Description

[Detailed explanation of the idea] This invention relates to a storage structure for mounting boards.

As a mounting board, various electrical components such as a wire are mounted on one surface of the board body, and terminals of the various electrical components are electrically connected on the other surface of the board body by soldering or the like. There are known devices that form a predetermined electrical circuit.

By the way, when the above-mentioned mounting board is stored in a storage case, conventionally, the mounting board is simply fixedly supported and stored in the storage case.

Therefore, in order to maintain and inspect all the mounted boards stored in the storage case, inspection doors must be installed on the front, rear, and sides of the storage case. The work efficiency is poor because you have to insert your hand into the limited space inside the storage case, and you also need to take up work space inside the storage case, which reduces the number of mounting boards that can be stored and makes it difficult to use the storage case. During installation, a work space must be secured outside the circumferential surface of the storage case for maintenance and inspection of the mounting board inside the storage case, resulting in a disadvantage that the installation space becomes large.

Also, in the past, the mounting board was removably stored in a storage case, but in this case, in order to perform maintenance and inspection of the mounting board, wiring work, etc., the mounting board had to be removed by removing screws. Since the inspection worker has to carry out the removal work, there are drawbacks such as an extremely heavy burden on the inspection worker and a large amount of time being spent on the removal work.

This idea was made in view of the above circumstances, and allows maintenance inspections and wiring work for all the mounted boards stored in the storage rack to be extremely easily performed outside the front of the storage rack, greatly improving work efficiency. To provide a mounting board storage structure capable of compactly storing a large number of mounting boards in a storage rack, and requiring a small installation space for the storage rack.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

1st. 1.2.3 in FIGS. 2 and 3 are front, center, and rear mounting boards each having a rectangular shape on the plane,
Various electrical components 4 such as relays are mounted on the front surfaces 1a, 2a, 3a, and the rear surfaces 1b, 2
Predetermined electrical circuits for the various electrical components 4 are formed on the terminals b and 3b using connection pins, jumper wires, etc., and a handle 5 is attached to the front surface 1a of the front mounting board 1.

The mounting boards 1, 2.3 and a holder 6, which will be described later, are arranged in the front-rear direction and their right side parts 1c, 2c, 3c, 5a adjacent to each other are hinged by a hinge 7. has been done.

Also, their mutually adjacent left side parts 1 d and 2
d, 3d, and 6b are separably connected by screws 8.

In this way, the mounting boards 1, 2.3 and the holder 6 are
This assembly 9 is stored in a storage section 11 of a storage rack 10 so as to be freely drawn out.

A guide rail 12 extending in the front-rear direction is provided on the lower surface of the storage section 11, and a guide rail 12 is provided on the lower surface of the storage section 11.
Guide receivers 2e, 3e, and 5c are provided on the lower surface of the holder 6 (see FIGS. 3 and 4).

Further, a stopper 13 is provided at the front portion of the lower surface of the storage portion 11 and comes into contact with the stopper receiver portion 6C of the holder 6, so as to prevent the assembly 9 from being removed. .

In addition, the mounting boards 2, 3 and the holder 6 have insertion holes 2f, 3f, 6 through which the electrical wiring 14 from each mounting board 1, 2.3 is inserted and guided to various electrical devices (not shown).
d is provided.

In this embodiment, three assemblies 9 are stored in the storage rack 10, and the mounting board 1 in front of each assemblage 9 includes the central and rear mounting boards 2, Electrical components (for example, switches, meters, etc.) for controlling and monitoring the electrical circuits 3 constituted are mounted, and when each assembly 9 is stored, the front surface of the storage rack 10 is It is designed to be the operation panel surface.

According to the above configuration, when performing maintenance and inspection of the mounting boards 1, 2.3, the handle 5 is first grasped and the assembly 9 is pulled out.

For example, when inspecting the rear surface 2b of the central mounting board 2, remove the screws 8 connecting the central and rear mounting boards 2 and 3, and then By rotating the front and center mounting boards 1 and 2 together via the hinge 7 between the center and rear mounting boards 2 and 3, the rear surface 2b of the center mounting board 2 is positioned forward. .

Therefore, the rear surface 2b of the central mounting board 2 can be inspected very easily from outside the front of the storage rack 10, and at the same time, the front surface 3a of the rear mounting board 3 can also be inspected very easily. can be done.

Similarly, by removing the screws 8 corresponding to the surface to be inspected of the mounting boards 1, 2.3 and then rotating and displacing the surface to be inspected forward, maintenance and inspection of the surface to be inspected is extremely easy. can be done.

After the maintenance and inspection work is completed, the mounting boards 1, 2.3 are stored by performing the reverse work to the above.

The electrical wiring 14 is inserted into the insertion hole 2e in a slack state in advance.
, 3e, and 6d, so that no tension is applied by pulling out the assembly 9 or rotating the mounting boards 1, 2.3.

Note that the number of the assembly 9 stored in the storage rack 10 and the number of hinges of the mounting boards in the assembly 9 are arbitrary, and when the assembly 9 is pulled out forward, the guide rail 12
The assembly 9 may be supported by being pulled forward.

It is also possible to construct the assembly 9 by alternately hingeing the left and right sides of each mounting board 1, 2.3.

As described above, according to this invention, a plurality of mounting boards are arranged in the front-rear direction, adjacent mounting boards are hinged at the sides, and these are stored in a storage rack so that they can be freely drawn out. When performing maintenance inspections and wiring work, simply pull out each mounting board as a unit and then rotate the mounting board at the appropriate hinge point, making it extremely easy to store one side and the other side of all the mounting boards in the storage rack. As a result, maintenance and inspection work, wiring work, etc. can be performed extremely easily in a bright area outside the front of the storage rack without the operator having to move much or being forced into a cramped posture. This greatly improves work efficiency.

In addition, since there is no need to take up work space inside the storage rack, a large number of mounting boards can be stored, and there is no need to provide a special inspection door on the storage rack. Since the work space only needs to be secured outside the front, the installation space can be small.

In addition, as the number of electrical components mounted on a mounting board increases, the number of hinges on the mounting board can be increased.
There is no need to simply make the mounting board a large board, and therefore many mounting boards can be stored compactly.
