Description

A kind of hard disk shell

Technical field

The utility model belongs to storage equipment technical field, specifically, being related to a kind of hard disk shell.

Background technique

With the continuous progress of science and technology, the requirement in current big data era, to the access speed of hard disk, capacity, volume Also in the continuous improvement, solid state hard disk (Solid State Disk, abbreviation SSD) is used as a kind of good memory, is opened with it It moves the plurality of advantages such as fast, read or write speed is fast, small in size, noiseless, calorific value is low and is widely used, outside existing solid state hard disk It is all to be fixed together upper and lower covers with the mode for playing screw when shell upper cover and lower cover combine, it is hard in production and assembly solid-state When disk, due to there is the process for playing screw, built-up time is increased, production efficiency is lower, while upper and lower covers need more screw threads Hole and stud, upper and lower covers design is complicated, and the process for producing shell is more, and efficiency is also low；In addition, electrostatic can be to the service life of hard disk It has a huge impact.Hard disk can usually generate a large amount of electrostatic in the process of running, be accumulated in metal hard disk shell On, after the charge of accumulation of static electricity reaches certain degree, the case where just will appear electrostatic shelf depreciation, the electric current that moment generates It is likely to result in inside the generation of bad track of hard disk, or injury hard disk than more sensitive control chip.It can thus be stated that electrostatic is The invisible killer of hard disk.

Mobile hard disk generally comprises the shell of mobile hard disk and is arranged in the intracorporal hard disk of shell.Movement in the prior art is hard The electrostatic protection measure of disk typically passes through the device of some such as shielding cases or screw, and the surface of hard disk and movement is hard The enclosure interior of disk is connected, and the electrostatic that harddisk surface generates is exported to the surface of shell of mobile hard disk, passes through connecing for user Touching or other electric conductors being in contact with mobile hard disk, the electrostatic for indirectly generating hard disk export.

Such design is so that the electrostatic that hard disk generates can be distributed to the surface of the shell of mobile hard disk, if can mobile hard disk It is placed on insulator and for a long time in use, the electrostatic that mobile hard disk generates may can not find the approach of release, and The shell and harddisk surface of mobile hard disk largely gather, and when gathering to a certain extent, just will appear the feelings of electrostatic shelf depreciation Condition causes to damage hard disk, still it cannot be guaranteed that the safe handling of mobile hard disk.

Therefore, it is necessary to improve to shortcomings and deficiencies of the prior art, a kind of hard disk shell is provided, it is above-mentioned to solve Solid state hard disk upper cover, which is easy to be crushed out of shape, produces the problem of expending material, process increase with shell, while can be by the heat in hard disk Outside conduction is measured, and Electro-static Driven Comb can be fallen, electrostatic is avoided to damage the electronic component in mobile hard disk, to mention The safety of data in high mobile hard disk.
