Abstract

The invention relates to electrical engineering, in particular to the manufacture of coil leads, and can be used in the electrical industry. The aim of the invention is to simplify the manufacturing technology, as well as ensure the density of the output. For this, the end of the tape 2 is bent at an angle of 45 ° to the edge of the tape and the bent end 4 is folded perpendicular to the edge of the tape. In addition, a metal strip 5 is placed on the bent end and is folded together with it. The leveling pad 6 is placed close to the edge of the tape and fold the bent end together with it. 2 hp f-ly, 7 ill.

Description

Fig.Z

The invention relates to electrical engineering, in particular to methods for producing the leads of coils, and can be used in the electrical industry.

The aim of the invention is the simplification of manufacturing technology.

Figure 1 shows the coil; Fig. 2 illustrates the bending operation of the end of the tape; FIG. 3 shows the installation of a metal strip and: a leveling pad; FIG. 4 shows the ending: after the output is folded; figure 5 - the tip after its reduction; in FIG. 6 is a section A-A in FIG. 5; 7 - section bb in fig. 5.

; The method is carried out as follows.

Y of the coil 1 wound from a tape 2, for example from a foil of constant width with an electrically insulating lacquer applied to its surface, wind off the end part, mark a bend line 3 at an angle of 45 ° to the edge of the tape and bend it, the length of the required lead is the distance from the end of the tape to the intended bend line 3 from the side of the tape 2, into which the tip will be bent. After that, a metal strip 5 is placed on the edge of the end 4 along the axis perpendicular to the edge of the tape 2. In addition, an alignment pad b is placed on the bent end 4 close to the edge of the main tape 2, the thickness of the alignment pad 6 is equal to the thickness of tape 2. After This ending 4 and the leveling pad 6 are folded around the metal strip 5 and pressed it in the plane of the tape 2. When not

A lead with a metal strip 5 is required, it may not be present when the tip is performed, in this case it is replaced by the bent edge of the tip 4. If the thickness of the tape 2 is small, the alignment pad 6 may also not be present.

The proposed method can be implemented with any thickness, length and width of the tape. Its use is most effective for coils made of thin sheet or foil, working in the high temperature region and under high mechanical loads, since this simplifies the manufacturing process.
