Abstract
Abstract An incandescent lampholder, usually of the miniature or ''''candelabra'''' type and designed for use by original equipment manufacturers, is former at its base end with a pair of wiring openings or wireways that are defined by a triangular or wedgeshaped divider, the walls of which converge toward said end. Each wireway opens upon both the bottom and side of the lampholder, so that the wires can exit from the lampholder in a direction normal to the longitudinal axis thereof, parallel or oblique thereto, or in any combination of these directions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A lampholder for incandescent lamps comprising: a. an electrically insulative body having a lamp socket at one end; b. spaced contacts in said body for making electrical contact with corresponding contacts of an incandescent lamp mounted in the socket, said body having openings at its other end for wire leads and being formed with a wedge-shaped divider between said openings; and c. wire leads connected to the respective lampholder contacts and extending through said openings, each of the openings extending continuously from the divider across the second-named end of the body and part way up the adjacent side of the body, the portions of the openings extending within the sides of the body being of a size to accommodate the entire thickness of its associated wire lead, said body being formed with wireways extending from the respective lampholder contacts to the openings, the body including strain relief projections within the wireways gripping the leads at locations in advance of the portions of the leads extending within the openings.
Claim 2
Dependent Claim
168 words
A lampholder for incandescent lamps comprising: a. an electrically insulative body having a lamp socket at one end; b. spaced contacts in said body for making electrical contact with corresponding contacts of an incandescent lamp mounted in the socket, said body having openings at its other end for wire leads and being formed with a wedge-shaped divider between said openings; and c. wire leads connected to the respective lampholder contacts and extending through said openings, each of the openings extending continuously from the divider across the second-named end of the body and part way up the adjacent side of the body, the portions of the openings extending within the sides of the body being of a size to accommodate the entire thickness of its associated wire lead, said body being formed with wireways extending from the respective lampholder contacts to the openings, the body including strain relief projections within the wireways gripping the leads at locations in advance of the portions of the leads extending within the openings.
Claim 3
Dependent Claim
163 words
A lampholder for an incandescent lamp, comprising; a. an electrically insulative body formed as a pair of generally semicylindrical halves joined in confronting relation, each half having a semicylindrical recess at one end formed with thread segments so as to define, in the assembled body, a threaded socket for an incandescent lamp; b. a center contact and a shell contact for making electrical contact with said lamp, each of said contacts being formed of a strip metal and being clamped between said halves; c. wire leads secured to the respective contacts, said body having at its other end a divider disposed between a pair of wire-receiving openings formed in the body at said other end thereof, said divider having walls that converge toward said other end of the body and define sloped inner sidewalls of said openings, each of the openings extending continuously from the divider across said other end of the body and part way up the adjacent side of the body.
Claim 4
Dependent Claim
163 words
A lampholder for an incandescent lamp, comprising; a. an electrically insulative body formed as a pair of generally semicylindrical halves joined in confronting relation, each half having a semicylindrical recess at one end formed with thread segments so as to define, in the assembled body, a threaded socket for an incandescent lamp; b. a center contact and a shell contact for making electrical contact with said lamp, each of said contacts being formed of a strip metal and being clamped between said halves; c. wire leads secured to the respective contacts, said body having at its other end a divider disposed between a pair of wire-receiving openings formed in the body at said other end thereof, said divider having walls that converge toward said other end of the body and define sloped inner sidewalls of said openings, each of the openings extending continuously from the divider across said other end of the body and part way up the adjacent side of the body.
Claim 5
Dependent Claim
27 words
A lampholder as in claim 2 wherein one of said halves has, adjacent said recess thereof, a boss mating with a complementary indentation of the other half.
Claim 6
Dependent Claim
26 words
A lampholder as in claim 3 wherein said contacts extend along opposite sides of the boss, said halves meeting along a line longitudinally bisecting the contacts.
