Description

[Detailed Description of the Invention] The present invention relates to a power distribution board that is located between telecommunications equipment, particularly various types of transport equipment, and is used to facilitate the operation and maintenance of communication lines. be.

In general, this type of power distribution equipment is not only low-cost, but also easy to use during construction work, initial power distribution work, and when a line failure occurs.
It is required that it be easy to change the power distribution circuit when adding lines, and that it occupies a small space.

As a conventional device that satisfies these requirements, sockets for cables with electrical sockets 2 are attached during construction work to an electrical socket holding plate 1 having rows of holes for mounting electrical sockets 8 as shown in Fig. 1. During power distribution work, there is an example of a power distribution board 5 in which rows of electric sockets are all connected by cables 3 with electric plugs.

In this example, the initial power distribution work is easy because the connection is made using cable 3 with plug 9. At that time, by using cable 3 with plug with extra length, it is possible to change the power distribution circuit in case of line failure. In such cases, only the cable 3 with a plug needs to be replaced, and during construction, a distribution rack 6 composed of a frame frame 4 and an electric socket holding plate 1 may be installed, and the cable 3 with an electric plug and Both of the cables with electric sockets 2 can be manufactured in a factory, so that manufacturing efficiency can be easily improved, and they have many economical advantages and are put into practical use.

However, as transport equipment becomes smaller and the line capacity per unit space increases, the amount of power distribution equipment and the cables that connect them are also increasing.Nowadays, there is a need for small power distribution equipment that can accommodate these transport equipment. It is becoming.

In order to realize a compact power distribution device with a large capacity per unit space in the conventional structure, one method is to use a frame made of a material and shape with greater strength/volume, and another method is to use a small cable, There are ways to use plugs and sockets, but with the former, we cannot expect a significant improvement because the cables and switchboards are heavier due to the larger capacity.

Furthermore, even if it were implemented, it would be uneconomical due to the use of expensive materials.

On the other hand, the latter method has problems such as not being easy to implement in order to maintain a predetermined line quality.

An object of the present invention is to provide a power distribution board for telecommunications equipment that can economically construct a power distribution device with a large capacity per unit space.

The present invention constructs an arbitrary power distribution circuit by arranging a group of multiple electric sockets in one row and connecting the electric sockets of two or more rows of power distribution boards with conductors with electric plugs that fit into the electric sockets. A power distribution board for telecommunications equipment, characterized in that adjacent opposing sockets are connected by U-shaped plugs without cables, and sockets that do not face each other are connected by cables with electrical plugs to construct any power distribution circuit. This is a power distribution board for telecommunications equipment.

The present invention will be explained in more detail below with reference to the embodiment shown in FIG.

In FIG. 2 showing the switchboard of this embodiment, 1' is an electric socket holding plate having holes into which electric sockets 8 can be installed in two rows, and the distance between the rows is such that two plugs 9 can be connected electrically without cables. The distance between the plugs is set to be the same as the distance between the U-shaped plugs 7 connected to the U-shaped plugs 7.

This electric socket holding plate 1' is mechanically fixed to one rack frame 4 having a U-shaped cross section with screw elements. In order to make an electrical connection between the various conveying individual devices along the cable, the socketed cable 2 is first fitted with an electrical socket 8, which has a socket 8 at the end of the cable.

Next, the U-shaped plug 7 and the cable 3 with the electric plug are inserted into the electric socket 8 to form a predetermined power distribution circuit and a power distribution board is constructed.

If you wish to change the circuit of the switchboard configured as described above due to a failure in the communication line or the addition of a line, you can easily change it by replacing the cable with plug 3 or the U-shaped plug 7, and also use the electric socket holding plate. The installation work of the power distribution rack constructed by attaching the power distribution rack 1' to the rack frame 4 can be easily carried out in the same way as in the conventional example.

Communication equipment switchboards are originally used to improve the efficiency of operation and maintenance of communication systems, as mentioned above.
The simpler the power distribution circuit is, the more desirable it is, and the initial power distribution circuit is U
In most cases, only the plug 7 can be inserted.

Circuit change per failure requires several cables with electrical plugs3
However, if these connections gradually accumulate and become complicated and cross-connected to the point where they become a problem in terms of maintenance, it is possible to rebuild the circuit into a simple circuit that uses many U-shaped plugs.

Furthermore, even when circuits are changed during expansion, the U-shaped plug is almost never needed because the circuit structure is organized to be as simple as possible in terms of maintenance, including complex circuits that have been changed due to previous failures.

Since the space occupied by a single U-shaped plug is smaller than that of a cable with a plug, a switchboard configured with U-shaped plugs can not only construct a power distribution device with a larger capacity per unit space, but also use U-shaped plugs. The number of cables with plugs is reduced by the number of plugs, making it easier to understand the connection status and making replacement work easier.

Furthermore, since this U-shaped plug is constructed without a cable, it is easy to assemble and is economical because it can be manufactured at a much lower cost than a cable with a plug.

It also becomes possible to monitor lines at the switchboard.

In addition to the embodiments detailed above, various modifications can be made within the scope of the present invention.

For example, in this embodiment, there are two rows of socket rows, but three or more rows may be used, and U-shaped plugs are used to connect between the rows, but the distance between the socket mounting holes in the row is the distance between the plugs of the U-shaped plugs. It goes without saying that if it is the same as , it can also be used to connect between sockets in a row.

Furthermore, it is easily possible to attach a line indicator to the socket holding plate and add a locking mechanism to prevent the cable with a plug from being accidentally pulled out, making it possible to make the switchboard even more practical.

As is clear from the above explanation, the power distribution board for communication equipment according to the present invention is easy to perform construction work, initial power distribution work, and circuit modification work, and can construct a power distribution device with a large capacity per unit space, and is economical. It is also a target.

That is, the various advantages of the conventional example shown in FIG. 1 are hardly lost, and the disadvantages are eliminated, making it still economical and practical.
