Electrical connector forming extreme dimension

Abstract

The invention provides an electrical connector forming an extreme dimension. The electrical connector comprises a main body and mobile devices fixed on the two ends of the main body, wherein each of the two ends of the main body has a tower-shaped portion formed by a pair of upper portions and a pair of lower portions adjacent to the upper portions. The structure is reliable and stable, and the mobile devices are replaceable.

Problems solved by technology

[0003] Although the traditional computer circuit board clamping equipment can easily push out the card-carrying circuit board, and can effectively protect the electronic components around the electrical connection device forming a limit size, however, this traditional computer circuit board clamping device has some disadvantages

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 electrical connection device that forms the limit size, it is necessary to forcibly squeeze the movable device with the help of a tool. When damaged, the movable device cannot be replaced separately, but the electrical connection device which forms a limit size as a whole must be replaced, so it is inconvenient to use; in addition, there is a gap between the rear ends of the two side walls of this traditional computer circuit board clamping device, making The strength of this part is reduced, 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 to be shaken and unstable, which will affect the reliability of its connection with other circuits
