Flexible structures, moving contact components, and relays

Abstract

This application provides an elastic structure, a moving contact assembly, and a relay. A first elastic element is configured to connect a moving contact and a pushing element of the relay. A third elastic element is configured to elastically contact at least one of the first elastic element and the moving contact. The moving contact is configured to reciprocate between a closed position and an open position. The third elastic element is configured to apply a force suitable for the moving contact to move toward the closed position to at least one of the first elastic element and the moving contact. Since the third elastic element can generate a more significant elastic force whether the moving contact enters an overtravel state before or after contact with the stationary contact, it provides a better elastic force effect. Therefore, when the moving contact simultaneously has a current-carrying contact and an arcing contact, the third elastic element can be used to stably achieve "closing before opening" of the arcing contact, thereby ensuring the stability of the contact resistance of the current-carrying contact.

Description

Technical Field

[0001] This application relates to the field of electronic control device technology, and in particular to elastic structures, moving contact components, and relays. Background Technology

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

[0003] When the relay is working, the pushing element applies a pushing force to the moving contact, causing the moving contact to move from the open position to the closed position, and then make closed contact with the stationary contact. In order to control arcing and improve the stability of contact resistance, the moving contact of the moving contact is divided into an arcing contact and a current-carrying contact. When the arcing contact and the current-carrying contact are in closed contact, they respectively make contact with different stationary contacts of the stationary contact, and the arcing contact and the current-carrying contact are controlled to not close or open with the stationary contact at the same time.

[0004] At this time, since the arc will be concentrated on the first contacting arcing contact to burn when closing, and also concentrated on the last contacting arcing contact to burn when breaking, it can be ensured that the arcing contact is "closed first and then broken". Only the arcing contact is used to generate erosion, and the current-carrying contact is not used to generate erosion, thereby ensuring the stability of the contact resistance of the current-carrying contact.

[0005] However, the existing technology mainly ensures that the arcing contact and the current-carrying contact form different gaps with the corresponding stationary contact. This design scheme with different gaps cannot effectively guarantee that the arcing contact will "close first and then break", which is a technical problem that urgently needs to be solved in this field.

[0033] In one embodiment, at least two unit elastic elements include a first unit elastic element and a second unit elastic element;

[0036] In one embodiment, the number of moving contacts is configured to be at least two, at least one of the moving contacts being provided with a current-carrying contact and at least one of the moving contacts being provided with an arc-ignition contact, the first unit elastic element being configured to connect to the moving contact providing the current-carrying contact, and the second unit elastic element being configured to connect to the moving contact providing the arc-ignition contact.

[0037] This application provides a dynamic contact assembly, the dynamic contact assembly comprising:

[0038] At least one of the moving contact and the pushing component;

[0039] The elastic structure, wherein the first elastic element of the elastic structure is configured to connect at least one of the moving contact and the pushing element.

[0040] In one embodiment, the number of moving contacts is configured to be at least two, at least one of the moving contacts being provided with an arcing contact and at least one of the moving contacts being provided with a current-carrying contact.

[0041] In one embodiment, at least two of the moving contacts include a first moving contact and a second moving contact, the first moving contact being provided with at least one arcing contact and the second moving contact being provided with at least one current-carrying contact.

[0042] This application provides a relay, the relay comprising:

[0043] Base;

[0044] A static contact assembly, wherein the static contact assembly is disposed on the base, and the static contact assembly includes a static contact element;

[0045] The moving contact assembly has a moving contact element that is not in direct contact with the base;

[0046] The magnetic circuit section is configured to drive the moving contact to switch between a closed position and an open position. When moving from the open position to the closed position, the moving contact moves toward the stationary contact. When moving from the closed position to the open position, the moving contact moves away from the stationary contact.

[0047] In one embodiment, the drive mechanism of the magnetic circuit section is configured as a rotary drive mechanism, a direct-acting drive mechanism, a snap-action drive mechanism, or a motor drive mechanism; and / or,

[0048] The moving contact has an extending direction, and the moving contact has moving contacts at both ends along its extending direction. The moving contacts are configured to contact the stationary contacts of the stationary contact, wherein the moving contacts are configured as arcing contacts or current-carrying contacts.

[0049] In the aforementioned elastic structure, moving contact assembly, and relay, the third elastic element can generate a more significant elastic force, providing a better elastic force effect, whether the moving contact enters an overtravel state before or after contact with the stationary contact. Therefore, when the moving contact simultaneously has both current-carrying and arc-ignition contacts, the third elastic element can be used to stably achieve "closing before breaking" of the arc-ignition contact, thereby ensuring the stability of the contact resistance of the current-carrying contact.

[0050] When the moving contact closes relative to the stationary contact, the third elastic element, with its superior elastic force, ensures that the arcing contact of the moving contact and the stationary contact of the stationary contact close first. Upon closure, the arc concentrates on the first contacting arcing contact, causing it to burn. Simultaneously, the elastic force of the third elastic element is not applied between the current-carrying contact of the moving contact and the stationary contact of the stationary contact. Therefore, upon closure, the current-carrying contact of the moving contact and the stationary contact of the stationary contact can close relatively later, preventing the current-carrying contact from burning.

[0051] Similarly, when the moving contact disconnects relative to the stationary contact, the third elastic element applies an elastic force suitable for keeping the arcing contact of the moving contact and the stationary contact of the stationary contact closed. At this time, the current-carrying contact of the moving contact and the stationary contact of the stationary contact will disconnect first, preventing ablation of the current-carrying contact. The elastic force of the third elastic element ensures that the arcing contact of the moving contact and the stationary contact of the stationary contact disconnect later, concentrating the arc at the later-disconnecting arcing contact and causing ablation.

[0052] Therefore, the above technical solution does not simply use the gap difference design to ensure that the arcing contact "closes first and then breaks". Instead, based on the gap difference design, the elastic force of the third elastic element is used to achieve the arcing contact "closes first and then breaks". This structural design can more stably achieve the arcing contact "closes first and then breaks", thereby ensuring the stability of the contact resistance of the current-carrying contact.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] See Figures 1 to 7 As shown, this application provides a relay, which includes a base 10, a moving contact assembly 20, a stationary contact assembly 30, and a magnetic circuit portion, among other structures. Figure 1 and Figure 2 As shown, the base 10 serves as the assembly foundation for structures such as the moving contact assembly 20, the stationary contact assembly 30, and the magnetic circuit. The shape, material, and size of the base 10 can be designed according to actual needs and are not limited here. For example, the base 10 may have an internal cavity for assembly, and the moving contact assembly 20 and the stationary contact assembly 30 may be disposed in the internal cavity of the base 10. The moving contact assembly 20 includes at least one moving contact element 200, and the moving contact element 200 may be provided with at least one moving contact point 210. The stationary contact assembly 30 includes at least one stationary contact element 31, and the stationary contact element 31 may be provided with at least one stationary contact point 32.

[0092] Continue reading Figures 4 to 7As shown, the magnetic circuit portion (not shown) can be configured to drive the moving contact 200 to switch between a closed position 500 and an open position 600. Figure 4 and Figure 5 As shown, the disconnected position 600 means that the moving contact 200 is in contact with the stationary contact 31. Figure 6 and Figure 7 As shown, the closed position 500 is the position where the moving contact 200 is separated from the stationary contact 31. Under the control of the magnetic circuit, when the moving contact 200 moves from the open position 600 to the closed position 500, the moving contact 200 can... Figure 4 and Figure 5 As shown, it moves downward toward the stationary contact 31, transforming into... Figure 6 and Figure 7 The closed state is shown. When the moving contact 200 moves from the closed position 500 to the open position 600, the moving contact 200 can be as follows: Figure 6 and Figure 7 As shown, the upward movement away from the stationary contact 31 is converted into... Figure 4 and Figure 5 The disconnected state is shown.

[0093] When the magnetic circuit section (not shown) drives the moving contact 200 to switch between the closed position 500 and the open position 600, the moving contact 200 of the moving contact assembly 20 can be configured to be in direct contact with the base 10 or in a non-direct contact state. For example, when the moving contact 200 is in direct contact with the base 10, a portion of the moving contact 200 can be connected to the base 10, and another portion of the moving contact 200 can move between the closed position 500 and the open position 600 under the control of the magnetic circuit section. Alternatively, when the moving contact 200 is in a non-direct contact state with the base 10, the moving contact 200 can be completely disconnected from the base 10, and the entire moving contact 200 can move between the closed position 500 and the open position 600 under the control of the magnetic circuit section, i.e. Figures 1 to 7 The structural design shown is flexible and can be adapted to different needs; no specific design is required here.

[0094] The drive mechanism of the aforementioned magnetic circuit can be configured as a rotary drive mechanism, a direct-acting drive mechanism, a snap-action drive mechanism, a motor drive mechanism, or other types of drive mechanisms, without limitation. Specifically, the rotary drive mechanism is a rotary magnetic circuit, which utilizes a permanent magnet to provide continuous magnetic flux and changes the magnetic flux path by rotating the magnetically guiding component, thereby achieving bistable switching (closing or opening) of the moving contact 210 and the stationary contact 32. The direct-acting drive mechanism is a direct-acting magnetic circuit, which utilizes a permanent magnet to provide continuous magnetic flux and changes the magnetic flux path by a linearly moving magnetically guiding component, thereby achieving bistable switching (closing or opening) of the moving contact 210 and the stationary contact 32. The motor drive mechanism generates a transient magnetic field through coil pulse current, which superimposes or cancels the magnetic field of the permanent magnet, breaking the original magnetic circuit balance and driving the mechanical component (rotating rotor or linear moving iron core) to move, thereby achieving bistable switching (closing or opening) of the moving contact 210 and the stationary contact 32.

[0095] See Figure 8 As shown in Figure 11, regarding the aforementioned moving contact assembly 20, the moving contact assembly 20 may include at least one of a moving contact element 200 and a pushing element 300, for example, simultaneously including a moving contact element 200 and a pushing element 300 that cooperate with each other. The elastic structure 100 is mainly used to provide an elastic connection, for example... Figure 8 and Figure 9 As shown, the first elastic member 1000 included in the elastic structure 100 can be configured to connect at least one of the moving contact member 200 and the pusher member 300. For example, a portion of the first elastic member 1000 is connected to the moving contact member 200 and another portion is connected to the pusher member 300, such that the first elastic member 1000 is elastically connected between the moving contact member 200 and the pusher member 300.

[0096] The moving contact 200 has an extending direction, and moving contacts 210 are respectively provided at both ends of the moving contact 200 along its extending direction, so that the moving contact 200 is configured as a conductive bridge structure. The moving contacts 210 of the moving contact 200 can be configured as stationary contacts 32 for contacting the stationary contact 31. Among them, the moving contacts 210 can be configured as arcing contacts 212 or current-carrying contacts 211. The arcing contacts 212 mainly function to disconnect and connect the load circuit. The current-carrying contacts 211 mainly function to shunt current after the circuit is connected. The contact gap between the arcing contact 212 and the stationary contact 32 is smaller than the contact gap between the current-carrying contact 211 and the stationary contact 32 in the assembly design. Therefore, when the relay switches between the closed and open states, the arcing contact 212 and the stationary contact 32 need to close first and then open. Correspondingly, the current-carrying contact 211 and the stationary contact 32 need to close later and open first.

[0097] For example, the number of moving contacts 200 can be configured to be at least two. Therefore, at least one moving contact 200 can set the moving contact 210 as an arcing contact 212, and at least one moving contact 200 can set the moving contact 210 as a current-carrying contact 211. In one embodiment, the at least two moving contacts 200 may include a first moving contact 200 and a second moving contact 200. The first moving contact 200 is provided with at least one current-carrying contact 211, and the second moving contact 200 is provided with at least one arcing contact 212. For example, the number of moving contacts 200 can be configured to be two, namely a first moving contact 200 and a second moving contact 200. Both the first moving contact 200 and the second moving contact 200 can be configured as the aforementioned moving conductive bridge structure, having an extending direction. In this case, the first moving contact 200 can set two moving contacts 210 as arcing contacts 212, and the second moving contact 200 can set two moving contacts 210 as current-carrying contacts 211. Those skilled in the art can choose a suitable structural design based on actual needs, and no restrictions are imposed here.

[0098] Regarding the aforementioned elastic structure 100, the elastic structure 100 may include a first elastic element 1000, and the elastic structure 100 may also be provided with a second elastic element 2000 or a third elastic element 3000 that can cooperate with the first elastic element 1000, as needed. For example, see [reference needed]. Figure 10 As shown, the elastic structure 100 may include a first elastic element 1000, a second elastic element 2000, and a third elastic element 3000. Alternatively, see [reference needed]. Figure 11 As shown, the elastic structure 100 may include a first elastic element 1000 and a second elastic element 2000, but not a third elastic element 3000. Alternatively, the elastic structure 100 may include a first elastic element 1000 and a third elastic element 3000, but not a second elastic element 2000. Furthermore, those skilled in the art can choose other structural designs for the elastic structure 100 according to requirements, which are not limited here. The following will describe different embodiments of the elastic structure 100 mentioned above.

[0099] like Figure 12 As shown, the first elastic member 1000 may include a first support portion 1100 and a first elastic portion 1200 connected together. Both the first support portion 1100 and the first elastic portion 1200 are part of the structure of the first elastic member 1000, and their positions and dimensions within the first elastic member 1000 are determined based on their support and elastic functions. Specifically, the first support portion 1100 is configured to elastically contact the moving contact member 200, and the first elastic portion 1200 is configured to elastically contact the pushing member 300.

[0100] Second elastic element 2000 Figure 13 and Figure 14As shown, the second elastic member 2000 has a first contact portion 2110 and a second contact portion 2210. In one embodiment, the second elastic member 2000 may include a connected second support portion 2100 and a second elastic portion 2200. Both the second support portion 2100 and the second elastic portion 2200 are part of the structure of the second elastic member 2000, and their positions and sizes within the second elastic member 2000 are determined based on their support and elastic functions. The first contact portion 2110 may be located in the second support portion 2100, meaning the first contact portion 2110 is one or more portions of the second support portion 2100, and the second contact portion 2210 is located in the second elastic portion 2200, meaning the second contact portion 2210 is one or more portions of the second elastic portion 2200.

[0101] The first contact portion 2110 can be configured to elastically contact at least one of the first support portion 1100 and the moving contact member 200. For example, the first contact portion 2110 can elastically contact either the first support portion 1100 or the moving contact member 200, or it can elastically contact both the first support portion 1100 and the moving contact member 200 simultaneously. Meanwhile, the second contact portion 2210 can be configured to elastically contact at least one of the first elastic portion 1200 and the pushing member 300. For example, the second contact portion 2210 can elastically contact either the first elastic portion 1200 or the pushing member 300, or it can elastically contact both the first elastic portion 1200 and the pushing member 300 simultaneously.

[0102] Therefore, the second elastic member 2000 can form an elastic support force between the moving contact member 200 and the pushing member 300 based on its first contact portion 2110 and second contact portion 2210, thereby compensating for the insufficient support force of the first elastic member 1000. (Comparison) Figure 17 and Figure 18 It is known that without the second elastic element 2000, the second elastic element 2000 (existing leaf spring) has weak stiffness. During the process of the pusher 300 transmitting the force to the moving contact 200, it undergoes flexible deformation and insufficient support, which leads to its unstable structure and low force transmission efficiency.

[0103] Therefore, when the moving contact 200 closes with the stationary contact 31, the moving contact 200 is prone to contact bounce (i.e., after contacting the stationary contact 31, the moving contact 200 will bounce back in a direction away from the stationary contact 31). Contact bounce can lead to arcing, silver spatter, bonding, and welding. To solve this technical problem, this application adds a second elastic element 2000 to the elastic structure 100.

[0104] like Figure 17As shown, in one example embodiment, if the second elastic element 2000 is not provided, the elastic structure 100 will undergo significant deformation after being subjected to force between the pushing member 300 and the moving contact member 200, resulting in a reduction in the height of the elastic structure 100 to 4.86. This occurs when the elastic structure 100 includes the first elastic element 1000 and the second elastic element 2000, or when the elastic structure 100 includes the first elastic element 1000, the second elastic element 2000, and the third elastic element 3000. Adding the second elastic element 2000, as... Figure 18 As shown in the enumerated embodiment, after the elastic structure 100 is subjected to force between the pusher 300 and the moving contact 200, the height of the elastic structure 100 can be reduced to only 5.26.

[0105] It should be noted that the above two data are obtained in a single embodiment and are used to compare the elastic support effect provided by the second elastic element 2000. In other embodiments, they may be other specific values.

[0106] Based on the comparison of the two data, it can be seen that the second elastic element 2000 can provide additional elastic support force between the pusher 300 and the moving contact 200. This elastic support force can be applied by the pusher 300 towards the moving contact 200, so that when the moving contact 200 and the stationary contact 31 are in closed contact, the elastic support force can also be used to maintain the contact stability between the moving contact 200 and the stationary contact 31, resist the contact bounce mentioned above, and avoid situations such as arc burning, silver layer spatter bonding and welding.

[0107] During the movement of the moving contact 200 toward the stationary contact 31, after the moving contact 200 contacts the stationary contact 31, the pushing member 300 will continue to apply a certain amount of pressure to the moving contact 200, causing the moving contact 200 to further abut against the stationary contact 31. This allows the moving contact 200 to enter an overtravel state. That is, when the moving contact 200 moves between the closed position 500 and the open position 600, the first elastic member 1000 can be configured to enter the overtravel state when the moving contact 200 reaches the closed position 500.

[0108] In one embodiment, the first contact portion 2110 may be configured to always abut against at least one of the first support portion 1100 and the moving contact member 200 before entering the overtravel state. Simultaneously, the second contact portion 2210 may be configured to always abut against at least one of the first elastic portion 1200 and the pusher member 300 before entering the overtravel state. When the first contact portion 2110 or the second contact portion 2210 is in a state of constant abutment, the aforementioned elastic support force can always be applied between the pusher member 300 and the moving contact member 200 before entering the overtravel state. Therefore, at the moment the moving contact member 200 and the stationary contact member 31 make contact, the stability of the contact between the moving contact member 200 and the stationary contact member 31 can be maintained, avoiding the problem of contact bounce.

[0109] The first support portion 1100 may always be in direct or indirect contact with the moving contact member 200, or the first support portion 1100 may also be in direct or indirect contact with the moving contact member 200 when it is necessary to provide elastic support force. Similarly, the first elastic portion 1200 may always be in direct or indirect contact with the pushing member 300, or the first elastic portion 1200 may be in direct or indirect contact with the pushing member 300 when it is necessary to provide elastic support force. Therefore, in one embodiment, the first support portion 1100 may be configured to always be connected to the moving contact member 200, and the first elastic portion 1200 may be configured to always be connected to the pushing member 300.

[0110] The first contact portion 2110 can elastically contact the first support portion 1100 or the moving contact member 200 in various ways. For example, in one embodiment, the first contact portion 2110 can be configured to have at least one first contact area 2111 and at least one second contact area 2112, the first contact area 2111 being configured for elastic contact with the first support portion 1100, and the second contact area 2112 being configured for elastic contact with the moving contact member 200. (Continue reading) Figure 8 , Figure 13 and Figure 14 As shown, the first contact portion 2110 may have two first contact areas 2111 and one second contact area 2112, the second contact area 2112 being located between the two first contact areas 2111. Therefore, as Figure 8 As shown, two first contact areas 2111 can elastically contact the two first support portions 1100 of the first elastic member 1000 on both sides, and a second contact area 2112 can elastically contact the moving contact member 200 in the middle. In addition, those skilled in the art can use other elastic contact methods, which are not limited here.

[0111] In one embodiment, the first contact area 2111 of the first contact portion 2110 can elastically contact the first support portion 1100 when elastic support force is required, or it can be permanently fixedly connected by means of threads, snap-fit, etc. The second contact area 2112 of the first contact portion 2110 can elastically contact the moving contact member 200 when elastic support force is required, or it can be permanently fixedly connected by means of threads, snap-fit, etc. Moreover, in one embodiment, see further... Figure 8 and Figure 9 As shown, the second contact area 2112 of the first contact portion 2110 can also be configured to be indirectly connected to the moving contact member 200 via the moving magnetic conductor 400. In this case, the moving magnetic conductor 400 is disposed on the moving contact member 200, and the second contact area 2112 is fixedly connected to the moving magnetic conductor 400 by means of threads, snap-fit, etc., thereby being fixedly connected to the moving contact member 200.

[0112] Continue reading Figures 19 to 21 As shown, in one embodiment, the second elastic member 2000 may also adopt other structural designs. For example, the first contact portion 2110 may be configured to elastically contact at least one first force-bearing contact point 1110 of the first support portion 1100 or the moving contact member 200, and the second contact portion 2210 may be configured to elastically contact at least one second force-bearing contact point 1210 of the first elastic portion 1200 or the pushing member 300. Furthermore, a plane passing through the first force-bearing contact point 1110 and perpendicular to the movement direction of the moving contact member 200 may be defined as the first contact force-bearing surface 1111, and a plane passing through the second force-bearing contact point 1210 and perpendicular to the movement direction of the moving contact member 200 may be defined as the second contact force-bearing surface 1211. Therefore, the second elastic member 2000 may be positioned between the first contact force-bearing surface 1111 and the second contact force-bearing surface 1211, and the structure of the second elastic member 2000 may be designed in this manner.

[0113] At this point, the entire structure of the second elastic element 2000, after assembly, can be situated within the space enclosed between the first contact force-bearing surface 1111 and the second contact force-bearing surface 1211. This design allows the pusher 300 to transmit force to the moving contact 200 using the second elastic element 2000, ensuring that the elastic support force applied by the second elastic element 2000 between them can be directly transmitted from the pusher 300 to the moving contact 200 via the shortest path, thus guaranteeing the efficiency and effectiveness of the elastic support force transmission. This avoids the need for the second elastic element 2000 to traverse a reversible path when transmitting force between the pusher 300 and the moving contact 200, as in other structures, a reversible transmission path would result in the loss of the elastic support force applied by the second elastic element 2000, reducing the elastic support effect and consequently decreasing the resistance to contact bounce.

[0114] For example, see Figure 19As shown, if the first force-receiving contact 1110 is located at the moving contact 200, then the first contact portion 2110 can be configured to elastically contact the first force-receiving contact 1110 of the moving contact 200. If the second force-receiving contact 1210 is located at the first elastic portion 1200, then the second contact portion 2210 can be configured to elastically contact the second force-receiving contact 1210 of the first elastic portion 1200. Figure 19 As shown, at this time, the force-bearing surface 1111 of the first contact passes through the first force-bearing contact 1110 of the moving contact 200 and is perpendicular to the direction of movement of the moving contact 200; the force-bearing surface 1211 of the second contact passes through the second force-bearing contact 1210 of the first elastic part 1200 and is perpendicular to the direction of movement of the moving contact 200. Those skilled in the art can also select other first force-bearing contacts 1110 and second force-bearing contacts 1210 according to the force transmission requirements, which is not limited here.

[0115] In addition, the first contact portion 2110 can be configured to make multi-point contact with at least one of the first support portion 1100 and the moving contact member 200, that is, to simultaneously contact a plurality of first force-bearing contact points 1110. The second contact portion 2210 can also be configured to make multi-point contact with at least one of the first elastic portion 1200 and the pushing member 300, that is, to simultaneously contact a plurality of second force-bearing contact points 1210. The multi-point contact method can provide better elastic support force. Alternatively, the first contact portion 2110 can be configured to make surface contact with at least one of the first support portion 1100 and the moving contact member 200. The second contact portion 2210 can also be configured to make surface contact with at least one of the first elastic portion 1200 and the pushing member 300. The surface contact method can further provide better elastic support force.

[0116] Furthermore, if the second force-receiving contact 1210 is located on the pusher 300, it can provide better elastic support force. Alternatively, if the second force-receiving contact 1210 is located on the first elastic portion 1200, the closer the second force-receiving contact 1210 is to the pusher 300, the better the elastic support force it can provide. Therefore, in one embodiment, the second contact portion 2210 can be configured to elastically contact at least one second force-receiving contact 1210 of the first elastic portion 1200. In this case, at least one second force-receiving contact 1210 can be directly opposite the pusher 300 in the direction of movement of the moving contact member 200, thereby providing better elastic support force.

[0117] When the elastic structure 100 includes a first elastic element 1000 and a third elastic element 3000, or when the elastic structure 100 includes a first elastic element 1000, a second elastic element 2000, and a third elastic element 3000, the third elastic element 3000 may be configured to elastically contact at least one of the first elastic element 1000 and the movable contact element 200, that is, the third elastic element 3000 elastically contacts either the first elastic element 1000 or the movable contact element 200, or the third elastic element 3000 may simultaneously elastically contact both the first elastic element 1000 and the movable contact element 200.

[0118] Furthermore, when the third elastic element 3000 elastically contacts at least one of the first elastic element 1000 and the movable contact element 200, the third elastic element 3000 can be configured to elastically contact at least one of the first elastic element 1000 and the movable contact element 200 when elastic force is required, or it can be configured to always elastically contact at least one of the first elastic element 1000 and the movable contact element 200. Simultaneously, the third elastic element 3000 can be configured to directly elastically contact at least one of the first elastic element 1000 and the movable contact element 200, or it can be configured to indirectly elastically contact at least one of the first elastic element 1000 and the movable contact element 200 through other structures.

[0119] Since the moving contact 200 reciprocates between the closed position 500 and the open position 600, the third elastic member 3000 can be configured to apply a force suitable for the moving contact 200 to move toward the closed position 500 to at least one of the first elastic member 1000 and the moving contact 200. That is, the force can force the moving contact 200 to move toward the stationary contact 31, ensuring that the moving contact 200 can make stable contact with the stationary contact 31, and has the effect of preventing contact bounce.

[0120] As can be seen from the above, both the second elastic element 2000 and the third elastic element 3000 individually possess the effect of preventing contact point bounce, but their modes of operation are different. The second elastic element 2000 mainly applies an elastic support force between the pushing element 300 and the moving contact element 200. This force can be applied directly between the pushing element 300 and the moving contact element 200, or indirectly between them, for example, indirectly through the first elastic element 1000.

[0121] In contrast, the third elastic element 3000 is not limited to applying an elastic support force between the pushing element 300 and the moving contact element 200. Therefore, whether the moving contact element 200 enters an overtravel state before contacting the stationary contact element 31 or after contact, it can form a more significant elastic force, providing a better elastic force effect. For example, the third elastic element 3000 can use the base 10 or other components in the base 10 as a point of force to exert the energy storage and release elastic force of the third elastic element 3000, thereby acting on at least one of the first elastic element 1000 and the moving contact element 200, forcing the moving contact element 200 to move towards the stationary contact element 31.

[0122] Because the third elastic element 3000 can generate a relatively significant elastic force, whether before or after the moving contact 200 contacts the stationary contact 31 and enters an overtravel state, it provides a better elastic force effect. Therefore, when the moving contact 200 simultaneously has a current-carrying contact 211 and an arc-ignition contact 212, the third elastic element 3000 can also be used to stably achieve the "closing before breaking" of the arc-ignition contact 212, thereby ensuring the stability of the contact resistance of the current-carrying contact 211.

[0123] For example, when the moving contact 200 closes relative to the stationary contact 31, the third elastic element 3000 can ensure that the arcing contact 212 of the moving contact 200 and the stationary contact 32 of the stationary contact 31 close first based on better elastic force. When closing, the arc will concentrate on the first contacting arcing contact 212 and burn. At the same time, the elastic force of the third elastic element 3000 is not applied between the current-carrying contact 211 of the moving contact 200 and the stationary contact 32 of the stationary contact 31. Therefore, when closing, the current-carrying contact 211 of the moving contact 200 and the stationary contact 32 of the stationary contact 31 can close relatively later, avoiding the burning of the current-carrying contact 211.

[0124] Similarly, when the moving contact 200 disconnects relative to the stationary contact 31, the third elastic element 3000 applies an elastic force suitable for keeping the arcing contact 212 of the moving contact 200 and the stationary contact 32 of the stationary contact 31 closed. At this time, the current-carrying contact 211 of the moving contact 200 and the stationary contact 32 of the stationary contact 31 will disconnect first, and the current-carrying contact 211 will not be ablated. The elastic force of the third elastic element 3000 will ensure that the arcing contact 212 of the moving contact 200 and the stationary contact 32 of the stationary contact 31 disconnect later, and the arc will concentrate on the arcing contact 212 that disconnects later and ablate it.

[0125] Therefore, the above technical solution does not simply rely on the gap difference design to ensure that the arcing contact 212 "closes first and then breaks," but rather, based on the gap difference design, it utilizes the elastic force of the third elastic element 3000 to achieve the "closing first and then breaking" of the arcing contact 212. This structural design can more stably achieve the "closing first and then breaking" of the arcing contact 212, thereby ensuring the stability of the contact resistance of the current-carrying contact 211. Of course, those skilled in the art can also, according to design requirements, utilize only the elastic force of the third elastic element 3000 to achieve the "closing first and then breaking" of the arcing contact 212, which is not limited here.

[0126] Regarding the aforementioned third elastic element 3000, in one embodiment, please refer to [reference needed]. Figure 15 and Figure 16 As shown, the third elastic member 3000 may include a connected third support portion 3100 and a third elastic portion 3200. Both the third support portion 3100 and the third elastic portion 3200 are part of the third elastic member 3000, and their positions and dimensions within the third elastic member 3000 are determined by their supporting and elastic functions. Therefore, the third support portion 3100 may be configured to at least elastically contact the first elastic member 1000, and the third elastic portion 3200 may be configured to elastically contact the base 10 of the relay.

[0127] At this time, when the moving contact 200 moves between the open position 600 and the closed position 500, the third elastic member 3000 will deform under force, storing elastic force through elastic contact with the base 10, and enabling the third elastic member 3000 to apply an elastic force toward the first elastic member 1000. The elastic force applied by the third elastic member 3000 to the first elastic member 1000 can be configured to either cause the moving contact 200 to move toward the stationary contact 31 or to cause the moving contact 200 to move away from the stationary contact 31.

[0128] For example, in one embodiment, the movable contact 200 is configured to, when moving in the closed position 500 and the open position 600, allow the third elastic member 3000 to be configured to directly apply a force suitable for movement toward the closed position 500 to the movable contact 200, or indirectly apply a force suitable for movement toward the closed position 500 to the movable contact 200 via the first elastic member 1000. Those skilled in the art can configure this according to actual needs, and no limitation is made herein.

[0129] In one embodiment, the third support portion 3100 may be configured to elastically contact at least one of the first support portion 1100 and the moving contact 200. For example, the third support portion 3100 may elastically contact either the first support portion 1100 or the moving contact 200, or simultaneously elastically contact both. Alternatively, the third support portion 3100 may be fixedly connected to at least one of the first support portion 1100 and the moving contact 200 by means of threads, snap-fit, or the like. Meanwhile, the third elastic portion 3200 is configured to elastically contact the relay base 10 directly or indirectly. For example, the third elastic portion 3200 may be fixedly connected to the relay base 10 directly or indirectly by means of threads, snap-fit, or the like. Alternatively, the third elastic portion 3200 may be movably connected to the relay base 10; for example, the third elastic portion 3200 may be slidably connected to the relay base 10 by means of sliding holes, slide rails, or the like.

[0130] See Figure 22 and Figure 23 As shown, the first elastic element 1000 can be a single independent structure, and only one first support portion 1100 and one first elastic portion 1200 may be provided in the first elastic element 1000. Alternatively, the first elastic element 1000 may be provided with several first support portions 1100 and several first elastic portions 1200. For example, in one embodiment, the first elastic element 1000 may include at least two unit elastic elements, such that the first elastic element 1000 can be divided into two or more unit structures (i.e., unit elastic elements). In this case, each unit elastic element may include connected first support portions 1100 and first elastic portions 1200.

[0131] In some embodiments, at least one unit elastic element may be provided with a second elastic element 2000, or at least one unit elastic element may be provided with a third elastic element 3000. For example, when there are two unit elastic elements, such as... Figure 10 As shown, one unit elastic element can be equipped with a second elastic element 2000, and another unit elastic element can be equipped with a third elastic element 3000. Alternatively, as... Figure 11 As shown, when there are two unit elastic elements, both unit elastic elements can be equipped with a second elastic element 2000. Those skilled in the art can select the structural design of the first elastic element 1000 and the cooperative assembly of the first elastic element 1000 with at least one of the second elastic element 2000 and the third elastic element 3000 according to actual needs, which is not limited here.

[0132] In one embodiment, at least two unit elastic elements include a first unit elastic element 1001 and a second unit elastic element 1002, i.e., there are two unit elastic elements. See also Figure 10As shown, the first contact portion 2110 of the second elastic member 2000 can be configured to elastically contact at least one of the first support portion 1100 and the moving contact member 200 of the first unit elastic member 1001. The second contact portion 2210 of the second elastic member 2000 can be configured to elastically contact at least one of the first elastic portion 1200 and the pushing member 300 of the first unit elastic member 1001, that is, the second elastic member 2000 is provided in the first unit elastic member 1001. Simultaneously, the third support portion 3100 of the third elastic member 3000 is configured to elastically contact at least one of the first support portion 1100 and the moving contact member 200 of the second unit elastic member 1002, that is, the third elastic member 3000 is provided in the second unit elastic member 1002. In this embodiment, the elastic structure 100 includes the first elastic member 1000, the second elastic member 2000, and the third elastic member 3000, and constitutes an elastic combination of the second elastic member 2000 and the third elastic member 3000 relative to the first elastic member 1000.

[0133] Furthermore, the number of moving contacts 200 can be configured to be at least two, with at least one moving contact 200 having a current-carrying contact 211 and at least one moving contact 200 having an arc-ignition contact 212. For example, when the two moving contacts 200 are respectively a first moving contact 200 and a second moving contact 200, the first moving contact 200 has two current-carrying contacts 211, and the second moving contact 200 has two arc-ignition contacts 212. In this case, the first unit elastic member 1001 can be configured to connect to the first moving contact 200, and the second unit elastic member 1002 can be configured to connect to the second moving contact 200.

[0134] In the above embodiments, the second elastic member 2000 is in elastic contact with the first unit elastic member 1001 of the first elastic member 1000, forming an elastic support force between the first moving contact member 200 and the pushing member 300. The elastic support force provided by the second elastic member 2000 compensates for the insufficient support force of the first unit elastic member 1001. Simultaneously, the third elastic member 3000 is in elastic contact with the second unit elastic member 1002 of the first elastic member 1000, forming an elastic support force between the second moving contact member 200 and the pushing member 300. The elastic support force provided by the third elastic member 3000 compensates for the insufficient support force of the second unit elastic member 1002.

[0135] Since the second elastic element 2000 mainly applies elastic support force between the pusher 300 and the first moving contact 200, the elastic support force of the second elastic element 2000 is not obvious before the first moving contact 200 contacts the stationary contact 31. It can only form a more obvious elastic support force after the first moving contact 200 contacts the stationary contact 31 and enters the overtravel state.

[0136] In contrast, the third elastic element 3000 can utilize the base 10 or other components within the base 10 as a point of application, thereby maximizing its energy storage and release of elastic force. Whether before or after the second moving contact 200 contacts the stationary contact 31 and enters an overtravel state, a more significant elastic force can be generated. Therefore, the third elastic element 3000 exhibits a more pronounced elastic force application effect compared to the second elastic element 2000.

[0137] When the first moving contact 200 and the second moving contact 200 are closed relative to the stationary contact 31, the third elastic element 3000 can ensure that the second moving contact 200 and the stationary contact 31 close first based on its superior elastic force. When closing, the electric arc will concentrate on the first contacting arcing contact 212 and burn. Although the second elastic element 2000 can also provide a certain elastic support force to prevent the contact from bouncing back when the first moving contact 200 and the stationary contact 31 are closed, based on the difference in elastic force between the second elastic element 2000 and the third elastic element 3000, it can ensure that the first moving contact 200 and the stationary contact 31 close later (relative to the closing of the second moving contact 200 and the stationary contact 31) when they cooperate. When closing later, the current-carrying contact 211 will not be burned.

[0138] Similarly, when the first moving contact 200 and the second moving contact 200 disconnect relative to the stationary contact 31, the third elastic element 3000 applies an elastic force suitable for keeping the second moving contact 200 and the stationary contact 31 closed. Therefore, the third elastic element 3000 can ensure that the second moving contact 200 and the stationary contact 31 disconnect later based on the better elastic force. When disconnected, the arc will concentrate on the arcing contact 212 that disconnected later and ablate. Also based on the difference in elastic force between the second elastic element 2000 and the third elastic element 3000, when cooperating, the first moving contact 200 and the stationary contact 31 can be allowed to disconnect first (relative to the disconnection of the second moving contact 200 and the stationary contact 31). When disconnected first, the current-carrying contact 211 is not ablated.

[0139] Therefore, the above technical solution does not simply rely on the gap difference design to ensure the arcing contact 212 "closes first and then breaks." Instead, based on the gap difference design, it further utilizes the difference in elastic force between the second elastic element 2000 and the third elastic element 3000, as well as assembly differences, to achieve the "closing first and then breaking" of the arcing contact 212. This structural design can more stably achieve the "closing first and then breaking" of the arcing contact 212, thereby ensuring the stability of the contact resistance of the current-carrying contact 211. Of course, those skilled in the art can also, according to design requirements, utilize only the elastic force of the third elastic element 3000 to achieve the "closing first and then breaking" of the arcing contact 212, which is not limited here.

[0140] 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.

[0141] 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.
