Abstract
Abstract An IC socket has a socket substrate, an IC press cover pivotally attached to one end of the socket substrate through a shaft, and a lock member pivotally attached to the other end of the socket substrate through a shaft and adapted to engage with and disengage from a free end of the IC press cover. The improvement is characterized in that one end of the socket substrate is formed with a lock member pivot hole for inserting therein the shaft for the lock member adjacent to a press cover pivot hole for inserting therein the shaft for the IC press cover, and the other end of the socket substrate is formed with a press cover pivot hole for inserting therein the shaft for the IC press cover adjacent to a lock member pivot hole for inserting therein the shaft for the lock member. The two pivot holes formed in the above-mentioned one end of the socket substrate are arranged symmetrically with the two pivot holes formed in the other end of the socket substrate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
An IC socket comprising: a socket substrate having first and second opposing ends, a horizontal upper face, first and second vertical side faces, first and second press cover pivot holes (13, 17) formed horizontally through said first and second ends, respectively, and first and second lock member pivot holes (16, 14) formed horizontally through said first and second ends, respectively, said first and second press cover pivot holes (13, 17) being aligned vertically with said first and second lock member pivot holes (16, 14), respectively; a press cover pivot shaft selectively removably inserted through one of said first and second press cover pivot holes (13, 17); a lock member pivot shaft selectively removably inserted through the one of said first and second lock member pivot holes (16, 14) formed through the one of said first and second ends opposite to the one of said first and second ends through which said press cover pivot shaft is inserted; a press cover pivotably mounted about said press cover pivot shaft for movement between a closed position in which said press cover is in overlying relation to said socket substrate and an open position; and a lock member pivotably mounted about said lock member pivot shaft for movement between a locking position in which said lock member can lock said press cover in said closed position, and an unlocking position.
Claim 2
Dependent Claim
227 words
An IC socket comprising: a socket substrate having first and second opposing ends, a horizontal upper face, first and second vertical side faces, first and second press cover pivot holes (13, 17) formed horizontally through said first and second ends, respectively, and first and second lock member pivot holes (16, 14) formed horizontally through said first and second ends, respectively, said first and second press cover pivot holes (13, 17) being aligned vertically with said first and second lock member pivot holes (16, 14), respectively; a press cover pivot shaft selectively removably inserted through one of said first and second press cover pivot holes (13, 17); a lock member pivot shaft selectively removably inserted through the one of said first and second lock member pivot holes (16, 14) formed through the one of said first and second ends opposite to the one of said first and second ends through which said press cover pivot shaft is inserted; a press cover pivotably mounted about said press cover pivot shaft for movement between a closed position in which said press cover is in overlying relation to said socket substrate and an open position; and a lock member pivotably mounted about said lock member pivot shaft for movement between a locking position in which said lock member can lock said press cover in said closed position, and an unlocking position.
Claim 3
Dependent Claim
39 words
An IC socket as recited in claim 1, wherein each of said first and second press cover pivot holes and said first and second lock member pivot holes extend through both of said first and second vertical side faces.
Claim 4
Dependent Claim
29 words
An IC socket as recited in claim 1, wherein said first and second press cover pivot holes are aligned above said first and second lock member pivot holes, respectively.
Claim 5
Dependent Claim
50 words
An IC socket as recited in claim 1, wherein said lock member includes a hook shaped claw portion; and said press cover includes a retaining portion for engagement with said claw portion when said press cover is in said closed position and said lock member is in said locking position.
Claim 6
Dependent Claim
20 words
An IC socket as recited in claim 4, further comprising means for biasing said lock member toward its locking position.
Claim 7
Dependent Claim
45 words
An IC socket as recited in claim 5, wherein said lock member also includes a push-down operating portion extending away from said socket substrate for causing said lock member to pivot toward said unlocking position when a downward force is applied to said operating portion.
Claim 8
Dependent Claim
27 words
An IC socket as recited in claim 6, wherein said operating portion of said lock member is offset laterally from a lateral center of said socket substrate.
