Problems solved by technology

Because the contact between the hole wall of the through hole of the I / O block and the connector is not tight, it may cause electromagnetic leakage, which will cause interference to the surrounding electronic equipment and even cause harm to the human body.

Embodiment Construction

[0010] Please refer to Figures 1 to 3 , the computer case of the present invention includes a backplane 10 and an I / O block 20 disposed on the backplane 10 . The I / O block 20 is provided with a plurality of through holes 201 for the connectors 300 in the computer case to pass through, such as monitor connectors, printer connectors, mouse connectors and the like. The I / O block 20 extends obliquely from the edge of each through hole 201 toward the inside of the chassis and toward the center of the through hole 201 to form a plurality of elastic pieces 203 . Each elastic piece 203 is wave-shaped along its extending direction.

[0011] Please continue to refer image 3 , when installing the connector 300, align the through holes 201 corresponding to the I / O block 20, and pull the elastic pieces 203 into the chassis to deform them, so that the connector 300 can pass through the I / O block from the inside to the outside. The through hole 201 corresponding to the / O blocking plate...

Abstract

The invention discloses a computer case, which comprises a back plate and an input / output (I / O) separation blade which is fixed on the back plate, wherein the separation blade is provided with a plurality of through holes for accommodating connectors which correspond to a main board arranged in the computer case; and a plurality of elastic sheets extend from the edges of the through holes on the separation blade towards the inside of the case. Compared with the prior art, the I / O separation blade of the computer case is provided with the elastic sheets, so that the back plate of the case is tightly contacted with the connectors and good electromagnetic shielding effect is achieved.

Description

technical field [0001] The invention relates to a computer case. Background technique [0002] An I / O (input / output) block is usually provided on the backboard of the existing computer case. The I / O block is provided with a number of through holes, so that the connectors installed on the main board in the case are exposed from the case to connect with other electronic devices, such as monitors and printers. Since the hole wall of the through hole of the I / O block is not in close contact with the connector, electromagnetic leakage may be caused, thereby causing interference to surrounding electronic equipment, and even causing harm to the human body. Contents of the invention [0003] In view of the above, it is necessary to provide a computer case that can effectively prevent electromagnetic radiation. [0004] A computer case, comprising a backboard and an I / O block fixed on the backboard, the I / O block is provided with a plurality of through holes for accommodating con...
