Description

Technical Field

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

[0002] A relay is an electronically controlled component that uses a magnetic field generated by energizing a loop coil to drive internal moving components, which in turn cause the moving and stationary contacts to close or open, thereby controlling external loads (such as circuits).

[0003] In traditional technology, some relays have leads, typically using lead-out tabs located inside the relay housing, connecting the leads to relevant internal electrical components. However, these lead-out tabs take up internal space, hindering miniaturization and impacting the relay's performance and reliability. Utility Model Content

[0004] Therefore, it is necessary to provide a relay to address the problems of traditional technologies occupying installation space, hindering miniaturization design, and affecting performance and reliability.

[0005] This application discloses a relay comprising:

[0006] A shell having a shell wall that encloses a cavity, and a receiving portion is formed inside the shell wall;

[0007] Lead-out end, at least a portion of which is exposed on the surface of the housing; and

[0008] A lead-out member electrically connected to the lead-out end, and at least a portion of the lead-out member being installed in the receiving portion.

[0009] In this relay design, the lead-out terminal is mounted to the housing, with at least a portion of the lead-out terminal exposed on the housing surface. Then, at least a portion of the lead-out member is installed into a receiving portion formed within the housing wall, and the lead-out member is electrically connected to the lead-out terminal. This allows the lead-out terminal to be electrically connected to a corresponding electrical component within the housing, or to be led out to other surfaces of the housing, adaptable to different installation and usage scenarios. Compared to conventional technologies where the lead-out member is directly mounted inside the housing cavity, this design, by embedding at least a portion of the lead-out member within the receiving portion, avoids the lead-out member obstructing the housing cavity space. The enclosure reduces the difficulty of internal relay layout and facilitates miniaturization. Furthermore, the enclosure provides insulation and protection for the leads, minimizing the introduction of electrical clearances or creepage distances. Additionally, the enclosure serves to fix and limit the leads, preventing vibrations and displacement during transport or use that could affect the reliability of the connection between the leads and the external load. Finally, the leads, placed inside the enclosure, act as a framework, strengthening the housing and improving the relay's durability.

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.

[0038] 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.

[0039] 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.

[0040] 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.

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.

[0042] 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.

[0043] See Figure 1 The example shown is a relay 100, which is a high-voltage DC relay. In other alternative embodiments, the relay 100 may also be a high-voltage AC relay or the like, and can be flexibly selected according to actual needs.

[0044] For example, the relay 100 includes a housing 10, leads (not shown in the figure), and leads 20. The housing 10 is the main structural component of the relay 100, used to mount and fix the leads, leads 20, and other electrical components.

[0045] The shape of the shell 10 can be any one of cylinder, cuboid, etc., and the material of the shell 10 can be any one of metal, plastic, etc. These can be flexibly selected according to actual needs.

[0046] Please continue reading. Figure 2 and Figure 4 The shell 10 has a shell wall 11, which surrounds a shell cavity 12, and a receiving portion 111 is formed inside the shell wall 11.

[0047] For example, in this application, the shell 10 is in the shape of a cuboid, and therefore the shell 10 has six shell walls 11. At this time, the shell cavity 12 enclosed by the shell walls 11 is also in the shape of a cuboid.

[0048] Furthermore, at least a portion of the lead-out end is exposed on the surface of the housing 10; the lead-out member 20 is electrically connected to the lead-out end, and at least a portion of the lead-out member 20 is installed in the receiving portion 111.

[0049] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the relay 100 of this solution, the lead-out terminal is installed to the housing 10 and at least a portion of the lead-out terminal is exposed on the surface of the housing 10. Then, at least a portion of the lead-out member 20 is installed in the receiving portion 111 formed in the shell wall 11 of the housing 10, and the lead-out member 20 is electrically connected to the lead-out terminal. Thus, the lead-out terminal can be electrically connected to the corresponding electrical component in the housing 10 through the lead-out member 20, or the lead-out terminal can be led out to other surfaces of the housing 10 through the lead-out member 20, so as to be suitable for different installation and use scenarios.

[0050] Compared to the traditional method where the lead-out component 20 is directly installed inside the housing cavity 12, this solution incorporates at least a portion of the lead-out component 20 within the receiving portion 111. This avoids the lead-out component 20 occupying space in the housing cavity 12, reducing the difficulty of internal arrangement of the relay 100 and facilitating miniaturization of the relay 100. Furthermore, the housing wall 11 encloses the lead-out component 20, providing isolation and protection and minimizing the introduction of electrical clearances or creepage distances. Moreover, the housing wall 11 also serves to fix and limit the lead-out component 20, preventing it from vibrating or shifting due to external environmental vibrations during transport or use, thus ensuring reliable connection between the lead-out component 20 and the external load. Finally, with the lead-out component 20 positioned inside the housing wall 11, it acts as a framework, reinforcing the strength of the housing 10 and improving the durability of the relay 100.

[0051] Optionally, in one embodiment, the lead-out member 20 and the housing 10 are integrally formed. The integral forming process is simple, which helps to reduce the manufacturing difficulty of the lead-out member 20 and the housing 10. At the same time, the overall structural performance of the lead-out member 20 and the housing 10 is excellent, with high connection strength and good reliability.

[0052] For example, the shell 10 is made of plastic. During processing, the metal lead-out part 20 (such as copper) is placed in the mold cavity, and then injection molding material is injected into the mold cavity. The injection molding material wraps the lead-out part 20 inside. When the injection molding material cools and solidifies, it forms the shell 10, thereby realizing the integral molding and connection of the shell 10 and the lead-out part 20.

[0053] In actual processing, the receiving portion 111 formed in the shell wall 11 of the shell 10 can have a variety of specific implementation schemes.

[0054] For example, in an optional embodiment, the receiving portion 111 is a receiving channel formed within the shell wall 11, and at least a portion of the lead-out member 20 passes through the receiving channel. The receiving channel can be formed by machining (such as drilling, punching, boring, etc.), chemical etching, etc. The method of forming the receiving channel inside the shell wall 11 is simple, and then the lead-out member 20 can be directly inserted into the receiving channel, making the installation method simple.

[0055] It should be noted that the lead-out component 20 and the side wall of the receiving channel can be either a clearance fit or a tight fit. Preferably, the lead-out component 20 is installed tightly against the side wall of the receiving channel, and the side wall provides a positioning effect for the lead-out component 20, ensuring that the lead-out component 20 is installed firmly and reliably.

[0056] As an alternative to the above embodiment, in another optional embodiment, the housing 10 further includes a cover plate, and the receiving portion 111 is a receiving groove formed on the housing wall 11. The opening of the receiving groove communicates with the housing cavity 12, and at least a portion of the lead-out member 20 is embedded in the receiving groove. The cover plate is connected to the housing wall 11 and seals the opening of the receiving groove. When installing the lead-out member 20, it can be directly pressed into the cavity of the receiving groove through the opening of the receiving groove. The installation is simple, convenient, and efficient. Then, the cover plate is fixed to the housing wall 11, and the opening of the receiving groove is sealed by the cover plate to achieve encapsulation and isolation of the lead-out member 20, so as to avoid interference between the lead-out member 20 and other electrical components in the housing cavity 12.

[0057] Alternatively, as an alternative to the above embodiments, the housing 10 further includes a cover plate, and the receiving portion 111 is a receiving groove formed on the housing wall 11. The opening of the receiving groove is positioned away from the housing cavity 12 and communicates with the external environment of the housing 10. At least a portion of the lead-out member 20 is embedded in the receiving groove. The cover plate is connected to the housing wall 11 and seals the opening of the receiving groove. The difference from the above embodiments is that in this embodiment, the opening of the receiving groove is formed on the outer wall surface of the housing wall 11 of the housing 10, so that the lead-out member 20 is not affected by other electrical components that need to be installed in the housing cavity 12 when it is installed (in the above embodiments, it may be necessary to install the lead-out member 20 first and then install other electrical components to avoid the housing cavity 12 being occupied by electrical components after other electrical components are installed first, leaving insufficient operating space for installing the lead-out member 20). It can be conveniently and quickly installed into the receiving groove, and then sealed and protected by the cover plate. On the one hand, this ensures that the relay 100 has a simple and beautiful appearance, and on the other hand, it can prevent the live lead-out member 20 from causing damage to equipment or personnel outside the relay 100.

[0058] Based on the above embodiment, the shell wall 11 is provided with a first connecting part, and the cover plate is provided with a second connecting part, and the first connecting part and the second connecting part are detachably connected. Therefore, by detachably connecting the first connecting part and the second connecting part, the cover plate and the shell 10 can be detachably assembled, which facilitates the installation or removal of the lead-out part 20.

[0059] For example, the first connecting part and the second connecting part can be any of the following connection structures, including but not limited to snap-fit ​​connection, magnetic connection, adhesive connection, etc., and can be flexibly selected according to actual needs.

[0060] Please continue reading. Figures 1 to 3 Furthermore, in one embodiment, the lead-out terminal includes a load lead-out terminal 30, at least a portion of which is disposed within the housing cavity 12. It is understood that the load lead-out terminal 30 is specifically a stationary contact, which may be entirely installed inside the housing cavity 12, or partially installed inside the housing cavity 12 with the remainder extending outside the housing 10.

[0061] Please continue reading. Figure 2 , Figure 4 and Figure 5 The receiving part 111 is configured as a receiving channel, and the shell wall 11 is also provided with a first connecting hole 112. The receiving channel is connected to the shell cavity 12 through the first connecting hole 112. The lead-out part 20 includes a main body part 21 and a first mounting part 22 connected to each other. The main body part 21 passes through the receiving channel, and the first mounting part 22 passes through the first connecting hole 112 and partially extends into the shell cavity 12. The part of the first mounting part 22 extending into the shell cavity 12 is electrically connected to the load lead-out end 30.

[0062] The main body 21 passes through the receiving channel to realize the assembly and fixation of the lead-out member 20 and the housing wall 11; the first mounting part 22 extends into the housing cavity 12 through the first connecting hole 112 and can be electrically connected to the load lead-out terminal 30, so that the load lead-out terminal 30 can be led out to other surfaces of the housing 10 through the lead-out member 20, so that the relay 100 can meet different installation needs and improve installation flexibility.

[0063] For example, the first mounting part 22 has a mounting through hole, through which a portion of the stationary contact passes to achieve assembly and fixation. Furthermore, the end face of the portion of the stationary contact passing through the mounting through hole has a threaded hole, into which a screw is screwed. The threaded head of the screw can press the first mounting part 22 tightly against the stationary contact, thereby improving the connection strength and reliability between the first mounting part 22 and the stationary contact.

[0064] For example, one of the first mounting part 22 and the stationary contact is provided with a locking body, and the other of the first mounting part 22 and the stationary contact is provided with a fastening position. The locking body and the fastening position are engaged to fix the first mounting part 22 and the stationary contact, thereby improving the stability of their installation.

[0065] Please continue reading. Figure 2Furthermore, in one embodiment, the relay 100 further includes an insulating cover 40, which is disposed in the housing cavity 12. The load lead-out terminal 30 is a stationary contact, which is mounted on the insulating cover 40. Optionally, the insulating cover 40 is a square box structure made of ceramic material, which has good insulation protection performance and high durability.

[0066] For example, in actual production, the stationary contact is sealed and fixed to the insulating cover 40 by brazing.

[0067] Please continue reading. Figure 2 and Figure 3 Furthermore, based on the above embodiments, the relay 100 also includes a drive assembly 50 and a moving contact. The drive assembly 50 is disposed within the housing 12, and the load lead-out end 30 is a stationary contact. At least a portion of the stationary contact is disposed within an insulating cover 40. The moving contact is disposed within the insulating cover 40 and spaced apart from the stationary contact. The drive assembly 50 is driveably connected to the moving contact and can drive the moving contact to contact or separate from the stationary contact. The drive assembly 50 drives the moving contact to contact or separate from the stationary contact, thereby controlling the relay 100 to turn on or off, realizing the function and role of a control switch, and achieving on / off control of external loads.

[0068] For example, the drive component 50 uses an electromagnetic component, which is electrically connected to the external power supply that is matched with the relay 100. When the external power supply powers the electromagnetic component, the electromagnetic component generates a magnetic field and forms a reciprocating driving force to drive the moving contact to approach or move away from the stationary contact, thereby achieving the purpose of controlling the on / off state of the relay 100.

[0069] Please continue reading. Figure 2 In addition, based on any of the above embodiments, the relay 100 also includes a load connection terminal 60, the lead-out member 20 also includes a second mounting part 23, the second mounting part 23 is connected to the end of the main body 21 away from the first mounting part 22, and the shell wall 11 also has a second connecting hole 113, the receiving channel is connected to the external environment of the shell 10 through the second connecting hole 113.

[0070] The second mounting portion 23 extends into the second connecting hole 113, and the load connection end 60 is installed at the second connecting hole 113 and electrically connected to the second mounting portion 23. The load connection end 60 is exposed on the outer surface of the housing 10.

[0071] With this configuration, the load connection terminal 60 can be electrically connected to the lead-out member 20 by connecting to the second mounting part 23, and ultimately electrically connected to the stationary contact through the lead-out member 20, so that the stationary contact is led out through the lead-out member 20 to the mounting surface of the housing 10 where the load connection terminal 60 is located. In use, the load connection terminal 60 is used to electrically connect to an external load (such as a circuit) to realize the on / off control of the relay 100 on the external load.

[0072] For example, in this application, the stationary contact is located in the upper half of the housing 10. Being located in the upper half of the housing 10 can be understood as the stationary contact being inside the housing cavity 12, but arranged near the top of the housing 10; or the stationary contact being mounted on the top surface 114 of the housing 10.

[0073] The load connection terminal 60 is located at the bottom of the housing 10, thus enabling the stationary contact to be led out to the bottom of the housing 10 via the lead-out member 20 and the load connection terminal 60. Of course, depending on actual needs, the load connection terminal 60 can also be installed at other locations such as the side 115 or the top 114 of the housing 10, so as to lead the stationary contact out to the surface of the housing 10 facing any spatial orientation.

[0074] Furthermore, at least a portion of the load connection terminal 60 extends to the outside of the housing 10 through the second connecting hole 113. This exposes at least a portion of the load connection terminal 60 to the housing 10, ensuring that the exposed portion is not obstructed, thereby facilitating electrical connection to an external load and improving the ease of use of the relay 100.

[0075] Furthermore, when a portion of the load connection end 60 is exposed outside the housing 10, the remaining portion of the load connection end 60 is engaged within the second connecting hole 113, thereby improving the stability of the load connection end 60 installation.

[0076] Please continue reading. Figure 1 and Figure 2 Furthermore, in another embodiment of this application, the housing 10 includes a top surface 114, a side surface 115, and a bottom surface 116. The top surface 114 is connected to the bottom surface 116 via the side surface 115. A load connection terminal 60 is disposed on at least one of the top surface 114, the side surface 115, and the bottom surface 116. It is readily understood that the top surface 114, the side surface 115, and the bottom surface 116 of the housing 10 are configured to face different spatial orientations. When at least three load connection terminals 60 are installed on at least one of the top surface 114, the side surface 115, and the bottom surface 116, the relay 100 can flexibly adjust its spatial orientation according to different spatial environmental conditions or different external load installation requirements. This ensures that at least one load connection terminal 60 installed on the top surface 114, the side surface 115, and the bottom surface 116 is suitable for connecting to external loads, thereby improving the applicability and flexibility of the relay 100.

[0077] It is easy to understand that when the shell 10 is cuboid in shape, the top surface 114 and the side surface 115 are connected at 90° to each other, as are the side surface 115 and the bottom surface 116. In this case, there are four side surfaces 115, which are connected end to end along the circumference, and adjacent side surfaces 115 are connected at 90° to each other.

[0078] Please continue reading. Figure 1Furthermore, in some other embodiments, the lead-out includes a coil lead-out 70, and the lead-out member 20 electrically connects the coil lead-out 70 and a coil located inside the housing 10. The coil lead-out 70 can supply power to the coil. For example, the coil lead-out 70 is mounted in the upper part of the housing 10, and a portion of the coil lead-out 70 is exposed on the top wall of the housing 10 to facilitate connection of the coil lead-out 70.

[0079] For example, the coil lead 70 can be made of copper sheet, but is not limited to copper sheet; the shape, structure, size, etc. of the copper sheet can be flexibly selected according to actual needs, and no specific limitation is made here.

[0080] Furthermore, the lead-out includes a detection lead-out 80, and the lead-out member 20 electrically connects the detection lead-out 80 and the load lead-out 30. The detection lead-out 80 is used to detect the closing status of the relay 100. For example, the detection lead-out 80 is installed in the upper part of the housing 10, and a portion of the detection lead-out 80 is exposed on the top wall of the housing 10 to facilitate connection of the detection lead-out 80.

[0081] For example, the detection lead 80 can be made of copper sheet, but is not limited to copper sheet; the shape, structure, size, etc. of the copper sheet can be flexibly selected according to actual needs, and no specific limitation is made here.

[0082] Furthermore, this application provides two coil leads 70 and two detection leads 80. The two coil leads 70 and the two detection leads 80 are respectively arranged at the four apex corners of the top surface 114 of the housing 10, and the two coil leads 70 and the two detection leads 80 can be electrically connected to external devices by surface-mount soldering. Increasing the number of coil leads 70 and detection leads 80 helps to improve the reliability of the connection with external devices.

[0083] It should be noted that the above-mentioned surface welding specifically refers to the ability of the coil lead-out end 70 and the detection lead-out end 80 to be welded together with the connection parts of the external equipment in a surface-to-surface manner to achieve electrical connection, and to increase the welding area to obtain higher connection strength and reliability.

[0084] The technical features of the above embodiments can be combined in any way.
