Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is characterized in that a main wiring board for connecting a subscriber line such as a telephone to a telephone station device such as an exchange is mounted, and terminal boards for the subscriber and the exchange are mounted. The vertical frame mounted on the main wiring board.

[0002]

2. Description of the Related Art A conventional device arrangement of a central office building is as follows.
The main wiring board is installed on a dedicated frame, and a vertical frame mounting the terminal board for the subscriber and the terminal board for the exchange is installed at a different position from the main wiring board, and the main wiring board and the vertical frame are connected to a cable. Connection.

[0003]

However, since the place where the dedicated frame of the main wiring board is installed is far from the place where the vertical frame is installed, there has been a problem that the cable connecting them must be long. In addition, the length of the cable had to be changed according to the equipment arrangement in the station building.

[0004] For this reason, cable accommodating ability and workability are poor, and the construction work time of the current station is long. Furthermore, since it is necessary to secure a space for installing a dedicated frame for the main wiring board and a space for the vertical frame, there is a problem that the floor space must be widened.

[0005]

According to the present invention, a main wiring board having a plurality of subscriber-side connectors and a plurality of exchange-side connectors is mounted at the center, and a first terminal board is provided on one side. , A plurality of second terminal boards are provided on the other side, a cable on the subscriber side is connected to the first terminal board, and the first terminal board and the subscriber of the main wiring board are connected. And the connector on the exchange side of the main wiring board with the second connector.
Are connected by a cable, and the second terminal plate and the cable on the exchange side are connected to form a vertical frame mounted on a main wiring board.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view (1) showing an embodiment, FIG. 2 is an explanatory view (2) showing an embodiment, and FIG. 1 is an explanatory view (3) showing an embodiment. FIG. 1 is a view of the vertical frame mounted on the main wiring board according to the embodiment viewed from the back, FIG. 2 is a view of FIG. 1 viewed from above, and FIG. FIG.

In FIG. 1, reference numeral 1 denotes a vertical frame mounted on a main wiring board according to the embodiment. Reference numeral 2 denotes a main wiring board. More specifically, a small and lightweight automatic main wiring board (S type)
Main Distribute Frame, hereinafter abbreviated as S-MDF. ). Reference numeral 3 denotes a fixture for fixing the S-MDF 2. Reference numeral 4 denotes a cable rack for accommodating cables. Reference numerals 5, 5a denote subscriber side cables, ie, subscriber (primary) cables, and reference numerals 6, 6a denote exchange side cables, ie, exchange (tertiary) cables. Reference numeral 7 denotes an S-MDF connector, which includes a connector 7a on the exchange side and a connector 7b on the subscriber side. Reference numeral 8 denotes a cable support.

Reference numeral 9 denotes a first terminal board (H0), which is a subscriber side ARR (arrester: lightning arrester) terminal board. A plurality of the first terminal plates are provided, each having a pair of connectors 9a and 9b. Reference numeral 10 denotes a second terminal plate (V0), which functions as a terminal plate on the exchange side. A plurality of the second terminal plates are provided, each having a pair of connectors 10a and 10b. (Note that the terminal plate 9,
In order to distinguish 10, the first terminal plate 9 is indicated by a two-dot chain line,
The second terminal plate 10 is shown by a solid line. Reference numeral 11 denotes a mounting table for mounting the S-MDF.

The flow of wiring will be described below. A cable 5a from the subscriber side is drawn in from, for example, the upper right side in FIG.
And connect to the connector 9a on one side of the first terminal plate 9. Further, the other connector 9b of the first terminal plate 9
And the connector 7b on the subscriber side of the S-MDF are connected by a cable 5.

Then, the connector 7a on the exchange side of the S-MDF and the connector 10b on one side of the second terminal plate 10 are connected by the cable 6, and the other connector 10a of the second terminal plate 10 is connected to the exchange side. Connect to cable 6a.
As described above, the subscriber line is connected to the first terminal board 9 and the S-MDF.
The connection is made to the exchange via the second and second terminal boards 10.

As described above, the S-MDF 2 is disposed at the center, the first terminal plate 9 is disposed on the right side of FIG.
When the terminal board is disposed, the cable 5a on the subscriber side is pulled in from the upper right side of FIG. 1 and proceeds to the second terminal board 10 via the first terminal board 9 via the S-MDF 2;
The cables can flow to the exchange by the cables 6a on the exchange side, and the cables 5a, 5, 6, and 6a can be ideally wired. In other words, there is no extra cable fold or the like, the cable length is shortest, and the housing and routing of the cable are facilitated.

An S-MDF is provided in the vertical frame 1 on which the first terminal plate 9 and the second terminal plate 10 are mounted.
2, the dedicated S-MDF rack is not required, and the floor space can be significantly reduced. It goes without saying that the same function can be obtained even if all the left and right relationships in FIG. That is, without being limited to the above description, the S-MDF 2 is disposed at the center, the first terminal plate is disposed on one side, and the second terminal end is disposed on the other side. What is necessary is just to attach a cable corresponding to.

[0013]

As described in detail above, since the main wiring board is mounted in the vertical frame on which the terminal board is mounted, the installation space is reduced. In addition, the main wiring board is arranged in the center, the first terminal board is arranged on one side, and the second terminal end is arranged on the other side. This has the effect of improving the accommodating property and the workability.

Since the main wiring board and the first and second terminal boards are adjacent to each other, the cable length can be reduced. Further, there is an effect that cost can be reduced by improving workability and workability of the cable and shortening the cable length.
