  • Patent number: 11894639
    Abstract: 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.

  • Patent number: 11710921
    Abstract: The connector includes: an axial member that is a cylindrical conductor; a central contact disposed inside along a central axis of the axial member; an insulating member interposed between the axial member and the central contact and which holds the central contact; a first flange and a second flange provided on an outer peripheral surface of the axial member; and a metal spring provided along an outer peripheral surface of the axial member. The metal spring includes: a C-shaped metal spring body; curved parts; elastic pieces that extend from the curved parts so as to face an outer peripheral surface of the metal spring body; inner protrusions provided on an inner peripheral surface of the metal spring body so as to protrude inside the metal spring body; and outer protrusions provided on outer peripheral surfaces of the elastic pieces so as to protrude outside the elastic pieces.

  • Patent number: 11569614
    Abstract: 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.

  • Patent number: 9905968
    Abstract: In a coaxial connector with a floating mechanism, a housing of a socket includes a housing base portion and a housing movable portion which can move radially over a plug-side end face of the housing base portion with a socket-side center contact. A top side of a plug-side shell is fitted onto the housing movable portion. A socket-side shell integrally includes shell contact plate portions which are exposed from the plug-side end face of the housing base portion. An end of the plug-side shell is configured to come into contact with the shell contact plate portions.
