  • the second impedance adjustment terminal 26B By providing the second impedance adjustment terminal 26B, not only the internal terminal 20A at the end but also the impedance of the internal terminal 20B at the end can be adjusted. Thereby, the impedance shift as a whole of the plurality of internal terminals 20 can be adjusted more accurately.

  • the internal terminals 20A and 20B located at the ends are likely to cause an impedance shift between the internal terminals 20C other than the other ends, particularly in the use of high-frequency signals.
  • the provision of the impedance adjustment terminal 26 facilitates the shift. Can be suppressed.
  • the impedance adjustment terminal 26 can also function as a so-called “armor terminal” that prevents the resin in the connector from being scraped by the fitting of the male connector 4 and the female connector 6. Further, the impedance adjustment terminal 26 can arbitrarily change the frequency band of unnecessary resonance that causes deterioration of the VSWR characteristics.
