Abstract:
1. A housing frame of an electrical apparatus having two or more beams connected to each other, wherein each of the two or more beams includes a rectangular metal plate bent in a longitudinal direction so as to include a flat base portion and two flat side portions, the beams including: a first beam including rectangular metal plate bent twice in a longitudinal direction so as to include a flat first base portion and two mutually opposing flat first side portions adjacent to the first base portion, a cut portion being formed at a mid portion of only one of the flat first side portions; and a second beam including rectangular metal plate bent twice in a longitudinal direction so as to include a flat second base portion and two mutually opposing flat second side portions adjacent to the second base portion, the second beam being arranged perpendicular to the first beam in such a manner that an inner bent side surface of the second base portion faces a same direction as an inner bent side surface of the first base portion and is disposed on a same plane as the inner bent side surface of the first base portion; the housing frame further comprising: a connection member having a flat connection base portion extending from the inner bent side surface of the second base portion to the inner bent side surface of the first base portion through the cut portion formed in the one of the first side portions and overlapping with the first base portion and the second base portion; a first fastening member inserted through the connection base portion and the first base portion to fasten the connection base portion and the first base portion together; and a second fastening member inserted through the connection base portion and the second base portion to fasten the connection base portion and the second base portion together, wherein a mid portion of the first beam and an end portion of the second beam are connected in a T-shape by the connection member with the first and second fastening members, and angles between the first base portions and the first side portions or angles between the second base portions and the second side portions are acute angles.
