A novel wet-type integrated maintenance-free contact group disclosed by the present invention comprises a contact group shell, the front side and the rear side of the top of the contact group shell are fixedly provided with contact blocks, the right side of the contact group shell is fixedly provided with a sealing rear cover through a mounting groove and a positioning pin, and the left side of the sealing rear cover is fixedly connected with a sealing ring. Bearings are mounted on the two sides of the inner wall of the contact group shell, and a corrugated spring is mounted at the bottom of the right bearing. A framework oil seal is installed on the left side of an inner cavity of the contact set shell, a rotating shaft is arranged on the left side of the contact set shell, the right side of the rotating shaft penetrates into the contact set shell, and the surface of the framework oil seal makes contact with the surface of the rotating shaft. The inner wall of the bearing is fixedly connected with the surface of the rotating shaft. According to the novel wet-type integrated maintenance-free contact group provided by the invention, the design of open type grouping assembly of existing contact sheets and contact rings is canceled, and the novel wet-type integrated maintenance-free contact group has the advantages of integration and maintenance-free.
