Lower static contact seat of drop-out fuse

The invention relates to a lower static contact seat of a drop-out fuse. The lower static contact seat comprises a lower static contact seat body and hanging hook heads. The lower static contact seat body is a hollow box body which is provided with an opening towards the right end. The upper end face of the lower static contact seat body is provided with a T-shaped reinforcing rib. A vertical part of the T-shaped reinforcing rib is provided with an upper though hole penetrating through the upper end face of the lower static contact seat body. The lower end face of the static contact seat body is provided with a lower through hole corresponding to the upper through hole and penetrating through the lower end face of the lower static contact seat body. The lower end face of the lower static contact seat body is provided with two trapezoidal reinforcing ribs which are respectively arranged at the front side and the rear side of the lower through hole. The right ends of the front side wall and the rear side wall of the lower static contact seat body are respectively connected with one hanging hook head. The hanging hook heads are J-shaped hooks. The lower static contact seat of the drop-out fuse is advantageous by being high in structural strength, not liable to shift, simple in structure, and the like.
