Abstract

PURPOSE:To prevent disturbance of ordered condition of wire when a coil is pressurized, by forming an external insulation paper with a plurality of interlayer papers. CONSTITUTION:A coil 1 is formed by winding wire 3 to a core 2 through interlayer papers 4, the sectional area is reduced by applying external forces X and Y in the direction at a right angle to the axial center of coil 1 and a coil length is shortened by applying external pressure Z in the direction parallel to the axial center. The external insulation paper 8 is composed of a plurality of interlayer insulation papers. When the coil having such insulation papers 8 is pressurized with a pressurizing force Z, the papers 4, 8 are bent from the waste and ordered wire is not disturbed.

Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a coil for a discharge lamp ballast.

In this type of coil, the electric wire is wound around the core in a multi-layered manner with an interlayer paper interposed while the coil is lying down, and the distance between the layers is further shortened by applying pressure in the direction perpendicular to the center of the winding. In addition to reducing the cross-sectional area by applying pressure in the direction parallel to the axis, the manufacturing method in which the distance between adjacent turns in each layer is shortened and the coil length is shortened is described in a separate book. → Proposed by the inventor.

1. Winding the T-piece 3 around the winding core 2 with interlayer paper 4 interposed. Pressure forces X and Y are applied in the direction perpendicular to the axis of the coil 1 to reduce the cross-sectional area, and a pressure force is applied in the direction perpendicular to the axis of the coil 1. Add Z to shorten the coil length (/-. Pressure applied to this is the second
If the coil 1f winding device is inserted into the core leg 5 as shown in the figure, and pressure is applied from each direction, it will be more effective.
In addition, when applying pressure Z, press one end of the coil to the core leg 6 that intersects with the core leg 5, and press the pressing tool 7 from the other end to apply pressure. In general, the external insulating paper (insulating paper wound on the outermost layer) of this type of coil 1 must not have a thickness of 0.3 mm or more, probably because of the standard. Therefore, in the past, the thickness was 0.
Double-wrap 18 fl insulating paper =) Make J-1- and layer it with regular and 1-. L7 However, since it is thick, insulating paper of this thickness will not bend (Inode - As mentioned above, the pressure Z
- If the edge of the insulating paper (normally, the edge is located further outside than the outermost wire) bends in the cage (for example, in a zigzag pattern) This is because if there is any bending on the surface of the wire, it may be difficult to wind the wire in an aligned manner. The purpose of reducing the cross-sectional area and length could not be satisfied.The object of the present invention is to prevent the alignment of electric wires from being disturbed even by the presence of external insulating paper.

This invention is characterized by using a layer of insulation paper (17) for the outer insulating paper (17). In other words, the interlayer paper 4 is generally jgA
GaQ, Q5N+11. Or, it is a thin material of about 008, and therefore, it is much weaker than the external insulating paper that has been used conventionally. Increase the thickness as required by the standard. Tofuba thickness 005 interlayer paper 7 or 1
Just use one sheet of interlayer paper with a g-thickness of 0.08πm. 8 indicates a plurality of sheets of interlayer paper or an external insulating paper.In the case of 11i, one set of layers 11i may be wound one on top of the other, or may be wound in multiple layers (c).

When 1,000/L/ having external insulating paper with the structure as shown above is pressurized with pressure Z as described above, as shown in part 3-, each interlayer paper 4 is bent at the edge of the edge and the core leg is formed. 6 (or pressing tool 7

As detailed above, according to the present invention, when compressing the coil to shorten the coil, a plurality of sheets of interlayer paper are used as external insulating paper.1. Therefore, when pressurizing, it will cause disturbance in the way it folds (knee end Kf, bending force from the waist). This has two effects:
