BOARD FOR MAIN DISTRIBUTING BOARD

PURPOSE:To obtain unification of a distributing board structure and internal wiring by a wiring base plate with insulatorbility and to decrease assembling man-hours by installing wire rings for out-station cable and jumper wire-straightening at the fitting frame of a board for a distributing board. CONSTITUTION:A terminal block group 3A for accommodating an out-station in the first board assembled body 1 and a terminal block group 3B for a jumper are installed. Internal wiring between these terminal blocks is executed regularly. Next, another jumper terminal block group 3C, which connects a subscriber and an electronic exchange, and a receptacle group 4 which receives a protector module to protect in-station equipment from abnormal voltages or currents are installed. Respective out-station cables and jumper wires are accommodated and straightened by wire-straightening rings 9a and 9b, and these wire-straightening rings 9a and 9b are fixed securely at the lower-end part of the panel surface of an installing frame 6.
