[0033] As attached Figure 1-4As shown, in a schematic embodiment of an inductor pin fixing tool of the utility model, the inductor is arranged in a shell 1, and the pin 2 extends to the outside of the shell 1 through an opening on the upper surface of the shell 1. The fixing tool includes a positioning plate 3, a limit member 4 and a first connecting member 5.

[0034] Among them, the positioning plate 3 is parallel to the upper surface of the housing 1 and is spaced apart from the upper surface of the housing 1. A positioning groove 31 for accommodating the inductor pin 2 is provided on the end surface of the positioning plate 3 close to the upper surface of the housing 1. The end of the pin 2 extends into the positioning groove 31. Since the distance between the positioning plate 3 and the upper surface of the housing 1 is fixed, the vertical distance between the lower surface of the end of the pin 2 and the upper surface of the housing 1 is fixed after the pin 2 is fixed in the positioning groove 31. In this embodiment, the vertical distance between the lower surface of the end of the pin 2 and the upper surface of the housing 1 is fixed to 24.5 mm. This distance can be adjusted according to the design requirements of different inductor products by adjusting the spacing distance between the positioning plate 3 and the upper surface of the housing 1.

[0035] The limit member 4 is a strip-shaped plate structure, whose width is less than or equal to the width of the positioning plate 3, and is used to clamp and fix the inductor pin 2 in the positioning groove 31. The limit member 4 is fixedly connected to the positioning plate 3, and after the connection, the pin 2 is fixed between the positioning plate 3 and the limit member 4.

[0036] The first connecting member 5 is used to connect the positioning plate 3 and the housing 1 , one end of the first connecting member 5 is fixedly connected to the positioning plate 3 , and the other end of the first connecting member 5 is fixedly connected to the housing 1 .

[0037] The fixing fixture provided by the utility model ensures the accurate positioning of the inductor pin 2 outside the shell 1 through the coordinated use of the positioning plate 3 and the limit member 4, prevents the pin 2 from being skewed during production and installation, and realizes accurate control of the distance between the pin 2 and the shell 1 and the center distance between the pins 2, which not only solves the problem of fixing the inductor product and prevents the inductor product from shaking in the shell during production, but also ensures that multiple important dimensions of the inductor product meet predetermined requirements, greatly improves production efficiency and reduces labor costs.

[0038] In some embodiments of the utility model, a mounting hole is formed at the end of the pin 2; a boss 32 is provided in the positioning groove 31, and the cross-sectional shape of the boss 32 matches the shape of the mounting hole, both of which are elliptical, and the boss 32 is located in the mounting hole after the pin 2 is fixed. The size of the boss 32 is set according to the minimum size requirement of the mounting hole of the pin 2, and is used to check whether the size of the mounting hole on the pin 2 meets the minimum requirement.

[0039] In some embodiments of the present invention, the depth of the positioning groove 31 is equal to the thickness of the pin 2 to ensure that the end of the pin 2 can be fully embedded in the positioning groove 31, providing a better fixing effect and reducing the fluctuation of inductance performance caused by the instability of the pin 2.

[0040] In some embodiments of the present invention, the width of the positioning groove 31 is greater than or equal to the width of the pin 2, providing sufficient accommodation space for the pin 2. The width of the positioning groove 31 is set according to the maximum width requirement of the pin 2, and is used to check whether the width of the pin 2 meets the maximum requirement.

[0041] In some embodiments of the utility model, the pins 2 and the positioning grooves 31 each include two, the two positioning grooves 31 are arranged at intervals, and the distance between the two positioning grooves 31 is set according to the actual installation size requirements of the inductor product, and the two pins 2 extend into the two positioning grooves 31 respectively and are fixed.

[0042] In some embodiments of the utility model, the positioning plate 3 is provided with a first mounting hole 33 penetrating the plate surface thereof, the position of the stopper 4 corresponding to the first mounting hole 33 is provided with a threaded hole 41, and the positioning plate 3 and the stopper 4 are fixedly connected by bolts passing through the first mounting hole 33 and the threaded hole 41. The positioning plate 3 and the stopper 4 are fixedly connected by bolts, which provides a simple and effective connection method, facilitates quick installation and disassembly, and improves the convenience and maintainability of the fixing tool.

[0043] Furthermore, three first mounting holes 33 are provided to increase the number of fixing points. The three first mounting holes 33 are arranged at intervals, respectively arranged between the two positioning grooves 31 and on both sides of the two positioning grooves 31, to improve the stability of the connection between the positioning plate 3 and the limiting member 4.

[0044] In some embodiments of the utility model, the first connecting members 5 include two, the two first connecting members 5 are perpendicular to the positioning plate 3, and are fixedly connected to the two ends of the length direction of the positioning plate 3 by screws or bolts respectively. The end of the first connecting member 5 close to the shell 1 is connected to the upper surface of the shell 1 to ensure the balance of the positioning plate 3, provide better support for the positioning plate 3, and further enhance the overall stability of the fixing tooling, thereby improving the installation accuracy of the inductor.

[0045] In some embodiments of the utility model, a second connecting member 6 is further included, and the second connecting member 6 is used to connect the first connecting member 5 and the shell 1. The second connecting member 6 and the first connecting member 5 can be of an integral design or a split design. A second mounting hole 61 is opened on the second connecting member 6, and the second connecting member 6 is fixed to the upper surface of the shell 1 by a bolt passing through the second mounting hole 61 and a nut matching the bolt.

[0046] The method of using the fixing fixture provided in this embodiment is as follows: when using, first place the two pins 2 of the inductor on the two bosses 32 in the positioning groove 31 respectively, and then fix and lock the stopper 4 with the positioning plate 3 through three bolts. After locking, the pins 2 are fixed between the positioning plate 3 and the stopper 4. After locking the pins 2, place the fixing fixture as a whole on the upper surface of the housing 1, and fix it to the housing 1 through the second mounting hole 1 on the second connecting member 6 using bolts and nuts until it is locked without gaps. After the fixing fixture is fixedly connected to the housing 1, the vertical distance from the lower surface of the pin 2 to the upper surface of the housing is fixedly locked to 24.5 mm, so that the distance from the center of the pin 2 to the mounting hole of the housing 1 and the center distance between the two pins 2 can be guaranteed at the same time.

[0047] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
