In some cases, a defect that causes a jump is generated, and in some cases, the above-described defect is found in a performance inspection immediately after construction. Among the causes of the defects in these conventional examples, the former has a structure in which the connector has many screwed tightening points, so that if the tightening order is wrong, the outer conductor is likely to be insufficiently clamped, so that the electrical characteristics are maintained for a long time. Of course, defects occur within a short period of time.In the latter case, if the cutting tool used to cut the outer conductor is old, bending or burrs may occur on the inner surface side of the cut outer conductor. There is no problem if the connector is attached after the bends and burrs are surely corrected and the inner diameter of the outer conductor is set within the specified dimensional tolerance.
If the cable is attached without this processing, the characteristic impedance of the cable is inconveniently generated, and a standing wave is generated, which causes leakage or diving of radio waves.

に防止することができる。As described above, the connector body is integrally provided with the connector body, and the movable pressing cylinder that is moved into the connector by the tightening of the tightening fitting is provided. With the tapered inner and outer edges, the outer conductor end, which is expanded into a trumpet shape, is strongly and reliably held, and the anti-pull-out strength is significantly strengthened.
Since the structure is such that the connection of these outer conductors and the conductor parts themselves are directly performed, the current flowing through the inner surface of the outer conductor is transferred to the connector body through the outer surface of the tapered cylindrical portion of the connector that surely makes surface contact with the inner peripheral surface of the outer conductor. Even if the flow loss is small due to the shortest path, and even if the cutting process of the outer conductor is insufficient, they are inevitably processed and corrected in the process of expanding the outer end part with a separate tool, and temporarily Even if a small foreign substance is present between the outer conductors and a small gap is generated to cause a current to flow on the outer surface of the outer conductor, it is grounded to the movable pressing cylinder that is pressed against the outer peripheral surface of the outer conductor, so that the leakage or mixing of radio waves is completely prevented. Can be prevented.

い。Also, since the electrical connection, waterproofing and anti-pulling-out measures can be taken only with one screw-fastening point, the workability is improved and the external conductor is not attached due to an error in the tightening procedure. A situation of insufficient holding is unlikely to occur.
