US4595859A — Halogen incandescent lamp and socket combination,…

Claim 1

Independent Claim 297 words

An integrally formed, unitary lamp socket in combination with a halogen incandescent lamp (1) wherein the halogen incandescent lamp has a base (4) formed as a glass press which includes, at least in part, a flat plate-like portion; at least one extending projection (5) formed on, and extending transversely to the longitudinal axis (A) of, the base press (4) to define a locating, positioning and holding projection; and electrical terminal leads (3) extending from the base (4); and, wherein the socket includes an essentially cylindrical element (2) formed with a recess (6) therein shaped to receive, through an opening defining one end of said recess, the base (4) of the lamp, and the terminal leads (3) projecting therefrom; and further comprising, a pair of oppositely positioned, resiliently deflectable separating walls (8) located in the recess (6) of the socket, defining essentially rectangular chords through said cylindrical element (2), and secured thereto, and resiliently engaging opposite flat sides of the plate-like portion of the base (4) of the lamp; a supporting flange (13) formed with and circumferentially projecting from said cylindrical element (2) and adapted for direct mounting of said lamp-socket combination in any desired plate-like structure (P); and an engagement edge (9), formed on at least one of said separating walls (8), located and shaped with a surface extending perpendicular to the longitudinal axis (A) of said lamp press (4) for positive engagement over the holding projection (5) on the base (4) of the lamp, for positioning the lamp in the socket, holding the lamp in position, and preventing unintended axial movement of the lamp from the socket after insertion of the lamp in the socket, and for resilient snap-in of the engagement edge (9) over the holding projection (5) on the base (4) of the lamp.

Claim 2

Dependent Claim 297 words

An integrally formed, unitary lamp socket in combination with a halogen incandescent lamp (1) wherein the halogen incandescent lamp has a base (4) formed as a glass press which includes, at least in part, a flat plate-like portion; at least one extending projection (5) formed on, and extending transversely to the longitudinal axis (A) of, the base press (4) to define a locating, positioning and holding projection; and electrical terminal leads (3) extending from the base (4); and, wherein the socket includes an essentially cylindrical element (2) formed with a recess (6) therein shaped to receive, through an opening defining one end of said recess, the base (4) of the lamp, and the terminal leads (3) projecting therefrom; and further comprising, a pair of oppositely positioned, resiliently deflectable separating walls (8) located in the recess (6) of the socket, defining essentially rectangular chords through said cylindrical element (2), and secured thereto, and resiliently engaging opposite flat sides of the plate-like portion of the base (4) of the lamp; a supporting flange (13) formed with and circumferentially projecting from said cylindrical element (2) and adapted for direct mounting of said lamp-socket combination in any desired plate-like structure (P); and an engagement edge (9), formed on at least one of said separating walls (8), located and shaped with a surface extending perpendicular to the longitudinal axis (A) of said lamp press (4) for positive engagement over the holding projection (5) on the base (4) of the lamp, for positioning the lamp in the socket, holding the lamp in position, and preventing unintended axial movement of the lamp from the socket after insertion of the lamp in the socket, and for resilient snap-in of the engagement edge (9) over the holding projection (5) on the base (4) of the lamp.

Claim 3

Dependent Claim 36 words

Lamp according to claim 1, wherein the separating walls (8) are integral with the socket and comprise inwardly extending, outwardly resiliently deflectable wall portions connected at least at two of their edge portions with the socket.

Claim 4

Dependent Claim 32 words

Lamp according to claim 2, wherein the resiliently deflectable walls (8) are connected with the remainder of the socket along edges extending parallel to a longitudinal axis (A) through the lamp (1).

Claim 5

Dependent Claim 28 words

Lamp according to claim 1, werein the engagement edges (9) comprise inwardly projecting ridges extending transversely to an axis (A) passing through the lamp (1) and the socket.

Claim 6

Dependent Claim 61 words

Lamp according to claim 1, wherein the resiliently deflectable separating walls (8) are integral with the socket (2) and connected thereto at three of the edges of the separating walls (8) located remote from the opening of the recess (6); and the engagement edges (9) comprise inwardly extending ribs located at a position close to the opening of the recess (6).

Claim 7

Dependent Claim 17 words

Lamp according to claim 1, wherein the socket and the separating wall comprise an integral plastic element.

Claim 8

Dependent Claim 74 words

Lamp according to claim 1, wherein the recess (6) is essentially cylindrical; the separating walls extend along a chord of the recess to engage the flat, plate-like glass press (4) of the lamp; and further including terminal strips (7) fitted into the recess (6) and positioned adjacent the lateral edge portions of the separating walls (8) and a space defined between the separating walls in which the plate-like glass press (4) can be received.

Claim 9

Dependent Claim 33 words

Lamp according to claim 7, further including inwardly extending grooves (10) formed in the socket (2) adjacent the edges of the terminal strip (7) for receiving the edge portions of the terminal strip.

Claim 10

Dependent Claim 46 words

Lamp according to claim 7, further including a radial recess formed in the socket (2) and extending in the space to receive the glass press (4) of the lamp; and wherein the terminal strips are formed with outwardly projecting tongues (11) engaging in said radial recess.

Claim 11

Dependent Claim 16 words

Lamp according to claim 1, wherein the recess (6) within the socket (2) is a through-bore.

Claim 12

Dependent Claim 53 words

Lamp according to claim 9, wherein the recess (6) within the socket (2) is a through-bore; and wherein the terminal strips (7) are mechanically and electrically connected to the electrical terminal leads (3) extending from the base (4) of the lamp in the region of the through-bore (6) remote from the lamp (1).

Claim 13

Dependent Claim 41 words

Lamp according to claim 11, wherein the socket (2) is formed with an outer wall (2') which is axially relieved in the region of the bonding connection between the terminal strips (7) and the electrical terminal leads (3) of the lamp.
