  • Publication number: 20230101925
    Abstract: A communication device includes a communication connector, a communication control circuit, and a common mode filter. The communication control circuit controls communication that is established by way of the communication connector. The common mode filter is connected to each of the communication control circuit and the communication connector to relay the communication. Letting a wavelength corresponding to a clock frequency of an electric signal sent out from the communication control circuit be denoted as ?, an electrical length of a signal path at which resonance is produced by a reflected wave resulting from reflection of the electric signal by the common mode filter is closer to an even multiple of ?/2 than to an odd multiple thereof.

  • Patent number: 11375605
    Abstract: An electronic device includes a printed board, a frame for fixing the printed board, a connector fixed at a position along one side of a front surface of the printed board, and an electrically conductive member. An indented portion is formed at a position of the one side facing the connector. The electrically conductive member has a portion arranged in the indented portion, and is expanded and contracted in a direction along the one side and a thickness direction of the printed board by an external force. The electrically conductive member has an upper surface, a lower surface, and a side surface in contact, respectively, with a shell of the connector, one surface of the frame, at least one side-surface portion which is part of a portion forming the indented portion and extends along a direction crossing the one side. The electrically conductive member is electrically connected with a ground of the printed board via the side-surface portion.
