Filed:

Jul 17, 2009

Appl. No.:

12/458646

Inventors:

Dennis A. Oddsen - Northport NY, US
Jian H. Li - New York NY, US

Assignee:

Hubbell Incorporated - Shelton CT

International Classification:

H01R 4/66

US Classification:

439106

Abstract:

An electrical receptacle with a body sized to fit in a NEMA-standard single wall box has a substantially rectangular face with phase blade openings, neutral blade openings and ground prong openings associated with respective first, second and third outlets, each outlet having a centerline passing through its ground prong opening parallel to its phase and neutral blade openings. The centerline of the first outlet is oblique to the edges of the face and oblique to the centerline of at least one other outlet. The centerlines of all of the outlets may be mutually nonparallel, and they may be mutually oblique. The centerline of the second outlet may be parallel to an edge of the face; and if so, the centerline of the third outlet may be either perpendicular to or parallel to the centerline of the second outlet. In a preferred arrangement, the centerlines are mutually nonparallel, and the ground prong openings of two of the outlets are located at corners of the face that share a common longer edge. All of the arrangements simultaneously accommodate plugs, chargers and transformers of many known sizes and types.

International Classification:

H01R 13/453

Abstract:

A tamper resistant receptacle having a propeller shutter assembly comprising a propeller shutter comprising a central hub with an annual opening, a pair of radially extending arms, and a wing block disposed on the end of each arm. The shutter assembly also includes an anchor for attaching the propeller to the receptacle body and a spring member to bias the propeller in the “closed” position. The wing blocks are sized to block a respect one of the hot and neutral openings of a standard 15-amp electrical receptacle. The wing blocks each include a ramp or inclined cam surface. These surfaces are juxtaposed such that when a plug blade hit one surface and cams past it to cause rotation of the propeller, the opposite plug blade cams down and past the other surface to cause rotation of the propeller in the same direction. This configuration causes the propeller to translate vertical force from the plug blades into rotational force in a direction and of sufficient force to overcome the spring bias of the spring and rotate the propeller wing block out of the way of the electrical contacts such that the blades can “plug in” to the device's electrical contacts.
