Description

[Detailed Description of the Invention] The present invention relates to the structure of a wound core electromagnetic inductor in which at least two wound cores are arranged in parallel, such as a single-phase external iron transformer using a wound core.

Conventionally, this type of electromagnetic inductor has winding cores 1, 2, and 2 arranged in parallel, as shown in FIGS. A coil 3 wound around the wound cores 1 and 2, and a tightening band 4 that tightens the wound cores 1 and 2 individually.
・5. Upper metal fittings 6 and 7 that cover the upper and side parts of the wound cores 1 and 2, an upper connecting rod 8 that connects the upper metal fittings 6 and 7, and a lower metal fitting 9 that covers the lower and side parts of the wound iron cores 1 and 2. 10,
A lower connecting rod 11 that connects the lower fittings 9 and 10. It was composed of a connecting plate 12 and the like that connects the upper metal fittings 6 and 7 and the lower metal fittings 9 and 10.

When moving or transporting the electromagnetic induction device that has been stolen as described above, hang a wire rope, etc., over the upper fittings 6 and 7, and when installing and fixing it, use the fixing holes provided in the lower fittings 9 and 10. I was using it.

In this way, the upper bracket 6 and
7. Lower metal fittings 9 and 10 are required, and wound cores 1 and 2 are required.
The connecting plate 12 was necessary to prevent the metal parts from coming out from the upper metal fittings 6 and 7 and the lower metal fittings 9 and 10.

An electromagnetic induction device having such a structure has a disadvantage in that it requires a large number of supporting members such as an upper metal fitting, a lower metal fitting, and a connecting rod, and requires a lot of time to assemble.

The purpose of this invention is to eliminate the drawbacks of the conventional structure mentioned above.
The present invention provides an electromagnetic inductor with a small number of support members and a short assembly time, which includes a wound core arranged in parallel, a tightening band provided on the outer periphery of the wound iron core that commonly tightens the wound core, and the above-mentioned. A connecting band provided between wound cores and having an annular portion at both ends, and a through rod passing through the annular portion of the connecting band, the tightening band being passed through the inside of the through rod in a dogleg shape. This is a wound core type electromagnetic inductor characterized by being bent and tightened.

This will be explained in detail below with reference to the drawings.

Figures 3 to 6 show one embodiment of the present invention.
The figure is a front view, FIG. 4 is a side view, FIG. 5 is an enlarged perspective view of a main part, and FIG. 6 is a perspective view of a connecting band.

A coil 3 is wound around wound cores 1 and 2 arranged in parallel, and the wound cores 1 and 2 are tightened by a common tightening band 13.

Between the wound cores 1 and 2, annular portions 14a and 14b are provided at both ends.
Insert the connecting band 14 having the annular portion 14 a
・14b is penetrated by the upper penetrating rod 15 and the lower penetrating rod 16.

By passing the tightening band 13 under the upper penetrating rod 15 and above the lower penetrating rod 16, the tightening band 13 is bent into a dogleg shape.

The lengths of the upper penetrating rod 15 and the lower penetrating rod 16 are as follows:
The lower penetrating rod 16 also serves as a connecting rod for lower fittings 17 and 18 that cover the sides of the wound cores 1 and 2.

11 is a lower connecting rod that connects the lower fittings 17 and 18.

In the wound core type electromagnetic inductor configured in this way, the common tightening band 13 is bent in a dogleg shape, so that the wound core 1
・The tightening force of 2 is equivalent to the conventional method using individual bands.

When moving or transporting the electromagnetic induction device, wire ropes can be hung on both ends of the upper penetrating rod 15 to lift it up, and installation and fixing can be done using the fixing holes provided in the lower metal fittings 17 and 18, as in the past. I can do it.

Further, since the lower penetrating rod 16 also serves as a connecting rod for the lower fittings 17 and 18, the wound cores 1 and 2 do not come out from the lower fittings 17 and 18.

As described above, since it has the same functions as the conventional one, the structure is simple, the number of parts of the support member is reduced, the material cost is reduced, and the assembly work time is also shortened.

Furthermore, since there is no upper metal fitting, there is no loss caused by leakage magnetic flux in the upper metal fitting, and the efficiency of the electromagnetic inductor is improved.

As explained above, the wound core type electromagnetic inductor according to the present invention has a simpler structure than the conventional wound iron core type electromagnetic inductor, has fewer supporting parts, can shorten the assembly time, and has low loss. It has many advantages such as:
