Claim 1
Independent Claim
369 words
A polarized electrical outlet for receiving a male plug with polarized blades of dissimilar widths comprising: a body and a cap, said body and said cap each being formed of a thermoplastic material; said cap including a plate with first and second planar surfaces disposed on opposite sides thereof, said first planar surface adapted to butt against the rear of a panel; a crown having a generally rectangular rim integrally molded and disposed on the first planar surface; a first cap-aperture and a second cap-aperture disposed in said crown and passing through said plate, said first cap-aperture being wider than said second cap-aperture so as to receive the wider of said polarized blades; a web disposed between the exterior edges of said first cap-aperture and the rim of the crown, the width of the web between the ends of the first cap-aperture and the rim of the crown being substantially the same as the width of the web between the side of the first cap-aperture and the rim of the crown; said body having a central cavity therein and a mouth disposed at one end thereof and a pair of body-apertures disposed at the other end thereof; two arcuate contacts movably disposed within said cavity with their convex surfaces respectively in abutment with the opposed sides of said cavity and arranged directly beneath said cap-apertures, said contacts being narrowed at one end thereof to form shoulders with tabs extending therefrom, said shoulders being arranged to rest on the cavity and said tabs extending through said body-apertures; slotted recesses disposed in said cap for slidably engaging first ends of said contacts and the other ends of said contacts resting against the interior of said body, said contacts being free to expand lengthwise into said slotted recesses as the blades of a mating plug are inserted between the convex surfaces of the contacts and the opposed sides of the cavity; a third planar surface integrally molded and disposed on opposite sides of said mouth and arranged to butt said second planar surface in a parallel face-to-face association; and sealing means disposed on said second and/or third planar surface for bonding said second and third planar surfaces together and form the connector.

A polarized electrical outlet for receiving a male plug with polarized blades of dissimilar widths comprising: a body and a cap, said body and said cap each being formed of a thermoplastic material; said cap including a plate with first and second planar surfaces disposed on opposite sides thereof, said first planar surface adapted to butt against the rear of a panel; a crown having a generally rectangular rim integrally molded and disposed on the first planar surface; a first cap-aperture and a second cap-aperture disposed in said crown and passing through said plate, said first cap-aperture being wider than said second cap-aperture so as to receive the wider of said polarized blades; a web disposed between the exterior edges of said first cap-aperture and the rim of the crown, the width of the web between the ends of the first cap-aperture and the rim of the crown being substantially the same as the width of the web between the side of the first cap-aperture and the rim of the crown; said body having a central cavity therein and a mouth disposed at one end thereof and a pair of body-apertures disposed at the other end thereof; two arcuate contacts movably disposed within said cavity with their convex surfaces respectively in abutment with the opposed sides of said cavity and arranged directly beneath said cap-apertures, said contacts being narrowed at one end thereof to form shoulders with tabs extending therefrom, said shoulders being arranged to rest on the cavity and said tabs extending through said body-apertures; slotted recesses disposed in said cap for slidably engaging first ends of said contacts and the other ends of said contacts resting against the interior of said body, said contacts being free to expand lengthwise into said slotted recesses as the blades of a mating plug are inserted between the convex surfaces of the contacts and the opposed sides of the cavity; a third planar surface integrally molded and disposed on opposite sides of said mouth and arranged to butt said second planar surface in a parallel face-to-face association; and sealing means disposed on said second and/or third planar surface for bonding said second and third planar surfaces together and form the connector.
Claim 3
Dependent Claim
43 words
The polarized electrical connector according to claim 1 wherein a lip extends from said second planar surface around the perimeter thereof so as to form a container, said container being adapted to receive the mouth and the third planar surface of said body.
Claim 4
Dependent Claim
31 words
The polarized electrical connector according to claim 2 wherein said sealing means is an internal ridge disposed within said container at the juncture between said lip and said second planar surface.
Claim 5
Dependent Claim
66 words
The electrical connector according to claim 1 wherein a second web is disposed on the bottom of said cavity and extends between the concave surfaces of said arcuate contacts to insulate said contacts from each other and further wherein a boss is disposed on said second planar surface centrally between said body-apertures and arranged to engage the web which extends from the bottom of said cavity.
Claim 6
Dependent Claim
359 words
A polarized electrical outlet for receiving a male plug with polarized blades of dissimilar widths comprising: a body and a cap, said body and said cap each being formed of a thermoplastic material; said cap including a plate with first and second planar surfaces disposed on opposite sides thereof, said first planar surface adapted to butt against the rear of a panel; a crown having a generally rectangular rim integrally molded and disposed on the first planar surface; a first cap-aperture and a second cap-aperture disposed in said crown and passing through said plate, said first cap-aperture being wider than said second cap-aperture so as to receive the wider of said polarized blades; a web disposed between the exterior edges of said first cap-aperture and the rim of the crown, the width of the web between the ends of the first cap-aperture and the rim of the crown being substantially the same as the width of the web between the side of the first cap-aperture and the rim of the crown; said body having a central cavity therein and a mouth disposed at one end thereof and a pair of body-apertures disposed at the other end thereof; two arcuate contacts movably disposed within said cavity with their convex surfaces respectively in abutment with the opposed sides of said cavity and arranged directly beneath said cap-apertures; slotted recesses disposed in said cap for slidably engaging first ends of said contacts and the other ends of said contacts resting against the interior of said body, said contacts being free to expand lengthwise into slotted recesses as the blades of a mating plug are inserted between the convex surfaces of the contacts and the opposed sides of the cavity, said other ends of said contacts being disposed adjacent said pair of body apertures and arranged to receive lead-in wires threaded therethrough; a third planar surface integrally molded and disposed on opposite sides of said mouth and arranged to butt said second planar surface in a parallel face-to-face association; and sealing means disposed on said second and/or third planar surface for bonding said second and third planar surfaces together and form the connector.
