A coaxial connector is provided for a coaxial cable having an inner conductor, a dielectric member and an outer conductor which is made of a metal thin film. The coaxial connector comprises a connector pin electrically connected to the inner conductor, a cylindrical connector body formed with a through bore having part of said connector member and one end portion of the coaxial cable received therein, a cylindrical housing rotatably mounted around and in concentric and radially spaced relation with the cylindrical connector body so as to have the cylindrical connector body and the coaxial cable held at a standstill to each other, a tubular conductor having a cylindrical wall portion having a thickness larger than that of the outer conductor of the coaxial cable. The tubular conductor is interposed between the inner surface of the body and the outer surface of the coaxial cable in concentric and radially spaced relation therewith. The coaxial connector further comprises a solder layer intervening between the inner surface of the tubular conductor and the outer surface of the coaxial cable. The solder layer has a thickness larger than that of the outer conductor of the coaxial cable and smaller than that of the tubular conductor, thereby allowing the outer conductor to be electrically connected to the inner surface of the one end portion of the cylindrical connector body by way of the tubular conductor.

Coaxial connector

Herein disclosed is a coaxial connector for connecting a coaxial cable to some device including another coaxial cable. The coaxial connector comprises a hollow ring-shaped member threaded with the coaxial cable and having an inner diameter which is slightly larger than an outer diameter of the coaxial cable. The hollow ring-shaped member has an annular cross section. The coaxial connector further comprises a cylindrical housing having a seat surface portion which allows the hollow ring-shaped member to be seated thereon, and pressing means for pressing the hollow ring-shaped member seated on the seat surface portion of the cylindrical housing to the cylindrical housing. The hollow ring-shaped member is transformed by the pressing means, thereby fixing the coaxial cable to the cylindrical housing.

In a coaxial cable comprising a cylindrical conductor tube structure, a cylindrical core conductor arranged within the conductor tube structure, and a dielectric member provide between the conductor tube structure and the core conductor, the conductor tube structure is constituted by a cylindrical outer conductor and a cylindrical inner conductor provided within the outer conductor in coaxial and radially spaced relationship with the outer conductor to be capacitively coupled with the outer conductor. The inner conductor has a first axial end portion protruded axially outwardly from one end of the outer conductor and a second axial end portion received in the outer conductor retracted axially inwardly from the other end of the outer conductor. The outer and inner conductors of the conductor tube structure are thermally insulated from each other thereby reducing heat transmission between the outer and inner conductors without lessening conductivity for high frequency signals.
