PURPOSE: An angle structure for distribution panel frame connection is provided to make possible three-way frame connection without unnecessary protrusion portions while being integrally formed, thereby eliminating portions protruded to the inside or the outside after the assembly of a distribution panel. CONSTITUTION: An angle structure for distribution panel frame connection is positioned in each corner of a hexahedral distribution panel to connect a horizontal frame(5), a cross frame(6), and a vertical frame(7). A first angle member(1) and a second angle member(2) are arranged in the lower corner of the distribution panel. A second fastening surface and a third fastening surface are integrally formed. A third angle member(3) and a fourth angle member(4) are arranged in the upper corner of the distribution panel. The second fastening surface, the third fastening surface, and a pickup ring plate are integrally formed. The first fastening surface, the second fastening surface, and a third fastening surface is the same as the width of a protruded surface which is fastenesd to a frame. The first fastening surface is supported by the supporting plate of a triangular shape. A plurality of protruded openings is formed on the fastening surface. |
