ぞれ工夫が施されている。(Prior art) When connecting a coaxial cable and a connector, contact between the inner conductor and outer conductor and the connector is an important problem.If the contact between the terminal of the inner conductor or outer conductor and the connector becomes unstable, There is a problem that noise is generated from this part. Therefore, when connecting a coaxial cable and a connector, alignment of the inner conductor and outer conductor is very important. For example, in the case of the WF-H coaxial cable manufactured by Mitsubishi Cable Industries, Ltd., as shown in Figure 6. The end of the outer conductor 43 of the coaxial cable 4 is flared and sandwiched between the split clamp 51 of the connector 5 and the connector 52 to ensure contact. Efforts have been made to ensure that the terminals of the internal conductors 41 come into contact with the internal contacts 53 by cutting them with a file using a cutting gauge as shown in FIG.

な接触が得られるようになる。The operation of cutting out the end of the internal conductor of the WF-H coaxial cable using this conventional cutting gauge was carried out as follows. The conventional cutting gauge 3 shown in FIG. 4 has a cylindrical portion 31 into which an insulator is inserted.
and a perforated disc part 32 provided inside the tip of this cylindrical part 31 and having a hollow center, and the whole is integrally formed of steel. First, the outer conductor, insulator, and inner conductor of the WF-H coaxial cable are cut to predetermined dimensions, the outer conductor is flared, and then the cutting gauge 3 is cut as shown in FIG.
Insert the cable from the proximal end side. A hole is made in the center of the tip of the cutting gauge 3, through which an inner conductor 41 is inserted, and an outer conductor 43 and an insulator 42 are formed.
While pressing the end of the internal conductor 41 against the disc part 32 of the cutting gauge 3, connect the end of the internal conductor 41 protruding from the cutting gauge 3 to the tip surface of the cutting gauge 3 and the internal conductor 4.
File one end until it is flush. In this flush state, the inner conductor and the outer conductor are accurately aligned, and reliable contact with the connector can be obtained for both.

及ぼすという問題があった。(Problem that the invention aims to solve) However, since the conventional cutting gauge is made entirely of steel, it is softer than a file, and when it is ground to the same level as mentioned above, the cutting gauge gradually decreases. The area near the hole was also scraped off along with the internal conductor, and as the file was repeated several times, the area around the hole on the cutting gauge was scraped and worn away, making it impossible to cut the internal conductor to the specified dimensions. There was a problem in that it could no longer be maintained, and noise caused by the contact between the internal conductor and the connector was generated, which had an adverse effect.

If you file down the inner conductor end face until it is flush with the end face of the internal conductor, you will have to repeat the process of filing down the internal conductor because there is a disc made of carbide near the hole in the gauge. Even when cutting, the area near the hole of the cutting gauge does not wear out, and the internal conductor can always be cut to a predetermined size.

発生をなくすことができる。(Effects of the invention) The coaxial cable cutting gauge according to the invention has a disc made of a carbide plate near the hole in the gauge, so even if the internal conductor is repeatedly filed down, it will not cut. Since the area near the hole in the coaxial cable does not wear out and the internal conductor can always be maintained at the specified dimensions, the positional relationship between the internal conductor and external conductor can be made accurate, and the contact between the coaxial cable and the connector is ensured. This can eliminate the noise caused by this.
