Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switchboard device, and more particularly to a switchboard device that can easily connect and process the wiring of appliances.

The switchboard and control panel are equipped with many types of instruments and instruments.

The connections of these meters and instruments to external connection terminals or to each other are very complex.

For example, in a closed switchboard, built-in equipment such as circuit breakers and disconnectors must be housed inside, and electrical equipment such as relays and fuses necessary for controlling these built-in equipment and various electrical interlocks must be installed on the door. Additionally, wiring must be done between the electrical appliance and the built-in equipment.

FIG. 1 shows the conventional wiring state, and the figure is an enlarged view of the back side of the door, showing the state of wiring to electrical appliances.

In FIG. 1, the wires extending from the built-in equipment (not shown) are gathered together to form a bundled wiring 2a, and
and is fixed by a bind 4 at an appropriate position.

A relay terminal block 5 is provided at the end of the device mounting plate 3, and each wire 2a1, 2a2...2aN is separated from the bundled wiring 2a and connected to the relay terminal block 5 one by one. .

From this connected relay terminal block 5 on the opposite side, relay A,
Each line 2b1, 2b2...2bN is connected to B, C, D.

Each line 2b1, 2b2 extending from this relay terminal block 5...
...2bN are put together again to form bundle wiring 2b, and in order to wire to each relay A, B, C, D, arrows 0, P,
The bundled wiring 2b is divided into three parts in the Q direction.

These wire bundles 2b extending in the 0, P, and Q directions are connected to each relay A.
, B, C, and D from the top and bottom.

For example, upper terminals A1, A2, A3, A4 of relay A
, A5, connect terminals A1 and A2 in advance.
, A3, A4, A5, the length of the other four wires is matched to the length of the final end A5 to form a bundled wire 2b, and in the final assembly process, wires are attached to each terminal A1, A2, A3, A4, A5, respectively. Match the lengths, process the terminals, provide a connection terminal at the tip, and connect relay A.
It is connected to each connection terminal of.

The other relays B, C, and D are also the same as described above.

Wiring between the connection terminals of each relay A, B, C, and D and the relay terminal block 5 is fixed by a bind 4 and arranged regularly.

The reason for arranging the wiring regularly in this way is that when the door is opened, all the wiring on the back side can be seen, so the appearance must be considered.

For example, if the wiring is messy, it can get caught on other devices and break, or the connection terminals can come off, making it even more unsightly.

However, for this reason, it takes a lot of time to lengthen and shorten the wires, and to fix the wires with the binder 4, which is extremely inefficient.

An object of the present invention is to provide a switchboard device that reduces wiring work time.

The switchboard device of the present invention forms a space between the back side of a front mounting plate of a switchboard that houses built-in equipment and an appliance mounting plate that has various electrical appliances that control the built-in equipment, and in this space, The purpose is to store and adjust the wiring from the built-in equipment to the electric appliance, and to make wiring easier by forming wire entry/exit holes in the appliance mounting plate.

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

The embodiments of FIGS. 2-5 show surface mounting surfaces for closed distribution boards.

In the figure, a U-shaped instrument mounting plate 3' is fixed to the back surface 1 of the front surface mounting plate of the door with screws 1A, and a space R is formed between the back surface 1 and the instrument mounting plate 3'.

To form the space R, a support member 7 may be provided between the back surface 1 and the instrument mounting plate 3' as shown in FIG.

The space R should be large enough to accommodate each wiring.

On the equipment mounting plate 3', electrical equipment such as protective equipment 8, auxiliary equipment 6, relay terminal block 5, etc. necessary for controlling built-in equipment such as relays and circuit breakers in the power distribution board such as fuses, and various interlocks are arranged. In addition, wire entry/exit holes 3'a, 3'b, 3' are provided at appropriate locations on the equipment mounting plate 3' to facilitate wiring to the protective equipment 8, auxiliary equipment 6, relay terminal block 5, etc.
c and 3'd are opened and penetrate through the above-mentioned space R.

The wire entry/exit hole is provided in the same plane as the appliance mounting plate 3' on which the electric appliance is disposed, and is formed into an elongated shape that allows a plurality of wires to move relative to each other.

When wiring each of the above-mentioned appliances, as shown in Fig. 4, the wires extending from the built-in equipment are gathered together to form a bundled wiring 9a, fixed to the back surface 1 with a bind 4 at an appropriate position, and the wires extended from the built-in equipment are bundled together to form a bundled wiring 9a. The cables are separated one by one, guided to the device mounting plate 3', and connected to the relay terminal block 5 one by one.

Each wire 9a1 from the relay terminal block 5 on the opposite side of the connection
, 9a2...9aN extend, pass through the space R from the wire entry/exit hole 3'a, and connect to the protective device 8 and the auxiliary device 6 via the wire entry/exit holes 3'b, 3'c, and 3'd. It is something.

In this way, the length of each wire extending from the relay terminal block 5 to each protective device 8 and auxiliary device 6 can be adjusted to the longest end of the terminal of each device, and the length of the terminal of each device can be adjusted in a space. This can be easily done by simply leaving some slack in R.

Furthermore, it is possible to connect the connecting terminals at the tips of each wire by determining the length of the wire from the beginning and then connecting the connecting terminals in advance.

Since all the wires are routed through the back side of the device mounting plate 3', there is no need to consider the fixing and placement of the wires, and even when the back side 1 is open, the wiring can be routed through the device mounting plate 3'. It is hidden behind 3' and cannot be seen, just the neat connections of the terminals are visible, giving it a very nice appearance.

In addition, on the equipment mounting plate 3' on which electrical equipment such as the auxiliary equipment 6 and the protective equipment 8 are arranged, there are wires 9a1 and 9a that penetrate the space R.
2...9aN line entry/exit hole 3'a, 3
'b, 3'c, and 3'd have been provided, making wiring work easier.

For example, the protective device 8 has wires 9al and 9a2 on the upper terminal side.
Since the wires on the lower terminal side are connected to the terminals of the relay terminal block 5 from the space R through the entry/exit hole 3'b, there are few exposed wires on the surface of the appliance mounting plate 3'. Not only does it look good, but if there is no wire entry/exit hole 3'b, the wires on the lower terminal side can be wired at the upper and lower ends of the equipment mounting plate 3' or on the surface of the equipment mounting plate at the left and right ends. Therefore, there is no point in creating a space, and in order to perform regular wiring, bands are used for wiring or bundled wiring is performed, which makes wiring work difficult. However, the present invention Now, wiring work is easier because you only have to store the wires in the space rather than the inlet/outlet hole.

This will be explained in more detail.

In other words, when connecting between a built-in device and an electric appliance, after storing multiple wires from the built-in device in a space, these wires are pulled out from the wire entry/exit hole, and the wiring are hanging down to make wiring easier.

After any of the hanging wires is moved through the elongated wire entry/exit hole and connected to any electrical appliance or terminal, the hanging wire is stored in the space from the wire entry/exit hole.

In addition, when wiring a crossover between one electrical appliance and another electrical appliance that is separated from it, the crossover wiring can be moved within the elongated wire entry/exit hole, and the crossover wiring can be inserted into the space after connection. Easy to work with.

In this way, a plurality of wires can be moved within the elongated wire entry/exit hole, and the wires after connection can be easily stored in the space, so wiring work can be easily performed without any restrictions.

On the other hand, if the wire entry/exit hole is formed on the same plane as the equipment mounting plate on which the electrical equipment is installed, the worker can work while looking at the same plane, so he or she can move his or her head up, down, left or right, or turn his/her eyes. It is easy to work because there is no need to move the focus of the workpiece or take an unreasonable working posture.

However, it is not necessary to provide the relay terminal block 5 on the appliance mounting plate 3', and the wires separated from the bundled wiring 2a are directly guided into the space R through the wire entry/exit hole 3'a and wired to each appliance. be able to.

As in the above-described switchboard device of the present invention, a space is formed between the back surface of the surface mounting plate and the appliance mounting plate, and the wiring is adjusted within this space to connect and wire each electric appliance, thereby allowing the installation of electric appliances. Even if the positions are different, all the lines can be used with the same length, which improves work efficiency.

Since each wiring still runs through the space, even if the door is opened, these wirings are not visible, making it possible to obtain a switchboard device with a simple structure and a very good appearance.

Furthermore, we have provided a wire entry/exit hole that penetrates into the space on the equipment mounting plate on which the electrical equipment is installed, so that the wires going in and out of the electrical equipment can be stored in the space immediately from the wire entry/exit hole, making wiring work easier. It is easy to install and has a good appearance with less exposed wiring.
