Abstract
Abstract An IC socket including a socket board having a plurality of contacts on which an IC is to be placed, an IC pressing cover open- and closeably pivotally connected to the socket board, and an IC loading table with the IC loaded thereon, the table being disposed on the socket board and adapted to facilitate a proper contact between the IC and the contacts, the IC socket further including a positioning projection of a generally V-shape formed on the side of the IC pressing cover and a positioning valley of a generally V-shape formed on the side of the IC loading table, the projection and valley being disposed in such a manner as to be corresponded to each other, the generally V-shaped positioning projection being held into the generally V-shaped valley when the IC pressing cover is closed, so that a relative position of the IC pressing cover can be maintained with respect to the IC loading table and IC.

Total Claims: 12
Claim 1
Independent Claim
223 words
An IC socket, comprising: a substantially rectangular-shaped socket board having a plurality of contacts on which an IC is to be placed; a substantially rectangular-shaped IC pressing cover openably and closably pivotally connected to said socket board; and an IC loading table adapted to have an IC loaded thereon, said table being disposed on said socket board and adapted to facilitate a proper contact between the contacts of an IC and said socket board contacts; one of said loading table and said pressing cover having at least two positioning projections of a generally V-shape thereon, one at each of two diagonally opposite corners of the socket board and pressing cover, and the other of said loading table and said pressing cover having at least two positioning valleys of a generally V-shape therein at corresponding diagonally opposite corners, said projections and valleys being in mating opposed relation to each other, said projections having a ridge line at the apex thereof and said valleys having a bottom line at the apex thereof, said ridge lines and bottom lines lying at an angle to the sides of said loading table and pressing cover, whereby when said pressing cover is closed, the projections are urged into said valleys for bringing the pressing cover and loading table into register with respect to an IC on the loading table.
Claim 2
Dependent Claim
223 words
An IC socket, comprising: a substantially rectangular-shaped socket board having a plurality of contacts on which an IC is to be placed; a substantially rectangular-shaped IC pressing cover openably and closably pivotally connected to said socket board; and an IC loading table adapted to have an IC loaded thereon, said table being disposed on said socket board and adapted to facilitate a proper contact between the contacts of an IC and said socket board contacts; one of said loading table and said pressing cover having at least two positioning projections of a generally V-shape thereon, one at each of two diagonally opposite corners of the socket board and pressing cover, and the other of said loading table and said pressing cover having at least two positioning valleys of a generally V-shape therein at corresponding diagonally opposite corners, said projections and valleys being in mating opposed relation to each other, said projections having a ridge line at the apex thereof and said valleys having a bottom line at the apex thereof, said ridge lines and bottom lines lying at an angle to the sides of said loading table and pressing cover, whereby when said pressing cover is closed, the projections are urged into said valleys for bringing the pressing cover and loading table into register with respect to an IC on the loading table.
Claim 3
Dependent Claim
24 words
An IC socket as claimed in claim 1 wherein said projections are on said pressing cover and said valleys are in said socket board.
Claim 4
Dependent Claim
24 words
An IC socket as claimed in claim 1 wherein said projections are on said socket board and said valleys are in said pressing cover.
Claim 5
Dependent Claim
205 words
An IC socket, comprising: a substantially rectangular-shaped socket board having a plurality of contacts on which an IC is to be placed; a substantially rectangular-shaped IC pressing cover openably and closably pivotally connected to said socket board; and an IC pressing member movably attached to said pressing cover for movement in the IC pressing direction; one of said socket board and said pressing member having at least two positioning projections of a generally V-shape thereon, one at each of two diagonally opposite corners of the socket board and pressing cover, and the other of said socket board and said pressing member having at least two positioning valleys of a generally V-shape therein at corresponding diagonally opposite corners, said projections and valleys being in mating opposed relation to each other, said projections having a ridge line at the apex thereof and said valleys having a bottom line at the apex thereof, said ridge lines and bottom lines lying at an angle to the sides of said socket board and pressing member, whereby when said pressing cover is closed, the projections are urged into said valleys for bringing the pressing cover and pressing member and socket board into register with respect to an IC in the socket.
Claim 6
Dependent Claim
205 words
An IC socket, comprising: a substantially rectangular-shaped socket board having a plurality of contacts on which an IC is to be placed; a substantially rectangular-shaped IC pressing cover openably and closably pivotally connected to said socket board; and an IC pressing member movably attached to said pressing cover for movement in the IC pressing direction; one of said socket board and said pressing member having at least two positioning projections of a generally V-shape thereon, one at each of two diagonally opposite corners of the socket board and pressing cover, and the other of said socket board and said pressing member having at least two positioning valleys of a generally V-shape therein at corresponding diagonally opposite corners, said projections and valleys being in mating opposed relation to each other, said projections having a ridge line at the apex thereof and said valleys having a bottom line at the apex thereof, said ridge lines and bottom lines lying at an angle to the sides of said socket board and pressing member, whereby when said pressing cover is closed, the projections are urged into said valleys for bringing the pressing cover and pressing member and socket board into register with respect to an IC in the socket.
