<p>An insulated antenna plug which is capable of effectively disconnecting noise and commercial high voltage to enter a terminal device such as a television receiver through a coaxial cable. The insulated antenna plug comprises one connector (1) which has one internal connection part (11) connected with the internal conductor of the coaxial cable, has one external connection part (14) connected with the external conductor of the coaxial cable, and is fixed via an insulating spacer (2) to the casing (3) forming a sealed space and made of a conductive member; the other connector (4) which is connected with the antenna plug of the terminal device via the other center conductor (21) and the other sealed case (22), which is fixed to the casing (3); a first capacitor (8) which is connected serially between the internal connection part (11) and the other center conductor (21) and disposed within the sealed space; and second capacitors (9) which are connected between the external connection part (14) and the casing (3) and disposed within the sealed space.</p> |
