Patent number: 7500860Abstract: A lever type connector in which a connector holder is reliably fit into a receptacle holder to prevent a half-fitting is provided. In the lever type connector, a restricting recess is provided on the front side of an arm plate of a lever, and below a multiple force recess. When a connector holder is inserted into the receptacle, a rear surface of the restricting recess abuts to a rear surface of a receiving portion to restrict rotation of the lever. Then, when the connector holder is pushed down to the standby position where the receiving portion is inserted into the multiple force recess, the restricting recess is away from the rear surface of the receiving portion, so that restriction of rotation of the lever is cancelled.Type: GrantFiled: October 18, 2007Date of Patent: March 10, 2009Assignee: The Furukawa Electric Co., Ltd.Inventors: Yoji Tajiri, Toshihiro Yoshida, Yasuharu Suruga, Katsunori Takeda, Takeshi Watanabe, Hiroshi Kobayashi

Patent number: 7445475Abstract: A lever connector is provided where fitting of a connector holder is reliably performed by rotation of a lever, so that workability is excellent. In a connector holder 2, a provisionally-retaining claw 17 is provided to be elastically held by a first retaining portion 14 at a predetermined rotating position in order to restrict rotation of the lever 5. In a receptacle connector 3, a pressing projection 23 is provided to move the provisionally-retaining claw 17 to a retracted position where the provisionally-retaining claw 17 is not held by the lever 5 in a state that the connector holder 2 is at a standby position, so that restriction of rotation of the lever 5 is cancelled. On the other hand, an abutting surface of the first retaining position 14 of the lever 5 is of a mountain-like shape including a restricting surface 19 and a guiding surface 20.Type: GrantFiled: October 18, 2007Date of Patent: November 4, 2008Assignee: The Furukawa Electric Co., Ltd.Inventors: Yoji Tajiri, Toshihiro Yoshida, Yasuharu Suruga, Katsunori Takeda, Takeshi Watanabe, Hiroshi Kobayashi
