Description

Technical Field

[0001] This invention relates to the field of electronic control device technology, and more specifically, to a relay and its assembly method. 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] A magnetic latching relay is a type of relay that automatically connects and disconnects circuits. The normally closed or normally open state of the main contacts of a magnetic latching relay depends on the action of a permanent magnet. With the expanding applications of relays, magnetic latching relays with auxiliary contact structures have emerged. The auxiliary contacts primarily indicate the contact or open state of the main contacts. However, in related technologies, the assembly of the auxiliary contact structure of magnetic latching relays is difficult, increasing assembly complexity and reducing assembly efficiency.

[0011] According to some embodiments of the present invention, the magnetic rotating component is provided with a first positioning structure, the edge of the main spring is provided with a flange, the flange extends along the length direction of the second through hole, and the flange contacts the first positioning structure.

[0012] According to some embodiments of the present invention, the magnetic rotating component is provided with a second positioning structure, the main body spring is provided with a positioning hole, and the second positioning structure can be limited to the positioning hole.

[0013] According to some embodiments of the present invention, the main body spring includes a main body segment and a contraction segment, one end of the main body segment is connected to the contraction segment, the other end of the main body segment is connected to the contact spring, and the width of the end of the contraction segment connected to the main body segment is greater than the width of the free end of the contraction segment.

[0014] According to some embodiments of the present invention, the contraction section is provided with a buffer hole.

[0015] According to some embodiments of the present invention, the free end of the contraction section is provided with a guide flange, the guide flange is bent in a direction away from the magnetic rotating member, and the angle between the guide flange and the contraction section is an obtuse angle.

[0016] According to some embodiments of the present invention, the auxiliary movable contact is provided with a rib, which can abut against the surface of the limiting portion facing the auxiliary movable contact.

[0017] The relay assembly method provided by the present invention includes:

[0018] A magnetic rotating component and an auxiliary moving contact are provided. The magnetic rotating component is provided with an assembly structure, which includes a connecting section and a limiting part. One end of the connecting section is connected to the magnetic rotating component, and the other end of the connecting section is connected to the limiting part. There is a gap between the limiting part and the magnetic rotating component. The auxiliary moving contact is provided with an assembly hole, which includes a first through hole and a second through hole, and the first through hole communicates with the second through hole.

[0019] The limiting part passes through the first through hole;

[0020] The auxiliary movable contact is moved in a direction away from the first through hole so that the connecting segment can move relative to the auxiliary movable contact to the second through hole, and the auxiliary movable contact is limited between the limiting portion and the magnetic rotating member.

[0021] One embodiment of the above invention has at least the following advantages or beneficial effects:

[0022] (1) In the relay provided in the embodiment of the present invention, during assembly, the limiting part passes through the first through hole, so that the auxiliary moving contact moves into the gap between the magnetic rotating part and the limiting part. At this time, the connecting section also passes through the first through hole. Since the first through hole is connected to the second through hole, the connecting section can move relative to the auxiliary moving contact in a direction away from the first through hole to the second through hole, and limit the auxiliary moving contact between the limiting part and the magnetic rotating part. The assembly process is simple and the assembly efficiency is improved.

[0023] (2) The relay provided in this embodiment of the invention has a first positioning structure for the magnetic rotating component, and a flange is provided on the edge of the main spring plate. The flange extends along the length direction of the second through hole and contacts the first positioning structure. When the limiting part passes through the first through hole, the auxiliary moving contact can be positioned by the flange contacting the first positioning structure. During the movement of the active moving contact in the direction of arrow Z, the flange can maintain contact with the first positioning structure and play a guiding role.

[0024] (3) The relay provided in the embodiment of the present invention has a buffer hole in the shrink section. By providing the buffer hole, it is more conducive to the elastic deformation of the shrink section, which makes it easier to lift up, so that the positioning hole is aligned with the second positioning structure and the second positioning structure enters the positioning hole.

[0025] (4) The relay provided in this embodiment of the invention has a guide flange at the free end of the retractable section. The guide flange bends in the direction away from the magnetic rotating component, and the angle between the guide flange and the retractable section is an obtuse angle. During the process of pushing the auxiliary moving contact in the direction of arrow Z, the guide flange can contact the second positioning structure. As the auxiliary moving contact is pushed further, the retractable section can be tilted up under the guidance of the guide flange, so that the guide flange is located above the second positioning structure. When the auxiliary moving contact moves to the point where the positioning hole is aligned with the second positioning structure, the retractable section can return to its original state, and the second positioning structure is confined within the positioning hole.

Detailed Implementation

[0042] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0043] See Figures 1 to 13 As shown, this embodiment provides a relay, including a magnetic rotating component 100 and an auxiliary moving contact 200. The magnetic rotating component 100 is provided with an assembly structure 110, which includes a connecting section 111 and a limiting part 112. One end of the connecting section 111 is connected to the magnetic rotating component 100, and the other end of the connecting section 111 is connected to the limiting part 112. There is a gap between the limiting part 112 and the magnetic rotating component 100. The auxiliary moving contact 200 is provided with an assembly hole 210, which includes a first through hole 211 and a second through hole 212. The first through hole 211 communicates with the second through hole 212. The limiting part 112 can pass through the first through hole 211, so that the connecting section 111 can move relative to the auxiliary moving contact 200 in a direction away from the first through hole 211 to the second through hole 212, and the auxiliary moving contact 200 is limited between the limiting part 112 and the magnetic rotating component 100.

[0044] In this embodiment, the relay is assembled by passing the limiting part 112 through the first through hole 211, so that the auxiliary moving contact 200 moves into the gap between the magnetic rotating member 100 and the limiting part 112. At this time, the connecting section 111 also passes through the first through hole 211. Since the first through hole 211 is connected to the second through hole 212, the connecting section 111 can move relative to the auxiliary moving contact 200 in a direction away from the first through hole 211 to the second through hole 212, and limit the auxiliary moving contact 200 between the limiting part 112 and the magnetic rotating member 100. The assembly process is simple and the assembly efficiency is improved.

[0045] Specifically, the auxiliary moving contact 200 has a first state (such as...) Figure 7 (as shown) and the second state (as shown) Figure 9 As shown, the state in which the limiting part 112 passes through the first through hole 211, causing the auxiliary movable contact 200 to move into the gap between the magnetic rotating member 100 and the limiting part 112, is defined as the first state of the auxiliary movable contact 200. The state in which the auxiliary movable contact 200 is limited between the limiting part 112 and the magnetic rotating member 100 is defined as the second state. In the first state, the limiting part 112 is located on the side of the auxiliary movable contact 200 away from the magnetic rotating member 100 and opposite to the first through hole 211. At the same time, the connecting section 111 passes through the first through hole 211. Figure 7 , Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown, the auxiliary movable contact 200 is moved along the direction of arrow Z until the connecting section 111 is located in the second through hole 212. This is equivalent to the connecting section 111 moving relative to the auxiliary movable contact 200 in a direction away from the first through hole 211 to the second through hole 212. At this time, the auxiliary movable contact 200 is limited between the limiting part 112 and the magnetic rotating member 100. In other words, by pushing the auxiliary movable contact 200 to the second state in a roughly straight line, the assembly between the auxiliary movable contact 200 and the magnetic rotating member 100 can be achieved, which reduces the assembly difficulty and improves the assembly efficiency.

[0046] It should be understood that the connecting segment 111 can move relative to the auxiliary movable contact 200 in a direction away from the first through hole 211 to the second through hole 212. This can be achieved by either the auxiliary movable contact 200 being stationary and the connecting segment 111 moving, or by the connecting segment 111 being stationary and the auxiliary movable contact 200 moving. For example, during assembly, the magnetic rotating component 100 can be fixed, equivalent to the assembly structure 110 being fixed. By moving the auxiliary movable contact 200, the auxiliary movable contact 200 is mounted on the magnetic rotating component 100.

[0047] In some embodiments, see Figures 1 to 4As shown, the relay also includes a housing 900, a base 300, a coil assembly 400, an active contact 500, a main stationary contact 600, and an auxiliary stationary contact 700. The housing 900 is connected to the base 300. The coil assembly 400, active contact 500, main stationary contact 600, and auxiliary stationary contact 700 are all mounted on the base 300. The active contact is provided with an active contact 501, the main stationary contact is provided with a main stationary contact 601, the auxiliary active contact 200 is provided with an auxiliary active contact 20211, and the auxiliary stationary contact 700 is provided with an auxiliary stationary contact (not shown in the figure).

[0048] The auxiliary stationary contact 700 can be a rigid columnar structure with a circular or rectangular cross-section, and can be made of conductive materials such as metal. The auxiliary stationary contact 700 passes through and is fixed to the base 300. For example, the auxiliary stationary contact 700 can be fixed to the base 300 by any suitable fixing method, such as adhesive dispensing. Utilizing the side of the auxiliary stationary contact 700 to contact the auxiliary moving contact 200 improves the contact reliability between the auxiliary stationary contact 700 and the auxiliary moving contact 200, and facilitates accurate monitoring of the contact state between the active contact 500 and the main stationary contact 600.

[0049] In some embodiments, the auxiliary stationary contact can be considered as being formed by the portion of the auxiliary stationary contact 700 that contacts the auxiliary moving contact 200; that is, the auxiliary stationary contact and the auxiliary stationary contact 700 are an integral structure. Of course, in other embodiments, the auxiliary stationary contact can also be fixedly mounted on the auxiliary stationary contact 700 by means of welding or other methods.

[0050] It should be noted that the auxiliary moving contact 200 and the auxiliary stationary contact 700 can be electrically connected to the positive and negative terminals of the main contact monitoring circuit of the relay, or to the positive and negative terminals of the low-power load circuit, respectively.

[0051] In some embodiments, see Figure 3 , Figure 7 and Figure 8As shown, the magnetic rotating component 100 includes a fixing component 101, a magnet 102, and a first armature 103 and a second armature 104 partially enclosed within the fixing component 101. The magnet 102 is disposed between the first armature 103 and the second armature 104 and is fixed together by the fixing component 101. For example, the fixing component 101 can be an injection-molded part, which encloses the first armature 103, the second armature 104, and the magnet 102 to form a whole. Both ends of the first armature 103 and the second armature 104 are located outside the injection-molded part. The assembly structure 110 can be integrally formed with the fixing component 101. For example, the limiting part 112, the connecting section 111, and the fixing component 101 can be integrally formed by injection molding. A rotating shaft 1011 is provided on the outer surface of the fixing component 101, and a shaft hole is provided on the base 300. The rotating shaft 1011 is installed in the shaft hole and can rotate relative to the base 300 around its own axis to achieve switching between a closed position and an open position. It should be understood that the magnetic rotating element 100 rotates within a certain angular range, rather than rotating 360°. Therefore, the magnetic rotating element 100 oscillates relative to the base 300 about its own axis to achieve switching between the closed and open positions.

[0052] See Figure 3 As shown, the coil assembly 400 includes a coil body 401 and an iron core 402 disposed within the coil body 401. A first yoke 403 and a second yoke 404 are respectively disposed at both ends of the coil body 401. The first yoke 403 is located between one end of the first armature 103 and one end of the second armature 104, and the second yoke 404 is located between the other end of the first armature 103 and the other end of the second armature 104. In the closed position, the active contact 501 contacts the main stationary contact 601, the first armature 103 and the second yoke 404 are attracted together, and the second armature 104 and the first yoke 403 are attracted together. In the open position, the active contact 501 separates from the main stationary contact 601, the first armature 103 and the first yoke 403 are attracted together, and the second armature 104 and the second yoke 404 are attracted together.

[0053] When the current flow direction of the coil body 401 changes, the magnetic rotating component 100 can be driven to rotate relative to the base 300 by the magnetic field force. The swing of the magnetic rotating component 100 relative to the base 300 can cause the active contact to move towards or away from the main stationary contact, so that the active contact 501 and the main stationary contact 601 can contact or separate. The swing of the magnetic rotating component 100 relative to the base 300 can also synchronously cause the auxiliary moving contact 200 to move towards or away from the auxiliary stationary contact 700, so that the auxiliary moving contact 20211 and the auxiliary stationary contact can contact or separate.

[0054] In some embodiments, see Figure 3 and Figure 5As shown, the magnetic rotating component 100 drives the active contact 500 to move closer to the main stationary contact 600, so that the active contact 501 and the main stationary contact 601 come into contact. Simultaneously, it drives the auxiliary moving contact 200 to move closer to the auxiliary stationary contact 700, so that the auxiliary moving contact 20211 and the auxiliary stationary contact come into contact. See also... Figure 4 and Figure 6 As shown, the magnetic rotating component 100 drives the active contact to move away from the main stationary contact, so as to separate the active contact 501 and the main stationary contact 601. At the same time, it drives the auxiliary moving contact 200 to move away from the auxiliary stationary contact 700, so as to separate the auxiliary moving contact 20211 and the auxiliary stationary contact.

[0055] In other embodiments, the magnetic rotating member 100 drives the active contact to move closer to the main stationary contact, so that the active contact 501 and the main stationary contact 601 come into contact. Simultaneously, it drives the auxiliary moving contact 200 to move away from the auxiliary stationary contact 700, so that the auxiliary moving contact 20211 and the auxiliary stationary contact separate. The magnetic rotating member 100 also drives the active contact to move away from the main stationary contact, so that the active contact 501 and the main stationary contact 601 separate. Simultaneously, it drives the auxiliary moving contact 200 to move closer to the auxiliary stationary contact 700, so that the auxiliary moving contact 20211 and the auxiliary stationary contact come into contact.

[0056] See Figure 3 As shown, the active contact 500 and the main stationary contact 600 are mounted on the base 300, with the active contact 500 located between the main stationary contact 600 and the magnetic rotating component 100. The relay also includes a linkage component 800, and the fixing component 101 is connected to the active contact via the linkage component 800. For example, the fixing component 101 is provided with an extension 1012, which can be integrally formed with the fixing component 101. The extension 1012 is fixedly connected to one end of the linkage component 800, and the other end of the linkage component 800 is fixedly connected to the active contact 500.

[0057] For example, when the magnetic rotating member 100 rotates relative to the base 300 to move the extension 1012 toward the main stationary contact, the extension 1012 can drive the active contact to move toward the main stationary contact via the linkage member 800 until the active contact 501 and the main stationary contact 601 come into contact. When the magnetic rotating member 100 rotates relative to the base 300 to move the extension 1012 away from the main stationary contact, the extension 1012 can drive the active contact to move away from the main stationary contact via the linkage member 800 until the active contact 501 and the main stationary contact 601 separate.

[0058] In one embodiment, see Figure 7As shown, the limiting part 112 has a length direction (indicated by the arrow direction X). Along the length direction of the limiting part 112, the size of the first through hole 211 is larger than the size of the second through hole 212, the size of the first through hole 211 is not smaller than the size of the limiting part 112, the size of the second through hole 212 is smaller than the size of the limiting part 112, and the size of the second through hole 212 is not smaller than the size of the connecting section 111. This ensures that the limiting part 112 can directly pass through the first through hole 211 along the arrow direction Y without tilting the auxiliary moving contact 200, facilitating assembly. For example, the size of the first through hole 211 can be slightly larger than the size of the limiting part 112, which reduces the risk of scratches caused by the edge of the first through hole 211 contacting the limiting part 112 during assembly. When the auxiliary movable contact 200 moves in the direction of arrow Z, the connecting portion can enter the second through hole 212, and the limiting portion 112 is located on the side of the auxiliary movable contact 200 away from the magnetic rotating member 100, which acts as a stop for the auxiliary movable contact 200 to prevent it from falling off. For example, the size of the second through hole 212 can be slightly larger than the size of the connecting section 111, which can reduce the risk of scratches caused by the edge of the second through hole 212 contacting the connecting portion during the movement of the auxiliary movable contact 200.

[0059] In one embodiment, see Figure 7 and Figure 9 As shown, both the first through hole 211 and the second through hole 212 have a length direction. The length direction of the first through hole 211 is consistent with the length direction of the limiting part 112, and the length direction of the second through hole 212 is perpendicular to the length direction of the first through hole 211. That is, the length direction of the second through hole 212 is consistent with the arrow direction Z. This makes the assembly hole 210 form a T-shaped hole, which facilitates the processing of the assembly hole 210 and also facilitates the movement of the auxiliary moving contact 200 along the arrow direction Z.

[0060] In one embodiment, see Figure 9 and Figure 13 As shown, the auxiliary moving contact 200 includes a main spring 201 and a contact spring 202. The main spring 201 is connected to the contact spring 202. The mounting hole 210 is provided in the main spring 201. The main spring 201 can be limited between the limiting part 112 and the magnetic rotating member 100.

[0061] In some embodiments, the main spring 201 and the contact spring 202 may be integrally formed. The contact spring 202 extends at least partially from the fixing member 101 to ensure that the fixing member 101 does not interfere with the elastic deformation of the contact spring 202. An auxiliary moving contact 20211 is disposed on the contact spring 202.

[0062] In some embodiments, see Figure 1As shown, there are two auxiliary stationary contacts 700, which are spaced apart. The contact spring 202 is provided with at least one pair of auxiliary moving contacts 20211. In the pair of auxiliary moving contacts 20211, one of the auxiliary moving contacts 20211 contacts one of the auxiliary stationary contacts 700, and the other auxiliary moving contact 20211 contacts the other auxiliary stationary contact 700.

[0063] The contact spring 202 includes at least one branch 2021, as exemplarily seen in [reference needed]. Figure 13 As shown, there are two branches 2021, and each branch 2021 is provided with a pair of auxiliary moving contacts 20211. Specifically, each end of the branch 2021 is provided with an auxiliary moving contact 20211. The auxiliary moving contact 200 and the auxiliary stationary contact 700 adopt a multi-point contact method, which can improve the contact reliability.

[0064] In one embodiment, see Figure 12 and Figure 13 As shown, the magnetic rotating component 100 is provided with a first positioning structure 1013, and the edge of the main spring 201 is provided with a flange 20111. The flange 20111 extends along the length direction of the second through hole 212 and contacts the first positioning structure 1013.

[0065] For example, the first positioning structure 1013 can be a positioning protrusion, which can be integrally formed with the fixing member 101. The positioning protrusion and the assembly structure 110 are disposed on the same surface of the fixing member 101. The shape of the positioning protrusion can be, but is not limited to, a triangle, a circle, a semi-circle, or a rectangle. The main spring 201 has a flange 20111 on its edge extending along the length direction of the second through hole 212. The flange 20111 is located on the side of the main spring 201 away from the fixing member 101. During assembly, after the limiting part 112 passes through the first through hole 211, the auxiliary moving contact 200 can be positioned by contacting the first positioning structure 1013 through the flange 20111. During the movement of the active moving contact in the direction of arrow Z, the flange 20111 can maintain contact with the first positioning structure 1013, playing a guiding role.

[0066] It should be understood that when determining the position of the first positioning structure 1013, the first positioning structure 1013 should be in contact with the flange 20111 as much as possible, but there should be as little interaction force between the two, so as to ensure that the resistance is small during the movement of the auxiliary moving contact 200.

[0067] In one embodiment, see Figure 12 and Figure 13As shown, the magnetic rotating component 100 is provided with a second positioning structure 1014, and the main spring 201 is provided with a positioning hole 20123. The second positioning structure 1014 can be confined within the positioning hole 20123. The second positioning structure 1014 can be a protrusion, and the protrusion can be cylindrical. The cooperation between the second positioning structure 1014 and the positioning hole 20123 helps to improve the positioning accuracy of the auxiliary moving contact 200 in the second state, reduces the risk of displacement of the auxiliary moving contact 200, and helps to improve the contact reliability between the auxiliary moving contact 20211 and the auxiliary stationary contact.

[0068] In one embodiment, see Figure 13 As shown, the main spring 201 includes a main section 2011 and a retractable section 2012. One end of the main section 2011 is connected to the retractable section 2012, and the other end of the main section 2011 is connected to the contact spring 202. The width of the end of the retractable section 2012 connected to the main section 2011 is greater than the width of the free end of the retractable section 2012. This arrangement facilitates elastic deformation of the retractable section 2012, making it easier to lift up, thereby aligning the positioning hole 20123 with the second positioning structure 1014 and allowing the second positioning structure 1014 to enter the positioning hole 20123.

[0069] For example, the main body segment 2011 and the shrinking segment 2012 are integrally formed. The main body segment 2011 is generally rectangular in shape, and the shrinking segment 2012 is generally trapezoidal in shape.

[0070] In one embodiment, see Figure 13 As shown, the contraction section 2012 is provided with a buffer hole 20121. By providing the buffer hole 20121, it is more conducive to the elastic deformation of the contraction section 2012, which makes it easier to lift up, so that the positioning hole 20123 is aligned with the second positioning structure 1014, and the second positioning structure 1014 enters the positioning hole 20123.

[0071] In one embodiment, see 7. Figures 8 to 11 as well as Figure 13As shown, the free end of the contraction section 2012 is provided with a guide flange 20122, which bends away from the magnetic rotating member 100. The angle between the guide flange 20122 and the contraction section 2012 is an obtuse angle. During the process of pushing the auxiliary moving contact member 200 in the direction of arrow Z, the guide flange 20122 can contact the second positioning structure 1014. As the auxiliary moving contact member 200 continues to be pushed, under the guidance of the guide flange 20122, the contraction section 2012 can be tilted up, so that the guide flange 20122 is above the second positioning structure 1014. When the auxiliary moving contact member 200 moves to the positioning hole 20123 and aligns with the second positioning structure 1014, the contraction section 2012 can return to its original shape, and the second positioning structure 1014 is confined within the positioning hole 20123.

[0072] In one embodiment, see Figure 10 and Figure 13 As shown, the auxiliary movable contact 200 is provided with a raised rib 20112, which can abut against the surface of the limiting part 112 facing the auxiliary movable contact 200. By providing the raised rib 20112, the structural strength of the main spring 201 can be increased. At the same time, the abutment between the raised rib 20112 and the limiting part 112 reduces the risk of the auxiliary movable contact wobbling.

[0073] See Figure 14 As shown, this embodiment also provides a relay assembly method, which may include the following steps:

[0074] Step S102: A magnetic rotating component 100 and an auxiliary moving contact 200 are provided. The magnetic rotating component 100 is provided with an assembly structure 110, which includes a connecting section 111 and a limiting part 112. One end of the connecting section 111 is connected to the magnetic rotating component 100, and the other end of the connecting section 111 is connected to the limiting part 112. There is a gap between the limiting part 112 and the magnetic rotating component 100. The auxiliary moving contact 200 is provided with an assembly hole 210, which includes a first through hole 211 and a second through hole 212. The first through hole 211 and the second through hole 212 communicate with each other.

[0075] Step S104: Pass the limiting part 112 through the first through hole 211;

[0076] In step S106, the auxiliary movable contact 200 is moved in a direction away from the first through hole 211 so that the connecting segment 111 can move relative to the auxiliary movable contact 200 to the second through hole 212, and the auxiliary movable contact 200 is limited between the limiting part 112 and the magnetic rotating member 100.

[0077] The relay assembly method provided in this embodiment involves passing the limiting part 112 through the first through hole 211, causing the auxiliary moving contact 200 to move into the gap between the magnetic rotating member 100 and the limiting part 112. At this time, the auxiliary moving contact 200 is in a first state, and the connecting section 111 also passes through the first through hole 211. Since the first through hole 211 is connected to the second through hole 212, the auxiliary moving contact 200 is moved in a direction away from the first through hole 211, so that the connecting section 111 can move relative to the auxiliary moving contact 200 to the second through hole 212, and the auxiliary moving contact 200 is limited between the limiting part 112 and the magnetic rotating member 100. At this time, the auxiliary moving contact 200 is in a second state. The assembly process is simple and improves assembly efficiency. During the assembly process, the auxiliary moving contact 200 can be installed in place simply by moving in the direction of arrow Z, without rotation, reducing the generation of chips.
