Abstract

Abstract A lamp socket assembly for retaining a wedge base bulb and being configured to be insert mounted into the aperture of a rigid support panel so as to capture and make contact with exposed conductors on an intermediate flexible printed circuit layer. The socket assembly is further configured to be removable from the opposite side of the support panel from its original insertion.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 191 words
An insertable lamp bulb socket assembly for providing electrical interconnection between exposed conductor portions of a flexible printed circuit layer extending into an insertion aperture, formed between the surface of a rigid panel, and the electrical leads of a light emitting lamp mounted in said assembly, comprising: a cylindrical body portion extending along a central axis, having a first open end portion for receiving said lamp, a second tapered end portion and an intermediate portion between said first and second end portions for contacting the flexible printed circuit conductor; a locking means mounted on said body having a first resilient arm extending from said second end portion of said body towards said intermediate portion, wherein said arm has a first end portion normally biased to overlap the aperture in said rigid panel when said assembly is inserted therein; means on said intermediate portion and extending therefrom to overlap said aperture for limiting the axial insertion of said assembly into said aperture; and means within said intermediate portion for making electrical contact with exposed conductors of said flexible printed circuit layer along portions of said conductors that extend into the insertion aperture.
Claim 2
Dependent Claim 191 words
An insertable lamp bulb socket assembly for providing electrical interconnection between exposed conductor portions of a flexible printed circuit layer extending into an insertion aperture, formed between the surface of a rigid panel, and the electrical leads of a light emitting lamp mounted in said assembly, comprising: a cylindrical body portion extending along a central axis, having a first open end portion for receiving said lamp, a second tapered end portion and an intermediate portion between said first and second end portions for contacting the flexible printed circuit conductor; a locking means mounted on said body having a first resilient arm extending from said second end portion of said body towards said intermediate portion, wherein said arm has a first end portion normally biased to overlap the aperture in said rigid panel when said assembly is inserted therein; means on said intermediate portion and extending therefrom to overlap said aperture for limiting the axial insertion of said assembly into said aperture; and means within said intermediate portion for making electrical contact with exposed conductors of said flexible printed circuit layer along portions of said conductors that extend into the insertion aperture.
Claim 3
Dependent Claim 49 words
An assembly as in claim 1, wherein said resilient arm of said locking means is cantilever supported at said second end portion of said body and is compressible to force said end portion of said arm into a position which is not overlapping the aperture in said rigid panel.
Claim 4
Dependent Claim 57 words
An assembly as in claim 2, wherein said resilient arm of said locking means is mounted within said second tapered end portion of said body and is partially exposed along its length so that when its first end is compressed to its nonoverlapping position the arm is substantially flush with the surface of said tapered end portion.
Claim 5
Dependent Claim 27 words
An assembly as in claim 2, wherein said limiting means is opposing to and separated from said first end of said resilient arm by a predetermined distance.
Claim 6
Dependent Claim 49 words
An assembly as in claim 1, wherein said locking means includes a pair of commonly mounted resilient arms opposingly supported at said second tapered end portion of said body and said limiting means is opposing and separated from the first end of each resilient arm by a predetermined distance.
Claim 7
Dependent Claim 48 words
An assembly as in claim 5, wherein said resilient arms of said locking means are cantilever supported at said second end portion of said body and are compressible to force said end portions of said arms into positions which are not overlapping the aperture in said rigid panel.
Claim 8
Dependent Claim 38 words
An assembly as in claim 6, wherein said second tapered end portion of said body includes a tab means extending therefrom in a direction opposite to that of said first open end, for manual gripping of said assembly.
Claim 9
Dependent Claim 96 words
An assembly as in claim 7, wherein said insertion aperture contains a pair of diametrically opposed notch extensions on its periphery being open to a first surface of the rigid panel, extending through the panel for a predetermined distance and defining a stop surface that is parallel to said panel surfaces, and said limiting means contains surfaces which extend radially from said intermediate portion in diametrically opposite directions for abutting said stop surface in each notch extension when said assembly is inserted into said insertion aperture from the side of said first surface of said panel.
Claim 10
Dependent Claim 68 words
An assembly as in claim 8, wherein the thickness of the panel at the stop surfaces in of said notch extensions is less than the predetermined distance between said limiting means and said first end of each resilient arm and said first end of each resilient arm abuts the opposite side of the panel corresponding to said stop surface when said assembly is inserted into said insertion aperture.
Claim 11
Dependent Claim 62 words
An assembly as in claim 9, wherein each notch extension has a defined depth dimension measured from said first panel surface to said stop surface and a defined width dimension measured along a tangent to the aperture periphery and said limiting means also contains electrical contact elements that extend into said notch extensions when said assembly is inserted into said insertion aperture.
Claim 12
Dependent Claim 53 words
An assembly as in claim 10, wherein said insertion aperture contains a pair of diametrically opposed second notches that extend through, are open to both surfaces of said rigid panel and are of sufficient size to allow said limiting means to pass through when said assembly is rotationally oriented into axial alignment therewith.
Claim 13
Dependent Claim 62 words
An assembly as in claim 11, wherein said tab is oriented in a plane having a normal that is generally parallel to a radial extension of said stop surfaces and has width dimension that runs normal to the axial length of the assembly which is greater than the diameter of the aperture and less than the diametric distance between said second notches.
Claim 14
Dependent Claim 28 words
An assembly as in claim 7, wherein said resilient arms are integrally formed with each other and have outer edges that extend above and along said tapered end.
