Abstract
Abstract An electrical socket compatible with NEMA 5-15 and IEC 320 male connectors having conductor prong-accepting recesses, an IEC 320 shield-accepting peripheral recess and a pair of ground prong-accepting recesses, located to accept the ground prongs of both NEMA 5-15 and IEC 320 configurations. The ground prong-accepting recesses are provided with conductive inserts which are joined together to allow electrical continuity to be established with the ground prongs of either configuration.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
212 words
An electrical socket, comprising a socket body having front and rear faces, said socket body being formed of an insulating material; first and second parallel male prong-accepting means located on said front face and extending rearwardly into said socket body for establishing mechanical and electrical contact with male prongs mounted therein; a first ground prong-accepting means located between said first and second male prong-accepting means and offset vertically therefrom extending rearwardly into said socket body to accept the ground prong of an IEC 320 male plug and establish electrical contact threwith; a second ground prong-accepting means located between said first and second male prong-accepting means and above said first ground plug accepting means on said front face and extending rearwardly into said socket body to accept the ground prong of a NEMA 5-15 male plug and establish electrical contact therewith; a hexagonal IEC 320 shield-accepting recess located on said front face surrounding said first and second male prong-accepting means and first ground prong-accepting means extending rearwardly into said socket body; and means electrically joining said first and second ground prong-accepting and contacting means and extending rearwardly through said rear face to permit electrical continuity to be achieved with an inserted male plug having either an IEC 320 or NEMA 5-15 ground prong.
Claim 2
Dependent Claim
212 words
An electrical socket, comprising a socket body having front and rear faces, said socket body being formed of an insulating material; first and second parallel male prong-accepting means located on said front face and extending rearwardly into said socket body for establishing mechanical and electrical contact with male prongs mounted therein; a first ground prong-accepting means located between said first and second male prong-accepting means and offset vertically therefrom extending rearwardly into said socket body to accept the ground prong of an IEC 320 male plug and establish electrical contact threwith; a second ground prong-accepting means located between said first and second male prong-accepting means and above said first ground plug accepting means on said front face and extending rearwardly into said socket body to accept the ground prong of a NEMA 5-15 male plug and establish electrical contact therewith; a hexagonal IEC 320 shield-accepting recess located on said front face surrounding said first and second male prong-accepting means and first ground prong-accepting means extending rearwardly into said socket body; and means electrically joining said first and second ground prong-accepting and contacting means and extending rearwardly through said rear face to permit electrical continuity to be achieved with an inserted male plug having either an IEC 320 or NEMA 5-15 ground prong.
Claim 3
Dependent Claim
