Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to a compression spring, a mating structure, and an electromagnetic relay. Background Technology

[0002] An electromagnetic relay is an electronic control device. It uses a push card to connect the moving spring in the contact part and the armature in the magnetic circuit part. When the armature moves, it drives the moving spring through the push card, so that the moving contact on the moving spring comes into contact with or separates from the stationary contact on the stationary spring.

[0003] In current electromagnetic relays, the compression spring is located on one surface of the moving spring. When the pusher pushes the compression spring to move the moving spring, the contact force between the moving contact on the moving spring and the stationary contact on the stationary spring is small. At the same time, there is a repulsive force when the moving contact and the stationary contact just make contact, which affects the reliable contact between the moving contact and the stationary contact. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the contact force between the moving contact and the stationary contact is small and there is a repulsive force in the current electromagnetic relays, so as to provide a spring, a matching structure and an electromagnetic relay that can increase the contact force between the moving contact and the stationary contact and resist the repulsive force, so as to make reliable contact between the moving contact and the stationary contact.

[0007] The damping elastic segment has a first part and a second part opposite to each other. The first part is connected to the first end, and the second part extends toward the direction of the moving spring lead-out plate and also extends away from the second end.

[0008] In one embodiment of this application, the main pressure elastic segment includes a first connecting segment, a bending segment, and a main pressure segment, wherein the first connecting segment is engaged with the movable spring.

[0009] The bending section bends to connect the first connecting section and the main pressure section, and the main pressure section extends in a direction away from the moving spring.

[0010] In one embodiment of this application, the first connecting segment is connected to the movable spring sheet, and the second part of the shock-absorbing elastic segment can abut against or disengage from the movable spring lead sheet.

[0011] In one embodiment of this application, the main pressure elastic segment further includes an installation segment, the installation segment is disposed on the first connecting segment, the movable spring has an installation hole, and the installation segment is inserted into the installation hole;

[0012] Alternatively, the compression spring may further include a first fastener, which is mounted on the movable spring through the first connecting section to fix the main compression elastic section to the movable spring.

[0013] In one embodiment of this application, the damping elastic segment includes a second connecting segment and a transition segment. The second connecting segment connects to the first end of the main pressure elastic segment and extends toward the direction of the moving spring lead-out sheet.

[0014] The transition section transitionally connects to the end of the second connecting section away from the first connecting section, and the transition section can engage the moving spring lead-out piece.

[0015] In one embodiment of this application, the first connecting segment abuts against the movable spring sheet, and the compression spring further includes a fixing component, which mounts the second part of the shock-absorbing elastic segment to the movable spring lead-out sheet.

[0016] In one embodiment of this application, the fixing component further includes a rotating member and a support base. The support base is disposed on the moving spring lead-out plate, and the rotating member is disposed on the second part of the shock-absorbing elastic section and is rotatably mounted on the support base.

[0017] Alternatively, the compression spring may further include a second fastener, which is mounted on the spring lead-out sheet through a second portion of the damping elastic section.

[0018] In one embodiment of this application, the main pressure elastic segment and the damping elastic segment are an integral structure;

[0019] And / or, the main pressure elastic segment has four first ends, the number of the damping elastic segments is two, two of the damping elastic segments are connected to two of the first ends, and the other two first ends are engaged with the moving spring.

[0020] A mating structure includes a movable spring portion and a pusher, wherein the movable spring portion includes a movable spring lead-out piece, a movable spring sheet, a contact point disposed on the movable spring sheet, and a compression spring as described in any of the above technical features;

[0021] One end of the movable spring is disposed on the movable spring lead-out piece, and the other end is installed in the push card. The compression spring is disposed between the movable spring lead-out piece and the movable spring.

[0022] An electromagnetic relay includes an electromagnetic drive structure, a stationary spring portion, and a mating structure as described in the above technical features;

After the main compression elastic segment is subjected to force, it can transmit the first force to the movable spring plate through the first end. At the same time, the movable spring lead plate applies a second force to the second part of the damping elastic segment, which is transmitted to the movable spring plate through the first end, so that the movable spring plate drives the movable contact to abut against the stationary contact on the stationary spring plate.

[0026] In this way, when the compression spring pushes the moving spring to make the moving contact contact with the stationary contact of the stationary spring, in addition to the first force on the main compression elastic section, the moving spring lead-out plate also applies a second force to the moving spring through the damping elastic section. This causes the moving contact to contact the stationary contact under the first and second forces, increasing the contact force between the moving and stationary contacts, enabling the moving and stationary contacts to make contact quickly, and resisting the repulsive force between the moving and stationary contacts. This ensures reliable contact between the moving and stationary contacts and achieves rapid compression of the moving spring. Attached Figure Description

Detailed Implementation

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Understandably, an electromagnetic relay is an electronic control device. It utilizes a push-lock mechanism connected between a moving spring in the contact section and an armature in the magnetic circuit. When the armature actuates, it drives the moving spring via the push-lock, causing the moving contact on the moving spring to contact or separate from the stationary contact on the stationary spring. However, when the push-lock pushes the pressure spring, causing the moving spring to move, the contact force between the moving contact and the stationary contact is small. Furthermore, there is a repulsive force when the moving and stationary contacts first make contact, affecting reliable contact between them.

[0048] For this purpose, please refer to Figures 1 to 4 This application provides a novel compression spring 110. The compression spring 110 is used in the mating structure 10 of the electromagnetic relay 1. Figure 1 This is a schematic diagram of an electromagnetic relay 1 according to an embodiment of this application. Figure 2 for Figure 1 The exploded view of electromagnetic relay 1 shown is shown below. Figure 3 for Figure 2 The diagram shown is a schematic of the electromagnetic relay 1 without its outer casing 50. Figure 4 for Figure 3 The front view of the static spring part 40, the mating structure 10, and the electromagnetic drive structure 30 shown.

[0049] To better illustrate the structure of the compression spring 110, the structure of the electromagnetic relay 1 and its cooperating structure 10 will be briefly introduced here. (See also...) Figures 1 to 4In one embodiment, the mating structure 10 includes a movable spring portion 100 and a pusher 200. The movable spring portion 100 includes a movable spring sheet 120, a movable contact 140 disposed on the movable spring sheet 120, a movable spring lead-out sheet 130, and a compression spring 110 of this application. The top of the movable spring sheet 120 is connected to the movable spring lead-out sheet 130, and the compression spring 110 is disposed between the movable spring lead-out sheet 130 and the movable spring sheet 120, so that the bottom of the movable spring sheet 120 is away from the movable spring lead-out sheet 130.

[0050] The electromagnetic relay 1 includes an electromagnetic drive structure 30, a stationary spring portion 40, and the aforementioned mating structure 10. The electromagnetic drive structure 30 and the stationary spring portion 40 are disposed opposite to each other, and the mating structure 10 is movably disposed between the electromagnetic drive structure 30 and the stationary spring portion 40. The electromagnetic drive structure 30 can drive the push card 200 to move, causing the push card 200 to drive the moving spring portion 100 to move, thereby causing the moving spring portion 100 to contact or separate from the stationary spring portion 40, realizing the closing or opening of the electromagnetic relay 1.

[0051] Specifically, the stationary spring portion 40 includes a stationary spring plate 410 and a stationary contact 420 disposed on the stationary spring plate 410. When the electromagnetic drive structure 30 drives the push card 200 to move toward the stationary spring plate 410, the push card 200 can push the compression spring 110, and the compression spring 110 can apply a force to the moving spring plate 120, causing the moving spring plate 120 to move toward the stationary spring plate 410, thereby causing the moving contact 140 on the moving spring plate 120 to contact the stationary contact 420 on the stationary spring plate 410, and the electromagnetic relay 1 closes to conduct the circuit.

[0052] When the electromagnetic drive structure 30 drives the push card 200 to move away from the stationary spring 410, the push card 200 can contact the moving spring 120 and drive the moving spring 120 to move away from the stationary spring 410, so that the moving contact 140 on the moving spring 120 is separated from the stationary contact 420 on the stationary spring 410, and the electromagnetic relay 1 is disconnected to disconnect the circuit.

[0053] See Figure 1 and Figure 2 In one embodiment, the electromagnetic relay 1 further includes a housing 50, within which the electromagnetic drive structure 30, the mating structure 10, and the stationary spring portion 40 are disposed. The housing 50 provides protection for the electromagnetic drive structure 30, the mating structure 10, and the stationary spring portion 40. Figure 3 and Figure 4 In the middle, the outer shell 50 of the electromagnetic relay 1 is removed to expose the stationary spring part 40, the moving spring part 100, the push card 200 and the electromagnetic drive structure 30 in the electromagnetic relay 1.

[0054] It is worth noting that the focus of this application is on the structure of the compression spring 110 and the cooperation between the compression spring 110, the moving spring 120, and the moving spring lead-out piece 130. The structure and principle of the electromagnetic drive structure 30, the stationary spring part 40, and the push card 200 are not the focus of this application. The structure and connection relationship of the electromagnetic drive structure 30, the stationary spring part 40, and the push card 200 can adopt existing structures, and will not be described in detail here. Furthermore, the following description uses the compression spring 110 to push the moving spring 120 to make the moving contact 140 contact with the stationary contact 420 on the stationary spring 410. The separation of the moving contact 140 and the stationary contact 420 will not be described in detail.

[0055] The compression spring 110 of this application is engaged between the movable spring plate 120 and the movable spring lead plate 130. When the pusher 200 applies a first force F1 (pushing force) to the compression spring 110, the compression spring 110 can apply the first force F1 to the movable spring plate 120. At the same time, the movable spring lead plate 130 can also apply a second force F2 to the compression spring 110 and apply the second force F2 to the movable spring plate 120. In this way, through one push operation of the pusher 200, the pusher 200 and the movable spring lead plate 130 can apply the resultant force F of the first force F1 and the second force F2 to the compression spring 110, which greatly increases the contact force between the movable contact 140 on the movable spring plate 120 and the stationary contact 420 on the stationary spring plate 410.

[0056] When the compression spring 110 of this application pushes the movable spring 120 to make the movable contact 140 contact with the stationary contact 420 of the stationary spring 410, it can increase the force on the movable spring 120, so that the movable contact 140 and the stationary contact 420 can make contact quickly, thereby increasing the contact force between the movable contact 140 and the stationary contact 420 and resisting the repulsive force between the movable contact 140 and the stationary contact 420, so that the movable contact 140 and the stationary contact 420 can make reliable contact, and realize the rapid pressing of the movable spring 120.

[0057] See Figures 3 to 9 In one embodiment, the compression spring 110 includes a main compression elastic segment 111 and a damping elastic segment 112. The main compression elastic segment 111 has opposing first ends 1111 and second ends 1112, with the first end 1111 engaging the movable spring sheet 120 and the second end 1112 extending in a direction away from the movable spring sheet 120. The damping elastic segment 112 has opposing first portions 1121 and second portions 1122, with the first portion 1121 connected to the first end 1111 and the second portion 1122 extending in a direction toward the movable spring lead-out sheet 130 and also in a direction away from the second end 1112. Figure 5 for Figure 4 The schematic diagram of the mating structure 10 shown is as follows. Figure 6 for Figure 5 A schematic diagram of the movable spring portion 100 in the shown mating structure 10. Figure 7 for Figure 6 A schematic diagram of the compression spring 110 in the first embodiment of the movable spring portion 100 shown. Figure 8 for Figure 7 The side view of the compression spring 110 shown is shown. Figure 9 for Figure 6 The shown front view of the moving spring portion 100 is based on the first embodiment where the compression spring 110 and the stationary spring portion 40 are engaged.

[0058] The main compression elastic section 111 is the force-bearing component of the compression spring 110, and the damping elastic section 112 is the damping component of the compression spring 110. The main compression elastic section 111 and the damping elastic section 112 extend along the height direction (vertical direction), and the compression spring 110 is connected between the moving spring 120 and the stationary spring 410 along the thickness direction (horizontal direction). Regarding the height direction, thickness direction, and width direction (front-back direction) as follows... Figures 4 to 6 As shown, when describing the structure of the compression spring 110 later, only the following description will be used. Figures 4 to 6 The direction shown is the reference. Furthermore, Figures 4 to 7 When in use, the compression spring 110 shown is arranged vertically, and the pusher 200 is arranged horizontally. The pusher 200 moves horizontally to drive the moving spring portion 100 to move toward or away from the stationary spring portion 40.

[0059] See Figure 7 and Figure 8 The main pressure elastic segment 111 has a first end 1111 and a second end 1112 facing each other. The first end 1111 of the main pressure elastic segment 111 is located above, and the second end 1112 of the main pressure elastic segment 111 is located below. The main pressure elastic segment 111 is engaged with the movable spring 120 through the first end 1111. The second end 1112 of the main pressure elastic segment 111 extends downward and also extends in a direction away from the movable spring 120. In this application, the engagement includes, but is not limited to, connection, and may also be abutment, etc. The specific limitations of the engagement will be mentioned later.

[0060] In other words, the main pressure elastic segment 111 slopes from the upper left to the lower right. Thus, the compression spring 110 engages with the movable spring 120 through the first end 1111 of the main pressure elastic segment 111, and cooperates with the pusher 200 through the second end 1112 of the main pressure elastic segment 111. The pusher 200 pushes the second end 1112 of the main pressure elastic segment 111, thereby pushing the compression spring 110 to move the movable spring 120 toward the stationary spring 410, so that the movable contact 140 on the movable spring 120 contacts the stationary contact 420 on the stationary spring 410.

[0061] See Figure 7 and Figure 8The damping elastic segment 112 has a first part 1121 and a second part 1122, with the first part 1121 located below and the second part 1122 located above. The damping elastic segment 112 is connected to the first end 1111 of the main compression elastic segment 111 via the first part 1121. The second part 1122 extends upward and also extends toward the moving spring lead-out piece 130 to engage with it. In other words, the damping elastic segment 112 is inclined from the lower left to the upper right. Thus, the compression spring 110 engages with the main compression elastic segment 111 via the first part 1121 of the damping elastic segment 112 and with the moving spring lead-out piece 130 via the second part 1122 of the damping elastic segment 112.

[0062] In this application, the first end 1111 of the main compression elastic segment 111 is connected to the first part 1121 of the damping elastic segment 112, and the second end 1112 of the main compression elastic segment 111 and the second part 1122 of the damping elastic segment 112 extend in opposite directions and simultaneously extend away from the moving spring 120. Thus, the main compression elastic segment 111 and the damping elastic segment 112 arch at the connection point, that is, the compression spring 110 has an arched structure that is high in the middle and low at both ends.

[0063] In this way, the compression spring 110 engages with the movable spring 120 through the first end 1111 of the main compression elastic section 111 and the movable spring 120 through the second part 1122 of the damping elastic section 112. When the pusher 200 pushes the main compression elastic section 111, the damping elastic section 112 can move synchronously with the main compression elastic section 111. In turn, the first end 1111 of the main compression elastic section 111 applies a force to the movable spring 120 to push the movable spring 120 toward the stationary spring 410.

[0064] See Figures 4 to 10 , Figure 10 for Figure 9 The diagram shows the force analysis of the interaction between the movable spring portion 100 and the stationary spring portion 40. When the electromagnetic drive structure 30 (not mentioned again below) drives the push card 200 to move to the left, the push card 200 can push the second end 1112 of the main pressure elastic segment 111. At this time, the push card 200 applies a first force F1 to the second end 1112 of the main pressure elastic segment 111. This first force F1 acts on the first end 1111 through the main pressure elastic segment 111, so that the first force F1 can push the movable spring 120 to move to the left in the direction of the stationary spring 410.

[0065] Meanwhile, since the main pressure elastic segment 111 is connected to the second end 1112 through the first end 1111, when the second end 1112 of the main pressure elastic segment 111 moves to the left under the first force F1, the main pressure elastic segment 111 can apply the same reaction force to the damping elastic segment 112 through the first end 1111. Under the action of this reaction force, the second part 1122 of the damping elastic segment 112 can move away from the moving spring 120 to abut against the moving spring lead-out piece 130. Then, the moving spring lead-out piece 130 can apply a second force F2, which is opposite to the reaction force, to the second part 1122 of the damping elastic segment 112.

[0066] The second force F2 is transmitted to the first end 1111 of the main pressure elastic section 111 through the damping elastic section 112 and its first part 1121. At this time, the first force F1 and the second force F2 form a resultant force F at the first end 1111 of the main pressure elastic section 111. The resultant force F acts on the moving spring 120 to push the moving spring 120 toward the stationary spring 410, thereby causing the moving contact 140 to contact the stationary contact 420.

[0067] Understandably, compared to applying the first force F1 to the moving spring 120 solely through the main compression elastic segment, the compression spring 110 of this application adds a damping elastic segment 112 to the main compression elastic segment 111. In addition to the main compression elastic segment 111 applying the first force F1 to the moving spring 120, the damping elastic segment 112 also applies a second force F2 to the moving spring 120. The resultant force F formed by the first force F1 and the second force F2 is the pushing force of the compression spring 110 to push the moving spring 120.

[0068] This greatly increases the pushing force of the spring 110 on the moving spring 120 when the pusher 200 pushes the spring 110, allowing the moving spring 120 to move quickly toward the stationary spring 410, thereby enabling the moving contact 140 to quickly contact the stationary contact 420. At the same time, it also increases the contact force between the moving contact 140 and the stationary contact 420 to overcome the repulsive force between the moving contact 140 and the stationary contact 420, ensuring reliable contact between the moving contact 140 and the stationary contact 420.

[0069] Furthermore, the push card 200 can apply a first force F1 of different magnitudes to the second end 1112 of the main pressure elastic segment 111. The main pressure elastic segment 111 can apply a corresponding reaction force to the damping elastic segment 112 through the first end 1111, thereby the moving spring lead-out piece 130 can generate a second force F2 of corresponding magnitude on the second part 1122 of the damping elastic segment 112. In other words, the magnitude of the second force F2 applied by the moving spring lead-out piece 130 to the damping elastic segment 112 is related to the first force F1 received by the second end 1112 of the main pressure elastic segment 111.

[0070] In this way, the magnitude of the first force F1 applied by the push card 200 to the main pressure elastic section 111 can be adjusted, and the magnitude of the second force F2 applied to the damping elastic section 112 can be dynamically adjusted, thereby adjusting the magnitude of the pushing force applied by the compression spring 110 to the moving spring 120, so that the moving spring 120 moves quickly toward the stationary spring 410, achieving the purpose of rapid engagement between the moving contact 140 and the stationary contact 420.

[0071] Thus, the compression spring 110 of this application adopts the form of direct connection between the main compression elastic section 111 and the damping elastic section 112, which increases the pushing force of the compression spring 110 on the moving spring 120, so that the moving spring 120 moves quickly toward the stationary spring 410, so that the moving contact 140 on the moving spring 120 quickly contacts the stationary contact 420 on the stationary spring 410, and increases the contact force between the moving contact 140 and the stationary contact 420, resisting the repulsive force between the moving contact 140 and the stationary contact 420, so that the moving contact 140 and the stationary contact 420 can make reliable contact, and realize the rapid compression of the moving spring 120.

[0072] See Figure 7 and Figure 8 In one embodiment, the main pressure elastic segment 111 and the damping elastic segment 112 are an integral structure. That is, the main pressure elastic segment 111 and the damping elastic segment 112 are integrally formed, which ensures the structural strength at the connection between the main pressure elastic segment 111 and the damping elastic segment 112 and prevents breakage at the connection. Of course, in other embodiments of this application, the main pressure elastic segment 111 and the damping elastic segment 112 can also be separate components, and a reliable connection can be achieved through welding or other methods.

[0073] See Figures 4 to 6 In this application, the first end 1111 of the main pressure elastic segment 111 engages with the movable spring 120, and the second part 1122 of the damping elastic segment 112 engages with the movable spring lead-out piece 130. It is understood that this engagement can be abutment or connection; further, the engagement can be a movable connection or a fixed connection. For example, the main pressure elastic segment 111 is connected to the movable spring 120, and the damping elastic segment 112 abuts against the movable spring lead-out piece 130; or, the main pressure elastic segment 111 is connected to the movable spring 120, and the damping elastic segment 112 is connected to the movable spring lead-out piece 130, etc.

[0074] In principle, the connection form of the compression spring 110 with the movable spring plate 120 and the movable spring lead plate 130 is not limited, as long as the compression spring 110 can be combined with the movable spring plate 120 and the movable spring lead plate 130 so that the movable spring lead plate 130 can generate a second force F2 on the damping spring section. Several connection forms of the compression spring 110 with the movable spring and the movable spring lead plate 130 are introduced later, but the connection forms of the compression spring 110 with the movable spring and the movable spring lead plate 130 are not limited to the following and can also be other forms.

[0075] See Figures 4 to 10 In the first embodiment of this application, the first end 1111 of the main pressure elastic segment 111 is movably connected to the movable spring 120, and the second part 1122 of the damping elastic segment 112 can abut against or disengage from the movable spring lead-out piece 130. When the pusher 200 pushes the second end 1112 of the main pressure elastic segment 111, the first end 1111 of the main pressure elastic segment 111 can apply a first force F1 to the movable spring 120. At the same time, the first end 1111 of the main pressure elastic segment 111 can move relative to the movable spring 120. The main pressure elastic segment 111 drives the damping elastic segment 112 to move through the first end 1111, so that the movable spring lead-out piece 130 applies a second force F2 to the damping elastic segment 112.

[0076] See Figure 11 In the second embodiment of this application, the first end 1111 of the main pressure elastic segment 111 is fixedly connected to the moving spring 120, and the second part 1122 of the shock-absorbing elastic segment 112 can abut against or disengage from the moving spring lead-out piece 130. Figure 11 for Figure 6 The shown front view of the movable spring portion 100, which uses the compression spring 110 and stationary spring portion 40 of the second embodiment, is illustrated. In this embodiment, one end of the main compression elastic segment 111 is fixedly connected to the movable spring piece 120. Thus, when the pusher 200 pushes the second end 1112 of the main compression elastic segment 111, the main compression elastic segment 111 can apply a first force F1 to the movable spring piece 120 through the first end 1111. The main compression elastic segment 111 can also drive the second part 1122 of the damping elastic segment 112 to abut against the movable spring lead-out piece 130 through the first end 1111, so that the movable spring lead-out piece 130 can apply a second force F2 to the second part 1122 of the damping elastic segment 112.

[0077] See Figure 12 In the third embodiment of this application, the first end 1111 of the main pressure elastic segment 111 abuts against the moving spring 120, and the second part 1122 of the shock-absorbing elastic segment 112 is movably connected to the moving spring lead-out piece 130. Figure 12 for Figure 6 The shown front view of the movable spring portion 100, which uses the compression spring 110 and the stationary spring portion 40 of the third embodiment, is illustrated. In this embodiment, one end of the main compression elastic segment 111 abuts against the movable spring sheet 120, and one end of the damping elastic segment 112 is movably connected to the movable spring lead-out sheet 130. Thus, when the pusher 200 pushes the second end 1112 of the main compression elastic segment 111, the main compression elastic segment 111 applies a first force F1 to the movable spring sheet 120 through its first end 1111. At the same time, the main compression elastic segment 111 also applies force to the damping elastic segment 112 through its first end 1111, enabling the movable spring lead-out sheet 130 to apply a second force F2 to the second part 1122 of the damping elastic segment 112.

[0078] See Figure 13 In the fourth embodiment of this application, the first end 1111 of the main pressure elastic segment 111 abuts against the moving spring 120, and the second part 1122 of the shock-absorbing elastic segment 112 is fixedly connected to the moving spring lead-out piece 130. Figure 13 for Figure 6 The shown front view of the movable spring portion 100, which uses the compression spring 110 and the stationary spring portion 40 of the fourth embodiment, is illustrated. In this embodiment, one end of the main compression elastic segment 111 abuts against the movable spring sheet 120, and one end of the damping elastic segment 112 is fixed to the movable spring lead-out sheet 130. Thus, when the pusher 200 pushes the second end 1112 of the main compression elastic segment 111, the main compression elastic segment 111 applies a first force F1 to the movable spring sheet 120 through its first end 1111. At the same time, the main compression elastic segment 111 also applies force to the damping elastic segment 112 through its first end 1111, enabling the movable spring lead-out sheet 130 to apply a second force F2 to the second part 1122 of the damping elastic segment 112.

[0079] It is worth noting that the compression spring 110 in the second, third, and fourth embodiments is a variation of the compression spring 110 in the first embodiment, and its working principle and force application process are essentially the same as those of the compression spring 110 in the first embodiment. The following text only describes the structure and engagement method of the compression spring 110 in each embodiment. When describing the working principle and force application process of the compression spring 110, only the compression spring 110 in the first embodiment will be used as an example.

[0080] See Figures 4 to 13 In one embodiment, the main pressure elastic segment 111 includes a first connecting segment 1113, a bent segment 1114, and a main pressure segment 1115. The first connecting segment 1113 is engaged with the movable spring 120. The bent segment 1114 bends to connect the first connecting segment 1113 and the main pressure segment 1115, and the main pressure segment 1115 extends in a direction away from the movable spring 120. The first connecting segment 1113 is the component that combines the main pressure elastic segment 111 and the movable spring 120, and the main pressure segment 1115 is the main component of the main pressure elastic segment 111. One end of the bent segment 1114 is connected to the main pressure segment 1115, and the other end is connected to the first connecting segment 1113. The bent segment 1114 is bent relative to the first connecting segment 1113 and the main pressure segment 1115.

[0081] The bending section 1114 allows the first connecting section 1113 to be at a certain angle, facilitating the first connecting section 1113 to fit against the surface of the movable spring 120, thereby facilitating the engagement of the main pressure elastic section 111 with the movable spring 120. Furthermore, the bending section 1114 also enables the transmission of force to the main pressure section 1115. Due to the bent design of the bending section 1114, when the pusher 200 pushes the main pressure section 1115, the main pressure section 1115 can apply force to the first connecting section 1113 through the bending section, thereby applying the first force F1 to the movable spring 120. Simultaneously, the main pressure section 1115 also applies force to the damping elastic section 112 through the bending section 1114 and the first connecting section 1113, causing the movable spring lead-out piece 130 to apply a second force F2 to the damping elastic section 112.

[0082] In one embodiment, the first connecting segment 1113, the bending segment 1114, and the main pressing segment 1115 are an integral structure. That is, the first connecting segment 1113, the bending segment 1114, and the main pressing segment 1115 are integrally formed, which ensures the structural strength of the first connecting segment 1113, the bending segment 1114, and the main pressing segment 1115 at the connection point and prevents breakage at the connection. Of course, in other embodiments of this application, the first connecting segment 1113, the bending segment 1114, and the main pressing segment 1115 can also be separately arranged and reliably connected by means of adhesive bonding, welding, or other methods.

[0083] See Figures 4 to 11 In one embodiment, the first connecting segment 1113 is connected to the movable spring 120, and the second part 1122 of the shock-absorbing elastic segment 112 can abut against or disengage from the movable spring lead-out piece 130. In the first and second embodiments of this application, the main pressure elastic segment 111 is connected to the movable spring 120 through the first end 1111. When the push card 200 pushes the compression spring 110 toward the stationary spring 410, the push card 200 can push the main pressure segment 1115 of the main pressure elastic segment 1111. The main pressure segment 1115 is pushed by a first force F1. The main pressure segment 1115 transmits the first force to the first connecting segment 1113 through the bending segment 1114, and then acts on the movable spring 120 through the first connecting segment 1113.

[0084] Simultaneously, when the pusher 200 pushes the main pressure section 1115, it also drives the second part 1122 of the damping elastic section 112 towards the moving spring lead-out piece 130 through the bending section 1114 and the first connecting section 1113. The second part 1122 of the damping elastic section 112 gradually approaches the moving spring lead-out piece 130. When the second part 1122 of the damping elastic section 112 abuts against the moving spring lead-out piece 130, the moving spring lead-out piece 130 applies a second force F2 to the second part 1122 of the damping elastic section 112. The damping elastic section 112 can transmit the second force F2 to the first connecting section 1113. Then, the first force F1 and the second force F at the first connecting section 1113 form a resultant force F, which pushes the moving spring piece 120 towards the stationary spring piece 410.

[0085] See Figures 4 to 10 In the first embodiment of this application, the main compression elastic segment 111 further includes a mounting segment 1116. The mounting segment 1116 is disposed on the first connecting segment 1113. The movable spring 120 has a mounting hole. The mounting segment 1116 is inserted into the mounting hole and can move within the mounting hole. The mounting segment 1116 protrudes from the first connecting segment 1113 and extends toward the movable spring 120. The mounting segment 1116 can be inserted into the mounting hole to movably connect the main compression elastic segment 111 to the movable spring 120. It should be noted that the size of the mounting segment 1116 can be slightly larger than the size of the mounting hole. The mounting segment 1116 is inserted into the mounting hole with an interference fit, so that the mounting segment 1116 is fixed to the movable spring 120, ensuring the reliability of the connection between the compression spring 110 and the movable spring 120.

[0086] After the main compression elastic section 111 is inserted into the mounting hole of the movable spring 120 through the mounting section 1116, the main compression elastic section 111 and the damping elastic section 112 can swing relative to the movable spring 120, facilitating the contact 140 on the movable spring 120 to contact or separate from the stationary contact 420 on the stationary spring 410. The specific working principle of the compression spring 110 in this embodiment will be explained later. Optionally, the mounting section 1116 and the first connecting section 1113 are an integral structure.

[0087] See Figures 4 to 6 , Figure 11In the second embodiment of this application, the compression spring 110 further includes a first fastener 114, which passes through the first connecting section 1113 and is mounted on the movable spring plate 120 to fix the main compressive elastic section 111 to the movable spring plate 120. In this embodiment, the first connecting section 1113 is fixedly mounted to the movable spring plate 120 by the first fastener 114 to fix the main compressive elastic section 111 to the surface of the movable spring plate 120 facing the movable spring lead-out piece 130. Optionally, the first fastener 114 is a rivet, that is, the first connecting section 1113 is fixed to the movable spring plate 120 by riveting. Of course, in other embodiments of this application, the first fastener 114 may also be a screw or other structure capable of fixing the first connecting section 1113 to the movable spring plate 120.

[0088] See Figures 4 to 6 , Figure 12 and Figure 13 In one embodiment, the first connecting segment 1113 abuts against the movable spring 120, and the compression spring 110 further includes a fixing member that mounts the second part 1122 of the damping elastic segment 112 to the movable spring lead-out piece 130. In the third and fourth embodiments of this application, the main compression elastic segment 111 abuts against the surface of the movable spring 120 toward the movable spring lead-out piece 130 via the first connecting segment 1113, and the second part 1122 of the damping elastic segment 112 is mounted to the movable spring lead-out piece 130 via the fixing member.

[0089] When the pusher 200 pushes the compression spring 110 toward the stationary spring 410, the pusher 200 can push the main pressure section 1115 of the main pressure elastic section 111. The main pressure section 1115 is pushed by the first force F1. The main pressure section 1115 transmits the first force F1 to the first connecting section 1113 through the bending section 1114, and then acts on the moving spring 120 through the first connecting section 1113. At the same time, when the push card 200 pushes the main pressure section 1115, it also drives the second part 1122 of the damping elastic section 112 to abut against the moving spring lead-out piece 130 through the bending section 1114 and the first connecting section 1113. At this time, the moving spring lead-out piece 130 applies a second force F2 to the second part 1122 of the damping elastic section 112. The damping elastic section 112 can transmit the second force F2 to the first connecting section 1113. Then, the first force F1 and the second force F at the first connecting section 1113 form a resultant force F, which pushes the moving spring piece 120 toward the stationary spring piece 410.

[0090] See Figures 4 to 6 , Figure 12In the third embodiment of this application, the fixing component further includes a rotating member 115 and a support base 116. The support base 116 is disposed on the moving spring lead-out piece 130, and the rotating member 115 is disposed on the second part 1122 of the damping elastic segment 112 and rotatably mounted on the support base 116. Optionally, the rotating member 115 is a rotating shaft. The second part 1122 of the damping elastic segment 112 is rotatably mounted on the support base 116 via the rotating member 115, so that the second part 1122 of the damping elastic segment 112 is rotatably mounted on the support base 116.

[0091] See Figures 4 to 6 , Figure 13 In the fourth embodiment of this application, the compression spring 110 further includes a second fastener 117, which passes through the second portion 1122 of the damping elastic segment 112 and is mounted on the movable spring lead-out piece 130. In this embodiment, the second portion 1122 of the damping elastic segment 112 is fixed to the movable spring lead-out piece 130 by the second fastener 117, thereby fixing the damping elastic segment 112 to the surface of the movable spring lead-out piece 130 facing the movable spring piece 120. Optionally, the second fastener 117 is a rivet, that is, the damping elastic segment 112 is fixed to the movable spring piece 120 by riveting. Of course, in other embodiments of this application, the second fastener 117 may also be a screw or other structure capable of fixing the damping elastic segment 112 to the movable spring lead-out piece 130.

[0092] See Figures 5 to 11 In one embodiment, the damping elastic segment 112 includes a second connecting segment 1123 and a transition segment 1124. The second connecting segment 1123 is connected to the first end 1111 of the main pressure elastic segment 111 and extends toward the moving spring lead-out piece 130. The transition segment 1124 transitionally connects to the end of the second connecting segment 1123 away from the first connecting segment 1113, and the transition segment 1124 can engage the moving spring lead-out piece 130.

[0093] The second connecting section 1123 is the main component of the damping elastic section 112, and the transition section 1124 is where the damping elastic section 112 engages with the moving spring lead-out piece 130 and can connect to the second connecting section 1123. One end of the second connecting section 1123 is connected to the first connecting section 1113, and the other end of the second connecting section 1123 is connected to the transition section 1124. The transition section 1124 is recessed upwards to facilitate the engagement of the damping elastic section 112 with the moving spring lead-out piece 130.

[0094] Thus, when the pusher 200 pushes the second end 1112 of the main pressure elastic section 111, the first force F1 on the second end 1112 of the main pressure elastic section 111 can be transmitted to the first connecting section 1113 and act on the moving spring 120. At the same time, the main pressure elastic section 111 can also drive the second connecting section 1123 and the transition section 1124 toward the moving spring lead-out piece 130 through the first connecting section 1113. At this time, the moving spring lead-out piece 130 presses against the transition section 1124 to apply a second force F2 to the transition section 1124. The second force F2 is transmitted to the first connecting section 1113 through the second connecting section 1123 and acts on the moving spring 120.

[0095] See Figures 7 to 11 In the first and second embodiments of this application, the damping elastic segment 112 abuts against or disengages from the moving spring lead-out piece 130 via the transition segment 1124. Initially, the transition segment 1124 is disengaged from the moving spring lead-out piece 130, with a certain distance between them. When the pusher 200 pushes the main pressure elastic segment 111 toward the stationary spring piece 410, the main pressure elastic segment 111 applies a first force F1 to the moving spring piece 120. Simultaneously, as the main pressure elastic segment 111 drives the damping elastic segment 112 toward the moving spring lead-out piece 130, the transition segment 1124 gradually approaches the moving spring lead-out piece 130. When the transition segment 1124 abuts against the moving spring lead-out piece 130, the moving spring lead-out piece 130 applies a second force F2 to the transition segment 1124.

[0096] In other words, when the pusher 200 first applies the first force F1 to the main pressure elastic section 111, the moving spring lead-out piece 130 initially does not apply the second force F2 to the damping elastic section 112. At this time, only the compression spring 110 pushes the moving spring piece 120 under the action of the first force F1. After a period of time, the damping elastic section 112 abuts against the moving spring lead-out piece 130 through the transition section 1124, and the moving spring lead-out piece 130 applies the second force to the damping elastic section 112. At this time, the compression spring 110 pushes the moving spring piece 120 under the action of the first force F1 and the second force F2.

[0097] In the third and fourth embodiments of this application, the damping elastic segment 112 can be connected to the rotating member 115 or the third fastener via the transition segment 1124. Of course, the transition segment 1124 can also be flattened or modified into other forms to facilitate the connection of the damping elastic segment 112 to the rotating member 115 or the third fastener. When the pusher 200 pushes the main pressure elastic segment 111 toward the stationary spring 410, the main pressure elastic segment 111 applies a first force F1 to the moving spring 120. At the same time, the main pressure elastic segment 111 drives the damping elastic segment 112 toward the moving spring lead-out piece 130. At this time, the moving spring lead-out piece 130 directly applies a second force F2 to the transition segment 1124.

[0098] In one embodiment, the second connecting segment 1123 and the transition segment 1124 are an integral structure. That is, the second connecting segment 1123 and the transition segment 1124 are manufactured using a one-piece molding method. This ensures the structural strength of the connection between the second connecting segment 1123 and the transition segment 1124, preventing breakage at the connection point. Of course, in other embodiments of this application, the second connecting segment 1123 and the transition segment 1124 can also be separately disposed and connected by welding or other methods.

[0099] See Figure 7 In one embodiment, the main compression elastic segment 111 has four first ends 1111, and the number of damping elastic segments 112 is two. The two damping elastic segments 112 are connected to two of the first ends 1111, and the other two first ends 1111 engage with the movable spring 120. Two of the four first ends 1111 are connected to the first portions 1121 of the two damping elastic segments 112, and the other two first ends 1111 engage with the movable spring 120. This improves the reliability of the connection between the compression spring 110 and the movable spring 120.

[0100] See Figures 4 to 10 In this application, the compression spring 110 adopts a direct connection between the main compression elastic segment 111 and the damping elastic segment 112. When the pusher 200 pushes the second end 1112 of the main compression elastic segment 111 to the left, the pusher 200 applies a first force F1 to the second end 1112 of the main compression elastic segment 111. This first force F1 acts on the first end 1111 through the main compression elastic segment 111. At the same time, the main compression elastic segment 111 can apply the same reaction force to the damping elastic segment 112 through the first end 1111. Under the action of this reaction force, the second part 1122 of the damping elastic segment 112 can gradually approach the moving spring lead-out piece 130. At this time, the moving spring piece 120 is only pushed to the left towards the stationary spring piece 410 under the action of the first force F1.

[0101] When the pusher 200 pushes the main pressure elastic section 111 for a period of time, the second part 1122 of the damping elastic section 112 abuts against the moving spring lead-out piece 130. The moving spring lead-out piece 130 can apply a second force F2 opposite to the reaction force to the second part 1122 of the damping elastic section 112. The second force F2 is transmitted through the damping elastic section 112 to the first end 1111 of the main pressure elastic section 111. At this time, the first force F1 and the second force F2 form a resultant force F at the first end 1111 of the main pressure elastic section 111. The resultant force F acts on the moving spring piece 120 to push the moving spring piece 120 toward the stationary spring piece 410, thereby making the moving contact 140 contact the stationary contact 420.

[0102] Thus, when the pusher 200 pushes the movable spring 120 through the compression spring 110, initially the movable spring 120 is pushed only by the first force F1. Later, the movable spring 120 is pushed by the resultant force F of the first force F1 and the second force F2. In this way, the pushing force on the movable spring 120 suddenly increases, which enables the movable spring 120 to move quickly toward the stationary spring 410, thereby enabling the movable contact 140 to quickly contact the stationary contact 420. At the same time, it can also increase the contact force between the movable contact 140 and the stationary contact 420 to overcome the repulsive force between the movable contact 140 and the stationary contact 420, so as to make reliable contact between the movable contact 140 and the stationary contact 420.

[0103] See Figures 4 to 10 When the electromagnetic relay 1 is tested for short circuit resistance, the moving contact 140 on the moving reed 120 is short-circuited with the stationary contact 420 on the stationary reed 410. At this time, the current in the moving reed 120 increases, and the protrusion 121 on the moving reed 120 arches to the left. The moving reed 120 can drive the damping elastic section 112 to move to the left through the first end 1111 of the main pressure elastic section 111. At this time, the contact degree between the damping elastic section 112 and the moving spring lead 130 decreases, so as to reduce the second force F2 applied by the moving spring lead 130 to the damping elastic section 112. Because the damping elastic section 112 and the main pressure elastic section 111 are linked by force, the first force F1 on the main pressure elastic section 111 also decreases.

[0104] As the first force F1 on the main pressure elastic section 111 decreases, the moving contact 140 and the stationary contact 420 push the moving spring 120 to the right under the action of repulsion, so that the reaction force to the right will not increase rapidly. At this time, the moving spring 120 can drive the push card 200 to move to the right through the main pressure elastic section 111, and then the push card 200 can push the armature in the electromagnetic drive structure 30 to spring open, so as to avoid the failure of the electromagnetic drive structure 30 and ensure the performance of the electromagnetic drive structure 30.

[0105] In other words, when the electromagnetic relay 1 is tested for short circuit resistance, the second force F2 on the damping elastic section 112 decreases as the moving spring 120 moves the damping elastic section 112 to the left, which in turn reduces the first force F1 on the main pressure elastic section 111. Thus, when the moving contact 140 and the stationary contact 420 spring open under the action of repulsion, the reaction force will not increase rapidly due to the action of the first force F1 of the main pressure elastic section 111, and the armature will not fail to spring open.

[0106] See Figures 4 to 10When the electromagnetic drive structure 30 drives the push card 200 to pull the moving contact 140 on the moving spring 120 to separate from the stationary contact 420 on the stationary spring 410, the push card 200 begins to move to the right, and the second end 1112 of the main pressure elastic segment 111 disengages from the push card 200. That is, when the push card 200 begins to move to the right, the second end 1112 of the main pressure elastic segment 111 has not yet followed the movement of the push card 200. The first force F1 on the main pressure elastic segment 111 is at its minimum, and consequently the second force F2 on the shock-absorbing elastic segment 112 is also at its minimum. At this time, the pushing force on the moving spring 120 is also at its minimum, which can reduce the resistance to the separation of the moving contact 140 and the stationary contact 420, making it easier for the moving contact 140 and the stationary contact 420 to separate.

[0107] As the pusher 200 continues to move to the right, it contacts the movable spring 120. At this point, the pusher 200 pushes the movable spring 120 to move to the right, separating the movable contact 140 from the stationary contact 420. During this process, the movable spring 120 compresses the damping elastic segment 112. Simultaneously, the movable spring extension 130 applies a second force F2 to the damping elastic segment 112. As the movable contact 140 separates from the stationary contact 420, the second force F2 gradually increases. The second force F2 reaches its maximum when the gap between the movable contact 140 and the stationary contact 420 is at its maximum.

[0108] Because of the presence of the second force F2, the main pressure elastic segment 111 is prevented from swinging relative to the moving spring 120, thereby preventing the main pressure elastic segment 111 from exerting a pushing force on the moving spring 120 to cause the moving spring 120 to bounce back. This also prevents the moving contact 140 from contacting the stationary contact 420 when the electromagnetic relay 1 is disconnected, thus ensuring reliable disconnection of the electromagnetic relay 1. Furthermore, when the electromagnetic relay 1 is disconnected, the presence of the second force F2 overcomes the holding force of the armature, causing the armature to fail and reducing the resistance to the subsequent closing of the electromagnetic relay 1.

[0109] See Figures 3 to 6 This application also provides a mating structure 10, including a movable spring portion 100 and a pusher 200. The movable spring portion 100 includes a movable spring lead-out piece 130, a movable spring piece 120, a contact disposed on the movable spring piece 120, and a compression spring 110 as described in any of the above embodiments. One end of the movable spring piece 120 is disposed on the movable spring lead-out piece 130, and the other end is installed in the pusher 200. The compression spring 110 is disposed between the movable spring lead-out piece 130 and the movable spring piece 120. With the compression spring 110 of the above embodiments, the mating structure 10 of this application enables the movable contact 140 to quickly contact the stationary contact 420 and increases the contact force between the movable contact 140 and the stationary contact 420, ensuring reliable contact between them.

[0110] See Figures 1 to 10This application also provides an electromagnetic relay 1 including an electromagnetic drive structure 30, a stationary spring portion 40, and a mating structure 10 as described in the above embodiment. The electromagnetic drive structure 30 drives the pusher 200 in the mating structure 10 to move, causing the pusher 200 to bring the moving spring portion 100 in the mating structure 10 into contact with or separate from the stationary spring portion 40. With the above-described mating structure 10, the electromagnetic relay 1 of this application enables the moving contact 140 to quickly contact the stationary contact 420, increasing the contact force between the moving contact 140 and the stationary contact 420, thus ensuring reliable contact between them. Simultaneously, during short-circuit withstand testing, the armature in the electromagnetic drive structure 30 can reliably spring open, and when the electromagnetic relay 1 is disconnected, the rebound of the moving contact 140 is reduced, and the resistance to subsequent closure of the electromagnetic relay 1 is decreased.

[0111] 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.

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.
