Patent number: 10498082Abstract: There is provided a movable connector that more reliably suppresses pivotal motion of a connection target object at a contact section serving as the center of the pivotal motion. Further, reliable suppression of the pivotal motion of the connection target object at the contact section is achieved with no increase in the size of terminals. A contact section includes a first contact piece section having a first contact section that achieves pressing contact with a pin terminal T in a first direction, a second contact piece section having a second contact section that achieves pressing contact with the pin terminal T in the first direction in a position shifted from the first contact section toward the far side, and a contact receiving section that faces the first and second contact sections and has a contact surface section that comes into contact with the pin terminal T over the length thereof.Type: GrantFiled: June 6, 2018Date of Patent: December 3, 2019Assignee: IRISO ELECTRONICS CO., LTD.Inventors: Hitoshi Suzuki, Hiroaki Kobayashi, Yoshiyuki Ogura, Tomomitsu Saito, Daichi Shimba, Koji Kuniyoshi

Patent number: 10193260Abstract: A multi-contact connector includes terminals, which each include a first contact piece section, which has a first contact section, which achieves pressing contact with a pin terminal in a first direction, and a first elastic arm, which extends in a direction that intersects the first direction and displaceably supports the first contact section, and a second contact piece section, which has a second contact section, which achieves pressing contact with the pin terminal in the first direction, and a second elastic arm, which displaceably supports the second contact section. The second elastic arm extends in the first direction, which intersects the direction in which the first elastic arm extends, and an end portion of the second elastic arm or the end portion in the extending direction, that is, the front end facing the first elastic arm is formed as a spring piece linked to the second contact section.Type: GrantFiled: June 6, 2018Date of Patent: January 29, 2019Assignee: IRISO ELECTRONICS CO., LTD.Inventors: Hitoshi Suzuki, Hiroaki Kobayashi, Yoshiyuki Ogura, Tomomitsu Saito, Daichi Shimba, Koji Kuniyoshi

Patent number: 9997854Abstract: Connection reliability of terminals in a movable connector is enhanced. The movable connector includes a fixed housing having an abutment receiving portion and a movable housing having an abutment portion. When a pin terminal is fitted and inserted, the abutment portion abuts on the abutment receiving portion. This prevents arcuate curved deformation of the movable housing, and restricts a movable piece of a terminal at a center portion of the movable housing from being slightly stretched from the beginning of fitting and from constantly receiving load.Type: GrantFiled: January 24, 2017Date of Patent: June 12, 2018Assignee: IRISO ELECTRONICS CO., LTD.Inventors: Hiroaki Kobayashi, Yoshiyuki Ogura, Koji Kuniyoshi, Daichi Shimba

Publication number: 20160294089Abstract: At least one of a socket connector and a plug connector includes movable parts configured to elastically deform such that socket contact portions or plug contact portions at normal contact positions can be displaced in mating and unmating directions of the socket connector and the plug connector. A displacement load for displacement of the movable parts in the mating and unmating directions is set smaller than a load for positional displacement of at least the socket contact portions or the plug contact portions from the normal contact positions in the mating and unmating directions.Type: ApplicationFiled: March 31, 2016Publication date: October 6, 2016Applicant: IRISO ELECTRONICS CO., LTD.Inventors: Hiroaki Kobayashi, Yoshiyuki Ogura, Katsumasa Sato, Koji Kuniyoshi
