Patent number: 9281594Abstract: A connector comprising a first connector provided with first terminals each of which has a movable portion formed so that a dimension in its width direction is larger than a dimension in its thickness direction to be elastically deformed in a fore-and-aft direction (Y direction) of the connector, and a second connector provided with second terminals each of which has a movable portion formed so that a dimension in its thickness direction is larger than a dimension in its width direction to be elastically deformed in a width direction (X direction) of the connector. As compared with a terminal formed so as to be sufficiently elastically deformable in both of the fore-and-aft direction and the width direction of the connector, it is possible to increase a cross-sectional area of each of the movable portions, so that a permissible value of current of each of the terminals can be increased.Type: GrantFiled: August 26, 2013Date of Patent: March 8, 2016Assignee: IRISO ELECTRONICS CO., LTD.Inventors: Daisuke Funayama, Shigeru Mitsuzuka, Tomisaburo Yamaguchi

Patent number: 9178326Abstract: The movable portion of the first terminal of the first connector is formed to be larger in the width direction than in the thickness direction, so as to be elastically deformed in the front-back direction of the connector, and the movable portion of the second terminal of the second connector is formed to be larger in the thickness direction than in the width direction, so as to be elastically deformed in the width direction of the connector. Therefore, the movable portions can be formed with an increased cross-sectional area, thereby enabling the allowable current of the terminals to be increased, unlike a configuration in which the movable portion is elastically deformable to a sufficient extent both in the front-back direction and in the width direction of the connector.Type: GrantFiled: September 3, 2014Date of Patent: November 3, 2015Assignee: IRISO ELECTRONICS CO., LTD.Inventors: Daisuke Funayama, Shigeru Mitsuzuka, Tomisaburo Yamaguchi

Patent number: 8936496Abstract: Provided is a connector in which a decrease in contact pressure due to the shape degradation of the pressing portions does not occur even if the operation of rotating the pressing member is repeated. Since the connector main body has, at the rear end, supporting portions that rotatably support the pressing portion, the pressing portion rotates while butting the rear ends of the movable pieces and the supporting portions so that the rear ends of the movable pieces are pushed up by the pressing portion, the butting of the pressing portion and the supporting portions is contact between synthetic-resin components, this eliminates the pressing portion being cut off due to contact with the supporting portions even if the rotation of the pressing member is repeated, and hence the shape degradation of the pressing portion can be prevented.Type: GrantFiled: September 10, 2012Date of Patent: January 20, 2015Assignee: Iriso Electronics Co., Ltd.Inventors: Toru Takane, Kenichi Yamaguchi, Tomisaburo Yamaguchi

Patent number: 8480434Abstract: An electrical connection terminal arranged such that when the amount of displacement of one of a first contact portion and a second contact portion increases, a decrease in the contact pressure of the other contact portion is effectively suppressed, and a connector in which the electrical connection terminal is used. Between first and second elastic pieces and a fixed piece, a third elastic piece is provided such that when one of a first contact portion and a second contact portion is displaced in the direction of contact with a mating terminal, the amount of displacement of the other contact portion in the direction of contact with the mating terminal becomes smaller than the amount of displacement of the other contact portion in the insertion and removal direction of the mating terminal. Connection reliability by two-point contact may be improved.Type: GrantFiled: May 24, 2010Date of Patent: July 9, 2013Assignee: Iriso Electronics Co., Ltd.Inventors: Daisuke Funayama, Tomisaburo Yamaguchi
