Terminal end processing method and terminal end shielding structure of shielded cable, and light transmitting/receiving system using terminal end shielding structure

A terminal end shielding structure of a shielded cable, comprising:

• a first electrically-conductive tape as a first electrically-conductive thin film which is elastic and which is formed on a peripheral surface of an outer skin end portion of a free end side of a shielded cable;
• a shielding member folded on the first electrically-conductive thin film such that the shielding member contacts the first electrically-conductive thin film, the shielding member having no cut portion at the folded end thereof;
• a second electrically-conductive tape as a second electrically-conductive thin film which is elastic and is a separate body from the first electrically-conductive tape, the second electrically-conductive thin film being formed on the shielding member;
• and
• shielded cable nipping means for pressing and fixing a portion at which the second electrically-conductive thin film is formed,
• wherein the first electrically-conductive thin film is wound one time or more on the peripheral surface of the outer skin end portion, and at least an end portion of the second electrically-conductive thin film and a surface of the first electrically-conductive thin film are in physical contact and electrically continuous.

A signal transferring system comprising:

• a first signal transmitting/receiving module to which is connected a first shielded cable which transfers electric signals from an exterior;
• a second signal transmitting/receiving module to which is connected a second shielded cable which transfers electric signals from an exterior;
• and
• a signal transfer medium transferring signals between the first signal transmitting/receiving module and the second signal transmitting/receiving module,
• wherein a terminal end shielding structure of at least one of the first shielded cable and the second shielded cable comprises:
• a first electrically-conductive tape as a first electrically-conductive thin film which is elastic and which is formed on a peripheral surface of an outer skin end portion of a free end side of the shielded cable;
• a shielding member folded on the first electrically-conductive thin film such that the shielding member contacts the first electrically-conductive thin film, the shielding member having no cut portion at the folded end thereof;
• a second electrically-conductive tape as a second electrically-conductive thin film which is elastic and is a separate body from the first electrically-conductive tape, the second electrically-conductive thin film being formed on the shielding member;
• and
• shielded cable nipping means for pressing and fixing a portion at which the second electrically-conductive thin film is formed, and
• the shielded cable nipping means is a portion of a case of the first and second signal transmitting/receiving modules.
