Abstract: An electrical connector includes a receptacle and a plug. The receptacle includes a first annular flexible circuit board and first electrical contacts coupled to the first annular flexible circuit board, electrically isolated from each other, and arranged in at least one receptacle annular pattern. The plug includes a second annular flexible circuit board and second electrical contacts coupled to the second annular flexible circuit board, electrically isolated from each other, and arranged in at least one plug annular pattern. The plug is selectively connectable with the receptacle. When the plug is selectively connected with the receptacle, each one of the first electrical contacts of the receptacle is in physical contact with a corresponding one of the second electrical contacts of the plug.

Abstract: Examples of the present disclosure include an electrical connector. The electrical connector includes a plug. The plug includes a plug frame and plug ring-segment assemblies. The plug frame includes plug apertures. Each one of the plug ring-segment assemblies includes a plug ring-segment and a plurality of plug electrical contacts. The electrical connector further includes a receptacle. The receptacle includes a receptacle frame and receptacle ring-segment assemblies. The receptacle frame includes receptacle apertures. Each of the receptacle ring-segment assemblies includes a receptacle ring-segment and a plurality of receptacle electrical contacts. The plug is selectively connectable with the receptacle. When the plug is selectively connected to the receptacle, each one of at least some of the plug electrical contacts is in physical contact with a corresponding one of the receptacle electrical contacts.
