TECHNICAL FIELD

The present disclosure relates to a connector including a shield, and to a connector device including the connector.

DESCRIPTION OF RELATED ART

Japanese Patent Laid-Open Publication No. 2013-182808 discloses a connector and a shield cover covering the connector. The connector electrically connects a first circuit board to a second circuit board by engaging a socket installed on the first circuit board with a header installed on the second circuit board. The shield cover is engaged with an engagement portion formed on the first circuit board or the second circuit board. The connector includes plural contacts arranged in a single direction.

SUMMARY

A connector includes a housing, an outer shield fixed to the housing, a terminal held by the housing and surrounded by the outer shield, and an inner shield surrounded by the outer shield. The outer shield, the inner shield, and two virtual paths that connect the two tip regions of the inner shield to the outer shield by shortest distances, respectively, constitute plural electrically-closed loops surrounding the terminal. The electrically-closed loops include one or more particular electrically-closed loops. Each of the one or more particular electrically-closed loops does not surround any electrically-closed loop among the plurality of electrically-closed loops other than the each of the one or more particular electrically-closed loops. A longest loop length of the one or more loop lengths of the one or more particular electrically-closed loops is shorter than a wavelength of a maximum frequency of a transmission signal flowing through the terminal.

This connector reduces resonance of a transmission signal.
