Abstract
Abstract A socket for providing electrical connection between an IC and a mother board comprises an insulative housing defining a number of terminal passageways and a number of terminals received in the passageways. Each terminal includes a contact portion, a securing portion, an adjustment portion and a soldering portion. The contact portion is adapted to engage a pin of the IC. The securing portion is interferentially fit in the passageway for retaining the terminal therein. The feature of the invention lies in the resilient adjustment portion which can be easily and resiliently deformed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
An electrical socket for providing electrical connection between an IC and a mother board, comprising: an insulative housing defining a terminal passageway; a terminal in said passageway, the terminal further comprising: a contact portion having a curved structure for contacting a pin of the IC; a securing portion forming locking barbs on opposite sides thereof for interferingly fitting in said passageway; an adjustment portion configured to be a resilient structure; and a soldering portion; wherein the adjustment portion is moveable within the passageway, and wherein the adjustment portion is adapted to resiliently adjust a displacement of the soldering portion relative to the mother board due to differential thermal expansion between the socket and the mother board.
Claim 2
Dependent Claim
116 words
An electrical socket for providing electrical connection between an IC and a mother board, comprising: an insulative housing defining a terminal passageway; a terminal in said passageway, the terminal further comprising: a contact portion having a curved structure for contacting a pin of the IC; a securing portion forming locking barbs on opposite sides thereof for interferingly fitting in said passageway; an adjustment portion configured to be a resilient structure; and a soldering portion; wherein the adjustment portion is moveable within the passageway, and wherein the adjustment portion is adapted to resiliently adjust a displacement of the soldering portion relative to the mother board due to differential thermal expansion between the socket and the mother board.
Claim 3
Dependent Claim
23 words
The terminal as claimed in claim 1, wherein the securing portion of the terminal is wider than any other portion of the terminal.
Claim 4
Dependent Claim
20 words
The terminal as claimed in claim 1, wherein the contact portion of the terminal extends upwardly from the securing portion.
Claim 5
Dependent Claim
23 words
The terminal as claimed in claim 1, wherein the contact portion is U-shaped and extends from a top edge of the securing portion.
Claim 6
Dependent Claim
31 words
The terminal as claimed in claim 1, wherein each passageway includes a narrow section and a wide section, the wide section allowing the adjustment portion of the terminal to move therein.
Claim 7
Dependent Claim
18 words
The terminal as claimed in claim 1, wherein the adjustment portion of each terminal has a gracile structure.
Claim 8
Dependent Claim
18 words
The terminal as claimed in claim 1, wherein the adjustment portion of each terminal has a twisted structure.
Claim 9
Dependent Claim
18 words
The terminal as claimed in claim 1, wherein the adjustment portion of each terminal has a helical structure.
Claim 10
Dependent Claim
140 words
An electrical socket for providing electrical connection between an IC and a mother board, comprising: an insulative housing defining a top surface, a bottom surface opposite the top surface, and a plurality of terminal passageways extending between the top surface and the bottom surface; a plurality of terminals received within the corresponding passageways, respectively; each of said passageways including an upper narrow section and a lower wider section; and each of said terminals including a contact portion received within the upper narrow section, an adjustment portion below the contact portion received within said lower wider section, and a soldering portion at a bottom end thereof; whereby when the soldering portion is horizontally displaced due to different Coefficients of Thermal Expansion (CTE) between the socket and the mother board, the adjustment portion is resiliently laterally deflected within the lower wider section.
Claim 11
Dependent Claim
140 words
An electrical socket for providing electrical connection between an IC and a mother board, comprising: an insulative housing defining a top surface, a bottom surface opposite the top surface, and a plurality of terminal passageways extending between the top surface and the bottom surface; a plurality of terminals received within the corresponding passageways, respectively; each of said passageways including an upper narrow section and a lower wider section; and each of said terminals including a contact portion received within the upper narrow section, an adjustment portion below the contact portion received within said lower wider section, and a soldering portion at a bottom end thereof; whereby when the soldering portion is horizontally displaced due to different Coefficients of Thermal Expansion (CTE) between the socket and the mother board, the adjustment portion is resiliently laterally deflected within the lower wider section.
Claim 12
Dependent Claim
33 words
The socket as claimed in claim 9, wherein the adjustment portion is deflected toward a direction which is away from a pin of said IC engaged with the contact portion of the contact.
