Abstract: A connector system includes a receptacle configured for mounting on a structure having a curved sidewall with an opening formed therein, such as an aerial vehicle having a curved skin with an access opening. The receptacle is configured so that the contacts of the receptacle are accessible from the exterior of the structure, through the opening; and the receptacle does not protrude above the outer surface of the sidewall. The connector system can further include a plug configured to mate with the receptacle to form an electrical connection. The plug can include a retractable shroud that protects the contacts of the plug when the plug is not mated with the receptacle.

Abstract: Receptacles are provided for mating with plugs to establish electrical connections. The receptacles include a shell having a body, and a flange attached to the body. The flange has a projection extending therefrom. The receptacle also has an electrically-insulating insert positioned at least in part within the body; and one or more electrical contacts positioned at least in part within the insert. The receptacle is configured for mounting on a panel. The projection contacts a mounting surface of the panel, to establish a localized contact area that provides bonding between the receptacle and panel.
