Abstract

An extension cordset assembly includes a receptacle and a sealing gasket. The receptacle includes a receptacle main body, a receptacle connecting interface and first and second spade mating holes extending into the receptacle main body from the receptacle connecting interface. The receptacle is configured to mate with a plug having a standard spade configuration. The sealing gasket is positioned on the receptacle connecting interface and includes first and second spade openings aligned with the first and second spade mating holes, respectively. The sealing gasket is configured to provide a water-resistant seal between the receptacle and the plug.

Claims

1. An electrical plug, comprising:

a main body having a connecting interface; and

a pair of electrical spades extending from said connecting interface,

wherein said main body comprises;

(a) threads on an outer surface thereof, said threads configured to threadably engage reciprocal threads formed within a connecting nut of a receptacle in order to securely connect the electrical plug to the receptacle; and

(b) a plurality of apexes, wherein said threads are located only at and proximate said plurality of apexes.

2. The electrical plug of claim 1, wherein an axial cross section of said main body is triangular.

3. The electrical plug of claim 1, wherein said main body further comprises a rim surrounding said connecting interface.

4. The electrical plug of claim 1, further comprising a ground pin extending from said connecting interface.
