Self-adhesive polyester enameled flat copper wire

Technical Field

The utility model relates to an enameled wire technical field, in particular to autohension polyester enameled flat copper wire.

Background

The enameled wire is a main variety of winding wires and consists of a bare wire conductor and an insulating layer, and the bare wire is annealed and softened, and then is subjected to painting and baking for multiple times. However, it is not easy to produce a product which meets both the standard requirements and the customer requirements, and it is influenced by the quality of raw materials, process parameters, production equipment, environment and other factors, so that the quality characteristics of various enameled wires are different, but the enameled wires have four properties of mechanical properties, chemical properties, electrical properties and thermal properties. The self-adhesive enameled wire is a special enameled wire, and the manufacturing of the coil is simple and easy due to the special processing performance of the self-adhesive enameled wire. Wound coils are bonded and formed by heating or solvent treatment, and are therefore favored for use in the manufacture of various complex-shaped or frameless electromagnetic coils. The application of the self-adhesive enameled wire brings remarkable social and economic benefits, the coil forming process can be simplified, and the effect is improved, but the mechanical strength of the self-adhesive enameled wire is not high enough and is easily damaged by external force.

In addition, the existing enameled wires are all round and are not suitable for special occasions, so that a self-adhesive polyester enameled rectangular copper wire is needed to solve the problem.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model aims at providing a self-adhesion polyester enameled flat copper wire, the effectual current enameled wire intensity of having solved is not enough and can not be applicable to the problem of special cases.

The technical scheme of its solution is, the utility model discloses an alloy baseline, carbon fiber layer, polyurethane layer, diphenol propane type epoxy resin and amide imine resin, the up end of alloy baseline, terminal surface, left end face and right-hand member face are the plane down, the up end of alloy baseline and the handing-over department of left end face are the arc, the up end of alloy baseline and the handing-over department of right-hand member face are the arc, the lower terminal surface of alloy baseline and the handing-over department of left end face are the arc, the lower terminal surface of alloy baseline and the handing-over department of right-hand member face are the arc.

The utility model has the advantages that: the utility model discloses the structure is ingenious, and the design is novel, can satisfy the requirement of platyzization, lightweight, low-power consumption, high performance.
