Description

[Detailed explanation of the idea] This invention relates to electromagnetic equipment.

In general, in electromagnetic equipment, for example, an electromagnetic coil is inserted into the center leg of an E-type laminated core, and then the I-type laminated cores are joined and the joint corners are welded in the lamination direction of both to form a bare electromagnetic equipment. This is fixed to the mounting bracket by welding.

However, since this mounting bracket is larger and flat than the laminated end face of the E-shaped laminated core with which it comes into contact, it is difficult to weld the two together.

Furthermore, the heat dissipation effect of the mounting bracket cannot be expected.

This idea was devised in view of these points, and the purpose is to provide an electromagnetic device equipped with a mounting bracket that can be easily welded and also exhibits a heat dissipation effect when it is fixed to a mounting bracket by welding. That is.

A first embodiment of this invention will be explained based on FIGS. 1 and 2.

First, reference numeral 1 denotes an E-shaped laminated core with an electromagnetic coil 2 inserted into its central leg, and a ■-shaped laminated core 3 with the same lamination thickness is attached to the end faces of the central leg and side legs of this E-shaped laminated core 1. It is being

Mounting fittings 5 having two mounting holes 4 at the front and rear are provided along the stacking direction of the E-shaped laminated core 1.

A step portion 7 is formed in the center of the mounting bracket 5 to be joined to the bottom surface 6, which is the laminated end surface of the E-shaped laminated core 1.

That is, the width d1 of this stepped portion 7 is equal to the width d of the bottom surface 6.
.

The length 11 is the thickness width l of the bottom surface 6.

It is formed larger (111o in this example).

In such stealing, after inserting the electromagnetic coil 2 into the center leg of the E-type laminated core 1 and joining the I-type laminated core 3, the bottom surface 6 is brought into close contact with the stepped portion 7, and the EI joining direction and the lamination direction are E-type laminated core 1, I
Strong pressure is applied to the laminated core 3 and the mounting fittings 5 to perfect the floating, angle, etc. of the E-joint.

Then, in the stacking direction of the E-type laminated core 1 and the I-type laminated core 3, there are joint corners a, a', and the E-type laminated core 1 and the stepped portion 7.
and the corners in the stacking direction.

Weld b'.

As a result, the I-type laminated core 3 is welded and fixed to the E-type laminated core 1, and these are also fixed to the mounting bracket 5.

Here, when welding the corners S and b', the width d1 of the stepped portion 7 is the width d of the bottom surface.

Since they match, they are on the same plane and welding can be easily performed.

Furthermore, since the mounting bracket 5 is formed with a stepped portion 7, this stepped portion 7 provides a heat dissipation effect.

Note that it is best to weld the corners a, a', b, and b' at the same time to reduce the number of man-hours; however, they may be performed individually, or the corners a, a' may be welded in advance. .

In addition, in this embodiment, the stepped portion 7 of the mounting bracket 5 is brought into close contact with the bottom surface 6 of the E-type laminated core 1 and welded at the corners S and b', so the following advantages are also obtained. It is something.

That is, when welding the four sides of corners a, a', b, and b' at the same time to significantly reduce the number of man-hours, the distance between the welding machine's torch, etc., and the corner a will be reduced.

The minimum spacing of each of a', b, and b' is determined.

Therefore, a certain amount of distance is required between the welded parts.

By the way, it is also possible to attach the mounting bracket 5 in this embodiment to the ■-shaped laminated core 3 side, but in this case, the EI
The welding points of the mounting bracket 5 and I-type laminated core 3 become close to each other, and the distance between them becomes narrow, making it impossible to weld all four points at the same time, or even if it is possible, it is extremely difficult and welding is impossible. It becomes complete.

However, according to this embodiment, corner a. Since the distances a, b, and b are provided, simultaneous welding can be performed without such inconvenience.

Furthermore, it prevents the noise that occurs when the laminated core is not completely fixed, such as when welding is incomplete and a part of the laminated core is floating.1. However, in this respect as well, if welding is performed as in the embodiment, the spacing between welded parts can be averaged and noise will be reduced compared to the case where the mounting bracket 5 is welded and fixed to the side of the ■-shaped laminated iron core 3.

Next, a second embodiment of this invention will be explained based on FIGS. 3 to 5.

In this embodiment, the direction of the mounting bracket 5 in the previous embodiment is changed, and the length of the stepped portion 7 is l, and the width of the bottom surface 6 is d.
.

and the width d1' of the stepped portion 7 is the thickness width l of the bottom surface 6.
.

It was made to match.

Even with such a configuration, welding can be performed in the same manner as in the embodiment described above, and a heat dissipation effect can also be obtained.

In the case of this embodiment, when welding the corners s and b' between the bottom surface 6 and the stepped portion 7, since the stepped portion 7 is formed into a stepped portion 8 as shown in FIG. easy.

This idea forms a step on the mounting bracket with a width or length that matches the width of one side of the laminated core, so the corners of the core and the corners of the step are aligned in the stacking direction and welded. As a result, it is possible to reliably weld the necessary locations with unidirectional feed, and the step section can provide heat dissipation.In particular, the bottom surface of the E-type laminated core is brought into close contact with the step section, making installation easier. The distance between the welded part with the metal fittings and the welded part with the ■-type laminated core can be set large, which makes welding work easier, and the intervals between the welded parts can be uniformly distributed overall. This has the advantage of producing less noise.
