[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figs. 1-3 This utility model provides a technical solution:

[0024] An inductor magnetic powder core includes a first magnetic ring 1 and a second magnetic ring 2. The first magnetic ring 1 is located outside the second magnetic ring 2, and connecting components 3 are provided on both sides of the first magnetic ring 1 near the end of the second magnetic ring 2.

[0025] The first magnetic ring 1 is assembled with the second magnetic ring 2 through the connecting component 3. The connecting component 3 consists of a connecting block 4, a moving block 5, two sets of first limiting blocks 6 and a connecting plate 7. The connecting block 4 is fixedly connected to the end of the first magnetic ring 1 near the second magnetic ring 2. The moving block 5 is slidably connected to the end of the connecting block 4 away from the first magnetic ring 1. The two sets of first limiting blocks 6 are slidably connected to both sides of the moving block 5. The connecting plate 7 is located at the top of the first magnetic ring 1 and the second magnetic ring 2.

[0026] Furthermore, a first sliding groove 8 is provided inside the connecting block 4 and outside the moving block 5. The connecting block 4 and the first sliding groove 8 are slidably connected. A first compression spring 9 is fixedly connected to the connecting block 4 extending into the interior of the first sliding groove 8, which slidably connects the moving block 5 to the first sliding groove 8. When the moving block 5 moves, it can be guided by the first sliding groove 8 to prevent deviation. The first compression spring 9, in conjunction with the first sliding groove 8, can drive the moving block 5 to move.

[0027] The movable block 5 has a second sliding groove 10 inside and outside the first limiting block 6. The first limiting block 6 and the second sliding groove 10 are slidably connected. The first limiting block 6 extends into the interior of the second sliding groove 10 and is fixedly connected to a second compression spring 11. The first limiting block 6 and the second sliding groove 10 are slidably connected. When the first limiting block 6 is displaced, the second sliding groove 10 can guide it to prevent deviation. The second compression spring 11, in conjunction with the second sliding groove 10, can drive the first limiting block 6 to move.

[0028] Secondly, the second magnetic ring 2 has receiving grooves 12 at both ends near the first magnetic ring 1. The two sides inside the receiving groove 12 are slidably connected to the second limiting blocks 13. The second limiting blocks 13 extend into the receiving groove 12 and are fixedly connected to the third compression springs 14. The first magnetic ring 1 and the second magnetic ring 2 are connected, so that the connecting block 4 is displaced into the receiving groove 12. The first compression spring 9 drives the moving block 5 to move to the bottom of the receiving groove 12 and fits the moving block 5 into the receiving groove 12. This makes the first limiting block 6 contact the second limiting block 13. The second compression spring 11 drives the first limiting block 6 to move, so that the first limiting block 6 presses the second limiting block 13. The third compression spring 14 drives the second limiting block 13 to move, so that the second limiting block 13 presses the first limiting block 6, thereby limiting the first limiting block 6 into the receiving groove 12.

[0029] Furthermore, the top of the first magnetic ring 1 and the second magnetic ring 2, located on the outside of the connecting plate 7, are both provided with connecting grooves 15. Limiting grooves 16 are provided inside the connecting grooves 15, the receiving groove 12, and the moving block 5. Limiting rods 17 are fixedly connected to both ends of the bottom of the connecting plate 7. The end of the limiting rod 17 away from the connecting plate 7 extends into the interior of multiple sets of limiting grooves 16. When the moving block 5 moves into the interior of the receiving groove 12, the connecting plate 7 is moved into the interior of the connecting groove 15, so that the limiting rod 17 moves into the interior of multiple sets of limiting grooves 16 and makes a limiting connection with the first magnetic ring 1, the second magnetic ring 2, the moving block 5, and the receiving groove 12, thereby increasing the stability of the assembly of the first magnetic ring 1 and the second magnetic ring 2.

[0030] Furthermore, both the first limiting block 6 and the second limiting block 13 are trapezoidal in design, and the edges of both the first limiting block 6 and the second limiting block 13 are arc-shaped. The trapezoidal design of the first limiting block 6 and the second limiting block 13, combined with the arc-shaped design of the edges, allows the first limiting block 6 to easily move to the outside of the second limiting block 13, thereby moving the second limiting block 13. At the same time, it can also easily move out from the outside of the second limiting block 13 and out from the inside of the receiving groove 12.

[0031] In this embodiment, the specific implementation scenario is as follows: In actual use, the first magnetic ring 1 and the second magnetic ring 2 are connected, causing the connecting block 4 to move into the interior of the receiving groove 12. The first compression spring 9 drives the moving block 5 to move to the bottom of the receiving groove 12, bringing the moving block 5 into contact with the interior of the receiving groove 12. The second compression spring 11 drives the first limiting block 6 to move, causing the first limiting block 6 to press against the second limiting block 13. The third compression spring 14 then drives the second limiting block... The second limiting block 13 is displaced, causing the second limiting block 13 to press the first limiting block 6, thereby limiting the first limiting block 6 inside the receiving groove 12. When the moving block 5 is displaced to the inside of the receiving groove 12, the connecting plate 7 is displaced to the inside of the connecting groove 15, causing the limiting rod 17 to be displaced to the inside of multiple sets of limiting grooves 16, and making a limiting connection with the first magnetic ring 1, the second magnetic ring 2, the moving block 5 and the receiving groove 12, thereby increasing the stability of the assembly of the first magnetic ring 1 and the second magnetic ring 2. Compared with the existing inductor magnetic powder core, this utility model can improve the overall practicality of the inductor magnetic powder core through design.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
