The mounting shell is connected to one end of the mounting cup and communicates with the mounting cup to form a mounting cavity. The supporting cover is arranged at the end of the mounting cup away from the mounting shell and seals the mounting cavity. The supporting cover has a first lead-through hole. The contact assembly is arranged in the mounting cup and comprises an auxiliary lead-through piece. The auxiliary lead-through piece is arranged through the first lead-through hole. The coil assembly is located outside the shell assembly and is sleeved on the mounting shell. The coil assembly comprises a coil lead-through piece. The coil lead-through piece is located outside the shell assembly. In this way, the auxiliary lead-through piece is led out through the supporting cover in the mounting cavity, and the coil lead-through piece is directly led out outside the shell assembly, so that the coil lead-through piece does not need to be led out through the supporting cover. Therefore, the number of holes in the supporting cover can be reduced, the risk of air leakage of the supporting cover is lowered, and the sealing performance of the relay is improved.

Description

Technical Field

[0001] This application relates to the field of power electrical appliances technology, and in particular to a relay. Background Technology

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

[0003] In current relays, the support cover needs to have openings to allow the stationary contact, auxiliary lead, and coil lead to pass through. However, the large number of openings on the support cover increases the risk of air leakage, affecting the relay's performance. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the large number of openings in the support cover of current relays easily leads to the risk of air leakage. A new type of relay should be provided that allows the coil leads to be led out without passing through the support cover, thereby reducing the number of openings on the support cover, lowering the risk of air leakage, and improving the relay's sealing performance.

The support body is disposed on the support base, the third adapter is disposed on the support base, the second adapter is integrated into the support body, and the fixing body is disposed on one end of the support body away from the support base and can be engaged with the edge of the mounting cup.

[0021] The support base, the support body, and the fixing body are integral structures, and / or the support base, the support body, and the fixing body are made of insulating material.

[0025] In one embodiment of this application, the connector includes a connecting body and a first output terminal and a second output terminal disposed on the connecting body. The connecting body is disposed on the support frame.

[0034] By adopting the above technical solution, this application has at least the following technical effects:

[0035] The relay of this application has mounting cups connected and communicating with each other to form a mounting cavity. A support cover is disposed in the mounting cup and seals the mounting cavity. A contact assembly is disposed in the mounting cavity. An auxiliary lead of the contact assembly passes through the first lead hole of the support cover to extend out of the housing assembly. A coil assembly is located outside the housing assembly and is sleeved on the mounting shell so that the coil lead of the coil assembly is directly led out from the outside of the housing assembly.

[0036] In this way, the relay uses a mounting cup connected to the mounting housing to form an independent mounting cavity, which is sealed by a support cover. The auxiliary lead extends through the support cover within the mounting cavity, while the coil lead extends directly from the outside of the housing assembly, eliminating the need for the coil lead to pass through the support cover.

Detailed Implementation

[0052] 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.

[0053] 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 element 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] Understandably, a relay is an electronic control device that plays a role in circuits, including automatic adjustment, safety protection, and circuit switching. In current relays, the support cover needs openings to allow the stationary contact, auxiliary leads, and coil leads to pass through. However, a large number of openings in the support cover increases the risk of air leakage, affecting the relay's performance.

[0059] For this purpose, please refer to Figures 1 to 5 This application provides a relay 100. Figure 1 This is a schematic diagram of a relay 100 according to an embodiment of this application. Figure 2 for Figure 1 The diagram shown is a schematic representation of the relay 100 with its housing 160 and coil assembly 130 removed from one viewpoint. Figure 3 for Figure 2 The diagram shown is a schematic representation of the relay 100 from another perspective. Figure 4 for Figure 2 The top view of relay 100 shown. Figure 5 for Figure 4 The relay 100 shown is a cross-sectional view along AA.

[0060] Optionally, relay 100 is a high-voltage DC relay, and optionally, relay 100 is an epoxy-sealed relay. For high-voltage DC relays, the housing assembly 110 is filled with nitrogen or other inert gases for arc extinguishing. To prevent leakage of nitrogen or other inert gases, epoxy adhesive or ceramic welding is typically used to seal the housing assembly 110. This differs from the sealing requirements and measures of relay 100 in this application, where the adhesive is used for dust prevention.

[0061] The relay 100 of this application has its auxiliary lead-out member 121 led out through the support cover 113 in the mounting cavity, while the coil lead-out member 131 is led out directly on the outside of the housing assembly 110, so that the coil lead-out member 131 does not need to pass through the support cover 113. This reduces the number of openings on the support cover 113, lowers the risk of air leakage from the support cover 113, and improves the sealing performance of the relay 100. The specific structures of the relay 100 in some embodiments are described below.

[0062] See Figures 1 to 9 In one embodiment, the relay 100 includes a housing assembly 110, a contact assembly 120, and a coil assembly 130. The housing assembly 110 includes a mounting cup 111, a mounting shell 112, and a support cover 113. The mounting shell 112 is connected to one end of the mounting cup 111 and communicates with the mounting cup 111 to form a mounting cavity (not shown). The support cover 113 is disposed at the end of the mounting cup 111 opposite to the mounting shell 112 and seals the mounting cavity. The support cover 113 has a through first lead-out hole. The contact assembly 120 is disposed in the mounting cup 111 and includes an auxiliary lead-out member 121 that passes through the first lead-out hole (not shown). The coil assembly 130 (not shown) is located outside the housing assembly 110 and is fitted onto the mounting shell 112. The coil assembly 130 includes a coil lead-out member 131 located outside the housing assembly 110. Figure 6 for Figure 2 The diagram shown is a schematic of the relay 100 with part of the mounting cup 111 and support cover 113 removed. Figure 7 for Figure 1 The cross-sectional view of relay 100 shown is shown. Figure 8 for Figure 1 The diagram shown is a schematic representation of the relay 100 with its housing 160 removed from one viewpoint. Figure 9 for Figure 8 A schematic diagram of the relay 100 shown from another perspective.

[0063] The housing assembly 110 is a sealed structure within the relay 100. The contact assembly 120 is disposed within the housing assembly 110 and can contact or separate within the housing assembly 110 to control the on or off state of the relay 100. The coil assembly 130 is located outside the housing assembly 110. This application uses... Figure 2 and Figure 5 The vertical direction (top-bottom direction, height direction) shown is used as a reference to describe the structure of relay 100, which will not be repeated later.

[0064] Specifically, in the housing assembly 110, the mounting cup 111 is hollow, with an open top and a connecting hole in the central region of its bottom. The mounting shell 112 has an open top and a closed bottom. The mounting shell 112 is located below the mounting cup 111 and connected to its lower surface. The mounting shell 112 covers the connecting hole, and the mounting shell 112 communicates with the mounting cup 111 through the connecting hole.

[0065] Thus, the mounting cup 111 and the mounting shell 112 can form an independent mounting cavity after they are connected. The support cover 113 is disposed in the mounting cup 111 and can seal the mounting cup 111 at the opening at the top of the mounting cup 111. At this time, the support cover 113, the mounting cup 111, and the mounting shell 112 can form a sealed mounting cavity. The support cover 113 has a through first outlet hole, which connects the outside of the housing assembly 110 and the mounting cavity.

[0066] The contact assembly 120 is capable of contacting or separating within a sealed mounting cavity. The contact assembly 120 includes an auxiliary lead-out 121 that passes through a first lead-out hole. Thus, the auxiliary lead-out 121 is partially located within the mounting cavity and partially located outside the housing assembly 110. The portion of the auxiliary lead-out 121 outside the housing assembly 110 can be electrically connected to an external control circuit, allowing feedback on the contact assembly 120's contact or separation status within the mounting cavity. It should be noted that, in addition to providing feedback on the contact assembly 120's contact or separation status, the auxiliary lead-out 121 may also have other functions within the relay 100, which will not be elaborated here.

[0067] The coil assembly 130 is located outside the housing assembly 110, and can be fitted onto the outside of the mounting shell 112. The coil assembly 130 has a coil lead-out member 131, which can be directly led out from the outside of the housing assembly 110. Because the mounting cup 111 and the mounting shell 112 form an independent mounting cavity, the coil lead-out member 131 will not pass through the mounting shell 112, the mounting cup 111, and the support cover 113 for wiring; the coil lead-out member 131 can be directly led out to the outside of the housing assembly 110.

[0068] In this way, only the first lead-out hole needs to be opened on the support cover 113 for the auxiliary lead-out component 121 to run, and there is no need to open holes on the support cover 113 for the coil lead-out component 131 to run, thus reducing the number of openings on the support cover 113. It is understandable that if there are many openings on the support cover 113, even if sealing treatment is performed, there is still a risk of air leakage at each opening. In order to reduce the risk of air leakage, this application leads the coil lead-out component 131 out from the outside of the housing assembly 110, thereby reducing the number of openings on the support cover 113.

[0069] In the relay 100 of the above embodiment, a mounting cup 111 is connected to a mounting housing 112 to form an independent mounting cavity, which is sealed by a support cover 113. An auxiliary lead 121 extends through the support cover 113 within the mounting cavity, while a coil lead 131 extends directly from the outside of the housing assembly 110, eliminating the need for the coil lead 131 to pass through the support cover 113. This reduces the number of openings in the support cover 113, lowers the risk of leakage, and improves the sealing performance of the relay 100.

[0070] The relay 100 of this application is a sealed relay. Compared with other common types of relays, the relay 100 has higher requirements for sealing performance, especially the sealing of the support cover 113 to the mounting housing 112, so as to seal the space where the contact assembly 120 is located. By reducing the number of openings in the support cover 113, the relay of this application can reduce the risk of air leakage in the support cover 113 and further improve the sealing performance of the relay 100.

[0071] In this embodiment, there are two auxiliary leads 121 and two coil leads 131. Correspondingly, there are also two components electrically connected to the auxiliary leads 121 and two components electrically connected to the coil leads 131, which will not be described further below. Of course, in other embodiments of this application, the number of auxiliary leads 121 and coil leads 131 may be different.

[0072] See Figures 1 to 6In one embodiment, at least one of the mounting cup 111 and the mounting shell 112 is made of a metal material. This ensures that the mounting cup 111 and the mounting shell 112 have a certain structural strength to provide a certain supporting force and protect the internal components of the mounting cup 111 and the mounting shell 112. Simultaneously, it also enables the mounting cup 111 and the mounting shell 112 to have magnetic conductivity. In another embodiment, the mounting cup 111 and the mounting shell 112 are made of iron. That is, the mounting cup 111 and the mounting shell 112 are iron cups. This ensures that the mounting cup 111 and the mounting shell 112 have a certain structural strength to provide a certain supporting force and protect the internal components of the mounting cup 111 and the mounting shell 112. Simultaneously, it also enables the mounting cup 111 and the mounting shell 112 to have magnetic conductivity. Of course, in other embodiments of this application, the mounting cup 111 and the mounting shell 112 may also be made of other magnetically conductive metal materials.

[0073] See Figures 2 to 6 In one embodiment, the mounting cup 111 and the mounting shell 112 are welded together. That is, the mounting cup 111 and the mounting shell 112 are connected by welding. This ensures the reliability of the connection between the mounting cup 111 and the mounting shell 112, guarantees the sealing of the connection point, avoids the risk of air leakage, and also facilitates the connection between the mounting cup 111 and the mounting shell 112, reducing the difficulty of connection. Of course, in other embodiments of this application, the mounting cup 111 and the mounting shell 112 may also be an integral structure.

[0074] See Figures 2 to 6 In one embodiment, sealant is filled between the auxiliary lead-out member 121 and the first lead-out hole. That is, after the auxiliary lead-out member 121 passes through the first lead-out hole, sealant is injected between the auxiliary lead-out member 121 and the first lead-out hole. The sealant ensures the sealing of the connection between the auxiliary lead-out member 121 and the support cover 113, reducing the risk of air leakage.

[0075] Optionally, the sealant is epoxy adhesive. Epoxy adhesive is a high-performance adhesive that ensures a reliable connection between the auxiliary lead-out component 121 and the support cover 113 while also guaranteeing a tight seal between them. It is worth noting that all sealants mentioned below are epoxy adhesives, and will not be described further.

[0076] See Figures 2 to 6In one embodiment, sealant is filled between the support cover 113 and the mounting housing 112. After the components of the relay 100 are installed onto the mounting cup 111 and the mounting housing 112, the support cover 113 is installed onto the mounting cup 111. Sealant is injected at the connection between the support cover 113 and the mounting cup 111 to ensure the sealing of the connection and reduce the risk of leakage.

[0077] See Figures 1 to 5 In one embodiment, the relay 100 further includes an air tube (not shown), and the support cover 113 also has a mounting hole that extends through the support cover 113. The air tube passes through the mounting hole, and sealant is filled between the air tube and the mounting hole. The mounting hole extends through the support cover 113 to connect the outer side of the housing assembly 110 with the mounting cavity. The air tube can pass through the mounting hole, partially located inside and partially located outside the housing assembly 110, and inert gas can be injected into the mounting cavity through the air tube.

[0078] Furthermore, after the trachet is installed in the support cover 113, sealant is injected at the connection between the trachet and the support cover 113 to ensure the airtightness of the connection and reduce the risk of leakage. Additionally, a sealing element (not shown) is provided at the end of the trachet on the outside of the housing assembly 110 to seal the trachet and prevent inert gas from escaping through the trachet after injection.

[0079] See Figures 2 to 6 In one embodiment, the contact assembly 120 further includes a movable contact 122, an auxiliary movable spring 123, and a stationary contact 124. The support cover 113 has a through-hole (not shown), through which the stationary contact 124 passes. The movable contact 122 is movably disposed on the mounting cup 111 and is disposed opposite to the stationary contact 124. The auxiliary movable spring 123 is disposed on the movable contact 122 and is disposed opposite to the auxiliary lead-out member 121. When the movable contact 122 moves, it can abut against or disengage from the stationary contact 124, so that the movable contact 122 drives the auxiliary movable spring 123 to abut against or disengage from the auxiliary lead-out member 121.

[0080] The stationary contact 124 and the moving contact 122 are arranged opposite each other along the height direction. After the stationary contact 124 passes through the second lead hole, part of the stationary contact 124 is located in the mounting cavity, and part is located outside the housing assembly 110. The part of the stationary contact 124 outside the housing assembly 110 can be connected to the circuit through a conductive component, and the part of the stationary contact 124 in the mounting cavity can be arranged opposite to the moving contact 122. When the moving contact 122 moves along the height direction, the moving contact 122 can contact or separate from the stationary contact 124 to turn the relay 100 on or off, thereby enabling the relay 100 to connect the circuit or disconnect the circuit.

[0081] Furthermore, an auxiliary moving spring 123 is provided on the side of the moving contact 122, and the auxiliary moving spring 123 is arranged opposite to the auxiliary lead-out member 121 along the height direction. When the moving contact 122 contacts or separates from the stationary contact 124 along the height direction, the moving contact 122 can synchronously drive the auxiliary moving spring 123 to move along the height direction, so that the auxiliary moving spring 123 contacts or separates from the auxiliary lead-out member 121.

[0082] In this way, the contact or separation between the auxiliary lead-out 121 and the auxiliary moving spring 123 can reflect the contact and separation relationship between the moving contact 122 and the stationary contact 124, facilitating the monitoring of the contact or separation between the moving contact 122 and the stationary contact 124 and improving the safety of the relay 100. Moreover, after the auxiliary lead-out 121 extends through the support cover 113, it can be connected to an external control circuit on the outside of the housing assembly 110 to realize the monitoring and feedback of the contact and separation between the moving contact 122 and the stationary contact 124.

[0083] See Figures 2 to 5 In one embodiment, sealant is filled between the stationary contact 124 and the second lead-out hole. That is, after the stationary contact 124 passes through the second lead-out hole, sealant is injected between the stationary contact 124 and the second lead-out hole. The sealant ensures the sealing of the connection between the stationary contact 124 and the support cover 113, reducing the risk of air leakage.

[0084] See Figure 5 In one embodiment, the relay 100 further includes a push assembly 140, the top of which is located in the mounting cup 111 and connected to the moving contact 122. The remaining portion of the push assembly 140 is located in the mounting housing 112. The push assembly 140 is movable in the height direction within the mounting housing 112 to push the moving contact 122 to move in the height direction. Furthermore, after the coil assembly 130 is fitted onto the outside of the mounting housing 112, the coil assembly 130 is also fitted onto the outside of the push assembly 140.

[0085] Understandably, the actuating assembly 140 has a moving iron core (not shown) and a stationary iron core (not shown). The moving iron core can be attracted to the stationary iron core under the magnetic field of the coil assembly 130, thereby driving the actuating assembly 140 to push the moving contact 122 into contact with the stationary contact 124 to turn on the relay 100. After the magnetic field disappears, the moving iron core can return to its initial position to separate from the stationary iron core, thereby driving the actuating assembly 140 to separate the moving contact 122 from the stationary contact 124 to turn off the relay 100. It is worth noting that the specific structure of the actuating assembly 140 is not the focus of this application and will not be described in detail below.

[0086] In one embodiment, the coil assembly 130 further includes a coil frame 132 and a coil body 133. The coil frame 132 is fitted onto the mounting shell 112, and the coil body 133 is mounted on the coil frame 132 and electrically connected to the coil lead-out member 131. The coil frame 132 is the main frame of the coil assembly 130, fitted onto the outside of the mounting shell 112. The coil body 133 is the main component of the coil assembly 130 that generates the magnetic field, and is fitted onto the coil frame 132.

[0087] One end of the coil body 133 is electrically connected to the coil lead 131, which can be electrically connected to an external control circuit, thereby connecting the coil body 133 to the external control circuit. In this way, the external control circuit can supply or de-energize the coil body 133 through the coil lead 131 to realize the on / off control of the coil body 133, and then control the push assembly 140 to push the moving contact 122 to abut or disengage from the stationary contact 124.

[0088] See Figures 1 to 12 In one embodiment, the relay 100 further includes a connection assembly 150 located outside the housing assembly 110 and electrically connected to the auxiliary lead-out member 121 and the coil lead-out member 131. Figure 10 for Figure 2 The diagram shown is a schematic representation of the connection component 150 in the relay 100 from one perspective. Figure 11 for Figure 10 A schematic diagram of the connecting component 150 shown from another perspective. Figure 12 for Figure 10 An exploded view of the connecting component 150 shown.

[0089] The connection component 150 is a transition component that enables the relay 100 to be electrically connected to an external control circuit. The connection component 150 can be electrically connected to the auxiliary lead-out member 121 and the coil lead-out member 131. At the same time, the connection component 150 can also be electrically connected to an external control circuit to connect the auxiliary lead-out member 121 and the coil lead-out member 131 to the external control circuit.

[0090] The connecting component 150 is disposed on the outer shell 160 of the housing component 110. The auxiliary lead 121 passes through the support cover 113 and is electrically connected to the connecting component 150. The coil lead 131 is directly led out from the outside of the housing component 110 to the connecting component 150 and is electrically connected to the connecting component 150, thereby realizing the connection between the auxiliary lead 121, the coil lead 131, and the connecting component 150.

[0091] See Figures 1 to 12In one embodiment, the connecting assembly 150 includes a support frame 151 and a connector 152. The support frame 151 is located outside the mounting housing 112 and is disposed on the coil frame 132 of the coil assembly 130. The connector 152 is electrically connected to the auxiliary lead-out member 121 and the coil lead-out member 131, and is also electrically connected to an external control circuit. The support frame 151 is a bracket in the connecting assembly 150 that supports the installation. The support frame 151 is disposed on the coil frame 132 and located outside the mounting cup 111, and supports the auxiliary lead-out member 121 and the coil lead-out member 131.

[0092] Connector 152 is a component that is electrically connected to an external control circuit. Furthermore, the auxiliary connector 121 and coil lead 131 can also be electrically connected to connector 152, allowing the auxiliary connector 121 and coil lead 131 to access the external control circuit. Support bracket 151 supports connector 152, fixing it in place and preventing movement due to vibration or other factors, ensuring reliable connection between connector 152 and the external control circuit, auxiliary connector 121, and coil lead 131.

[0093] Meanwhile, the support frame 151 is disposed behind the coil frame 132, and the coil frame 132 can support the support frame 151, which is beneficial to the stability of the support frame 151, thereby improving the stability of the connector 152 and facilitating the connection between the relay 100 and the external control circuit. Of course, in other embodiments of this application, the relay 100 may also include other fixing components, and the support frame 151 is disposed on the fixing components, as long as it can stably support the support frame 151.

[0094] See Figures 1 to 12 In one embodiment, the connection assembly 150 further includes a conductive adapter 153, which includes a first adapter 1531, a second adapter (not shown), and a third adapter 1532. The first adapter 1531 is electrically connected to the auxiliary lead-out member 121 on the outside of the support cover 113. The second adapter is integrated into the support frame 151 and electrically connects the first adapter 1531 and the third adapter 1532. The third adapter 1532 is disposed on the support frame 151 and electrically connected to the connector 152.

[0095] The conductive adapter 153 is a component that electrically connects the auxiliary lead-out 121 to the connector 152. It is understood that after the auxiliary lead-out 121 extends through the support cover 113, a certain gap exists between the auxiliary lead-out 121 and the connector 152, affecting their connection. Therefore, this application uses the conductive adapter 153 to connect the auxiliary lead-out 121 and the connector 152, achieving electrical connection between them.

[0096] Specifically, the second adapter is integrated into the support frame 151. One end of the first adapter 1531 is electrically connected to the auxiliary lead-out member 121 on the outside of the support cover 113, and the other end of the first adapter 1531 is electrically connected to one end of the second adapter. The third adapter 1532 is disposed on the support frame 151. One end of the third adapter 1532 is electrically connected to the other end of the second adapter, and the other end of the third adapter 1532 is electrically connected to the connector 152, so as to realize the electrical connection between the auxiliary lead-out member 121 and the connector 152.

[0097] In one embodiment, the first adapter 1531, the second adapter, and the third adapter 1532 are connecting wires, conductive sheets, or other components capable of conducting electricity. In this embodiment, the first adapter 1531 is a conductive sheet, the second adapter is a connecting wire, and the third adapter 1532 is a conductive pin, which is inserted into the connector 152. Of course, in other embodiments of this application, the first adapter 1531, the second adapter, and the third adapter 1532 may have other structures.

[0098] See Figures 1 to 12 In one embodiment, the support frame 151 includes a support base 1511, a support body 1512, and a fixing body 1513. The support body 1512 is disposed on the support base 1511, a third adapter 1532 is disposed on the support base 1511, a second adapter is integrated into the support body 1512, and the fixing body 1513 is disposed on one end of the support body 1512 away from the support base 1511 and can be locked onto the edge of the mounting cup 111.

[0099] The support base 1511 serves as the mounting base for the support frame 151. The support base 1511 is mounted on the coil support. The support body 1512 extends along the height direction and is mounted on the support base 1511. The support base 1511 supports and mounts the third adapter 1532, the coil lead-out member 131, and the connector 152. Simultaneously, the support body 1512 integrates the second adapter, facilitating the electrical connection of the conductive adapter 153 to the auxiliary lead-out member 121 and the connector 152.

[0100] The fixing body 1513 is disposed on top of the supporting body 1512 and extends toward the auxiliary lead-out member 121. That is, the fixing body 1513, the supporting body 1512, and the supporting base 1511 are arranged in a roughly Z-shape. In this way, the fixing body 1513 can overlap the edge of the mounting cup 111 to lock onto the edge of the mounting cup 111, thereby fixing the supporting frame 151 to the mounting cup 111. At the same time, the coil frame 132 can also support the supporting frame 151, so that the supporting frame 151 is reliably fixed.

[0101] In one embodiment, the fixing body 1513, the supporting body 1512, and the supporting base 1511 are an integral structure. This ensures the structural strength of the fixing body 1513, the supporting body 1512, and the supporting base 1511, enabling the support frame 151 to perform its supporting function. It also reduces the number of parts and facilitates assembly. Of course, the fixing body 1513, the supporting body 1512, and the supporting base 1511 can also be provided separately. In one embodiment, the fixing body 1513, the supporting body 1512, and the supporting base 1511 are made of insulating material.

[0102] See Figures 1 to 12 In one embodiment, the coil holder 132 includes a main support 1321 and an extension support 1322. The coil body 133 of the coil assembly 130 is mounted on the main support 1321. The extension support 1322 is disposed on the main support 1321 and extends toward the side of the mounting cup 111. The support frame 151 is mounted on the extension support 1322. The coil lead-out member 131 is disposed on the extension support 1322 for connection with the connector 152.

[0103] The main support 1321 serves as the mounting bracket for the coil body 133. The main support 1321 can be fitted onto the mounting shell 112, and the coil body 133 is mounted on the main support 1321. The extension bracket 1322 serves as the mounting bracket for the coil lead 131. The extension bracket 1322 extends radially along the main support 1321 and is located below the support frame 151. The support frame 151 can be mounted on the extension bracket 1322, and the extension bracket 1322 supports and mounts the support frame 151.

[0104] In one embodiment, the main support 1321 and the extension support 1322 are an integral structure. This ensures the structural strength of the connection between the main support 1321 and the extension support 1322, thus providing support, while also reducing the number of parts and facilitating assembly. Of course, in other embodiments of this application, the main support 1321 and the extension support 1322 can also be provided separately.

[0105] See Figures 1 to 12 In one embodiment, the support base 1511 of the support frame 151 has a first mating portion 1514, and the extension bracket 1322 has a second mating portion (not shown). The first mating portion 1514 and the second mating portion are correspondingly arranged and cooperate to fix the support frame 151 to the coil frame 132. One of the first mating portion 1514 and the second mating portion is a mating protrusion, and the other is a mating groove.

[0106] The lower surface of the support base 1511 has a first mating portion 1514, and the upper surface of the extension bracket 1322 has a second mating portion. After the support frame 151 is installed onto the extension bracket 1322, the first mating portion 1514 and the second mating portion engage to fix the support frame 151 to the extension bracket 1322. In this embodiment, the first mating portion 1514 is a mating protrusion, and the second mating portion is a mating groove. Of course, in other embodiments of this application, the first mating portion 1514 may be a mating groove, and the second mating portion may be a mating protrusion.

[0107] See Figures 1 to 12 In one embodiment, the connector 152 includes a connecting body 1521 and a first output terminal 1522 and a second output terminal 1523 disposed on the connecting body 1521. The connecting body 1521 is disposed on the support frame 151. An auxiliary lead-out member 121 is electrically connected to the first output terminal 1522 through the connecting body 1521, and a coil lead-out member 131 is electrically connected to the second output terminal 1523 through the connecting body 1521.

[0108] The connecting body 1521 is the main structure of the connector 152. The connecting body 1521 can be plugged into and connected to the coil lead 131 and the third adapter 1532 so that the connecting body 1521 can be fixed to the support frame 151. At the same time, the connecting body 1521 is also provided with a first output terminal 1522 and a second output terminal 1523, which can be electrically connected to an external control circuit.

[0109] Thus, after the auxiliary lead-out 121 is plugged into the connecting body 1521 via the conductive adapter 153, it can be electrically connected to the first output terminal 1522, and then electrically connected to the external control circuit through the first output terminal 1522. After the coil lead-out 131 is plugged into the connecting body 1521, it can be electrically connected to the second output terminal 1523, and then electrically connected to the external control circuit through the second output terminal 1523. Optionally, the first output terminal 1522 and the second output terminal 1523 can be conductive pins or the like.

[0110] See Figures 1 to 12 In one embodiment, the relay 100 further includes a housing 160, a housing assembly 110 and a coil assembly 130 disposed within the housing 160. The housing 160 includes a base 161 and a top cover 162. The coil assembly 130 is disposed within the base 161, the housing assembly 110 is at least partially disposed within the base 161, and the top cover 162 covers the base 161. This application restructures the housing 160 after extending the coil lead 131 outside the housing assembly 110 to meet the lead-out requirements of the coil lead 131.

[0111] Specifically, the housing 160 includes a base 161 and a top cover 162. The coil assembly 130 and the mounting housing 112 are located within the base 161, and the mounting cup 111 is located outside the base 161. After the top cover 162 is placed over the base 161, the top cover 162 can cover the mounting cup 111. In this way, all the components of the relay 100 are located within the housing 160 to protect the various components of the relay 100. At the same time, the coil lead 131 can be led out between the base 161 and the top cover 162, facilitating the lead-out of the coil lead 131.

[0112] See Figures 1 to 12 In one embodiment, the base 161 has a first fastening portion 1611, and the upper cover 162 has a second fastening portion 1621 corresponding to the first fastening portion 1611. The first fastening portion 1611 and the second fastening portion 1621 are connected to fix the upper cover 162 to the base 161. One of the first fastening portion 1611 and the second fastening portion 1621 is a hook, and the other is a groove. After the upper cover 162 is placed on the base 161, the second fastening portion 1621 of the upper cover 162 can be fastened to the first fastening portion 1611 of the base 161, thus fixing the upper cover 162 to the base 161.

[0113] In this embodiment, the first fastening part 1611 is a hook, and the second fastening part 1621 is a slot, with the hook engaged in the slot. Of course, in other embodiments of this application, the first fastening part 1611 may be a slot, the second fastening part 1621 may be a hook, or both the first fastening part 1611 and the second fastening part 1621 may be hooks, etc.

[0114] See Figures 1 to 12 In one embodiment, the top cover 162 and / or the base 161 have a fixed shell 1612 protruding from the periphery, and the connecting assembly 150 is located in the fixed shell 1612, with the first output terminal 1522 and the second output terminal 1523 in the connecting assembly 150 exposed in the fixed shell 1612.

[0115] In this embodiment, a fixing shell 1612 is provided on one side of both the upper cover 162 and the base 161. The fixing shell 1612 protrudes from the periphery of the upper cover 162 and the base 161. The support base 1511 and the extension bracket 1322 are located in the fixing shell 1612, and the connector 152 is also located in the fixing shell 1612 and exposed through the fixing shell 1612. In this way, the first output terminal 1522 and the second output terminal 1523 can expose the relay 100, which is convenient for electrical connection with external control circuits. Of course, in other embodiments, the fixing shell 1612 may only be provided on the upper cover 162 or only on the base 161.

[0116] See Figures 1 to 12In one embodiment, the upper cover 162 has an opening (not shown) at the end opposite to the base 161, and the opening is filled with sealant to seal the upper cover 162 and the support cover 113. That is, after the upper cover 162 is placed on the base 161, the support cover 113, the mounting cup 111, the support frame 151, and the auxiliary lead-out member 121 can be exposed through the opening. To further improve the sealing performance of the relay 100, sealant is injected into the opening. In this way, the sealant can form a cover structure at the opening of the upper cover 162, further improving the sealing performance.

[0117] The relay 100 of this application uses a mounting cup 111 connected to a mounting housing 112 to form an independent mounting cavity, which is sealed by a support cover 113. An auxiliary lead 121 extends through the support cover 113 within the mounting cavity, while a coil lead 131 extends directly from the outside of the housing assembly 110, eliminating the need for the coil lead 131 to pass through the support cover 113. This reduces the number of openings in the support cover 113, lowers the risk of leakage, and improves the sealing performance of the relay 100.

[0118] Furthermore, the mounting cup 111 and the mounting shell 112 are connected by welding, improving the reliability of the connection between the mounting cup 111 and the mounting shell 112. Furthermore, sealant is filled between the auxiliary lead-out member 121 and the first lead-out hole to ensure the seal between the auxiliary lead-out member 121 and the support cover 113. Furthermore, sealant is filled between the support cover 113 and the mounting shell 112 to ensure the seal between the support cover 113 and the mounting shell 112.

[0119] Furthermore, the outer casing 160 adopts a structure in which the upper cover 162 and the base are separately set, so that the coil lead-out member 131 can be led out from the outside of the casing assembly 110. Furthermore, the upper cover 162 and the base 161 are connected by a first fastening part 1611 and a second fastening part 1621, which facilitates the fixing of the upper cover 162 and the base 161.

[0120] 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.

[0121] The embodiments described above are merely illustrative of 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.
