Abstract (en)
The plug has a capacitive part (C) and an inductive part (I) connected in series to form a resonator. The parts are connected mechanically and electrically by a connection unit (13). The part (I) has a wire core (8) to transmit a tightening torque, for connecting the parts, to a shell (2) composed by the part (C). The wire core has an enlarged part with shape and dimension complementary to inner shape of the shell. The inductive part has an envelope (6) whose outer surface covered with a layer of thickness about 30 to 50 micrometer of a material having high electrical conductivity, so that outer diameter of the inductive part is slightly increased.
