Combined synthesis electrical distribution box

The utility model discloses a combined type synthesized distributor box which comprises a box body. An apparatus mounting frame, a generatrix row, a zero-curve row, a grounding row and a feeder line are arranged in the box body; the generatrix row is transversely arranged in parallel, and a generatrix insulating frame which is adapted with the generatrix row is also arranged in the box body. The combined type synthesized distributor box has the advantages that the generatrix row is transversely arranged in parallel; once the distributor box is required for capacity expansion, only another distributor box is required to be connected at the side of a distributor box, or a plurality of transverse distributor boxes which are arranged side by side are directly produced when distributor boxes are directly produced; since the generatrix row is arranged transversely, status of circuit cross connection can not occur to the distributor box after the capacity expansion, in addition, the combined type synthesized distributor box is also suitable for bracket type installation and hanging type installation, has flexible installing mode, and occupies small area for distribution.
