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，它坚实的外壳保护着板卡、电源及存储设备，能防压、防冲击、防尘，并且它还能发挥防电磁干扰、辐射的功能，起屏蔽电磁辐射的作用。

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.

机箱配件接地弹片装置于印刷电路板与金属壳体间,其中主要具有一弹压部,该弹压部的二端分别延伸,形成有一可与印刷电路板相组固的固定面,及一与壳体相接触的抵接面,当其组配完成时,印刷电路板会将弹片略为向壳体压掣,并藉由该弹压部的弹性力,促使抵接面与壳体构成接触的部分更加密合,以增加其导电性,达到降低电磁辐射的目的。

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.

机箱配件PCB连接座是一类应用非常广泛的连接器,也是一个非常广义的类别,它将印制电路板或子卡连接到一个背板或母板上,或通过电线与电缆将印制电路板连接到外部系统.包括条状引线头,FPC/FFC,边缘连接器,高密度的MIL-C-55302连接器。

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.
