Patent ID: 7632106

Claim:
An IC socket to be mounted on a circuit board, comprising a base board having an upper wall and a lower wall face to face with each other to surround together a resilient member receiving area and having a curved surface formed integral with the base board and protruding to the resilient member receiving area, the base board being mounted on a circuit board, the upper wall located at the side of an IC with leads loaded attachably, the lower wall located at the side of the circuit board, and at least the upper wall of the upper wall and the lower wall farming a plurality of slots aligned corresponding to each lead of the IC, a plurality of contacts comprising a contact main body, a first contact portion formed on one end thereof and the lead of the IC coming in contact with the end, a second contact portion formed on another end thereof and extending in one direction and coming in contact with a circuit lead of the circuit board, and a compressing portion provided protrusively on an opposite side to the extending direction of the second contact portion of the contact main body, and a resilient member comprising one resilient body in the shape of a string or a column located in the resilient member receiving area and holding elastically and aligning the contact, the first contact portion of the contact being inserted in the slot of the upper wall and exposed from a surface of the upper wall, and wherein the curved surface is sidably fit to the contact main body, and the compressing portion of each contact compresses the one resilient body in contact elastically with the resilient member keeping the contact a standby posture and compresses the resilient member when the first contact portion comes in contact with and is compressed by the lead of the IC, and obtaining a contact pressure between the first contact portion and the lead of the IC and a contact pressure between the second contact portion and the circuit lead of the circuit board.
