IC socket

Claim 2

An IC socket comprising a socket board, an IC platform disposed on said socket board for movement upward and downward and adapted to carry an IC thereon, and a plurality of contacts arranged in array on said socket board portion around said IC platform, so that leads of said IC carried on said IC platform contact said plurality of contacts, wherein said IC socket further comprises a pivot shaft member allowed to penetrate a central portion of said IC platform, a pivotal operation portion for allowing a tip of a tool to engage therewith, being formed on a head portion of said pivot shaft member such that said pivotal operation portion is exposed on an upper surface side of said IC platform, a lower end portion of said shaft member being pivotably supported on said socket board portion right under said IC platform, said pivot shaft member being brought into connection with said IC platform through cam means adapted to guide said IC platform between a higher position and a lower position in accordance with a pivotal operation of said pivot shaft member, thereby adjusting an IC supporting height of said IC platform.

Claim 3

An IC socket as claimed in claim 1, wherein said head portion of said pivot shaft member is accommodated within an accommodation opening formed in said central portion of said IC platform.

Claim 4

An IC socket comprising a socket board, an IC platform disposed on said socket board for movement upward and downward and adapted to carry an IC thereon, and a plurality of contacts arranged in array on said socket board portion around said IC platform, so that leads of said IC carried on said IC platform contact said plurality of contacts, wherein said IC socket further comprises a pivot shaft member allowed to penetrate a central portion of said IC platform, a pivotal operation portion for allowing a tip of a tool to engage therewith, being formed on a head portion of said pivot shaft member such that said pivotal operation portion is exposed on an upper surface side of said IC platform, a lower end portion of said shaft member being in engagement with said IC platform such that said pivot shaft member is moved upward and downward following a movement of said IC platform, said lower end portion of said pivot shaft member being brought into connection with said socket board portion right under said IC platform through cam means adapted to guide said IC platform between a higher position and a lower position in accordance with a pivotal operation of said pivot shaft member, thereby adjusting an IC supporting height of said IC platform.

Claim 5

An IC socket comprising a socket board, an IC platform disposed on said socket board for movement upward and downward and adapted to carry an IC thereon, and a plurality of contacts arranged in array on said socket board portion around said IC platform, so that leads of said IC carried on said IC platform contact said plurality of contacts, wherein said IC socket further comprises a pivot shaft member allowed to penetrate a central portion of said IC platform, a pivotal operation portion for allowing a tip of a tool to engage therewith, being formed on a head portion of said pivot shaft member such that said pivotal operation portion is exposed on an upper surface side of said IC platform, a lower end portion of said shaft member being in engagement with said IC platform such that said pivot shaft member is moved upward and downward following a movement of said IC platform, said lower end portion of said pivot shaft member being brought into connection with said socket board portion right under said IC platform through cam means adapted to guide said IC platform between a higher position and a lower position in accordance with a pivotal operation of said pivot shaft member, thereby adjusting an IC supporting height of said IC platform.

Claim 6

An IC socket as claimed in claim 3, wherein said head portion of said pivot shaft member is accommodated within an accommodation opening formed in said central portion of said IC platform.
