    • 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.
    • 用于安装通信装置的机架。 机架包括一对左右垂直侧框架和多个块安装板,用于安装至少一个容纳至少一个印刷板的块。 块安装板是矩形的并纵向设置在左右垂直侧框架之间。 至少一个块安装在块安装板的前表面上。 块安装板的上部和下部向前折叠,以形成上加强边缘和下加强边缘。 右侧和左侧垂直侧框架具有L形水平横截面。 L形的左右垂直侧框架的折叠边缘彼此面对地布置。 块安装板具有沿着其左边缘和右边缘的固定构件。 固定件向后突出并具有L形横截面。 L形固定构件的折叠边缘彼此面对地布置。 根据要安装在块安装板上的至少一个块的深度来确定突出在块安装板后面的L形固定构件的深度。 每个L形固定构件的折叠边缘固定在每个L形垂直侧框架的折叠边缘上。

    • A mechanism for insertion and withdrawal of a printed board unit (20) to and from a shelf (10), by which the printed board is inserted in the shelf with less force and locked therein after the completion of the operation, an the complete insertion can be confirmed by a click noise and a mark. The mechanism includes a lock arm (26), which is fixed to the printed board unit (20) at the base portion thereof and has a flexible tip, a lever (25) pivoted to the printed board unit (20) and provided with a cam surface (30) for driving the lock arm (26) for insertion and withdrawal of the printed board unit (20), and an aperture (17) formed on the shelf (10) and engageable with the lock arm (26) when the same is in a fixed position. The lever (25) occupies predetermined angular positions, both when the printed board unit (20) is completely engaged to a connector and when the printed board unit is withdrawn therefrom.
