Abstract:
A connector/switch unit for alternately connecting an earth circuit (208) respectively to an earth plane (203) or to the external casing (117) of a plug (116), and a radio frequency circuit (207) respectively to a antenna circuit (201) or to the core (119) of the said plug, this earth plane and antenna circuit being carried by one and the same insulating support plane (202) comprising a hole (220) for allowing said plug (116) to pass, wherein:the earth circuit (208) is connected to the said earth plane (203) by a first spring connector (105) distinct from the switching means of the unit, the support plane comprises a hollow cylindrical protrusion (213) comprising an internal cavity opening out in said hole (220), said hole comprises an oval hollow periphery adapted to the conical shape of said plug (116), the antenna circuit and the earth plane are extended towards the inside of the hole whilst matching said oval hollow periphery, the unit also comprises a second spring connector (204) placed in said internal cavity and comprising a central rod (224) provided with a collar and pushed in one direction by a spring element (225) in order to establish contact with the antenna circuit when said plug is removed, and to establish contact with said core by cutting off contact with the antenna circuit when said plug is pressed into the hole, pushing said rod in the other direction.
