Abstract
The invention discloses a split terminal block, which comprises an outer base, inner bases, contact pieces, a cover plate, cover plate screws, screw components and square nuts. The split terminal block is characterized in that two ends of the contact pieces are connected with copper bars or cables, and grooves on the contact pieces are matched with projections on the inner bases so that the innerbases and the contact pieces can be positioned reliably. Projections on the lateral sides of the inner bases and grooves on the outer base are reliably fixed by mounting positioning parts while elastic hooks at the bottom of the inner bases are matched with a crossbeam on the outer base, and accordingly reliability in connection is improved. The screw components and the square nuts are connected so that matching torsion between the screw components and the square nuts can be increased and reliability in connection is improved. Compared with the prior art, the split terminal block has the advantages of compact structure, large contact area, fine heat radiation performance, simplicity in assembly process and convenience for users to us.
