  • Patent number: 11031735
    Abstract: First terminals have a contact arm portion and second terminals have a convex contact point portion that is contactable with the intermediate portion of the contact arm portion of the first terminals in the direction of plugging and unplugging of the two connectors. The section of the contact arm portion of the first terminals that extends from the location of contact with the convex contact point portion of the second terminals to the free end portion of the contact arm portion in the direction of plugging and unplugging forms a stub portion. The sections of the first terminals other than the stub portion and the second terminals constitute a main transmission path. In a predetermined range that includes the location of contact in the main transmission path, the impedance of at least a partial range of said predetermined range is made smaller than the impedance of the stub portion.
