Patent number: 11754792Abstract: This connector (100) is provided with a locking member (200), a receiving part (192), an additional elastic part (420) and a pressing member (440). The locking member (200) comprises a supporting part (220) and a locking part (250). A mating-side connector (600) is provided with a mating-side locking part (660) and an abutting part (632). In the fitted state, the locking part (250) applies backwards force on the mating-side locking part (660) with the elasticity of the supporting part (220). The abutting part (632) is positioned in front of the receiving part (192), is pressed against the receiving part (192), and is restricted from moving backwards by the receiving part (192). When the pressing member (440) is in a first position, the additional elastic part (420) is interposed between the supporting part (220) and the pressing member (440), presses down the supporting part (220), and maintains pressing of the locking part (250) against the mating-side locking part (660).Type: GrantFiled: September 10, 2019Date of Patent: September 12, 2023Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yuichi Koreeda, Hideto Shimazu, Masaki Ishiguro

Patent number: 11336056Abstract: A connector device comprises a connector and a mating connector. Under a mated state where the connector and the mating connector are mated with each other, the mating connector is positioned forward of the connector in a front-rear direction. The connector comprises at least one supporting portion, at least one lock portion and a receiving portion. The mating connector has at least one mating lock portion and an abutment portion. At least one of the lock portion and the mating lock portion has an intersecting surface which intersects with both the front-rear direction and a perpendicular direction. Under the mated state, the abutment portion is positioned forward beyond the receiving portion in the front-rear direction and is brought into abutment against the receiving portion by a rearward force so that a rearward movement of the abutment portion beyond the receiving portion is regulated by the receiving portion.Type: GrantFiled: April 3, 2019Date of Patent: May 17, 2022Assignee: Japan Aviation Electronics Industry, LimitedInventors: Yuichi Koreeda, Masaki Ishiguro, Hideto Shimazu, Osamu Hashiguchi

Patent number: 11249258Abstract: A connector includes a cable holding portion, a first holding member having a first male screw portion and a first guide portion, an optical connector, an optical module, a second holding member having a second male screw portion and a second guide portion, and a coupling nut having a female screw portion. In cooperation with each other, the first and second guide portions allow a relative movement of the first holding member with respect to the second holding member in the front-rear direction while regulating a relative movement of the first holding member with respect to the second holding member in a circumferential direction about an axis parallel to the front-rear direction. Relative positions of the first holding member and the second holding member in the front-rear direction are maintained by the female screw portion being meshed with both of the first and the second male screw portions.Type: GrantFiled: January 22, 2019Date of Patent: February 15, 2022Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Yuichi Koreeda, Hideto Shimazu, Masaki Ishiguro

Patent number: 10754090Abstract: A plurality of optical fiber groups are housed in an optical fiber cable and which of the optical fiber groups optical fibers, which constitute the optical fiber groups, belong to can be identified depending on a covering of the optical fibers. Each of optical connectors (plug, receptacle) which are respectively attached to both ends of the optical fiber cable has regions, in which insertion holes in which the optical fibers are inserted and fixed one by one are formed to be arranged in a predetermined interval, in the same number as the number of the optical fiber groups, and even though the optical fibers in one optical fiber group are inserted and fixed in the insertion holes in an identical region, an arrangement order of the optical fibers in the region of the optical connector provided on one end is not maintained as an arrangement order of the optical fibers in the region of the optical connector provided on the other end.Type: GrantFiled: December 1, 2015Date of Patent: August 25, 2020Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Yuichi Koreeda, Hideto Shimazu, Masaki Ishiguro
