Abstract
Abstract A circuit board socket comprises an inner spring means telescopingly disposed within a tubular housing about which is fitted an outer spring means, to provide a composite assembly arranged to be press fitted into a suitable socket receiving aperture in a circuit board or the like with the inner spring means having converging leg portions adapted to securely engage a terminal pin inserted therewithin. The outer spring means is provided with a sleeve portion encircling the housing and terminating selectively arched and outwardly bowed finger portions adapted to engage either the plated or unplated interior of the circuit board aperture to provide mechanical and electrical engagement therewith.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
A circuit board socket comprising, in combination: a resilient tubular inner spring means having converging leg portions adjacent one end thereof and outwardly extending tab means adjacent the other end thereof, said inner spring means being arranged to resiliently engage a terminal pin inserted therewithin; an elongate tubular housing closed at one end and having a flared portion adjacent the other end, said inner spring means being telescopingly disposed within said housing, said inner spring means tab means being coupled to said housing flared portion to provide electrical engagement therebetween; and a discrete outer spring means having a hollow sleeve portion and diverging resilient finger portions extending outwardly from said sleeve portion adjacent one end thereof, said outer spring means sleeve portion being telescopingly disposed about the exterior of said housing and tightly fitted thereabout, said finger portions being arranged to engage the inner surface of a socket receiving aperture in a circuit board to support said socket therewithin.
Claim 2
Dependent Claim
159 words
A circuit board socket comprising, in combination: a resilient tubular inner spring means having converging leg portions adjacent one end thereof and outwardly extending tab means adjacent the other end thereof, said inner spring means being arranged to resiliently engage a terminal pin inserted therewithin; an elongate tubular housing closed at one end and having a flared portion adjacent the other end, said inner spring means being telescopingly disposed within said housing, said inner spring means tab means being coupled to said housing flared portion to provide electrical engagement therebetween; and a discrete outer spring means having a hollow sleeve portion and diverging resilient finger portions extending outwardly from said sleeve portion adjacent one end thereof, said outer spring means sleeve portion being telescopingly disposed about the exterior of said housing and tightly fitted thereabout, said finger portions being arranged to engage the inner surface of a socket receiving aperture in a circuit board to support said socket therewithin.
Claim 3
Dependent Claim
26 words
A circuit board socket as defined in claim 1 wherein said outer spring means sleeve portion has a generally uniform interior transverse dimension throughout its length.
Claim 4
Dependent Claim
40 words
A circuit board socket as defined in claim 1 wherein each of said outer spring means finger portions is selectively arched about its longitudinal axis to provide a concave interior surface facing the adjacent exterior surface of said tubular housing.
Claim 5
Dependent Claim
26 words
A circuit board socket as defined in claim 1 wherein each of said outer spring means finger portions is selectively bowed outwardly generally intermediate its length.
Claim 6
Dependent Claim
55 words
A circuit board socket as defined in claim 1 wherein said tubular housing has a generally circular cross section and each of said outer spring means finger portions is selectively arched about its longitudinal axis to provide a concave interior surface having a radius of curvature approximating the radius of curvature of said tubular housing.
Claim 7
Dependent Claim
32 words
A circuit board socket as defined in claim 1 wherein said outer spring means sleeve portion has an open seam extending the length thereof to permit transverse flexure of said sleeve portion.
Claim 8
Dependent Claim
31 words
A circuit board socket as defined in claim 1 wherein each of said outer spring means finger portions has a terminating end located adjacent said flared portion of said tubular housing.
Claim 9
Dependent Claim
55 words
A circuit board socket as defined in claim 1 wherein said inner spring means comprises a central portion having a generally uniform exterior transverse dimension throughout substantially its entire length, said central portion exterior transverse dimension being arranged to closely approximate the interior transverse dimension of said tubular housing to provide a close fit therebetween.
Claim 10
Dependent Claim
28 words
A circuit board socket as defined in claim 1, said outer spring means sleeve portion further comprising means for locking said outer spring means to said tubular housing.
Claim 11
Dependent Claim
39 words
A circuit board socket as defined in claim 9 wherein said locking means comprises a lanced portion struck from said outer spring means sleeve portion and having a free end turned inwardly towards the interior of said sleeve portion.
