Patent number: 7445495Abstract: An electrical connector includes a housing (1) and a plurality of terminals (10) having parallel upper and lower arms (11, 12) that have projections (11A, 12A) between which a flat circuit board (F) is inserted for electrical connection to the terminals (10). The projection (12A) of the lower arm (12) has a sharp point.Type: GrantFiled: February 15, 2007Date of Patent: November 4, 2008Assignee: Hirose Electric Co., Ltd.Inventor: Yoshinori Takashita

Patent number: 7347720Abstract: When the movable member (30) is at the open position, the cam portion (33) of the movable member (30) is out of contact with the pressure receiving portion of a lever arm (21), making it possible to insert a flat cable into the connector on the contact side. When the movable member (30) is at the closed position, the cam portion (33) comes into contact with the pressure receiving portion that consists of a shoulder (21D) and a concave indentation (21B). While the movable member (30) is moving to the closed position, the cam portion (33) pushes the shoulder (21D) to provide the pressure receiving portion with the highest pressure. When the movable member (30) reaches the closed position, the cam portion (33) rests in the concave indentation (21B) while maintaining a pressure less than the highest pressure.Type: GrantFiled: August 3, 2006Date of Patent: March 25, 2008Assignee: Hirose Electric Co., Ltd.Inventor: Yoshinori Takashita

Patent number: 7255584Abstract: The latching metallic piece (12) has a lever-like arm (20) that extends in the direction of receiving the flat-type cable C. The lever-like arm (20) has a latching claw (20A) at one end, a fulcrum section (22) at the middle point, and an extending section at the other end. A pressuring member (14) has a restricting section that does not contact with the extending section (20B) of the latching metallic piece (12) at the open position, and that prevents the displacement of the extending section at the closed position. When the pressuring member is at the open position, the lever-like arm (20) is in the state that it can be freely displaced so as to allow insertion/removal of the flat-type cable. When the pressuring member is at the closed position, the displacement of the lever-like arm relative to the latching section in the direction that increases the latching of the latching claw (20A) is prevented, and the displacement of the lever-like arm in the direction that reduces the latching is prevented.Type: GrantFiled: September 28, 2006Date of Patent: August 14, 2007Assignee: Hirose Electric Co., Ltd.Inventor: Yoshinori Takashita

Patent number: 6666711Abstract: An electrical connector has a plurality of sheet-type terminals (20 and 30) which are received into corresponding receiving slots (11 and 12) of a housing (10) and are arranged parallel each other in a direction. The terminals (20, 30) have connection sections (23 and 33) at their ends, which are arranged so as to face the same side and protrude outward from a bottom surface of the housing. The movable member (40), which presses a flat cable (C) toward contact sections (26, 36), is movably supported at an open mouth of the housing (10). The connection sections (23 and 33) have connection surfaces (23A and 33A) for contact with circuit sections of a circuit board, which are staggered in a receiving direction of the terminals to the housing.Type: GrantFiled: April 11, 2002Date of Patent: December 23, 2003Assignee: Hirose Electric Co., Ltd.Inventors: Yoshinori Takashita, Mitsuo Ishida, Kazuhisa Tsunematsu
