Electrical socket having improved cam

摘要

An electrical socket used for an electronic package with a plurality of pins, includes a base defining a number of passageways in a vertical direction. A number of contacts are received in the passageways. A cover is slidably mounted upon the base and defines a plurality of holes corresponding to the passageways. A cam is used for driving the cover horizontally moved along the base between an open position and a closed position. Wherein, the pins moves with regard to the contact in a linear return path when the electrical socket moved from the open position to the closed position or from the closed position to the open position.
