Abstract
Abstract An aligning socket for an IC that provides an aligning bar that aligns and secures IC leads to the corresponding socket contacts (6), and where the bar has extensions or ears (42) that extend toward the row of IC leads (38). The ears have chamfered edges that, as the bar is forced toward the IC leads, guide the IC leads to mate with the socket contacts. For more fragile gull-winged leads, a rail 18 is provided to support the under side of the leads and the alignment bar ears are designed to fit over the ends of the rail. When the bar and socket contacts are forced toward the IC leads, the bar ears overlap the ends of the rail and force any mis-aligned IC leads to move such that alignment of the leads and the socket contacts is achieved.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package in a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads, (c) a discrete alignment bar that extends along the length of each lead row, and aligns each contact with a respective lead said bar having ears that matingly overlap the remote ends of said row of leads, (d) a rail of said base that fits between the bent portion of said leads and the package, said rail extending along said length of said row of leads, and said rail contacting said leads adjacent to the package to support the leads as the socket contacts make physical and electrical connections to said leads, said rail having a first and a second end constructed to mate with said ears.
Claim 2
Dependent Claim
196 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package in a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads, (c) a discrete alignment bar that extends along the length of each lead row, and aligns each contact with a respective lead said bar having ears that matingly overlap the remote ends of said row of leads, (d) a rail of said base that fits between the bent portion of said leads and the package, said rail extending along said length of said row of leads, and said rail contacting said leads adjacent to the package to support the leads as the socket contacts make physical and electrical connections to said leads, said rail having a first and a second end constructed to mate with said ears.
Claim 3
Dependent Claim
193 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads (c) a discrete alignment bar that extends along the length of each lead row, said bar having ears that matingly overlap the remote ends of said row of IC leads, where each said ear comprises an extension from said alignment bar into the row defined by said leads, where the extension has a first surface that faces generally said lead row, said first surface of the ears being chamfered such that as the alignment bar is driven toward said leads said first surfaces contact said leads and force said leads into positions defined between said chamfered surfaces to align each contact with a corresponding lead.
Claim 4
Dependent Claim
193 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads (c) a discrete alignment bar that extends along the length of each lead row, said bar having ears that matingly overlap the remote ends of said row of IC leads, where each said ear comprises an extension from said alignment bar into the row defined by said leads, where the extension has a first surface that faces generally said lead row, said first surface of the ears being chamfered such that as the alignment bar is driven toward said leads said first surfaces contact said leads and force said leads into positions defined between said chamfered surfaces to align each contact with a corresponding lead.
Claim 5
Dependent Claim
193 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads (c) a discrete alignment bar that extends along the length of each lead row, said bar having extensions or ears that matingly overlap the remote ends of said row of leads, wherein said bar includes a member formed substantially longitudinally parallel to said lead row, said bar having locators that accept the socket contacts and separate and secure the socket contacts to said bar, and where each socket contact has a protrusion constructed to matingly fit into the locators such that each contact remains separate from each other and where the contacts are fixed to said bar to align each contact with a corresponding lead.
Claim 6
Dependent Claim
193 words
A socket for ICs comprising: (a) a base with a cavity that accepts an IC package with leads extending away from said package a first direction for a distance and there said leads are bent and extend at about ninety degrees from said first direction, said leads defining rows, each said row having a length with remote ends, (b) a plurality of contacts constructed and arranged within the base, said contacts, formed in rows matching said lead rows and having extensions for making electrical connections to said leads (c) a discrete alignment bar that extends along the length of each lead row, said bar having extensions or ears that matingly overlap the remote ends of said row of leads, wherein said bar includes a member formed substantially longitudinally parallel to said lead row, said bar having locators that accept the socket contacts and separate and secure the socket contacts to said bar, and where each socket contact has a protrusion constructed to matingly fit into the locators such that each contact remains separate from each other and where the contacts are fixed to said bar to align each contact with a corresponding lead.
Claim 7
Dependent Claim
27 words
A socket as defined in claim 3 where the locators are grooves or through holes that are separated from each other by webs of said package material.
