Abstract

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.

Claims

1. A coaxial connector for electrically and mechanically connecting a coaxial cable to a certain device,

said coaxial cable having a cylindrical inner conductor, a cylindrical outer conductor disposed in concentric and radially spaced relation with said inner conductor, and a dielectric member provided between said inner conductor and said outer conductor to encircle and support said inner conductor in coaxial relationship with said outer conductor,

said coaxial connector comprising:

a connector member having a center axis axially aligned with the center axis of said coaxial cable and electrically connected to said inner conductor;

a cylindrical body having one end portion and the other end portion having an inner diameter larger than that of the one end portion, said one end portion formed with a through bore having a center axis substantially coincide with said center axis of coaxial cable and disposed in concentric and radially spaced relation with one end portion of said coaxial cable, and said other end portion formed with a through bore having a center axis substantially coincide with said center axis of connector member and disposed in concentric and radially spaced relation with part of said connector member;

a tubular dielectric member disposed between said connector member and said cylindrical body;

a housing rotatably mounted around and in concentric and radially spaced relation with the cylindrical body so as to have said cylindrical body and said 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, and interposed between the inner surface of said body and the outer surface of said coaxial cable in concentric and radially spaced relation therewith; and

a solder layer intervening between the inner surface of said tubular conductor and the outer surface of said coaxial cable, and having a thickness larger than that of said outer conductor of said coaxial cable and smaller than that of said tubular conductor, thereby allowing said outer conductor to be electrically connected to the inner surface of said one end portion of said cylindrical body by way of said tubular conductor.

2. The coaxial connector as set forth in claim 1, in which said outer conductor of said coaxial cable is formed with a thin film so as to cover said dielectric member therewith.

3. The coaxial connector as set forth in claim 1, in which said tubular conductor has a linear expansion coefficient less than that of said outer conductor of said coaxial cable and more than that of said cylindrical body.

4. The coaxial connector as set forth in claim 3, in which said linear expansion coefficient of said tubular conductor is substantially same as that of said outer conductor of said coaxial cable.
