Abstract
Abstract An IC socket includes a socket body which has an IC package placing area and resilient contacts around the IC package placing area, a cover pivotally attached to the socket body, a lock member pivotally attached to either the socket body or the cover for locking/unlocking the cover relative to the socket body, and IC lead pressing means movably mounted on the cover. The IC lead pressing means is provided integrally with pads for pressing the IC leads against the resilient contacts and is adapted to effect self-adjustment of its own movement so that the pads come into uniform contact with the IC leads.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
An IC socket comprising: a socket body having an IC package placing area formed on the upper central portion thereof and resilient contacts provided around said IC package placing area for allowing superposition of and contact with IC leads of an IC package, a cover having one end thereof attached pivotally to one end of said socket body so as to be opened and closed relative to the upper surface of said socket body, a lock member pivotally attached to one of the other end of said socket body and the other end of said cover for causing said socket body and said cover to be locked with and unlocked from each other, and IC lead pressing means provided integrally with pads for pressing the IC leads against said resilient contacts, movably mounted on said cover, and adapted to effect self-adjustment of its own movement so that said pads come into uniform contact with the IC leads immediately before said lock member locks said socket body and said cover and, when said lock member has locked said socket body and said cover, press the IC leads against said resilient contacts with high reliability.
Claim 2
Dependent Claim
193 words
An IC socket comprising: a socket body having an IC package placing area formed on the upper central portion thereof and resilient contacts provided around said IC package placing area for allowing superposition of and contact with IC leads of an IC package, a cover having one end thereof attached pivotally to one end of said socket body so as to be opened and closed relative to the upper surface of said socket body, a lock member pivotally attached to one of the other end of said socket body and the other end of said cover for causing said socket body and said cover to be locked with and unlocked from each other, and IC lead pressing means provided integrally with pads for pressing the IC leads against said resilient contacts, movably mounted on said cover, and adapted to effect self-adjustment of its own movement so that said pads come into uniform contact with the IC leads immediately before said lock member locks said socket body and said cover and, when said lock member has locked said socket body and said cover, press the IC leads against said resilient contacts with high reliability.
Claim 3
Dependent Claim
22 words
An IC socket according to claim 1, wherein said IC lead pressing means is swingably attached to said cover with a pin.
Claim 4
Dependent Claim
31 words
An IC socket according to claim 1, wherein said IC lead pressing means is attached to said cover with a universal joint so that said IC lead pressing means moves omnidirectionally.
Claim 5
Dependent Claim
37 words
An IC socket according to claim 1, wherein said IC lead pressing means is loosely fitted within a space defined by the inner surface of said cover and the IC package placing area of said socket body.
Claim 6
Dependent Claim
17 words
An IC socket according to claim 1, wherein said IC lead pressing means comprises a single member.
Claim 7
Dependent Claim
18 words
An IC socket according to claim 1, wherein said IC lead pressing means comprises a plurality of members.
