[0002] Relays, as control components, are driving devices that use small current to control large current, and are widely used in aerospace, automotive, home appliances, industrial control, and other fields. In recent years, with the rapid development of the Internet, Internet data centers are crucial for supporting Internet services. Magnetic latching relays are typically used in their power supply circuits for power switching control. To ensure that in the event of a main power failure, the relay can quickly switch to a backup power supply upon receiving a control signal, thus minimizing losses from the failure.

[0003] In related technologies, the coil frame structure in relays generally adopts an integrated single-unit design. That is, the coil winding and the terminal block (or wiring conductor) are all mounted and fixed on a single coil frame structure.

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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the first direction in this application can be understood as the X direction shown in the figures; the second direction in this application can be understood as the Y direction shown in the figures; and the third direction in this application can be understood as the Z direction shown in the figures.

[0047] See Figures 1 to 3 As shown, the wire frame assembly according to this application includes two wire frames 1 and two sets of wiring assemblies 2, with each wire frame 1 having one set of wiring assemblies 2. In the longitudinal direction (i.e., the first direction) of the wire frame assembly, the two wire frames 1 are arranged at intervals, and each wire frame 1 has a moving channel 130, with the two moving channels 130 in a connected state. Thus, in the longitudinal direction of the wire frame assembly, the moving channels 130 of the two wire frames 1 and a portion of the space between the two wire frames 1 together constitute a moving space, which is used to accommodate the moving magnetic body 200 of the relay, allowing the moving magnetic body 200 to be movably assembled within the moving space. In other words, this allows the moving magnetic body 200 to be movably assembled between the two wire frames 1, and the moving magnetic body 200 can move relative to these two wire frames 1. It should be further noted that when the moving magnetic body 200 is assembled within the wire frame assembly (i.e., when the moving magnetic body 200 is assembled between the two wire frames 1), the moving magnetic body 200 must simultaneously be located within both moving channels 130.

[0048] Each wiring assembly 2 includes at least two wiring guides 21. The wiring guides 21 extend along the length direction of the wire frame assembly (which can also be understood as the length direction of the wire frame 1), and the multiple wiring guides 21 in the wiring assembly 2 are arranged at intervals along the width direction of the wire frame assembly (i.e., the second direction, which can also be understood as the width direction of the wire frame 1). Furthermore, in the length direction of the wire frame assembly, adjacent wiring guides 21 are connected end-to-end. In other words, the tail of the wiring guide 21 located at the front is connected to the front of the wiring guide 21 located at the rear, achieving the effect of conductive connection between adjacent wiring guides 21.

[0049] For example, in combination Figure 1 and Figure 3 As shown, the process of assembling the movable magnet 200 into the wire frame assembly is as follows: First, two independent wire frames 1 are pre-prepared, and each set of wiring assemblies 2 (containing at least two wiring conductors 21 connected end-to-end in the length direction and spaced apart in the width direction) has been installed and fixed on the corresponding wire frame 1. At this time, the two wire frames 1 are in a separated state, and the wiring assemblies 2 on them are independent of each other and have not yet been connected. The operator initially positions the movable magnet 200 so that it is aligned with the movement channel 130 of one of the wire frames 1. Then, the movable magnet 200 is inserted into its movement channel 130 along the length direction (first direction) of the wire frame 1, so that a portion of the movable magnet 200 is accommodated therein.

[0050] Then, the moving channel 130 of another wire frame 1 is aligned with the moving magnetic body 200, and the two wire frames 1 are gradually brought closer together in the longitudinal direction, ensuring that the designed interval distance is maintained between the two wire frames 1. During this process, the portion of the moving magnetic body 200 located outside one wire frame 1 moves into the moving channel 130 of the other wire frame 1. When the two wire frames 1 are assembled in place and maintain a fixed interval, the moving channels 130 of the two wire frames 1 and part of the space between the two wire frames 1 are connected, forming a complete moving space. At this time, the moving magnetic body 200 is completely accommodated in this moving space and can slide in the moving space along the longitudinal direction, realizing movable assembly relative to the two wire frames 1.

[0051] After confirming that the moving magnetic conductor 200 is correctly assembled in the moving space consisting of two wire frames 1, the wiring assemblies 2 located on the two adjacent wire frames 1 are finally connected.

[0052] In summary, the wireframe assembly according to this application includes two wireframes 1 and two sets of wiring assemblies 2. Each wireframe 1 is provided with one set of wiring assemblies 2, wherein each wiring assembly 2 includes at least two wiring conductors 21, and two adjacent wiring conductors 21 are connected end to end along the length direction. This allows the wireframe assembly according to this application to adopt a split design, which not only simplifies the structure of the wireframe assembly to the greatest extent possible, thereby reducing product complexity, but also directly brings a series of core advantages such as improved production efficiency, reduced costs, more controllable quality, and more convenient maintenance, meeting the demands of modern relays for high performance, high reliability, and low-cost manufacturing.

[0053] See Figures 1 to 7 As shown in some embodiments of this application, two adjacent wiring conductors 21 along the length of the wireframe assembly have a connector 3 at one end. The connector 3 is used to connect to the other wiring conductor 21, thereby achieving the effect of connecting two adjacent wiring conductors 21 along the length of the wireframe assembly. The connector 3 includes a fitting section 31 and a misaligned section 32. The fitting section 31 is parallel to the wiring conductor 21 to which the connector 3 is connected, and the misaligned section 32 connects between the wiring conductor 21 and the fitting section 31. The fitting section 31 is also fitted to the side surface of the other wiring conductor 21. This achieves the effect of connecting two adjacent wiring conductors 21 along the length of the wireframe assembly. This significantly increases the effective contact area and welding area between the two adjacent wiring conductors 21. This not only greatly improves the mechanical strength and reliability of the welded connection and reduces the risk of incomplete soldering and desoldering, but also provides a larger conductive cross-sectional area, ensuring the stability and low impedance of current conduction between adjacent wiring conductors 21, thereby ultimately improving the electrical performance and long-term operational reliability of the relay.

[0054] See Figures 1 to 7 As shown, in some embodiments of this application, a connector 3 is provided at the same end of all the wiring conductors 21 in the wiring assembly 2. Among the multiple connectors 3 connected to the same wiring assembly 2, the mating sections 31 of two adjacent connectors 3 are located on both sides of the wiring conductor 21 to which they are connected, or the mating sections 31 of two adjacent connectors 3 are located on the same side of the wiring conductor 21 to which they are connected.

[0055] Exemplary examples, in some embodiments of this application, combined with Figures 1 to 3As shown, in the width direction, the mating section 31 of the connecting body 3 of the wiring guide 21 connected to the left side is located on the right side of the wiring guide 21, and the mating section 31 of the connecting body 3 of the wiring guide 21 connected to the right side is located on the left side of the wiring guide 21 (that is, the mating sections 31 of two adjacent connecting bodies 3 are located on both sides of the wiring guide 21 to which they are connected). In this way, the mating sections 31 connected to two adjacent wiring guides 21 form a "plug", and the tail ends of the two mating wiring guides 21 form a "socket", which makes the mating of the wiring assemblies 2 respectively set on the two wire frames 1 more accurate.

[0056] In some embodiments of this application, combined with Figure 1 and Figure 4 As shown, in the width direction, the mating section 31 of the connecting body 3 of the wiring guide 21 connected to the left side is located on the left side of the wiring guide 21, and the mating section 31 of the connecting body 3 of the wiring guide 21 connected to the right side is located on the right side of the wiring guide 21 (that is, the mating sections 31 of two adjacent connecting bodies 3 are located on both sides of the wiring guide 21 to which they are connected). In this way, the mating sections 31 connected to two adjacent wiring guides 21 form a "socket", and the tail ends of the two mating wiring guides 21 form a "plug", which makes the mating of the wiring assemblies 2 respectively set on the two wire frames 1 more accurate.

[0057] In addition, combined Figure 1 and Figure 5 As shown, in the width direction, the mating section 31 in the connecting body 3 of the wiring guide 21 connected to the left side is located on the right side of the wiring guide 21, and the mating section 31 in the connecting body 3 of the wiring guide 21 connected to the right side is located on the right side of the wiring guide 21 (that is, the mating sections 31 of two adjacent connecting bodies 3 are located on the same side of the wiring guide 21 to which they are connected).

[0058] It should also be noted that in some of the above embodiments, the relative positional relationship between the mating segment 31 and the connected wiring conductor 21 in the width direction is used as an example for illustration, but this application is not limited to this. For example, in conjunction with Figure 1 and Figure 6 As shown, the relative positional relationship between the mating section 31 and the wiring conductor 21 to which it is connected can be referenced in the height direction (i.e., the Z direction shown in the figure).

[0059] See Figure 7 As shown, in some embodiments of this application, the misaligned segment 32 is vertically connected between the wiring guide 21 and the fitting segment 31, and the end of the other wiring guide 21 abuts against the misaligned segment 32 for limitation. When the two wire frames 1 are assembled in place along the length direction of the wire frame assembly, the end of the other wiring guide 21 abuts against the outer surface of the misaligned segment 32.

[0060] For example, in combination Figure 1 and Figure 7 As shown, connector 3 is connected to the front end of the rear wiring guide 21. During the assembly of the two wire frames 1, the mating section 31 of the rear wiring guide 21 is positioned to mate with the side surface of the front wiring guide 21. Simultaneously, the rear end face of the front wiring guide 21 abuts against the front side face of the misalignment section 32. This abutment relationship prevents the two wiring guides 21 from continuing to move relative to each other along the length of the wire frame assembly. By limiting excessive displacement through end abutment, a stable physical positioning reference is provided for subsequent welding operations.

[0061] In some embodiments of this application, the wiring conductor 21 and the connector 3 are integrally formed. For example, the wiring conductor 21 and the connector 3 are integrally formed by processes such as metal stamping or bending, or by casting. Integral forming eliminates the physical interface between the wiring conductor 21 and the connector 3, while ensuring the overall structural reliability of the wiring conductor 21 and the connector 3, and eliminating the risk of breakage at the connection point between the wiring conductor 21 and the connector 3.

[0062] See Figure 1 and Figure 3 As shown, in some embodiments of this application, the wire frame 1 includes a first end plate 11, a second end plate 12, and a wire frame cylinder 13. The first end plate 11 and the second end plate 12 are respectively disposed at both ends of the wire frame cylinder 13. The first end plate 11 is provided with at least two insertion holes 110, which are adapted to pass through the wiring guide 21, so that the wiring guide 21 is inserted and assembled into the wire frame 1. The outside of the wire frame cylinder 13 is used to house coils, which are connected to the wiring guide 21. A moving channel 130 is defined inside the wire frame cylinder 13 to allow the movable magnetic conductor 200 to move relative to the two wire frames 1. Specifically, as shown... Figure 1 As shown, in the height direction of the wire frame 1, the position of the insertion hole 110 provided on the first end plate 11 is higher than the outer surface of the wire frame cylinder 13 and has a certain distance, so as to avoid the wiring conductor 21 from contacting the outer peripheral surface of the coil.

[0063] See Figures 1 to 3 As shown, in some embodiments of this application, in two adjacent wire frames 1, the second end plate 12 between two adjacent first end plates 11 abuts against the wiring assembly 2 in the height direction of the wire frame 1. That is, the second end plate 12 provides upward support to the wiring assembly 2 in the height direction, thereby improving the structural stability of the wiring assembly 2. For example, see [reference needed]. Figure 1 As shown, the second end plate 12 of the wire frame 1 located on the front side is supported under the wiring assembly 2 located on the rear side, thereby avoiding the downward deformation of the wiring conductor 21 in the wiring assembly 2 to a certain extent, ensuring the structural stability of the wiring conductor 21, and thus improving the connection reliability between the two connected wiring conductors 21.

[0064] See Figure 1 As shown, in some embodiments of this application, the wire frame assembly further includes an external wiring group 4, which includes at least two external wires 41. Each external wire 41 is connected one-to-one with the wiring guide 21 located at the first end, and the external wires 41 extend downward in the height direction. This is beneficial for the spatial arrangement of the relay when the wire frame assembly is applied to the relay.

[0065] 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.

[0066] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
