Description

Technical Field

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

[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, traditional electromagnet core assemblies suffer from low assembly efficiency and poor structural stability. Specifically: the step-by-step assembly of the yoke frame and the separate installation of the wire frame result in cumbersome and time-consuming processes; multi-directional operations and manual positioning increase assembly difficulty and errors; the lack of internal support during riveting causes frame deformation and wire frame misalignment; and the absence of an interlocking mechanism between the wire frame and the yoke results in insufficient vibration resistance of the assembly. Therefore, there is an urgent need to develop a new type of assembly and process that enables synchronized, unidirectional assembly, achieves component self-positioning, and utilizes the synergistic deformation resistance and bi-directional reinforcement of the wire frame and yoke to improve efficiency and reliability. Summary of the Invention

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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 Y direction shown in the figures; the second direction in this application can be understood as the X direction shown in the figures; and the third direction in this application can be understood as the Z direction shown in the figures.

[0048] See Figure 1As shown, the electromagnet core assembly 1000 according to this application includes a yoke 100 and two wire frames 200. The yoke 100 includes two first yoke bodies 11 and two second yoke bodies 12. The two first yoke bodies 11 are spaced apart along the width direction of the yoke 100, and the two second yoke bodies 12 are connected between the two first yoke bodies 11. The two second yoke bodies 12 are spaced apart along the length direction of the yoke 100, thereby defining a magnetic circuit space 101 within the yoke 100. The two wire frames 200 are disposed within the magnetic circuit space 101 defined by the yoke 100. The first yoke bodies 11 are provided with two sets of first insertion portions. In the length direction of the first yoke bodies 11 (i.e., the length direction of the yoke 100), the two sets of first insertion portions are located between two sets of first rivet holes, and the two sets of first insertion portions are arranged sequentially in the length direction of the first yoke bodies 11. Each wire frame 200 is also provided with two sets of second plug-in portions. In the width direction of the wire frame 200, the two sets of second plug-in portions are located on both sides of the wire frame 200 (that is, one set of second plug-in portions is located on the left side of the wire frame 200, and the other set of second plug-in portions is located on the right side of the wire frame 200). The second plug-in portions respectively provided on both sides of the wire frame 200 are plugged into the first plug-in portions in the two first yoke bodies 11, so that the wire frame 200 is assembled in the magnetic circuit space 101 of the yoke body 100.

[0049] Therefore, for the electromagnet core assembly 1000 of this application, during the assembly process, the operator only needs to move the two first yoke bodies 11 towards each other along the width direction of the electromagnet core assembly 1000 to simultaneously achieve the following key actions: all second yoke bodies 12 are riveted and fixed to the first yoke bodies through first rivet heads arranged in the width direction; at the same time, all wire frames 200 are precisely inserted into the first insertion parts of the first yoke bodies 11 on both sides through second insertion parts symmetrically arranged in the width direction. This design completes the assembly of the electromagnet core assembly 1000 in one go through synchronous assembly actions in a single direction, significantly shortening the assembly time of the electromagnet core assembly 1000 and avoiding the cumbersome nature of traditional multi-step, multi-directional operations.

[0050] It should also be noted that during the pre-assembly of the first yoke 11 and the second yoke 12, the operator can achieve the positioning and assembly of the first yoke 11 and the second yoke 12 through the corresponding mating first riveting hole 111 and first riveting head 120. This eliminates the need for the operator to calibrate the assembly position of the first yoke 11 and the second yoke 12 during the assembly process, thereby facilitating the rapid assembly of the yoke 100 and improving the assembly efficiency of the electromagnet core assembly 1000. The first yoke 11 is provided with a first riveting hole, and the second yoke 12 is provided with a first riveting head, enabling the first yoke 11 and the second yoke 12 to be riveted together. This gives the yoke 100 high stability, thereby improving the reliability of the yoke 100 in use. Furthermore, since the wire frame 200 is placed within the magnetic circuit space 101, when the first yoke 11 and the second yoke 12 are fixed by riveting, the wire frame 200 can resist the lateral compression deformation tendency of the second yoke 12 on the first yoke 11 during riveting, and at the same time provide a bidirectional reinforcement mechanism for the wire frame 200. This not only improves assembly efficiency but also significantly enhances the structural rigidity and stability of the electromagnet core assembly 1000.

[0051] In summary, the electromagnet core assembly 1000 of this application achieves significant efficient assembly and structural reinforcement through the ingenious cooperation between the yoke 100 (which defines the magnetic circuit space 101 by two spaced-apart first yoke bodies 11 and two connected second yoke bodies 12) and the two wire frames 200 placed in the magnetic circuit space 101.

[0052] See Figures 1 to 4 As shown, in some embodiments of this application, the first yoke 11 has two first rivet holes, which are spaced apart along the length of the first yoke 11. In the width direction of the second yoke 12, protruding first rivet heads are respectively provided on both sides of the second yoke 12, and the first rivet heads are adapted to be riveted into the first rivet holes. Thus, the two first yokes 11 and the two second yokes 12 are riveted together to form the yoke 100. Specifically, the first rivet holes include at least one first rivet hole 111, and the first rivet heads include at least one first rivet head 120, with each first rivet hole 111 corresponding to and riveting into each first rivet head 120. In other words, the number of first riveting holes 111 in the first riveting hole portion is configured to be the same as the number of first riveting joints 120 in the corresponding first riveting head. Thus, for the corresponding first riveting hole portion and first riveting head, each first riveting hole 111 and each first riveting joint 120 are riveted together in a one-to-one correspondence.

[0053] For example, combining Figures 1 to 4As shown, the number of first riveting holes 111 in each first riveting section is configured to be two, and the number of first riveting joints 120 in each first riveting head is correspondingly configured to be two. Thus, after the first yoke body 11 and the second yoke body 12 are assembled, two connection points are formed between the first yoke body 11 and the second yoke body 12 (one first riveting joint 120 is riveted to one first riveting hole 111 to form a connection point). Based on this, the number of first riveting holes 111 in the first riveting section is configured to be multiple, and the number of first riveting joints 120 in the first riveting head is configured to be multiple, so that multiple connection points are formed between the first yoke body 11 and the second yoke body 12, so that the connected first yoke body 11 and the second yoke body 12 have high connection reliability, which is beneficial to improving the overall structural stability of the yoke 100.

[0054] Of course, this application is not limited to this. For example, the number of first riveting holes 111 in each first riveting hole portion can also be configured to one, three, four or five, etc., and the number of first riveting heads 120 in each first riveting head can also be configured to one, three, four or five, etc.

[0055] It is important to understand that during the assembly of the first yoke 11 and the second yoke 12, the operator needs to insert the first rivet joint 120 into the corresponding first rivet hole 111 to achieve pre-assembly of the first yoke 11 and the second yoke 12. Thus, during the pre-assembly of the first yoke 11 and the second yoke 12, the operator can achieve the positioning and assembly of the first yoke 11 and the second yoke 12 through the corresponding mating first rivet hole 111 and first rivet joint 120. This eliminates the need for the operator to calibrate the assembly position of the first yoke 11 and the second yoke 12 during the assembly process, thereby facilitating the rapid assembly of the yoke 100 and improving the assembly efficiency of the electromagnet core assembly 1000.

[0056] Furthermore, after the corresponding first riveting hole 111 and first riveting head 120 are riveted together, the first riveting head 120 is located inside the first riveting hole 111, and the outer peripheral wall of the first riveting head 120 is in contact with the inner peripheral wall of the first riveting hole 111, thereby limiting the mutual positioning of the first yoke body 11 and the second yoke body 12. In other words, after the first yoke body 11 and the second yoke body 12 are riveted together, the first riveting head 120 cannot move within the first riveting hole 111, thus achieving the effect of limiting the mutual positioning of the first yoke body 11 and the second yoke body 12. Specifically, the connected first yoke body 11 and the second yoke body 12 mutually limit each other in three dimensions: length, width, and height, giving the connected first yoke body 11 and the second yoke body 12 high connection reliability, which in turn helps to improve the overall structural stability of the yoke 100.

[0057] Combination Figures 1 to 4 As shown, in some embodiments of this application, when the number of first riveting holes 111 in the first riveting portion is configured to be multiple, the multiple first riveting holes 111 are arranged sequentially in the height direction of the first yoke 11, and adjacent first riveting holes 111 are spaced apart. When the number of first riveting joints 120 in the first riveting head is configured to be multiple, the multiple first riveting joints 120 are arranged sequentially in the height direction of the second yoke 12, and adjacent first riveting joints 120 are spaced apart. In this way, relative torsion of the connected first yoke 11 and second yoke 12 is avoided to a certain extent, thereby improving the connection stability of the connected first yoke 11 and second yoke 12, and thus helping to improve the overall structural stability of the yoke 100.

[0058] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this application, a plurality of first riveting holes 111 are arranged sequentially in the height direction of the first yoke 11, and all the first riveting holes 111 are arranged in a straight line. Correspondingly, a plurality of first rivet joints 120 are arranged sequentially in the height direction of the second yoke 12, and all the first rivet joints 120 are arranged in a straight line. This makes the thickness of the second yoke 12 smaller. Of course, this application is not limited to this. For example, for the plurality of first rivet joints 120 arranged sequentially in the height direction of the second yoke 12, two adjacent first rivet joints 120 are staggered in the thickness direction of the second yoke 12. Correspondingly, for the plurality of first rivet joints 120 arranged sequentially in the height direction of the first yoke 11, two adjacent first riveting holes 111 are staggered in the length direction of the first yoke 11.

[0059] See Figure 3 As shown, in some embodiments of this application, the first riveting hole 111 includes a first inner hole 111a and at least one first embedded structure 111b. The first embedded structure 111b protrudes outward from the edge of the first inner hole 111a and communicates with the first inner hole 111a. It should be understood that, referring to... Figure 3 As shown, in one embodiment, the first inner hole 111a is constructed as a through hole, and the first embedded structure 111b is constructed as a through hole, so that the first riveting hole 111 is constructed as a through hole as a whole. Alternatively, in another embodiment, the first inner hole 111a is constructed as a through hole, and the first embedded structure 111b is constructed as a groove, so that the first riveting hole 111 is constructed as a countersunk hole as a whole.

[0060] When the first rivet joint 120 is riveted into the first rivet hole 111, for the deformed first rivet hole 111, part of the structure of the first rivet hole 111 is embedded into the first embedded structure 111b through deformation, which increases the difficulty for the first rivet joint 120 to rotate relative to the first yoke 11 in the direction about the axis of the first rivet hole 111. In this way, relative torsional twisting of the connected first yoke 11 and second yoke 12 is avoided to a certain extent, thereby improving the connection stability of the connected first yoke 11 and second yoke 12, and thus helping to improve the overall structural stability of the yoke 100.

[0061] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, in the width direction of the yoke 100, the outer surface of the first yoke body 11 is provided with a first snap-fit ​​portion 113. The first snap-fit ​​portion 113 is used to snap-fit ​​with a second snap-fit ​​portion of the relay housing (not shown in the figure), so that the yoke 100 can be assembled to the relay housing by snap-fit ​​assembly. For example, in conjunction with... Figure 1 and Figure 2 As shown, in some embodiments of this application, the first latching portion 113 is constructed as a latching protrusion, and the second latching portion of the relay housing is constructed as a latching groove, thus making the first latching portion 113 suitable for latching with the second latching portion. Alternatively, in another embodiment, the first latching portion 113 is constructed as a latching groove, and the second latching portion of the relay housing is constructed as a latching protrusion, which also allows the first latching portion 113 to be suitable for latching with the second latching portion.

[0062] Additionally, for example, the first yoke body 11 is provided with a plurality of first latching portions 113, and the relay housing is also provided with a plurality of second latching portions accordingly. Each of the plurality of first latching portions 113 is constructed as either a latching protrusion or a latching groove, and correspondingly, each of the plurality of second latching portions is constructed as either a latching protrusion or a latching groove. Alternatively, a portion of the plurality of first latching portions 113 may be constructed as a latching protrusion, and another portion as a latching groove; similarly, a portion of the plurality of second latching portions may be constructed as a latching groove, and another portion as a latching protrusion.

[0063] Combination Figure 1 and Figure 4 As shown, in some embodiments of this application, a third snap-fit ​​portion 121 is provided on the outer surface of the second yoke body 12 along the length direction of the yoke 100. The third snap-fit ​​portion 121 is used to snap-fit ​​with a fourth snap-fit ​​portion of the relay housing (not shown in the figure), so that the yoke 100 can be assembled to the relay housing by snap-fit ​​assembly. For example, in conjunction with... Figure 1 and Figure 4As shown, in some embodiments of this application, the third latching portion 121 is constructed as a latching protrusion, and the fourth latching portion of the relay housing is constructed as a latching groove, thus making the third latching portion 121 suitable for latching with the fourth latching portion. Alternatively, in another embodiment, the third latching portion 121 is constructed as a latching groove, and the fourth latching portion of the relay housing is constructed as a latching protrusion, which also allows the third latching portion 121 to be suitable for latching with the fourth latching portion.

[0064] Additionally, for example, the second yoke 12 is provided with a plurality of third engaging portions 121, and the relay housing is also provided with a plurality of fourth engaging portions accordingly. Each of the plurality of third engaging portions 121 is constructed as either a engaging protrusion or a engaging groove, and correspondingly, each of the plurality of fourth engaging portions is constructed as either a engaging protrusion or a engaging groove. Alternatively, some of the plurality of third engaging portions 121 may be constructed as engaging protrusions, and others as engaging grooves; similarly, some of the plurality of fourth engaging portions may be constructed as engaging grooves, and others as engaging protrusions.

[0065] Combination Figures 1 to 3 As shown, in some embodiments of this application, in the height direction of the yoke 100, the upper boundary of the second yoke body 12 is lower than the upper boundary of the first yoke body 11, and the lower boundary of the second yoke body 12 is higher than the lower boundary of the first yoke body 11. In other words, in the height direction of the yoke 100, both the upper and lower ends of the second yoke body 12 are located inside the first yoke body 11. Similarly, the upper boundary of the wire frame 200 is lower than the upper boundary of the first yoke body 11, and the lower boundary of the wire frame 200 is higher than the lower boundary of the first yoke body 11. In other words, in the height direction of the yoke 100, both the upper and lower ends of the wire frame 200 are located inside the first yoke body 11. Furthermore, in the height direction of the first yoke 11, the first yoke 11 has a concave region 114 that is recessed upward from the lower boundary of the first yoke 11, such that the lower end of the first yoke 11 has at least two abutting feet 115, and the concave region 114 is located between two adjacent abutting feet 115 in the length direction of the first yoke 11.

[0066] This not only reduces the contact area between the lower end of the first yoke 11 and the relay housing, but also reduces the mass of the first yoke 11 (i.e., the concave region 114 reduces the weight of the first yoke 11). It is important to understand that when the electromagnet core assembly 1000 is assembled inside the relay housing, the lower end of the electromagnet core assembly 1000 only contacts the relay housing through the abutment feet 115 of the first yoke 11, resulting in a small contact area between the electromagnet core assembly 1000 and the relay housing. Furthermore, because the contact area between the electromagnet core assembly 1000 and the relay housing is small, the risk of the yoke 100 tilting relative to the horizontal plane due to unevenness of the relay housing surface is reduced. In other words, this design allows the electromagnet core assembly 1000 to be placed horizontally when assembled inside the relay housing.

[0067] Combination Figure 1 and Figure 2 ,as well as Figure 5 and Figure 6 As shown, in some embodiments of this application, the wire frame 200 includes two wire frame end plates 21 and a wire frame cylinder 22. The two wire frame end plates 21 are respectively disposed at both ends of the wire frame cylinder 22, and the coil is sleeved on the wire frame cylinder 22. See also... Figure 5 As shown, in the width direction of the wire frame end plate 21, at least one second plug-in structure 211 is provided on each side of the wire frame end plate 21. All the second plug-in structures 211 located on the same side in the width direction of each wire frame 200 constitute a group of second plug-in portions. And combined with... Figures 1 to 3 As shown, each first yoke body 11 is also provided with two sets of first plug-in parts, and each set of first plug-in parts includes at least one first plug-in structure 112, and the first plug-in structure 112 and the second plug-in structure 211 are plugged in and engaged in a one-to-one correspondence.

[0068] In some embodiments of this application, one of the first insertion structure 112 and the second insertion structure 211 is configured as a insertion post, and the other of the first insertion structure 112 and the second insertion structure 211 is configured as a insertion hole, with the insertion post and the insertion hole engaging. In other words, when the first insertion structure 112 disposed on the first yoke 11 is configured as a insertion post, the second insertion structure 211 disposed on the wire frame 200 is correspondingly configured as a insertion hole, so that the first insertion structure 112 (insertion post) and the second insertion structure 211 (insertion hole) engage, achieving the effect of assembling the wire frame 200 onto the yoke 100. Alternatively, when the first insertion structure 112 disposed on the first yoke 11 is configured as a insertion hole, the second insertion structure 211 disposed on the wire frame 200 is correspondingly configured as a insertion post.

[0069] See Figure 3 and Figure 6 As shown, in some embodiments of this application, the first insertion structure 112 is configured as an insertion hole, and the second insertion structure 211 is configured as an insertion post. The first insertion structure 112 (insertion hole) has a length dimension of D1, and the second insertion structure 211 (insertion post) has a length dimension of E1, satisfying the relationship: D1 > E1; and the first insertion structure 112 has a height dimension of D2, and the second insertion structure 211 has a height dimension of E2, satisfying the relationship: D2 = E2. Therefore, the wire frame 200 can move relative to the yoke 100 in the length direction, so as to facilitate the adjustment of the relative position of the wire frame 200 relative to the yoke 100 in the length direction during the assembly of the electromagnet core assembly 1000 into the relay housing; and the wire frame 200 cannot move relative to the yoke 100 in the height direction, ensuring that the upper and lower ends of the wire frame 200 are both located inside the first yoke body 11, thereby ensuring that when the electromagnet core assembly 1000 is assembled into the relay housing, the lower end of the electromagnet core assembly 1000 only contacts the relay housing through the abutment support 115 of the first yoke body 11.

[0070] See Figures 5 to 7 As shown, in some embodiments of this application, the two end plates 21 of the wire frame 200 are a first end plate 2101 and a second end plate 2102, respectively. The first end plate 2101 is provided with a mounting portion 212, which protrudes outward in the thickness direction of the first end plate 2101, and at least one insertion hole 2120 is provided within the mounting portion 212, extending along the thickness direction of the first end plate 2101. The insertion hole 2120 is used to pass through the lead conductor 300 of the coil, so that the mounting portion 212 can fix and assemble the lead conductor 300.

[0071] In some embodiments of this application, the mounting portion 212 abuts against and limits the adjacent second yoke body 12. Exemplarily, in conjunction with... Figure 1 and Figure 6 As shown, in some embodiments of this application, along the length of the electromagnet core assembly 1000, in the two wire frames 200 of the electromagnet core assembly 1000, the mounting portion 212 of the first end plate 2101 of the wire frame 200 located on the front side is located on the upper side of the adjacent second yoke 12, and the mounting portion 212 abuts and limits the second yoke 12 in the height direction. In this way, the second yoke 12 provides support for the wire frame 200 in the height direction.

[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.
