In computer casing, the general magnet stand that data access is installed is by the conductive metallic material manufacturing, static in the data access can be derived through magnet stand and housing, if make but the magnet stand that data access is installed is an insulating material such as rubber, the static that accumulates in the data access can't discharge, the instantaneous large-current that static discharge produces may burn out device to the joule heating effect that electronic product produces, and the electromagnetic field of static discharge radiation can produce interference to electronic product on the other hand.
Therefore,, how to provide a kind of device that prevents that data access lost efficacy because of static discharge, be the problem that this case institute desire solves when magnet stand is an insulating material such as rubber when making.
[summary of the invention]
The purpose of this utility model is to provide a kind of and static in the data access can be derived via casing, and prevents the computer casing that the assembly in the data access lost efficacy because of static discharge.
The purpose of this utility model is achieved through the following technical solutions: the utility model computer casing comprises a computer header board, a magnet stand, and an electrostatic protection apparatus.This magnet stand is provided with a depression.This electrostatic protection apparatus system forms with the conductive material bending, can be installed between data access and the computer header board, it comprises a body and a butt body, this body can be placed in this depression, and itself and this data access connects, and this butt body is outwards bent to extend by this body and forms, itself and computer header board connect, electrically connect thereby this data access and computer chassis are formed,, the static discharge on the data access is derived via computer chassis to reach the ground connection effect.
The utility model computer casing is derived the static in the data access by an electrostatic protection apparatus, thereby can prevent the generation of the interior assembly of data access unit because of the static discharge Problem of Failure.
