The invention relates to the technical field of circuit breakers, provides an arc extinguishing chamber corrugated pipe and the vacuum arc extinguishing chamber, and solves the problems that in the prior art, the corrugated pipe is prone to instability and deflection and short in service life. The vacuum arc extinguishing chamber comprises a shell, a movable end assembly and a movable end cover; the arc extinguishing chamber corrugated pipe is arranged on the peripheral surface of a movable conductive rod in a sleeving mode; the arc extinguishing chamber corrugated pipe has a movable end connected with the movable end assembly and a static end connected with the movable end cover; the whole arc extinguishing chamber corrugated pipe is of a reducing structure, or the arc extinguishing chamber corrugated pipe has a reducing section in the axial direction; the diameter of the part, corresponding to a wave peak, of the whole arc extinguishing chamber corrugated pipe or the reducing sectionis gradually increased from the movable end to the static end, or, the whole arc extinguishing chamber corrugated pipe or the reducing section is divided into a plurality of unit sections in the axial direction; the diameters of the parts, corresponding to the wave peak, of the unit sections are consistent; and the diameter of the part, corresponding to the wave peak, of the unit section, close to the movable end, in the adjacent unit sections is smaller than the diameter of the part, corresponding to the wave peak, of the unit section close to the static end.
