Abstract: An improved structure of a chip socket is composed of a chip socket which is a square fixing seat, and a center of the fixing seat is provided with a cavity for holding a chip. Inner sides of the cavity are arranged with insertion slots for terminals, the cavity of fixing seat is provided with a fixing plate, and a side of the fixing plate is extended and arranged with insertion slots which are corresponding to pins of the terminals. Through the correspondence of insertion slots of the fixing plate to the terminals at insertion slots, the pins of terminals can be tidily arranged inside the insertion slots, such that the pins can be maintained at a horizontal direction and there will be no void solder phenomenon caused by welding the pins, when the chip socket is welded with a surface mounting technology.
