Patent number: 11894639Abstract: There is provided a coaxial connector that can suitably bias a movable insulator to the side of a socket and maintain matched impedance. The coaxial connector includes a movable insulator that is fitted in a central conductor so as to be slidable and is housed in an insulator housing so as to be movable in an axial direction; and a biasing rubber member that is interposed between a partition disposed in the recesses of the insulator housing and the movable insulator. When the biasing rubber member connects the socket to the plug, the movable insulator is pushed in by a pushing force from a socket, and elastic pillars are bent in an arc shape.Type: GrantFiled: April 14, 2022Date of Patent: February 6, 2024Assignee: SMK CorporationInventors: Hirotaka Tsuchiya, Fumio Osawa, Tadahito Sasaki, Tsubasa Kanatani

Patent number: 11569614Abstract: Provided is a floating structure of a coaxial connector having a floating function and ensuring a reliable connection and water cutoff property are ensured. The floating structure of the coaxial connector includes: a plug introduction hole having an inner diameter larger than an outer diameter of the plug; an enlarged diameter hole communicating with the tip side of the plug introduction hole; a locking ring fixed in the enlarged diameter hole; a slider having a slide ring disposed movably in the axial direction and the axial radial direction; and an energizing elastic member that energizes the slide ring toward the locking ring. The plug body is coupled to the slider, and the plug body is held in the plug insertion part movably in the axial direction and the axial radial direction.Type: GrantFiled: June 24, 2021Date of Patent: January 31, 2023Assignee: SMK CorporationInventors: Hirotaka Tsuchiya, Fumio Osawa, Tadahito Sasaki

Patent number: 11398706Abstract: A connector includes: an internal contact disposed at an inner position in a radial direction; an external contact disposed at an outer position in the radial direction; and an insulator disposed between the internal and external contacts. At least one of the internal and external contacts includes, on one side in the axial direction, a mating part to be mated with a corresponding counterpart contact at a predetermined radial contact pressure. The insulator includes a first insulator part exposed to the one side in the axial direction, and a second insulator part disposed on the other side in the axial direction relative to the first insulator part. The first insulator part is made of an elastic material capable of being easily deformed elastically in the radial direction as compared to the second insulator part.Type: GrantFiled: September 17, 2020Date of Patent: July 26, 2022Assignee: SMK CorporationInventors: Hirotaka Tsuchiya, Norihide Taguchi, Tadahito Sasaki

Patent number: 10379307Abstract: Provided is an optical-electrical composite cable in which, even if the entire optical-electrical composite cable having an optical fiber routed along flexible flat wiring boards is made thin, the optical fiber is not deformed or damaged by a large bending stress. A pair of the flexible flat wiring boards are disposed on a front surface side and a rear surface side of the optical fiber, and a covering member integrates the entirety thereof. Thus, even if the optical-electrical composite cable is made thin, the cable is not bent with a large curvature without deformation of the optical fiber.Type: GrantFiled: July 24, 2018Date of Patent: August 13, 2019Assignee: SMK CorporationInventors: Tadahito Sasaki, Kohei Homma, Mitsuhiro Yoshida, Masayoshi Suzuki, Makoto Goto

Patent number: 10111332Abstract: A composite cable is provided which can connect a power line for feeding drive power to flat panel-shaped electric equipment and a signal line for outputting an electric signal to the electrical equipment at the narrow side surface of the electrical equipment. A flexible printed circuit board constitutes an end connection unit of the flexible composite cable to be connected to the electrical equipment, so that the composite cable can be connected to a side surface of the electrical equipment. Since the lateral width of the flexible printed circuit board is sufficiently long, a power trace is made thin and wide, so that the resistance value per unit length can be reduced and a current carrying capacity that allows the use of high power current can be adopted.Type: GrantFiled: August 23, 2017Date of Patent: October 23, 2018Assignee: SMK CorporationInventors: Tadahito Sasaki, Kohei Homma, Mitsuhiro Yoshida, Toyokazu Yoshino
