Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring board used as an auxiliary equipment such as a switchboard for connecting an outside line side and an inside side of a station.

[0002]

2. Description of the Related Art FIG. 2 is a perspective view showing a conventional wiring board, which is a vertical bar 11 having a frame structure for mounting a connector block 12 for accommodating a subscriber cable on the outside line side.
And a horizontal bar 13 having a skeleton structure for mounting a terminal board 14 for accommodating an intra-station cable on the exchange side, and a cross bar 17 connecting the vertical bar 11 and the horizontal bar 13. In this conventional wiring board, not only is it fixed to the floor surface by anchor bolts at the time of installation, but also the wiring board is tilted from the ceiling (not shown) by using hanging bolts 15 and hanging angles 16 as shown in FIG. It is fixed so that it does not exist. Further, the jumper work on the wiring board is performed so as to connect between the connector block 12 on the vertical side and the terminal board 14 on the horizontal side, that is, across the front and back surfaces of the wiring board.

[0003]

This conventional wiring board is
As described above, the frame structure is used, the number of parts is very large, and a large number of man-hours are required for the assembling work. Also, since the jumper that connects the subscriber cable side and the in-station cable side is divided into the front and back sides of the vertical side and the horizontal side, it becomes difficult to perform as the size of the exchange increases, and the maintenance man-hour increases. There was a point.

[0004]

The wiring board of the present invention has a mounting hole for fixing it to the floor on the bottom surface and mounts a plurality of connector blocks for accommodating the subscriber cable on the outside line in one terminal. A vertical frame having a frame structure for connecting the plurality of first terminal plates having the mounting holes at the bottom and accommodating the intra-station cables on the exchange side, and the other terminals of the connector block by the connector cables. And a horizontal frame having a frame structure for mounting a plurality of second terminal boards; a first support connecting the vertical frame and an upper part of the horizontal frame, and a second frame connecting the lower part. A support; a structure having a structure in which the support holes are fixed to the floor surface of the installation site to be self-supporting, and the first and second terminal plates are connected between the front surface sides of these terminal plates. Performing the damper connection being arranged to allow a configuration having a predetermined space for the work between the vertical rack frame which are connected by the support and the Horizontal rack frame.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a wiring board showing an embodiment of the present invention. The present wiring board of the present invention has a mounting hole (not shown) for fixing it to the floor on the bottom surface thereof, and for mounting a plurality of connector blocks 2 for accommodating the outside subscriber cable 6 in one terminal. The vertical frame 1 having a frame structure, and a plurality of terminal boards A4 having mounting holes (not shown) in the bottom and accommodating the intra-station cable 7 on the exchange side.
And a horizontal frame 3 having a frame structure for mounting the other terminal of the connector block 2 and a plurality of terminal boards B5 connected by a connector cable, and the vertical frame 1 and the upper parts of the horizontal frame 3 are connected to each other. Upper support 9
And a lower support 10 that connects the lower parts to each other.

In FIG. 1, a vertical frame 1 is provided with a maximum of 13 connector blocks 2 for accommodating subscriber cables 6 in units of 100 pairs in a vertical direction, and five rows form one basic form. The connector block 2 includes a lightning arrester for each line.

On the horizontal frame 3, 96 pairs or 1 of the intra-station cables 7 from the exchange are arranged in four rows on the right side when viewed from the front.
With 28 pairs as a unit, a maximum of 9 terminal boards A4 are mounted in one row in the vertical direction, and a total of 36 terminal boards A4 are mounted in four rows. In the left half of the five rows, 100 pairs of terminal boards B5 facing the connector block 2 mounted on the vertical side are mounted in one row in the vertical direction, and a maximum of five rows is used as a basic configuration.

A 500 mm working space determined by an upper support 9 and a support 10 described below is provided between the vertical frame 1 and the horizontal frame 3, and the subscriber cable 6 is connected to one side of the connector block 2 from the rear surface of the connector block 2. Wire to the terminal. Similarly, the intra-station cable 7 is also connected to the terminal board A4 from the rear surface. Further, the connector block 2 and the terminal board B5 are connected between the rear surfaces by a cable which has been made into a connector in advance. The jumper 8 connects the terminal plate A4 and the terminal plate B5 in a plane, and the subscriber cable 6 and the exchange side are arbitrarily connected.

The upper support 9 and the lower support 10 connect between the vertical frame 1 and the horizontal frame 3,
Each frame is supported so that it will not fall over, and this wiring board has a structure in which it is fixed by anchor bolts to the floor surface of the installation site using the mounting holes in each frame to make it self-supporting.

[0011]

As described above, according to the present invention, the vertical frame and the horizontal frame are connected to each other by the support and fixed to the floor so that they are self-supporting, and the ceiling or the support from the wall is unnecessary. The construction material can be reduced. Also, by changing the wiring board from a frame structure to a frame structure, the crossbar of the conventional wiring board is greatly reduced, the field assembly work is simplified, and the subscriber cable on the outside line and the exchange side are connected. The jumper work becomes a single-sided jumper only on the horizontal side, and the jumper man-hour is reduced to half of the conventional one, which is effective in shortening the construction period.
