Description

[Detailed explanation of the invention] [Background of the invention] This invention reduces the length of the control cable that connects a switchboard and a switchboard or a switchboard and an electrical device, and increases the number of cores of the control cable in order to reduce construction costs. This invention relates to improvements in relay terminals used to reduce the number of wires, so-called multi-core.

[Prior art]

At a substation, the control cables that connect each device installed in the substation and the switchboard for controlling the substation run like a mesh between each device and between the switchboard and the devices. However, it has been known for some time that it is economical to communicate this using one or several multi-core cables. In this case, it is necessary to prepare a relay terminal block for connecting small-core control cables pulled out from each device terminal to multi-core cables.

The conventional relay terminal board has a box body 1 as shown in Figure 1.
It consists of a floor plate 5 and a roof 4 of a base 6 with doors 2 on the front and rear sides. Inside, a terminal block 8 for relaying a lead-in cable 9 and a lead-out cable 10 is attached to the box body 1 through a mounting bracket 11. As shown in FIG.
8B, 8C, 8D, 8E, 8F, 8G, 8H are arranged, and the lead-in cables 9A, 9B, 9
C and the lead-out cables 10A and 10B were also normally arranged linearly and alternately on both sides of the terminal block 8. In a substation, these terminal blocks 8 are usually arranged in six or eight rows. In this case, if a straight line arrangement is performed, the width L of the relay terminal box 1 will increase, and the connection work of the lead-in cables 9A to 9C and the lead-out cables 10A and 10B will be alternated, resulting in a lot of connection work and inconvenience. Ta.

FIG. 3 shows a structure in which four terminal blocks 8A to 8D are arranged at predetermined intervals. According to this structure, the above-mentioned drawbacks can be eliminated, but there is a drawback that the width dimension is large and the relay terminal becomes large.

[Purpose of invention]

An object of the present invention is to provide a relay terminal board that is compact and easy to connect.

[Summary of the idea]

The relay terminal board of the present invention has at least a pair of mounting brackets each having an inclined surface on both ends, a terminal block is attached to the inclined surface, and one end of the terminal of the terminal block is connected to a lead-in cable arranged between the inclined surfaces. The above-mentioned object is achieved by comprising a pull-out cable arranged between the mounting brackets.

[Example of idea]

Embodiments of the present invention will be described below with reference to FIGS. 4 and 5.

A rectangular support member 20 is installed on the floor,
The pull-out cable 10 is arranged inside, and the support member 20
Mounting brackets 11A and 11B are attached to four locations on the outside of the frame. Both ends of each mounting bracket 11A, 11B are
An inclined surface 12 is formed. Each slope has relay terminal blocks 8A, 8B, 8C, 8D, 8E, 8F, 8
G and 8H are installed. One relay terminal 8A,
One end of 8E, 8D, 8H is connected to the lead-in cable 9
A and 9C, and the other end is connected to the pull-out cable 10, respectively. The other relay terminal 8B, 8F
And one end of 8C, 8G is attached to the lead-in cable 9B,
The other ends are connected to the pull-out cables 10, respectively.

In addition, in the above embodiment, four mounting brackets were used, but it is possible to increase the number to eight or twelve, for example, and furthermore, as shown in FIG.
Two pieces A and 11B may be arranged. In this case, each mounting fitting 11A, 11B is attached to a support member, although not shown.

According to this configuration, as shown in FIG. 5, the lead-in cables 9A, 9B can be disposed between the one side slope 12A and the other side slope 12B, and the pull-out cable 10 can also be arranged between the lead-in cables 9A, 9B. Because they can be arranged almost correspondingly, the width dimension is smaller than when the terminal blocks are arranged on the same plane as in the conventional relay terminal board shown in FIGS. 2 and 3.
The relay terminal board width dimension L can be reduced, and the work efficiency is improved because the worker does not have to move much to perform the connection work.

[Effect of idea]

As described above, according to the relay terminal board of the present invention,
It is small and can facilitate connection work.

Claims (1)

[Scope of utility model registration request] A relay terminal block is attached to a mounting bracket, and each terminal attached to both ends of the relay terminal block is connected to a drop-in cable and a pull-out cable. Place the metal fitting and the other mounting metal so that the sloped surfaces expand outward, attach a relay terminal block to each slope, and connect the terminals provided at both ends of the relay terminal block to the incoming cable and the outgoing cable. However, it is recommended that the lead-out cable be placed between one mounting bracket and the other mounting bracket, and the lead-in cable be placed between one sloped surface and the other sloped surface so as to correspond to the lead-out cable. Features a relay terminal board.
