PURPOSE: To reduce cross talk and noise entering a transmission signal as much as possible by covering the periphery of specified one among built-in contact pins of a multipole connector with an inner ground pin having a cylindrical portion. CONSTITUTION: A digital communication connector pin 11, a power source and GND contact pin 12, and an audio contact pin 13 are contained in a board side multipole connector 1 mounted on a wiring board 100 via a base mold 2, and an inner shield 4 and a shielding cover 5 are provided thereon. The respective contact pins 11 to 13 are respectively fitted and connected to the socket type contact pins 31 to 33 of a cable side multipole connector 20. The periphery of a specified one, for instance, the audio contact pin 13 among the contained contacts is covered by an inner ground pin 15 having a cylindrical portion. On the contact pin 33 corresponding the same, a cylindrical ground pin 40 covering the periphery thereof is provided so as to conduct shielding. |
