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] Currently, some relays are equipped with leads and stationary contacts, with the leads needing to be connected to the stationary contacts via connecting pieces. However, this traditional approach not only imposes certain limitations on the installation of the leads but also causes inconvenience in the installation of the stationary contacts. Furthermore, when a large number of leads are required, it significantly increases the difficulty of installing the leads and can also lead to problems such as excessively high installation heights. Utility Model Content

[0004] Therefore, it is necessary to provide a relay to address the problems of poor installation flexibility, inconvenient operation, and excessive installation height associated with traditional technologies.

[0005] This application discloses a relay comprising:

[0006] Static contact head;

[0007] A conductive base is disposed inside the housing of the relay and is electrically connected to the stationary contact;

[0008] Lead-out terminals, the lead-out terminals being exposed outside the housing of the relay; and

[0009] A connecting piece, which is electrically connected to the conductive base and the lead-out terminal.

[0010] In this relay design, a conductive base is installed inside the relay housing and electrically connected to the stationary contact. Then, connecting pieces are used to electrically connect the leads to the conductive base, thus achieving electrical connection between the leads and the stationary contact. Compared to the conventional design where the leads are directly connected to the stationary contact, in this application, the leads are first connected to the conductive base via connecting pieces, and then electrically connected to the stationary contact via the conductive base. This allows the conductive base and stationary contact to be pre-assembled, enabling the stationary contact to complete the connection process first, without being subjected to interference. The limitations imposed by the connection between the contact plate and the stationary contact improve the flexibility of relay manufacturing. On the other hand, when multiple leads need to be connected to the stationary contact simultaneously, traditional technology requires stacking multiple leads onto the stationary contact, which can easily cause the lead installation height to exceed the range. However, the conductive base in this application provides ample installation area, allowing different leads to be flexibly connected to different positions on the conductive base, avoiding the stacking of multiple leads and effectively solving the problem of excessive installation height, thus meeting the need for multiple leads to be connected to the stationary contact simultaneously.

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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] See Figure 1 This application illustrates a relay 100 in one embodiment, which can specifically be a high-voltage DC relay. Of course, in other optional embodiments, the relay 100 can also be a high-voltage AC relay, etc., and can be flexibly selected according to actual needs.

[0042] Please continue reading. Figure 1 For example, the relay 100 includes a stationary contact 10, a conductive base 20, a lead-out terminal 40, and a connecting piece 30. In addition, the relay 100 also includes a housing (not shown in the figure), which is the main component of the relay 100 and serves to directly or indirectly mount and fix the stationary contact 10, the conductive base 20, the lead-out terminal 40, and the connecting piece 30.

[0043] In this application, the conductive base 20 is disposed inside the housing of the relay 100 and is electrically connected to the stationary contact 10; the lead-out terminal 40 is exposed outside the housing of the relay 100; and the connecting piece 30 is electrically connected to the conductive base 20 and the lead-out terminal 40.

[0044] For example, the shell has a cuboid structure, thus having a top and bottom surface located at opposite ends along its length, and four side surfaces connecting the top and bottom surfaces. The lead-out end 40 is exposed outside the shell, which can be either exposed on the bottom surface of the shell, and / or exposed on the side surface of the shell, depending on the actual needs.

[0045] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the relay 100 of this solution, the conductive base 20 is installed inside the housing of the relay 100, and the conductive base 20 is electrically connected to the stationary contact 10. Then, the connecting piece 30 is used to electrically connect the lead-out terminal 40 to the conductive base 20, so as to realize the electrical connection between the lead-out terminal 40 and the stationary contact 10. Compared with the conventional technology in which the lead-out terminal 40 is directly connected to the stationary contact 10, in this application, the lead-out terminal 40 is first connected to the conductive base 20 through the connecting piece 30, and then indirectly electrically connected to the stationary contact 10 through the conductive base 20. On the one hand, the conductive base 20 and the stationary contact 10 can be pre-assembled together, so that the stationary contact 10 can be electrically connected to the stationary contact 10. The connection work is completed first, without being restricted by the connection between the connecting piece 30 and the stationary contact 10, thus improving the flexibility of the relay 100 production and processing. On the other hand, when multiple leads 40 need to be connected to the stationary contact 10 at the same time, the conventional technology requires multiple leads 40 to be stacked on the stationary contact 10, which easily causes the lead 40 to exceed the installation height range. However, in this application, the conductive base 20 provides ample installation area, allowing different leads 40 to be flexibly connected to different positions of the conductive base 20, avoiding the stacking of multiple leads 40, thereby effectively solving the problem of exceeding the installation height limit and meeting the need for multiple leads 40 to be connected to the stationary contact 10 at the same time.

[0046] Please continue reading. Figure 1 and Figure 2 In one embodiment, the conductive base 20 has a first side surface 211 and a second side surface 212 facing each other. The first side surface 211 is disposed facing the bottom surface of the housing, and the second side surface 212 is disposed facing the top surface of the housing. More specifically, the first side surface 211 and the second side surface 212 are two opposing sides in the thickness direction of the conductive base 20.

[0047] The stationary contact 10 is arranged on the side where the first side 211 is located, and the connecting piece 30 is mounted on the second side 212, so that the stationary contact 10 and the connecting piece 30 are arranged at intervals. In this way, the connecting piece 30 and the stationary contact 10 are respectively arranged on opposite sides of the conductive base 20, so that the connecting piece 30 and the conductive base 20 can avoid interference from the stationary contact 10 during installation; and the stationary contact 10 does not occupy the space of the second side 212, so that the second side 212 has a larger area to meet the installation needs of a larger number of connecting pieces 30.

[0048] Please continue reading. Figure 1 and Figure 2Furthermore, in an optional embodiment, the conductive base 20 is a conductive sheet connected to the stationary contact 10. Therefore, using a conductive sheet for the conductive base 20 results in a simple structure, occupies less housing space, and has low manufacturing cost. The surface of the conductive sheet is flat, allowing for better surface-to-surface contact with the connecting piece 30, thereby improving the reliability of the connection between the connecting piece 30 and the conductive sheet.

[0049] More specifically, the conductive sheet is a metal sheet. Metal sheets possess excellent electrical conductivity and sufficient structural strength. For example, the material of the metal sheet can be, but is not limited to, copper.

[0050] Please continue reading. Figure 1 and Figure 2 To further enhance the connection strength between the conductive base 20 and the stationary contact 10, based on the above embodiment, the relay 100 also includes a fastener 50. The conductive base 20 has a first mating portion, and the stationary contact 10 has a second mating portion. The fastener 50 is connected to both the first and second mating portions to connect the conductive base 20 and the stationary contact 10. The fastener 50's connection to both the first and second mating portions applies a tightening force to the conductive base 20 and the stationary contact 10, making the assembly of the conductive base 20 and the stationary contact 10 more secure.

[0051] Please continue reading. Figures 3 to 5 As an alternative to the embodiment where the conductive base 20 is a conductive sheet, in another optional embodiment, the conductive base 20 includes a first lead-out member 21, which is electrically connected to the stationary contact 10 and the connecting piece 30. The first lead-out member 21 has a first side 211 and a second side 212 opposite to each other. The stationary contact 10 is arranged on the side where the first side 211 is located, and the connecting piece 30 is mounted on the second side 212 so that the stationary contact 10 and the connecting piece 30 are arranged at intervals.

[0052] The conductive base 20 includes a first lead-out member 21, and the first lead-out member 21 is electrically connected to the stationary contact 10 and the connecting piece 30 respectively. At this time, the stationary contact 10 is located on the side where the first side 211 is located, while the connecting piece 30 is installed on the second side 212. This ensures that the installation of the connecting piece 30 and the first lead-out member 21 is not interfered with by the stationary contact 10, and also avoids the stationary contact 10 occupying the space of the second side 212. This allows the second side 212 to install a larger number of connecting pieces 30, meeting the installation requirements of assembling the stationary contact 10 with multiple leads 40.

[0053] Please continue reading. Figures 3 to 5Based on the above embodiments, in order to improve the connection strength between the first lead-out member 21 of the conductive base 20 and the stationary contact 10, the relay 100 further includes a fastener 50. The first lead-out member 21 is provided with a first mating part, and the stationary contact 10 is provided with a second mating part. The fastener 50 is connected to the first mating part and the second mating part to assemble and fix the first lead-out member 21 and the stationary contact 10. By using the fastener 50 to connect with the first mating part and the second mating part, a fastening force is applied to the first lead-out member 21 and the stationary contact 10, so that the conductive base 20 can be more firmly assembled with the stationary contact 10.

[0054] More specifically, based on any of the above embodiments, the fastener 50 is a threaded component, the first mating part is a through hole 213, and the second mating part is a threaded hole 11. The threaded component passes through the through hole 213 and is screwed into the threaded hole 11. This threaded connection method has a simple structure, and the installation and disassembly operations are convenient and labor-saving. In addition, the threaded pair has a self-locking characteristic, so even when the relay 100 is in a vibrating environment, the threaded component is not easy to loosen, which can reliably ensure that the conductive base 20 and the stationary contact 10 are connected and stable for a long time.

[0055] For example, the aforementioned threaded components can be any type of screw, bolt, etc., and can be flexibly selected according to actual needs. Furthermore, the stationary contact 10 and the conductive base 20 can be connected and fixed by more than one threaded component, and the actual number of threaded components used can be flexibly selected according to needs.

[0056] In the above embodiment, the threaded end of the threaded component protrudes from the second side 212. At this time, with the help of the tightening force of the threaded pair, the threaded end can be pressed against the conductive seat 20, so as to achieve the fastening installation of the conductive seat 20 and the stationary contact 10.

[0057] Please continue reading. Figures 3 to 5 The second side 212 includes a first region 2121 not obscured by the threaded head and a second region 2122 obscured by the threaded head. The connecting piece 30 is connected to the first region 2121, and the area of ​​the first region 2121 is larger than the surface area of ​​the side of the connecting piece 30 used for connecting to the first region 2121. Therefore, the first region 2121 provides a larger installation area, which can meet the installation needs of two or more connecting pieces 30, thereby enabling two or more leads 40 to be assembled with the stationary contact 10 through the conductive base 20.

[0058] Please continue reading. Figures 3 to 5Furthermore, based on the above embodiments, the conductive base 20 also includes a lead-out body 22, a second lead-out member 23, and a load connection end 24. One end of the lead-out body 22 is connected to the first lead-out member 21, and the other end of the lead-out body 22 is connected to the second lead-out member 23. The load connection end 24 is assembled and fixed with the second lead-out member 23. The load connection end 24 and the stationary contact 10 are respectively located on different surfaces of the relay 100.

[0059] That is, the overall connection structure of the first lead-out member 21, the lead-out body 22 and the second lead-out member 23 constitutes the conductive base 20, so that the stationary contact 10 can be electrically connected to the load connection terminal 24 through the conductive base 20, so as to obtain the effect of the stationary contact 10 being led out to different surfaces on the housing through the conductive base 20 and the load connection terminal 24, thereby improving the flexibility of the relay 100 installation.

[0060] For example, the first lead-out member 21, the lead-out body 22, and the second lead-out member 23 can cooperate to form any one of the following structures: a U-shaped structure, a C-shaped structure, etc. That is to say, the conductive base 20 has a U-shaped, C-shaped, or other structure. In this case, the conductive base 20 not only satisfies the requirement that the lead-out end 40 is electrically connected to the stationary contact 10 through it, but also satisfies the dual requirement that the stationary contact 10 is led out to other surfaces of the housing so as to be connected to an external load through the load connection end 24.

[0061] The lead-out body 22 can be installed inside the housing cavity, in a pre-designed installation channel inside the housing wall, or on the outer wall of the housing; the choice depends on the specific needs. However, it should be noted that to ensure the safe use of the relay 100, when the lead-out body 22 is exposed outside the housing, it must be wrapped with an insulating protective piece to provide insulation and prevent scratches that could affect its electrical conductivity and service life.

[0062] Please continue reading. Figure 1 and Figure 5 In one optional embodiment of this application, the lead-out terminal 40 includes a first mounting body 41 and a second mounting body 42. One end of the first mounting body 41 is connected to the connecting piece 30, and the second mounting body 42 is connected to the other end of the first mounting body 41. The second mounting body 42 is exposed on the outer surface of the housing of the relay 100. Therefore, the second mounting body 42 can be connected to the connecting piece 30 through the first mounting body 41, that is, the lead-out terminal 40 is electrically connected to the conductive base 20 and the stationary contact 10 through the connecting piece 30. The second mounting body 42 exposed on the housing facilitates connection between the relay 100 and external devices.

[0063] Optionally, the connection method between the second mounting body 42 and the external device can be, but is not limited to, welding, screwing, snap-fitting, etc., and can be flexibly selected according to actual needs.

[0064] Optionally, lead 40 includes a coil lead for supplying power to a coil mounted within the housing. Alternatively, lead 40 includes a detection lead for detecting the closure status of relay 100.

[0065] It should be noted that the lead 40 can be used alone or in pairs. When two leads 40 are used in pairs, one lead 40 is used as the positive terminal connection and the other lead 40 is used as the negative terminal connection.

[0066] Furthermore, based on the above embodiments, the second mounting body 42 and the stationary contact 10 are arranged on the same surface of the relay 100 housing. This eliminates the need to reverse the spatial orientation of the relay 100, facilitating connection of the second mounting body 42 and the stationary contact 10 to external devices or loads and improving the ease of use of the relay 100.

[0067] For example, in this application, both the second mounting body 42 and the stationary contact 10 are exposed on the top surface of the housing.

[0068] Please continue reading. Figure 3 In one embodiment, the relay 100 further includes a mounting base 60, with the lead-out end 40 disposed in the mounting base 60. The mounting base 60 has a clearance through hole 61, which is disposed opposite to the stationary contact 10, so that the stationary contact 10 is exposed through the clearance through hole 61. By providing the mounting base 60 and mounting the lead-out end 40 in the mounting base 60, the mounting base 60 can support and fix the lead-out end 40, preventing the lead-out end 40 from shaking during the transportation and use of the relay 100, thus affecting the connection stability. In addition, the mounting base 60 at least partially encloses the lead-out end 40, which also forms an insulation and protection effect.

[0069] Please continue reading. Figure 1 and Figure 5 Furthermore, in one embodiment, the first mounting body 41 is formed as a bent structure to increase the distance between the first mounting body 41 and the conductive base 20. Specifically, the first mounting body 41 has multiple bent segments, which causes the first mounting body 41 to gradually extend away from the conductive base 20 after installation, so that a sufficiently large distance is formed between the first mounting body 41 and the conductive base 20. On the one hand, this distance can form a safe distance between the first mounting body 41 and the conductive base 20 to avoid phenomena such as electric arcing due to excessive close proximity; on the other hand, increasing the distance between the first mounting body 41 and the conductive base 20 can also free up sufficient space so that the connecting piece 30 and the first mounting body 41 can be wrapped by the fixing base 60.

[0070] More specifically, the lead-out end 40 and the fixing base 60 are integrally formed. The lead-out end 40 and the fixing base 60 are connected and fixed by an integral molding process, which simplifies the processing, provides good connection strength and stability between the lead-out end 40 and the fixing base 60, and allows the lead-out end 40 to be pre-connected to the fixing base 60 as an integral structure, so that both can be installed to the conductive base 20 at the same time through the connecting piece 30, saving installation steps and improving production efficiency.

[0071] For example, the fixing base 60 is made of plastic, and the lead-out end 40 and the fixing base 60 are integrally injection molded using an injection mold.

[0072] 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.

[0073] 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.
