Tripper housing and tripper with the housing

A tripper housing is disclosed, including a housing with an opening and a cover plate that covers the opening of the housing, the housing comprises a housing frame with a C longitudinal cross-sectional shape and first second side housings respectively arranged on the opposite sides of the housing frame, The housing frame and the cover plate are made of magnetic metal material, the first side housing and the second side housing are made of plastic, a fixing part is arranged between the housing frame and the cover plate, positioning projections are fixedly arranged on the first side housing andthe second side housing, and positioning grooves for embedding anf fixing the positioning projections are arranged on the housing frame. The invention has the following advantages and effects: the tripper housing reduces the production cost of the enterprise and ensures the structural strength of the housing; And the double magnetic fields are formed by the superposition with the magnetic field formed in the tripper, ther
