Patent number: 11619654Abstract: A probe for characteristic inspection of a connector includes a plunger, a coaxial cable, a flange, and a housing having an end portion on one side including an increased diameter portion. A recessed portion which receives the increased diameter portion is in an upper surface of the flange. The increased diameter portion has side walls in contact with or facing respective inner side surfaces of the flange partly, with the inner side surfaces forming the recessed portion, and a bottom wall in contact with an upper recessed surface of the flange that forms the recessed portion. The increased diameter portion has connection surfaces connecting the bottom and side walls and inclined inward from one of the side walls toward the bottom wall. Alternatively, the inner side surfaces each have a first surface inclined downward, and a vertical surface extending downward from the first surface to the upper recessed surface.Type: GrantFiled: May 13, 2021Date of Patent: April 4, 2023Assignee: Murata Manufacturing Co., Ltd.Inventors: Hajime Suemasa, Shinichi Kenzaki

Patent number: 8678836Abstract: An outer conductor portion includes an outer conductor and a pair of outer terminals. The outer conductor is formed into a substantially cylindrical shape extending in the z-axis direction. The outer terminals are drawn toward the positive z-axis direction side of the outer conductor. In a plan view in the z-axis direction, the outer terminals are each bent in a direction outwardly from the outer conductor, and face each other across the outer conductor. An insulator has two sides, an upper surface in contact with a positive z-axis direction-side end portion of the outer conductor, and a lower surface in contact with the outer terminals at the sides, and thereby is nipped by the outer conductor portion in the z-axis direction. A central conductor is attached to the insulator, and is provided in a region surrounded by the outer conductor.Type: GrantFiled: December 4, 2012Date of Patent: March 25, 2014Assignee: Murata Manufacturing Co., Ltd.Inventors: Shinichi Kenzaki, Yukihiro Kitaichi, Hiroki Wakamatsu, Takashi Maruyama
