シールド効果しか得ることができなかった。For this reason, when the conventional connector is used, two connectors and one connecting cable are required, which not only complicates the configuration, but also originally has an effect of shielding the external space of the device. Despite adopting a double shield case structure to increase the
Unwanted signals enter from the mating part between the connector 5 or the connector 7 and the cable 6 or radiation of a local signal occurs, so that there is only a single shield effect against the leakage of the signal from the mating part. I couldn't get it.

すると同様の問題点が生じた。Although a noise-prevention type connector for eliminating intrusion of disturbing radio waves and radiation of unnecessary radio waves has already been proposed (see Japanese Patent Application Laid-Open No. 55-148376), even such a connector is doubled. The same problem occurred when trying to use it in a shield case.

It is an object of the present invention to provide a high-frequency signal interface connector and a method of mounting the same, which can greatly prevent the radiation of the above.

Transmission and reception can be performed with a single connector, and it is possible to prevent signal leakage from the mating portion of the cable when using two connectors. Further, by leak-tightening the nut at the portion where the tapped portion of the connector penetrates the outer shield case or by soldering, it is possible to prevent signal leakage from the through hole.

行われる。In the connector 4 according to the present invention, the length of the tapped portion 4a is made longer than that of the conventional connector so that the tapped portion 4a slightly protrudes from the outer shield case 3 to the outside.
That is, the length is set to exceed at least the distance between the inner shield case and the outer shield case, the thickness of the outer case, and the thickness of the nut. The connector 4 is attached to the outside of the inner shield case 2 of the high-frequency circuit unit 1 with a screw 11, and the pin 12 is connected to the high-frequency circuit unit 1 and the tapped portion 4a of the connector 4 is connected.
Is penetrated through the outer shield case 3 and is tightened by nuts 9a and 9b inside and outside the outer shield case 3. For this reason, the connection between the connector 4 and an external device (not shown) is made at the tip of the tapped portion 4a, that is, at the portion outside the outer shield case 3 and extending from the nut 9b.
