Patent ID: 7871283

Claim:
A two-point-contact type semiconductor package socket comprising: a socket base including a package rest on which a semiconductor package is to be placed that has gull-wing leads including at least a horizontal shoulder portion extending nearly horizontally from a main body and a vertical leg portion being bent nearly vertically from the horizontal shoulder portion; a cover member vertically movably attached on the socket base through an elastic member; a plurality of contacts each including at least a first contact piece capable of making contact, from above, with the horizontal shoulder portion of the gull-wing lead of the semiconductor package placed on the package rest, a second contact piece capable of making contact, laterally, with the vertical leg portion of the gull-wing lead of the semiconductor package and a fixed portion that is fixed in the socket base, and formed to advance onto the package rest or retract from the package rest due to vertical movement of the cover member; wherein, the package rest is formed with a dam wall that allows the gull-wing lead of the semiconductor package to lie thereover when the semiconductor package is placed on; the first contact piece and the second contact piece, of the contact, each have an elastic deforming portion that is elastically deformable to determine a contact pressure in a manner making contact with the gull-wing lead of the semiconductor package at a predetermined contact pressure; the timing of making contact the first contact piece and the second contact piece with the semiconductor package is delayed.
