Patent number: 7270556Abstract: A waterproof connector has a housing formed with holding portions capable of holding terminal fittings, and formed at one end with a fitting hole into which electric wires connected to the held terminal fittings are inserted; a waterproof plug having first electric wire insertion holes corresponding to the holding portions and fitted into the fitting hole; and a holder having a body portion preventing the waterproof plug from detaching from the housing and provided on the opposite side of the waterproof plug to the terminal fittings. The body portion of the holder is formed with second electric wire insertion holes into which the electric wires inserted into the first electric wire insertion holes are inserted. Further, the body portion is formed integrally with fitting protrusions that fit into the unused first electric wire insertion holes, thereby preventing drops of water from entering the housing through the unused first electric wire insertion holes.Type: GrantFiled: June 15, 2006Date of Patent: September 18, 2007Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Fumikatsu Mori, Harehide Sasaki, Yoshiaki Kato, Masato Minakata

Patent number: 7270557Abstract: A high-density storage device has a housing and a memory and controller assembly. The housing has a plug part and a socket part receiving the plug part of other high-density storage device. The memory and controller assembly is mounted in the housing and has a circuit board, a source controller integrated circuit and a memory integrated circuit. The circuit board has an upper surface and a bottom surface. The source controller integrated circuit is mounted on the bottom surface. The memory integrated circuit is mounted on the bottom surface of the circuit board. Because the source controller integrated circuit and the memory integrated circuit are mounted on the same side of the circuit board, so high-density storage device has a reduced size. Furthermore, the socket part may connect with another high-density storage devices.Type: GrantFiled: June 12, 2006Date of Patent: September 18, 2007Assignee: Walton Advanced Engineering, Inc.Inventor: Hong-Chi Yu
