Abstract
Abstract An electrical socket has a body with a pair of spaced-apart channels for receiving the prongs of a male electrical plug. A pair of electrical contacts are mounted in said body respectively adjacent to said channels and in communication therewith. A pair of legs are pivotally mounted on the body and are movable between locking and unlocking positions. Each leg carries a finger which enters the aperture of the prong on the associated electrical plug when the legs are in the locking position thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
159 words
An electrical socket for interconnection with a male electrical plug having two spaced-apart prongs, respectively with apertures near the ends thereof, said socket comprising a body having a pair of spaced-apart channels therein respectively to receive the prongs of the male electrical plug, said body further having therein a pair of outwardly facing, oppositely directed recesses, a pair of electrical contacts in said body and respectively adjacent to said channels and in communication therewith, a pair of legs pivotally mounted on said body and movable between a locking position respectively in said recesses and respectively alongside said channels and an unlocking position respectively out of said recesses and respectively away from said channels, and a pair of fingers respectively carried by said legs and located thereon respectively to enter the apertures of the prongs when the legs are in the locking positions thereof and to be withdrawn from the apertures when the legs are in the unlocking positions thereof.
Claim 2
Dependent Claim
159 words
An electrical socket for interconnection with a male electrical plug having two spaced-apart prongs, respectively with apertures near the ends thereof, said socket comprising a body having a pair of spaced-apart channels therein respectively to receive the prongs of the male electrical plug, said body further having therein a pair of outwardly facing, oppositely directed recesses, a pair of electrical contacts in said body and respectively adjacent to said channels and in communication therewith, a pair of legs pivotally mounted on said body and movable between a locking position respectively in said recesses and respectively alongside said channels and an unlocking position respectively out of said recesses and respectively away from said channels, and a pair of fingers respectively carried by said legs and located thereon respectively to enter the apertures of the prongs when the legs are in the locking positions thereof and to be withdrawn from the apertures when the legs are in the unlocking positions thereof.
Claim 3
Dependent Claim
16 words
The electrical socket set forth in claim 1, wherein each recess is U-shaped in cross section.
Claim 4
Dependent Claim
39 words
The electrical socket set forth in claim 1, wherein said body has a pair of separating walls respectively between said channels and said recesses, each of said walls having an opening therein through which the associated finger is movable.
Claim 5
Dependent Claim
29 words
The electrical socket set forth in claim 1, wherein said body has a pair of stop surfaces thereon to limit movement of said legs respectively away from said body.
Claim 6
Dependent Claim
14 words
The electrical socket of claim 1, wherein said legs are integral with said body.
Claim 7
Dependent Claim
94 words
The electrical socket set forth in claim 1, wherein each of said legs has hingedly connected first and second sections, one end of said first section being pivotally mounted to said body, said body having fulcrum means opposite a region on said second section, an associated finger being on said second section between said region and the free end thereof, whereby pressure of the thumb and forefinger respectively in the regions of said hinges respectively simultaneously pivots said second sections of said legs about said fulcrum means to withdraw said fingers from the apertures.
Claim 8
Dependent Claim
83 words
The electrical socket set forth in claim 1, wherein each of said legs is rigid and is pivotally mounted to said body at a point between the ends thereof, thereby defining first and second sections of said leg on each side of said point, said finger being located on said first section, said second sections respectively of said legs being simultaneously gripable respectively by the thumb and forefinger to be moved toward each other to place said legs in the unlocking positions thereof.
Claim 9
Dependent Claim
33 words
The electrical socket set forth in claim 1, wherein said legs are held in said body in the locking positions thereof by means of substantial frictional engagement between said legs and said body.
Claim 10
Dependent Claim
18 words
The electrical socket set forth in claim 1, wherein said body and said legs are formed of plastic.
Claim 11
Dependent Claim
23 words
The electrical socket of claim 1, further comprising a pair of retaining means for respectively holding said legs in the locking positions thereof.
Claim 12
Dependent Claim
24 words
The electrical socket set forth in claim 1, and further comprising a pair of retaining means respectively on the free ends of said legs.
Claim 13
Dependent Claim
23 words
The electrical socket set forth in claim 1, and further comprising a pair of pins respectively pivotally connecting said legs to said body.
Claim 14
Dependent Claim
25 words
The electrical socket set forth in claim 1, wherein each of said contacts includes a strip portion and a U-shaped portion electrically and mechanically interconnected.
Claim 15
Dependent Claim
44 words
The electrical socket set forth in claim 13, wherein each of said contacts further includes a nib on said strip portion which projects into the associated channel, said nib being respectively aligned with the associated finger in the locking position of the associated leg.
