Novel high-speed coaxial connector

Abstract

The invention discloses a novel high-speed coaxial connector. The connector comprises an outer conductor; an insulator having a mounting hole penetrating the front and rear ends; the central terminal is fixed in the mounting hole in a penetrating manner; the central terminal comprises a contact area located at the head and a riveting line area located at the tail, and the riveting line area is used for being riveted and fixed with a metal wire core of a coaxial line and forming electrical conduction; on the premise that the size of a matching interface is kept unchanged, the material thickness of the wire riveting area is larger than that of the contact area, so that after the wire riveting area and a small-size metal wire core are riveted and fixed, the riveting cross section area is large, and a cross section cavity is reduced to compensate impedance mutation of other areas, so that the impedance matching of the whole product is balanced, and the purpose of improving the high-frequency performance is achieved; under the condition that the inner diameter of the outer conductor in the high-speed coaxial connector is kept unchanged, the high-speed coaxial connector is suitable for wires with smaller wire diameters, required high-frequency performance is achieved, signal data can be transmitted at a high speed, and the problem of insufficient high-frequency performance caused by the wires is solved.
