Abstract

(57) [Abstract] [Purpose] By facilitating the coating and coating of an electrical insulator or the thin layer coating insulation treatment on the surface of the conductor that forms the coil of the thin transformer, the thin transformer can be easily laminated and assembled. To reduce cost and make it a highly reliable and inexpensive thin transformer. [Structure] On a surface of a U-shaped conductor 2 and a spiral conductor 4 which form a coil of a thin transformer, an insulator 1 is previously formed on the surface of the conductor 2.
A thin transformer is formed by assembling an electric insulating layer formed by coating with a coating film or a thin film by insulation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to interlayer insulation of conductors of thin transformers.

[0002]

[Prior art]

 Conventionally, in this type of thin transformer, an insulator 12 made of an electrically insulating sheet, a U-shaped conductor 2 forming a coil, and a spiral conductor 4 are individually prepared as shown in FIG. Since the structure is such that these are stacked alternately when assembling the thin transformer, the insulation 12 is not leaked during the stacking at the time of assembly, and the safety such as electrical insulation between the upper and lower conductors due to the displacement of the insulation 12 However, there were drawbacks such as requiring a lot of man-hours for assembly and stacking work.

[0003]

[Problems to be solved by the device]

 In order to eliminate these drawbacks, the present invention has been conventionally used in which the front and back surfaces of a U-shaped or spiral-shaped conductor forming a coil are coated with an insulating material or electrically-insulated with a thin layer of insulating paper. It is designed to be stacked and assembled without using separate insulators.The present invention prevents electrical insulation failure due to the occurrence or displacement of non-inserted insulators during stacking, while reducing the number of stacking parts. The aim is to provide a highly reliable thin transformer with reduced assembly man-hours.

[0004]

[Means for Solving the Problems]

 The present invention is configured such that the spiral or U-shaped conductor is preliminarily coated or thinly insulated with an electric insulator so as to perform interlayer insulation between the conductors. The feature is that it is configured so that the interlayer insulation can be achieved at the same time only by stacking.

That is, according to the present invention, in a thin transformer in which a U-shaped thin plate conductor and a spiral conductor are stacked, the surfaces of the U-shaped conductor and the spiral conductor are electrically connected in advance. It is a thin transformer characterized by being coated or thin-layered with an insulator.

[0006]

[Action]

 In the conventional thin transformer, the interlayer insulation between the spiral conductor and the U-shaped conductor is performed by using a thin electric insulator and sandwiching the insulator between the conductors. By preliminarily thinly coating the body surface with an electrical insulator or performing thin layer coating insulation, it is possible to avoid the use of the conventionally used insulator. By adopting the thin transformer of the present invention, it is possible to obtain a thin transformer that is free from insertion of the insulator and insulation failure due to displacement of the insulator after the thin transformer is assembled.

【Example】

 FIG. 1 is an exploded perspective view of a thin transformer of the present invention, in which a U-shaped conductor 2 is coated with an insulating coating or a thin layer by means of an insulator 1, and between conductors and between a conductor and a ferrite. Electrical insulation is formed between the magnetic cores 11 when the conductors are laminated together. This prevents the risk of electrical short circuits between conductors due to the displacement of the insulators that occurs during stacking, and reduces the number of stacked assembly parts, resulting in a thin transformer that can reduce man-hours.

[0008]

[Effect of device]

 As described above, in the thin transformer according to the present invention, the surface of the electric conductor forming the coil is coated with an electric insulator in advance and is covered with a thin coating or a thin layer. It is possible to provide a thin transformer with higher reliability by preventing short circuits between them, and also having the advantage of cost reduction by reducing man-hours by reducing the number of coil stacks during assembly. .
