Connector set and connector

A first connector that couples with a second connector including a plurality of second connection terminals and a second anchoring terminal, the first connector comprising:

• a plurality of first connection terminals;
• and
• a first anchoring terminal connected to a ground potential,
• wherein, when the first connector and the second connector are coupled, the plurality of first connection terminals make contact with the respective second connection terminals at first contact portions and opposite sides of the first connection terminal contact the second connection terminal;
• the first contact portions of the plurality of first connection terminals are, when viewed from a first direction, enclosed in a rectangular ring having a first corner portion located in a plane defined by a second direction and a third direction, orthogonal to the second direction, and a second corner portion located on the other side of the connector in both the second direction and the third direction;
• an outer peripheral surface of the first anchoring terminal in the first corner portion has, when viewed from the first direction, a first surface that faces the second direction and a second surface that faces the third direction, and, in the second corner portion, a third surface that faces a direction opposite to the second direction and a fourth surface that faces a direction opposite to the third direction;
• and
• the first surface to the fourth surface make contact with the second anchoring terminal when the first connector and the second connector are coupled.

A connector set comprising

• a first connector and a second connector,
• the first connector including:
• a plurality of first connection terminals, each having a first contact portion;
• and
• a first anchoring terminal connected to a ground potential, and the second connector including:
• a plurality of second connection terminals, each having a second contact portion;
• and
• a second anchoring terminal connected to a ground potential,
• wherein, when the first connector and the second connector coupled by inserting the first connection terminals to elastically deform opposite sides of the second connection terminals, the plurality of first connection terminals and the plurality of second connection terminals respectively make contact at the first contact portions and the second contact portions;
• the plurality of first contact portions and the plurality of second contact portions are, when viewed from a first direction, enclosed in a rectangular ring having a first corner portion located in a plane defined by a second direction and a third direction, orthogonal to the second direction, and a second corner portion located on the other side of the connector in both the second direction and the third direction;
• an outer peripheral surface of the first anchoring terminal in a first corner portion has, when viewed from the first direction, a first surface that faces the second direction and a second surface that faces the third direction, and, in the second corner portion, a third surface that faces opposite to the second direction and a fourth surface that faces opposite to the third direction;
• an inner peripheral surface of the second anchoring terminal in the second corner portion has, when viewed from the first direction, a fifth surface that faces opposite to the second direction and, in the second corner portion, a sixth surface that faces opposite to the third direction, and a seventh surface that faces the second direction and an eighth surface that faces the third direction;
• and
• the first surface to the fourth surface make contact with the fifth surface to the eighth surface, respectively, when the first connector and the second connector are coupled.
