Patent number: 6375488Abstract: A connector has a reduced height housing, and a reduced risk of breaking an electric wire. Electric wires Fc are connected by gripping pressure between connecting members 46 located at tips of arm members 42 of terminal fittings 40. When the terminal fittings 40 are in an attached state with a connector housing 10, the pair of arm members 42 are aligned in a width-wise direction of a flat cable F. Consequently, the height of the connector housing 10 can be reduced. Further, when the electric wires Fc are to be connected with the terminal fittings 40, these electric wires Fc merely need to be moved in a direction at a right angle to their direction of distribution until they are gripped between the connecting members 46. When this connection takes place, a pulling force is not exerted on the electric wires Fc in a length-wise direction. Consequently, breakage of these electric wires Fc can be avoided.Type: GrantFiled: October 2, 2000Date of Patent: April 23, 2002Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Yutaka Noro

Patent number: 6358101Abstract: The present invention relates to a connector wherein a retainer slides from a side direction of a connector housing in which it is to be installed. An object of the present invention is to provide a connector capable of preventing a connector connected in a condition in which the retainer is not installed, and transferred to subsequent processes. As a solution, a housing main body is provided with a slider capable of sliding, the slider is hooked in a regulating position in a condition in which the retainer is not installed on the housing main body, and interferes with detection pins provided on a male connector. Therefore the connection of both the connectors becomes impossible. To the contrary, when the retainer is installed on the housing main body, the slider is transferred from a regulating position to a permitting position by the slider contact part provided on the retainer which does not interfere with the detection pins, and the connection of both connectors is permitted.Type: GrantFiled: April 28, 2000Date of Patent: March 19, 2002Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yutaka Noro, Masamitsu Chishima, Matthew Grant

Patent number: 5816845Abstract: When a slide member of a connector is moved toward a provisionally-retained position, each slanting guided surface is moved into sliding contact with an associated slanting guide surface, and is guided by the guide surface, so that the posture of the slide member is inclined upwardly outwardly. During this movement, the slide member is not interrupted, and therefore an operator's fingers will not be disengaged from the slide member. Therefore, the slide member can be withdrawn in a single continuous motion. Additionally, another feature of the connector prevents a flat cable from being erroneously inserted into a slide member insertion space in a provisionally-retained condition.Type: GrantFiled: September 5, 1995Date of Patent: October 6, 1998Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Masamitsu Chishima, Yutaka Noro
