Inserting pare-connecting integration vacuum arc-extinguish chamber, which includes the upper and lower conductive poles, and the inside of the upper and lower conductive pole has the upper and lower contacts, one end of the upper conductive pole connecting with the actuator machinery, and a number of auxiliary contacts distributed uniform around the upper and lower conductive poles, which characterized by that there is the lower oriented pipe between the lower conductive pole and the vacuum chamber, and under the bottom of the lower conductive pole installed power storage springs, and the upper and lower contacts is cup shape, with the contact film on the cup mouth, and groove on the wall. The upper and lower contacts of the invention can all moveable, and the lower contact protrudes the assistant outer when brake off, and the power on and off can be realized between the pare-connecting upper and lower contacts. Therefore, the invention not only has the advantage that the vacuum arc-extinguish chamber can carry large current, but also can have the ability to cut on and off large current capacity.
