Abstract
Abstract A contact of an electric part socket has a first spring portion, a second spring portion spaced apart from the first spring portion but connected to it at both basal and distal ends thereof, a terminal portion leading to the connecting portion between the basal ends and adapted to be brought into contact with a wiring board or the like, and a contact portion formed on the connecting portion between the distal ends and adapted to be brought into contact with a terminal of an electric part to be engaged on it. The first and second spring portions are flexed about the connecting portion between the basal ends in order to displace the contact portion downward. The contact portion is pressure contacted with the terminal of the electric part mounted on it by reaction of the first and second spring portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A contact for use in a socket for receiving an electric part, said contact comprising: a first spring portion; a second spring portion spaced apart from said first spring portion; a basal end connecting portion connected between basal ends of said spring portions: a distal end connecting portion connected between distal ends of said spring portions and extending along a connecting line perpendicular to a median line between said spring portions; a terminal portion connected to the basal end connection portion and adapted to be brought into contact with a wiring board or the like; and a contact end portion on said distal end connecting portion and extending from said distal end connecting portion in the direction of said connecting line and perpendicular to said median line and having a contact point on the free end thereof spaced from said distal end connecting portion in the direction of said connecting line and adapted to be contacted by a terminal of an electric part inserted into the socket for moving said contact end portion substantially in the direction of said connecting line toward said distal end connecting portion for distorting said first and second spring portions and completing electrical contact between said contact point and the terminal under the resiliency of the distorted first and second spring portions, whereby said contact point moves substantially parallel to said connecting line.
Claim 2
Dependent Claim
228 words
A contact for use in a socket for receiving an electric part, said contact comprising: a first spring portion; a second spring portion spaced apart from said first spring portion; a basal end connecting portion connected between basal ends of said spring portions: a distal end connecting portion connected between distal ends of said spring portions and extending along a connecting line perpendicular to a median line between said spring portions; a terminal portion connected to the basal end connection portion and adapted to be brought into contact with a wiring board or the like; and a contact end portion on said distal end connecting portion and extending from said distal end connecting portion in the direction of said connecting line and perpendicular to said median line and having a contact point on the free end thereof spaced from said distal end connecting portion in the direction of said connecting line and adapted to be contacted by a terminal of an electric part inserted into the socket for moving said contact end portion substantially in the direction of said connecting line toward said distal end connecting portion for distorting said first and second spring portions and completing electrical contact between said contact point and the terminal under the resiliency of the distorted first and second spring portions, whereby said contact point moves substantially parallel to said connecting line.
Claim 3
Dependent Claim
23 words
A contact as claimed in claim 1 in which said first and second spring portions are curved in opposite directions from each other.
Claim 4
Dependent Claim
21 words
A contact as claimed in claim 1 in which said first and second spring portions are in a generally parallel relation.
Claim 5
Dependent Claim
23 words
A contact as claimed in claim 1 or 3 in which said first and second spring portions are substantially the same in length.
Claim 6
Dependent Claim
247 words
A contact for use in a socket for receiving an electric part, said contact comprising: a first spring portion; a second spring portion spaced apart from said first spring portion and having a different length from said first spring portion; a basal end connecting portion connected between basal ends of said spring portions; a distal end connecting portion connected between distal ends of said spring portions and extending along a connecting line perpendicular to a median line between said spring portions; a terminal portion connected to the basal end connection portion and adapted to be brought into contact with a wiring board or the like; and a contact end portion on said distal end connecting portion and extending from said distal end connecting portion in the direction of said connecting line and perpendicular to said median line and having a contact point on the free end thereof spaced from said distal end connecting portion in the direction of said connecting line and adapted to be contacted by a terminal of an electric part inserted into the socket for moving said contact end portion substantially in the direction of said connecting line toward said distal end connecting portion for distorting said first and second spring portions and completing electrical contact between said contact point and the terminal under the resiliency of the distorted first and second spring portions, and for also moving said contact point with a component of motion in a direction laterally of said connecting line.
Claim 7
Dependent Claim
247 words
A contact for use in a socket for receiving an electric part, said contact comprising: a first spring portion; a second spring portion spaced apart from said first spring portion and having a different length from said first spring portion; a basal end connecting portion connected between basal ends of said spring portions; a distal end connecting portion connected between distal ends of said spring portions and extending along a connecting line perpendicular to a median line between said spring portions; a terminal portion connected to the basal end connection portion and adapted to be brought into contact with a wiring board or the like; and a contact end portion on said distal end connecting portion and extending from said distal end connecting portion in the direction of said connecting line and perpendicular to said median line and having a contact point on the free end thereof spaced from said distal end connecting portion in the direction of said connecting line and adapted to be contacted by a terminal of an electric part inserted into the socket for moving said contact end portion substantially in the direction of said connecting line toward said distal end connecting portion for distorting said first and second spring portions and completing electrical contact between said contact point and the terminal under the resiliency of the distorted first and second spring portions, and for also moving said contact point with a component of motion in a direction laterally of said connecting line.
