[ What is claimed is:] [1.]1. A turn and lock electrical connector set comprising, in combination:a receptacle including a receptacle body having a lock washer thereon and an outer plug engagement surface for engaging a plug and a recess, said recess being defined by an inner peripheral wall of said receptacle body extending inwardly from said outer plug engagement surface and an end wall of said receptacle body adjoining said inner peripheral wall and spaced from said outer plug engagement surface, said receptacle additionally including receptacle electrical connectors located in said receptacle body, said end wall defining a plurality of openings communicating with said receptacle electrical connectors;a plug for selective attachment to said receptacle, said plug including a plug body having an outer receptacle engagement surface for engaging the receptacle, a projection having a distal end projecting outwardly from said outer receptacle engagement surface and a plurality of plug electrical connectors comprising spaced lock blades extending outwardly from the distal end of said projection, said projection being positionable in the recess of said receptacle to place said plug electrical connectors into the openings defined by the end wall of said receptacle, and subsequent relative rotational movement between said receptacle and said plug being effective to releasably lockingly engage said receptacle electrical connectors and said plug electrical connectors to prevent the plug from being pulled from the receptacle and to maintain the projection in sealing engagement with the inner peripheral wall of said receptacle body; anda seal comprising an O-ring seal disposed about said projection located between the receptacle and the plug for providing a liquid-tight seal between the receptacle and the plug when said receptacle electrical connectors and said plug electrical connectors are releasably lockingly engaged, said projection comprising a boss having a cylindrically-shaped outer peripheral wall, said outer plug engagement surface and said outer receptacle engagement surface being in engagement to resist passage of liquid into said recess when said receptacle electrical connectors and said plug electrical connectors are releasably lockingly engaged, and the inner peripheral wall of said receptacle body forming a flat radially inwardly projecting ledge engaged by said O-ring seal when said receptacle electrical connectors and said plug electrical connectors are releasably lockingly engaged to form a liquid-tight seal to prevent passage of liquid to said plug and receptacle electric connectors.
