Abstract
Abstract An electrical connecting device for disengageable connection to conductors of an electric component comprises an integrated circuit (IC) package having a plurality of leads in dual-in-line configuration. A socket included in such device comprises an insulative housing and first and second pluralities of contacts supported thereon arranged in laterally spaced, longitudinally corresponding positions. Each of the contacts has a first end portion selectively plated, with gold for example, for detachable connection to a conductor of the electric component. A second end of the contacts is selectively tin-plated and soldered to the leads of the IC package. The second end portion of each of the contacts is formed to have thereon at least two laterally spaced contact members, thereby providing for selective securement thereto of IC packages having different laterally spaced leads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
301 words
An electrical socket for disengageable connection to conductors of an electric component comprising: an elongate insulative housing for receiving an electric package having a plurality of conductive leads extending therefrom, said housing including a central portion having a plurality of apertures extending in spaced disposition longitudinally along the housing central portion, said housing including a lateral portion extending along said housing, two rows of openings extending longitudinally in said lateral portion, said rows of openings being laterally spaced from each other, said lateral portion having a plurality of laterally extending, longitudinally spaced recesses, each recess communicating with one opening of each row; and a plurality of conductive electrical contacts supported on said housing, each contact including a first end portion disposed in a respective one of said apertures for disengageable electrical engagement with a conductor of said electrical component and a second end portion having a projecting extent, each projecting extent lying in a respective recess in said housing lateral portion, there being on each projecting extent a pair of contact members in registry with a pair of said openings, one from each row, in said lateral portion, said contact members adapted for selective engagement with said leads of said electric package, said projecting extent of each contact second end portion comprising a generally flat surface, and said contact members each comprising a spring member biased to urge against a lead of said electric package, said spring members having been formed from said generally flat surface and being cantilevered and curved and projecting into respective ones of said openings of said housing, the unsupported distal ends of said spring members cooperating with an opposed spaced wall portion of the housing defining each opening to provide a resiliently expandable opening for receipt of one of said leads of the electric package therein.
Claim 2
Dependent Claim
301 words
An electrical socket for disengageable connection to conductors of an electric component comprising: an elongate insulative housing for receiving an electric package having a plurality of conductive leads extending therefrom, said housing including a central portion having a plurality of apertures extending in spaced disposition longitudinally along the housing central portion, said housing including a lateral portion extending along said housing, two rows of openings extending longitudinally in said lateral portion, said rows of openings being laterally spaced from each other, said lateral portion having a plurality of laterally extending, longitudinally spaced recesses, each recess communicating with one opening of each row; and a plurality of conductive electrical contacts supported on said housing, each contact including a first end portion disposed in a respective one of said apertures for disengageable electrical engagement with a conductor of said electrical component and a second end portion having a projecting extent, each projecting extent lying in a respective recess in said housing lateral portion, there being on each projecting extent a pair of contact members in registry with a pair of said openings, one from each row, in said lateral portion, said contact members adapted for selective engagement with said leads of said electric package, said projecting extent of each contact second end portion comprising a generally flat surface, and said contact members each comprising a spring member biased to urge against a lead of said electric package, said spring members having been formed from said generally flat surface and being cantilevered and curved and projecting into respective ones of said openings of said housing, the unsupported distal ends of said spring members cooperating with an opposed spaced wall portion of the housing defining each opening to provide a resiliently expandable opening for receipt of one of said leads of the electric package therein.
Claim 3
Dependent Claim
34 words
An electrical socket according to claim 1, wherein said first end portions contain material thereon different from material of said second end portions and suitable for disengagement with said conductors of said electric component.
Claim 4
Dependent Claim
22 words
An electrical socket according to claim 2, wherein said material is gold and is selectively disposed on said contact first end portions.
Claim 5
Dependent Claim
16 words
An electrical socket according to claim 1, wherein said recesses are electrically insulated from each other.
Claim 6
Dependent Claim
22 words
An electrical socket according to claim 1, wherein said contact first end portions extend substantially orthogonally relative to said contact projecting extents.
Claim 7
Dependent Claim
130 words
An electrical socket according to claim 1, wherein said housing includes a further plurality of spaced apertures extending longitudinally along said housing central portion and a further lateral portion having two further rows of openings extending longitudinally therein, said further lateral portion having a further plurality of recesses, each communicating with one opening of each such further row of openings and wherein said housing supports a further plurality of conductive electrical contacts each having a first end portion disposed in a respective further aperture and a second end portion having a projecting extend lying in a respective further recess, there being on each projecting extent of said further contacts a pair of contact members in registry with a pair of such further openings, one from each row of further openings.
Claim 8
Dependent Claim
39 words
An electrical socket according to claim 6, wherein said housing central portion depends from said housing lateral portions defining therewith a housing cross-section of generally T-shape, said central portion adapted for connection with a header device comprising said conductors.
