た。 Conventionally, a coaxial cable connector having a corrugated corrugated tube as an outer conductor was disclosed in U.S. Patent No.
No. 4046451 is known, but such connectors had many drawbacks. That is, as shown in FIG. The tip is expanded with a central angle of about 90 degrees, and this expanded tip 3a is connected to the conical contact surface 7 in the insertion hole of the connector body and the conical pressing surface 9 at the tip of the fixture 8. The structure was such that it was clamped and held in place. Moreover, the connector body 6
and the fitting 8 are screwed together, and the fitting 8 is screwed into the insertion hole of the connector main body 6 while rotating.
The conical pressing surface part 9 was pressed against the expanded distal end part 3a, and cooperated with the conical contact surface part 7 to clamp and hold the conical pressing surface part 9.

点を有していた。 Therefore, it is difficult to widen the tip end 3a of the corrugated tube 3 into a flared shape, and it is especially difficult in the case of a small diameter size. And when attached to connector 5,
If the fitting 8 was excessively tightened, there was a risk that the tip 3a of the corrugated tube 3 would be damaged. In addition, as shown in the schematic diagram of FIG. 2, with respect to the axis A of the connector main body 6,
The axis B of the corrugated tube 3 is often inclined by a minute angle θ, and furthermore, the axis B of the corrugated tube 3 is eccentric by a minute dimension a with respect to the axis A, as shown in the schematic diagram of FIG. In either case, the tip 3a does not contact the conical contact surface 7 with uniform pressure in the circumferential direction, and only a part of the circumference contacts the conical contact surface 7, as shown in FIG. 2 or 3. If it does not touch, or even if it does, it will become unstable.
As a result, it had a major drawback in that electrical characteristics such as voltage standing wave ratio characteristics (VSWR characteristics) and noise characteristics deteriorated.

こととなる。 According to the illustrated embodiment of the present invention, since the rigid insulator 20 is fitted into the concave circumferential grooves 19 and 36 of the contact 17 and the connector main body 21 to be locked, only the connector 16 is connected. Even when the inner conductor 12 is stretched or subjected to stress in the direction of expansion and contraction, the relative position of the inner conductor 12 and the corrugated tube 14, which is the outer conductor, in the axial direction is reliably fixed and maintained. This has a great advantage in that it can effectively prevent accidents where electrical characteristics deteriorate due to sudden changes in impedance. moreover,
Since the extra gap E exists on the outer diameter side of the corrugated tube tip fitting part 37, even if the axis B of the coaxial cable 11 and the axis A of the connector 16 are eccentric, they can be reliably and evenly spaced around the circumference. , are crimped and clamped by the vertical abutting surface portion H and the vertical pressing surface portion 40. Therefore, a connection with extremely excellent voltage standing wave ratio characteristics, noise characteristics, etc. can be realized.

However, since the corrugated tube tip clamping part 37 is pressed, the tip part of the corrugated tube 14 can be flared (expanded) even if it is not completely expanded to an angle along a plane perpendicular to the axis. The tip is always completely expanded to a plane perpendicular to the axis and clamped, making the tip flaring process easier. Moreover, by making the clamp 38 symmetrical in the front and rear, it can be easily inserted into the insertion hole 22 without worrying about the direction of insertion, and insertion errors are effectively prevented. Further, the sealing materials 44 and 48 prevent water from entering the coaxial cable 11 from the outside and maintain airtightness.

You are free to form it as you like. In addition to the above-mentioned clamp type tightening mechanism that tightens beyond the dead point, the tightening mechanism P includes a pair of circumferentially tapered grooved halves that tighten both outer flanges 23 and 49 from the outer diameter direction. It is also preferable to use one with a structure that draws the tsuba together.

ようなことも全くない。 As detailed above, the present invention provides a coaxial cable connector having a corrugated corrugated tube as an outer conductor, in which the connector body has an insertion hole into which the tip of the corrugated tube is inserted, and the connector body is perpendicular to the axis. A vertical contact surface part, on which a corrugated pipe tip fitting part which is expanded to a near plane where the pipe contacts, is provided as a stepped part in the middle of the insertion hole; a split clamp having a vertical pressing surface portion that presses the corrugated pipe tip clamping portion and clamps the clamping portion in cooperation with the vertical contact surface portion; Since the present invention has a fitting that is connected to the split clamp and presses the split clamp to the inner part of the insertion hole, the drawbacks of the prior art have been overcome and the intended purpose has been effectively achieved. Especially if you don't rotate the entire fixture.
The tightening mechanism allows for easy and quick installation. Furthermore, since the corrugated tube tip clamping part is clamped and held by the vertical contact surface and the vertical pressing surface, it is always clamped with an even pressing force in the circumferential direction, resulting in stable and excellent voltage standing wave ratio characteristics and Electrical characteristics such as noise characteristics can be obtained. Even if the axis of the connector and the axis of the coaxial cable are eccentric, the corrugated tube end clamping portion can be clamped with an even pressing force in the circumferential direction. Further, there is no possibility that the pressing force is weakened due to rotation of the fitting relative to the connector main body.
