Bursting-proof ceramic window structure and coupler

The utility model discloses an anti-explosion ceramic window structure and a coupler. The anti-explosion ceramic window structure comprises a ceramic window frame unit and a coupling unit, wherein the ceramic window frame unit comprises an inner window frame, an outer window frame and ceramic pieces; the conductor choking unit comprises a tubular inner conductor choking piece and a tubular outer conductor choking piece; the two inner conductor chokes are different in length and are used for shortening the length difference between the inner conductor chokes and the outer conductor chokes; and the water-cooling fixed cylinder is inserted into the inner window frame and is fixed with the inner conductor choke by electron beam welding. According to the invention, by reducing the length difference between the inner conductor choke and the outer conductor choke, large stress on the ceramic chip caused by inconsistent size change due to thermal expansion and cold contraction during brazing is reduced, so that the r
