1113, which supports the compression spring 140. A limiting part 112 is provided on the side of the third seat 1113 away from the compression spring 140. The compression spring 140 is disposed on the upper surface of the third seat 1113, and the push rod 130 is disposed below the third seat 1113 and extends out of the third seat 1113.

[0210] The limiting part 112 is disposed on the outer peripheral surface of the third seat 1113 and has a certain distance between it and the compression spring 140. After the push seat 110 is installed on the magnetic housing 400, the limiting part 112 faces the inner wall of the magnetic housing 400 to limit the push seat 110. Optionally, the limiting part 112 is disposed at the bottom of the third seat 1113 and protrudes from the bottom of the third seat 1113. Of course, in other embodiments, the limiting part 112 may at least partially overlap with the projection of the third seat 1113 in a third direction.

[0211] It should be noted that the third seat 1113 in this embodiment can be adapted to the requirements of the moving contact 120 in the second embodiment, so that the moving contact 120 can be installed on the push seat 110 via the compression spring 140, and at the same time, the moving contact 120 can be stably supported. Of course, in other embodiments, the moving contact 120 in the first embodiment can also be directly installed on the third seat 1113.

[0212] See Figure 15 , Figure 16 , Figures 18 to 20 In one embodiment, the surface of the third seat 1113 is further provided with a separating member 11131, which extends along a second direction and is configured to separate two adjacent compression springs 140. The separating member 11131 protrudes from the upper surface of the third seat 1113, and the two adjacent compression springs 140 are located on both sides of the separating member 11131 along a first direction.

[0213] Thus, the isolation component 11131 can achieve at least partial isolation between two adjacent compression springs 140, which can extend the insulation path between two adjacent conductive paths, increase the creepage distance, and achieve reliable insulation between conductive paths. In this embodiment, there are two compression springs 140, and one isolation component 11131 is provided on the third base 1113 to provide insulation isolation between the two compression springs 140. Of course, in other embodiments, the number of isolation components 11131 and compression springs 140 can also be different.

[0214] Optionally, the isolation member 11131 is plate-shaped, so that there is a certain distance between the isolation member 11131 and the compression spring 140, avoiding interference between the isolation member 11131 and the compression spring 140, and ensuring the smooth movement of the moving contact member 120. Of course, in other embodiments, the isolation member 11131 may also be a block-shaped protrusion or other regular or irregular protrusions, as long as the isolation member 11131 does not contact the compression spring 140 and can play an insulating role.

[0215] See Figure 15 , Figure 16 , Figures 18 to 20 In one embodiment, the dimension of the isolation member 11131 along a third direction is smaller than the dimension of the compression spring 140 along a third direction. It is understood that when the push seat 110 drives the moving contact 120 to contact the stationary contact 200 via the compression spring 140, the moving contact 120 will press down on the compression spring 140. By defining the height relationship between the isolation member 11131 and the compression spring 140, this application can prevent interference between the isolation member 11131 and the components between the two moving contacts 120.

[0216] In this embodiment, the dimension of the isolation member 11131 along the third direction is 1 / 5 to 2 / 3 of the dimension of the compression spring 140 along the third direction. This prevents interference between the isolation member 11131 and the components between the two moving contacts 120 when the moving contact 120 compresses the compression spring 140. Of course, in other embodiments, the dimension of the isolation member 11131 along the third direction can be other dimensions, as long as interference between the isolation member 11131 and the components between the two moving contacts 120 is avoided.

[0217] See Figure 14 , Figure 15 , Figure 19 and Figure 20 In one embodiment, the surface of the third seat 1113 is further provided with a support platform 11133, which is used to support the compression spring 140. The edge of the support platform 11133 is provided with an inclined support edge, which abuts against the compression spring 140.

[0218] The support platform 11133 supports the installation of the compression spring 140, raising its assembly height and increasing the distance between the moving contact 120 and the surface of the third base 1113. This facilitates heat dissipation, reduces temperature rise, and improves the operational stability of the relay 10. Furthermore, the support platform 11133 provides a flat and stable mounting reference surface for the moving contact 120, enabling rapid determination of the installation position, improving assembly efficiency, and preventing poor contact between the moving contact 120 and the stationary contact 200 caused by tilting during installation.

[0219] Furthermore, the bottom of the compression spring 140 can also abut against the inclined support edge of the support platform 11133. In this way, when the moving contact 120 contacts the stationary contact 200, the moving contact 120 can press down on the compression spring 140 so that the support edge supports the compression spring 140, preventing the compression spring 140 from shaking and ensuring the stability of the contact.

[0220] See Figure 14 , Figure 15 , Figure 19 and Figure 20 In one embodiment, the surface of the third seat 1113 is further provided with a positioning protrusion 11132, which protrudes from the support platform 11133 and is configured to mount the compression spring 140. The positioning protrusion 11132 protrudes from the upper surface of the third seat 1113, and the compression spring 140 is provided with a positioning hole corresponding to the positioning protrusion 11132. When the compression spring 140 is installed on the push seat 110, the positioning hole of the compression spring 140 can be fitted into the positioning protrusion 11132, so that the compression spring 140 can be positioned and installed on the third seat 1113.

[0221] The positioning protrusion 11132 enables the accurate positioning of the compression spring 140, allowing it to be accurately installed onto the third base 1113. This, in turn, ensures the accurate installation of the moving contact 120 onto the third base 1113, preventing the compression spring 140 from shifting relative to the third base 1113. Consequently, it guarantees stable contact between the moving contact 120 and the stationary contact 200, thus ensuring the reliability and stability of the relay 10's operation.

[0222] See Figure 14 , Figure 15 , Figure 19 and Figure 20 In one embodiment, the third seat 1113 is provided with two positioning protrusions 11132, the outer diameters and / or shapes of the two positioning protrusions 11132 being different. The two positioning protrusions 11132 are spaced apart above the third seat 1113 along a second direction. Correspondingly, the compression spring 140 is provided with two positioning holes corresponding to the positioning protrusions 11132, the outer diameters and / or shapes of the two positioning protrusions 11132 being adapted to the positioning holes.

[0223] In other words, the two positioning protrusions 11132 can have different outer diameters, different shapes, or both different outer diameters and shapes. In this way, the cooperation between the two positioning protrusions 11132 and the two positioning holes can play a foolproof role, preventing the compression spring 140 from being installed backwards in the third seat 1113, so as to ensure that the position of the compression spring 140 relative to the push seat 110 and the moving contact 120 is accurate, and that the compression spring 140 accurately buffers the moving contact 120.

[0224] See Figure 20 In one embodiment, the surface of the support platform 11133 is provided with a first groove 111331 and a second groove 111332. The first groove 111331 and the second groove 111332 are spaced apart along a first direction and at least partially offset along a second direction. The first groove 111331 and the second groove 111332 are process holes for integral injection molding to facilitate the injection molding of the push seat 110.

[0225] See Figures 13 to 17 In one embodiment, the main body 111 further includes two support members 1114, which are disposed opposite to each other on the third seat 1113 along a first direction and protrude from the surface of the third seat 1113. A limiting portion 112 is disposed on the side of the third seat 1113 away from the support members 1114. The third seat 1113 and the two support members 1114 are configured to accommodate a compression spring 140 and a portion of the moving contact member 120. Optionally, the support members 1114 are plate-shaped.

[0226] Support member 1114 is located at the edge of third base 1113, and the two support members 1114 and third base 1113 can be configured into a U-shaped structure. Compression spring 140 is located in the space between the two support members 1114, and moving contact 120 is partially located in the space between the two support members 1114. In this way, the two support members 1114 can form an insulating barrier on both sides of compression spring 140 in a third direction, thereby increasing the creepage distance and ensuring the insulation effect of relay 10.

[0227] See Figures 13 to 17 In one embodiment, the main body 111 further includes a partition protrusion 1116, which protrudes from the inner wall of the support member 1114. The partition protrusion 1116 is located at the edge of the inner wall of the support member 1114 and protrudes outward. Furthermore, the partition protrusions 1116 on both support members 1114 extend towards the center of the U-shape. In this way, the partition protrusion 1116 can increase the structural strength of the main body 111, and at the same time, the partition protrusion 1116 can also form a barrier on the side of the main body 111 to form an insulating barrier.

[0228] See Figures 13 to 17In one embodiment, the inner wall of the support member 1114 is provided with a plurality of partition protrusions 1116, which are spaced apart along the second direction. That is, the support member 1114 is provided with a plurality of partition protrusions 1116 along one side edge of the second direction. In this way, the plurality of partition protrusions 1116 can increase the structural strength of the main body 111, and at the same time, the plurality of partition protrusions 1116 can also form a barrier on the side of the main body 111, further increasing the creepage distance.

[0229] See Figure 17 In one embodiment, the separating protrusion 1116 has a vertical plate-like structure. See also... Figures 13 to 15 In another embodiment, the partition protrusion 1116 may also be trapezoidal. Optionally, the third seat 1113, the support member 1114, and the partition protrusion 1116 are integrally injection molded. This simplifies the assembly process and improves the structural strength of the main seat 111.

[0230] See Figures 13 to 17 In one embodiment, the inner walls of the support member 1114 at both ends along the second direction are respectively provided with partition protrusions 1116. In this way, the partition protrusions 1116 can form barriers on both sides of the support member 1114 along the second direction to increase the insulation path and thus increase the creepage distance.

[0231] See Figures 17 to 20 In one embodiment, the main body 111 further includes a limiting stop 1115, which protrudes from the edge of the third body 1113. The limiting stops 1115 are spaced apart along the second direction and located at the edge of the third body 1113. The limiting stops 1115 can form blocks at both ends of the third body 1113 along the second direction to increase the insulation path and thus increase the creepage distance.

[0232] See Figures 18 to 20 In one embodiment, there are two limiting stops 1115, which are disposed along the second direction on the edge of the third seat 1113. (See also...) Figure 17 In another embodiment, the number of limiting edges 1115 may be at least four, and the at least four limiting edges 1115 are respectively disposed along the second direction on the edge of the third seat 1113, and adjacent limiting edges 1115 are spaced apart to increase the insulation path.

[0233] It should be noted that in the second embodiment of this application, the main body 111 may only include the third seat body 1113. Of course, in addition to the third seat body 1113, the main body 111 may also include at least one of the supporting member 1114 and the limiting stop 1115 to form different types of main bodies 111, as long as the structural strength of the main body 111 can be guaranteed and the compression spring 140 and the moving contact member 120 can be stably supported.

[0234] See Figure 17 In the first variation of this application, the main body 111 includes a third seat 1113, a support member 1114, and a limiting stop 1115. The inner wall of the edge of the support member 1114 is provided with a partition protrusion 1116. Furthermore, the number of both the partition protrusion 1116 and the limiting stop 1115 on one edge of the support member 1114 is at least two, and the partition protrusion 1116 is connected to the limiting stop 1115. This allows for multiple barriers to be provided at the edge of the main body 111, increasing the creepage distance.

[0235] See Figures 18 to 20 In the second modification, the main body 111 includes a third seat body 1113 and a limiting stop 1115, with the limiting stop 1115 located at the edge of the third seat body 1113 along the second direction. Thus, the limiting stop 1115 can act as a barrier at the edge to form insulation, while also simplifying the structure of the push seat 110, reducing the molding difficulty of the push seat 110, and facilitating injection molding of the push seat 110.

[0236] See Figures 12 to 14 , Figures 16 to 18 In one embodiment, the actuating assembly 100 further includes an insulating member 150 disposed in the central region of the plurality of moving contacts 120 and configured to insulate the plurality of moving contacts 120. The insulating member 150 covers the central region of the moving contacts 120, thereby providing insulation between adjacent moving contacts 120 and preventing short circuits between adjacent moving contacts 120.

[0237] See Figures 12 to 14 , Figures 16 to 18 In one embodiment, the insulating member 150 includes an insulating body 151 and two insulating barriers 152. The insulating body 151 covers the central region of the moving contact 120, and the two insulating barriers 152 are disposed opposite to each other at both ends of the insulating body 151 and protrude from the outer wall of the insulating body 151. Optionally, the insulating body 151 and the two insulating barriers 152 are injection molded in the central region of the moving contact 120.

[0238] The insulating body 151 is a component that provides insulation between two moving contacts 120. The insulating body 151 covers the central region of the moving contacts 120 to insulate adjacent moving contacts 120. Insulating barriers 152 are disposed at both ends of the insulating body 151 along a second direction and protrude from each other. Thus, the insulating barriers 152 can act as barriers at both ends of the insulating body 151 to increase the creepage distance.

[0239] See Figures 12 to 14 , Figure 16 In one embodiment, the insulating element 150 at least partially covers the mounting body 121. That is, the insulating element 150 may cover part or all of the mounting body 121. In this embodiment, the insulating element 150 covering part of the mounting body 121 can reduce costs while achieving insulation isolation between the two moving contacts 120.

[0240] See Figure 17 In another embodiment, the insulating element 150 covers the mounting body 121 and part of the support body 122. That is, the insulating element 150 securely covers the mounting body 121, and the insulating element 150 also extends to the support body 122 to cover the bottom of the support body 122. This increases the insulation path of the two moving contacts 120, thereby increasing the creepage distance and ensuring the insulation effect.

[0241] See Figures 12 to 14 , Figures 16 to 18 In one embodiment, each insulating element 150 corresponds to one moving contact 120. That is, the pushing assembly 100 includes a plurality of insulating elements 150, and the insulating elements 150 and the moving contacts 120 are arranged in a one-to-one correspondence. In this way, the plurality of insulating elements 150 can achieve insulation isolation between the plurality of moving contacts 120, ensuring the insulation effect.

[0242] Of course, in other embodiments, the insulating member 150 simultaneously covers the central region of the plurality of moving contacts 120. That is, after the plurality of moving contacts 120 are spaced apart, injection molding is performed on the central region of the plurality of moving contacts 120 to form an integral insulating member 150. At this time, the insulating member 150 simultaneously connects the plurality of moving contacts 120 and achieves insulation isolation between the plurality of moving contacts 120, ensuring the insulation effect.

[0243] See Figures 12 to 14 , Figures 16 to 18In one embodiment, the pushing assembly 100 further includes a bracket 160 and a limiting plate 170. The bracket 160 is disposed on the pushing base 110 and located on both sides of the insulating member 150 along a first direction. The limiting plate 170 is disposed on the side of the insulating member 150 away from the pushing base 110 and is connected to the bracket 160. The bracket 160 is disposed on both sides of the pushing base 110 along the first direction and extends toward the stationary contact member 200. Furthermore, the limiting plate 170 is located above the mounting body 121 of the insulating member 150, and both ends of the limiting plate 170 are simultaneously connected to the bracket 160. The insulating member 150 can achieve insulation isolation between the bracket 160 and the limiting plate 170.

[0244] The bracket 160 and the limiting plate 170 can be configured to form an installation area, thereby limiting the central area of ​​the moving contact 120 and the compression spring within this area. In this way, the bracket 160 can limit the moving contact 120 on both sides along the first direction, preventing the moving contact 120 from wobbling in the width direction. Simultaneously, the limiting plate 170 can limit the upward movement of the moving contact 120 pushed by the compression spring 140, preventing the compression spring 140 from excessively pushing the moving contact 120 upward. Optionally, the bracket 160 is U-shaped, with its two sides located on both sides of the insulating member 150 along the first direction. Optionally, the bottom of the bracket 160 is integrally injection molded with the push seat 110.

[0245] See Figures 12 to 14 , Figures 16 to 18 In one embodiment, the bracket 160 and the push seat 110 are integrally injection molded, and the limiting plate 170 is snapped and / or riveted to the bracket 160. That is, the bracket 160 and the push seat 110 are integrally molded by injection molding. This allows the bracket 160 and the push seat 110 to move synchronously and improves the structural strength of the connection between the bracket 160 and the push seat 110, preventing breakage at the connection point.

[0246] Meanwhile, the limiting plate 170 and the bracket 160 are connected by snap-fit ​​and / or riveting, which facilitates the assembly of the compression spring 140 and the moving contact 120. This also ensures a reliable connection between the limiting plate 170 and the bracket 160, preventing loosening and ensuring reliable positioning of the moving contact 120. Optionally, the limiting plate 170 is fixed to the bracket 160 by snap-fit. Of course, in other embodiments, the limiting plate 170 can also be fixed to the bracket 160 by riveting or by a combination of snap-fit ​​and riveting.

[0247] See Figure 11 and Figure 21 In one embodiment, the main body 111 is configured to have a plurality of isolation ribs 11103 protruding from the surface opposite to the static contact member 200, the plurality of isolation ribs 11103 extending along a first direction and / or a second direction. Figure 11 for Figure 4 The bottom view of the push component 100 shown. Figure 21 for Figure 19 The image shows a bottom view of the push assembly 100. That is, the isolation ribs 11103 are provided on the lower surface of the main body 111, and multiple isolation ribs 11103 are crisscrossed on the main body 111.

[0248] In this way, the isolation rib 11103 can increase the structural strength of the main body seat 111, and at the same time, it can further increase the insulation path of the main body seat 111 and increase the creepage distance. Of course, in other embodiments, the surface of the main body seat 111 away from the stationary contact member 200 can also be provided with an isolation groove extending along the first direction and / or the second direction. The isolation groove can increase the creepage distance without affecting the structural strength of the push seat 110.

[0249] See Figures 1 to 3 , Figure 12 and Figure 13 This application also provides a relay 10, including a stationary contact 200, a frame 300, a magnetic housing 400, a magnetic circuit assembly 500, an insulating cover 600, and a push assembly 100 as described in any of the above embodiments. The push assembly 100 is partially disposed in the magnetic housing 400, and the push rod 130 of the push assembly 100 passes through the magnetic housing 400. The frame 300 covers the magnetic housing 400, and the insulating cover 600 is disposed on the side of the frame 300 away from the magnetic housing 400. The stationary contact 200 passes through the insulating cover 600 and is opposite to the moving contact 120 in the push assembly 100 along a third direction. The magnetic circuit assembly 500 is disposed on the side of the magnetic housing 400 away from the frame 300 and drives the push rod 130 to cause the moving contact 120 to contact or separate from the stationary contact 200 along a third direction.

[0250] The relay 10 of this application, by employing the push assembly 100 of the above embodiment, can limit the push base 110 relative to the magnetic housing 400, preventing the push base 110 from deflecting or tilting under long-term high-frequency operation of the relay 10 or external vibration interference. This ensures that the push base 110 always moves linearly along a preset trajectory, improving the vibration resistance, mechanical life, and contact operation reliability of the relay 10. Simultaneously, the relay 10's contact or separation with the stationary contact 200 through the moving contact 120 ensures the stability and reliability of the relay 10's operation.

[0251] See Figure 3 , Figure 4 , Figure 7 , Figure 9 , Figure 13 , Figure 17 and Figure 18In one embodiment, the actuating component 100 includes at least two moving contacts 120, and the relay 10 includes at least four stationary contacts 200. Each moving contact 120 has two ends corresponding to a stationary contact 200, forming a conductive path.

[0252] At least two moving contacts 120 are spaced apart along a first direction. After the two ends of the moving contacts 120 extend upward, each end of the moving contact 120 corresponds to a stationary contact 200. When the two ends of the moving contacts 120 simultaneously contact the stationary contacts 200, the two stationary contacts 200 are connected to an external circuit. At this time, the moving contacts 120, the two stationary contacts 200, and the external circuit can form a conductive path.

[0253] When the pusher 110 simultaneously pushes at least two moving contacts 120 upwards in a third direction, both ends of each moving contact 120 contact with the corresponding stationary contact 200. Thus, after at least two moving contacts 120 contact with their corresponding stationary contacts 200, at least two conductive paths are formed. It should be noted that each moving contact 120 abuts against its mating stationary contact 200; that is, each stationary contact 200 only contacts its corresponding moving contact 120 and not the other stationary contacts 200.

[0254] In this way, at least two moving contacts 120 can contact at least four stationary contacts 200, thereby forming at least two different conductive paths, each of which can carry current. Thus, the external circuit can simultaneously carry current through at least two conductive paths to meet the usage requirements of the relay 10 in different scenarios and improve the reliability of the relay 10's operation.

[0255] In this embodiment, the pushing component 100 includes two moving contacts 120, and correspondingly, the relay 10 includes four stationary contacts 200. Each moving contact 120 has one stationary contact 200 at each end. When the pushing seat 110 pushes the moving contact 120 into contact with the stationary contact 200, two different conductive paths can be formed. Of course, in other embodiments, the number of moving contacts 120 can be other, and the number of stationary contacts 200 can be adapted to the number of moving contacts 120.

[0256] See Figure 1 , Figure 2 and Figure 12 In one embodiment, the insulating cover 600 has two insulating cavities 610, which are independent of each other. Each insulating cavity 610 is provided with a static contact 200 corresponding to at least two conductive paths. The moving contact 120 contacts the corresponding static contact 200 in the insulating cavity 610 to make the corresponding conductive path open.

[0257] The two ends of the moving contact 120 are respectively located in two insulating cavities 610. The two insulating cavities 610 are spaced apart along the second direction, and are independent of each other and not connected. One end of each moving contact 120 is located in one of the insulating cavities 610 and is opposite to the corresponding stationary contact 200 in that insulating cavity 610. The other end of each moving contact 120 is located in the other insulating cavity 610 and is opposite to the corresponding stationary contact 200 in that insulating cavity 610.

[0258] That is, each insulating cavity 610 is provided with at least two stationary contacts 200, which are spaced apart along a first direction, and each stationary contact 200 corresponds to the end of a moving contact 120. When the push seat 110 pushes the moving contact 120 upward along a third direction, the ends of at least two moving contacts 120 can contact the corresponding stationary contacts 200 in the corresponding insulating cavity 610.

[0259] In this way, the two insulating cavities 610 can separate the process of the two ends of the moving contact 120 contacting the stationary contact 200, so that the process of the moving contact 120 contacting the stationary contact 200 is realized in two independent insulating cavities 610, ensuring insulation performance, avoiding mutual interference, improving the reliability of the contact between the moving contact 120 and the stationary contact 200, and thus improving the reliability of the relay 10 operation.

[0260] See Figure 1 , Figure 2 and Figure 12 In one embodiment, the relay 10 includes two independent insulating covers 600, each insulating cover 600 having an insulating cavity 610. That is, this embodiment uses two insulating covers 600, and the inner cavity of each insulating cover 600 is an independent insulating cavity 610. The two insulating covers 600 are disposed on the frame 300 and respectively cover the two ends of the moving contact 120, and the corresponding stationary contact 200 is disposed in the insulating cover 600.

[0261] Thus, the two insulating covers 600 are spaced apart along the second direction to form two independent insulating cavities 610. In this way, the two insulating covers 600 separate the contact process between the two ends of the moving contact 120 and the stationary contact 200, allowing the contact process between the moving contact 120 and the stationary contact 200 to occur within the two independent insulating cavities 610. This ensures insulation performance, avoids mutual interference, and improves the reliability of the contact between the moving contact 120 and the stationary contact 200, thereby improving the reliability of the relay 10's operation.

[0262] Of course, in other embodiments, the relay 10 includes an insulating cover 600, which has a partition that divides the inner cavity of the insulating cover 600 into two insulating cavities 610. That is, only one insulating cover 600 can be used, with a partition inside the insulating cover 600. The partition can also form two independent insulating cavities 610 inside the insulating cover 600, so that the contact process between the moving contact 120 and the stationary contact 200 is realized in the two independent insulating cavities 610, avoiding mutual interference, improving the reliability of the contact between the moving contact 120 and the stationary contact 200, and thus improving the reliability of the relay 10 operation.

[0263] See Figure 2 In one embodiment, the magnetic circuit assembly 500 includes a coil 520, a yoke frame 510, a movable magnetic conductor 540, and a coil frame 530. The coil frame 530 is disposed within the receiving space of the yoke frame 510. The coil 520 is disposed outside the coil frame 530. The movable magnetic conductor 540 is movably disposed within the coil frame 530 in a third direction. One end of the push rod 130, away from the push base 110, passes through the magnetic housing 400 and extends into the movable magnetic conductor 540, connecting with the movable magnetic conductor 540. The coil 520 is wound around the outside of the coil frame 530 and located within the yoke frame 510. That is, the coil 520 is located between the coil frame 530 and the yoke frame 510, and the coil 520 is wound with enameled wire.

[0264] Coil 520 can be electrically connected to an external power source. When the external power source energizes coil 520, coil 520 generates a magnetic field, which in turn forms a closed magnetic circuit with yoke frame 510. Yoke frame 510 guides and constrains the magnetic lines of force, ensuring that most of them run along the designed closed magnetic circuit, thereby minimizing the dissipation of the magnetic field and reducing magnetic leakage. When the external power source is de-energized, coil 520 no longer generates a magnetic field.

[0265] The movable magnetic conductor 540 is movably disposed within the coil holder 530. The push rod 130, after passing through the magnetic housing 400, can extend into the movable magnetic conductor 540 and move synchronously with it. When the coil 520 is energized, the magnetic housing 400 attracts the movable magnetic conductor 540, which in turn drives the push rod 130 to move upwards in a third direction. This causes the push seat 110 to push the movable contact 120 upwards and into contact with the stationary contact 200, thus achieving the on / off control of the relay 10. When the coil 520 is de-energized, the magnetic housing 400 releases its attraction to the movable magnetic conductor 540, which moves downwards and drives the push rod 130 downwards in a third direction. This causes the push seat 110 to drive the movable contact 120 downwards and separate it from the stationary contact 200, thus achieving the off / off control of the relay 10.

[0266] After the coil frame 530 is placed in the receiving space of the yoke frame 510, the magnetic housing 400 is placed on top of the yoke frame 510 and the coil frame 530. The magnetic housing 400 can abut against the top of the coil frame 530. The coil frame 530 supports and positions the magnetic housing 400, thereby achieving the positioning and constraint of the magnetic housing 400. This prevents the position of the magnetic housing 400 from shifting or tilting during subsequent assembly and fixing, and improves the reliability and consistency of the fixed connection between the magnetic housing 400 and the yoke frame 510.

[0267] See Figure 2 In one embodiment, the pushing assembly 100 further includes an elastic element 550, which is sleeved on the push rod 130 and located in the metal cup 570. The elastic element 550 can abut against the moving magnetic conductor 540 and the magnetic housing 400. Optionally, the elastic element 550 is a spring. The elastic element 550 can realize the reset of the moving magnetic conductor 540, thereby keeping the moving contact 120 separated from the stationary contact 200.

[0268] When the coil 520 is energized, the magnetic housing 400 attracts the moving magnetic body 540. The moving magnetic body 540 then compresses the elastic element 550 and drives the push rod 130 upwards along a third direction, causing the push seat 110 to push the moving contact 120 upwards and into contact with the stationary contact 200, thus achieving the conduction control of the relay 10. When the coil 520 is de-energized, the magnetic housing 400 releases its attraction to the moving magnetic body 540. Under the influence of gravity and the elastic force of the elastic element 550, the moving magnetic body 540 moves downwards, driving the push rod 130 downwards along a third direction, causing the push seat 110 to drive the moving contact 120 downwards and separate it from the stationary contact 200, thus achieving the disconnection control of the relay 10.

[0269] See Figure 2 In one embodiment, the relay 10 further includes a stationary magnet 560, which is fixed to the magnetic housing 400 and located within the metal cup 570. One end of the elastic member 550 abuts against the movable magnet 540, and the other end abuts against the stationary magnet 560. The stationary magnet 560 and the movable magnet 540 are spaced apart along a third direction. The stationary magnet 560 is capable of attracting the movable magnet 540 after the coil 520 is energized.

[0270] When coil 520 is energized, stationary magnet 560 attracts moving magnet 540, which in turn compresses elastic element 550 and drives push rod 130 upward in a third direction. This causes push base 110 to push moving contact 120 upward and into contact with stationary contact 200, thus enabling relay 10 to conduct. When coil 520 is de-energized, stationary magnet 560 releases its attraction to moving magnet 540. Under the influence of gravity and the elastic force of elastic element 550, moving magnet 540 downward, it drives push rod 130 downward in a third direction. This causes push base 110 to drive moving contact 120 downward and separate it from stationary contact 200, thus enabling relay 10 to disconnect.

[0271] See Figure 2 In one embodiment, the magnetic circuit assembly 500 further includes a metal cup 570, which is disposed in the coil frame 530 and connected to the magnetic housing 400. A movable magnetic conductor 540 is movably disposed in the metal cup 570 in a third direction. The metal cup 570 is fixed to the bottom of the magnetic housing 400 and located in the middle cavity of the coil frame 530, while the movable magnetic conductor 540 is movably disposed in the metal cup 570.

[0272] The metal cup 570 serves as a magnetic conductor, providing a low magnetic resistance path for the magnetic lines of force. It also closes the magnetic circuit with the magnetic sleeve, yoke frame 510, and magnetic housing 400, thereby increasing electromagnetic attraction and improving response speed and sensitivity. Simultaneously, the metal cup 570 supports and limits the moving magnetic conductor 540, allowing it to reciprocate along a third direction within the metal cup 570, thus protecting the moving magnetic conductor 540. Optionally, the metal cup 570 is made of a soft magnetic material with high permeability.
