Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an auxiliary relay storage box, and particularly to an auxiliary relay storage box that can be partitioned at any position.

[Technical background of the invention]

Conventionally, auxiliary relays have been installed all together inside a storage box. FIG. 1a is a perspective view of a conventionally used horizontally arranged auxiliary relay storage box, FIG. 1b is a sectional view taken along line A-A' in FIG. 1a, and FIG. FIG. In FIG. 1a, 1 is a horizontally arranged auxiliary relay storage box, 2 is a collar, and is fixed to the switchboard 100 shown in FIG. 1c with screws 3. 4 is welded to the collar 2 with a nut to attach and fix the dustproof cover 5. 6 is a transparent glass so that the internal elements of the auxiliary relay storage box 1 can be confirmed. Reference numeral 7 designates a knob whose tip is a screw, and is used to attach the dustproof cover 5 to the nut 4 of the auxiliary relay storage box 1. As shown in FIG. 1b, 8 is a terminal block unit for transferring input/output signals of the auxiliary relay, and a reinforcing rod 9 connects the auxiliary relay storage box 1.
is fixed with screws. 10 is an auxiliary relay stored in an auxiliary relay storage box. An embodiment in which the auxiliary relay storage box constructed in this way is mounted on a box switchboard is shown in FIG. 1c. In FIG. 1c, W indicates the width of the distribution board to be regulated, and 1L indicates line 1 and 2L indicates line 2, which are divided according to purpose. Also, as a method of dividing, use the dashed double-dot line H
-H' as the center, 1L' for line 1, 2L' for line 2
It may also be used as a line.

[Problems with background technology]

In the conventional device having the above configuration, the width W of the switchboard 100 installed in the horizontally arranged auxiliary relay storage box is regulated, and the auxiliary relay storage box is designed to accommodate the maximum number of auxiliary relays. Not only is there not enough space for arbitrary partitioning, but the first
As shown in Figure c, for example, the upper two boxes are used for 1L (Line 1) and the lower two boxes are used for 2L (Line 2), so they are divided into boxes for each line. It was not possible to manufacture and wire each unit.
Also, recently, from an ergonomic point of view, it has become common to divide vertically according to use, and as shown in Figure 1c, the division is divided into 1L' and 2L' with H-H' at the center. However, it was unclear because there was no partition plate.
As a result of the above, maintenance and inspection are difficult, which not only hinders the diversification and multi-purpose use of the storage box, but also requires a large amount of man-hours for manufacturing and wiring.

[Purpose of invention]

The present invention has been made to solve the above problems, and aims to provide an auxiliary relay storage box in which auxiliary relay elements can be partitioned at arbitrary positions within the storage box.

[Summary of the idea]

In this invention, the required number of dustproof covers corresponding to each partition position of the unit storage box is prepared, the partition dimensions are determined, the partition plate is inserted at this position, and the partition plate is screwed through holes made on the side of the storage box. It is intended to be firmly fixed.

[Example of idea]

Examples will be described below with reference to the drawings. Fig. 2 is a configuration diagram of one embodiment of the auxiliary relay storage box according to the present invention, Fig. 2a is an overall perspective view showing the dustproof cover separated, and Fig. 2b is a line B-B in Fig. 2a. FIG.

In the figure, 1' is a vertical auxiliary relay storage box;
Reference numeral 11 denotes a collar for attaching the auxiliary relay storage box 1' to a power distribution board (not shown) with screws. Reference numeral 12 denotes a partition plate, which is inserted into a required position in the vertical auxiliary relay storage box 1' and fixed with screws through holes 13 made in the side surface of the storage box. Numeral 14 is a nut that is welded. Reference numerals 15, 16, and 17 denote dustproof covers, each having a size corresponding to the interval divided by the partition plate 12 inside the auxiliary relay storage box. Transparent glasses 15a, 16a, and 17a are provided on the front surface of the dustproof cover, and are used to confirm the auxiliary relay elements in the auxiliary relay storage box. And dustproof covers 15, 16, 17 are knobs 1
5b, 16b, and 17b are respectively fixed to nuts provided in the auxiliary relay storage box. The terminal block unit 8, the reinforcing rod 9, and the auxiliary relay 10 are the same as those shown in FIG. As shown in the partial cross-sectional view of FIG.
8 to tighten the top and bottom, respectively, to maintain strength. In addition, FIG. 3 is a perspective view of the auxiliary relay storage box of the present invention installed on the power distribution board 200, and is 1L.
(Line 1) and 2L (Line 2) each have storage boxes, 1
It shows that the box is clearly divided vertically and can be subdivided into 1L or 2L.

Therefore, when in use, the auxiliary relay elements are stored in each compartment according to their purpose, and during maintenance and inspection, the dust cover of the required compartment can be removed to perform work within the required compartment.

[Effect of idea]

As explained above, according to the present invention, since the partition plates are provided at arbitrary positions and the dustproof covers are provided corresponding to the partition sections, the unit storage box can be divided into arbitrary numbers according to the number of auxiliary relays. In addition to being versatile and multipurpose, it is also possible to assemble each line and divide the wiring, which has the advantage of reducing man-hours and shortening the construction period.
