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

[0003] Typically, a relay's lead-out terminals are electrically connected to the contacts on one end inside the housing, while the other extends through the housing for external wires. However, with increasing demands for current-carrying capacity, relays are often larger, making it difficult to ensure the stability of the lead-out terminals.

[0069] A relay is an electronic control device that provides automatic regulation, safety protection, and circuit switching within a circuit. Typically, one end of a relay's lead is electrically connected to the contacts inside the housing, while the other end extends through the housing and connects to an external wire. However, with increasing demands for current-carrying capacity, relays are often larger, making it difficult to ensure the stability of the lead, which in turn affects contact clearance and performance.

[0070] For this purpose, see Figures 1 to 5 , the present application provides a relay 10. Figure 1 Schematic diagram of a relay 10 according to an embodiment of the present application. Figure 2 for Figure 1 The schematic diagram of the relay 10 shown is shown with the cover 500 removed. Figure 3 for Figure 2 The top view of the relay 10 is shown. Figure 4 for Figure 2 The schematic diagram of the contact assembly 200, the lead terminal 300 and the positioning member 400 in the relay 10 is shown. Figure 5 for Figure 4 The diagram shows the contact assembly 200 mating with the lead end 300 .

[0071] The relay 10 has a lead 300 through which an external wire is connected. The relay 10 of the present application can accurately position the lead 300, thereby improving the assembly accuracy of the lead 300 and the reliability of the contact gap, thereby ensuring the performance of the relay 10. The following describes the specific structure of the relay 10 in some embodiments.

[0072] See Figures 1 to 5 In one embodiment, the relay 10 includes a housing 100, a contact assembly 200, a lead terminal 300, and a positioning member 400. The contact assembly 200 is disposed in the housing 100. The lead terminal 300 has one end disposed in the housing 100 and electrically connected to the contact assembly 200, and the other end extending through the housing 100. The positioning member 400 is fixedly mounted to the housing 100 and connected to the lead terminal 300 to position the lead terminal 300, thereby at least positioning the contact gap of the contact assembly 200.

[0073] Housing 100 serves as the mounting base for relay 10. Contact assembly 200 and lead terminal 300 are housed within housing 100. Housing 100 protects contact assembly 200 and lead terminal 300, ensuring safe operation of relay 10. Contact assembly 200 serves as the reed structure of relay 10. One end of lead terminal 300 can be electrically connected to contact assembly 200, while the other end can extend through housing 100, allowing lead terminal 300 to be partially located inside and partially outside housing 100.

[0074] Thus, the end of the lead-out terminal 300 outside the housing 100 can be connected to a wire to connect the relay 10 to the circuit. The contact assembly 200 can be closed or opened to close or open the relay 10. When the contact assembly 200 is closed, the relay 10 is in the closed state, thereby conducting the circuit. When the contact assembly 200 is opened, the relay 10 is in the open state, thereby breaking the circuit.

[0075] As will be understood, the lead-out terminal is directly connected to the contact assembly, and the positioning accuracy of the lead-out terminal directly affects the gap between the contacts in the contact assembly. If the lead-out terminal positioning reliability is poor, the contact gap will be affected, and thus the closing or opening of the contacts will be affected. To this end, the relay 10 of the present application also includes a positioning member 400. The positioning member 400 can be connected to the lead-out terminal 300. In this way, the lead-out terminal 300 can be positioned by the positioning member 400, thereby positioning at least the contact gap of the contact assembly 200 to ensure the positioning accuracy of the lead-out terminal 300.

[0076] The positioning member 400 is provided separately from the housing 100 and can be fixedly mounted to the housing 100. The positioning member 400 is molded and processed separately from the housing 100, making it smaller in size and having fewer assembled parts than the housing 100. This facilitates the control of the positioning member 400's accuracy and ensures its structural strength, making it less prone to deformation.

[0077] In this way, the housing 100 can position the positioning member 400, and the positioning member 400 can position the lead terminal 300, so that the lead terminal 300 is accurately positioned relative to the housing 100, thereby improving the assembly accuracy of the lead terminal 300 and at least locating the contact gap of the contact assembly 200. In this way, the positioning member 400 can improve the reliability of the positioning of the lead terminal 300 in the contact direction of the contact assembly 200, ensure the accuracy of the contact gap, improve the reliability of the contact gap, avoid affecting the closing or opening of the contacts, and thus ensure the performance of the relay 10.

[0078] See Figures 2 to 5In one embodiment, the contact assembly 200 includes a movable contact 210 and a stationary contact 220, which are disposed opposite each other in the housing 100. The movable contact 210 is movably disposed in the housing 100, while the stationary contact 220 is fixedly disposed in the housing 100. The movable contact 210 and the stationary contact 220 are disposed opposite each other. The movable contact 210 can move toward or away from the stationary contact 220 to close or open the movable contact 210 and the stationary contact 220, thereby closing or opening the relay 10.

[0079] In one embodiment, the relay 10 has a first direction, a second direction, and a third direction. Figures 1 to 3 As shown, the first direction is the extension direction of the dynamic contact 210, the second direction is the contact direction between the dynamic contact 210 and the static contact 220, and the third direction is a direction perpendicular to the first direction and the second direction. The dynamic contact 210 can close or open with the static contact 220 along the second direction (contact direction, which will not be repeated later). This application only uses Figures 1 to 3 The first direction, second direction and third direction shown describe the structure of the relay 10. The relay 10 and its components are arranged according to the first direction, second direction and third direction, which will be directly used hereinafter.

[0080] In one embodiment, the movable contact 210 includes a movable spring 212 and a movable contact 211. The movable spring 212 is movably disposed in the housing 100 along a second direction, and the movable contact 211 is disposed on the movable spring 212. The static contact 220 includes a static contact 221, which is riveted to the housing 100 and disposed opposite the movable contact 211. The movable spring 212 is movable in the second direction to close or open the movable contact 211 and the static contact 221, thereby closing or opening the movable contact 210 and the static contact 220, and thereby closing or opening the relay 10.

[0081] In one embodiment, the lead-out terminal 300 is connected to the dynamic contact 210 and / or the static contact 220. In this embodiment, the lead-out terminal 300 is connected to the dynamic contact 210 and the static contact 221. Of course, in other embodiments of the present application, the lead-out terminal 300 may also be connected to the static contact 220 or to both the dynamic contact 210 and the static contact 220.

[0082] Exemplarily, the lead-out terminal 300 is connected to the movable spring 212 and the static contact 221. The movable spring 212 is riveted to the lead-out terminal 300, and the static contact 221 passes through the movable spring 212 and is riveted to the lead-out terminal 300. In this way, after the lead-out terminal 300 extends through the housing 100, the lead-out terminal 300 is connected to a wire to connect the movable spring 212 to the circuit. Optionally, the lead-out terminal 300 can be an integral structure with the movable spring 212. Of course, in other embodiments of the present application, the lead-out terminal 300 and the movable spring 212 can also be provided separately and reliably connected by riveting or other methods. In this embodiment, the static contact 221 is riveted separately and fixedly connected to the lead-out terminal 300. Of course, in other embodiments of the present application, the static contact 221 can also be integrally formed with the lead-out terminal 300.

[0083] In one embodiment, the relay 10 further includes a drive structure (not shown) disposed within the housing 100 and capable of abutting against the movable reed 212. The drive structure is capable of driving the movable reed 212 to move in the second direction, thereby closing or opening the movable contact 211 with the stationary contact 221. The drive structure is the power source for the relay 10, and the drive structure controls the movement of the movable reed 212 to achieve closing or opening control of the relay 10. In other embodiments, the drive structure may indirectly push or pull the movable reed 212 via a push-pull structure.

[0084] In this embodiment, the driving structure is a magnetic circuit structure, and the coil and the armature assembly cooperate to drive the movement of the movable spring 212. Of course, in other embodiments of the present application, the driving structure can also be other structures capable of driving the movement of the movable spring 212, such as a motor.

[0085] It is worth noting that the focus of this application is on the positioning of the lead-out terminal 300 by the positioning member 400, and the coordination between the lead-out terminal 300 and the positioning member 400 and the housing 100. The structure of the driving structure, the structural principle of the driving structure driving the dynamic reed 212 to move, and the structure and principle of the dynamic contact 210 and the static contact 220 are not the focus of this application and will not be explained in this application.

[0086] See Figures 2 to 5 In one embodiment, the positioning member 400 is located near the connection between the lead terminal 300 and the contact assembly 200 and is used to position the side of the lead terminal 300 closest to the contact assembly 200. In other words, after the positioning member 400 is connected to the lead terminal 300, it can be close to the movable contact 211 and the stationary contact 221. In this way, the positioning member 400 can position the lead terminal 300 near the movable contact 211 and the stationary contact 221, ensuring an accurate gap between the movable contact 211 and the stationary contact 221. This improves the reliability of the contact gap, reduces the risk of affecting contact closure or opening, and thus ensures the performance of the relay 10.

[0087] See Figures 2 to 5 In one embodiment, the positioning member 400 is located inside the housing 100. That is, the positioning member 400 is fixedly mounted in the housing 100. The positioning member 400 positions the lead terminal 300 inside the housing 100 to improve the assembly accuracy of the lead terminal 300. At the same time, the positioning member 400 can also be placed close to the movable contact 211 and the stationary contact 221 to ensure an accurate gap between the movable contact 211 and the stationary contact 221, thereby improving the reliability of the contact gap and thus ensuring the performance of the relay 10.

[0088] Of course, in other embodiments of the present application, the positioning member 400 may also be located outside the housing 100. In other words, the positioning member 400 is fixedly mounted outside the housing 100, and the positioning member 400 positions the lead-out terminal 300 outside the housing 100. In this way, the positioning member 400 can also achieve positioning of the lead-out terminal 300, thereby improving the assembly accuracy of the lead-out terminal 300.

[0089] It is worth noting that the structure of the positioning member 400 on the outside of the shell 100 and the connection principle with the lead-out terminal 300 are essentially the same as those of the positioning member 400 on the inside of the shell 100. The following text will only use the positioning member 400 on the inside of the shell 100 as an example for explanation, and will not go into details about the positioning member 400 on the outside of the shell 100.

[0090] See Figure 2 、 Figure 6 In one embodiment, the housing 100 includes a bottom plate 110 and a plurality of side plates 120. The side plates 120 are mounted on the bottom plate 110 and define a mounting space therewith. The side plates 120 have mounting locations 121, which are open slots on the side of the side plates 120 facing away from the bottom plate 110. The lead-out terminals 300 are perpendicular to the bottom plate 110 and extend through the mounting locations 121 to extend out of the side plates 120. Figure 6 for Figure 2 A schematic diagram of the housing 100 in the relay 10 is shown.

[0091] The bottom plate 110 serves as the base of the housing 100. Multiple side panels 120 are positioned at the edges of the bottom plate 110. The edges of adjacent side panels 120 are connected, forming the housing 100 into a box-like structure. Thus, the multiple side panels 120 and the bottom plate 110 enclose an installation space. The dynamic contact 210, the static contact 220, the lead terminal 300, and the positioning member 400 are positioned within the installation space. The dynamic contact 210 and the static contact 220 are closed or disconnected within the installation space. The lead terminal 300 connects to the dynamic reed 212 within the installation space. The positioning member 400 positions the lead terminal 300 within the installation space.

[0092] Furthermore, the mounting position 121 extends through the side panel 120 in a first direction and has a certain depth in a third direction, thereby forming an open groove above the side panel 120. The mounting position 121 is connected to the mounting space, thereby connecting the mounting space on the outside and inside of the housing 100. The lead-out terminal 300 can extend through the mounting position 121. In this case, the lead-out terminal 300 can be perpendicular to the bottom panel 110. In this way, the lead-out terminal 300 is in an upright position relative to the bottom panel 110, so that the lead-out terminal 300 extends vertically out of the housing 100, reducing the horizontal space occupied by the lead-out terminal 300. This facilitates the design of more lead-out terminals 300 on the side of the housing 100 to meet the needs of different working conditions. Optionally, the lead-out terminal 300 can also be perpendicular to the bottom panel 110 and the side panel 120.

[0093] For today's large, tall relays, their housings are typically injection molded. During molding, a deep opening is reserved in the side panels of the housing, through which the vertical terminals are routed. However, the housing's height creates a large chamfer during demolding, resulting in inaccurate opening dimensions. Once the terminals are installed in the opening, their positioning reliability is poor, which in turn affects the gap between the contacts.

[0094] To this end, the present application employs a positioning member 400 to position the lead-out terminal 300. The lead-out terminal 300 extends only through the mounting position 121 of the side panel 120, eliminating the need for the inner wall of the mounting position 121 to position the lead-out terminal 300. This ensures the assembly accuracy of the lead-out terminal 300 and, in turn, the reliable clearance between the moving contact 211 and the static contact 221. Furthermore, during the molding of the housing 100, there is no need to control numerous dimensions, which reduces the molding difficulty of the housing 100 and facilitates the molding of the housing 100.

[0095] Furthermore, for conventional large, high-profile relays, after the lead terminals extend through openings in the housing, they are typically riveted to multiple sets of moving springs. When the moving and static contacts close or open, the lead terminals are subject to significant reaction forces, which act on the side panels of the housing, providing adequate support for the lead terminals. However, due to the deep openings in the side panels, the force applied to the lead terminals easily deforms, resulting in insufficient support from the side panels.

[0096] To this end, the present application utilizes a positioning member 400 to position the lead terminal 300 in the contact direction between the dynamic contact 210 and the static contact 220. The positioning member 400 is fixedly mounted on the bottom plate 110 of the housing 100. The positioning member 400 is capable of positioning the lead terminal 300, that is, positioning the positioning member 400 through the bottom plate 110, thereby positioning the lead terminal 300. When the reaction force generated by the closing or opening of the dynamic contact 210 and the static contact 220 acts on the lead terminal 300, the positioning member 400, due to its good strength and resistance to deformation, can provide sufficient support for the lead terminal 300.

[0097] Thus, even if the mounting position 121 on the side panel 120 is deep, the side panel 120 does not need to support the lead-out terminal 300, thus preventing deformation of the side panel 120 and ensuring the structural strength of the housing 100. At the same time, the positioning member 400 can provide positioning accuracy and reliable support for the lead-out terminal 300 in the contact direction, thereby achieving accurate positioning of the lead-out terminal 300 and ensuring the reliability of the contact gap.

[0098] See Figure 6 In one embodiment, the bottom plate 110 has a positioning component, and the positioning component 400 is assembled with the positioning component to position the lead-out terminal 300 in the housing. In this way, the positioning component 400 is positioned and installed on the bottom plate 110 of the housing 100 through the positioning component. The positioning component 400 is positioned by the bottom plate 110 to achieve the relative positioning of the lead-out terminal 300 in the housing 100. After the lead-out terminal 300 is subjected to force and transmitted to the positioning component 400, the force of the positioning component 400 can be transmitted to the bottom plate 110, and the strength of the bottom plate 110 is relatively reliable and not easily deformed, which can achieve reliable positioning of the positioning component 400, improve the positioning accuracy of the positioning component 400 in the housing 100, and thus improve the positioning accuracy of the lead-out terminal 300. Optionally, the positioning component is a protrusion or a groove, and the positioning component is provided on the positioning component 400. A structure that cooperates with the positioning component is provided.

[0099] See Figures 2 to 5 In one embodiment, the contact assembly 200 includes a plurality of dynamic contacts 210 and a plurality of static contacts 220. The plurality of dynamic contacts 210 are arranged at intervals in the housing 100, and each static contact 220 is arranged opposite to the corresponding dynamic contact 210. When the dynamic contact 210 moves, it can close or open with the corresponding static contact 220. The provision of multiple dynamic contacts 210 and multiple static contacts 220 in the relay 10 increases the current carrying capacity of the relay 10 while helping to reduce temperature rise, allowing the relay 10 to withstand greater current to meet the needs of high-current electrical equipment and ensure the performance of the relay 10. The multiple dynamic contacts 210 are arranged at intervals in the housing 100 and are arranged one-to-one with the multiple static contacts 220. In this way, each dynamic contact 210 can close or open with the corresponding static contact 220.

[0100] In one embodiment, the lead terminal 300 is connected to the dynamic contact 210, and the positioning member 400 is capable of supporting the lead terminal 300 in the contact direction between the dynamic contact 210 and the static contact 220. The dynamic spring 212 is capable of moving in a second direction to close or open the dynamic contact 211 and the static contact 221 along the contact direction. It will be appreciated that the lead terminal 300 and the dynamic spring 212 are fixedly connected, such as by riveting, to enhance the structural strength of the connection between the lead terminal 300 and the dynamic contact 210.

[0101] When the movable contact 211 and the stationary contact 221 are closed or open, the movable spring 212 is subjected to a certain force. This force can cause the lead terminal 300 to wobble in the contact direction, affecting the contact gap. The positioning member 400 supports the lead terminal 300 in the contact direction, limiting its displacement along the contact direction. This allows for positioning of the lead terminal 300 in the contact direction, improving assembly accuracy and the reliability of the contact gap, thereby ensuring the performance of the relay 10.

[0102] In one embodiment, a plurality of movable contacts 210 are arranged in the housing 100 at intervals along the second direction, and the movable contacts 210 are closed or disconnected with the static contacts 220 along the second direction. The movable spring 212 moves in the second direction to close or disconnect the movable contact 211 with the static contact 221 along the second direction, and the movable contact 210 is closed or disconnected with the static contact 220 along the second direction. In other embodiments of the present application, a plurality of movable contacts 210 can also be arranged in the housing 100 at intervals along a third direction, and the static contacts 220 are arranged corresponding to the movable contacts 210. In this way, the plurality of movable contacts 210 and the plurality of static contacts 220 present a multi-layer structure in the housing 100, and multiple parallel structures can be realized in multiple directions, which makes more reasonable space utilization and avoids excessive volume in a certain direction.

[0103] In this embodiment, multiple movable contacts 210 are spaced apart along the second direction within the housing 100, and each movable contact 210 is connected to a lead terminal 300. In other embodiments, the multiple movable contacts 210 are spaced apart along the second and third directions, so that the multiple movable contacts 210 form a double-layer structure. Each movable contact 210 is connected to a lead terminal 300, and the lead terminals 300 arranged vertically are connected to the circuit through a lead terminal 300 on the outside of the housing 100.

[0104] See Figures 2 to 6In this embodiment, at least a portion of the surface of the bottom plate 110 is perpendicular to the third direction. Thus, a plurality of movable contacts 210 are spaced apart in the housing 100 along the second direction. The movable contacts 210 are positioned perpendicular to the bottom plate 110 and extend along the first direction, so that the movable contacts 210 close or open with the static contacts 220 along the second direction.

[0105] See Figures 2 to 5 In one embodiment, the number of lead-out terminals 300 is greater than or equal to the number of dynamic contacts 210. In this embodiment, the number of lead-out terminals 300 is equal to the number of dynamic contacts 210. Each dynamic spring 212 is connected to a lead-out terminal 300, and the dynamic spring 212 is connected to the circuit through the lead-out terminal 300. Of course, in other embodiments of the present application, the number of lead-out terminals 300 may also be greater than the number of dynamic contacts 210. When multiple dynamic contacts 210 and multiple static contacts 220 are arranged in a multi-layer structure in the housing 100, the lead-out terminals 300 arranged vertically are connected to the circuit through a lead-out terminal 300 on the outside of the housing 100.

[0106] See Figure 5 In one embodiment, the movable spring 212 includes a fixed body and multiple current-conducting branches 2121. The multiple current-conducting branches 2121 are spaced apart from the fixed body along the third direction and extend along the first direction. There are multiple movable contacts 211 and multiple static contacts 221, each of which is provided in a corresponding manner. Each current-conducting branch 2121 is provided with a movable contact 211. Thus, each movable spring 212 is connected to multiple movable contacts 211 via the multiple current-conducting branches 2121, enabling the multiple movable contacts 211 to be closed or opened simultaneously with the multiple static contacts 221. This increases the current-carrying capacity of the relay 10 while also helping to reduce temperature rise.

[0107] In this embodiment, there are four diverting branches 2121, which are spaced apart along the third direction. There are four movable contacts 211 and four static contacts 221. Each diverting branch 2121 is provided with a movable contact 211, and the movable contacts 211 and the static contacts 221 are provided in a one-to-one correspondence. Of course, in other embodiments of the present application, the number of diverting branches 2121 can be other and equal to the number of movable contacts 211 and the static contacts 221.

[0108] See Figure 3 In one embodiment, the mounting body 412 (mentioned later) of the positioning member 400 is spaced apart from the moving contact member 210 along the first direction. In other words, there is a certain distance between the mounting body 412 of the positioning member 400 and the moving contact member 210 in the first direction (as mentioned later). Figure 10In this way, the mounting body 412 does not obstruct the movable contact 210 in the second direction, and thus does not block the movement of the movable contact 210, allowing the movable contact 210 to accurately close or open with the static contact 220 in the second direction. This prevents the positioning member 400 from interfering with the movement of the movable contact 210, thereby ensuring the accuracy of the movement of the movable contact 210. Furthermore, a certain distance exists between the mounting body 412 and the movable contact 210 in the first direction, and both sides of the first direction can be used as positioning features to avoid interference with the movement of the movable contact 210.

[0109] See Figures 2 to 5 In one embodiment, the relay 10 includes at least two terminals 300. A positioning member 400 connects the at least two terminals 300 to position them, thereby at least locating the contact gap of the contact assembly 200. The at least two terminals 300 can be positioned by a single positioning member 400, thereby improving the assembly accuracy of the terminals 300 and reducing the relative mating position of the terminals 300 and the housing 100. In this way, the positioning member 400 can improve the positioning reliability of the terminals 300, ensure accurate contact gap, and thus improve the reliability of the contact gap, thereby preventing interference with contact closing or opening, and thus ensuring the performance of the relay 10.

[0110] See Figures 2 to 5 In one embodiment, at least two lead terminals 300 are disposed on opposite sides of the housing 100, and the positioning member 400 connects to both lead terminals 300. Alternatively, at least one positioning member 400 is used on each side to connect to at least one lead terminal 300. In other words, at least two lead terminals 300 can extend out of the housing 100 on both sides in the width direction. Thus, the at least two lead terminals 300 are located on either side of the relay 10, providing space for connecting wires to the lead terminals 300.

[0111] Moreover, after the at least two lead terminals 300 extend out of the housing 100 in the width direction, the same positioning member 400 can be used to simultaneously connect the at least two lead terminals 300. In this way, the at least two lead terminals 300 can be positioned by the same positioning member 400, thereby improving the positioning accuracy of the at least two lead terminals 300. At the same time, it can also improve assembly efficiency and improve the relative positioning accuracy between the at least two lead terminals 300. Of course, after the at least two lead terminals 300 extend out of the housing 100 in the width direction, at least one positioning member 400 can also be used on each side to connect at least one lead terminal 300, such as using at least one positioning member 400 to connect at least one lead terminal 300 on the front side and using at least one positioning member 400 to connect at least one lead terminal 300 on the rear side, so as to achieve the positioning of the at least two lead terminals 300.

[0112] See Figures 2 to 4In one embodiment, the positioning members 400 on opposite sides are staggered along the second direction. That is, the two positioning members 400 are not collinear in the first direction. This allows the lead terminals 300 to be connected to different movable springs 212 , allowing the positioning members 400 to position the respective lead terminals 300 without interfering with the movement of the movable springs 212 , thereby ensuring that the movable contact 210 and the static contact 220 can normally close or open.

[0113] See Figures 2 to 5 In this embodiment, there are four lead-out terminals 300, and the four lead-out terminals 300 extend out of the shell 100 along the width direction, two of which extend out of the front side of the shell 100, and the other two lead-out terminals 300 extend out of the rear side of the shell 100. There are two positioning members 400, one of which connects the two lead-out terminals 300 on the front side, and the other connects the two positioning members 400 on the rear side. In this way, the two lead-out terminals 300 on the front side are positioned by one positioning member 400, and the two lead-out terminals 300 on the rear side are positioned by the other positioning member 400, so as to ensure the positioning accuracy of the four lead-out terminals 300. At the same time, after each positioning member 400 positions the two lead-out terminals 300, the shell 100 only needs to ensure the positioning and assembly problems of the two positioning members 400, thereby reducing the relative matching positions of the lead-out terminals 300 and the shell 100.

[0114] Of course, the number of positioning members 400 may also be one, with one positioning member 400 being used to simultaneously connect the lead-out terminals 300, or the number of positioning members 400 may be four, with each positioning member 400 being connected to one lead-out terminal 300. In other embodiments of the present application, the number of lead-out terminals 300 may also be five, six, or other numbers, with one positioning member 400 being used to connect multiple lead-out terminals 300 on the same side, or each positioning member 400 corresponding to one lead-out terminal 300, or one positioning member 400 being used to connect all lead-out terminals 300.

[0115] In one embodiment, at least two lead terminals 300 are disposed on the same side of the housing 100, and each positioning member 400 is simultaneously connected to at least two lead terminals 300, or each positioning member 400 is connected to one lead terminal 300. In other words, at least two lead terminals 300 extend out of the housing 100 on the same side. For example, the at least two lead terminals 300 may be disposed on the front or rear side of the housing 100 and extend out. In this case, a single positioning member 400 may be used to connect all or some of the lead terminals 300 to achieve positioning of the lead terminals 300.

[0116] See Figures 1 to 5In one embodiment, the lead-out terminal 300 includes a connecting body 310 and a lead-out body 320 disposed on the connecting body 310. The connecting body 310 is located in the housing 100 and is electrically connected to the contact assembly 200. The lead-out body 320 extends through the housing 100. The lead-out body 320 is provided in a sheet-like shape, or in a bent shape. The connecting body 310 is the main component that connects the lead-out terminal 300 to the movable spring 212. The lead-out body 320 is the component that extends from the housing 100 through the lead-out body 320. Optionally, the lead-out body 320 and the connecting body 310 are integrally formed.

[0117] The connecting body 310 is located in the housing 100. One side of the connecting body 310 is riveted to the movable spring 212, and the other side of the connecting body 310 is connected to the lead-out body 320. The lead-out body 320 extends through the side plate 120 of the housing 100 and is connected to an external wire. Moreover, the height of the connecting body 310 extends along the third direction so that the connecting body 310 is set upright. The lead-out body 320 can be set in a sheet shape, that is, the entire height of the lead-out body 320 extends along the third direction. Of course, the lead-out body 320 can also partially extend in the third direction so that the lead-out body 320 is set in a bent shape. In this way, the lead-out body 320 extends through the housing 100 in an upright manner, and the lead-out body 320 is bent on the outside of the housing 100 to facilitate the external connection of the lead-out body 320 to the wire.

[0118] See Figure 1 In one embodiment, the relay 10 further includes a cover plate 500 , which is disposed over the housing 100 . The cover plate 500 and the housing 100 together form the outer shell of the relay 10 . The cover plate 500 serves as the upper cover of the housing 100 . After the cover plate 500 is disposed over the top of the housing 100 , the cover plate 500 is connected to the housing 100 , thereby sealing the top of the housing 100 and forming the hexahedral structure of the relay 10 , thereby ensuring the performance of the relay 10 .

[0119] In one embodiment, the housing 100 has a plurality of first clamping portions 130, and the cover plate 500 has a second clamping portion 510. After the cover plate 500 is placed on the housing 100, the cover plate 500 is clamped and connected with the first clamping portions 130 of the housing 100 via the second clamping portions 510, thereby fixing the cover plate 500 to the housing 100. The first clamping portions 130 and the second clamping portions 510 are used to secure the cover plate 500 to the housing 100, thereby facilitating assembly of the cover plate 500 and the housing 100 and reducing assembly difficulty.

[0120] In this embodiment, the first clamping portion 130 is a buckle and the second clamping portion 510 is a slot. Of course, the first clamping portion 130 can also be a buckle and the second clamping portion 510 can be a slot. In other embodiments of the present application, the housing 100 and the cover plate 500 can also be connected by riveting or other methods.

[0121] See Figures 1 to 5 In one embodiment, a positioning member 400 is disposed on at least one side of the lead-out terminal 300 along the third direction. The positioning member 400 extends along the third direction and connects to the lead-out terminal 300. Furthermore, the positioning member 400 positions the lead-out terminal 300 on at least one side in the third direction. In other words, the positioning member 400 can connect to the lead-out terminal 300 from above, below, or both, to achieve positioning of the lead-out terminal 300 and ensure accurate positioning of the lead-out terminal 300.

[0122] In this embodiment, the positioning member 400 can position the lead-out terminal 300 along the third direction, that is, the positioning member 400 is connected to the lead-out terminal 300 at the top and bottom to position the lead-out terminal 300. Of course, in other embodiments of the present application, the positioning member 400 is provided on the side of the lead-out terminal 300 that is away from the bottom plate 110 of the housing 100, that is, the positioning member 400 is connected to the lead-out terminal 300 at the top, or the positioning member 400 is provided between the lead-out terminal 300 and the bottom plate 110 of the housing 100, that is, the positioning member 400 is connected to the lead-out terminal 300 at the bottom to achieve positioning of the lead-out terminal 300.

[0123] It is worth noting that the positioning of the positioning member 400 above and below the lead-out end 300 is roughly the same as the structure and principle of the positioning member 400 above or below the lead-out end 300. The following text will only use the positioning of the positioning member 400 above and below the lead-out end 300 as an example to illustrate.

[0124] See Figures 2 to 5 、 Figures 7 to 9 In one embodiment, the positioning member 400 includes two positioning frames 410 . The two positioning frames 410 are arranged on both sides of the lead-out terminal 300 along the third direction and are used to position and connect the lead-out terminal 300 . Figure 7 for Figure 2 The schematic diagram of the positioning member 400 in the relay 10 shown in one viewing angle is shown in FIG. Figure 8 for Figure 7 The schematic diagram of the positioning member 400 shown in another perspective, Figure 9 for Figure 7 An exploded schematic diagram of the positioning member 400 is shown.

[0125] The two positioning frames 410 are arranged along the third direction, one positioning frame 410 is located above, and the other positioning frame 410 is located below. The two positioning frames 410 are arranged in a symmetrical manner up and down, and the two positioning frames 410 are connected. The lower positioning frame 410 is set on the bottom plate 110 of the shell 100, and the upper positioning frame 410 is installed on the side plate 120 of the shell 100. After the lead-out end 300 is connected to the two positioning frames 410, the positioning frame 410 can limit the lead-out end 300 along the first direction and the second direction. At the same time, because the lead-out end 300 is located between the two positioning frames 410, the positioning frame 410 can also position the lead-out end 300 along the third direction.

[0126] In this way, after the two positioning frames 410 are respectively connected to the lead-out terminal 300 on both sides of the third direction, the lead-out terminal 300 can be positioned in the third direction, the first direction and the second direction, so that the lead-out terminal 300 is reliably fixed to the shell 100, thereby improving the positioning accuracy and positioning efficiency of the lead-out terminal 300, thereby improving the assembly accuracy of the lead-out terminal 300, so as to ensure the reliability of the contact gap, thereby ensuring the performance of the relay 10.

[0127] See Figure 3 、 Figures 7 to 9 In one embodiment, the two positioning brackets 410 are provided as separate components. In other words, the positioning member 400 is designed as a separate component to facilitate assembly of the positioning brackets 410 and the lead terminal 300. The assembly of the positioning member 400, the lead terminal 300, and the housing 100 is generally not limited. Two possible assembly methods are described below, but these are not limited to the following and may be other methods.

[0128] One assembly method is as follows: During assembly, the lead terminal 300 is inserted into the lower positioning frame 410 and connected to the dynamic spring 212. Then, the upper positioning frame 410 is mounted on the lower positioning frame 410. Subsequently, the two positioning frames 410, the dynamic contact 210, the static contact 220, and the lead terminal 300 are installed in the housing 100, and the upper positioning frame 410 is connected to the side plate 120 of the housing 100. In this way, the positioning member 400, the lead terminal 300, and the housing 100 are assembled.

[0129] Another assembly method is as follows: during assembly, the lower positioning frame 410 is mounted on the bottom plate 110 of the housing 100, and then the lead terminal 300 is inserted into the lower positioning frame 410 and connected to the movable spring 212. Then, the upper positioning frame 410 is mounted on the lower positioning frame 410 and connected to the side plate 120 of the housing 100. In this way, the positioning member 400, the lead terminal 300 and the housing 100 are assembled.

[0130] See Figures 2 to 5In one embodiment, the positioning frame 410 and the lead terminal 300 are assembled along the third direction. This allows the positioning frame 410 to clamp and position the lead terminal 300 near the movable contact 211, improving the positioning accuracy of the positioning frame 410 on the lead terminal 300 and ensuring the positioning effect of the lead terminal 300. Furthermore, the positioning frame 410 can also be automatically inserted into the lead terminal 300, facilitating assembly of the lead terminal 300 and the positioning frame 410, thereby improving assembly efficiency.

[0131] Of course, in other embodiments of the present application, the two positioning frames 410 are integrally formed. In other words, the two positioning frames 410 can also be integrally formed. During assembly, the positioning member 400 is directly installed as a whole into the housing 100, and then the lead-out terminal 300 is partially inserted into the positioning member 400 from the side. This also allows the lead-out terminal 300 to be assembled with the positioning member 400, and the lead-out terminal 300 can also be reliably positioned by the positioning member 400.

[0132] Optionally, there are slight differences in the structures of the two positioning frames 410 in the positioning member 400. Here, only the structure of one of the positioning frames 410 is used as an example for description, and the differences between the two are explained. Moreover, the structures and principles of the two positioning frames 410 in the positioning member 400 are essentially the same whether they are integrated structures or split designs. Here, only the solution of the two positioning frames 410 being split designs is used as an example for description. Moreover, in the present application, the positioning member 400 simultaneously positions the two lead-out terminals 300, and the structures for the positioning member 400 to achieve positioning cooperation with the two lead-out terminals 300 are essentially the same. Here, only the positioning cooperation between the positioning member 400 and one lead-out terminal 300 is explained.

[0133] See Figures 2 to 12 In one embodiment, the positioning frame 410 includes a positioning body 411 and a mounting body 412 disposed on the positioning body 411. The mounting body 412 extends toward the other positioning frame 410 and is connected to the mounting body 412 of the other positioning frame 410. The lead-out terminal 300 is positioned and connected to the positioning body 411 and / or the mounting body 412. Figure 10 for Figure 2 The schematic diagram of the relay 10 shown in FIG. 1 is shown in FIG. 1 , wherein the upper positioning frame 410 is removed. Figure 11 for Figure 7 The schematic diagram of the upper positioning frame 410 of the positioning member 400 is shown. Figure 12 for Figure 7 A schematic diagram of the positioning frame 410 at the lower part of the positioning member 400 is shown.

[0134] The mounting body 412 extends along the third direction, and the positioning body 411 is located in a horizontal plane formed by the first and second directions. The mounting body 412 is disposed on a surface of the positioning body 411. When the positioning frame 410 is assembled with the lead terminal 300, the positioning body 411 and the lead terminal 300 are arranged along the third direction, while the mounting body 412 and the lead terminal 300 are arranged along the first direction. Taking the positioning frame 410 shown above as an example, the positioning body 411 is located above the lead terminal 300, and the mounting body 412 is located to the left or right of the lead terminal 300.

[0135] When the lead-out terminal 300 cooperates with the upper positioning frame 410 and the lower positioning frame 410, the upper and lower sides of the lead-out terminal 300 are respectively positioned and connected with the positioning body 411. At this time, the upper and lower positioning bodies 411 are relative to the upper and lower end covers of the lead-out terminal 300, and can limit the lead-out terminal 300 in the third direction. At the same time, after the lead-out terminal 300 is connected to the positioning body 411, the positioning body 411 can also position the lead-out terminal 300 in the first direction and the second direction to improve the accuracy of the positioning of the lead-out terminal 300.

[0136] Moreover, after the lead-out terminal 300 is connected to the mounting body 412, the mounting body 412 can limit the position of the lead-out terminal 300 in the first direction and the second direction, further improving the positioning accuracy of the lead-out terminal 300. It is understandable that in some embodiments, the lead-out terminal 300 can also be positioned only by the mounting body 412, that is, the lead-out terminal 300 and the side wall of the mounting body 412 have an interference fit to achieve the position limitation of the lead-out terminal 300 in the first direction and the second direction; of course, the lead-out terminal 300 can also be positioned only by the positioning body 411, with the upper and lower sides of the lead-out terminal 300 respectively connected to the positioning body 411 to limit the position of the lead-out terminal 300 in the third direction, the first direction, and the second direction.

[0137] Thus, the relay 10 of the present application uses the positioning member 400 to simultaneously position the lead terminal 300 in multiple directions. The lead terminal 300 is connected to the positioning body 411 and the mounting body 412, respectively. The positioning body 411 and the mounting body 412 position the lead terminal 300 in the third direction, the first direction, and the second direction, thereby reliably supporting the lead terminal 300, improving the positioning accuracy and efficiency of the lead terminal 300, and thus improving the reliability of the contact gap.

[0138] In one embodiment, at least a portion of the edge of the positioning body 411 protrudes from the outer circumference of the mounting body 412. In other words, at least a portion of the edge of the positioning body 411 protrudes from the sidewall of the mounting body 412, facilitating connection between the lead-out terminal 300 and the positioning body 411, so that the positioning body 411 can position the lead-out terminal 300 in the first direction and the second direction, thereby improving the accuracy of positioning the lead-out terminal 300.

[0139] In one embodiment, positioning body 411 is a mounting plate, and mounting body 412 is a mounting column. That is, positioning body 411 is plate-shaped, and mounting body 412 is column-shaped. Optionally, positioning body 411 and mounting body 412 are integrally formed to enhance the structural strength of positioning frame 410. Of course, in other embodiments of the present application, positioning body 411 and mounting body 412 may also have other shapes, as long as they can reliably position lead-out terminal 300.

[0140] See Figures 2 to 5 、 Figures 7 to 16 In one embodiment, the positioning body 411 has a first positioning portion 4111 , and the edge of the lead-out end 300 facing the positioning body 411 has a second positioning portion 330 , and the second positioning portion 330 is installed on the first positioning portion 4111 along the third direction. Figure 13 for Figure 3 The cross-sectional view of the relay 10 shown along the AA direction, Figure 14 for Figure 3 The cross-sectional view of the relay 10 along the BB direction is shown. Figure 15 for Figure 8 The top view of the positioning member 400 is shown, Figure 16 for Figure 15 The positioning member 400 is shown in a cross-sectional view along the CC direction.

[0141] A first positioning portion 4111 is provided on the surface of the positioning body 411 facing the lead terminal 300, and second positioning portions 330 are provided on the upper and lower sides of the lead terminal 300. When the lead terminal 300 and the positioning frame 410 are assembled along the third direction, the second positioning portion 330 of the lead terminal 300 can be mounted to the first positioning portion 4111 of the positioning body 411 in the positioning frame 410 along the third direction. The cooperation between the second positioning portion 330 and the first positioning portion 4111 achieves the positioning of the lead terminal 300, thereby positioning the lead terminal 300 in the third direction, the first direction, and the second direction.

[0142] In this embodiment, the first positioning portion 4111 is a positioning groove, and the second positioning portion 330 is a positioning protrusion. Specifically, positioning protrusions are provided on the upper and lower sides of the lead terminal 300, and a positioning groove is provided on the positioning body 411. When the lead terminal 300 is assembled with the positioning frame 410, the positioning protrusions of the lead terminal 300 can be inserted into the positioning grooves of the positioning frame 410 along the third direction, thereby positioning the lead terminal 300. Of course, in other embodiments of the present application, the first positioning portion 4111 can also be a positioning protrusion, and the second positioning portion 330 can be a positioning groove.

[0143] See Figures 2 to 5 、 Figures 7 to 16In one embodiment, there are multiple second positioning portions 330, each of which is spaced apart along the first direction. The number of first positioning portions 4111 is equal to the number of second positioning portions 330 and is correspondingly arranged. Thus, through the cooperation of the multiple first positioning portions 4111 and the multiple second positioning portions 330, the positioning frame 410 and the lead terminal 300 are positioned at multiple points in the first direction, thereby improving the positioning accuracy and stability of the lead terminal 300.

[0144] In this embodiment, there are two second positioning portions 330, which are spaced apart along the first direction on the lead-out terminal 300. The number of first positioning portions 4111 on the positioning body 411 corresponds to the number of second positioning portions 330. In this way, the positioning body 411 can position the lead-out terminal 300 through the cooperation of the two first positioning portions 4111 and the two second positioning portions 330, thereby improving the positioning accuracy of the lead-out terminal 300. Figures 9 to 12 It is worth noting that one positioning frame 410 of the present application is connected to two lead-out terminals 300 at the same time, so four first positioning portions 4111 are provided on one positioning frame 410 .

[0145] Optionally, the two second positioning portions 330 have the same or different sizes along the first direction. Of course, in other embodiments of the present application, the number of the second positioning portions 330 can also be one or other numbers, and the first positioning portion 4111 is adapted to the second positioning portion 330 .

[0146] See Figures 2 to 5 、 Figures 7 to 16 In one embodiment, the second positioning portion 330 at least partially overlaps the static contact 221 in the third direction. Thus, the positioning frame 410 can support the lead terminal 300 in the area where the movable contact 211 and the static contact 221 contact each other, reducing the shaking of the lead terminal 300 when the movable contact 211 and the static contact 221 are closed or opened, thereby improving the positioning accuracy of the lead terminal 300 by the positioning frame 410.

[0147] See Figures 2 to 5 、 Figures 7 to 16 In one embodiment, the second positioning portion 330 is disposed near the side panel 120. Thus, the connection between the positioning frame 410 and the lead terminal 300 can be close to the side panel 120, thereby improving the positioning accuracy of the lead terminal 300 near the side panel 120, improving the matching accuracy between the lead terminal 300 and the side panel 120, and reducing the assembly stress caused by dimensional deviation. At the same time, it can also ensure that the positional accuracy of the lead terminal 300 and the external external connection parts (such as copper strips, welding, riveting, and other electrical connections) are relatively accurate, reducing the assembly stress caused by installation position deviation.

[0148] Optionally, there are at least two second positioning portions 330, one of which at least partially overlaps the static contact 221 in the third direction, and the other second positioning portion 330 is disposed near the side plate 120. Of course, in other embodiments of the present application, there may be only one second positioning portion 330, the second positioning portion 330 at least partially overlaps the static contact 221 in the third direction, or the second positioning portion 330 is disposed near the side plate 120.

[0149] See Figures 2 to 5 、 Figures 7 to 16 In one embodiment, the mounting body 412 has a third positioning portion 4121, and the surface of the lead terminal 300 facing the mounting body 412 has a fourth positioning portion 340. The fourth positioning portion 340 is mounted in the third positioning portion 4121 along the third direction. The third positioning portion 4121 is disposed on a sidewall of the mounting body 412 and faces the side of the lead terminal 300. The fourth positioning portion 340 is disposed on the surface of the lead terminal 300 opposite the mounting body 412 and corresponds to the third positioning portion 4121.

[0150] When the lead terminal 300 is assembled with the positioning frame 410 along the third direction, and the lead terminal 300 is inserted into the positioning frame 410 along the third direction, the third positioning portion 4121 and the fourth positioning portion 340 are positioned opposite each other, and the lead terminal 300 can move along the third positioning portion 4121 via the fourth positioning portion 340, thereby guiding and limiting the assembly of the lead terminal 300 with the positioning frame 410. After the lead terminal 300 is connected to the positioning body 411, the third positioning portion 4121 and the fourth positioning portion 340 are positioned and matched, and the lead terminal 300 is positioned by the third positioning portion 4121 and the fourth positioning portion 340, thereby positioning the lead terminal 300 in the first direction and the second direction.

[0151] In this embodiment, the third positioning portion 4121 is a positioning groove, and the fourth positioning portion 340 is a positioning protrusion. Specifically, a positioning protrusion is provided on the side of the lead terminal 300, and a positioning groove is provided on the mounting body 412. When the lead terminal 300 and the positioning frame 410 are assembled along the third direction, the positioning protrusion of the lead terminal 300 can be inserted into the positioning groove of the positioning frame 410 along the third direction and can slide along the positioning groove to achieve positioning of the lead terminal 300. Of course, in other embodiments of the present application, the third positioning portion 4121 can also be a positioning protrusion, and the fourth positioning portion 340 can be a positioning groove. Optionally, the third positioning portion 4121 and the fourth positioning portion 340 form an interference fit.

[0152] See Figures 2 to 5 、 Figures 7 to 16In one embodiment, the positioning frame 410 further includes a limiting body 413 disposed at an edge of the mounting body 412. The limiting body 413 is disposed opposite the mounting body 412 and forms a receiving groove with the mounting body 412 for receiving the lead-out terminal 300. The limiting body 413 is disposed at an edge of the positioning body 411 and extends along the third direction. Furthermore, a certain distance exists between the limiting body 413 and the mounting body 412 in the second direction.

[0153] Thus, a certain distance exists between the limiting body 413 and the mounting body 412 to form a receiving groove. After the lead terminal 300 and the positioning frame 410 are assembled along the third direction, the lead terminal 300 is partially located in the receiving groove. The receiving groove can further limit the position of the lead terminal 300 in the second direction, so that the limiting body 413 can further support the lead terminal 300 in the contact direction, thereby improving the positioning accuracy of the lead terminal 300.

[0154] Optionally, both positioning frames 410 are provided with a limiting body 413. Of course, the limiting body 413 may also be provided on only one of the positioning frames 410. In this embodiment, the limiting body 413 is provided on the upper positioning frame 410, while the lower positioning frame 410 is not provided with a limiting body 413. Optionally, the limiting body 413 is provided in a plate-like shape and is integrally formed with the positioning body 411 to enhance structural strength.

[0155] See Figures 2 to 16 In one embodiment, the positioning frame 410 further has a first guide portion 414, which is arranged on the edge of the mounting body 412 along a third direction. The surface of the shell 100 corresponding to the first guide portion 414 has a second guide portion 140, and the first guide portion 414 cooperates with the second guide portion 140 to guide along the third direction to guide and limit the positioning frame 410 when installed on the shell 100.

[0156] The first guide portion 414 is provided on the edge of the mounting body 412 along the third direction. Furthermore, the first guide portion 414 can also be provided on the side wall of the limiting body 413. The inner wall of the side plate 120 of the shell 100 has a second guide portion 140 extending along the third direction. When the positioning frame 410 is assembled with the shell 100 along the third direction, the first guide portion 414 of the positioning frame 410 is aligned with the second guide portion 140 of the shell 100, and the first guide portion 414 and the second guide portion 140 are guided and matched. When the positioning frame 410 is installed in the shell 100 along the third direction, the guiding cooperation between the first guide portion 414 and the second guide portion 140 can limit the positioning frame 410, so that the positioning frame 410 can be accurately installed in the shell 100.

[0157] In this embodiment, the first guide portion 414 is a guide protrusion, and the second guide portion 140 is a guide groove. That is, a guide protrusion is provided on the side of the positioning frame 410, and a guide groove is provided on the inner wall of the side plate 120 of the shell 100. When the positioning frame 410 is assembled with the shell 100, the guide protrusion of the positioning frame 410 can be inserted into the guide groove of the shell 100 and can slide along the guide groove to achieve the guide limit of the positioning frame 410. Of course, in other embodiments of the present application, the first guide portion 414 can also be a guide groove, and the second guide portion 140 can be a guide protrusion. In one embodiment, the dimension of the second guide portion 140 along the third direction is the same as the dimension of the side plate 120 along the third direction. In this way, one second guide portion 140 can limit the two brackets at the same time.

[0158] See Figures 2 to 16 In one embodiment, the positioning frame 410 further has a first matching portion 415, which is arranged on the edge of the mounting body 412 along a third direction. The surface of the shell 100 corresponding to the first matching portion 415 has a second matching portion 150, and the first matching portion 415 and the second matching portion 150 are matched and connected along the third direction, wherein the first matching portion 415 and the second matching portion 150 are riveted or adhesively connected.

[0159] The first mating portion 415 is provided on the edge of the mounting body 412 along the third direction. Furthermore, the first mating portion 415 can also be provided on the side wall of the limiting body 413. The inner wall of the side plate 120 of the housing 100 has a second mating portion 150 extending along the third direction. When the positioning frame 410 is assembled with the housing 100 along the third direction, the first guide portion 414 of the positioning frame 410 is aligned with the second guide portion 140 of the housing 100 and guided to mate. At this time, the first mating portion 415 of the positioning frame 410 also corresponds to the second mating portion 150 of the housing 100. After the positioning frame 410 is installed in place on the housing 100, the first mating portion 415 can be mated and connected with the second mating portion 150 along the third direction. By fixing the first mating portion 415 to the second mating portion 150, a fixed connection between the positioning frame 410 and the housing 100 can be achieved.

[0160] Optionally, the first mating portion 415 is a mating protrusion, and the second mating portion 150 is a mating groove. That is, a mating protrusion can be provided on the side of the positioning frame 410, and a mating groove can be provided on the inner wall of the side plate 120 of the housing 100. After the positioning frame 410 and the housing 100 are assembled, the mating protrusion can be located in the mating groove. At this time, the mating groove is alternately injected to bond the mating protrusion to the inner wall of the mating groove, thereby achieving adhesive fixation of the positioning frame 410 to the housing 100. Of course, in other embodiments of the present application, the first mating portion 415 can also be a mating protrusion, and the second mating portion 150 can be a mating groove.

[0161] Optionally, both the first mating portion 415 and the second mating portion 150 are hollow fixing columns, and the first mating portion 415 and the second mating portion 150 can be fixed by threading or riveting to achieve a fixed connection between the positioning frame 410 and the housing 100. Optionally, the first mating portion 415 can be provided only on the upper positioning frame 410, or on both the upper and lower positioning frames 410, or only on the lower positioning frame 410. Of course, in other embodiments, the bonding or riveting locations can also be set at other locations, as long as the positioning frame 410 and the housing 100 can be fixedly installed.

[0162] See Figures 2 to 5 、 Figures 7 to 16 In one embodiment, one of the two positioning frames 410 has a first positioning protrusion 416, and the other has a first positioning groove 417 opposite to the first positioning protrusion 416. The first positioning protrusion 416 and the first positioning groove 417 cooperate to position the two positioning frames 410. In this embodiment, the upper positioning frame 410 has the first positioning protrusion 416, and the lower positioning frame 410 has the first positioning groove 417. When the upper positioning frame 410 is assembled with the lower positioning frame 410, the first positioning protrusion 416 can be inserted into the first positioning groove 417 to achieve the assembly of the two positioning frames 410.

[0163] Of course, in other embodiments of the present application, the lower positioning frame 410 may also have a first positioning protrusion 416, and the upper positioning frame 410 may have a first positioning groove 417. Optionally, the end of the first positioning protrusion 416 is pointed, and the end of the first positioning groove 417 is open, so as to facilitate the positioning and matching of the first positioning protrusion 416 and the first positioning groove 417. Optionally, the first positioning protrusion 416 and the first positioning groove 417 are located on the mounting body 412 of the positioning frame 410.

[0164] See Figures 2 to 16 In one embodiment, the bottom wall of the housing 100 has a second positioning protrusion 160, and a positioning frame 410 has a second positioning groove 418 on the side facing the housing 100, which is opposite to the second positioning protrusion 160. The second positioning protrusion 160 and the second positioning groove 418 are positioned and matched to position the positioning frame 410 and the housing 100. In this embodiment, the second positioning protrusion 160 is provided on the bottom plate 110 of the housing 100, and the positioning frame 410 below has a second positioning groove 418. When the positioning frame 410 is assembled with the housing 100, the second positioning protrusion 160 can be inserted into the second positioning groove 418 to achieve assembly of the positioning frame 410 with the housing 100.

[0165] Of course, in other embodiments of the present application, the lower positioning frame 410 may also have a second positioning protrusion 160, and the bottom plate 110 of the housing 100 may have a second positioning groove 418. Optionally, the end of the second positioning protrusion 160 is pointed, and the end of the second positioning groove 418 is open, so as to facilitate the positioning and matching of the second positioning protrusion 160 and the second positioning groove 418. Optionally, the second positioning protrusion 160 or the second positioning groove 418 is located on the positioning body 411 of the positioning frame 410.

[0166] The relay 10 of the present application uses a positioning member 400 to position the lead-out terminal 300. In this way, after the lead-out terminal 300 is positioned by the positioning member 400, the reliability of the positioning of the lead-out terminal 300 can be improved, so that the lead-out terminal 300 is accurately positioned relative to the housing 100, thereby improving the assembly accuracy of the lead-out terminal 300, improving the reliability of the contact gap, and further ensuring the performance of the relay 10.

[0167] Furthermore, after the lead terminal 300 is positioned using the positioning member 400, the lead terminal 300 extends only through the mounting position 121 of the side panel 120, eliminating the need for the inner wall of the mounting position 121 to position the lead terminal 300. Thus, even if the mold release chamfer at the mounting position 121 is large, it will not affect the positioning of the lead terminal 300, thereby ensuring the assembly accuracy of the lead terminal 300 and, in turn, ensuring a reliable gap between the moving contact 211 and the static contact 221. Furthermore, during the molding of the housing 100, there is no need to control a large number of dimensions, which reduces the molding difficulty of the housing 100 and facilitates the molding of the housing 100.

[0168] At the same time, the positioning member 400 can position and support the lead terminal 300 in the contact direction between the dynamic contact 210 and the static contact 220. When the reaction force generated when the dynamic contact 210 and the static contact 220 are closed or disconnected acts on the lead terminal 300, the positioning member 400 and the positioning member 400 by the housing 100 can provide sufficient support for the positioning member 400, and thus the positioning member 400 can provide sufficient support for the lead terminal 300. In this way, even if the mounting position 121 on the side panel 120 is deep, the side panel 120 does not need to support the lead terminal 300, thus preventing deformation of the side panel 120 and ensuring the structural strength of the housing 100. In addition, the positioning member 400 can provide positioning accuracy and reliable support for the lead terminal 300 in the contact direction, thereby achieving accurate positioning of the lead terminal 300 and ensuring the reliability of the contact gap.

[0169] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0170] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
