Connector device

A connector device comprising a first connector and a second connector configured to be fitted to the first connector along a connection direction,

• wherein the first connector comprises:
• a plurality of conductive first contacts configured to be respectively connected to a plurality of conductors of a first board;
• an insulating first contact holding portion holding the plurality of first contacts;
• a conductive partition wall partitioning the first contact holding portion into a first grouping area that holds three or more first contacts, and a first individual area that holds a pair of first contacts for transmitting one signal and does not hold another first contact, wherein the partition wall is configured to be electrically connected to a ground conductor of the first board;
• and
• a conductive first surrounding wall disposed around an outer periphery of the first individual area so that the first surrounding wall and the partition wall at least partially surround the first individual area, wherein the first surrounding wall is configured to be electrically connected to the ground conductor of the first board,
• wherein the second connector comprises:
• a plurality of conductive second contacts configured to be respectively connected to a plurality of conductors of a second board and respectively contact the plurality of first contacts when the first connector and the second connector are fitted to each other;
• and
• a conductive second surrounding wall configured to be electrically connected to a ground conductor of the second board
• wherein each of the plurality of first contacts comprises:
• a first connecting portion for being connected to one of the plurality of conductors of the first board;
• a first contact portion that contacts one of the plurality of second contacts when the first connector and the second connector are fitted to each other;
• and
• a first linking portion that links the first connecting portion and the first contact portion along a first linking direction, and
• wherein the first linking direction in the first individual area intersects with the first linking direction in the first grouping area when viewed from the connection direction.
