Abstract
Abstract Miniature socket receptacles employing multiple, flexed legs for contacting an inserted male pin include means for preventing the legs from being overstressed by misalignment of the male pin causing a force transverse to the longitudinal axis of the receptacle. The means can be right angled flanges formed at the terminal portion of the legs or a constriction formed in the throat of the receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
An elongated, electrical contact receiving, socket receptable formed for insertion and retention in a receiving aperture in a printed circuit board, said socket receptacle comprising: a relatively thin, flexible, hollow body having a longitudinal axis and having a circumferential extent of greater than 180° but less than 360°; said body having a proximal portion having a given external diameter sized to fit said receiving aperture; and a distal portion having an internal diameter less than said given external diameter, said distal portion being formed to provide at least three legs which are substantially parallel to said longitudinal axis, each of said legs being formed to provide a desired amount of stress; said socket receptacle including means to prevent said at least three legs from being overstressed by the application of a force applied thereto in a direction transverse to said longitudinal axis, said means to prevent said at least three legs from being overstressed comprising a flange formed on the terminal end of each of said at least legs, said flange extending in a direction substantially normal to said longitudinal axis and away from said longitudinal axis.
Claim 2
Dependent Claim
187 words
An elongated, electrical contact receiving, socket receptable formed for insertion and retention in a receiving aperture in a printed circuit board, said socket receptacle comprising: a relatively thin, flexible, hollow body having a longitudinal axis and having a circumferential extent of greater than 180° but less than 360°; said body having a proximal portion having a given external diameter sized to fit said receiving aperture; and a distal portion having an internal diameter less than said given external diameter, said distal portion being formed to provide at least three legs which are substantially parallel to said longitudinal axis, each of said legs being formed to provide a desired amount of stress; said socket receptacle including means to prevent said at least three legs from being overstressed by the application of a force applied thereto in a direction transverse to said longitudinal axis, said means to prevent said at least three legs from being overstressed comprising a flange formed on the terminal end of each of said at least legs, said flange extending in a direction substantially normal to said longitudinal axis and away from said longitudinal axis.
Claim 3
Dependent Claim
37 words
The socket receptable of claim 1 wherein said means to prevent said at least three legs from being overstressed comprises at least one constriction formed in said proximal portion, said constriction extending inwardly toward said longitudinal axis.
Claim 4
Dependent Claim
20 words
The socket receptacle of claim 2 wherein said constriction is laterally continuous about the interior circumference of said proximal portion.
Claim 5
Dependent Claim
23 words
The socket receptacle of claim 2 wherein said constriction is segmented and the number of segments is equal in number to said legs.
Claim 6
Dependent Claim
14 words
The socket receptacle of claim 4 wherein said segments are aligned with said legs.
