Abstract

A coaxial connector can be easily installed. The coaxial connector of this invention comprises a tube-like shell, which is attached to an end of a coaxial connector so as to rotate freely around the center of the core of the coaxial connector; the shell has an opening for inserting a coaxial female connector at an opposite end to the coaxial connector side; the inner peripheral face of the shell has a flat face, which is perpendicular to the axial direction, and a tapered face, which continues from the flat face; the diameter of the tapered face is narrow near the opening, and becomes larger toward the coaxial connector side end; at least two protrusions are provided in part of the tapered face, and project inwards from the diameter while extending in the axial direction; at least two substantially arc-like movable clips have screw grooves on their inner peripheral faces, the screw grooves meshing with screw threads of the coaxial female connector; the movable clips are arranged inside the shell so that one end face of each movable clip directly contacts the flat face in the shell, and the outer peripheral faces of the movable clips directly contact the inner peripheral face of the shell between the protrusions; an expanding spring is attached to the coaxial cable side end of the shell, and applies an active force so as to press the movable clips toward the flat face provided on the inner peripheral face of the shell.

Claims

1. A coaxial connector comprising:

a tube-like shell, which is attached to an end of a coaxial connector so as to rotate freely around the center of the core of the coaxial connector, the shell having an opening for inserting a coaxial female connector at an opposite end to the coaxial connector side, an inner peripheral face of the shell having a flat face, which is perpendicular to the axial direction, and a tapered face, which continues from the flat face, the diameter of the tapered face being narrow near the opening and becomes larger toward the coaxial connector side end, at least two protrusions being provided in part of the tapered face, the protrusions projecting inwards from the diameter while extending in the axial direction;

at least two substantially arc-like movable clips having on their inner peripheral faces screw grooves, which mesh with screw threads of the coaxial female connector, the movable clips being arranged inside the shell so that one end face of each movable clip directly contacts the flat face in the shell, and outer peripheral faces of the movable clips directly contact the inner peripheral face of the shell between the protrusions; and

an expanding spring, which is attached to the coaxial cable side end of the shell and applies an active force so as to press the movable clips toward the flat face provided on the inner peripheral face of the shell.

2. The coaxial connector as described in claim 1, comprising a face which is approximately perpendicular to the axial direction and stops the axial direction active force of the movable clips when the movable clips directly contact the inside of the shell near its opening.

3. The coaxial connector as described in claim 1, wherein the outer peripheral faces of the movable clips comprise cylindrical and tapered sections.
