Combined simple computer circuit board clamping device

Abstract

The present invention is a combined simple computer circuit board clamping device, which includes a main body and movable devices fixed at both ends of the main body. The two ends of the main body have tower-shaped parts formed by a pair of upper parts and a pair of lower parts adjacent to the pair of upper parts. , the present invention is a combined simple computer circuit board clamping device with stable and reliable structure and replaceable movable device.

[0003] Although the traditional computer circuit board clamping device can easily eject the card-carrying circuit board, and can effectively protect the electronic components around the combined simple computer circuit board clamping device, yet this traditional computer circuit board clamping device has some shortcoming

First of all, because the fixed end face actually mainly limits the ejection part, but cannot limit the insertion part, and the distance between the rotation center axis and the ejection part is much smaller than the distance between the rotation center axis and the insertion part , in fact, a longer moment arm is formed between the insertion part and the rotation center axis. When the insertion part is rotated, the applied external force acts together with the longer moment arm to generate a larger rotational moment. The force is too strong and the movable device is broken, so that the card-carried circuit board cannot be taken out; secondly, because the installation structure of the rotating central axis of the computer circuit board clamping equipment is a closed structure, and the movable device is generally made of hard materials, so When installing the movable device to the combined simple computer circuit board clamping device, the movable device must be forcibly squeezed with the help of a tool. Once installed, the movable device is difficult to detach from the combined simple computer circuit board clamping device again. And then when the movable device is damaged, the movable device cannot be replaced separately, but the integrated simple computer circuit board clamping device must be replaced, so it is inconvenient to use; in addition, the rear ends of the two side walls of this traditional computer circuit board clamping device There is a gap between them, which reduces the strength of this part, so that the movable device cannot be stably installed in this position, and it will also cause the card-on-board circuit board to be installed unstable, which will affect the reliability of its connection with other circuits
