Connector device

A connector device comprising:

• a first connector;
• and a second connector fitted to the first connector,
• wherein the first connector comprises:
• a first contact comprising a first type contact and a second type contact configured to transmit a high frequency signal of a higher frequency than a signal transmitted by the first type contact, wherein the first contact is electrically connected to a conductor of a first board,
• an insulating first housing configured to hold the first contact, and
• a first shell comprising a first side portion and a bottom portion, wherein the first side portion surrounds an outer periphery of the first housing, wherein the bottom portion is continuous with an end portion of the first side portion in a direction close to the first board, wherein the bottom portion extends along the first board within a region surrounded by the first side portion, and wherein the first shell is electrically connected to a ground conductor of the first board,
• wherein the second connector comprises:
• a second contact electrically connected to a conductor of a second board,
• an insulating second housing configured to hold the second contact, and
• a second shell comprising a second side portion and an upper portion, wherein the second side portion surrounds an outer periphery of the second housing, wherein the upper portion is continuous with an end portion of the second side portion in a direction away from the second board, wherein the upper portion extends within a region surrounded by the second side portion, and wherein the second shell is electrically connected to a ground conductor of the second board, and
• wherein in a state where the first connector and the second connector are fitted to each other, the first contact comes into contact with the second contact, the first side portion comes into contact with the second side portion, and the bottom portion comes into contact with the upper portion.
