The three edge difference mode magnetic columns and the center common mode magnetic column are arranged between the first magnetic yoke and the second magnetic yoke and parallel to each other. Each edge difference mode magnetic column is provided with a first winding, and the center common mode magnetic column is provided with three second windings. The currents of the three second windings correspond to the currents of one phase of three-phase current and have the same direction, and the winding direction of the first windings on the three edge difference mode magnetic columns is also the same as the direction of the current of one phase of three-phase current.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: a three-phase differential and common-mode integrated inductor with independently assembleable terminals, including a differential-mode magnetic core 2 sleeved on the outer wall of the common-mode magnetic core 1, a flat wire winding 3 wound on the common-mode magnetic core 1 on both sides of the differential-mode magnetic core 2, a base 4 connected to the connector end of the flat wire winding 3, and a sleeve 5 connected to the other side of the base 4.

[0024] The sleeve 5 has a terminal 6 inserted inside. The outer wall of the center end of the terminal 6 has an annular notch 61. The outer wall of the annular notch 61 near the bottom has a threaded groove. The outer wall of the annular notch 61 at the upper end of the threaded groove has a smooth surface structure.

[0025] Preferably, the top of the sleeve 5 is fixedly connected to an end sleeve 51, and two retaining strips 52 are symmetrically installed on the inner wall of the sleeve 5.

[0026] Preferably, a fixed sleeve 63 is movably sleeved on the smooth outer wall of the annular notch 61, and a toggle post 64 is fixedly installed on the surface of the fixed sleeve 63;

[0027] In use, the fixed sleeve 63 is rotated by turning the pin 64, so that the fixed sleeve 63 can be fully engaged with the inside of the end sleeve 51.

[0028] Two slots 62 are symmetrically provided at the bottom of the terminal block 6. When the terminal block 6 is connected to the sleeve 5, each slot 62 is engaged with a locking strip 52.

[0029] In practical use, the fixed sleeve 63 can be moved to the upper end of the toggle post 64 before docking, so as not to interfere with the docking between the terminal post 6 and the sleeve 5.

[0030] Preferably, the inner wall of the end sleeve 51 is provided with a threaded groove, and the inner and outer walls of the fixing sleeve 63 are provided with threaded structures.

[0031] The threaded structure on the inner wall of the fixed sleeve 63 matches the threaded structure on the annular notch 61, and the threaded structure on the outer wall of the fixed sleeve 63 matches the threaded structure on the inner wall of the end sleeve 51.

[0032] In practical use, the terminal block 6 and sleeve 5 in this technical solution are assembled using a movable connection method. The detailed operating steps are as follows, which aims to ensure the convenience and stability of installation:

[0033] During installation, first insert the terminal 6 into the internal space of the sleeve 5. During this process, special attention must be paid to precisely aligning the slots 62 on both sides of the terminal 6 with the two retaining strips 52 inside the sleeve 5. Continue until the bottom of the terminal 6 is fully embedded deep into the sleeve 5.

[0034] Subsequently, the fixing sleeve 63 needs to be slowly moved along the terminal post 6 to the port position of the end sleeve 51 and rotated. As the fixing sleeve 63 rotates, it gradually and tightly pushes into the interior of the end sleeve 51 through the threaded structure between the annular notch 61 and the end sleeve 51.

[0035] When the retaining sleeve 63 is fully screwed in and tightly fitted inside the end sleeve 51, a firm and stable connection is formed between the terminal 6 and the end sleeve 51. At this point, the connection between the terminal 6 and the sleeve 5 is complete.

[0036] Through this series of operations and designs, this technical solution not only achieves quick and easy connection between terminal 6 and sleeve 5, but also provides stable support and protection in terms of structure, laying a solid foundation for subsequent electrical connections and the operation of the overall product.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
