  • Patent number: 11545795
    Abstract: A connector includes: a cylindrical terminal to be electrically connected with a cylindrical counterpart terminal; an internal terminal located in the cylindrical terminal; and a housing holding the cylindrical terminal. The cylindrical terminal has a contact portion configured by bending a plate-shaped conductor into a cylindrical shape to contact one edge portion of the conductor with the other edge portion of the conductor. The one edge portion has a recessed shape at its circumferential end portion by reducing its thickness outwardly in a radial direction of the cylindrical terminal to configure one reduced thickness portion. The other edge portion has a recessed shape at its circumferential end portion by reducing its thickness inwardly in the radial direction to configure the other reduced thickness portion. The contact portion is configured by overlapping the one reduced thickness portion and the other reduced thickness portion.
