Connector and connector device

A connector configured to be connected to a mating connector including a first mating terminal and a second mating terminal, the connector comprising:

• a housing;
• an outer shield fixed to the housing and surrounding a hollow space;
• a first terminal and a second terminal both which are held by the housing and surrounded by the outer shield in the hollow space, the first terminal and the second terminal being configured to be electrically connected to the first mating terminal and the second mating terminal of the mating connector, respectively;
• and
• an inner shield surrounded by the outer shield in the hollow space and disposed between the first terminal and the second terminal, wherein
• the connector is configured to be connected to the mating connector by moving toward the mating connector in a predetermined direction relatively with respect to the mating connector,
• the outer shield includes a first outer shield portion and a second outer shield portion which face each other across the hollow space in a facing direction perpendicular to the predetermined direction,
• each of the first outer shield portion and the second outer shield portion includes:
• an inner wall having a first inner circumferential surface and a first outer circumferential surface opposite to the first inner circumferential surface, the first inner circumferential surface facing the hollow space;
• an outer wall having a second inner circumferential surface and a second outer circumferential surface opposite to the first inner circumferential surface, the second outer circumferential surface facing the first outer circumferential surface of the inner wall across a gap in the facing direction;
• and
• a joining portion connecting the outer wall to the inner wall,
• the inner shield includes:
• a first tip region that faces the first outer shield portion or that is directly connected to the first outer shield portion;
• and
• a second tip region that faces the second outer shield portion or that is directly connected to the second outer shield portion,
• the first tip region of the inner shield is connected to the first outer shield portion via a first virtual path by a shortest distance,
• the second tip region of the inner shield is connected to the second outer shield portion via a second virtual path by a shortest distance,
• the outer shield, the inner shield, the first virtual path, and the second virtual path constitute:
• a plurality of first electrically-closed loops each passing the outer shield, the inner shield, the first virtual path, and the second two virtual path, the plurality of first electrically-closed loops surrounding the first terminal;
• and,
• a plurality of second electrically-closed loops each passing the outer shield, the inner shield, the first virtual path, and the second virtual path, the plurality of second electrically-closed loops surrounding the second terminal,
• the plurality of first electrically-closed loops include a first particular electrically-closed loop,
• the first particular electrically-closed loop does not surround any electrically-closed loop among the plurality of first electrically-closed loops other than the first particular electrically-closed loop,
• the plurality of second electrically-closed loops include a second particular electrically-closed loop,
• the second particular electrically-closed loop does not surround any electrically-closed loop among the plurality of second electrically-closed loops other than the second particular electrically-closed loop, and
• a longest loop length of loop lengths of the first particular electrically-closed loop and the second particular electrically-closed loop is shorter than a wavelength of a maximum frequency of transmission signals flowing through the first terminal and the second terminal.
