Abstract

Abstract A lamp assembly in which the lamp housing has a plurality of light bulb sockets and a slot for receiving an electric ribbon cable. The ribbon cable consists of a laminate of dielectric material having a plurality of electrical conductors embedded therein, the conductors having contact surfaces exposed through strategically placed windows in the dielectric material of the ribbon cable. Contact means retained within the housing extend from the exposed contact surface on a specific conductor to a specific light bulb socket.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 124 words
A lamp assembly comprising: a lamp housing having a plurality of light bulb receiving sockets, an electric ribbon cable, an elongated slot means in the housing receiving the ribbon cable, the ribbon cable consisting of a laminate of dielectric material having a plurality of parallel, longitudinally extending, mutually isolated, electrical conductors embedded therein, the ribbon cable having a plurality of windows in its surface to expose contact surfaces on the conductors, key slot means longitudinally locating the ribbon cable in the elongated slot means to align each window and thereby a related exposed contact surface with a specific light bulb socket, and contact means retained within the housing extending from the exposed contact surface on the specific conductor to the specific light bulb socket.
Claim 2
Dependent Claim 124 words
A lamp assembly comprising: a lamp housing having a plurality of light bulb receiving sockets, an electric ribbon cable, an elongated slot means in the housing receiving the ribbon cable, the ribbon cable consisting of a laminate of dielectric material having a plurality of parallel, longitudinally extending, mutually isolated, electrical conductors embedded therein, the ribbon cable having a plurality of windows in its surface to expose contact surfaces on the conductors, key slot means longitudinally locating the ribbon cable in the elongated slot means to align each window and thereby a related exposed contact surface with a specific light bulb socket, and contact means retained within the housing extending from the exposed contact surface on the specific conductor to the specific light bulb socket.
Claim 3
Dependent Claim 16 words
A lamp assembly according to claim 1, in which: the light bulb sockets are linearly aligned.
Claim 4
Dependent Claim 105 words
A lamp assembly according to claim 1, in which: the lamp housing is molded from an electrically nonconductive plastic, and the contact means comprises a plurality of U-shaped resilient metal contact elements, the housing having a plurality of spaced pairs of recesses with each pair having a common wall between its individual recesses, one of the recesses of each pair being in communication with the slot means receiving the ribbon cable and the other being in communication with a light bulb socket, and a contact element straddles the common wall between individual recesses to electrically bridge the gap between a conductor and a light bulb.
Claim 5
Dependent Claim 78 words
A lamp assembly according to claim 3, in which: each U-shaped resilient metal contact element has a first and second leg portion, the first leg portion extending into the one recess and having a plurality of fingers adapted to project through any adjacent window providing access to an exposed contact surface, and the second leg portion extending into the other recess and having a terminal portion engageable with the contact end of a bulb in the bulb socket.
Claim 6
Dependent Claim 206 words
A lamp assembly comprising: a lamp housing molded from an electrically nonconductive plastic and having a plurality of light bulb receiving sockets, an electric ribbon cable, an elongated slot means in the housing receiving the ribbon cable, the ribbon cable consisting of a laminate of di-electric material having a plurality of parallel, longitudinally extending, mutually isolated, electrical conductors embedded therein, the ribbon cable having a plurality of windows in its surface to expose contact surfaces on the conductors, each window being positioned to associate an exposed contact surface on a specific conductor with a specific light bulb socket, and contact means retained within the housing extending from the exposed contact surface on the specific conductor to the specific light bulb socket, the contact means comprising a plurality of U-shaped resilient metal contact elements, the housing having a plurality of spaced pairs of recesses with each pair having a common wall between its individual recesses, one of the recesses of each pair being in communication with the slot means receiving the ribbon cable and the other being in communication with a light bulb socket, and a contact element straddles the common wall between individual recesses to electrically bridge the gap between a conductor and a light bulb.
Claim 7
Dependent Claim 206 words
A lamp assembly comprising: a lamp housing molded from an electrically nonconductive plastic and having a plurality of light bulb receiving sockets, an electric ribbon cable, an elongated slot means in the housing receiving the ribbon cable, the ribbon cable consisting of a laminate of di-electric material having a plurality of parallel, longitudinally extending, mutually isolated, electrical conductors embedded therein, the ribbon cable having a plurality of windows in its surface to expose contact surfaces on the conductors, each window being positioned to associate an exposed contact surface on a specific conductor with a specific light bulb socket, and contact means retained within the housing extending from the exposed contact surface on the specific conductor to the specific light bulb socket, the contact means comprising a plurality of U-shaped resilient metal contact elements, the housing having a plurality of spaced pairs of recesses with each pair having a common wall between its individual recesses, one of the recesses of each pair being in communication with the slot means receiving the ribbon cable and the other being in communication with a light bulb socket, and a contact element straddles the common wall between individual recesses to electrically bridge the gap between a conductor and a light bulb.
Claim 8
Dependent Claim 78 words
A lamp assembly according to claim 5, in which: each U-shaped resilient metal contact element has a first and second leg portion, the first leg portion extending into the one recess and having a plurality of fingers adapted to project through any adjacent window providing access to an exposed contact surface, and the second leg portion extending into the other recess and having a terminal portion engageable with the contact end of a bulb in the bulb socket.
