Abstract

Abstract A holder made of resilient plastic material is disclosed for mounting a light-emitting diode having a rectangular-shaped base into a rectangular-shaped aperture of a panel member. The holder has a rectangular-shaped hollow body of a cross section slightly smaller than the rectangular-shaped aperture in the panel and is molded with a rectangular-shaped lengthwise throughbore for receiving a rectangular-shaped light-emitting diode. The rectangular-shaped body is molded into a first pair of opposing sidewalls and a second pair of opposing sidewalls. A pair of spaced lengthwise elongate slots are formed in the second pair to define a flexible central web portion in each sidewall of the second pair. The LED holder is retained in the rectangular-shaped aperture between an outwardly extending flange portion formed around the periphery of the upper end of the body, and a pair of resilient arm means formed on the outside surface of the first pair of opposite sidewalls, which provide a snapping engagement with the lower surface of the apertured panel. Crush rib means are formed on the outside surface of the web portions in a lengthwise direction to provide a wedging action between the LED holder and the apertured panel when the LED is inserted into the LED holder. A pair of shoulder latching means integrally formed on the inside surface of the web portions provide the means for engaging and holding the bottom edge surface of a rectangular-shaped base of a light-emitting diode.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 229 words
A holder of resilient plastic material for mounting a light-emitting diode in an apertured panel having a rectangular aperture defined by four sidewalls formed through the thickness dimension of said panel, comprising a regular-shaped hollow body having a central opening extending along the axis of said body, two pairs of axially extending, spaced elongate slots formed through the sidewall of said hollow body to define two axially extending flexible web portions therebetween, said web portions being disposed diametrically opposite to each other relative to the axis of said regular-shaped body, an outwardly extending flange portion integrally connected around the periphery of the upper end of said body, a pair of resilient arm means formed on the outside surface of said body and disposed diametrically opposite relative to said axis, each of said arm means located at a distance below said flange portion for snapping into engagement with the lower surface of said apertured panel, resilient rib means integrally formed on the outside surface of each said web portions and extending axially adjacent to said flange portion for wedging said web portions into tight interfitting engagement with two opposing sidewalls of said four sidewalls of said rectangular aperture, and a shoulder latching means integrally formed on the inside surface of each of said web portions for engaging and holding the bottom edge surface of the base of a light-emitting diode.
Claim 2
Dependent Claim 229 words
A holder of resilient plastic material for mounting a light-emitting diode in an apertured panel having a rectangular aperture defined by four sidewalls formed through the thickness dimension of said panel, comprising a regular-shaped hollow body having a central opening extending along the axis of said body, two pairs of axially extending, spaced elongate slots formed through the sidewall of said hollow body to define two axially extending flexible web portions therebetween, said web portions being disposed diametrically opposite to each other relative to the axis of said regular-shaped body, an outwardly extending flange portion integrally connected around the periphery of the upper end of said body, a pair of resilient arm means formed on the outside surface of said body and disposed diametrically opposite relative to said axis, each of said arm means located at a distance below said flange portion for snapping into engagement with the lower surface of said apertured panel, resilient rib means integrally formed on the outside surface of each said web portions and extending axially adjacent to said flange portion for wedging said web portions into tight interfitting engagement with two opposing sidewalls of said four sidewalls of said rectangular aperture, and a shoulder latching means integrally formed on the inside surface of each of said web portions for engaging and holding the bottom edge surface of the base of a light-emitting diode.
Claim 3
Dependent Claim 56 words
A holder as defined in claim 1, wherein said shoulder latching means comprises an integrally formed abutment on said inside surface of each of said web portions, each of said abutments having a radially extending latching sholder with respect to said axis, each of said latching shoulders being in radial alignment with the other latching shoulder.
Claim 4
Dependent Claim 42 words
A holder as defined in claim 1, wherein each of said resilient rib means comprises a resilient elongate wedge integrally formed on said outside surface of one of said web portions and having a gradually decreasing thickness away from said flange portion.
Claim 5
Dependent Claim 42 words
A holder as defined in claim 1, further comprising latching arm means extending from the bottom of said body for holding a female receptacle member adapted to electrically connect the electrical leads of a light-emitting diode to a pair of electrical contact.
