  The invention described in the claims of the present application includes a plurality of coaxial connectors connected to a coaxial cable in which a central conductor and an outer conductor surrounding the central conductor are covered with an outer insulator. And a coaxial connector assembly in which a plurality of coaxial connectors are fitted and connected to a plurality of counterpart coaxial connectors, respectively.

  For transmission of high-frequency signals between a plurality of electrical components, electrical devices, or electronic devices, a central conductor and an outer conductor that surrounds the central conductor through an internal insulator form a signal transmission path that is not easily affected by external noise. In many cases, coaxial cables are used that are covered with an external insulator. For example, when a coaxial cable is connected to a wiring board that handles high-frequency signals, the high-frequency signal is transmitted from the wiring board to the outside through the coaxial cable, or from the outside to the wiring board through the coaxial cable of the high-frequency signal. Transmission takes place.
