[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[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] like Figure 1 As shown in the figure, this embodiment provides a welding machine, which includes a welding machine body (not shown in the figure) and a signal connection line 500. The signal connection line 500 is connected to the welding machine body and is used to transmit signals.
[0048] To prevent interference with the signal transmitted by the signal connection cable 500, a magnetic ring 200 is fitted over the cable to form an inductive filter, reducing electromagnetic interference and high-frequency, high-voltage interference. However, during use, the magnetic ring 200 on the signal connection cable 500 is prone to wobbling and difficult to fix, which can affect the reliability of the entire device.
[0049] To solve the above problems, such as Figures 1-3 As shown, the welding machine provided in this embodiment also includes a magnetic ring fixing device 100, which is mounted on the welding machine body. In this embodiment, the welding machine body includes an arc-starting plate fixing bracket 400, and the magnetic ring fixing device 100 is mounted on the arc-starting plate fixing bracket 400, which provides an installation position for the magnetic ring fixing device 100. In other embodiments, the magnetic ring fixing device 100 may also be mounted at other positions on the welding machine body.
[0050] Specifically, the magnetic ring fixing device 100 provided in this embodiment includes a fixing part 10, two clamping arms 20 arranged opposite each other along a horizontal first direction, and two limiting parts 30 arranged opposite each other along a vertical direction. The fixing part 10 is connected to the welding machine body. The clamping arms 20 are disposed on the fixing part 10, and the limiting parts 30 are disposed on the fixing part 10. The clamping arms 20, the limiting parts 30 and the fixing part 10 together form a clamping space 1001. The magnetic ring 200 is disposed in the clamping space 1001. Through the above arrangement, the magnetic ring 200 is fixed in the clamping space 1001, which effectively prevents the magnetic ring 200 from shaking and has good installation stability.
[0051] Optionally, the welding machine also includes a fastener 300. The magnetic ring fixing device 100 (specifically the fixing part 10) has a fixing hole 12. The fastener 300 passes through the fixing hole 12 and is connected to the welding machine body (specifically the arc-starting plate fixing bracket 400). Specifically, the fastener 300 can be a screw. After passing through the fixing part 10, the screw is threadedly connected to the arc-starting plate fixing bracket 400, which provides a stable connection and facilitates disassembly and assembly.
[0052] In this embodiment, a limiting hole 410 is provided on the arc-starting plate fixing bracket 400, and a limiting boss 11 is provided on the fixing part 10. The limiting boss 11 is inserted into the limiting hole 410 to restrict the magnetic ring fixing device 100 from rotating relative to the arc-starting plate fixing bracket 400. In other embodiments, the limiting hole 410 can also be provided on the fixing part 10, and the limiting boss 11 can be provided on the arc-starting plate fixing bracket 400, which can achieve the same effect. Specifically, the limiting hole 410 is a non-circular hole, and the limiting boss 11 is adapted to the limiting hole 410 to prevent the fixing part 10 from rotating relative to the arc-starting plate fixing bracket 400.
[0053] like Figure 4 As shown, the limiting part 30 includes a guide slope 31, and the magnetic ring 200 can be inserted into the clamping space 1001 along the guide slope 31 to facilitate the assembly of the magnetic ring 200. Specifically, the guide slope 31 is disposed towards the clamping space 1001, and the vertical dimension of the guide slope 31 gradually increases from its end to its root. The end of the guide slope 31 is the end of the guide slope 31 that is away from the fixing part 10 along the second horizontal direction, and the root of the guide slope 31 is the end of the guide slope 31 that is close to the fixing part 10 along the second horizontal direction.
[0054] When the magnetic ring 200 is assembled with the magnetic ring fixing device 100, it is only necessary to snap the magnetic ring 200 between the two clamping arms 20 and insert it into the clamping space 1001 under the guidance of the guide slope 31. The installation is simple and the operation is convenient.
[0055] like Figures 1-5 As shown, the clamping arm 20 includes a main body 21 and an extension 22. The main body 21 is connected to the fixing part 10. The extension 22 is formed by extending from one end of the main body 21 away from the fixing part 10 toward each other. The distance between the two extensions 22 is less than the size of the magnetic ring 200 in the first direction, so that the clamping arm 20 can hug the magnetic ring 200. Combined with the limiting part 30 provided in the vertical direction, the magnetic ring 200 is limited in the first horizontal direction, the second horizontal direction and the vertical direction, so as to prevent the magnetic ring 200 from coming out of the magnetic ring fixing device 100.
[0056] Optionally, a reinforcing structure 40 is provided on the fixing part 10. The reinforcing structure 40 is connected to the base plate and / or side plate of the fixing part 10 to improve the overall strength of the magnetic ring fixing device 100 and ensure the reliability of the magnetic ring fixing device 100 in limiting and fixing the magnetic ring 200.
[0057] Optionally, at least a portion of the reinforcing structure 40 is connected to the clamping arm 20 to improve the structural strength of the clamping arm 20 and prevent the clamping arm 20 from breaking during use.
[0058] Optionally, the limiting part 30, the clamping arm 20 and the fixing part 10 are integrally formed, which can reduce the connection structure between the components and reduce the number of parts; on the other hand, it can improve the overall strength of the magnetic ring fixing device 100.
[0059] Optionally, the magnetic ring fixing device 100 is formed by injection molding, which has high production efficiency and good product quality.
[0060] Optionally, the fixing part 10 is provided with a groove 13 that communicates with the clamping space 1001, which can increase the local rigidity of the fixing part 10 and increase the contact points between the magnetic ring 200 and the fixing part 10, thereby increasing stability.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
