トを設けたことを特徴とするFT型コネクタ。1. A first member fitted to a front end of a connector body.
One end is in contact with the second insulator and the other end is outside the conductor receiving portion of the center contact that holds a pin portion that partially protrudes to the outside by the insulator and the second insulator that contacts the first insulator. Provide a tubular insulator with a split collar having a taper surface on the outer peripheral surface of the part,
An annular elastic body that elastically presses the pin portion of the center contact is attached to the center of the front end of the second insulator, and an annular elastic body that elastically presses the inner peripheral surface of the connector body to the outer peripheral surface of the collar portion formed at the rear portion of the second insulator. A third insulator having an inner peripheral surface having a taper surface which is slidably contacted with the taper surface of the tubular insulator with a split collar, and is fitted into the connector body, and the tubular portion and the thick wall The thick-walled flange of the reinforcing sleeve formed of the flange is the third
Bending spring bodies are arranged along the axial direction at a predetermined distance near the base of the outer peripheral surface of the tubular portion of the reinforcing sleeve, and are positioned outside the tubular portion of the reinforcing sleeve. The inner clamp is formed with a slit so as to be constricted in the central part, and an uneven portion is formed on the inner peripheral surface of the inner clamp.
The outer clamp that slides in contact via the pad surface is loaded on the rear side of the connector body, and part of the outer clamp protrudes from the connector body and is located inside the tightening fitting that connects to the connector body.
A gasket for elastically pressing the outer conductor of the coaxial cable is attached to the rear part of the outer clamp, and a gasket for elastically pressing the outer sheath of the coaxial cable is provided in an auxiliary metal fitting connected to the rear part of the fastening metal fitting. FT type connector.
