Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core storage devices, in particular to a magnetic core protection box. Background Art

[0002] The core protection box is mainly used to protect the magnetic core placed inside. It can effectively protect the magnetic core from the influence of the external environment and ensure the performance and stability of the magnetic core.

[0003] like Figure 1 The structure of the ET core 100 shown has an "8"-shaped cross-section. In the existing core protection box, two pillars are generally constructed in the box body of the core protection box to match the hole on the ET core 100 when the ET core 100 is stored in the corresponding core protection box. In the existing design, the specifications of the pillars are fixed to accommodate the placement of ET cores 100 of different specifications. In order to completely place the ET core 100 in the box body, after placement, there will be a certain gap margin between the inner wall of the hole of the ET core 100 and the pillar. This margin will cause the ET core 100 to wear due to friction between the ET core 100 and the box body during transportation of the core protection box containing the ET core 100, thereby affecting the quality of the ET core 100.

[0004] In addition, regarding the above problem, if the pillars in the core protection box are designed to match the specifications of the holes so as to make the core protection box a dedicated product for the ET core, this will increase the cost of using the core protection box.

[0033] As a preferred embodiment of the present invention, Figure 2 As shown, a magnetic core protection box for storing ET magnetic cores, comprising:

[0034] The box body 1 is provided with two first limiting ring columns 11, and the inner ring position of the first limiting ring columns 11 is formed with a first inner ring wall 111 extending upward, and a first abutting step 112 is formed on the first limiting ring columns 11 near the first inner ring wall 111;

[0035] A box cover 2 detachably connected to the box body 1 is provided with two second limiting ring columns 21 for use with the first limiting ring columns 11. The second limiting ring columns 21 match the shape of the hole in the ET core. A first outer ring wall 211 extending downward is formed at the outer ring position of the second limiting ring columns 21. A second abutment step 212 is formed on the second limiting ring columns 21 adjacent to the first inner ring wall 111.

[0036] After the box body 1 and the box cover 2 are assembled, the two first limiting ring columns 11 are respectively placed in the two holes in the ET magnetic core, and the two first limiting ring columns 11 are aligned and spliced ​​with the two second limiting ring columns 21 one by one. The first abutting step 12 abuts against the lower end of the first outer ring wall 211, and the second abutting step 212 abuts against the upper end of the first inner ring wall 111. The first inner ring wall 111 and the corresponding first outer ring wall 211, and the first outer ring wall 211 are tightly against the ET magnetic core.

[0037] A magnetic core protective box in this embodiment is used to store ET magnetic cores. It includes a box body 1 and a box cover 2 detachably connected to the box body 1. By respectively providing two first limiting ring columns 11 and second limiting ring columns 21 on the box body 1 and the box cover 2, the first limiting ring columns 11 and the second limiting ring columns 21 can be aligned and spliced one by one. And the first limiting ring columns 11 are configured to have a first outer ring wall 211 extending upward凸出 and a first abutting step 112, and the second limiting ring columns 21 are configured to have a second inner ring wall 101 extending downward凸出 and a second abutting step 212. After the box body 1 and the box cover 2 are assembled, the first abutting step 112 abuts against the corresponding second abutting step 212, and the first inner ring wall 111 is closely attached to the corresponding first outer ring wall 211, thus completing the assembly between the box body 1 and the box cover 2. In this, the ET magnetic core is stably positioned during storage by using the first outer ring wall 211 to tightly abut against the ET magnetic core. In addition, the width of the first outer ring wall 211 can be set to adapt to the specifications of different ET magnetic cores, saving manufacturing costs for application.

[0038] It should be noted that the first limiting ring columns 11 provided in the box body 1 and the shape of the box body 1 itself are used to initially position the ET magnetic cores to be stored. Since the second limiting ring columns 21 match the shape of the holes in the ET magnetic cores, and then the ET magnetic cores are further stabilized by using the second limiting ring columns 21 in the box cover 2. In application, only the box cover 2 and the second limiting ring columns 21 in the box cover 2 need to match the specifications of the ET magnetic cores, and thus the design cost can be reduced.

[0039] For example, when the specification of the first limiting ring columns 11 is smaller than that of the second limiting ring columns 21, the magnetic core protective box can store ET magnetic cores with a hole diameter larger than the first limiting ring columns 11, and the second limiting ring columns 21 are used to abut against the ET magnetic cores for stable positioning.

[0040] When the specification of the first limiting ring columns 11 is equal to that of the second limiting ring columns 21, the magnetic core protective box can store ET magnetic cores with the same hole diameter as the first limiting ring columns 11. The hole size of this ET magnetic core is the same as the specification of the first limiting ring columns. At this time, the ET magnetic cores can be stably positioned by using the first limiting ring columns 11 or can be stably positioned in cooperation with the first limiting ring columns 11.

[0041] When the specification of the first limiting ring columns 11 is larger than that of the second limiting ring columns 21, the magnetic core protective box can store special-shaped ET magnetic cores, such as ET magnetic cores with a partial shape of "丅". After the ET magnetic cores with this shape are put into the box body, the ET magnetic cores with a partial shape of "丅" will partially cover the first abutting step. At this time, the second limiting ring columns 21 are used to abut against the ET magnetic cores for stable positioning.

[0042] Combined with the above, the box cover

[0043] Regarding the arrangement positions of the first limiting ring column 11 and the second limiting ring column 21 in this embodiment, as shown in FIG. Figure 2 As shown, the two first limiting ring columns 11 are arranged at a distance from each other in the middle of the box body 1;

[0044] The two second limiting ring columns 21 are arranged at a distance from each other in the middle of the box cover 2 .

[0045] The above is used to match the shape of the "8" ET core.

[0046] In addition, the two first limiting ring columns 11 are integrally formed on the box body 1, which can improve the structural stability of the first limiting ring columns 11;

[0047] Likewise, the two second limiting ring columns 21 are integrally formed on the box cover 2 , which can improve the structural stability of the second limiting ring columns 21 .

[0048] For example, in this embodiment, the box body 1 and the box cover 2 are both straight cylindrical structures, and the design space in the box body 1 and the box cover 2 is narrow. If the first limiting ring column 11 and the second limiting ring column 21 are both arranged in an assembled manner, the first limiting ring column 11 and the second limiting ring column 21 are easy to fall off. Therefore, an integrated molding structure is adopted, and during application and production, the box body 1 with the first limiting ring column 11 and the box cover 2 with the second limiting ring column 21 are convenient for injection molding.

[0049] In this embodiment, if Figure 2 As shown, a vertically penetrating first cavity 113 is formed in the two first limiting ring columns 11;

[0050] A vertically penetrating second cavity 213 is formed in the two second limiting ring columns 21;

[0051] After the box body 1 and the box cover 2 are assembled, the two first limiting ring columns 11 and the two second limiting ring columns 21 are aligned and spliced ​​one by one, and the first cavities 113 and the second cavities 213 in the two first limiting ring columns 11 and the two second limiting ring columns 21 are aligned and connected one by one. Long rods can be set in the first cavity 113 and the second cavity 213 to facilitate the positioning of the magnetic core protective box during transportation.

[0052] In this embodiment, the detachable connection between the box body 1 and the box cover 2 is as follows: Figure 2 As shown, a second inner ring wall 101 is formed along the upper end of the box body 1;

[0053] A second outer ring wall 201 is formed along the lower end of the box cover 2;

[0054] The box body 1 and the box cover 2 are assembled by the second inner ring wall 101 and the second outer ring abutting against each other.

[0055] In addition, a plurality of buckles 1011 protruding outward are provided on the outer periphery of the second inner ring wall 101. In this embodiment, the box body 1 is a square straight cylindrical structure, and preferably four buckles 1011 are provided.

[0056] The inner circumference of the second outer ring wall 201 is provided with a plurality of inwardly recessed slots 2011. Similarly, in this embodiment, the box cover 2 is a square straight cylindrical structure, and preferably four such slots 2011 are provided to match with the buckle 1011.

[0057] After the box body 1 and the box cover 2 are assembled, the four buckles 1011 correspond to the four slots 2011 one by one, and each buckle 1011 is correspondingly embedded in the slot 2011 .

[0058] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
