ABSTRACT:
The present invention relates to a connector which includes a plug unit and a receptacle. The plug unit includes a housing board and a transmission path board. The housing board has a housing board body and first connection terminals and second connection terminals. The transmission path board has a transmission path board body, plural differential signal patterns which are connected to the first connection terminals and the second connection terminals of the housing board, and high pass filters which are connected to each of the differential signal patterns. The receptacle has a receptacle body and pin contacts. According to the present invention, a low-frequency component of a digital signal is attenuated. Thus, since an attenuation factor of the high-frequency component and an attenuation factor of the low-frequency component of the digital signal can be set substantially the same, the digital signal can be transmitted surely.
