  • Patent number: 10050379
    Abstract: The present invention provides a connector includes a housing having a fitting opening for the object to be connected, signal contacts retained in the housing in parallel disposition, a pressure member capable of pressing the signal contacts, and power source contacts. The power source contacts are retained besides the signal contacts, have a thickness dimension larger than that of the signal contacts and are to be pressed by the pressure member together with the signal contacts. The power source contacts include a power source contact with a fixation function, having not only the power source connection function but also a function of temporally fixing the object to be connected at a correct insertion position with respect to the signal contacts as well as a function of clamping and fixing the object to be connected in a state of being pressed by the pressure member.

  • Patent number: 9788426
    Abstract: A printed wiring board including: a first substrate on which a plurality of pads to be connected to a connector is arranged to form a front array and a rear array in two rows; a second substrate that is laminated on the first substrate and formed with first wirings connected to first pads of the front array and second wirings connected through vias to second pads of the rear array; engageable parts that are to be engaged with engagement parts of the connector; and one or more reinforcement layers that are provided at the frontward side in the connecting direction than the engageable parts of the first substrate and/or the second substrate. The wirings each have a part formed to have a constant width along the inserting direction to the connector and an expanded-width part expanded to have a wider width than the constant width in the inserting direction of the connector.
