Abstract
Abstract There is disclosed a safety electrical outlet such as a cube tap that is provided with sliding protective plates which overlie the prong-receiving slots of the outlet and are spring-biased to offset positions obstructing direct access to the receiving slots. The invention comprises an improvement over prior constructions in that a single resilient spring is employed to bias a pair of adjacent protective plates thereby greatly facilitating the assembly and reducing manufacturing costs. Additionally, the resilient spring is a spring of simple, bowed configuration which can be quickly and easily inserted in the supporting structure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
An electrical connector for receiving a prong type connector plug comprising: a body bearing, on at least one of its faces, juxtapositioned, prong-receptacle means to receive a plurality of said connector plugs; contactor strips carried internally of said body for electrical contact with prongs placed in said prong receptacles; a plurality of protective plates, each overlying a respective face area inclusive of a respective receptacle means and bearing prong-receiving aperture means; attachment means comprising dependent brackets projecting from the undersurface of said protective plates inwardly into face-central apertures in said body in sliding relationship therein between aligned and misaligned positions with respective prong receptacles; slot means in said body open to said face and extending beneath and between adjacent face areas; and resilient means for each adjacent pair of face areas comprising a spring having a central section received in said slot means and distal S-bowed sections, each resiliently biasing against the center of a respective bracket to urge a respective plate into its misaligned position.
Claim 2
Dependent Claim
166 words
An electrical connector for receiving a prong type connector plug comprising: a body bearing, on at least one of its faces, juxtapositioned, prong-receptacle means to receive a plurality of said connector plugs; contactor strips carried internally of said body for electrical contact with prongs placed in said prong receptacles; a plurality of protective plates, each overlying a respective face area inclusive of a respective receptacle means and bearing prong-receiving aperture means; attachment means comprising dependent brackets projecting from the undersurface of said protective plates inwardly into face-central apertures in said body in sliding relationship therein between aligned and misaligned positions with respective prong receptacles; slot means in said body open to said face and extending beneath and between adjacent face areas; and resilient means for each adjacent pair of face areas comprising a spring having a central section received in said slot means and distal S-bowed sections, each resiliently biasing against the center of a respective bracket to urge a respective plate into its misaligned position.
Claim 3
Dependent Claim
20 words
The electrical connector of claim 1 wherein each of said prong receptacle means comprises a pair of parallel, prong-receiving slots.
Claim 4
Dependent Claim
42 words
The electrical connector of claim 2 wherein said electrical connector is a cube tap comprising a molded body having, at one end thereof, an electrical cord of a plurality of electrical conductors in electrical contact with respective ones of said contactor strips.
Claim 5
Dependent Claim
16 words
The electrical connector of claim 3 wherein said face areas are recessions in said body face.
Claim 6
Dependent Claim
36 words
The electrical connector of claim 1 wherein said attachment means includes aperture means in said body face with said brackets carried on the undersurface of each said plate received in respective ones of said aperture means.
Claim 7
Dependent Claim
20 words
The electrical connector of claim 5 wherein said body has a central longitudinal cavity open to said body aperture means.
Claim 8
Dependent Claim
40 words
The electrical connector of claim 6 wherein said attachment means comprises a bracket plate downwardly dependent from each of said protective plate means and received in a respective body aperture and having distal, lateral projections received in said longitudinal cavity.
