Abstract

The invention provides a PCB cantilever beam signal transmission structure which comprises a PCB. A cantilever beam structure through hole is formed in the PCB, a coaxial signal transmission structureand a fixing piece are arranged at the two ends of the PCB respectively, and the fixing piece penetrates through the cantilever beam structure through hole, is matched with the coaxial signal transmission structure and fixes the coaxial signal transmission structure to the PCB. The structure is lower in cost, higher in applied emission frequency and better in performance, is capable of floating in the axial direction and the radial direction and is convenient to install.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a signal transmission structure of a PCB board cantilever beam. Background technique [0002] The background and impetus for board-to-board coaxial connectors to be more and more widely used come from two major development trends in the wireless equipment market: smaller size and lower price. Smaller, lighter, and cheaper are also the development trend of the wireless equipment market. Traditional small RF board-to-board coaxial connectors do not allow any tolerances, especially board-to-board axial distance tolerances. The standard SMP, MMBX, and IMP "board-to-board" coaxial connectors developed later can only allow limited tolerances, and the allowable tolerance range is very small, and still requires precise positioning and matching. In practical applications, radial and axial tolerances must be considered in use and assembly. The radial tolerance is mainly to compensate ...
