Jinan chassis and cabinet suppliers share the purpose of chassis and cabinet: provide space for storage devices such as mainboard, power supply, various expansion boards, optical drives, floppy drives and hard drives, and firmly fix these parts inside the chassis through supports, brackets, screws or clips and other connectors inside the chassis to form an intensive whole.

其次，它堅實的外殼保護著板卡、電源及存儲設備，能防壓、防沖擊、防塵，并且它還能發揮防電磁干擾、輻射的功能，起屏蔽電磁輻射的作用。

Secondly, its solid shell protects the board, power supply and storage equipment, can prevent pressure, impact and dust, and it can also play the function of anti electromagnetic interference and radiation, and play the role of shielding electromagnetic radiation.

機箱配件接地彈片裝置于印刷電路板與金屬殼體間,其中主要具有一彈壓部,該彈壓部的二端分別延伸,形成有一可與印刷電路板相組固的固定面,及一與殼體相接觸的抵接面,當其組配完成時,印刷電路板會將彈片略為向殼體壓掣,并藉由該彈壓部的彈性力,促使抵接面與殼體構成接觸的部分更加密合,以增加其導電性,達到降低電磁輻射的目的。

The chassis accessory grounding spring piece is installed between the printed circuit board and the metal shell, which is mainly provided with an elastic pressing part. The two ends of the elastic pressing part extend respectively to form a fixed surface that can be assembled with the printed circuit board and a butting surface in contact with the shell. When the assembly is completed, the printed circuit board will slightly press the spring piece against the shell, and through the elastic force of the elastic pressing part, Make the contact part between the butting surface and the shell more closely, so as to increase its conductivity and reduce electromagnetic radiation.

機箱配件PCB連接座是一類應用非常廣泛的連接器,也是一個非常廣義的類別,它將印制電路板或子卡連接到一個背板或母板上,或通過電線與電纜將印制電路板連接到外部系統.包括條狀引線頭,FPC/FFC,邊緣連接器,高密度的MIL-C-55302連接器。

Chassis accessories PCB connector base is a kind of widely used connector, which is also a very broad category. It connects the printed circuit board or sub card to a backplane or motherboard, or connects the printed circuit board to the external system through wires and cables Including strip lead head, FPC / FFC, edge connector and high-density mil-c-55302 connector.
