The base is provided with a plurality of terminal receiving slots, and a plurality of conductive terminals are correspondingly inserted into the terminal receiving slots, and the cover corresponding to the terminal receiving slots is provided with a plurality of through holes. When the cover is in the open position, the pins of the chip module are inserted into the corresponding terminal receiving slots through the through holes of the cover. At this time, the pins of the chip module are not in contact with the conductive terminals, and the wafer module can be inserted with zero force. Assembling to the socket connector; when the cover is switched from the open position to the closed position, the pins of the chip module are electrically touched with the corresponding conductive terminals in the terminal receiving groove, thereby realizing the electrical connection between the chip module and the printed circuit board. Turn on. Wherein, the driving device drives the cover to open or close by rotating the cam mechanism with the base as a base point. In order to ensure the strength of the base point of the base, a piece of substrate is often disposed on the base, and the block substrate is provided with a punching hole formed by punching, and the cam mechanism rotates around the punching hole, the cam When the mechanism rotates, it rubs against the inner wall of the punching hole. Since the inner wall of the punching hole is formed by punching and punching the hole, the flatness cannot be ensured, and the secondary processing is not considered in consideration of cost and technical problems. Plastic cam mechanism and this kind When the punching hole is matched, it is easy to wear. After the wear, the cam mechanism forms a gap between the punching holes, and the generated gap shortens the driving process of the cover plate, thereby causing poor contact between the pins of the wafer module and the conductive terminals.

The strip-shaped resisting strips 61 are disposed in the slots 205 below the mounting holes 204, and the second abutting portions 620 of the curved resisting strips 62 are disposed in the slots 205 above the mounting holes 204, and the retaining portions 621 are disposed on the strips 205. The slots 205 are mounted on both sides of the aperture 204. The first abutting portion 610 and the second abutting portion 620 communicate with the mounting hole 204 through the notch 206 . The retaining portion 621 of the curved abutting strip 62 is a bent hook formed downward from the two ends of the second abutting portion 620 , and the strip-shaped resisting strip 61 is located between the two bent hooks opposite to the second abutting portion 620 . The strip-shaped resisting strip 61 and the two hooks can be gap-fitted and can also interfere with each other. The slot 205 is provided with a protrusion 210 that engages with the hook portion of the holding portion 621. The protrusion 210 securely holds the holding portion 621 in the slot 205. Slot 205 and curved The resisting strip 62 holds the strip-shaped resisting strip 61 stably in the slot 205. The strip-shaped resisting strip 61 and the curved resisting strip 62 are extruded and have a smooth surface friction coefficient.
