With the recent increase in speed and density of electronic devices, the noise level inside the device is increasing, and a technique for suppressing these at low cost is required.

あることを明らかにした。By the research and development so far, we have made it clear that it is important to take measures against what is generated from a connector in order to reduce unnecessary radiation from electric equipment. .

かにした。That is, when a signal current flows, a potential difference occurs at the GND pin due to the inductance of the GND pin portion of the connector. It was clarified that the outer conductor of the coaxial cable is driven by this potential difference, and a current flows through the outer conductor of the coaxial cable, which should originally be a shield, causing unnecessary radiation.

組み立て作業効率を上げるためにコネクタピンの部分を
平行２線構造にしている。In the connectors shown in FIGS. 7 and 8, the connector pins have a parallel two-wire structure in order to increase the degree of integration and the efficiency of assembly work.

発生する。However, the parallel two-line portion is a source of unnecessary radiation generated from the electronic equipment. That is, since the parallel two-wire portion has a large inductance, a potential difference is generated at the GND pin due to the inductance of the connector GND pin portion when a signal current flows. Due to this potential difference, the outer conductor of the coaxial cable is driven, and a current flows through the outer conductor of the coaxial cable, which should originally be a shield, causing unnecessary radiation.

However, the multi-core electric connector cable assembly requires an SCI connector for each coaxial cable, The SCI connector is housed in a metal shell, and a conductive elastic member is sandwiched between the outer conductor of the coaxial cable and the metal outer housing of the SCI connector and the metal shell, which is not easy to assemble. There was a problem.
