Patent number: 7052316Abstract: The present invention provides an inexpensive card connector assembly which is used for the connection with two cards having mutually different transmission speeds, which can maintain transmission characteristics, and which is therefore suitable for high-speed transmission. The card connector assembly comprises first and second card connectors that are stacked for the connection with two cards having mutually different transmission speeds, and transmission paths for connecting the first and second card connectors to a circuit board. The transmission paths comprise a plurality of first and second terminal parts that respectively extend from the first and second card connectors, and a rigid board to which the first and second terminal parts are connected.Type: GrantFiled: November 23, 2004Date of Patent: May 30, 2006Assignee: Tyco Electronics AMP K.KInventors: Junichi Tanigawa, Doron Lapidot, Masayuki Aizawa, Tomoo Yamada

Patent number: 7018234Abstract: The present invention provides a card connector assembly that is used for the connection with two cards having mutually different transmission speeds and that can maintain transmission characteristics while minimizing the amount of an expensive FPC used. The card connector assembly comprises stacked first and second card connectors for connection with two cards having mutually different transmission speeds, and transmission paths for connecting the first and second card connectors to a circuit board. The transmission path for the first card connector to which a card with a relatively high transmission speed is to be connected is constructed from an FPC to which the first card connector is connected. The transmission path for the second card connector to which a card with a relatively low transmission speed is to be connected comprises terminal parts that extend from the second card connector, and a rigid board to which the terminal parts are connected.Type: GrantFiled: November 23, 2004Date of Patent: March 28, 2006Assignee: Tyco Electronics AMP K.K.Inventors: Junichi Tanigawa, Doron Lapidot, Masayuki Aizawa

Patent number: 6752633Abstract: The invention relates to an electrical cable for termination to an electrical component and method for termination that minimizes the mismatching of the differential impedance of a terminal part from which a shielding covering of an electrical cable has been stripped in a cable consisting of two differential transmission signal wires, a drain wire and a shielding covering that covers the electrical wire. Accordingly, a plastic heat-shrink tube is caused to adhere tightly to the terminal part and shielding covering, except for the stripped front end portion of the terminal part, so that the front end portion is exposed. As a result, the heat-shrink tube prevents or alleviates the mismatching of the differential impedance.Type: GrantFiled: October 24, 2001Date of Patent: June 22, 2004Assignee: Tyco Electronics.
