Abstract
Abstract A unitary electrical receptacle or switch for installation after finishing of the surface in which it is to appear, which comprises internal electrical conductors for such a receptacle or switch enclosed by electrically insulating material which is formed into a housing portion and a cover plate portion, with openings in said housing portion for insertion of distribution cable to make the desired electrical contact with the internal conductors, openings in the cover plate portion for insertion of a plug into the receptacle or for protrusion of switching means from switches, and through-holes for connecting the unitary receptacle or switch to a structural member. Means may also be included for firmly connecting the distribution cable to such a receptacle or switch. The housing portion may be designed to straddle a structural member. The flanges formed by the cover plate portion overhanging the housing portion may be provided with shoulders adapted to the thickness of various surfacing materials.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
124 words
A pre-assembled electrical receptacle suitable for installation in light-frame building constructions, comprising: internal electrical conductors; a housing portion for said internal electrical conductors; a cover plate portion whose edges comprise flanges overhanging the sides of said housing portion; said housing and cover plate portions comprising electrically insulating material substantially surrounding said internal electrical conductors, said cover plate having openings therein to receive the prongs of electrical plugs for contacting said prongs with said internal conductors and said housing portion having means for contacting the wires of an electrical distribution cable to said internal conductors; and at least one through-hole extending from the front surface of the cover plate portion through said receptacle for attaching said receptacle to a structural member in light-frame building constructions.
Claim 2
Dependent Claim
124 words
A pre-assembled electrical receptacle suitable for installation in light-frame building constructions, comprising: internal electrical conductors; a housing portion for said internal electrical conductors; a cover plate portion whose edges comprise flanges overhanging the sides of said housing portion; said housing and cover plate portions comprising electrically insulating material substantially surrounding said internal electrical conductors, said cover plate having openings therein to receive the prongs of electrical plugs for contacting said prongs with said internal conductors and said housing portion having means for contacting the wires of an electrical distribution cable to said internal conductors; and at least one through-hole extending from the front surface of the cover plate portion through said receptacle for attaching said receptacle to a structural member in light-frame building constructions.
Claim 3
Dependent Claim
51 words
The receptacle of claim 1 additionally comprising a wedge-shaped key insert of electrically insulating material and a corresponding opening in the housing portion of said receptacle for said key which opening intersects another opening for receiving an end of said cable, for firmly attaching said receptacle to an electrical distribution cable.
Claim 4
Dependent Claim
25 words
The receptacle of claim 1 wherein said through-hole extends in a direction perpendicular to the front surface of the cover plate portion of the receptacle.
Claim 5
Dependent Claim
48 words
The receptacle of claim 1 wherein said through-hole extends in a direction oblique to the front surface of the cover plate portion, said oblique through-hole emerging through the housing portion of said receptacle for attachment of said receptacle to a surface adjacent the side of said housing portion.
Claim 6
Dependent Claim
28 words
The receptacle of claim 1 wherein the housing portion thereof has a rectilinear channel extending across its width for mounting on a structural member in light-frame building constructions.
Claim 7
Dependent Claim
81 words
The receptacle of claim 5, wherein said channel divides the back of said housing portion of said receptacle into two parts, said openings for receiving the end of an electrical distribution cable including holes for contacting the wires of said cable being in one of said parts, and a second opening for receiving the end of an electrical distribution cable, including second holes for contacting the wires of said cable to said internal conductors, being in the second of said parts.
Claim 8
Dependent Claim
20 words
The receptacle of claim 1 wherein said electrically insulating housing portion and cover plate portion are a single, integral structure.
Claim 9
Dependent Claim
130 words
A pre-assembled electrical switch apparatus suitable for installation in light-frame building constructions, comprising: internal electrical switching means; a housing portion for said internal electrical switching means; a cover plate portion whose edges comprise flanges overhanging the sides of said housing portion; said housing and cover plate portions comprising electrically insulating material substantially surrounding said internal electrical switching means, said cover plate having at least one opening therein for passage of a member for operating said switching means, and said housing portion having means for contacting the wires of an electrical distribution cable to said internal electrical switching means; and at least one through-hole extending from the front surface of the cover plate portion through said switch apparatus for attaching said switch apparatus to a structural member in light-frame building constructions.
Claim 10
Dependent Claim
130 words
A pre-assembled electrical switch apparatus suitable for installation in light-frame building constructions, comprising: internal electrical switching means; a housing portion for said internal electrical switching means; a cover plate portion whose edges comprise flanges overhanging the sides of said housing portion; said housing and cover plate portions comprising electrically insulating material substantially surrounding said internal electrical switching means, said cover plate having at least one opening therein for passage of a member for operating said switching means, and said housing portion having means for contacting the wires of an electrical distribution cable to said internal electrical switching means; and at least one through-hole extending from the front surface of the cover plate portion through said switch apparatus for attaching said switch apparatus to a structural member in light-frame building constructions.
Claim 11
Dependent Claim
81 words
An electrical terminal such as a receptacle or switch, comprising internal electrical conductors and a housing portion for said internal electrical conductors, said housing comprising electrically insulating material substantially surrounding said internal electrical conductors, and a wedge-shaped key including a locking tip portion and a corresponding opening for said key in the housing portion of said terminal, said opening intersecting another opening for receiving an end of an electrical distribution cable, for firmly attaching said terminal to an electrical distribution cable.
Claim 12
Dependent Claim
