Abstract

Abstract A multiple outlet receptacle, such as one having four outlets in respective quadrants, is provided with a surge suppression circuit including a metal oxide varistor edgewise between the front and back of the device, other electronic elements, including dual status indicators, connected with an outer ring like contact plate and secured within portions of the insulating housings. Features for compactness and ease of assembly are provided. A pilot light indicator may alternatively be provided in receptacles without a surge suppressor utilizing some of the same components and assembly features.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 198 words
A multiple outlet receptacle with surge suppression comprising: a molded insulation housing for permanent installation, said housing having a front face with plug blade receiving apertures for each of more than two outlets arranged in respective areas of said front face, said housing having a back face with wire terminals, said back face further provided with a bowed-out portion; a plurality of contact elements disposed in said housing, said contact elements including a first group of contact elements attached to a first conductive plate configured as an apertured ring and a second group of contact elements attached to a second conductive plate that is coplanar with said first conductive plate and that is disposed within said aperture of said first conductive plate, said second conductive plate having at least one opening; and a surge suppression circuit including at least one surge suppressor connected to said contact elements and located within said housing, said surge suppressor including a substantially disk shaped metal oxide varistor physically arranged substantially on edge between said front and back faces of said housing; said varistor extending through said opening in said second conductive plate and extending into said bowed-out portion of said back face.
Claim 2
Dependent Claim 198 words
A multiple outlet receptacle with surge suppression comprising: a molded insulation housing for permanent installation, said housing having a front face with plug blade receiving apertures for each of more than two outlets arranged in respective areas of said front face, said housing having a back face with wire terminals, said back face further provided with a bowed-out portion; a plurality of contact elements disposed in said housing, said contact elements including a first group of contact elements attached to a first conductive plate configured as an apertured ring and a second group of contact elements attached to a second conductive plate that is coplanar with said first conductive plate and that is disposed within said aperture of said first conductive plate, said second conductive plate having at least one opening; and a surge suppression circuit including at least one surge suppressor connected to said contact elements and located within said housing, said surge suppressor including a substantially disk shaped metal oxide varistor physically arranged substantially on edge between said front and back faces of said housing; said varistor extending through said opening in said second conductive plate and extending into said bowed-out portion of said back face.
Claim 3
Dependent Claim 24 words
A receptacle in accordance with claim 1 wherein: said surge suppression circuit further includes at least one condition indicator visible on said front face.
Claim 4
Dependent Claim 56 words
A receptacle in accordance with claim 2 wherein: said at least one condition indicator comprises a first light emitting device which when lit indicated power to the receptacle is on and surge suppression is lost and a second light emitting device which when lit indicates power to the receptacle is on and surge suppression is present.
Claim 5
Dependent Claim 26 words
A receptacle in accordance with claim 3 wherein: said first and second light emitting devices are located at substantially opposite extremes of said housing front face.
Claim 6
Dependent Claim 23 words
A receptacle in accordance with claim 4 wherein: said surge suppression circuit includes a fuse and resistors located proximate said first conductive plate.
Claim 7
Dependent Claim 56 words
A receptacle in accordance with claim 5 wherein: a receptacle further includes a ring-shaped ground plate exterior of said back face substantially opposite said second conductive plate in the housing interior; and said surge suppressor has a first connection directly connected to said ground plate and a second connection directly connected to said second conductive plate.
Claim 8
Dependent Claim 87 words
A receptacle in accordance with claim 6 wherein: said surge suppressor includes a pair of disk shaped metal oxide varistor elements in close parallel relation within an insulating covering from which an outer lead extends respectively from one outer surface of each of said pair of elements and a center tap lead from between said pair of elements, said outer lead from one varistor element being connected to said ground plate and said outer lead from the other varistor element being connected to said second conductive plate.
Claim 9
Dependent Claim 51 words
A receptacle in accordance with claim 7 and further comprising: a connection from said center tap lead to a first side of said fuse and a connection from a second side of said fuse to said first conductive plate to provide surge suppression between each pair of a wire distribution system.
Claim 10
Dependent Claim 43 words
A receptacle in accordance with claim 6 wherein said housing includes a rib extending outwardly from said back face a distance substantially the same as the distance said bowed-out portion extends from said back face, said ground plate being positioned by said rib.
Claim 11
Dependent Claim 196 words
An outlet receptacle having at least four outlets accessible by plug blade apertures with surge suppression means comprising: a molded insulation housing for permanent installation and having a plurality of contact elements therein, said housing having a front face with plug blade receiving apertures for said outlets arranged in respective areas of said front face, said housing having a back face with wire terminals; said contact elements including a first group of contact elements attached to a first conductive plate configured as an apertured ring and a second group of contact elements attached to a second conductive plate that is disposed within said aperture of said first conductive plate and coplanar therewith, said second conductive plate having at least one opening therein; and at least one viewable indicator associated with surge suppression components, said indicator being viewable through said front face of said housing, said indicator and surge suppression components being positioned within the outer periphery of said first plate, and at least one surge suppression component extending through said opening in said second conductive plate from said front face to said back face, said indicator indicating a status of said surge suppression circuit when energized.
Claim 12
Dependent Claim 196 words
An outlet receptacle having at least four outlets accessible by plug blade apertures with surge suppression means comprising: a molded insulation housing for permanent installation and having a plurality of contact elements therein, said housing having a front face with plug blade receiving apertures for said outlets arranged in respective areas of said front face, said housing having a back face with wire terminals; said contact elements including a first group of contact elements attached to a first conductive plate configured as an apertured ring and a second group of contact elements attached to a second conductive plate that is disposed within said aperture of said first conductive plate and coplanar therewith, said second conductive plate having at least one opening therein; and at least one viewable indicator associated with surge suppression components, said indicator being viewable through said front face of said housing, said indicator and surge suppression components being positioned within the outer periphery of said first plate, and at least one surge suppression component extending through said opening in said second conductive plate from said front face to said back face, said indicator indicating a status of said surge suppression circuit when energized.
Claim 13
Dependent Claim 16 words
A receptacle in accordance with claim 10 wherein said viewable indicator includes two spaced-apart indicator lights.
Claim 14
Dependent Claim 42 words
A receptacle in accordance with claim 10 and further comprising a bowed-out portion in said back face, at least one of said surge suppression components extending from said front face through said opening in said second conductive plate into said bowed-out portion.
