Abstract
Abstract This invention relates to an IC socket, and more particularly an IC socket comprising a socket base plate having contacts on which the IC lead wires of the mounted IC are mounted and contacted, a pushing cover to be closed against the socket base plate through IC, and a pushing member for pressing the IC lead wires against the contacts in response to the closing operation of the pushing cover. Means for making a positive prevention of the displacements of the pushing positions of the IC lead wires by the pushing member is provided, that is, the pushing cover is rotatably supported on the socket base plate, the pushing member is supported on the socket base plate separate from the pushing cover and the pivoting shaft is supported in a longitudinal hole extending in a vertical direction and the pushing cover can be rotated and moved up and down vertically.

Claim 1
Independent Claim
215 words
An IC socket comprising: a socket base plate having contacts to which IC lead wires of an IC to be mounted are contacted and mounted; a pushing cover adapted to be pushed closed against said socket base plate with an IC therebetween; and a pushing member for pressing the IC lead wires against said contacts in response to a closing operation of said pushing cover, said pushing cover being rotatably supported on said socket base plate, said pushing member supported on said socket base plate separately from said pushing cover, said pushing cover adapted to rotate and move up and down vertically by means of a structure for supporting a pivoting shaft around which said pushing member pivots, in a longitudinal hole extending in a vertical direction; wherein said pushing member comprises a supporting part for supporting said pushing member in rotation and translation; said IC socket further comprising a spring member for biasing said pushing cover in a rotating opening direction arranged near said supporting part of said pushing cover for said socket base plate, and a spring member for biasing said pushing member in a rotating opening direction and an upward or downward direction in said longitudinal hole is arranged near said supporting part of said pushing member for said socket base plate.

Dependent Claim
215 words
An IC socket comprising: a socket base plate having contacts to which IC lead wires of an IC to be mounted are contacted and mounted; a pushing cover adapted to be pushed closed against said socket base plate with an IC therebetween; and a pushing member for pressing the IC lead wires against said contacts in response to a closing operation of said pushing cover, said pushing cover being rotatably supported on said socket base plate, said pushing member supported on said socket base plate separately from said pushing cover, said pushing cover adapted to rotate and move up and down vertically by means of a structure for supporting a pivoting shaft around which said pushing member pivots, in a longitudinal hole extending in a vertical direction; wherein said pushing member comprises a supporting part for supporting said pushing member in rotation and translation; said IC socket further comprising a spring member for biasing said pushing cover in a rotating opening direction arranged near said supporting part of said pushing cover for said socket base plate, and a spring member for biasing said pushing member in a rotating opening direction and an upward or downward direction in said longitudinal hole is arranged near said supporting part of said pushing member for said socket base plate.
Claim 3
Dependent Claim
70 words
An IC socket according to claim 1, wherein said pushing member comprises a supporting part for supporting said pushing member in rotation and translation; said IC socket further comprising a spring member for biasing said pushing member in a rotating opening direction and an upward direction of a vertical moving-up or -down movement, said spring member arranged near said supporting part of said pushing member for said socket base plate.
Claim 4
Dependent Claim
103 words
An IC socket according to claim 1 further comprising a spring member for biasing said pushing cover in a rotating opening direction arranged near a supporting part of said pushing cover for said socket base plate, a spring member for biasing said pushing member in an upward direction of the vertical moving-up or -down movement is arranged near a supporting part of said pushing member for said socket base plate, and an engaging member for making an integral formation of a rotating opening operation of said pushing cover and a rotating opening operation of said pushing member is arranged at said pushing cover.
Claim 5
Dependent Claim
29 words
An IC socket according to claim 1 in which guides for preventing a width-wise displacement of said pushing member are arranged on the upper surface of the base plate.
Claim 6
Dependent Claim
16 words
An IC socket according to claim 4 in which said guides comprise opposing flat L-shaped pieces.
Claim 7
Dependent Claim
51 words
An IC socket according to claim 4 in which said guides comprise concavities and projections, arranged in the upper surface of said socket base plate and the inner surface of said pushing member, respectively, said projections and concavities adapted to fit with each other further comprising a spring member for biasing.
Claim 8
Dependent Claim
42 words
An IC socket according to claim 1 in which the inner surface of said pushing cover is provided with a raised projection abutted against the upper surface of said pushing member to push said pushing member when said pushing cover is closed.
Claim 9
Dependent Claim
15 words
An IC socket according to claim 7 wherein said projection comprises a leaf spring member.
Claim 10
Dependent Claim
40 words
An IC socket according to claim 1, wherein said pushing member comprises a supporting part for supporting said pushing member in translation; said IC socket further comprising a spring member for upwardly biasing said pushing member at said supporting part.
