BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board used in, for example, collective stores and offices.

[0002]

2. Description of the Related Art Conventional examples (for example, Japanese Utility Model Publication No. 56-120627)
Is shown in FIG. That is, this conventional example is a distribution board for a single-phase three-wire, and includes a voltage line bar 70 and a neutral line bar 71 which are wired in parallel, and is arranged along both sides of the voltage line bar 70 along the voltage line bar 70. It is provided with a plurality of branch breakers 74 provided and a plurality of neutral switches 75 arranged in parallel in a direction orthogonal to the branch breakers 74 at the end of the neutral wire bar 71. A load 80 such as a computer is connected to the load terminal 73 of the branch breaker 74 and the load terminal of the neutral switch 75. 72 is a power supply terminal of the branch breaker 74, 78 is a main breaker, 79 is a power supply, and 81 is a load 80.
And a branch breaker 74 and a neutral switch 75.

[0003]

However, this distribution board has a branch breaker 74 and a neutral switch 75.
Are separated from each other, the length of the core wire when the outer jacket of the cable 81 is peeled off is different, which makes the peeling work complicated and the correspondence between the terminal of the load 80 and the branch breaker 74 is difficult to understand. Since the connection becomes complicated,
Therefore, there is a drawback that the wiring work becomes troublesome.

Therefore, an object of the present invention is to provide a distribution board which can facilitate wiring work.

[0005]

According to the distribution board of the present invention, a voltage line bar is arranged in the center, and a plurality of branch breakers are arranged in parallel along at least one side of the voltage line bar along the voltage line bar. Along with, the neutral line bar is arranged in parallel to the voltage line bar on the side opposite to the voltage line bar of the branch breaker,
This neutral line bar is equipped with a plurality of neutral switches.

[0006]

According to the construction of the present invention, since the neutral wire bar is provided on the load side of the branch breaker and the neutral switch is provided on the load side, the load side of the branch breaker and the neutral switch approach each other. Wiring work can be facilitated because wiring can be shortened, misconnection can be prevented, and load wires can be easily connected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. That is, in this distribution board, as shown in FIG. 1, the voltage line bar 2 is arranged in the center, and a plurality of branch breakers 3, 3 ′ are arranged on both sides of the voltage line bar 2, and the branch breakers 3, 3 ′ are arranged. A neutral wire bar 4, 4'on the side opposite to the voltage wire bar 2 of 3 '
And neutral switches 5 and 5'are mounted on the neutral wire bars 4 and 4 '.

The pair of voltage line bars 2 and 2'are arranged in parallel with connecting portions 2a, 2b, 2a 'and 2b' at both ends thereof. The plurality of branch breakers 3, 3'are arranged in parallel along the voltage line bars 2, 2'on both sides of the pair of voltage line bars 2, 2 ', and the power supply side terminals () of the branch breakers 3, 3' ( (Not shown) is connected to the pair of voltage line bars 2 and 2'via a connecting fitting 7 by screws.

The neutral wire bars 4 and 4'are provided with connecting portions 4 at both ends.
a, 4b, 4a ', 4b' are arranged parallel to the pair of voltage line bars 2, 2'on both outer sides of the plurality of branch breakers 3, 3 '. The neutral wire bars 4 and 4'are connected to the neutral wire relay bar 1 through the transition bars 6 and 6 '. The neutral wire relay bar 1 is arranged between the pair of voltage line bars 2 and 2'in parallel with them, and has connection portions 1a and 1b at both ends thereof.
Have. One end of each of the transition bars 6 and 6'is connected to the connection portion 1b by a screw, and the other end thereof is a connection portion 4 of the neutral wire bar 4 and 4 '.
It is connected to b and 4b 'by screws.

A plurality of neutral switches 5, 5 '
Are provided on and electrically connected to the neutral conductor bars 4, 4 '. In this embodiment, a pair of inner unit units U configured as described above are arranged in parallel. 8,9,9 ', 1
0 and 10 'are neutral line relay bars 1, a pair of voltage line bars 2,
It is a transition bar connecting the 2'and the neutral wire bars 4, 4 '.

Further, as shown in FIG. 2, the neutral line relay bar 1, the pair of voltage line bars 2 and 2 ', and the branch breakers 3 and 3'are attached to a mounting plate 13, and the mounting plate 13 is mounted. It is attached to the legs 12, 12 '. Further, neutral wire bars 4, 4'provided with neutral switches 5, 5'are attached to the attachment legs 11, 11 '.
For connection with a load line (not shown) connected to a load (not shown), one line of the load line is connected to a load side connection terminal (not shown) of the branch breaker 3, 3 ', and the other line is neutral. This is done by connecting to switches 5 and 5 '. Then, the connection portion 1 of each of the neutral line bar 1 and the pair of voltage line bars 2 and 2 '.
a, 2a, 2a 'are connected to a main breaker (not shown) via one integrated watt hour meter (not shown).

FIG. 3 shows the outer shape of the distribution board, in which the breaker panel 20 is opened and the internal unit U is housed inside. Reference numeral 21 denotes a meter panel to which the integrated electric energy meter 22 is attached. The distribution board of this embodiment is
Branch switches 3, 3'with neutral switches 5, 5 '
Since it is arranged in the vicinity of the load side terminal, it is possible to shorten the routing of the load wire and prevent misconnection.

Although the branch breakers 4 and 4'in the embodiment are arranged on both sides of the voltage line bars 2 and 2 ', they may be arranged on at least one of the voltage line bars 2 and 2'.

[0014]

The distribution board of the present invention has the neutral line bar on the load side of the branch breaker and the neutral switch provided on it, so that the load side of the branch breaker and the neutral switch approach each other. There is an effect that wiring of the wire can be shortened, erroneous connection can be prevented, connection of the load wire is facilitated, and wiring work is facilitated.
