Abstract
Abstract Contacts and receiving sleeves within a discrete connector insulator are sized to permit the contacts to be inserted into the sleeves of the insulator and secured therein by a small force applied to the top of the contacts. Receiving sleeves formed in the insulator are constructed to permit the contacts to be top loaded therein and lightly forced over detent means comprise a downwardly facing shoulder having an upper body portion tapering to the edge of the shoulder region complementarily formed for abutting engagement against the insulator shoulder for securing the contact in the insulator. The contacts are inserted into the insulator simultaneously while depending from a common support strip for facilitating assembly of the connector. The connector receives and electrically connects a mating printed circuit board through insertion thereof into the upper part of the insulative housing. The assembled discrete connector of the present invention permits removal of individual contacts from the connector for repair by the insertion of a contact receiving tool into the contact sleeve in the insulator for moving the collar portion of the contact laterally away from the insulator detent shoulder and permitting its upward removal therefrom.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
224 words
An improved discrete electrical connector of the type having a plurality of contacts received within an insulative housing for mounting upon a planar substrate, wherein the improvement comprises: an insulative housing having sleeves formed therethrough and open at the top for permitting the contacts to be inserted therein, said sleeves being formed with pairs of spaced detent shoulders, each having an upwardly facing tapering configuration to facilitate movement of a contact collar portion downwardly past said detent shoulders, said detent shoulders being transversely spaced to define an open area therebetween and including a downwardly facing ledge portion thereunder for retaining a contact collar portion beneath said detent shoulders, said housing also including a lower inside wall terminating in a generally horizontal edge to define a line of flexure for contacts inserted into said sleeves; and contacts positioned in each of said sleeves, each contact having a generally transversely extending collar portion intermediate thereof and a necked portion beneath said collar defining a flexure section thereacross for permitting transverse elastic flexure of the contact during positioning of said contact collar portions beneath said detent shoulders, said necked portion also defining a line of plastic deformation flexure adjacent said generally horizontal edge to permit permanent bending of a contact from beneath said detent shoulders for removal of a contact from a sleeve within the insulative housing.
Claim 2
Dependent Claim
224 words
An improved discrete electrical connector of the type having a plurality of contacts received within an insulative housing for mounting upon a planar substrate, wherein the improvement comprises: an insulative housing having sleeves formed therethrough and open at the top for permitting the contacts to be inserted therein, said sleeves being formed with pairs of spaced detent shoulders, each having an upwardly facing tapering configuration to facilitate movement of a contact collar portion downwardly past said detent shoulders, said detent shoulders being transversely spaced to define an open area therebetween and including a downwardly facing ledge portion thereunder for retaining a contact collar portion beneath said detent shoulders, said housing also including a lower inside wall terminating in a generally horizontal edge to define a line of flexure for contacts inserted into said sleeves; and contacts positioned in each of said sleeves, each contact having a generally transversely extending collar portion intermediate thereof and a necked portion beneath said collar defining a flexure section thereacross for permitting transverse elastic flexure of the contact during positioning of said contact collar portions beneath said detent shoulders, said necked portion also defining a line of plastic deformation flexure adjacent said generally horizontal edge to permit permanent bending of a contact from beneath said detent shoulders for removal of a contact from a sleeve within the insulative housing.
Claim 3
Dependent Claim
45 words
The improved discrete connector as set forth in claim 1 wherein said upper mating portion of said contact includes a bifurcated tine configuration, each of said tines having an outwardly extending flange portion seated against a longitudinal section of said sleeve of said insulative housing.
Claim 4
Dependent Claim
40 words
The improved discrete connector as set forth in claim 2 wherein said longitudinal section of said sleeve of said insulative housing is comprised of an orthogonal wall flange receiving said contact flange thereagainst and preloading said contact within said sleeve.
Claim 5
Dependent Claim
53 words
The improved discrete connector as set forth in claim 1 wherein said collar portion is comprised of a pair of outwardly extending shoulders including an inwardly facing body portion having a downwardly facing taper constructed for slidably engaging said upwardly facing taper of said detent shoulders of said sleeves during contact insertion therein.
Claim 6
Dependent Claim
30 words
The improved discrete connector as set forth in claim 1 wherein said sleeves of the insulative housing are formed in paired rows for the reception of card edge contacts therein.
Claim 7
Dependent Claim
184 words
A discrete electrical connector comprising: an insulative housing including an outer shell having side walls open at the top and a plurality of sleeves formed therethrough and spaced from one another for axial alignment with apertures in a mounting substrate, each of said sleeves including a lower inside wall terminating in a generally horizontal edge and a pair of detent shoulders having an upwardly facing tapered body portion and downwardly facing shoulders at the lower end thereof; and contacts positioned within each of said sleeves and including an intermediate transversely extending collar portion having an upwardly facing shoulder in abutting engagement with the downwardly facing detent shoulders at the lower end of the housing for resisting upward movement of the contact, said contacts each including a necked portion beneath said collar portion defining a flexure section thereacross for permitting transverse elastic flexure of the contact during positioning of said contact collar portion beneath said downwardly facing detent shoulders, said necked portion also defining a line of deformation flexure adjacent said generally horizontal edge to permit bending of a contact from beneath said detent shoulders.
Claim 8
Dependent Claim
184 words
A discrete electrical connector comprising: an insulative housing including an outer shell having side walls open at the top and a plurality of sleeves formed therethrough and spaced from one another for axial alignment with apertures in a mounting substrate, each of said sleeves including a lower inside wall terminating in a generally horizontal edge and a pair of detent shoulders having an upwardly facing tapered body portion and downwardly facing shoulders at the lower end thereof; and contacts positioned within each of said sleeves and including an intermediate transversely extending collar portion having an upwardly facing shoulder in abutting engagement with the downwardly facing detent shoulders at the lower end of the housing for resisting upward movement of the contact, said contacts each including a necked portion beneath said collar portion defining a flexure section thereacross for permitting transverse elastic flexure of the contact during positioning of said contact collar portion beneath said downwardly facing detent shoulders, said necked portion also defining a line of deformation flexure adjacent said generally horizontal edge to permit bending of a contact from beneath said detent shoulders.
Claim 9
Dependent Claim
