Abstract

The utility model discloses a multilayered insulating layer's enameled wire, including: third insulating layer outside the enameled wire of enameled wire, cladding, arrange enameled wire inside second insulating layer, first insulation layer in, the first insulation layer is the combined material that shocks resistance, and the insulating properties of three -layer insulating layer improvement product is adopted in this patent application, improves the mechanical properties of product simultaneously through modified polyamidoimide, and national standard mechanical properties passes through wire film cutting round, and 15% tensile epidermis has insulated to stick up and has been less than 1 times of conductor width, and 20% tensile epidermis of this product has insulated to stick up and has been zero.

Description

A kind of enamel-covered wire of multilayer dielectric layer

Technical field

The utility model is related to enamel-covered wire field, specifically, is related to a kind of enamel-covered wire of multilayer dielectric layer.

Background technology

Current enamelled winding wire is widely used in motor, illumination, automobile and other industries.Enamel-covered wire is divided according to its heat resistance Into multiple grades, existing enamelled winding wire is mostly polyester-imide enamelled winding wire, and its flexility is limited, can not Meet requirement of the winding wire to mechanical performance.

Utility model content

The utility model provides a kind of paper insulation enamel covered wire, the suppleness of enamel-covered wire is improve, in order to reach above-mentioned mesh , the utility model uses following technical scheme：Include：Enamel-covered wire, the 3rd insulating barrier being coated on outside enamel-covered wire, it is placed in paint The second insulating barrier, the first insulating barrier inside envelope curve, first insulating barrier are impact resistant composite material.

Preferably, first insulating barrier uses polyamidoimide insulating coating, and its heatproof reaches 220 DEG C, and described the One insulating barrier is preferably the modified polyamide imide material of EMA HP661 models, and the thickness of first insulating barrier is 0.02mm。

Preferably, second insulating barrier is coated on the outside of the first insulating barrier, and second insulating barrier is polyamide acyl Imines coating, the thickness of second insulating barrier is 0.10mm.

Preferably, using aromatic polyimide material, the thickness of the 3rd insulating barrier is the 3rd insulating barrier More than 0.30mm.

The beneficial effects of the utility model：Present patent application improves the insulating properties of product using three-layer insulated layer, while The mechanical performance of product is improved by modified polyamide imide, national standard mechanical performance cuts one by wire paint film Circle, stretching 15% epidermis insulation warps less than 1 times of conductor width, and it is zero that this product stretches the insulation of 20% epidermis and warps.

Brief description of the drawings

Fig. 1 is structural representation of the present patent application on enamel-covered wire cross section；

In figure, the 1, first insulating barrier, the 2, second insulating barrier；3rd, enamel-covered wire；4th, the 3rd insulating barrier.

Specific embodiment

Understood shown in Fig. 1, present patent application is included：Enamel-covered wire, the 3rd insulating barrier being coated on outside enamel-covered wire, it is placed in paint The second insulating barrier, the first insulating barrier inside envelope curve, first insulating barrier are impact resistant composite material.

This patent product, in its national standard measuring mechanical property, is enclosed by cutting one to wire paint film, stretches 15% table Skin insulation warps less than 1 times of conductor width, and it is zero that this product stretches the insulation of 20% epidermis and warps.

The principle and its effect of above-described embodiment only illustrative present patent application, not for limitation this patent Shen Please.Any person skilled in the art can all be carried out under without prejudice to the spirit and scope of present patent application to above-described embodiment Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in present patent application All equivalent modifications completed under god and technological thought or change, the claim that should be asked by this patent are covered.
