Patent number: 6500023Abstract: An electrical connector for a cable such as a ribbon cable used in an electronic instrument. The electrical connector plugged into a connector of a printed circuit-board of, for instance, a notebook computer has substantially an inverted U-shaped handle with its pair of leg elements being engaged with socket elements formed in the sides of the connector. The leg elements are bent at about the mid points so as to reduce the height of the handle, thus allowing the handle to be fit within narrow interior space of the notebook computer.Type: GrantFiled: September 19, 2000Date of Patent: December 31, 2002Assignee: Jae Electronics, Inc.Inventors: Nina Duong, Tadashi Ishiwa

Patent number: 5945727Abstract: An electrical contact (10b) comprises a pin contact portion (1b), a press-fit portion (2b), and a terminal portion (3b) integrally formed from a metal sheet which has a flat surface defined by X and Z directions and a predetermined thickness in a Y direction. The press-fit portion as a first flat portion extends in the Z direction with a first end (2b.alpha.) and a second end (2b.beta.) opposite to each other. The pin contact portion extends from the first end in the X direction. The terminal portion as a second flat portion extends from the second end continuously in the X and the Z directions with a leg portion (3b.alpha.) extending in the Z direction and a foot portion (3b.beta.) extending from the leg portion in the X direction. The foot portion serves as a connecting portion to be connected to a conductive portion formed on an electrical circuit board.Type: GrantFiled: March 29, 1996Date of Patent: August 31, 1999Assignee: Japanese Aviation Electronics Industry, Ltd.Inventor: Tadashi Ishiwa

Patent number: 5695351Abstract: A release mechanism comprises an ejector formed on a frame member to be movable forward and backward, and a lever rotated in response to a forward movement of the ejector to release a mating connector from conductive contacts. The ejector is located in an opening of the frame member in a normal condition in which the mating connector is inserted in the from member. The ejector is protruded outside the opening only start of releasing operation of the mating connector. The ejector has a first mode enabling a predetermined forward movement and a second mode disabling the predetermined forward movement. The release mechanism further comprises members for cancelling the first mode and putting the ejector into the second mode after the mating connector is released from the conductive contacts, and members for restoring the first mode of the ejector from the second mode in response to an external operation of the ejector while the mating connector is connected to the conductive contacts.Type: GrantFiled: July 18, 1995Date of Patent: December 9, 1997Assignee: Japan Aviation Electronics Industry, Ltd.Inventors: Akira Kimura, Tadashi Ishiwa
