Its main functions include isolation and filtering of AC signals, and jointly forming a resonant circuit with other components (such as capacitors and resistors). However, due to the deficiencies in material properties and structural design of traditional magnetic core skeletons, there are often problems such as low strength of the corner structures and easy damage, which directly affect the overall performance and service life of the magnetic cores. Therefore, a magnetic core with a strengthened skeleton structure is needed;

A limiting component 6 is provided on one side of the top end of the second protection plate 4, and the position of the push plate 52 is fixed through the limiting component 6.

[0024] The clamping groove 32 is engaged with the clamping block 54 to fix the second protection plate 4. A positioning groove 41 for the sliding fit of the push plate 52 is formed on the surface of the second protection plate 4. The positioning groove 41 provides guidance for the movement of the push plate 52. Thread grooves 200 that match each other are formed at the bottom end of the protection block 42 and the other side of the top end of the first protection plate 2, and the two thread grooves 200 are connected by bolts to improve the firmness of the connection between the first protection plate 2 and the second protection plate 4.

[0025] A guiding rod 51 is slidably arranged inside the connecting seat 5. A first return spring 55 is sleeved on one side of the surface of the guiding rod 51. One end of the first return spring 55 is fixedly connected to the front end face of the connecting seat 5, and the other end of the first return spring 55 is fixedly connected to the rear end face of the push plate 52. One end of the guiding rod 51 is fixedly connected to the middle of the push plate 52, and the push plate 52 can be pulled to move synchronously through the guiding rod 51.

[0026] A connecting block 56 is provided at the other end of the guiding rod 51. A jack 57 is formed on the surface of the connecting block 56 for fixing the position of the connecting block 56.

[0027] Each limiting component 6 includes a fixing seat 61. The fixing seat 61 is arranged on one side of the top end of the corresponding second protection plate 4. A plug rod 62 is slidably arranged in the middle of the fixing seat 61. A pulling block 63 is provided at the top end of the plug rod 62. The plug rod 62 can be pulled to move upward through the pulling block 63. Second return springs 64 are provided on both sides of the bottom end of the pulling block 63. The second return springs 64 are in a contracted state in the natural state, and the bottom ends of the two second return springs 64 are fixedly connected to the upper surface of the fixing seat 61.

[0028] A connecting groove 611 that matches the connecting block 56 is formed on one side of the fixing seat 61. The inner wall of the connecting groove 611 is slidably matched with the surface of the connecting block 56. The bottom of the plug rod 62 is inserted into the inner wall of the jack 57.

[0029] On both sides of the first protective plate 2, there are first folding plates 21. On both sides of the second protective plate 4, there are second folding plates 43. The inner walls of the first folding plates 21 and the inner walls of the second folding plates 43 are attached to the surface of the framework magnetic core 1.

[0030] At the top end of the push plate 52, there is a connecting plate 58. The surface of the connecting plate 58 is provided with anti-slip grooves 59 to improve anti-slip performance. Through the connecting plate 58, it is convenient to push the push plate 52 to move.

[0031] During use, first, the first protective plate 2 is arranged below the corner of the framework magnetic core 1, and the second protective plate 4 is arranged above the corner of the framework magnetic core 1. The first protective plate 2 and the second protective plate 4 respectively protect the bottom end and the top end of the corner of the framework magnetic core 1. The protective box 3 at the top end of the first protective plate 2 protects the outer side of the corner of the framework magnetic core 1, and the protective block 42 at the bottom end of the second protective plate 4 protects the inner side of the corner of the framework magnetic core 1. The first folding plates 21 and the second folding plates 43 protect both sides of the corner of the framework magnetic core 1, thereby realizing the reinforcement of the structural strength of the framework magnetic core 1.

[0032] In order to facilitate the separate disassembly of the first protective plate 2 and the second protective plate 4, a push plate 52 is arranged above the second protective plate 4. The staff pushes the push plate 52 to move towards the fixed seat 61 through the connecting plate 58. When the push plate 52 moves, it drives the support plate 53 to move synchronously, so that the clamping block 54 disengages from the card slot 32 on the surface of the fixed block 31. When the push plate 52 moves, it drives the guide rod 51 and the connecting block 56 to move synchronously, and inserts the connecting block 56 into the connecting slot 611 on one side of the fixed seat 61. At this time, pull the pull block 63, and the pull block 63 drives the insertion rod 62 to move upward. When the jack 57 on the surface of the connecting block 56 moves below the insertion rod 62, release the pull block 63. Under the pulling force of the second return spring 64, the pull block 63 enables the insertion rod 62 to automatically insert into the jack 57, thereby fixing the position of the connecting block 56 and restricting the movement of the clamping block 54 at the same time. The staff does not need to keep pulling the push plate 52, liberating both hands. At this time, the bolts between the threaded grooves 200 can be unscrewed to complete the disassembly of the first protective plate 2 and the second protective plate 4, making daily maintenance more convenient and the disassembly process more convenient.

[0033] At this time, the first return spring 55 is in a contracted state. When installing the second protective plate 4, after placing the second protective plate 4 in position, the pull block 63 can be pulled upward to make the insertion rod 62 disengage from the jack 57. Under the elastic force of the first return spring 55, the push plate 52 moves away from the limiting component 6, so that the clamping block 54 automatically snaps into the card slot 32, making the installation process more convenient.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
