Patent number: 10651611Abstract: An L-type coaxial connector is connected to a coaxial cable including a central conductor and an external conductor, and includes a housing, a bushing, and a socket. The housing includes a housing main body, a back-side section, and a crimp section. The housing main body has a first cut section. The back-side section includes a lid section and an extending section extending from the lid section and above which the external conductor is placed. The crimp section extends from the extending section, and its leading end section is bent so as to be opposed to the extending section such that the coaxial cable is interposed therebetween. The extending section has a second cut section, and a joining member joining the external conductor and the extending section is present inside the second cut section.Type: GrantFiled: May 6, 2019Date of Patent: May 12, 2020Assignee: Murata Manufacturing Co., Ltd.Inventors: Daisuke Okada, Yoshihiro Himi, Katsumi Kohnishi

Publication number: 20140105549Abstract: A plug that can be produced without performing complicated axial alignment. The plug is provided at one end of an optical fiber and is removably attached to a receptacle. A metallic cover is fitted in the receptacle. A ferrule is molded integrally with the metallic cover to hold the optical fiber. An optical element module includes a photoelectric conversion element to be optically coupled to the optical fiber and a substrate on which the photoelectric conversion element is mounted. The optical element module is press-fitted in a space formed by the metallic cover and the ferrule.Type: ApplicationFiled: December 26, 2013Publication date: April 17, 2014Applicant: MURATA MANUFACTURING CO., LTD.Inventor: Katsumi KOHNISHI

Patent number: 8047871Abstract: An L-shaped coaxial connector manufacturable at low costs includes a housing having a cylinder portion and a back portion. The cylinder portion includes a first opening and a second opening, and the cylinder portion is in contact with an external conductor of a receptacle inserted from the first opening. The back portion is connected to the cylinder portion and covers the second opening. The housing is made of a metal plate. The diameter of a part of a bushing contained in the cylinder portion is equal to or smaller than the diameter of the first opening. The housing further includes a crimping portion extending from the back portion. The crimping portion fixes the bushing to the housing by being bent so as to face the back portion with the bushing therebetween.Type: GrantFiled: August 20, 2009Date of Patent: November 1, 2011Assignee: Murata Manufacturing Co., Ltd.Inventors: Katsumi Kohnishi, Susumu Hashimoto

Patent number: 7985076Abstract: A receptacle for coaxial connector includes an outer conductor having a tubular portion, a central conductor having a central-conductor contact portion extending in an axis direction in an internal space of the tubular portion, and an insulator holding the outer conductor and the central conductor in an insulating state. An overhanging region made of the outer conductor and the insulator overhangs in a direction perpendicular to the tubular portion of the outer conductor. In this overhanging region, the outer conductor includes outer-conductor overhanging portions, and the insulator includes an insulator overhanging portion. The outer-conductor overhanging portions and the insulator overhanging portion have substantially the same thickness.Type: GrantFiled: October 22, 2010Date of Patent: July 26, 2011Assignee: Murata Manufacturing Co., Ltd.Inventors: Takao Zuinen, Makoto Kitamura, Naoaki Fujino, Katsumi Kohnishi

Patent number: 7972174Abstract: A housing includes a cylinder portion, a back portion, crimping portions, and supporting portions. The cylinder portion has a first opening, a second opening, and a cut and can be in contact with an external conductor of a receptacle inserted from the first opening. The back unit covers the second opening. Each of the supporting portions is disposed on the cylinder portion. Each of the crimping portions extends from the back portion and is bent so as to face the back portion such that the supporting portion is disposed between the crimping portion and the back portion. An elastic portion is disposed between the crimping portion and the supporting portion.Type: GrantFiled: September 9, 2009Date of Patent: July 5, 2011Assignee: Murata Manufacturing Co., Ltd.Inventors: Yuichi Maruyama, Koji Saito, Katsumi Kohnishi, Susumu Hashimoto
