  • Patent number: 10027073
    Abstract: The coaxial connector is provided with a contact, an internal housing, a shell and an electromagnetic shield plate. The contact has a connecting portion which can connect with a mating side contact, and a crimping portion which crimps the central conductor. The internal housing has a contact receiving chamber opened at a rear end portion, and the connector is retained in the contact receiving chamber. The shell has a shell main body covering an external perimeter of the internal housing, and a cable clamp. The cable clamp fixes an end of the coaxial cable. The shell main body has a lock piece. A pair of slits is provided at both sides of the lock piece. The electromagnetic shield plate is disposed at an upper face of the internal housing, and has one piece which shields a portion of the pair of slits with respect to the internal housing.

  • Patent number: 6979226
    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.
