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
