Description

Technical Field

[0001] The utility model relates to the field of mobile hard disk devices, and particularly relates to an electromagnetic shielding cover for a mobile hard disk. Background Technique

[0002] The electromagnetic shielding technology of mobile hard disks is an important means to ensure their normal operation and data security. In modern electronic devices, electromagnetic interference is a common problem. Especially in a high-density and high-frequency electronic environment, as a portable storage device, a mobile hard disk usually contains a mechanical hard disk or a solid-state drive, as well as corresponding adapter circuit boards and other components. These components are prone to external electromagnetic interference during operation. Therefore, an electromagnetic shielding cover needs to be adopted outside it for electromagnetic shielding;

[0003] According to the technical means described in the electromagnetic shielding cover for a mobile hard disk with the application number 202323075177.1, in this utility model, the electromagnetic shielding cover and the insertion block are embedded into the inside of the secondary body shell and the main body shell from the secondary body shell, so that the electromagnetic shielding cover is fixedly arranged in parallel inside the shell. Two groups of electromagnetic shielding covers are respectively installed at the upper and lower ends of the insertion block, so that the two rectangular electromagnetic shielding covers can form a clamping plate structure and wrap around the outer ends of the mobile hard disk components. While normally carrying out electromagnetic shielding protection, compared with the traditional "concave" shell structure, it does not need to be fixed by bolts, and can be quickly inserted, removed, and disassembled, making it more convenient to clean the dust;

[0004] However, after long-term use, after the shielding cover and the shell are inserted and removed multiple times, the groove wall of the fixing groove opened on the side of the shell for the shielding cover to be inserted and removed has a reduced surface friction coefficient and a reduced friction force on the shielding cover after long-term friction, resulting in the shielding cover being prone to loosening and falling off in the fixing groove. To solve this problem, a new type of electromagnetic shielding cover for a mobile hard disk is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electromagnetic shielding cover for a mobile hard disk to solve the problems put forward in the above background technique.

[0015] The technical effects and advantages of the present utility model:

[0028] It should be noted that the sleeve 401 is fixedly bonded to the hard disk housing 1 with glue. The control rod 402 and the spherical protrusion 403 are both made of stainless steel and are integrally cast. Limiting grooves 201 for the spherical protrusion 403 to penetrate are symmetrically formed on the side of the connecting block 2. The arrangement of the spherical protrusion 403 and the hemispherical limiting groove 201 facilitates the penetration and detachment between them.
