Abstract
Abstract A unitary retainer socket device for providing positive interconnection between a male pin conductor of an electrical instrument and exposed conductor runs of a flexible printed circuit material is formed to be inserted into and extend from both ends of an open ended aperture in a rigid panel that supports the flexible printed circuit. A base element is centrally formed in the socket and has spring biasing tabs extending therefrom to prevent insertion of the base element into the support panel aperture and to provide holding forces to the flexible circuit material against the surface of the support panel. Pairs of legs extend from the base element at a distance that exceeds the depth of the support panel aperture so as to extend therethrough. Retrorse tabs are defined at each leg pair to lockingly retain the socket in the aperture by engaging the end of the aperture opposite to the insertive end. Electrical contacts of the socket are compressed against the side walls of the support panel aperture by insertion of the male pin conductor in the socket and provide positive electrical contact to the exposed conductor runs of the printed circuit material that extends into the support panel aperture along the side walls.

Total Claims: 8
Claim 1
Independent Claim
207 words
A unitary retainer socket for providing a positive mechanical and electrical interconnection between a male pin conductor and a flexible printed circuiPt having exposed conductors while inserted in a walled aperture of a rigid support panel of a predetermined depth, comprising: a generally planar base portion; two pair of opposing legs extending in a generally normal direction from said base portion wherein the legs of each pair are separated by a defined contact space; a pair of spring tabs extending from said base to provide resilient biasing of said socket against said flexible printed circuit when inserted in said panel aperture; a retrorse locking tab extending from between each leg pair towards a corresponding spring tab; an inner contact guide extending from each leg pair in a direction back towards said base portion forming continuous opposed surfaces separated by a distance that is less than the thickness of said male pin conductor for receiving and contacting said male pin conductor; and an electrical contact extending outwardly from each of said inner contact guides and being compressible by the insertion of said male pin conductor between said inner contact guides to positively compress the exposed conductors of said flexible printed circuit against opposing walls of said panel aperture.
Claim 2
Dependent Claim
207 words
A unitary retainer socket for providing a positive mechanical and electrical interconnection between a male pin conductor and a flexible printed circuiPt having exposed conductors while inserted in a walled aperture of a rigid support panel of a predetermined depth, comprising: a generally planar base portion; two pair of opposing legs extending in a generally normal direction from said base portion wherein the legs of each pair are separated by a defined contact space; a pair of spring tabs extending from said base to provide resilient biasing of said socket against said flexible printed circuit when inserted in said panel aperture; a retrorse locking tab extending from between each leg pair towards a corresponding spring tab; an inner contact guide extending from each leg pair in a direction back towards said base portion forming continuous opposed surfaces separated by a distance that is less than the thickness of said male pin conductor for receiving and contacting said male pin conductor; and an electrical contact extending outwardly from each of said inner contact guides and being compressible by the insertion of said male pin conductor between said inner contact guides to positively compress the exposed conductors of said flexible printed circuit against opposing walls of said panel aperture.
Claim 3
Dependent Claim
33 words
A retainer socket as in claim 1, wherein each of said spring tabs extend from between a pair of legs and is slightly inclined from said base in a direction towards said legs.
Claim 4
Dependent Claim
43 words
A retainer socket as in claim 2, wherein each pair of opposing legs are separated from the other pair at their extreme ends remote from said base portion by a distance that is greater than the distance of separation at the base portion.
Claim 5
Dependent Claim
47 words
A retainer socket, as in claim 3, wherein said electrical contacts are oppositely located with respect to each other to be compressively forced through said defined contact space and into contact with the exposed conductor of said flexible printed circuit against the wall of said panel aperture.
Claim 6
Dependent Claim
66 words
A retainer socket, as in claim 4, for insertion into a rectangular aperture in said panel having a pair of stop elements protruding from opposing side walls, said socket further including a pair of stop tabs extending coplanar from said base portion in directions normal to the extension of said spring tabs to abut said stop elements when said socket is inserted into said rectangular aperture.
Claim 7
Dependent Claim
74 words
A retainer socket, as in claim 4, for insertion into a rectangular aperture in said panel having a pair of stop elements located along the shortest edges of the rectangular aperture and protruding outward therefrom and said socket further includes a pair of stop tabs extending coplanar from said base portion in directions normal to the extension spring tabs to abut the outward ends of said stop elements when inserted into said rectangular aperture.
Claim 8
Dependent Claim
54 words
A retainer socket as in claim 4, wherein the extreme ends of the leg pairs and the base portion are separated by a distance that is greater than the depth of the panel aperture so that said base portion and said retrorse tabs are outside the panel aperture when the socket is inserted therein.
