PROBLEM TO BE SOLVED: To provide a digital interface plug reducing cross talk between plural cables. SOLUTION: Six-terminal plug 40 is provided at one end portions of two cables 10, 20, and four-terminal plug 50 is provided at the other end portions so as to form a four-terminal-six-terminal conversion interface. The six-terminal plug 40 has a power supply terminal and an earth terminal besides four signal terminals, and the power supply terminal and the earth terminal are insulated in a plug case 45. The four-terminal plug 50 has four signal terminals, and the shielding coatings 12, 22 of the respective cables 10, 20 are earthed via a plug case 52. A capacitor 48 for high frequency short-circuiting the plug case 46 and the shielding coatings 12, 22 of the respective cables 10, 20 is provided in the plug case 46 of the six-terminal plug 40, so as to reduce cross talk between the cables 10, 20. |
