Abstract
Abstract An IC socket, capable of being applied to an IC device having short lead pins and ensuring reliable contact with the lead pins used, comprises contacts each having a first contact element that is substantially fixed and a second contact element that is elastically deformable, and an actuator for moving the second contact elements of the contacts. The second contact elements have their centers formed as engaging means for engaging with the actuator, and their portions near the surface of a socket body are formed as contacting means to be brought into contact with lead pins of an IC device. The second contact elements are located close to the first contact elements. When an IC device is inserted, the actuator separates the second contact elements from the first contact elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
An IC socket comprising a socket body having a surface and a plurality of holes arranged on said surface at a predetermined pattern, a contact arranged in each of the holes and comprising a first substantially fixed contact element and a second elastically deformable contact element for holding therebetween a lead pin of an IC device, and an actuator for moving the second contact element of said contact, wherein said second contact element comprises at an intermediate point thereof, an engaging means for engaging with said actuator, and a contacting means at a position on the side of said second contact element spaced from said intermediate point for contacting a lead pin of an IC device, and wherein said second contact element is arranged close to said first contact element and said actuator causes said second contact element to be spaced at one end from said first contact element when the IC device is inserted in the IC socket, and wherein said first and second contact elements comprise oppositely disposed metal elements; said second contact element and said actuator being located on opposite sides of said first contact element; said first contact element having a cavity at a position facing the second contact element; said second contact element and said actuator being able to engage with each other via the cavity of said first contact element.
Claim 2
Dependent Claim
226 words
An IC socket comprising a socket body having a surface and a plurality of holes arranged on said surface at a predetermined pattern, a contact arranged in each of the holes and comprising a first substantially fixed contact element and a second elastically deformable contact element for holding therebetween a lead pin of an IC device, and an actuator for moving the second contact element of said contact, wherein said second contact element comprises at an intermediate point thereof, an engaging means for engaging with said actuator, and a contacting means at a position on the side of said second contact element spaced from said intermediate point for contacting a lead pin of an IC device, and wherein said second contact element is arranged close to said first contact element and said actuator causes said second contact element to be spaced at one end from said first contact element when the IC device is inserted in the IC socket, and wherein said first and second contact elements comprise oppositely disposed metal elements; said second contact element and said actuator being located on opposite sides of said first contact element; said first contact element having a cavity at a position facing the second contact element; said second contact element and said actuator being able to engage with each other via the cavity of said first contact element.
Claim 3
Dependent Claim
42 words
An IC socket according to claim 1, wherein said second contact element comprises a projection at said intermediate point bent so that it projects past the first contact element, and said actuator is engagable with said projection of said second contact element.
Claim 4
Dependent Claim
39 words
An IC socket according to claim 1, wherein said second contact element comprises a projection bent so that it projects into the cavity of the first contact element, and said actuator engages said projection of said second contact element.
Claim 5
Dependent Claim
31 words
An IC socket according to claim 1, wherein said first contact element has at said one end thereof, a projection for making contact with a lead pin of an IC device.
Claim 6
Dependent Claim
31 words
An IC socket according to claim 2, wherein said first contact element has at said one end thereof, a projection for making contact with a lead pin of an IC device.
