Description

[Detailed Description of the Invention] The present invention relates to a cable bracket attachment device for supporting cables and the like.

Cable brackets are used as parts of electrical equipment such as transformers and switchboards, and are also widely used in electrical work to protect the terminals of electrical equipment and relay cables. etc. directly or via a seat.

In this case, it is necessary to create a mounting bolt hole or weld the mounting seat at the cable bracket mounting position, but it is extremely troublesome to drill holes with square pressure or weld them according to different specifications, and unnecessary manufacturing is required. Not only does this cost money and production time, but when changing the size of the cable bracket, the number of cable brackets to be installed, or the mounting pinch due to equipment changes at a later date, new holes must be drilled and welded from the beginning, making equipment changes necessary. Therefore, in view of the above-mentioned drawbacks, the present invention aims to provide a cable bracket mounting device that allows cable brackets to be installed very easily even if there are differences in specifications and changes in equipment. It was devised based on a new idea.

In order to achieve this purpose, the present invention has a long hole in the center of the U-shaped bent plate, excluding both bent shafts, to which a cable bracket can be attached along the longitudinal direction. On the other hand, a long hole or bolt hole drilled in a plate-shaped support fitting corresponding to each of the above two shaft parts,
Inserting and tightening a bolt so as to pass through the bolt hole or long hole drilled in both of the shaft parts, or through the long holes drilled in the support metal fitting and both the shaft parts,
It is characterized in that the support fitting and the shaft portion are fastened to each other at any position.

An embodiment of the present invention will now be described with reference to FIGS. 1a, l) and 2 a, l).

Figure 1a. In b, the plate bent in a U-shape has both bent shaft portions 1a and a central portion 1b excluding the shaft portions 1a.
One elongated hole 1c is formed in the central portion 1b along the longitudinal direction, and one elongated hole 1d is formed in both shaft portions 1a along the longitudinal direction.

This shaft portion 1a, central portion 1b1 and long hole 1c. A plate-shaped support fitting 2 is formed corresponding to the shaft portions 1a of both of the Plaquent mounting seats 10 formed by 1d.
Similarly to a, one elongated hole 2a is drilled along the longitudinal direction, and both longitudinal ends of the support fitting 2 are bent outward to form a welding margin 2b.

The support fittings 2 are welded to the side wall of the transformer terminal box, the side wall inside the switchboard, etc. at intervals corresponding to the width of the bracket mounting seat 10, that is, the length of the central portion 1b, and the shaft portion 1a of the bracket mounting seat 1 is attached to the support metal fitting. 2, and the long hole 1d and the long hole 2
A bolt is placed through the hole a to fasten the shaft portion 1a and the support fitting 2.

As a result, by loosening the bolt, the bracket mounting seat 1 can be moved back and forth along the elongated holes 2a of the support fittings 2 arranged in parallel.

In addition, the cable bracket 3 can be fixed to the bracket mounting seat 1 with bolts by aligning the bolt hole 3a of the cable bracket 3 shown in FIG. , the position of the cable bracket 3 can be changed in the longitudinal direction by the elongated hole 1c.

In this way, the cable bracket 3 can be moved in the width direction and the front-back direction, and the position of the cable bracket 3 can be freely changed in the same plane space.

The number of cable brackets 3 attached to the housing can be freely increased or decreased, and the size and device pinch can also be arbitrarily selected.

In Fig. 2a, two long holes 2c and 2d are bored in the plate-shaped support fitting 2 in the longitudinal direction so that the bracket mounting seat 1, which is a U-shaped plate, can be moved in the vertical direction. A welding margin 2e is provided at the end of the plate along the longitudinal direction, and the long holes 2c and 2d of the support metal fitting 2 are orthogonal to the long hole 1d of the shaft portion 1a, that is, the support metal fitting 2 is planted.

The bracket mounting seat 1 can be interposed between the supporting metal fittings 2 and fixed with bolts, and the bracket mounting seat 1 can be moved along the longitudinal direction of the supporting metal fitting 2, that is, the vertical direction.

Further, the bracket mounting seat 1 can also be moved in the front-rear direction by the length of the elongated hole 1d of the shaft portion 1a.

The cable bracket 3 shown in FIG. 2 is attached to the bracket mounting seat 1 through the elongated hole 1c of the central portion 1b, as in the case of FIG. 1.

The bracket mounting seat 1 can be installed in multiple stages vertically on the support fitting 2, and a large number of cable brackets 3 can be used.

In this way, the cable bracket 3 can be moved in the width direction and the vertical direction, and the position of the cable bracket 3 can be freely changed, especially in the vertical direction.

Although the above description is based on two embodiments, the present invention can include many more variations.

That is, for example, in FIGS. 1a and 2a, the long hole 1d is provided in the stem part 1a, but since the structure is sufficient as long as the shaft part 1a can slide the support fitting 2 and can be tightened with bolts, A bolt hole may be provided in 1a.

Of course, in the example shown in FIG. 2, if a bolt hole is formed in the shaft portion 1a, the bracket mounting seat 10 cannot be moved in the front-rear direction.

In the case shown in FIG. 1a, the shaft portion 1a may be provided with a long hole 1d, or the support fitting 2 may be provided with a bolt hole.
The length is limited to the length of the elongated hole 1d.

In FIG. 1a, a plurality of bracket mounting seats 1 can also be mounted between the supporting fittings 2.

In addition, by combining the structures shown in FIG. 1a and FIG. 2a, the vertical support fitting 2 shown in FIG. 2 is attached to the horizontal support fitting 2 shown in FIG. can also be attached to the vertical support fitting 2 so as to be movable up and down.

Further, in FIGS. 1 and 2, welding allowances are formed at both ends of the support metal fitting 2, but welding allowances may be formed only at one end to simplify welding in a so-called cantilever type.

As embodied in the above embodiments, according to the present invention, a cable bracket can be attached to the central part of the plate body bent in a U-shape, excluding both bent shaft parts, along the longitudinal direction. While drilling holes, passing through elongated holes or bolt holes drilled in the plate-shaped support fittings corresponding to both of the above-mentioned shaft parts, and bolt holes or long holes drilled in both of the above-mentioned shaft parts, Alternatively, bolts are inserted and tightened so as to pass through the long holes drilled in the support metal fitting and both of the shaft parts, and the support metal fitting and the shaft parts are fastened at arbitrary positions. As a result, even if the individual specifications are different, the cable bracket can be mounted □ The bracket mounting seat and the cable bracket itself can be moved freely to match the specifications, eliminating troublesome work, unnecessary production costs, and production time. Even if you do not have to change the equipment or change the equipment, you can easily meet that request.

In addition, since there is a long hole in the center and devices with multiple bracket mounting seats are possible, it is possible to increase or decrease the number of cable head devices, and the thickness of the cable head can also be selected arbitrarily, and the installation pinch can be adjusted arbitrarily. You can choose.
