  • Patent number: 10008801
    Abstract: A pressure contact type connector includes: an upper flat plate portion; a lower flat plate portion which is disposed below the upper flat plate portion; a first spring portion which connects the upper and lower flat plate portions; and a second spring portion which extends upward from the lower flat plate portion and applies a resilient force to the upper flat plate portion, in which the first and second spring portions are wound about the upper flat plate portion when viewed from above in a plan view, and extend so that the spring portions do not interfere with each other when being compressed and extended in the vertical direction, the first spring portion is formed to be bent so that a width dimension is larger than a thickness dimension, and the second spring portion is formed to be bent so that a width dimension is larger than a thickness dimension.

  • Patent number: 7658649
    Abstract: A connector mechanism for a card, capable of being thinned, and a card adaptor having a connector mechanism for a card. A connector mechanism for a card, having an installation section (2a) in which a card (1) having external connection sections is installed and having a terminal member (9) with which the external connection sections of the card (1) can come into contact. The mechanism further has a lift-up mechanism including a projection section (2b) that once lift a front end section (1a) of the card (1) upward and then causes each of the external connection sections of the card (1) to be in contact with a corresponding one of the terminals (9a-9c) of the terminal member (9).
