Electrical connector structure

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an electrical connector structure, and more particularly to an electrical connector structure that is configured to be driven by a drive wheel drive portion to rotate a drive portion to urge the cover to slide.

Current processors on the market have a large array of pins that provide an electrical path between the pins and the recesses on the board through the socket, and the zero insertion force socket applies a cover that slides between the switch positions on the base. This sliding movement can be driven by a drive member such as a hand tool that rotates (e.g., a flat-blade). The array holes of the cover correspond to the pins of the processor.

When the processor is fixed, the stitches are firstly engaged with the socket through the array hole. When the cover is in the open position, the pins penetrate the hole of the cover and penetrate into the pin receiving hole of the base, but are not connected with the pins. The conductive terminals in the receiving holes are electrically connected; if the cover is moved to the closed position, the pins are moved to be electrically connected to the conductive terminals in the pin receiving holes.

Since the processor may have hundreds of pins, moving the cover to the closed position requires considerable force to move the pins to a fully mated position that can cause the socket combination to bend, resulting in insufficient drive or disabling the drive.

The conventional driving member is usually a rotatable eccentric wheel, and the rotation of the eccentric wheel can drive the cover body to slide relative to the base, and the eccentric wheel includes a stepped cylinder integrally formed from top to bottom and connected to each other when used. When the driving member is rotated by the hand tool, the stepped cylinder is eccentrically rotated to drive the cover body to move on the base.

Although the above structure can achieve the effect of displacing the cover body on the base, the stepped cylinder of the eccentric is not easy to manufacture, which may cause an increase in manufacturing cost.

It can be seen that there are still many shortcomings in the above-mentioned conventional structure, which is not a good designer, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional structure, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in research and development of the electrical connector structure.
