Description

  The present invention relates to a connector having a floating structure, and more specifically, it is used for a coaxial connector used for connecting a board and a board (or a panel, etc.). It relates to a coaxial connector.

  In general, a coaxial connector having a central conductor for connecting a coaxial cable or the like to an electronic device and an outer conductor such as a shield around the center conductor has a fitting gap (fitting floating) when the connectors are mutually fitted. If present, the characteristic impedance is disturbed and the high frequency characteristics cannot be maintained. As measures to prevent this, the following two have been proposed.

  First, in Patent Document 1, a floating connector having a floating structure formed of a coil spring, a slide piece, or the like outside the connector is used, and a fitting gap is not generated as long as the variation is within the coil spring or backlash. However, when both connectors, that is, plugs, jacks, and the like are fixed to a substrate or the like, a floating structure cannot be provided.

  On the other hand, the panel-mounted coaxial connector disclosed in Patent Document 2 has a structure in which an electrical connection is made to a central conductor via a spring. However, electrical connection via a spring or a spring has the property of electrically increasing the inductance component and blocking high frequencies.
