Abstract

The utility model discloses an ultra-micro lubricating self-adhesive line which comprises a conductor, an insulative material layer, a fusion forming layer and a lubricating layer. The conductor is wrapped by the insulative material layer, the surface of the insulative material layer is covered by the fusion forming layer and the lubricating layer is coated on the surface of the fusion forming layer. The nominal diameter of the conductor is no more than 0.015 mm. Because a metal conductor is low in diameter and high in precision, the volume of coils is reduced after coiling, volatility of the conductor is reduced, brakeage ratio is reduced, full-package rate is high, the metal conductor can be easily produced into a precision coil which is tightly arranged, and therefore miniaturization is achieved and product quality is improved. Because aromatic polymers are additionally arranged, hardness of skim films is improved, transformation is small and water absorption quality is low.

Description

A kind of ultra micro lubricates Self-binding cord

Technical field

The utility model relates to the enamelled wire technical field, is specifically related to the lubricated Self-binding cord of a kind of ultra micro.

Background technology

At present, in use poor adhesion, not easy-formation of the Self-binding cord that uses of market, winding volume after the coiling is large, and resistance fluctuation is large, and outage is high, the dishful rate is low, more than general 0.02 mm of specification, be 0.02mm such as IEC standard minimum, JIS standard minimum is 0.025 mm, usually tolerance is at ± 0.002 mm, the larger then tolerance of conductor size is larger, so that the conductor consistency of enamelled wire is poor, affects product effect in use.

The utility model content

The purpose of this utility model is to provide a kind of conductor diameter the little and high ultra micro Self-binding cord of precision, reduces the volume of the rear coil of coiling, falls low-resistance fluctuation, improves the quality of products.

For realizing this purpose, the utility model has adopted following technical scheme:

A kind of ultra micro lubricates Self-binding cord, comprise conductor, insulation material layer, melting shape layer and lubricating layer, described insulation material layer parcel conductor, the surface coverage of described insulation material layer has the described shape layer that melting, described lubricating layer is coated in and is melting shape layer surface, and described conductor nominal diameter is 0.015mm or less than 0.015mm.

Further, in the present embodiment, described conductor nominal diameter is 0.010mm, and the conductor tolerance is ± 0.0005mm, strictly controls tolerance, guarantees consistency, is conducive to reduce the large problem of electrical property fluctuation.

Further, in the present embodiment, described conductor nominal diameter is 0.005mm, and the conductor tolerance is ± 0.0005mm, strictly controls tolerance, guarantees consistency, is conducive to reduce the large problem of electrical property fluctuation.

Further, in the present embodiment, described insulating material layer thickness is 0.002-0.01mm, and the rear winding volume of can avoiding winding the line is excessive.

Preferably, in the present embodiment, the described shape layer that melting is aromatic polyamide, has added the aroma type polymer, improves epithelium hardness, is out of shape littlely, and water absorption is low, is melting temperature and is bringing up to 180-200 ℃, and coil can deliquescing.

The utility model contrast prior art has the following advantages: utilize the metallic conductor diameter little, precision is high, reduces the volume of the rear coil of coiling, fall low-resistance fluctuation, outage reduces, and the dishful rate is high, easily be processed into accurate coil, and arrange closely, realize miniaturization, improve the quality of products, added the aroma type polymer, improve epithelium hardness, be out of shape littlely, water absorption is low.

Description of drawings

Accompanying drawing 1 is the utility model schematic cross-section;

Accompanying drawing 2 is the utility model generalized section.

Embodiment

Referring now to accompanying drawing, further describe the utility model.

Such as Fig. 1, shown in Figure 2, a kind of ultra micro lubricates Self-binding cord, comprise conductor 1, insulation material layer 2, melting shape layer 3 and lubricating layer 4, insulation material layer 2 parcel conductors 1, the surface coverage of insulation material layer 2 has is melting shape layer 3, and lubricating layer 4 is coated in and is melting shape layer 3 surfaces, and conductor 1 nominal diameter is 0.015mm or less than 0.015mm.

Conductor 1 nominal diameter is 0.010mm, and conductor 1 tolerance is ± 0.0005mm, strictly controls tolerance, guarantees consistency, is conducive to reduce the large problem of electrical property fluctuation.

Conductor 1 nominal diameter is 0.005mm, and conductor 1 tolerance is ± 0.0005mm, strictly controls tolerance, guarantees consistency, is conducive to reduce the large problem of electrical property fluctuation.

Insulation material layer 2 thickness are 0.002-0.01mm, and the rear winding volume of can avoiding winding the line is excessive.

Melting shape layer 3 and be aromatic polyamide, adding the aroma type polymer, improving epithelium hardness, be out of shape littlely, water absorption is low, is melting temperature to bring up to 180-200 ℃, and coil can deliquescing.

The utility model is when work, being operating as of a whole production process, the employee can carry out the modulation of process equipment as required to the strict screening of carrying out of conductor 1 material, in order to meet the requirements of conductor 1 diameter, carrying out wire drawing (draws in comprising, little drawing), simultaneously repeatedly apply insulating varnish, then toast, and surface-coated, cooling, take-up detects, and coefficient of friction is a key parameter of ultra micro Self-binding cord, our company has added the material with own lubrification in lubricating layer, with the outside fats polymer of product, make ultra micro line confficient of static friction less than 0.08, because confficient of static friction is little, tensile strength reaches 151MPa, the rate of finished products made improves 3.4%, and needle pore defect is less than 1, the withstand voltage 300V(pole method that reaches of wire rod), the miniaturization of this Realization of Product motor coil, same model hollow-cup motor power ascension.

Above-described the utility model execution mode does not consist of the restriction to the utility model protection range.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection range of the present utility model.
