  • Patent number: 8599103
    Abstract: The disclosure provides a terminal structure that includes an upper board and a lower board, which are adjacently provided and with respect to one another with a gap interposed therebetween. A conductor is formed on a rear surface side of upper board. A hole or a notch having an attached terminal is formed in lower board while penetrating through the lower board, and the terminal is electrically connected to the conductor on the upper board. The terminal includes a spring plate and a support section supporting the spring plate. The support section includes a fixing section that is fixed to lower board and a bottom plate that is positioned at a bottom surface side of lower board on a lower end side of the hole or notch. The spring plate of the terminal is formed to be connected to bottom plate and rise from bottom plate. The spring plate is extended upward from the lower end side of the hole or notch and comes into contact with conductor of upper board at an extended top position.
    Type: Grant

  • Patent number: 7505003
    Abstract: A card device includes a card case, a circuit board disposed in the card case, and an antenna rotatably disposed on the outside of the card case. An antenna rotating shaft is disposed on the base end of the antenna and inserted from the outside into the inside of the card case through a through-hole of the card case such that the antenna rotating shaft extends along the surface of the circuit board and is supported within the card case with the inner part of the antenna rotating shaft being spaced apart from the circuit board and the antenna rotating shaft being freely rotatable. A feed terminal having elasticity that urges the feed terminal against the antenna rotating shaft is disposed between the antenna rotating shaft and a part of the circuit board facing the antenna rotating shaft. The feed terminal is fixed to an antenna connection part of a circuit formed on the circuit board facing the antenna rotating shaft. The feed terminal is urged by its elasticity into contact with the antenna rotating shaft.
