Receptacle for coaxial plug connector

A receptacle adapted for mating connection with a coaxial plug connector, said receptacle comprising:

• a dielectric mold having a cavity;
• an outer conductor shield being fitted on top of the mold and formed with an electrode socket for connection with an outer conductor tube of the coaxial plug connector, said electrode socket having a axis and a bottom at one axial end, the bottom being formed with a center opening communicating with the cavity of the mold, said outer conductor shield having a ground terminal lug projecting outwardly of the mold for electrical connection with an external circuit;
• a single spring member mounted to the mold and having a center electrode resiliently movable along the axis of the socket, said center electrode extending from the cavity through the center opening of the electrode socket for pressed contact with a center conductor post of the coaxial plug connector, said spring member carrying a movable contact which is disposed within the cavity and is movable together with the center electrode, said spring member having a first signal terminal lug projecting outwardly of the mold for electrical connection with the external circuit;
• and
• a single fixed contact member mounted to the mold and having a fixed contact which is normally engaged with the movable contact by the bias of the spring member and is disengaged from the movable contact when the center electrode is depressed by the center conductor post of the coaxial plug connector, said fixed contact member having a second terminal lug projecting outwardly of the mold for electrical connection with the external circuit.
