A waterproof simplex receptacle includes a main body and a front portion. The front portion includes a front surface and rear surface. Terminals are recessed rearwardly from openings formed in the front surface, and are connected to wires extending rearwardly from the main body. The front surface includes a first surface portion, in the vicinity of the openings, which is positioned forwardly from a second surface portion that is located generally outboard of the first surface portion. Optionally, the first surface portion may be in the form of outwardly-extending ridges around the terminal openings, a convex surface, or a sloped or slanted surface, for example, and configured to direct water or other liquids away from the terminal openings associated with the terminals.
