Coaxial connector device having main connector to which cable is connected and board connector to which main connector is connected

A coaxial connector device for electrically connecting a coaxial cable connector and a printed circuit board, the device comprising:

• a main connector;
• and
• a board connector to be mounted on a printed circuit board,
• the main connector including
• a conductive main connector body having a first fitting part for a coaxial cable connector at one end and a second fitting part at the other end;
• a center contact positioned, inside the main connector body, on a side with the first fitting part;
• and
• a card edge substrate positioned, inside the main connector body, on a side with the second fitting part, the card edge substrate being electrically connected to the center contact,
• the board connector including
• a board connector body in which a slot is formed, the board connector body being provided with a plurality of contacts in the slot;
• and
• an outer conductor contact provided in the board connector body,
• wherein, when the second fitting part of the main connector is fitted to the board connector, an end portion of the card edge substrate is coupled to the slot in the board connector body, a plurality of substrate contacts included in the card edge substrate electrically contact the plurality of contacts of the board connector body, and the second fitting part of the main connector body electrically contacts the outer conductor contact.
