Rotary connector

A rotary connector comprising:

• a case;
• and
• a rotor of a cylindrical shape which is arranged in the case to be able to be rotated with respect to the case, wherein
• the rotor has
• a plurality of conductive ring portions which respectively correspond to a plurality of channels, and
• a plurality of channel barriers arranged respectively between the plurality of conductive ring portions,
• each of the plurality of conductive ring portions includes
• a core wire ring,
• a first ground (GND) ring,
• a second GND ring,
• a first core wire barrier arranged between the core wire ring and the first GND ring, and
• a second core wire barrier arranged between the core wire ring and the second GND ring,
• the case has a plurality of connector portions which respectively correspond to the plurality of channels,
• each of the plurality of connector portions includes
• a connector,
• a core wire brush having one end side connected to the connector and another end side in contact with the core wire ring,
• a first GND brush having one end side connected to the connector and another end side in contact with the first GND ring, and
• a second GND brush having one end side connected to the connector and another end side in contact with the second GND ring,
• the first core wire barrier and the second core wire barrier have shapes in which a leakage radio wave, from the core wire brush in contact with the core wire ring between the first core wire barrier and the second core wire barrier, is hindered from reaching another channel,
• the first core wire barrier has a shape in which a diameter on a core wire brush side is greater than a diameter on a first GND ring side, and
• the second core wire barrier has a shape in which a diameter on the core wire brush side is greater than a diameter on a second GND ring side.
