The moving spring plate is provided with a moving contact, and at least two moving spring shaft holes are formed in the moving spring plate. The compression spring plate is in elastic contact with the moving spring plate, and at least two compression spring shaft holes are formed in the compression spring plate. The number of the shafts is at least two, and each of the shafts is arranged in one of the moving spring shaft holes of the moving spring plate and one of the compression spring shaft holes of the compression spring plate. The number of the shafts is at least two, and the compression spring plate and the moving spring plate are not assembled in relative positions by using only one shaft. Therefore, the two or more shafts between the moving spring plate and the compression spring plate can prevent the moving contact assembly from rotating around the axis provided by the shaft, and the two or more shafts can resist the circumferential rotation of the moving contact assembly, so that the precise alignment contact between the moving contact of the contact assembly and the static contact of the static contact assembly can be formed, and the stability of the contact is improved.

Description

Technical Field

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

[0002] Relays, as control components, are driving devices that use small current to control large current, and are widely used in aerospace, automotive, home appliances, industrial control, and other fields. With the rapid development of the Internet, Internet data centers are crucial for supporting Internet services. Magnetic latching relays are typically used in their power supply circuits for power switching control, ensuring that in the event of a main power failure, the relay can quickly switch to a backup power supply upon receiving a control signal, thus minimizing losses due to the failure.

[0003] During operation, a relay requires the moving contact of the moving contact component to make contact with or separate from the stationary contact of the stationary contact component. Therefore, the contact stability between the moving and stationary contacts determines the operational stability of the relay. However, in related technologies, the moving contact component is prone to deflection during rapid movement when switching, which affects the contact stability between the moving and stationary contacts and can easily lead to power supply failures. This is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to provide a moving contact component, a contact system, and a relay to address the aforementioned technical problems.

[0005] This application provides a dynamic contact assembly, the dynamic contact assembly comprising:

[0006] A movable spring, wherein the movable spring is provided with a movable contact and the movable spring has at least two movable spring shaft holes;

[0007] A compression spring sheet is elastically in contact with the movable spring sheet, and the compression spring sheet has at least two compression spring shaft holes;

[0008] The number of mandrels is configured to be at least two, each mandrel passing through a moving spring shaft hole of the moving spring and a compression spring shaft hole of the compression spring;

[0009] A receiving component is connected to a plurality of the said spindles, and the pressure spring is located between the moving spring and the receiving component, and the receiving component and the pressure spring elastically abut against each other.

[0010] In one embodiment, the receiving member has at least two receiving shaft holes, and each of the mandrels passes through one of the moving spring shaft holes of the moving spring, one of the compression spring shaft holes of the compression spring, and one of the receiving shaft holes of the receiving member; and / or,

[0011] The mandrel is fixedly connected to the receiving component; and / or

[0012] The mandrel is movably connected to the movable spring shaft hole; and / or,

[0013] The mandrel is movably connected to the compression spring shaft hole; and / or,

[0014] The movable spring has an X-axis direction and a Y-axis direction, and a plurality of movable spring shaft holes are distributed along the Y-axis direction on the movable spring; and / or

[0015] The compression spring includes a central compression spring portion and two outer compression spring portions located on both sides of the central compression spring portion. The compression spring shaft hole is located in the central compression spring portion. The receiving member elastically abuts against the central compression spring portion of the compression spring. The width of the outer compression spring portion gradually decreases along the direction away from the central compression spring portion, and the outer end of the outer compression spring portion is provided with a bent abutting portion, which elastically abuts against the moving spring.

[0016] In one embodiment, the mandrel includes a first shaft segment, a second shaft segment, and a limiting shaft end connected sequentially. The diameters of the first shaft segment and the second shaft segment are different. The first shaft segment movably passes through the compression spring shaft hole of the compression spring sheet and is fixedly connected to the receiving member. The second shaft segment movably passes through the movable spring shaft hole of the movable spring sheet. The limiting shaft end makes limiting contact with the movable spring sheet on the side of the movable spring sheet opposite to the compression spring sheet. The diameter of the first shaft segment is smaller than the diameter of the second shaft segment; and / or,

[0017] Several of the aforementioned moving spring shaft holes are linearly distributed along the Y-axis direction on the moving spring sheet; and / or,

[0018] The number of holes for the moving spring shaft is configured to be two; and / or,

[0019] A plurality of the aforementioned compression spring shaft holes are distributed relative to the moving spring along the Y-axis direction on the compression spring; and / or,

[0020] The number of compression spring shaft holes is configured to be two; and / or,

[0021] The movable spring is provided with two movable contacts, which are distributed along the X-axis direction on the movable spring.

[0022] This application provides a contact system, the contact system comprising:

[0023] A movable component having mounting holes, the movable component being configured for movably mounting to a base of a relay;

[0024] The moving contact assembly is mounted on the moving member via a locking member. The locking member includes a pressure cap and multiple elastic arms. The pressure cap is located outside the moving member and abuts against the moving member. The elastic arms pass through the mounting hole and can hold the moving member tightly by their own rebound force to lock it, thereby enabling the pressure cap to press the moving contact assembly onto the moving member.

[0025] In one embodiment, the number of elastic arms and the number of mounting holes are both set to two and correspond one-to-one with each other. The two elastic arms are tilted in a direction that is close to or far from each other so that the two elastic arms can rebound in a direction that is close to or far from each other, and the rebound direction of the elastic arms is parallel or perpendicular to the length direction of the moving member.

[0026] In one embodiment, the end of the elastic arm away from the pressure cap is provided with a claw, the claw extending along the rebound direction of the elastic arm and abutting against the outer wall of the moving member; and / or,

[0027] The pressure cap has a first limiting part on the side facing the movable member, and the movable member has a second limiting part on the side facing the pressure cap. The first limiting part and the second limiting part cooperate to limit the pressure cap in a direction perpendicular to the springback direction of the elastic arm. One of the first limiting part and the second limiting part is a groove, and the other is a protrusion inserted into the groove.

[0028] In one embodiment, the elastic arm is aligned with the first limiting portion in its own rebound direction, or the elastic arm extends from the second limiting portion in a direction away from the pressure cap.

[0029] In one embodiment, there are multiple moving contact components, which are spaced apart along the length of the moving member; at least one locking member is provided, each locking member being disposed between two adjacent moving contact components and pressing the two adjacent moving contact components onto the moving member; and / or

[0030] The movable component has a insertion cavity, which includes a through hole and a groove. The through hole is used for the movable spring to pass through, and the pressure cap can press the receiving component into the groove through the slot of the groove.

[0031] In one embodiment, the free end of the first shaft segment extends out of the receiving member; the groove wall of the groove portion facing the through hole portion has at least two receiving grooves for receiving the corresponding free end of the first shaft segment;

[0032] The insertion cavity is provided with a stop portion, which is located at the junction between the through hole portion and the groove portion and abuts against the receiving member.

[0033] This application provides a relay, the relay comprising:

[0034] The base has a contact cavity and a magnetic circuit cavity inside, and the contact cavity and the magnetic circuit cavity are connected by a linkage channel;

[0035] The contact system is assembled into the contact cavity;

[0036] A magnetic circuit system is assembled in the magnetic circuit cavity, and the magnetic circuit system is drivenly connected to the contact system in the contact cavity via the linkage channel.

[0037] Assuming the pressure spring and the moving spring are assembled relative to each other using a mandrel, the pressure spring and the moving spring can share a fixed axis of rotation based on this mandrel, allowing them to rotate around this axis. However, this fixed-axis rotation between the pressure spring and the moving spring can easily cause a circumferential offset in the moving contact assembly, affecting the precise alignment and contact between the moving contact of the moving contact assembly and the stationary contact of the stationary contact assembly.

[0038] In the aforementioned moving contact assembly, contact system, and relay, there are at least two spindles; the pressure spring and moving spring are not assembled relative to each other using only one spindle. Therefore, the two or more spindles between the moving spring and the pressure spring prevent the moving contact assembly from rotating on a fixed axis provided by a single spindle. Instead, the two or more spindles resist the circumferential rotation of the moving contact assembly, thereby ensuring precise alignment between the moving contact of the contact assembly and the stationary contact of the stationary contact assembly, and improving contact stability.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] See Figures 1 to 19As shown, this application provides a relay, which may include a base, a contact system, and a magnetic circuit system. The base serves as the assembly foundation for the contact system and the magnetic circuit system, and can be designed with a structure that facilitates the assembly of the contact system and the magnetic circuit system. For example, the base has a contact cavity and a magnetic circuit cavity inside, which are connected by a linkage channel. The contact system is assembled in the contact cavity, and the magnetic circuit system is assembled in the magnetic circuit cavity. The magnetic circuit system is drivenly connected to the contact system in the contact cavity via the linkage channel. Those skilled in the art can design the base structure of the relay according to actual needs, and no limitation is made here.

[0077] See Figures 1 to 10 As shown, this application provides a moving contact assembly 100, which may include components such as a moving spring 1000, a pressure spring 2000, and a spindle 3000. The moving spring 1000 is provided with a moving contact 1100, and the moving spring 1000 has at least two moving spring shaft holes 1001. The pressure spring 2000 is in elastic contact with the moving spring 1000, and the pressure spring 2000 has at least two pressure spring shaft holes 2001. The elastic contact between the pressure spring 2000 and the moving spring 1000 can be achieved by assembling them together using the spindle 3000.

[0078] like Figure 3 and Figure 4 As shown, the number of mandrels 3000 is configured to be at least two. For example, the number of mandrels 3000 can be two, three, or other numbers. The number of moving spring shaft holes 1001 and compression spring shaft holes 2001 needs to match the design number of mandrels 3000, so that each mandrel 3000 can pass through one moving spring shaft hole 1001 of the moving spring 1000 and one compression spring shaft hole 2001 of the compression spring 2000, so that the compression spring 2000 and the moving spring 1000 can be assembled relative to each other. At this time, the compression spring 2000 and the moving spring 1000 can be assembled relative to each other simultaneously through two or more mandrels 3000, instead of using only one mandrel 3000 to assemble the compression spring 2000 and the moving spring 1000 relative to each other.

[0079] Assuming that the pressure spring 2000 and the moving spring 1000 are assembled relative to each other using a spindle 3000, the pressure spring 2000 and the moving spring 1000 can have a fixed axis of rotation based on the spindle 3000, allowing them to rotate around a fixed axis. However, this fixed-axis rotation between the pressure spring 2000 and the moving spring 1000 can easily cause a circumferential displacement of the moving contact assembly 100, affecting the precise alignment and contact between the moving contact 1100 of the moving contact assembly 100 and the stationary contact of the stationary contact assembly 200.

[0080] Therefore, in the design scheme provided in this application, there are at least two spindles 3000, and the compression spring 2000 and the moving spring 1000 are not assembled relative to each other using only one spindle 3000. Thus, the two or more spindles 3000 between the moving spring 1000 and the compression spring 2000 prevent the moving contact assembly 100 from rotating on a fixed axis based on the fixed axis of rotation provided by one spindle 3000. Instead, the two or more spindles 3000 resist the circumferential rotation of the moving contact assembly 100, thereby ensuring that the moving contact 1100 of the contact assembly and the stationary contact of the stationary contact assembly 200 can form a precise alignment contact, improving the stability of the contact.

[0081] Continue reading Figure 3 and Figure 4 As shown, in one embodiment, the moving contact assembly 100 may further include a receiving member 4000, which is connected to a plurality of spindles 3000. A compression spring 2000 is located between the moving spring 1000 and the receiving member 4000, and the receiving member 4000 and the compression spring 2000 elastically abut against each other. The receiving member 4000 may be configured as a plate-like structure, a block-like structure, or a regular or irregular structure. Those skilled in the art can design it according to actual needs, and no limitation is made here. In one embodiment, the receiving member 4000 has at least two receiving shaft holes 4001. In this case, each spindle 3000 passes through one moving spring shaft hole 1001 of the moving spring 1000, one compression spring shaft hole 2001 of the compression spring 2000, and one receiving shaft hole 4001 of the receiving member 4000.

[0082] At this time, the spindle 3000 and the receiving member 4000 can be fixedly connected, for example, the spindle 3000 can be fixedly inserted through the receiving shaft hole 4001 of the receiving member 4000. The spindle 3000 is movably connected to the movable spring shaft hole 1001 and also movably connected to the compression spring shaft hole 2001. In this state, the receiving member 4000 can be relatively fixed to the spindle 3000, and both the movable spring 1000 and the compression spring 2000 can slide relative to the spindle 3000 in the axial direction.

[0083] Therefore, when the moving contact assembly 100 provided in this application moves closer to or further away from the stationary contact assembly 200, and when the moving contact assembly 100 contacts or separates from the stationary contact assembly 200, both the moving spring 1000 and the compression spring 2000 can slide relative to the spindle 3000 in the axial direction of the spindle 3000 after being subjected to force, thereby forming a buffer and adaptive adjustment, improving motion stability and safety.

[0084] Continue reading Figures 3 to 6As shown, in one embodiment, the movable spring 1000 has an X-axis direction and a Y-axis direction, and a plurality of movable spring shaft holes 1001 are distributed along the Y-axis direction in the movable spring 1000. In this case, the plurality of movable spring shaft holes 1001 arranged in the Y-axis direction allow the spindle 3000 to be assembled with the movable spring 1000 along the Y-axis direction, and the plurality of spindles 3000 arranged in the Y-axis direction allow the movable spring 1000 to be offset in the X-axis direction. For example, in one embodiment, the plurality of movable spring shaft holes 1001 are linearly distributed along the Y-axis direction in the movable spring 1000.

[0085] Accordingly, the number of movable spring shaft holes 1001 is configured to be two, and a number of compression spring shaft holes 2001 are distributed along the Y-axis direction relative to the movable spring 1000 on the compression spring 2000, with the number of compression spring shaft holes 2001 also configured to be two. When the movable spring 1000 is provided with two movable contacts 1100, and the two movable contacts 1100 are distributed along the X-axis direction on the movable spring 1000, the two movable contacts 1100 need to contact the two stationary contacts of the stationary contact assembly 200.

[0086] At this time, if the assembly gap between one pair of moving contacts 1100 and the stationary contact is inconsistent with the assembly gap between the other pair of moving contacts 1100 and the stationary contact, the moving spring 1000, which is capable of offsetting in the X-axis direction, can adaptively offset in the X-axis direction based on the relative force formed by the contact after the moving contacts 1100 and the stationary contact come into contact. This ensures that the assembly gap between one pair of moving contacts 1100 and the stationary contact can be adaptively adjusted to be consistent with the assembly gap between the other pair of moving contacts 1100 and the stationary contact, ensuring that the two pairs of moving contacts 1100 and the stationary contact contact as simultaneously as possible.

[0087] See Figure 7 and Figure 8 As shown, in one embodiment, the compression spring 2000 may include a compression spring center portion 2100 and two compression spring extension portions 2200 located on both sides of the compression spring center portion 2100, with the compression spring shaft hole 2001 located in the compression spring center portion 2100. The receiving member 4000 elastically abuts against the compression spring center portion 2100 of the compression spring 2000. The compression spring center portion 2100 may be designed as a quadrilateral region, and the compression spring extension portions 2200 may be configured as elongated plate structures, with the width of the compression spring extension portions 2200 gradually decreasing in the direction away from the compression spring center portion 2100. Simultaneously, a bent abutment portion 2300 is provided at the outer end of the compression spring extension portion 2200, which elastically abuts against the movable spring 1000.

[0088] See Figure 9 and Figure 10As shown, in one embodiment, the mandrel 3000 includes a first shaft segment 3100, a second shaft segment 3200, and a limiting shaft end 3300 connected in sequence. The diameters of the first shaft segment 3100 and the second shaft segment 3200 are different. Therefore, the diameters of the first shaft segment 3100 and the second shaft segment 3200 can be designed to match based on the dimensions of the compression spring shaft hole 2001 and the moving spring shaft hole 1001, for example, with an appropriate clearance fit. In one embodiment, the diameter of the first shaft segment 3100 is smaller than the diameter of the second shaft segment 3200.

[0089] At this time, the first shaft segment 3100 is movably inserted through the spring shaft hole 2001 of the spring plate 2000, and the first shaft segment 3100 is fixedly connected to the receiving member 4000. The second shaft segment 3200 is movably inserted through the spring shaft hole 1001 of the movable spring plate 1000. The limiting shaft end 3300 has a larger structural size, so that the limiting shaft end 3300 can make limiting contact with the movable spring plate 1000 on the side of the movable spring plate 1000 away from the spring plate 2000, preventing the movable spring plate 1000 and the spring plate 2000 from detaching from the spindle 3000, and ensuring the assembly stability of the component.

[0090] Continue reading Figures 1 to 19 As shown, the aforementioned contact system may include a movable element 10, a moving contact assembly 100, and a stationary contact assembly 200. The movable element 10 may be configured to be movably mounted on a base of a relay. The moving contact assembly 100 is mounted on the movable element 10 and can move on the base along with the movable element 10. The stationary contact assembly 200 can be mounted in the base. The moving contact assembly 100, reciprocating with the movable element 10, can move relative to the stationary contact assembly 200, causing the moving contact 1100 of the moving contact assembly 100 to contact or separate from the stationary contact of the stationary contact assembly 200. Those skilled in the art can design the structure of the contact system according to actual needs, and no limitations are imposed here.

[0091] The movable member 10 has a mounting hole 11. The moving contact assembly 100 is mounted on the movable member 10 via a locking member 30. The locking member 30 includes a pressure cover 31 and a plurality of elastic arms 32. The pressure cover 31 is located outside the movable member 10 and abuts against the movable member 10. The elastic arms 32 pass through the mounting hole 11 and can hold the movable member 10 tightly by their own rebound force to lock it, so that the pressure cover 31 can press the moving contact assembly 100 onto the movable member 10.

[0092] The relay 10 can be an electromagnetic relay, a motor relay, a magnetic latching relay, etc. For example, the relay 10 can be a magnetic latching relay. The movable member 10 is movably disposed in the contact cavity. The moving contact assembly 100 is installed on the movable member 10 by pressing with the locking member 30. The elastic arm 32 of the locking member 30 has a certain elasticity, so that after being squeezed and deformed, the elastic arm 32 can be smoothly inserted into the mounting hole 11 of the movable member 10, and finally rely on its own rebound force to hold the movable member 10 and lock it. Thus, the cover 31 can press the moving contact assembly 100 onto the movable member 10. This does not require applying a large installation force to the moving contact assembly 100 to achieve an interference fit with the movable member 10. It can effectively avoid the moving contact assembly 100 from contaminating the static and moving contacts due to the generation of plastic shavings during the assembly process, improve the reliability of the static and moving contact, and effectively fasten and limit the moving contact assembly 100.

[0093] Two elastic arms 32 are provided, and the two elastic arms 32 are tilted towards each other so that the two elastic arms 32 can rebound in the same direction. The tilting of the elastic arms 32 facilitates the rebound of the elastic arms 32 and can effectively hold the moving part 10. Regarding the tilt angle of the elastic arms 32, that is, the angle between the elastic arms 32 and the central axis of the locking part 30, this embodiment does not impose specific restrictions, as long as the elastic arms 32 can be smoothly inserted into the mounting hole 11 of the moving part 10 without failing to rebound due to excessive deformation, and also have sufficient rebound force to clamp the moving part 10, for example, it can be set to 10°, 15°, 20°, etc.

[0094] To enable the two elastic arms 32 to spring back and grip the moving member 10 in a direction close to each other, two mounting holes 11 are provided, each corresponding to one of the elastic arms 32. The distance between the two mounting holes 11 is less than the minimum distance between the two elastic arms 32 in their natural state. It should be noted that the natural state of the elastic arms 32 refers to the state in which the elastic arms 32 are not under force.

[0095] The diameter of the mounting hole 11 can be slightly larger than the thickness of the corresponding elastic arm 32. This design allows the elastic arm 32 to pass smoothly through the mounting hole 11, preventing excessive compression of the inner wall of the mounting hole 11 during the insertion process, thereby further reducing the likelihood of plastic debris generation. A claw 330 is provided at the end of the elastic arm 32 furthest from the pressure cap 31. The claw 330 extends along the springback direction of the elastic arm 32 and abuts against the outer wall of the moving member 10. The claw 330, through its cooperation with the pressure cap 31, can limit the elastic arm 32 in the insertion direction, preventing it from wobbling or even falling out of the mounting hole 11 of the moving member 10. The claws 330 of the two elastic arms 32 extend towards each other.

[0096] In this embodiment, a first limiting part 311 is provided on the side of the pressure cap 31 facing the movable member 10, and a second limiting part 12 is provided on the side of the movable member 10 facing the pressure cap 31. The first limiting part 311 and the second limiting part 12 cooperate to limit the pressure cap 31 in a direction perpendicular to the springback direction of the elastic arm 32. Through the cooperation of the first limiting part 311 and the second limiting part 12, the elastic arm 32 can be limited in a direction perpendicular to the insertion direction and the springback direction of the elastic arm 32, preventing the elastic arm 32 from shaking, thereby enabling the moving contact assembly 100 to be firmly installed on the movable member 10.

[0097] As an example, the second limiting portion 12 is a groove, and the first limiting portion 311 is a protrusion inserted into the groove. The elastic arm 32 extends from the second limiting portion 12 in a direction away from the pressure cap 31. This arrangement allows the elastic arm 32 to connect to the second limiting portion 12 without connecting to the pressure cap 31, giving the pressure cap 31 a larger area to press the actuating contact assembly 100, and also reducing the size of the pressure cap 31, making its structure more compact. The second limiting portion 12 can extend from one end of the pressure cap 31 to the other end along the rebound direction of the elastic arm 32.

[0098] As another example, the first limiting part 311 is a groove, and the second limiting part 12 is a protrusion inserted into the groove. In this example, the elastic arm 32 is aligned with the first limiting part 311 in the rebound direction. This arrangement does not affect the cooperation between the first limiting part 311 and the second limiting part 12, and also allows the pressure cap 31 to have a larger area in the direction perpendicular to the insertion direction and the rebound direction of the elastic arm 32 to press the actuating contact assembly 100.

[0099] In this embodiment, multiple moving contact components 100 are provided, and the multiple moving contact components 100 are spaced apart along the length direction of the moving member 10. Providing multiple moving contact components 100 increases the current-carrying area, making the relay 10 suitable for high-current electrical appliances, such as high-computing-power AI servers. Optionally, each of the two ends of the moving contact component 100 along the width direction of the moving member 10 is provided with a moving contact 211.

[0100] See also Figures 1 to 3At least one locking element 30 is provided, and each locking element 30 is located between two adjacent moving contact components 100, pressing the two adjacent moving contact components 100 onto the moving component 10. During installation, the two adjacent moving contact components 100 are first inserted into the moving component 10, and then the locking element 30 is inserted into the corresponding mounting hole 11 on the moving component 10. This achieves locking of the two adjacent moving contact components 100, which simplifies the disassembly and assembly steps of the moving contact components 100 and reduces the number of locking elements 30. In addition, this arrangement of locking elements 30 and moving contact components 100, i.e., one locking element 30 corresponds to two moving contact components 100, facilitates switching and can also meet the requirements for large gaps.

[0101] In this embodiment, the length direction of the movable member 10 is perpendicular to the rebound direction of the elastic arm 32, that is, the two elastic arms 32 are arranged at intervals along the width direction of the movable member 10. This arrangement not only allows the two elastic arms 32 to be spaced apart at the middle of the pressure cover 31 along the width direction of the movable member 10, so that the two ends of the pressure cover 31 along the length direction of the movable member 10 have sufficient area to press the moving contact assembly 100, but also allows the elastic arms 32 to have a large rebound space, which can effectively hold the movable member 10.

[0102] The movable member 10 has a insertion cavity 130, which includes a through hole 131 and a groove 132. The through hole 131 is used for the movable spring 1000 to pass through, and the pressure cap 31 is used to press the receiving member 4000 into the groove 132 through the groove opening. During installation, the movable spring 1000 and the receiving member 4000 of the movable contact assembly 100 can be inserted into the through hole 131 and the groove 132 respectively on the groove opening side of the groove 132. After the pressure cap 31 abuts against the bottom of the groove 132, the pressure cap 31 is then fastened onto the movable member 10, thereby pressing the movable contact assembly 100 onto the movable member 10.

[0103] The groove wall of the recess 132 facing the through hole 131 has at least two receiving grooves 14, which are used to receive the free end of the corresponding first shaft segment 3100, that is, the end of the first shaft segment 3100 away from the limiting shaft end 3300. The recess 132 can avoid the free end of the first shaft segment 3100, so that the receiving member 4000 can abut against the groove wall of the recess 132, which can prevent the moving contact assembly 100 from shaking in the length direction of the moving member 10 and ensure the secure installation of the moving contact assembly 100 on the moving member 10.

[0104] The insertion cavity 130 is provided with a stop portion 133, which is located at the junction between the through hole portion 131 and the groove portion 131 and abuts against the receiving member 4000. The stop portion 133 can limit the receiving member 4000 of the moving contact assembly 100 to be located in the groove portion 132, preventing the moving contact assembly 100 from shaking in the length direction of the moving member 10.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
