Description

DETAILED DESCRIPTION OF THE INVENTION As shown in FIGS. 1 and 2, an inner cylindrical coil 11 and an outer cylindrical coil 12 formed by coil wires l of equal length arranged in parallel are fitted together. Combining and sequentially joining the linear parts to electrically close 1. 27. 4.4
-6, for example, iron-free, type.

It relates to a coil unit that is commonly used for coils such as armatures, and its purpose is to provide a coil unit whose overlapping portions can be easily joined. In order to form a closed loop in the outer cylinder, it is necessary, for example, to satisfy the following conditions.

That is, the coil wires 1 forming the inner cylindrical coil 11 and the outer cylindrical coil 12 are both made of the same number and are arranged in parallel on the cylindrical surface without overlapping. When fitting the coil 12, it is necessary that each coil of the outer cylindrical coil 12 (7) overlaps with each coil wire 1 of the inner cylindrical coil 11 in the radial direction at each end.

In the case where the coil wires l are placed in opposite directions, and when these are combined and fitted, the inner cylindrical coil □
Coil wire 1 of outer cylinder 5 coils 12 to coil wire 1 of 1
Rather than arranging them so that they are point symmetrical, they are fitted so that the coil wire l is shifted by one length at one end.

Conventionally, in order to join the coil wires 1 that overlap in the radial direction of the inner cylindrical coil 11 and the outer cylindrical coil 12, a bonding material 32 is inserted between the coil wires 1 that are spaced in the radial direction, as shown in FIG. This is done by cross-cutting or by melting and joining using a laser beam, etc.

However, when the inner cylindrical coil 11 and the outer cylindrical coil 12 are superposed, the coil wires 1 do not necessarily overlap neatly in the radial direction as shown in FIGS.
The drawback was that it was difficult to multiply by 2. If the direction in which the bonding material 32 is applied is not constant, it is not possible to automatically supply and produce the bonding material 32 automatically.

This invention seeks to eliminate the above drawbacks.

The present invention will be explained below based on an illustrative embodiment.

An embodiment of the present invention is shown in FIGS. 5 to 7.

In the drawings, 11 is an inner cylindrical coil, 12 is an outer cylindrical coil 12, and both are fitted so that the coil wires 1 overlap in the radial direction.

This is a 23-bar ring unit, and is formed by extending a bonding material 32 made of flexible metal between an outer ring 22 having the same diameter as the outer cylindrical coil 12 and an inner ring 21 having the same diameter as the inner cylindrical coil 11.

The outer ring 22 and the inner ring 214 are made of hard metal or synthetic wood.

Between the outer ring 22 and the inner ring 21, binding materials 32 made of a flexible metal such as solder, mild steel, or mild steel are spread at equal intervals in the radial direction so as to correspond to each of the coil wires 1.

This ring unit is superimposed so that the bonding material 32 is located on the coil wire l that overlaps in the radial direction, and the bonding material 32
At this point, the coil wires 1 having ridges in the radial direction of the row cylindrical coil 12 and the inner cylindrical coil 11 are joined.

The bonding material 32 and the 21-el wire 1 are bonded, for example, by irradiating both ends of the bonding material 32 with laser light. Also, when the bonding material 32 is solder, it is added with a heater! ! ) Can be easily joined by melting.

Therefore, when joining the bonding material 32 and the coil wires 1 that overlap in the radial direction, even if the coil wires l are not arranged regularly in the radial direction, the outer ring 22 and the inner ring 21 can be twisted relative to each other in the circumferential direction. This has the advantage that the flexible bonding material 32 can be easily aligned with the direction of the coil wires 1 arranged in the radial direction, and this bonding can be easily performed.

As described above, the iron-core type coil unit according to the present invention is arranged in parallel (the inner cylindrical coil jl and the outer cylindrical coil 12 formed by the coil wires 1 of the same length are fitted and combined, In a coil unit that forms an electrically closed loop by sequentially joining the bent portions, the outer cylindrical coil 1
An outer ring 22 with the same diameter as 2 and an inner cylindrical ring) A bonding material 32 made of flexible gold and metal is applied between the inner ring 21 and the inner ring 21 with the same diameter to form a ring ring 23!c. The coil 11 and the outer cylindrical coil 12''h are fitted together 4 so that the coil wires 1 overlap in the radial direction, and the ring unit 23
The bonding material 3.2 is positioned on the coil wire 1 that overlaps in half in one direction, so that the bonding material 32 overlaps the outer cylindrical coil 12 and the radius 5 of the inner cylindrical coil 11. Although it is characterized by joining coil wires 1 that overlap in one direction, even when the coil wires l are not regularly arranged in the radial direction, the outer ring 22 and the inner ring 21
Each binding material 3 becomes more flexible each time it is twisted in a relative circumferential direction.
2 can be easily aligned with the coil wires 1 arranged in the radial direction, and this has the advantage of being easy to join.
