らびに挿入損失の改善を期待できるものである。As described above, according to the present invention, the small-diameter cylindrical portion inserted between the insulator covering the inner conductor of the first coaxial cable and the outer conductor covering the insulator, and the second
Is provided with a connector body that is formed of a large-diameter tubular portion that surrounds the outer sheath of the coaxial cable and that communicates with the small-diameter tubular portion, and a large-diameter tubular portion is provided through the inner conductor of the second coaxial cable and the small-diameter tubular portion of the connector body A central contact is provided for connecting the inner conductor of the first coaxial cable pulled out to the inside of the large-diameter tubular portion of the connector body, and is formed at both ends of the central contact and inserted into the large-diameter tubular portion of the connector body. A spacer is provided to insulate the center contact from the connector body, and an inner crimp ring with a diameter smaller than the inner diameter of the large-diameter cylindrical portion of the connector body is attached to the outer circumference of the outer sheath of the second coaxial cable to provide a small diameter of the connector body. The outer conductor of the first coaxial cable is attached to the outside of the outer coating of the first coaxial cable attached to the tubular portion and is crimped to sandwich the outer conductor of the first coaxial cable with the small diameter tubular portion of the connector body A closing member that is provided with a crimping member, forms a notch in which the center contact is exposed in the large-diameter tubular portion of the connector body, and is attached to the large-diameter tubular portion of the connector body to shield the notch. Since the first coaxial cable whose tip has been processed is attached to the small-diameter tubular portion of the connector body, the tip-treated first coaxial cable is inserted into the large-diameter tubular portion of the connector body from the inner conductor and the small-diameter tubular portion. The inner conductor of the first coaxial cable pulled out to the large-diameter cylindrical portion is joined to the center contact arranged in the large-diameter cylindrical portion of the connector body from the notch formed in the large-diameter cylindrical portion of the connector body. After the treatment and the joining treatment, the cutout portion is shielded by a closing member. The outer conductor of the first coaxial cable and the small-diameter tubular portion of the connector body are connected by crimping a crimping member. The outer conductor of the second coaxial cable and the large-diameter cylindrical portion of the connector body are clamped by the large-diameter cylindrical portion so that the outer conductor of the second coaxial cable is sandwiched between the inner crimp ring and the large-diameter cylindrical portion. It is possible to prevent the deterioration of the standing wave ratio and improve the insertion loss due to the relay connection of the first and second coaxial cables.
