Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to relays. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current, thus playing roles in automatic adjustment, safety protection, and circuit switching. It is used in household appliances, automobiles, industrial control, power systems, and communication devices.

[0003] A high-voltage DC relay is a type of relay that includes a coil, a moving iron core, a stationary iron core, a push rod, a main contact group, and an auxiliary contact group. When the coil is energized, the moving iron core moves relative to the stationary iron core, driving the push rod. This movement of the push rod connects or disconnects one of the main contact group or the auxiliary contact group. Since the auxiliary contact group is connected to the circuitry of electronic components, the connection or disconnection of the auxiliary contact group can control the continuity of the circuitry in the electronic components. Simultaneously, when the main contact group is closed, the auxiliary contact group closes or opens; conversely, when the main contact group is open, the auxiliary contact group opens or closes accordingly. The continuity of the main contact group can be monitored through the auxiliary contact group.

[0004] However, when the auxiliary contact group in the relay is connected to the power supply equipment, it needs to be connected to the power supply equipment through multiple lead-out structures. The messy wiring of the lead-out structures will occupy a lot of space in the relay. Utility Model Content

[0005] Therefore, it is necessary to provide a relay that solves the problem that when the auxiliary contact group in the relay is connected to the power supply equipment, it needs to be connected to the power supply equipment through multiple lead-out structures, resulting in messy lead-out structure wiring and occupying a large space in the relay.

[0067] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0068] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0069] 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.

[0070] 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.

[0071] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0072] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown. An embodiment of this application provides a relay 10, including an auxiliary contact assembly 1, a conversion module 21, and a first plug-in terminal 3. The auxiliary contact assembly 1 includes an auxiliary contact group 11 and an auxiliary lead-out assembly 12. The auxiliary lead-out assembly 12 includes multiple auxiliary lead-out units 121; one end of each auxiliary lead-out unit 121 is electrically connected to the auxiliary contact group 11. The conversion module 21 is electrically connected to the other end of each auxiliary lead-out unit 121. One end of the first plug-in terminal 3 is connected to the conversion module 21, and the other end is used to connect to a connector. The other ends of each auxiliary lead-out unit 121 are all electrically connected to the same first plug-in terminal 3 through the conversion module 21.

[0073] It should be noted that the relay 10 in this application also includes a coil 7, a moving iron core 13, a stationary iron core 9, and a push rod 14. When the coil 7 is energized, the moving iron core 13 moves relative to the stationary iron core 9, causing the push rod 14 to move. The movement of the push rod 14 causes the auxiliary contact group 11 to connect or disconnect. Since the auxiliary contact group 11 is connected to the circuit of the electronic components, the connection or disconnection of the auxiliary contact group 11 in the relay 10 can control the on / off state of the circuit in the electronic components.

[0074] Since there are multiple auxiliary lead-out units 121 in this application, if the multiple auxiliary lead-out units 121 in the relay 10 are directly connected to the first plug-in terminal 3, it is necessary to connect the multiple auxiliary lead-out units 121 to the first plug-in terminal 3 through wires, or it is necessary to extend the multiple auxiliary lead-out units 121, resulting in messy wiring of the multiple auxiliary lead-out units 121. Furthermore, since one end of the multiple auxiliary lead-out units 121 is electrically connected to the auxiliary contact group 11, and the conversion module 21 is electrically connected to the other end of the multiple auxiliary lead-out units 121, and one end of the first plug-in terminal 3 is connected to the conversion module 21, and the other end is used to connect to the connector, the other end of the multiple auxiliary lead-out units 121 can be electrically connected to the same first plug-in terminal 3 through the conversion module 21, thereby avoiding messy wiring of the auxiliary lead-out assembly 12 and reducing the space occupied by the auxiliary lead-out assembly 12, thereby saving space of the relay 10.

[0075] It is understandable that, since this application can realize the connection between multiple auxiliary lead-out units 121 and a first plug-in terminal 3 through the conversion module 21, the complexity and confusion of the wiring connection during the connection of multiple auxiliary lead-out units 121 and the first plug-in terminal 3 can be avoided, thereby further optimizing the wiring connection and layout of the relay 10, and at the same time facilitating the installation and maintenance of the installers.

[0076] In some embodiments, there are multiple auxiliary contact components 1, and the other end of all auxiliary lead-out units 121 in the multiple auxiliary contact components 1 are electrically connected to the same first plug-in terminal 3 through a conversion module 21.

[0077] Thus, since there are multiple auxiliary contact components 1, and as described above, one auxiliary lead-out component 12 includes multiple auxiliary lead-out units 121, resulting in a greater number of auxiliary lead-out units 121 in the multiple auxiliary contact components 1. If the multiple auxiliary lead-out units 121 in the multiple auxiliary contact components 1 are directly connected to the first plug-in terminal 3, more wires are needed to connect the multiple auxiliary lead-out units 121 to the first plug-in terminal 3, or the multiple auxiliary lead-out units 121 need to be extended, resulting in more messy wiring of the multiple auxiliary lead-out units 121.

[0078] Furthermore, since the other end of all the auxiliary lead-out units 121 in the multiple auxiliary contact assemblies 1 are electrically connected to the same first plug terminal 3 through the conversion module 21, and the other end of the first plug terminal 3 is used to connect to the connector, the other end of the multiple auxiliary lead-out units 121 in the multiple auxiliary contact assemblies 1 can be electrically connected to the same first plug terminal 3 through the conversion module 21, thereby further avoiding the messy wiring of the multiple auxiliary contact assemblies 1 and further reducing the space occupied by the multiple auxiliary contact assemblies 1, thereby saving space for the relay 10.

[0079] In some embodiments, the relay 10 includes at least one relay body 4, and the relay body 4 includes at least one auxiliary contact assembly 1.

[0080] It should be noted that the relay 10 of this application includes at least one relay body 4. If the number of relay bodies 4 is one, the relay 10 of this application is an independent relay 10. If the number of relay bodies 4 is multiple, the relay 10 of this application is a combined relay. A combined relay is an electrical switching device capable of multi-channel control, composed of multiple relay bodies 4, and can simultaneously control multiple circuits. The relay body 4 serves as the working body of the combined relay, and consists of a drive mechanism, an actuating mechanism, and a contact mechanism. The drive mechanism closes or opens the contacts, thereby controlling the circuit's on / off state. It should be noted that individual relay bodies 4 do not have a housing; multiple relay bodies 4 share a housing assembly 5, thus forming a combined relay.

[0081] A twin relay is a device consisting of two independent relay bodies 4, which perform their functions through control signals. Each relay body 4 has its own independent control circuit and contact mechanism. In the circuit, when the control signal is energized, both relay bodies 4 will operate, realizing their functions. Based on the above description, the twin relay also belongs to the combined relay of this application. Here, the specific number of relay bodies 4 in the combined relay will not be elaborated.

[0082] It is understood that the auxiliary contact component 1, the conversion module 21 and the first plug-in terminal 3 in this application can be applied to the independent relay 10 or to the combined relay. Here, this application does not limit the specific type of relay 10.

[0083] Thus, since the relay body 4 includes at least one auxiliary contact assembly 1, and the other end of all auxiliary lead-out units 121 in at least one auxiliary contact assembly 1 is electrically connected to the same first plug-in terminal 3 through the conversion module 21, and the other end of the first plug-in terminal 3 is used to connect to the connector, the other ends of multiple auxiliary lead-out units 121 in at least one auxiliary contact assembly 1 can be electrically connected to the same first plug-in terminal 3 through the conversion module 21, thereby further avoiding the wiring disorder of at least one auxiliary contact assembly 1, and further reducing the space occupied by at least one auxiliary contact assembly 1, thereby saving the space occupied by the relay body 4.

[0084] In some embodiments, see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the relay 10 also includes a housing assembly 5, which includes a first housing 51 and a second housing 52 that form a receiving cavity; the first housing 51 includes a first housing wall 511, the second housing 52 includes a second housing wall 521, the first housing wall 511 and the second housing wall 521 are arranged opposite to each other along a first direction, the auxiliary contact assembly 1 is disposed on the side of the first housing wall 511 facing the second housing wall 521, and the conversion module 21 is disposed on the side of the auxiliary contact assembly 1 facing the second housing wall 521.

[0085] It should be noted that the housing assembly 5, as the frame structure of the relay 10, serves two purposes: firstly, it supports and fixes the switching module 21 and other structures within the relay 10, thereby ensuring the normal operation of the relay 10; secondly, it protects the switching module 21 and other structures from external damage, further ensuring the normal operation of the relay 10.

[0086] It should be added that the first direction is Figure 8 , Figure 9 and Figure 10 The X direction in the equation.

[0087] Thus, the auxiliary contact assembly 1, the conversion module 21, and the first plug-in terminal 3 can be protected by the first housing 51 and the second housing 52 to prevent damage from the external environment. Since the auxiliary contact assembly 1 is located on the side of the first housing wall 511 facing the second housing wall 521, and the conversion module 21 is located on the side of the auxiliary contact assembly 1 facing the second housing wall 521, on the one hand, the position of the conversion module 21 can be prevented from affecting the normal operation of the auxiliary contact assembly 1 during the connection process. On the other hand, the second housing wall 521 can support and fix the conversion module 21, thereby improving the stability of the conversion module 21 and consequently improving the stability of the relay 10.

[0088] In some embodiments, see Figure 2 and Figure 3 As shown, the auxiliary lead-out unit 121 includes a first connecting segment 1211 and a second connecting segment 1212 that are connected to each other. The end of the second connecting segment 1212 away from the first connecting segment 1211 is electrically connected to the conversion module 21. The end of the first connecting segment 1211 away from the second connecting segment 1212 is connected to the auxiliary contact group 11. The first connecting segment 1211 extends along a second direction, and the second connecting segment 1212 extends along a first direction. The first direction and the second direction intersect.

[0089] It should be noted that the first direction is Figure 2 and Figure 3 The X direction in the middle, the second direction is Figure 2 and Figure 3 in the Y direction.

[0090] Thus, in the process of connecting the auxiliary contact group 11 and the conversion module 21 through the first connecting segment 1211 and the second connecting segment 1212 respectively, the direction of connection between the auxiliary lead-out unit 121 and the auxiliary contact group 11 and the conversion module 21 can be changed by using the first connecting segment 1211 and the second connecting segment 1212 with different extension directions. This allows the connection between the auxiliary contact group 11 and the conversion module 21 to be realized in different positions according to actual usage requirements, thereby further optimizing the arrangement of internal components of the relay 10 and thus optimizing the spatial structure of the relay 10.

[0091] In some embodiments, in the same auxiliary lead-out unit 121, the first connecting segment 1211 and the second connecting segment 1212 are an integral structure.

[0092] Thus, on the one hand, the integrated structure makes the connection between the first connecting segment 1211 and the second connecting segment 1212 more robust. Compared with a non-integrated structure, it reduces the possibility of loosening and breakage due to too many connection points, and can better withstand external forces and various stresses, thereby ensuring the structural integrity and reliability of the auxiliary lead-out unit 121 during use. On the other hand, the integrated structure can be manufactured through a one-time molding process, such as injection molding or casting. Compared with manufacturing the first connecting segment 1211 and the second connecting segment 1212 separately and then assembling them, it reduces processing steps and assembly stages, improves production efficiency, reduces production costs, and also helps to ensure product consistency and quality stability.

[0093] In some embodiments, see Figure 2 and Figure 3 As shown, the plurality of auxiliary lead-out units 121 include a first auxiliary lead-out unit 1213 and a second auxiliary lead-out unit 1214; the first connecting segment 1211 of the first auxiliary lead-out unit 1213 is disposed on the side of the second connecting segment 1212 of the first auxiliary lead-out unit 1213 away from the second connecting segment 1212 of the second auxiliary lead-out unit 1214, and the first connecting segment 1211 of the second auxiliary lead-out unit 1214 is disposed on the side of the second connecting segment 1212 of the second auxiliary lead-out unit 1214 away from the second connecting segment 1212 of the first auxiliary lead-out unit 1213.

[0094] Thus, by placing the first connecting segments 1211 of the first auxiliary lead-out unit 1213 and the second auxiliary lead-out unit 1214 on the side of their respective second connecting segments 1212 away from each other's second connecting segments 1212, the two auxiliary lead-out units 121 can maintain a certain spatial distance, reducing interference between them and preventing crosstalk from causing circuit connection errors. Furthermore, this arrangement makes efficient use of space, avoiding the potential for congestion caused by concentrating the first connecting segments 1211 and the second connecting segments 1212 of the two auxiliary lead-out units 121 on one side. This layout allows for a more compact structure of the relay 10, better accommodating multiple auxiliary lead-out units 121 within a limited space and improving space utilization efficiency.

[0095] In some embodiments, see Figure 2 and Figure 3 As shown, the auxiliary contact group 11 includes two auxiliary stationary contacts 111 and an auxiliary moving spring 112. The first connecting section 1211 of the first auxiliary lead-out unit 1213 is connected to one of the auxiliary stationary contacts 111, and the first connecting section 1211 of the second auxiliary lead-out unit 1214 is connected to the other auxiliary stationary contact 111. The relay 10 is configured such that, in a first state, the auxiliary moving spring 112 is electrically isolated from the two auxiliary stationary contacts 111; and in a second state, the auxiliary moving spring 112 is electrically in contact with the two auxiliary stationary contacts 111.

[0096] Thus, in the first state of relay 10, the auxiliary moving spring 112 is electrically isolated from the two auxiliary stationary contacts 111. At this time, the circuit connected to the auxiliary contact group 11 is in an open state, and current cannot pass through, thereby cutting off the corresponding circuit and stopping the operation of the connected electronic components. Furthermore, when relay 10 switches to the second state, the auxiliary moving spring 112 makes electrical contact with the two auxiliary stationary contacts 111, the circuit is turned on, and current can pass through the auxiliary contact group 11, causing the connected electronic components to start working, thereby achieving precise control of the circuit's on / off state.

[0097] In some embodiments, see Figure 2 and Figure 3 As shown, the auxiliary contact group 11 also includes a first lead-out member 113 and a second lead-out member 114. The first auxiliary lead-out unit 1213 and one of the auxiliary stationary contacts 111 are electrically connected through the first lead-out member 113, and the second auxiliary lead-out unit 1214 and the other auxiliary stationary contact 111 are electrically connected through the second lead-out member 114.

[0098] Thus, the first lead-out member 113 electrically connects the first auxiliary lead-out unit 1213 to the corresponding auxiliary stationary contact 111, and the second lead-out member 114 electrically connects the second auxiliary lead-out unit 1214 to another auxiliary stationary contact 111, ensuring stable and reliable current transmission between the auxiliary lead-out unit 121 and the auxiliary stationary contact 111. The leads-out members provide good electrical contact, reduce contact resistance, and ensure normal circuit operation. Furthermore, using the first lead-out member 113 and the second lead-out member 114 makes the connection between the auxiliary lead-out unit 121 and the auxiliary stationary contact 111 more flexible. Additionally, the connection method may need to be adjusted according to different spatial layouts, wiring requirements, etc. The first lead-out member 113 and the second lead-out member 114 can be easily bent, extended, or fixed to adapt to various installation environments, making the internal assembly of the relay 10 more convenient and faster.

[0099] In some embodiments, the first auxiliary lead-out unit 1213 and the first lead-out member 113 are either an integral structure or separate structures.

[0100] Thus, the integrated structure means that there is no connection interface between the first auxiliary lead-out unit 1213 and the first lead-out member 113, thereby avoiding poor contact caused by problems such as interface loosening and oxidation, reducing connection failures caused by factors such as vibration, and ensuring the stability of current transmission. In addition, during the manufacturing process, the integrated structure does not require complex connection processes such as welding and riveting, reducing production steps, improving production efficiency, and reducing production costs.

[0101] In some embodiments, the second auxiliary lead-out unit 1214 and the second lead-out member 114 are either an integral structure or separate structures.

[0102] Thus, the integrated structure means that there is no connection interface between the second auxiliary lead-out unit 1214 and the second lead-out member 114, thereby avoiding poor contact caused by problems such as interface loosening and oxidation, reducing connection failures caused by factors such as vibration, and ensuring the stability of current transmission. In addition, during the manufacturing process, the integrated structure eliminates the need for complex connection processes such as welding and riveting, reducing production steps, improving production efficiency, and lowering production costs.

[0103] In some embodiments, see Figure 2 and Figure 3 As shown, the relay 10 also includes an insulating element 6, which is wrapped around at least part of the auxiliary lead-out assembly 12.

[0104] This prevents short circuits or leakage between the auxiliary lead-out component 12 and other conductive parts, ensuring that the current flows along a predetermined path, avoiding electrical interference between different circuits, and guaranteeing the accuracy and stability of the relay 10's operation. Furthermore, it prevents operators from accidentally coming into contact with the energized auxiliary lead-out component 12 and suffering electric shock accidents, thus ensuring personal safety. It also increases the strength of the auxiliary lead-out component 12 and reduces the risk of deformation.

[0105] In some embodiments, see Figure 2 and Figure 3 As shown, the insulating member 6 includes a first covering portion 61 and a second covering portion 62 that are interconnected; the first covering portion 61 extends along a second direction, and the second covering portion 62 extends along a first direction. The first covering portion 61 covers the first connecting segment 1211 of the first auxiliary lead-out unit 1213 and the first connecting segment 1211 of the second auxiliary lead-out unit 1214; the second covering portion of the second connecting segment 1212 of the first auxiliary lead-out unit 1213 and the second connecting segment 1212 of the second auxiliary lead-out unit 1214.

[0106] It should be noted that the first direction is Figure 2 and Figure 3 The X direction in the middle, the second direction is Figure 2 and Figure 3 in the Y direction.

[0107] Thus, the first covering part 61 and the second covering part 62 can protect the first connecting segment 1211 and the second connecting segment 1212, preventing them from being interfered with or damaged by other components. Furthermore, the first covering part 61 and the second covering part 62 can insulate the first connecting segment 1211 and the second connecting segment 1212, preventing short circuits between them and other components in the relay 10 when the internal circuit of the relay 10 is connected, thereby ensuring the normal operation of the relay 10.

[0108] In some embodiments, see Figure 2 and Figure 3 As shown, the insulating member 6 is provided with a hollow portion 63, which extends through the second covering portion 62 along the second direction.

[0109] In this way, the second connecting segment 1212 of the first auxiliary lead-out unit 1213 and the second connecting segment 1212 of the second auxiliary lead-out unit 1214 can be isolated by the cutout portion 63, thereby preventing contact between the second connecting segment 1212 of the first auxiliary lead-out unit 1213 and the second connecting segment 1212 of the second auxiliary lead-out unit 1214. Thus, even when the circuit inside the relay 10 is connected, it can further prevent short circuits between the second connecting segment 1212 of the first auxiliary lead-out unit 1213 and the second connecting segment 1212 of the second auxiliary lead-out unit 1214 and other components in the relay 10, thereby further ensuring the normal operation of the relay 10.

[0110] In some embodiments, the auxiliary lead-out unit 121 is welded to the auxiliary contact group 11.

[0111] Thus, on the one hand, since the auxiliary lead-out unit 121 and the auxiliary contact group 11 can be welded together to form a seamless connection, the strength of the connection between the auxiliary lead-out unit 121 and the auxiliary contact group 11 can be improved; on the other hand, since the welding connection does not require drilling, it can improve production efficiency, make full use of the materials of the auxiliary lead-out unit 121 and the auxiliary contact group 11, and will not damage the auxiliary lead-out unit 121 and the auxiliary contact group 11.

[0112] In some embodiments, the auxiliary lead-out unit 121 is welded to the conversion module 21.

[0113] Thus, on the one hand, since the auxiliary lead-out unit 121 and the conversion module 21 can be seamlessly connected by welding, the strength of the connection between the auxiliary lead-out unit 121 and the conversion module 21 can be improved; on the other hand, since the welding connection does not require drilling, it can improve production efficiency, make full use of the materials of the auxiliary lead-out unit 121 and the conversion module 21, and will not damage the auxiliary lead-out unit 121 and the conversion module 21.

[0114] In some embodiments, see Figure 5 As shown, the relay 10 includes a circuit board 2, and the conversion module 21 is disposed on the circuit board 2.

[0115] Circuit board 2, also known as a printed circuit board (PCB), provides the electrical connections for electronic components. It primarily provides the electrical connection paths between these components and offers physical support, acting as the "skeleton" of the electronic device, organizing the various components in an orderly manner to form a complete circuit system. The connector assembly is used to connect circuit board 2 and the connector to achieve circuit connection, thereby enabling functions such as signal transmission, power supply, and control signals.

[0116] Thus, the relay 10 includes a circuit board 2, and the conversion module 21 is disposed on the circuit board 2, which makes it easier for the circuit board 2 to be connected to other modules or devices, thereby improving the overall integration and stability of the relay 10.

[0117] In some embodiments, see Figure 4 , Figure 11 and Figure 12 As shown, the relay 10 includes a coil 7, a plurality of coil leads 71 ​​and a plurality of second plug terminals 72. The coil 7 is electrically connected to the plurality of coil leads 71. The plurality of coil leads 71 ​​and the plurality of second plug terminals 72 are correspondingly arranged. The coil leads 71 ​​and the corresponding second plug terminals 72 are electrically connected through the circuit board 2.

[0118] Thus, since the connection between multiple coil leads 71 ​​and the second plug-in terminal 72 can be realized through the circuit board 2, the complexity and confusion of the wiring connection during the connection of multiple coil leads 71 ​​and the second plug-in terminal 72 can be avoided, thereby further optimizing the wiring connection and layout of the relay 10, and at the same time facilitating the installation and maintenance by the installers.

[0119] It should be noted that the relay body 4 in this application also includes a moving iron core 13, a stationary iron core 9, a push rod 14, a main stationary contact 18, and an active contact 17. When the coil 7 is energized, the moving iron core 13 moves relative to the stationary iron core 9, driving the push rod 14 to move.

[0120] On the one hand, the movement of the push rod 14 causes the active contact 17 to contact the main stationary contact 18. At this time, the active contact 17, the main stationary contact 18 and the circuit of the high-voltage electrical equipment are connected. Since the current in the coil 7 is a low-voltage current, the on and off of the high-voltage current can be controlled by the low-voltage current.

[0121] On the other hand, the movement of the push rod 14 causes the auxiliary contact group 11 to connect or disconnect. Since the auxiliary contact group 11 is connected to the circuit of the electronic components, and the current connected to the electronic components by the auxiliary contact group 11 is a different low-voltage current from the coil 7, the on / off state of the other low-voltage current can be controlled by the low-voltage current in the coil 7.

[0122] Furthermore, it should be noted that the first plug-in terminal 3 and the second plug-in terminal 72 in this application are formed as a plug-in terminal assembly, wherein the first plug-in terminal 3 is used to connect to the conversion module 21 to realize the connection with multiple auxiliary lead-out units 121; the second plug-in terminal 72 is used to connect to the circuit board 2 to realize the connection with multiple coil lead-out parts 71.

[0123] Optionally, see Figure 4 , Figure 11 and Figure 12 As shown, the terminal assembly also includes a third terminal 82. The relay 10 also includes a thermistor 8 and a thermistor lead 81. The thermistor 8 is thermally conductive with the main stationary contact 18 and is used to monitor the temperature of the main stationary contact 18. One end of the thermistor lead 81 is connected to the thermistor 8, and the other end is connected to the circuit board 2. The third terminal 82 is used to connect to the circuit board 2 to enable connection with multiple thermistors 8.

[0124] Thus, since the connection between multiple thermistor leads 81 and the third plug-in terminal 82 can be realized through the circuit board 2, the complexity and confusion of the wiring connection during the connection of multiple thermistor leads 81 and the third plug-in terminal 82 can be avoided, thereby further optimizing the wiring connection and layout of the relay 10, and at the same time facilitating the installation and maintenance by the installers.

[0125] In some embodiments, see Figure 13 As shown, the relay includes an insulating cover 19, two main stationary contacts 18, an active contact 17, a yoke plate 15, a moving iron core 13, a stationary iron core 9, and a push rod 14. The moving iron core 13 and the stationary iron core 9 are located on one side of the yoke plate 15, and the insulating cover 19 covers the other side of the yoke plate 15. The active contact 17 is located in the insulating cover 19, and the main stationary contacts 18 are located on the side of the active contact 17 away from the yoke plate 15 and pass through the insulating cover 19. The two ends of the push rod 14 are respectively connected to the moving iron core 13 and the active contact 17. The push rod 14 is movably passed through the yoke plate 15. The moving iron core 13 is movably arranged relative to the stationary iron core 9 and is used to drive the active contact 17 so that the two ends of the active contact 17 contact or separate from the two main stationary contacts 18.

[0126] Thus, the insulating cover 19 encloses the active contact 17, preventing operators from accidentally touching the energized active contact 17 and reducing the risk of electric shock. Simultaneously, it prevents external dust, moisture, and other impurities from entering the relay 10, affecting the performance of the active contact 17 and other electrical components, ensuring the stable operation of the relay 10 in complex environments. When the coil 7 of the relay 10 is energized, a magnetic field is generated, magnetizing the stationary iron core 9 and attracting the moving iron core 13. Under this attraction, the moving iron core 13 moves closer to the stationary iron core 9, causing the connected contacts to actuate, closing the previously open contacts and connecting the circuit. When the coil 7 is de-energized, the magnetic field disappears, and the moving iron core 13 moves away from the stationary iron core 9 under the action of the return spring, restoring the contacts to their initial state and disconnecting the circuit, thereby achieving on / off control of the circuit.

[0127] Furthermore, when coil 7 is energized, the moving iron core 13 moves relative to the stationary iron core 9, driving the push rod 14 to move. The movement of the push rod 14 causes the auxiliary contact group 11 to connect or disconnect. Since the auxiliary contact group 11 is connected to the electronic components' circuit, and the current connected to the electronic components in the auxiliary contact group 11 is a different low-voltage current from that in coil 7, the on / off state of the other low-voltage current can be controlled by the low-voltage current in coil 7. Simultaneously, relay 10 also includes a main contact group 16. When the main contact group 16 is closed, the auxiliary contact group 11 closes or opens; conversely, when the main contact group 16 is open, the auxiliary contact group 11 opens or closes accordingly. Thus, the on / off state of the main contact group can be monitored through the auxiliary contact group.

[0128] Meanwhile, the yoke plate 15 provides a low-resistivity circuit for the magnetic field generated by the coil 7 of the relay 10. This makes the magnetic field more concentrated and stronger, improves the electromagnetic conversion efficiency of the relay 10, and enables the moving iron core 13 to respond more sensitively to changes in the magnetic field of the coil 7, achieving fast and accurate operation.

[0129] For example, the active contact 17 and the main stationary contact 18 together form the main contact group 16. Thus, when the push rod 14 moves, it causes the active contact 17 to contact the main stationary contact 18. At this time, the active contact 17 and the main stationary contact 18 are connected to the circuit of the high-voltage electrical equipment. Since the current in the coil 7 is a low-voltage current, the on and off of the high-voltage current can be controlled by the low-voltage current.

[0130] In some embodiments, the conversion module 21 is located on the side of the yoke plate 15 away from the insulating cover 19.

[0131] Thus, the conversion module 21 and the main stationary contact 18, which passes through the insulating cover 19, are located on both sides of the relay body 4 along the first direction, thereby achieving spatial isolation between high voltage and low voltage and improving the safety of the relay body 4 in use.

[0132] In some embodiments, at least a portion of the auxiliary contact group 11 is located in the insulating cover 19 and between the yoke plate 15 and the active contact 17.

[0133] Thus, the insulating cover 19 provides electrical isolation, preventing short circuits or leakage between the auxiliary contact group 11 and other components, ensuring the safety and stability of the relay 10. At the same time, placing at least a portion of the auxiliary contact group 11 within the insulating cover 19 protects it from external environmental factors such as dust and moisture, thereby extending its service life.

[0134] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0135] 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
