Abstract
Description
Technical Field
[0001] This application relates to the field of relay technology, and in particular to a coil and auxiliary contact lead-out assembly and a relay. Background Technology
[0002] A relay is a widely used electrical control device, applied in household appliances, automobiles, industrial control, power systems, communication devices, and other fields. High-voltage DC relays are a type of relay. Some high-voltage DC relays have auxiliary contacts. These relays include a relay body and lead-out components. The relay body includes a coil assembly, active contacts, main stationary contacts, and auxiliary contact assemblies. The auxiliary contact assembly monitors the closed or open state of the active and main stationary contacts. The lead-out components include auxiliary lead-out terminals and coil lead-out terminals. The auxiliary lead-out terminals connect with the auxiliary stationary contacts in the auxiliary contact assembly, and the coil lead-out terminals connect with the coil assembly.
[0003] In related technologies, the fitting accuracy between the auxiliary stationary contact and the auxiliary lead-out terminal, between the coil lead-out terminal and the coil assembly, and between the auxiliary lead-out terminal and the coil lead-out terminal is poor, which makes assembly difficult when assembling the relay. Utility Model Content
[0004] Therefore, it is necessary to provide a coil and auxiliary contact lead-out assembly and a relay to address the above problems. The lead-out assembly is easy to assemble onto the relay body, which is beneficial for relay assembly.
[0005] On the one hand, a lead-out assembly for the coil and auxiliary contacts is provided.
[0006] include:
[0007] The first component includes a first insulating member, an auxiliary lead-out terminal connected to one end of the first insulating member, and a first conductive portion connected to the other end of the first insulating member. The first conductive portion is electrically connected to the auxiliary lead-out terminal, and the auxiliary lead-out terminal is used to connect to an auxiliary terminal of a relay.
[0008] The second component includes a second insulating member and coil lead terminals, a second conductive portion, an auxiliary pin, and a coil pin, all disposed on the second insulating member. The coil lead terminals are used to connect to the coil assembly of the relay. The coil pins are electrically connected to the coil lead terminals. The auxiliary pins are electrically connected to the second conductive portion. The second conductive portion is used to connect to the first conductive portion.
[0009] In one embodiment, the second conductive portion is in contact with the first conductive portion.
[0010] In one embodiment, one of the first conductive portion and the second conductive portion is inserted into the other.
[0011] In one embodiment, at least a portion of the first conductive portion protrudes beyond the exterior of the first insulating member;
[0012] Alternatively, at least a portion of the second conductive portion protrudes outside the second insulating member.
[0013] In one embodiment, the first insulating member and the second insulating member are detachably connected.
[0014] In one embodiment, one of the first insulating member and the second insulating member is provided with a first insertion protrusion, and the other is provided with a first insertion hole, wherein the first insertion protrusion is fitted into the first insertion hole.
[0015] In one embodiment, the first insulating member includes a first part and a second part, the second part being connected to the first part and forming an angle with the first part, the first conductive part and the first plug-in protrusion being disposed at the end of the first part away from the second part, and the auxiliary lead-out terminal being disposed at the end of the second part away from the first part.
[0016] In one embodiment, a reinforcing portion is provided at the end of the first split body away from the second split body, the reinforcing portion protruding from one side of the first split body in the thickness direction, and the first conductive portion is disposed on the reinforcing portion.
[0017] In one embodiment, the first component and the second component are an integral structure, and the connection between the first component and the second component is provided with reinforcing ribs.
[0018] In one embodiment, the auxiliary lead-out terminal is connected to the first conductive part via a conductive sheet, and the auxiliary lead-out terminal, the conductive sheet, and the first conductive part are an integral structure.
[0019] In one embodiment, the second conductive part and the auxiliary pin are an integral structure, and / or the coil lead terminal and the coil pin are an integral structure.
[0020] In one embodiment, the auxiliary lead-out terminal, the first conductive part, and the conductive sheet are all integrally formed on the first insulating member;
[0021] And / or, the coil lead-out terminal, the second conductive part, the auxiliary pin, and the coil pin are all integrally formed on the second insulating member.
[0022] In one embodiment, when both the auxiliary pin and the coil pin are integrally formed on the second insulating member, the auxiliary pin and the coil pin are spaced apart along the same direction.
[0023] In one embodiment, the second insulating member is provided with a second insertion protrusion for insertion into the circuit board of the coil assembly.
[0024] On the other hand, a relay is also provided, including an auxiliary terminal, a coil assembly, and a lead-out assembly for the coil and auxiliary contacts described above. The auxiliary lead-out terminal in the lead-out assembly is connected to the auxiliary terminal, the coil lead-out terminal in the lead-out assembly is connected to the coil lead-out terminal of the coil assembly, and the second conductive part in the lead-out assembly is electrically connected to the first conductive part.
[0025] In one embodiment, the coil assembly further includes a coil component and a circuit board electrically connected to the coil component, the coil component being disposed on one side of the lead-out assembly, the circuit board being disposed between the coil component and the lead-out assembly, and the coil lead-out terminals being plugged into the circuit board.
[0026] In one embodiment, the device further includes a housing, the auxiliary terminal being an auxiliary stationary contact, the auxiliary stationary contact, the coil component, the circuit board, the first insulating member, and the second insulating member being disposed inside the housing, the housing being provided with a connector, and the end of the auxiliary pin away from the second insulating member and the end of the coil pin away from the second insulating member being disposed in the connector.
[0027] In one embodiment, the auxiliary stationary contact, the auxiliary lead-out terminal, the first conductive part, the second conductive part, the auxiliary pin, the coil lead-out terminal, and the coil pin are each provided in at least two forms.
[0028] The aforementioned coil and auxiliary contact lead-out assembly, with its auxiliary lead-out terminals located in the first assembly, auxiliary coil lead-out terminals located in the second assembly, and a second conductive part for electrical connection with the first conductive part, allows for separate assembly of the first and second assemblies with the relay body during assembly. This minimizes the mutual influence between the first and second assemblies, improving the fitting accuracy between auxiliary terminals, between coil lead-out terminals and coil assemblies, and between auxiliary lead-out terminals and coil lead-out terminals. It also facilitates the proper connection of auxiliary lead-out terminals and the connection of auxiliary coil lead-out terminals to the coil assemblies. Furthermore, the second conductive part for electrical connection with the first conductive part allows for the assembly of the first and second assemblies together with the relay body, thus reducing the precision requirements for the lead-out assembly. Additionally, the auxiliary lead-out terminals and auxiliary pins can be added separately during manufacturing, reducing the manufacturing difficulty of the lead-out assembly. Furthermore, when the assembly directions of the auxiliary leads and the coil leads and the coil assembly are inconsistent, the first and second components can be connected to the relay body separately when assembling the lead assembly, avoiding interference between them and reducing assembly difficulty, thus facilitating relay assembly. Additionally, placing both the auxiliary pins and the coil pins on the second insulating component improves their mating accuracy and prevents metal shavings from rubbing against the conductive parts of the external connector during mating, thereby reducing the risk of adjacent pins becoming conductive due to scraping.
[0029] Furthermore, the first insulating component and the second insulating component are detachably connected. This connection enhances the connection strength between the first and second components and restricts their relative movement. In practical implementation, the first conductive part is inserted into the second conductive part. After the first and second components are assembled, the first and second conductive parts are soldered together to secure them. This achieves electrical connection between the first and second conductive parts while preventing the first conductive part from detaching from the second conductive part. The detachable connection between the first and second insulating components allows for assembly of the first and second components. Furthermore, the connection between the first and second insulating components reduces the stress on the welded joints, lowering the risk of breakage due to weak welding.
[0030] Furthermore, the auxiliary lead-out terminal, conductive sheet, and first conductive part are formed into an integral structure, avoiding joints between two adjacent conductive parts. This helps improve the reliability of the electrical connection between the auxiliary lead-out terminal and the first conductive part. In actual processing, the auxiliary lead-out terminal, conductive sheet, and first conductive part can be formed on the same conductive sheet, which is convenient for processing.
[0031] Furthermore, the auxiliary lead-out terminal, the first conductive part, and the conductive sheet are all integrally formed on the first insulating member. This allows the first insulating member to fix the auxiliary lead-out terminal, the first conductive part, and the conductive sheet in place, reducing the risk of short circuits caused by movement of the conductive components on the first insulating member during use. In addition, integrally forming the auxiliary lead-out terminal, the first conductive part, and the conductive sheet on the first insulating member facilitates automated processing and improves manufacturing efficiency.
[0032] Furthermore, the coil lead-out terminal, the second conductive part, the auxiliary pin, and the coil pin are all integrally formed on the second insulating part. This forming method can fix the coil lead-out terminal, the second conductive part, the auxiliary pin, and the coil pin on the second insulating part, so that the auxiliary pin and the coil pin are firmly attached to the second insulating part. This effectively restricts the displacement of the auxiliary pin and the coil pin relative to the second insulating part, which helps to improve the installation accuracy of the auxiliary pin and the coil pin. In this way, when assembling the external connector with the relay, the auxiliary pin and the coil pin can accurately plug and match with the conductive plug in the external connector, further preventing the pin from scratching the conductive plug.

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.

[0050] 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.
[0051] 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.
[0052] 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.

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.
[0054] See Figures 1 to 4 , Figure 1 A perspective view of a relay at an angle according to an embodiment of this application is shown; Figure 2 A cross-sectional view of an embodiment of a relay is shown. Figure 3 A perspective view of an embodiment of a relay after the housing has been removed is shown at one angle; Figure 4 A perspective view of an embodiment of a relay with the housing removed is shown from another angle. In this embodiment, a relay is provided, including a housing 7, a relay body 200, and a lead-out assembly for a coil and auxiliary contacts (hereinafter referred to as lead-out assembly 100). The relay body 200 includes auxiliary terminals, an insulating cover 4, a magnetic circuit portion, a main stationary contact 6a, a driving contact 6b, an auxiliary moving contact 3b, a pushing component 9, and a yoke plate 8. In this embodiment, all auxiliary terminals are auxiliary stationary contacts 3a. The yoke plate 8 is connected to the bottom of the insulating cover 4 and forms a cavity 201 with the insulating cover 4. The auxiliary stationary contact 3a and the main stationary contact 6a are both located at the top of the insulating cover 4, and the bottoms of the auxiliary stationary contact 3a and the main stationary contact 6a extend into the cavity 201. The active contact 6b and the auxiliary moving contact 3b are both located inside the cavity 201, and the active contact 6b and the auxiliary moving contact 3b are both connected to the pushing component 9. The movement of the pushing component 9 drives the active contact 6b and the auxiliary stationary contact 3a to move, so that the active contact 6b moves toward or away from the main stationary contact 6a, and the auxiliary moving contact 3b moves toward or away from the auxiliary stationary contact 3a, thereby realizing the contact or separation of the active contact 6b and the main stationary contact 6a, and the contact or separation of the auxiliary moving contact 3b and the auxiliary stationary contact 3a. The magnetic circuit includes a coil assembly 5 and a moving iron core 10 disposed on the lower side of the yoke plate 8. The moving iron core 10 is movably disposed in the coil assembly 5. One end of the pushing member 9 away from the active contact 6b passes through the yoke plate 8 and is connected to the moving iron core 10.
[0055] Reference Figure 3 The leading component 100 includes a first component 1 and a second component 2. (See reference...) Figure 5 , Figure 5This diagram shows a perspective view of a lead-out assembly according to an embodiment of this application. The first assembly 1 includes a first insulating member 11, an auxiliary lead-out terminal 12 connected to one end of the first insulating member 11, and a first conductive portion 13 connected to the other end of a second insulating member 21. The first conductive portion 13 is electrically connected to the auxiliary lead-out terminal 12, and at least partially protrudes from the outside of the first insulating member 11. The auxiliary lead-out terminal 12 is used to connect to the auxiliary stationary contact 3a of the relay body 200. The second assembly 2 includes a second insulating member 21 and coil lead-out terminals 22, second conductive portions 23, auxiliary pins 24, and coil pins 25, all disposed on the second insulating member 21. The coil lead-out terminal 22 is used to connect to the coil assembly 5 of the relay. The coil pins 25 are electrically connected to the coil lead-out terminal 22. The auxiliary pins 24 are electrically connected to the second conductive portion 23, and the second conductive portion 23 is used to connect to the first conductive portion 13.
[0056] In this embodiment, the relay has two auxiliary stationary contacts 3a, and two auxiliary leads 12, two first conductive parts 13, two second conductive parts 23, two auxiliary pins 24, two coil leads 22, and two coil pins 25. Each auxiliary lead 12 corresponds to one auxiliary stationary contact 3a, one first conductive part 13, one second conductive part 23, and one auxiliary pin 24. Each coil lead 22 corresponds to one coil pin 25. Of course, in other embodiments, the number of any of the auxiliary stationary contacts 3a, auxiliary leads 12, first conductive parts 13, second conductive parts 23, auxiliary pins 24, coil leads 22, and coil pins 25 can be flexibly adjusted as needed, and the specific number is not limited here. For example, the number of auxiliary stationary contacts 3a, auxiliary leads 12, first conductive parts 13, second conductive parts 23, auxiliary pins 24, coil leads 22, and coil pins 25 can all be set to one, two, or three, etc. There are no specific limitations on the number of auxiliary stationary contact 3a, auxiliary lead-out terminal 12, first conductive part 13, second conductive part 23, auxiliary pin 24, coil lead-out terminal 22 and coil pin 25.
[0057] It should be noted that in some embodiments, the auxiliary terminal and the auxiliary stationary contact 3a in the relay are two different components, that is, the relay has both an auxiliary terminal and an auxiliary stationary contact 3a, and the auxiliary terminal is electrically connected to the auxiliary stationary contact 3a. In this case, the auxiliary lead-out terminal 12 is used to connect to the auxiliary terminal of the relay.
[0058] In the relays described in this manual, the auxiliary terminal is the auxiliary stationary contact 3a.
[0059] The auxiliary lead-out terminal 12 and the first conductive part 13 are disposed on the first insulating member 11, and the auxiliary coil lead-out terminal 22, the second conductive part 23, the auxiliary pin 24 and the coil pin 25 are disposed on the second insulating member 21. The second conductive part 23 is provided for electrical connection with the first conductive part 13. In this way, the first component 1 and the second component 2 can be assembled during the assembly of the lead-out assembly 100 to the relay body 200. For example, the auxiliary lead-out terminal 12 in the first component 1 is first connected to the auxiliary stationary contact 3a, and then the second conductive part 23 is connected to the first conductive part 13 to realize the assembly of the first component 1 and the second component 2. At the same time, the auxiliary coil lead-out terminal 22 in the second component 2 is connected to the coil assembly 5. Alternatively, the auxiliary coil lead-out terminal 22 in the second component 2 is first connected to the coil assembly 5, and then the first conductive part 13 is electrically connected to the second conductive part 23 to realize the assembly of the first component 1 and the second component 2. At the same time, the auxiliary lead-out terminal 12 in the first component 1 is connected to the auxiliary stationary contact 3a. In this type of lead-out assembly 100, since the auxiliary lead-out terminal 12 is located in the first assembly 1, the auxiliary coil lead-out terminal 22 is located in the second assembly 2, and the second conductive part 23 is used for electrical connection with the first conductive part 13, when assembling the lead-out assembly 100 with the relay body 200, the first assembly 1 and the second assembly 2 can be assembled separately with the relay body 200, and then the first assembly 1 and the second assembly 2 can be assembled together (that is, the second conductive part 23 is electrically connected to the first conductive part 13). During assembly, the mutual influence between the first assembly 1 and the second assembly 2 is small, which is beneficial to improving the relationship between the auxiliary stationary contact and the auxiliary lead-out terminal 12, as well as the line... The precise fit between the lead-out terminal 22 and the coil assembly 5, and between the auxiliary lead-out terminal 12 and the coil lead-out terminal 22, facilitates the connection of the auxiliary lead-out terminal 12 to the auxiliary stationary contact 3a and the connection of the auxiliary coil lead-out terminal 22 to the coil assembly 5. The provision of a second conductive part 23 for electrical connection with the first conductive part 13 allows for the assembly of the first component 1 and the second component 2 during assembly into the relay body 200. Therefore, the precision requirements for the lead-out assembly 100 are lower, and the auxiliary lead-out terminal 12 and the auxiliary pin 24 can be manufactured separately, reducing the manufacturing difficulty of the lead-out assembly 100. Furthermore, when the assembly directions of the auxiliary lead-out terminal 12 and the auxiliary stationary contact 3a, and the coil lead-out terminal 22 and the coil assembly 5 are inconsistent, the first component 1 and the second component 2 can be connected to the relay body 200 separately during assembly of the lead-out assembly 100, avoiding interference between them and reducing assembly difficulty, thus facilitating relay assembly.In addition, placing both the auxiliary pin 24 and the coil pin 25 on the second insulating member 21 helps to improve the mating accuracy of the auxiliary pin 24 and the coil pin 25. When mating with the external connector, it prevents the auxiliary pin 24 and the coil pin 25 from rubbing against the conductive plug of the external connector and generating metal shavings, thereby reducing the risk of two adjacent pins becoming conductive due to scraping.
[0060] In some embodiments, the second conductive part 23 contacts the first conductive part 13, so that the first conductive part 13 and the second conductive part 23 are in direct contact, thereby achieving an electrical connection between the second conductive part 23 and the first conductive part 13.
[0061] In some embodiments, reference is made to Figure 7 , Figure 10 and Figure 11 One of the second conductive part 23 and the first conductive part 13 is inserted into the other. In this embodiment, the first conductive part 13 is inserted into the second conductive part 23. The first conductive part 13 is a conductive plug, and the second conductive part 23 is a conductive socket. The second conductive part 23 is provided with a socket 231, into which the first conductive part 13 is inserted. In actual implementation, the size of the socket 231 is larger than the cross-sectional size of the first conductive part 13. When the lead-out assembly 100 is assembled with the relay body 200, the first conductive part 13 and the second conductive part 23 are soldered to fix them, so that the second conductive part 23 and the first conductive part 13 are electrically connected. This allows for a larger space in the socket 231 for the insertion of the first conductive part 13, which is beneficial for the first conductive part 13 to be inserted into the second conductive part 23. In addition, it can reduce the processing accuracy requirements of the first conductive part 13 and the socket 231, and further reduce the assembly difficulty of the lead-out assembly 100 and the relay body 200.
[0062] Of course, in other implementations, the size of the socket 231 can be set to be equal to or slightly smaller than the cross-sectional size of the first conductive part 13. When the first conductive part 13 is inserted into the socket 231, the first conductive part 13 is inserted into the socket 231 by external force, so that the first conductive part 13 is connected to the second conductive part 23.
[0063] In other embodiments, the second conductive part 23 and the first conductive part 13 may also be electrically connected through other structures, such as threaded structures. There are no specific restrictions on the way the second conductive part 23 and the first conductive part 13 are electrically connected.
[0064] Understandably, the first insulating member 11 provides support and positioning for the auxiliary lead-out terminal 12 and the first conductive part 13, and the second insulating member 21 provides support and positioning for the auxiliary coil lead-out terminal 22, the second conductive part 23, the auxiliary pin 24, and the coil pin 25. In this embodiment, the first insulating member 11 and the second insulating member 21 are detachably connected. The connection between the first insulating member 11 and the second insulating member 21 enhances the connection strength between the first component 1 and the second component 2 and restricts the relative movement of the first insulating member 11 and the second insulating member 21. In actual implementation, the first conductive part 13 is inserted into the second conductive part 23. After the first component 1 and the second component 2 are assembled together, the first conductive part 13 and the second conductive part 23 are soldered together to fix them. This achieves electrical connection between the first conductive part 13 and the second conductive part 23 while preventing the first conductive part 13 from detaching from the second conductive part 23. The first insulating part 11 and the second insulating part 21 are detachable. Based on the ability to connect the first component 1 and the second component 2 to the relay body 200 separately, the connection of the first insulating part 11 and the second insulating part 21 can reduce the stress on the solder joint between the first conductive part 13 and the second conductive part 23, and reduce the risk of breakage due to weak soldering.
[0065] In some embodiments, at least a portion of the first conductive portion 13 protrudes outside the first insulating member 11 to facilitate insertion of the second conductive portion 23 into the first conductive portion 13.
[0066] Of course, in actual implementation, at least a portion of the second conductive part 23 may be provided to protrude outside the second insulating member 21 as needed; or, at least a portion of the first conductive part 13 may be provided to protrude outside the first insulating member 11, and at least a portion of the second conductive part 23 may protrude outside the second insulating member 21.
[0067] In some embodiments, refer to Figures 1 to 4 The lead-out assembly 100 is disposed on one side of the coil assembly 5. The coil assembly 5 includes a coil component and a circuit board 51 electrically connected to the coil component. The coil component is disposed on one side of the lead-out assembly 100, and the circuit board 51 is disposed between the lead-out assembly 100 and the coil component. The coil lead-out terminal 22 is inserted into the circuit board 51 to realize the electrical connection between the coil lead-out terminal 22 and the coil assembly 5. By placing the circuit board 51 between the lead-out assembly 100 and the coil component, the space between the lead-out assembly 100 and the coil component can be utilized, making the internal structure of the relay more compact and facilitating the miniaturization design of the relay.
[0068] Among them, see Figure 2The coil component includes a coil frame 53 and a coil 52 wound on the coil frame 53. The top of the coil frame 53 is connected to the yoke plate 8. The moving iron core 10 is movably disposed in the inner hole of the coil frame 53. One end of the pushing member 9 away from the active contact 6b passes through the yoke plate 8 and is connected to the moving iron core 10.
[0069] Relays in some embodiments, see Figure 2 The insulating cover 4, auxiliary stationary contact 3a, coil 52, circuit board 51, and first insulating member 11 are all disposed inside the housing 7. The auxiliary stationary contact 3a protrudes from the top of the insulating cover 4. The housing 7 is provided with a connector 71. The end of the auxiliary pin 24 away from the second insulating member 21 and the end of the coil pin 25 away from the second insulating member 21 are both disposed in the connector 71. The connector 71 is provided to provide space for the connection between the relay and the external connector, and also to provide space for the lead-out of the auxiliary pin 24 and the coil pin 25.
[0070] Further, see Figure 1 and Figure 2 The housing 7 also includes a first housing segment 73 and a second housing segment 74 disposed on the first housing segment 73. The auxiliary stationary contact 3a, the insulating cover 4, the coil component, the circuit board 51, the first insulating element 11 and the second insulating element 21 are all disposed inside the first housing segment 73. The second housing segment 74 is provided with a plug-in interface 71. An opening 72 is provided between the first housing segment 73 and the second housing segment 74. The opening 72 connects the interior of the first housing segment 73 and the plug-in interface 71. A portion of the second insulating element 21 is located in the opening 72. One end of the auxiliary pin 24 and one end of the coil pin 25 are both connected to the second insulating element 21. The other end of the auxiliary pin 24 and the other end of the coil pin 25 protrude from the portion of the second insulating element 21 located in the opening 72 and extend into the plug-in interface 71. The other end of the auxiliary pin 24 and the other end of the coil pin 25 both protrude from the part of the second insulating member 21 located in the opening 72 and extend into the plug interface 71. The second insulating member 21 can be used to protect the part of the auxiliary pin 24 and the coil pin 25 located in the opening 72. In this way, when the housing 7 is assembled onto the relay body 200, the side wall of the opening 72 is prevented from scratching the pins, thus avoiding scratching.
[0071] See Figure 2 The first shell component 73 includes a cover 732 and a base 731 disposed at one end of the cover 732, and the second shell component 74 is disposed on the cover 732.
[0072] In some embodiments, reference is made to Figure 9 and Figure 10One of the first insulating member 11 and the second insulating member 21 is provided with a first insertion protrusion 15, and the other is provided with a first insertion hole 27. The first insertion protrusion 15 is inserted into the first insertion hole 27. The arrangement of the first insertion protrusion 15 and the first insertion hole 27 facilitates the positioning and assembly of the first insulating member 11 and the second insulating member 21, and also allows the first conductive part 13 to be quickly inserted into the second conductive part 23. In this embodiment, the first insertion hole 27 is a blind hole; however, in other embodiments, the first insertion hole 27 can also be a through hole.
[0073] In this example, the first insertion protrusion 15 is disposed on the first insulating member 11, and the first insertion hole 27 is disposed on the second insulating member 21.
[0074] In another example, the first insertion protrusion 15 can be disposed on the second insulating member 21, and the first insertion hole 27 can be disposed on the first insulating member 11. In actual implementation, the positions of the first insertion protrusion 15 and the first insertion hole 27 can be flexibly selected as needed. There are no specific restrictions on the positions of the first insertion protrusion 15 and the first insertion hole 27 here.
[0075] Reference Figures 3 to 5 The first insulating member 11 includes a first split 111 and a second split 112. The second split 112 is connected to the first split 111 and forms an angle with the first split 111. A first conductive part 13 and a first insertion protrusion 15 are both located at the end of the first split 111 away from the second split 112. An auxiliary lead-out terminal 12 is located at the end of the second split 112 away from the first split 111. In this example, the auxiliary lead-out terminal 12 is located above the second insulating member 21, and the first split 111 and the second split 112 are connected at a 90° angle. In actual implementation, the angle between the first split 111 and the second split 112 can be flexibly adjusted as needed, for example, the angle between the first split 111 and the second split 112 can be set to 30°, 60°, or 120°, etc. Setting the first split 111 and the second split 112 at an angle facilitates the arrangement of the auxiliary lead-out terminal 12 and the first conductive part 13, thereby optimizing the overall structure of the lead-out assembly 100, so that the auxiliary lead-out terminal 12 can be connected with the auxiliary stationary contact 3a and the first conductive part 13 can be inserted into the second conductive part 23.
[0076] Reference Figure 8 and Figure 9 The first part 111 is provided with a reinforcing part 114 at the end away from the second part 112. The reinforcing part 114 protrudes from one side of the first part 111 in the thickness direction. The first conductive part 13 is provided on the reinforcing part 114. The provision of the reinforcing part 114 increases the space of the first part 111 at the end away from the second part 112, and provides a reserved position for the insertion of the first insertion protrusion 15.
[0077] In this embodiment, the first component 111 and the second component 112 are an integral structure. To reduce the space occupied by the lead-out assembly 100, the thickness of the first insulating member 11 is usually made smaller. However, a thinner first insulating member 11 is prone to breakage at the connection between the first component 111 and the second component 112. Therefore, refer to... Figure 9 A reinforcing rib 113 is provided at the connection between the first component 111 and the second component 112. The reinforcing rib 113 enhances the connection strength between the first component 111 and the second component 112, reducing the risk of breakage of the first insulating component 11. Preferably, multiple reinforcing ribs 113 are provided, and the multiple reinforcing ribs 113 are distributed at intervals along the width direction of the first insulating component 11.
[0078] In some embodiments, reference is made to Figure 6 and Figure 7 The auxiliary lead-out terminal 12 is connected to the first conductive part 13 via a conductive sheet 14. The auxiliary lead-out terminal 12, the conductive sheet 14, and the first conductive part 13 are integrally formed. Forming the auxiliary lead-out terminal 12, the conductive sheet 14, and the first conductive part 13 into an integral structure avoids joints between two adjacent conductive components, which improves the reliability of the electrical connection between the auxiliary lead-out terminal 12 and the first conductive part 13. Furthermore, in actual processing, the auxiliary lead-out terminal 12, the conductive sheet 14, and the first conductive part 13 can be formed on the same conductive sheet, facilitating processing.
[0079] Continue to refer to Figure 6 and Figure 7 The second conductive part 23 and the auxiliary pin 24 are integrated into one piece, and the coil lead terminal 22 and the coil pin 25 are integrated into one piece. Making the two electrically connected conductive parts into one piece facilitates manufacturing and reduces the number of joints between the connected conductive parts.
[0080] Reference Figure 8 The auxiliary lead-out terminal 12, the first conductive part 13, and the conductive sheet 14 are all integrally formed on the first insulating member 11. This allows the first insulating member 11 to fix the auxiliary lead-out terminal 12, the first conductive part 13, and the conductive sheet 14, reducing the risk of short circuits caused by movement of the conductive components on the first insulating member 11 during use. Furthermore, integrally forming the auxiliary lead-out terminal 12, the first conductive part 13, and the conductive sheet 14 on the first insulating member 11 facilitates automated processing and improves manufacturing efficiency.
[0081] Understandably, the relay is used in conjunction with an external connector. The external connector has multiple conductive plugs; there are two auxiliary pins 24 and two coil pins 25. Each auxiliary pin 24 and coil pin 25 corresponds one-to-one with a conductive plug on the external connector. Each auxiliary pin 24 and coil pin 25 is plugged into its corresponding conductive plug to achieve connection between the relay and the external connector. (Refer to...) Figure 10 The coil lead terminal 22, the second conductive part 23, the auxiliary pin 24, and the coil pin 25 are all integrally formed on the second insulating member 21. This forming method can fix the coil lead terminal 22, the second conductive part 23, the auxiliary pin 24, and the coil pin 25 on the second insulating member 21, so that the auxiliary pin 24 and the coil pin 25 are firmly attached to the second insulating member 21. This effectively restricts the displacement of the auxiliary pin 24 and the coil pin 25 relative to the second insulating member 21, which helps to improve the positional accuracy of the auxiliary pin 24 and the coil pin 25. In this way, when assembling the external connector with the relay, the auxiliary pin 24 and the coil pin 25 can accurately plug and cooperate with the conductive plug in the external connector, further preventing the pin from scratching the conductive plug.
[0082] In some embodiments, when all conductive plugs on the external connector are arranged sequentially at intervals along the same direction, refer to Figure 10 When both the auxiliary pin 24 and the coil pin 25 are integrally formed in the second insulating member 21, the auxiliary pin 24 and the coil pin 25 are spaced apart along the same direction. Since both the auxiliary pin 24 and the coil pin 25 are integrally formed in the second insulating member 21, they can be firmly bonded to the second insulating member 21. This reduces the risk of displacement of the pins relative to the second insulating member 21, thus ensuring that all auxiliary pins 24 and coil pins 25 are located on the same plane. This facilitates adaptation to the positions of various conductive plugs on the external connector and prevents scratching between the pins and conductive plugs.
[0083] Continue to refer to Figure 10 The second insulating component 21 is provided with a second insertion protrusion 26. The second insertion protrusion 26 and the coil lead-out terminal 22 are both located on the same side of the second insulating component 21. The second insertion protrusion 26 is used to insert into the circuit board 51 of the coil assembly 5. It can be understood that the circuit board 51 is provided with a second insertion hole (not shown in the figure) corresponding to the second insertion protrusion 26. By engaging the second insertion protrusion 26 in the second insertion hole, the position of the second insulating component 21 and the circuit board 51 is relatively fixed, which is beneficial to the assembly of the lead-out assembly 100 and the coil assembly 5.
[0084] 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.

[0085] The above embodiments merely illustrate 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.
