Power distribution terminal blocks, including power distribution block, distribution block into the power into the cable hole on the client has, the power distribution block has a qualifying connection holes on the electric side, the electric side was steppedThe outlet connection hole is set at each ladder was layered arrangement.

The distribution of input wires to be installed on the side line into the power of the power distribution block connection hole outlet side connection hole was the ladder hierarchical arrangement, the more connections can be set in a smaller volume in the same connection number and current size at the same time, the present invention and distribution terminals occupied space is greatly reduced, at the same time, the volume reduction also lower production costs, and help conserve resources, and connection terminals showed a ladder distribution, convenience staff wiring operation.
