  • Patent number: 12126125
    Abstract: A coaxial RF connector system comprises RF connectors with inner and outer conductors providing a galvanic contact. An outer conductor of a first connector has a plurality of longitudinal slits forming a plurality of spring-loaded contact elements which contact a solid outer conductor of a second connector. The first connector has a centering sleeve which is one monolithic part with the outer conductor for centering the solid outer conductor of the second connector. An insulation sleeve is provided between the centering sleeve and the solid outer conductor. This prevents a galvanic contact and improves PIM.

  • Patent number: 9318843
    Abstract: An RF connector comprises a coupling nut for locking the connector to a mating connector and a locking ring. When tightening the coupling nut, it pushes on the locking ring, which again pushes on a protrusion of the connector, moving the connector into a mating connector. When the coupling nut is tightened, the locking ring acts as a stop to limit the movement coupling nut leaving a gap between the connector and the mating connector. Due to this gap, the connector may be rotated in a locked state.

  • Patent number: 9236694
    Abstract: A coaxial connector system comprises a coaxial plug connector and socket connector. The coaxial connectors have a center conductor defining a center axis of the connector and an outer conductor coaxial to the center conductor. The plug connector's outer conductor has a cylindrical shape with slits forming a plurality of spring loaded contact elements, while the socket connector's outer conductor is a cylindrical shape forming a contact surface. Furthermore, the connectors have a mechanical contact surface at a right angle to their center axis and distant from the spring loaded contact elements and the contact surface. Cylindrically precision centering means are provided at the connectors, which fit into each other and precisely align the center axis of the connectors resulting in reduced passive intermodulation. This design allows for further reducing contact gaps between the outer and inner conductors to further improve return loss at high frequencies.
