ABSTRACT:
A rack for mounting a communication apparatus. The rack comprises a pair of right and left vertical side frames and a plurality of block-mounting plates for mounting at least one block which houses at least one printed board. The block-mounting plates are rectangular and are longitudinally disposed between the right and left vertical side frames. The at least one block is mounted on the front face of the block-mounting plates. The upper and lower portions of the block-mounting plates are folded frontward so as to form an upper reinforcing rim and a lower reinforcing rim. The right and left vertical side frames have an L-shaped horizontal cross section. The folded edges of the L-shaped right and left vertical side frames are arranged inward so as to face each other. The block-mounting plates have securing members along the left edge and the right edge thereof. The securing members project backward and have an L-shaped horizontal cross section. The folded edges of the L-shaped securing members are arranged inward so as to face each other. The depth of the L-shaped securing members which project behind the block-mounting plates is determined in accordance with the depth of the at least one block to be mounted on the block-mounting plates. The folded edge of each L-shaped securing member is secured to the folded edges of each L-shaped vertical side frame.
