Methods, devices, equipment, and storage media for adjusting relay contact pressure

Abstract

This application provides a method, apparatus, device, and storage medium for adjusting the contact pressure of a relay. The moving contact of the relay is disposed on a leaf spring, one end of which is connected to a first part. Rotation of the first part allows the moving contact to move away from or closer to the stationary contact. Before adjustment, based on the target adjustment pressure, a first distance between the moving and stationary contacts is determined when the target adjustment pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact. A first angle is then determined based on this first distance. The first angle indicates the first angle by which the first part needs to rotate to allow the moving contact to move horizontally a first distance without elastic deformation of the leaf spring. Thus, after pre-calculating the first angle, simply controlling the first part to rotate by the first angle in a specific direction is sufficient to bring the moving contact closer to the stationary contact and ensure that the pressure applied by the moving contact to the stationary contact is the target adjustment pressure, thereby saving adjustment time and improving production efficiency.

Description

Technical Field

[0001] This application relates to the field of relay assembly and commissioning, and in particular to a method, apparatus, equipment and storage medium for commissioning relay contact pressure. Background Technology

[0002] A relay connects its internal conductive circuit by bringing its moving and stationary contacts together. To ensure reliable connection of the internal conductive circuit, the contact pressure when the moving and stationary contacts are in contact needs to meet certain requirements. Therefore, during the relay manufacturing process, the contact pressure needs to be adjusted to ensure that the contact pressure when the moving and stationary contacts are in contact meets the requirements.

[0003] When adjusting the contact pressure of a relay, the moving contact can be moved in the direction of the moving contact and applied to the stationary contact by adjusting the moving contact support. During the application of pressure, the adjustment is interrupted multiple times and the contact pressure between the moving and stationary contacts is measured until the contact pressure meets the requirements. In the existing technology, the amount of pressure applied each time is uncontrollable, and multiple trials are often required to achieve successful adjustment, resulting in low production efficiency.

[0016] This application provides a method, apparatus, device, and storage medium for adjusting the contact pressure of a relay. The moving contact of the relay is disposed on a leaf spring, one end of which is connected to a first part. Rotation of the first part allows the moving contact to move away from or closer to the stationary contact. Before adjustment, based on the target adjustment pressure, a first distance between the moving and stationary contacts is determined when the target adjustment pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact. Based on this first distance, a first angle is determined.

[0033] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c alone can mean: a alone, b alone, c alone, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] The terms “center,” “longitudinal,” “lateral,” “up,” “down,” “left,” “right,” “front,” and “rear,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Therefore, they should not be construed as limitations on this application.

[0035] The terms "connected" and "connected" should be interpreted broadly. For example, in circuit structures, "connected" or "connected" can refer not only to physical connections but also to electrical or signal connections. This could be a direct connection (physical connection) or an indirect connection via at least one intermediate component, as long as the circuit is connected. It could also refer to the internal connection between two components. Similarly, a signal connection can refer to a connection via a circuit or a medium, such as radio waves. Those skilled in the art will understand the specific meaning of these terms in this application based on the specific circumstances.

[0036] A relay connects its internal conductive circuit by bringing its moving and stationary contacts together. To ensure reliable connection of the internal conductive circuit, the contact pressure between the moving and stationary contacts needs to meet certain requirements. Therefore, during the relay manufacturing process, the contact pressure needs to be adjusted to ensure that the contact pressure when the moving and stationary contacts come into contact meets the requirements.

[0037] When adjusting the contact pressure of a relay, the moving contact can be moved in the direction of the moving contact and applied to the stationary contact by adjusting the moving contact support. During the application of pressure, the adjustment is interrupted multiple times and the contact pressure between the moving and stationary contacts is measured until the contact pressure meets the requirements. In the existing technology, the amount of pressure applied each time is uncontrollable, and multiple trials are often required to achieve successful adjustment, resulting in low production efficiency.

[0038] This application provides a method for adjusting the contact pressure of a relay, applicable to relays. The method adjusts the contact pressure by rotating a first part to move the moving contact closer to the stationary contact. After pre-calculating the first angle, simply controlling the first part to rotate the first angle in a specific direction is sufficient to move the moving contact closer to the stationary contact and apply the target adjustment pressure. This saves on the adjustment process and improves production efficiency.

[0039] Next, through Figure 1 The structure of a relay is illustrated by example.

[0040] Figure 1 The schematic diagram of the relay provided in this application is as follows: Figure 1 As shown, the relay includes a stationary contact 11, a stationary contact support 12, a moving contact 13, a moving contact support 14, and a leaf spring 15. The stationary contact 11 is disposed on the stationary contact support 12, and the moving contact 13 is disposed on the leaf spring 15. One end of the leaf spring 15 is connected to the moving contact support 14.

[0041] Figure 2 A schematic diagram of the stationary contact support 12 and the stationary contact 11 is shown; Figure 3A schematic diagram of the moving contact support 14 and the moving contact 13 is shown.

[0042] according to Figure 2 As shown, the stationary contact 11 and the stationary contact support 12 can be connected in a fixed manner, such as by soldering the stationary contact 11 onto the stationary contact support 12.

[0043] like Figure 3 As shown, the moving contact 13 and the leaf spring 15 can also be connected in a fixed manner; for example, the moving contact 13 can be welded to the leaf spring 15.

[0044] The moving contact support 14 may specifically include a moving contact support body 141 and a first protrusion, wherein the moving contact support body 141 and the first protrusion are fixedly connected.

[0045] The first protrusion is composed of a first part 22 and a second part 21; the moving contact support body 141 is connected to the second part 21 of the first protrusion; the second part 21 supports plastic deformation. The first part 22 specifically includes a first part body 221 and a second protrusion 222; one end of the leaf spring 15 has a mounting hole for mounting the second protrusion 222; after the second protrusion 222 is riveted and assembled with the mounting hole of the leaf spring 15, one side of the leaf spring 15 contacts the first part body 221.

[0046] This application allows the moving contact to move toward or away from the stationary contact by twisting or rotating the first part to cause plastic deformation in the second part.

[0047] Figure 4 This is a flowchart illustrating the implementation of the relay contact pressure adjustment method provided in this application; for example... Figure 4 As shown, the debugging method provided in this application includes the following steps:

[0048] S401. Determine a first distance based on the target adjustment pressure; wherein the first distance is used to indicate the distance between the moving contact and the stationary contact when the target adjustment pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact to cause elastic deformation of the leaf spring.

[0049] For example, the magnitude of the target adjustment pressure is α Newtons, and the first distance is used to indicate the distance between the moving contact and the stationary contact after applying a force of α Newtons to the moving contact on the leaf spring in a direction away from the stationary contact.

[0050] This application does not limit the shapes of the moving contact, stationary contact, leaf spring, and the first part of the body. The shapes of the moving contact and stationary contact can be cuboid, hemispherical, or similar. Figure 2 and Figure 3 The semi-cylindrical shape shown is an example.

[0051] The leaf spring can be a cuboid with a very small thickness; the shape of the first part of the body can also be a cuboid.

[0052] This application uses the example of a stationary contact being a cuboid, a moving contact being a hemispherical shape, a leaf spring being a very thin cuboid, and the first part of the body being a cuboid to illustrate how to adjust the relay contact pressure. The following will explain... Figure 5 and Figure 6 This diagram illustrates the positional relationship between the moving and stationary contacts before and after applying the target adjustment pressure to the moving contact on the leaf spring along a direction away from the stationary contact.

[0053] Figure 5 A schematic diagram showing the positional relationship between the moving and stationary contacts before the target adjustment pressure is applied to the moving contact on the leaf spring, i.e., when the leaf spring is in an unloaded state.

[0054] like Figure 5 As shown, the inner surface of the stationary contact is fixedly connected to the stationary contact support, and the bottom surface of the moving contact is fixedly connected to the leaf spring. When the leaf spring is not under stress, the inner surface of the stationary contact is parallel to the bottom surface of the moving contact.

[0055] exist Figure 5 In this diagram, the radius of the moving contact is R; the distance between the plane containing the upper surface of the first part and the center of the moving contact is L0; the theoretical design distance between the moving contact and the stationary contact is called the first theoretical design distance, denoted as S; the distance between the upper surface of the first part and the center of the first part is e; the thickness of the leaf spring is h; the distance between the inner surface of the first part that contacts the leaf spring and the center of the first part is a; and the distance between the center of the first part and the plane containing the outer surface of the stationary contact is d. The center of the first part is denoted as O.

[0056] Before manufacturing a relay, the distance between the moving contact and the stationary contact is designed as the first theoretical design distance S. The manufacturer produces the relay based on the first theoretical design distance S. The actual distance between the moving contact and the stationary contact of the relay to be tested is recorded as S0.

[0057] In the absence of manufacturing errors, S0 is the same as S; in the presence of manufacturing errors, S0 may deviate slightly from S.

[0058] The distance between the upper surface of the first part and the center of the first part, the thickness of the leaf spring, the distance between the inner surface of the first part that contacts the leaf spring and the center of the first part, and the distance between the center of the first part and the plane containing the outer surface of the stationary contact can be obtained using the corresponding theoretically designed distances, or by actual measurement.

[0059] In some embodiments, the center of the first portion is the center of the first portion body. The upper surface of the first portion is the upper surface of the first portion body. The center of the moving contact is the center of the bottom surface of the moving contact.

[0060] The upper surface of the first part is the same as the upper surface of the first part body. The actual distance between the moving contact and the stationary contact is the shortest actual distance between the outer surfaces of the moving contact and the stationary contact. The distance between the upper surface of the first part and the center of the first part is half the height of the first part; the distance between the inner surface of the first part that contacts the leaf spring and the center of the first part is half the width of the first part. The outer surface of the moving contact is a hemispherical spherical surface.

[0061] Figure 6 The diagram shows the positional relationship between the stationary and moving contacts after a target adjustment pressure is applied to the moving contact in a direction away from the stationary contact.

[0062] from Figure 6 It can be seen that after applying the target adjustment pressure to the moving contact in a direction away from the stationary contact, the moving contact moves in a direction away from the stationary contact, and the leaf spring undergoes elastic deformation.

[0063] In this embodiment, after applying the target adjustment pressure to the moving contact along the direction away from the stationary contact, the position of the moving contact is the first position, and the distance between the first position and the first plane (denoted as the second distance) is L; in some embodiments, the first position indicates the center position of the moving contact. The first plane is the plane containing the upper surface of the first part.

[0064] In this application, the first distance specifically refers to the sum of the actual distance S0 between the moving contact and the stationary contact when the leaf spring is in an unloaded state (i.e., the actual distance S0 between the outer surface of the moving contact and the outer surface of the stationary contact) and the actual horizontal elastic deformation F0 that occurs at a point on the leaf spring connected to the center of the moving contact when the target adjustment pressure is applied to the moving contact at a position away from the stationary contact. In other words, the first distance is S0 + F0.

[0065] After applying a target adjustment pressure to the moving contact on the leaf spring in a direction away from the stationary contact, causing the leaf spring to elastically deform, the center position of the moving contact is the first position. When no pressure is applied to the moving contact (the leaf spring does not deform), the center position of the moving contact is the second position. When the first part is controlled to rotate along the first direction until the moving contact contacts the stationary contact (the leaf spring does not deform during this process), the center position of the moving contact is the third position.

[0066] So, if Figure 6 As shown, the distance between the first position and the second position is equal to F, and the distance between the second position and the third position is equal to S.

[0067] S402. Determine the first angle based on the first distance, the second distance from the first position to the first plane, and the third distance.

[0068] As described above, the first position is the position of the moving contact after applying the target adjustment pressure to the moving contact along a direction away from the stationary contact; the first plane is the plane containing the upper surface of the first part; the second distance is... Figure 6 L in the equation. The third distance is the distance between the upper surface of the first part and the center of the first part.

[0069] It is understandable that if the first part rotates in the first direction, the moving contact may come into contact with the stationary contact, thereby applying pressure to the stationary contact and causing the leaf spring to deform. When calculating the first angle, this deformation needs to be converted into an angle as well.

[0070] Therefore, the first angle is: in the absence of a stationary contact and its support, when controlling the first part to rotate along a first direction to drive the leaf spring to rotate, causing the moving contact on the leaf spring to move a first distance, the angle by which the first part needs to rotate. When the first part rotates along the first direction, the moving contact moves along the direction closer to the stationary contact.

[0071] In the absence of a stationary contact and its support, the leaf spring will not come into contact with any object during rotation, and the leaf spring will not deform.

[0072] The first angle is also equal to the sum of the angle that the first part needs to rotate when the moving contact moves from the second position to the first position, and the angle that the first part needs to rotate when the moving contact moves from the second position to the third position.

[0073] The formula for calculating the first angle is shown in Formula 1:

[0074]

[0075] Where θ is the first angle; the first distance is S0+F0, L is the distance between the first position and the upper surface of the first part, which can be calculated through the following embodiment; e is the third distance.

[0076] The third distance is the same as the length of the surface in contact with the leaf spring in the first part; for example... Figure 3 As shown, the surface of the first part that contacts the leaf spring is rectangular in shape, and the third distance e is the same as half the length of the rectangle.

[0077] S403. Control the first part to rotate a first angle along the first direction, so as to adjust the pressure by setting the pressure applied by the moving contact to the stationary contact as the target.

[0078] Before S403 is executed, the leaf spring is in an unstressed state, that is, the leaf spring is not under pressure and does not undergo elastic deformation in this state.

[0079] Figure 6 A side view of the stationary contact, moving contact, leaf spring, and first part of the relay is shown.

[0080] In this application, the first part can be controlled to rotate clockwise or counterclockwise, thereby causing the leaf spring to rotate clockwise or counterclockwise, so that the moving contact on the leaf spring moves away from or towards the stationary contact.

[0081] In this application, the first direction can be the rotation direction of the first part when the moving contact on the leaf spring approaches the stationary contact; for example, such as... Figure 4 As shown, when the first part rotates counterclockwise, the moving contact on the leaf spring moves closer to the stationary contact. When the first part rotates clockwise, the moving contact on the leaf spring moves away from the stationary contact. Therefore, in Figure 4 In the scenario shown, the first direction can be counterclockwise.

[0082] In some embodiments, the execution subject of the relay contact pressure debugging method of this application can be an electronic device with control capability. The electronic device is connected to the first part. After calculating the first angle, the electronic device controls the first part to rotate the first part around the center of the first part as the rotation center and along the first direction by the first angle.

[0083] Next, the process of rotating the first part of S403 by the first angle will be explained.

[0084] When the first part begins to rotate in the first direction, it drives the leaf spring to rotate in the same direction, causing the moving contact to move closer to the stationary contact. Before the moving contact contacts the stationary contact, the leaf spring does not deform. When the first part rotates to the point where the moving contact contacts the stationary contact, the rotation angle has not yet reached the first angle. Therefore, the first part continues to rotate. At this point, the moving contact begins to apply pressure to the stationary contact, and the leaf spring deforms. When the first part rotates to the first angle and then stops rotating, the magnitude of the pressure applied by the moving contact to the stationary contact is the target adjustment pressure.

[0085] The following explains in detail why rotating the center of the first part by θ along the first direction can make the contact pressure between the moving and stationary contacts the same as the target adjustment pressure. The contact pressure between the moving and stationary contacts can also be described as the pressure exerted by the moving contact on the stationary contact, or the pressure exerted by the stationary contact on the moving contact.

[0086] It is understandable that the deformation of the leaf spring is basically the same when the target adjustment pressure is applied to the moving contact in the direction away from the stationary contact, and when the target adjustment pressure is applied to the center point of the moving contact on the leaf spring in the direction closer to the stationary contact.

[0087] Therefore, if the leaf spring is in an unloaded state and the first part is controlled to rotate along the first direction, when the moving contact just contacts the stationary contact, the moving contact has not yet applied pressure to the stationary contact, nor has it received a reaction force from the stationary contact. At this time, the distance the moving contact moves is the same as S0. If the first part is controlled to continue rotating along the first direction, the moving contact applies pressure to the stationary contact, and the moving contact receives a reaction force from the stationary contact, causing the leaf spring to deform. When the first part rotates along the first direction by an angle θ, the deformation of the leaf spring reaches F0.

[0088] Since the deformation of the leaf spring is F0 when the target adjustment pressure is applied to the moving contact in a direction away from the stationary contact, if the deformation of the leaf spring is F0 when the moving contact applies pressure to the stationary contact, then the pressure applied by the moving contact to the stationary contact is the target adjustment pressure. In this way, the adjustment of the relay contact pressure is achieved.

[0089] The following explains how Formula 1 was derived.

[0090] As described above, the first angle is also equal to the sum of the angle by which the first part needs to rotate when the moving contact moves from the second position to the first position, and the angle by which the first part needs to rotate when the moving contact moves from the second position to the third position.

[0091] Figure 7 This is a schematic diagram showing the positional relationship between the moving contact and the stationary contact after applying a target adjustment pressure along a direction away from the stationary contact, as provided in an embodiment of this application.

[0092] like Figure 7 As shown, connecting the third position to the center of the first part, and connecting the first position to the center of the first part, forms a sector with the first position, the third position, and the center of the first part. The distance between the first position and the center of the first part is Ra, and the moving contact is hemispherical with a radius of R.

[0093] Ideally, if the leaf spring is controlled to produce a lateral elastic deformation F, then the leaf spring is in an unloaded state, and the center of the first part needs to be twisted by the same angle as the first angle θ, as shown in Formula 2:

[0094]

[0095] Where La is the arc length corresponding to θ. For example... Figure 7As shown, L is the distance between the first position and the upper surface of the first part; e is the third distance; S0+F0 is the first distance; R is the radius of the moving contact; and d is the distance between the center of the first part and the plane containing the outer surface of the stationary contact.

[0096] In this embodiment, the first angle is less than 14°. In this case, La=Ra*θ≈S+F.

[0097] The relay designed in this application embodiment guarantees L+e >> S+F+Rd. Based on this, Formula 2 can be transformed into Formula 1.

[0098] Figure 8 The diagram shows the positional relationship between the stationary contact and the moving contact after rotating a first angle along a first direction with the center of the first part as the center of rotation and the leaf spring in an unloaded state.

[0099] After the moving contact applies the target adjustment pressure to the stationary contact, ideally, the direction of the target adjustment pressure P applied by the moving contact to the stationary contact deviates to a certain extent from the direction of the target adjustment pressure T applied by the moving and stationary contacts in reality. The two directions satisfy Formula 3:

[0100]

[0101] Where Ls is the vertical distance between the lowest point of the upper surface of the first part after rotation and the third position.

[0102] In this application, suitable F and L can be selected such that Ls is approximately equal to L, thus making T and P approximately equal.

[0103] In summary, as long as the first part is twisted along the first direction by the first angle, the pressure applied by the moving contact to the stationary contact is the target adjustment pressure.

[0104] This application provides a method for adjusting the contact pressure of a relay. The moving contact of the relay is mounted on a leaf spring, and one end of the leaf spring is connected to a first part supporting the moving contact. Rotation of the first part moves the moving contact closer to or further away from the stationary contact. Before adjusting the contact pressure, a first distance between the moving and stationary contacts is determined based on the target adjustment pressure. This distance is calculated when the target adjustment pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact, causing deformation of the leaf spring. A first angle is then determined based on this first distance. The first angle indicates the first angle by which the first part needs to rotate to allow the moving contact to move horizontally a first distance without elastic deformation of the leaf spring. Thus, after pre-calculating the first angle, simply controlling the first part to rotate by the first angle in a specific direction allows the moving contact to move closer to the stationary contact, ensuring that the pressure applied by the moving contact to the stationary contact is the target adjustment pressure. In existing technologies, when adjusting the contact pressure of a relay, the adjustment process is repeatedly interrupted to measure the contact pressure between the moving and stationary contacts until the contact pressure meets the requirements. In these technologies, the magnitude of the applied pressure is uncontrollable each time, often requiring multiple trials to achieve successful adjustment, resulting in low production efficiency. Therefore, this application, compared to existing technologies, saves on the adjustment process and improves production efficiency.

[0105] Next, through Figure 9 The specific implementation details the process of determining the first distance.

[0106] This application provides a method for adjusting contact pressure, in which a first distance can be determined by calculating the deformation of the leaf spring. Figure 9 The flowchart for implementing the relay contact pressure adjustment method provided in the embodiments of this application is as follows: Figure 9 As shown, S401 can be achieved through the following steps:

[0107] S4011. Based on the target adjustment pressure, the second distance, the elastic modulus of the leaf spring, the thickness of the leaf spring, and the width of the leaf spring, determine the first horizontal elastic deformation of the leaf spring when the target adjustment pressure is applied to the moving contact in a direction away from the stationary contact.

[0108] The second distance is the shortest distance between the first position and the plane containing the upper surface of the first part.

[0109] The formula for calculating the first horizontal elastic deformation of the leaf spring in S4011 is shown in Formula 4:

[0110]

[0111] Wherein, F is the first horizontal elastic deformation, specifically the first horizontal elastic deformation at the center of the moving contact on the leaf spring, which is calculated according to Formula 4. In an ideal situation, the first elastic deformation F is the same as the actual elastic deformation F0 of the leaf spring.

[0112] P is the target adjustment pressure; L is the distance between the first position and the upper surface of the first part; b is the width of the leaf spring; E is the elastic modulus of the leaf spring; h is the thickness of the leaf spring. P is preset according to actual needs, E can be determined according to the material of the leaf spring, b and h can be the corresponding theoretical design distances, or they can be obtained by measurement; L can be calculated through the following embodiment, which will not be elaborated here.

[0113] Specifically, the first horizontal elastic deformation of the leaf spring is the first horizontal elastic deformation at the location of the center of the moving contact on the leaf spring.

[0114] S4012. Determine the first distance based on the first horizontal elastic deformation of the leaf spring.

[0115] As mentioned above, the first distance is the sum of the actual distance S0 between the stationary and moving contacts and the actual horizontal elastic deformation F0 when the leaf spring is in an unloaded state, S0+F0. In this application, S0+F0 can be obtained by separately determining S0 and F0 and then adding them together; or, S0+F0 can be directly calculated using the corresponding formula. Both methods require first calculating the first horizontal elastic deformation of the leaf spring.

[0116] Next, through Figure 10 The example illustrates how to calculate the first horizontal elastic deformation of a leaf spring by separately determining S0 and separately determining F0.

[0117] Figure 10 This is a flowchart illustrating the implementation of the relay contact pressure measurement method provided in this application embodiment. Figure 10 As shown, S4012 can be implemented through the following steps:

[0118] Sa1. Based on the first horizontal elastic deformation of the leaf spring and the first theoretical design distance between the moving contact and the stationary contact when the leaf spring is in an unloaded state, determine the first distance.

[0119] As mentioned above, in the absence of manufacturing errors or when the manufacturing errors are negligible, the actual distance S0 between the moving contact and the stationary contact measured when the leaf spring is in an unloaded state is the same as the theoretical design distance S between the moving contact and the stationary contact when the leaf spring is in an unloaded state. Therefore, the theoretical design distance S between the moving contact and the stationary contact can be taken as the actual distance S0 between the moving contact and the stationary contact.

[0120] In this application, when the target adjustment pressure is applied to the moving contact, the error between the actual horizontal elastic deformation F0 at the center position of the moving contact on the leaf spring and the calculated first elastic deformation F is negligible. Therefore, the first elastic deformation F can be determined as F0.

[0121] In this case, the sum of the first horizontal elastic deformation and the first theoretical distance can be determined as the first distance. Thus, with minimal manufacturing error, the first angle can be quickly calculated, allowing for rapid adjustment of the relay contact pressure.

[0122] Next, through Figure 11 The example illustrates how to directly solve S0+F0 using the corresponding formula.

[0123] Figure 11 This is a flowchart illustrating the implementation of the relay contact pressure adjustment method provided in this application embodiment. Figure 11 As shown, S4012 can be implemented through the following steps:

[0124] Sa2, based on the first level elastic deformation, determine at least one distance set, the distance set including the fourth distance and the fifth distance.

[0125] Figure 12 A schematic diagram showing the relationship between the fourth distance, the fifth distance, and S+F is presented.

[0126] Where S0 is the actual distance between the moving contact and the stationary contact, F1 is the fourth distance, and F2 is the fifth distance.

[0127] Among them, the fourth distance is less than S+F; the fifth distance is greater than S+F.

[0128] The values ​​of the fourth and fifth distances are taken near the first level of elastic deformation, which makes the stiffness of the leaf spring more accurate.

[0129] Sa3. For each distance set, determine the first pressure and the second pressure.

[0130] The first pressure is the pressure that needs to be applied to the moving contact when it moves away from the stationary contact until the distance between the moving contact and the stationary contact reaches the fourth distance.

[0131] The second pressure is the pressure that needs to be applied to the moving contact to move it away from the stationary contact until the distance between the moving contact and the stationary contact reaches the fifth distance.

[0132] For each distance set, Sa3 to Sa6 must be executed to obtain the sixth distance corresponding to each distance set.

[0133] Both the first and second pressures were measured.

[0134] The movement of the moving contact in a direction away from the stationary contact is achieved by applying pressure to the moving contact in the same direction.

[0135] When there are multiple distance sets, each distance set corresponds to a first pressure and a second pressure.

[0136] Sa4. Based on the first pressure, the second pressure, the fourth distance, and the fifth distance, determine the first stiffness of the leaf spring.

[0137] The first stiffness of the leaf spring can be determined by formula five.

[0138]

[0139] Wherein, P2 is the second pressure, P1 is the first pressure; F2 is the fifth distance, and F1 is the fourth distance.

[0140] When there are multiple distance sets, a first stiffness can be calculated for each distance set.

[0141] Sa5. Based on the first stiffness of the leaf spring, the first pressure, the target adjustment pressure, and the fourth distance, determine the sixth distance corresponding to the distance set.

[0142]

[0143] Where F3 is the sixth distance, P is the target adjustment pressure, P1 is the first pressure, K is the first stiffness of the leaf spring, and F1 is the fourth distance.

[0144] Sa6. Determine the first distance based on the sixth distance corresponding to the entire distance set.

[0145] When the number of distance sets is one, the sixth distance is equal to the first distance. That is, S0 + F0 = F3.

[0146] When there are multiple distance sets, the sixth distance corresponding to all distance sets is selected to obtain at least one sixth distance that meets the preset conditions.

[0147] Specifically, the average value of the sixth distances corresponding to all distances is calculated, and the sixth distances that differ from the average value by more than a preset threshold are removed to obtain the at least one sixth distance. Then, the first distance is determined based on the average value of the at least one sixth distance.

[0148] In this embodiment, if there are manufacturing errors or errors in the elastic deformation of the leaf spring, the first theoretical design distance S will have a certain error compared to S0, and F will have an error compared to F0. Therefore, S cannot be determined as S0, and F cannot be determined as F0, so the first distance S0+F0 cannot be determined based on S+F. The stiffness of the leaf spring can be measured first to determine a more accurate first distance based on the stiffness of the leaf spring.

[0149] As described above, the second distance L between the first position and the plane containing the first part was used when calculating the elastic deformation of the leaf spring; next, through Figure 13 The embodiments illustrate how the second distance L is determined.

[0150] Figure 13 A flowchart illustrating the implementation of the relay contact pressure adjustment method provided in this application embodiment; as follows: Figure 13 As shown, prior to S402, the method further includes:

[0151] S402a. Based on the position information of the leaf spring in an unloaded state, the target adjustment pressure, the second distance, the elastic modulus of the leaf spring, the thickness of the leaf spring, the width of the leaf spring, and the second elastic deformation of the leaf spring when the target adjustment pressure is applied to the moving contact in a direction away from the stationary contact, a deflection curve equation is constructed.

[0152] The constructed deflection curve equation is shown in Formula 7:

[0153]

[0154] Where x is the position information of the leaf spring in an unloaded state, and x can be the position information of any point on the leaf spring; this position information is used to represent the distance of the point from the upper surface of the first part; F(x) is the second elastic deformation of the leaf spring; P is the target adjustment pressure; L is the second distance; E is the elastic modulus of the leaf spring; b is the width of the leaf spring; and h is the thickness of the leaf spring.

[0155] S402b. Based on the deflection curve equation and the seventh distance, determine the second distance.

[0156] The seventh distance is the distance between the moving contact and the upper surface of the first part when the leaf spring is in an unloaded state. That is, the shortest distance between the second position and the upper surface of the first part.

[0157] In some embodiments, the deflection curve equation is first differentiated to obtain Formula 8 as follows:

[0158]

[0159] Where G(x) is the derivative of the second elastic deformation of the leaf spring. Its distance from the seventh distance and the second distance satisfy the following formula:

[0160]

[0161] L0 is the seventh distance, which is the distance between the center of the moving contact and the surface of the first part when the leaf spring is not under force. This distance can be the corresponding theoretical design distance or it can be obtained by measurement.

[0162] Then, by solving Formula 9, the second distance L can be obtained.

[0163] In this application, the first pressure and the second pressure can be measured by a force-displacement sensor. The force-displacement sensor has a test rod that can push an object to move along the test direction. During the process of pushing the object to move along the test direction, the detection element of the force-displacement sensor can measure the reaction force of the object on the test rod.

[0164] Next, through Figure 14 The example illustrates how to measure the first and second pressures using a force-displacement sensor.

[0165] This application provides a method for adjusting the pressure of relay contacts. Figure 14 A flowchart illustrating the implementation of the relay contact pressure adjustment method provided in this application embodiment; as follows: Figure 14 As shown, Sa3 can be implemented in the following ways:

[0166] Sa31. Send a first command to the force displacement sensor. The first command is used to instruct the force displacement sensor to control the test rod to push the moving contact to move away from the stationary contact until the distance between the moving contact and the stationary contact is the fourth distance.

[0167] During testing, the test rod of the force displacement sensor approaches the moving contact along the direction away from the stationary contact. Upon contact with the moving contact, it pushes the moving contact away from the stationary contact, causing the leaf spring to deform. When the test rod pushes the moving contact to a distance of the fourth distance between the moving and stationary contacts, the force displacement sensor stops pushing the moving contact. At this point, the force displacement sensor measures the first reaction force exerted by the moving contact on the test rod, which is the same as the first pressure.

[0168] Sa32 receives the first response data sent by the force displacement sensor based on the first command.

[0169] The first response data is the first reaction force experienced by the test rod when it pushes the moving contact to move away from the stationary contact in a direction away from the stationary contact until the distance between the moving contact and the stationary contact is the fourth distance.

[0170] Sa33, send a second command to the force displacement sensor. The second command is used to instruct the force displacement sensor to control the test rod to continue pushing the moving contact in a direction away from the stationary contact until the distance between the moving contact and the stationary contact is the fifth distance.

[0171] Sa33 continues to push the moving contact based on Sa31. The force displacement sensor controls the test rod to continue pushing the moving contact away from the stationary contact until the distance between the moving contact and the stationary contact is the fifth distance. At this time, the force displacement sensor stops pushing the moving contact. At this time, the force displacement sensor measures the second reaction force acting on the force displacement sensor test rod by the moving contact. This second reaction force is the same as the second pressure.

[0172] Sa34 receives the second response data sent by the force displacement sensor based on the second command.

[0173] The second response data is the second reaction force experienced by the test rod when the test rod continues to push the moving contact away from the stationary contact until the distance between the moving contact and the stationary contact is a fifth distance.

[0174] The second reaction force is the same as the second pressure.

[0175] In this embodiment, during the adjustment of the relay contact pressure, it is only necessary to control the force displacement sensor to push the moving contact to move once in a direction away from the stationary contact to obtain the first pressure and the second pressure. Based on the first and second pressures, a first stiffness is determined, a first distance is determined based on the first stiffness, and a first angle is determined based on the first distance. The relay contact pressure is then adjusted according to the first angle. This improves the efficiency of relay production.
