Abstract

A mounting bar assembly for versatile positioning and orientation of indicator lights such as light emitting diodes (LED'"'"'s). The mounting bars are cut to a desired length to accommodate a desired number of LED'"'"'s and are cut to provide a plurality of slots at predetermined, spaced LED locations. The connector leads of the LED'"'"'s are inserted within the slots and adjusted in a direction generally perpendicular to the longitudinal direction of extent of the mounting bar so as to position each LED at a desired height with respect to a printed circuit board or other electrical circuit device to which the leads are connected. The connector leads are malleable, and after being secured to the mounting bar, are bent to any desired configuration so as to support each LED in a particular orientation as required.

Claims

1. An indicator light assembly comprising:

an elongated mounting bar having planar wall means extending longitudinally thereof;

a plurality of apertures extending through said wall means at predetermined locations along the length of said bar;

a plurality of indicator lights supported on said mounting bar at predetermined, spaced-apart locations thereon as defined by said apertures, each of said indicator lights having a plurality of electrical connector leads attached thereto and extending therefrom in the same direction whereby each indicator light is freely suspended along one end of a pair of said leads, and said apertures being arranged in laterally adjacent sets, with the rest of leads for each indicator light being contained within a set of said apertures to extend in a direction generally perpendicular to the longitudinal direction of extent of said wall means at a desired position of adjustment along said lead direction, with each of said indicator light being freely supported at a desired height a predetermined displacement distance from said planar wall means only along said one end of a pair of said leads;

means securing each of said connector leads within said apertures and affixing said leads to said mounting bar only along the opposite ends thereof from said one end, with a predetermined lead portion opposite said one end thereof being exposed for connection to an electrical contact means; and

each of said connector leads being made of conductive metal which is malleable and bendable, yet rigid enough to be self-supporting and to hold any position to which it is bent, whereby the lengths of said leads projecting outwardly from said mounting bar between said mounting bar and said indicator lights may be bent to any desired angle or configuration so as to orient each of said indicator lights in a predetermined, desired position.

2. An indicator light assembly as defined in claim 1 wherein:

said wall means has a free edge along the planar direction of extent thereof, and said apertures are in the form of slots extending to and through said free edge to provide exposed slot access openings along said free edge, whereby said connector leads may be inserted into said slots through said access openings in a direction coextensive with said planar direction of extent of said planar wall means.

3. An indicator light assembly as defined in claim 1 wherein:

each of said indicator lights is an LED.

4. An indicator light assembly as defined in claim 1 wherein:

said means affixing said connector leads to said mounting bar comprises glue.

5. An indicator light assembly as defined in claim 4 wherein:

said glue is an epoxy resin.

6. An indicator light assembly as defined in claim 1 wherein:

said mounting bar is of generally C-shaped configuration when oriented horizontally with said connector leads extending generally vertically through said apertures and said planar wall means comprises top and bottom walls projecting from a back wall of said mounting bar, and said top and bottom walls being vertically spaced apart in said horizontal orientation of said bar to define an open channel therebetween, and said apertures comprising vertically aligned pairs of openings extending through said top and bottom walls, with each lead passing through an aligned, vertically-spaced pair off said openings as well as through said channel and being contained therein.

7. An indicator light assembly as defined in claim 6 wherein said means affixing said leads to said mounting bar comprises glue applied within said channel around said leads.

8. An indicator light assembly as defined in claim 1 wherein

the connector leads of at least one indicator light affixed to said mounting bar depend beyond said mounting bar on the side thereof opposite said indicator light and are bent to a generally horizontal configuration in a common plane, whereby said leads may be positioned to lie along the surface of a printed circuit board for surface mount attachment thereto.

9. An indicator light assembly as defined in claim 8 wherein:

said mounting bar is of generally C-shaped configuration and said planar wall means comprises top and bottom walls projecting from a back wall of said mounting bar in parallel spaced-apart relation to define an open channel therebetween, said channel being open at least at one end of said mounting bar; and

at least one support member removably positioned on and embracing said one end of said mounting bar to stabilize said mounting bar during connection of said connector leads to electrical contact means such as a printed circuit board, said support member having a portion thereof restrainably

10. An indicator light assembly as defined in claim 9 wherein:

said support member is of inverted U-shaped and comprises a pair of legs connected at their upper ends by a cross member, said support member being slidably attached to said one end of said mounting bar with said cross member overlying only an end segment of said top wall adjacent said one end of said mounting bar and said legs depending downwardly below said bottom wall of said mounting bar on opposite sides thereof in position to rest on the surface of the electrical device to which the leads of said indicator lights are to be connected.

11. An indicator light assembly as defined in claim 10 wherein:

said portion of said support member restrainably engaging said mounting bar comprises a shoulder projecting from the inside surface of one of said legs and engaging under the inside, lower surface of said top wall.

12. An indicator light assembly as defined in claim 7 wherein:

said leads are substantially the same width as said openings, with enough clearance being provided in the width of said openings for the insertion of said leads therein.

13. An indicator light assembly as defined in claim 6 wherein:

said C-shaped mounting bar is open along the side thereof opposite said back wall, and each of said top and bottom walls have a free edge along said open side of said C-shaped mounting bar; and

said apertures comprise slots extending through said top and bottom walls and to said free edge thereof to provide exposed acesses openings along said free edges of said top and bottom walls, whereby said connector leads may be inserted into said slots through said access openings to extend in said direction generally perpendicular to said top and bottom walls.
