Patent attributes
Provided are a receptacle connector and a connector with simple structures, which include an added function such as a waterproofing function. The receptacle connector includes: a signal terminal that transmits signals between a plug connector side and an electronic substrate side in an extension direction; an insulating holder that has a circular column shape extending in the extension direction and that holds the signal terminal by being penetrated thereby; a conductive first shell in the form of a tube that covers the outer circumference in the radial direction, which is orthogonal to the extension direction of the holder; a non-conductive connector case having a cylindrical space that contains the first shell and extends in the extension direction; an inner seal member that seals the inner portion of the first shell in the extension direction; and an outer seal member that seals the inner portion of the cylindrical space in the extension direction.
