Description

High-stability interweaved and twisted self-adhesive covered wire

Technical Field

The utility model relates to a silk envelope curve technical field, concretely relates to high stability interweaves transposition self-adhesion silk envelope curve

Background

The common filament-covered stranded wire is a stranded wire formed by covering one or more layers of fibers on the surface of the stranded wire, comprises a polyester filament-covered wire, a nylon filament-covered wire and the like, has the advantages of wear resistance, scratch resistance and quick heat dissipation, and is widely applied to high-frequency transformers, inductance coils and the like; the self-adhesive wire wrapped stranded wire is formed by adding an adhesive layer on the outer surface of a common wire wrapped stranded wire and solidifying the adhesive layer through hot air to enhance the performance of the self-adhesive wire wrapped stranded wire, and is mainly used for manufacturing high-frequency components. However, the existing self-adhesive wire wrapped stranded wire can shrink greatly after being bonded by hot air, so that the outer diameter of the product is unstable, and the stability of electromagnetic induction is poor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the disappearance that prior art exists, provide a high stability transposition self-adhesion silk envelope curve that interweaves, its advantage that can synthesize ordinary silk envelope curve and self-adhesion silk twisted wire can appear contracting great phenomenon after avoiding hot-blast bonding for the product size external diameter is stable, and electromagnetic induction stability is better.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the high-stability interweaving-stranded self-adhesive-wire covered wire comprises a core wire, wherein the core wire is coated with interweaving-stranded parallel-wound fiber wires and self-adhesive wires, and the fiber wires and the self-adhesive wires are spirally wound outside the core wire in the same direction.

Preferably, the fiber yarn is polyester yarn.

Preferably, the self-adhesive filament is a nylon thermal fuse.

Preferably, the self-adhesive filament is a copolymerized nylon thermal fuse.

Preferably, the core wire is a single strand or a stranded wire.

As a preferable scheme, the stranded wire is a plurality of strands of enameled wires.

As a preferable scheme, the enameled wire is a round copper wire.

Preferably, the distance between two adjacent circles of fiber filaments is less than or equal to 0.5 mm.

Preferably, the distance between two adjacent circles of fiber filaments is less than or equal to 0.35 mm.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, specifically speaking, through adopting the mode of interweaving, stranding and winding in parallel to wrap the cellosilk and the self-adhesive silk outside the stranded wire, the cellosilk and the self-adhesive silk are separated from each other, on one hand, the product can avoid the phenomenon of larger shrinkage after hot air bonding, the product size external diameter is stable, the product performance is kept stable while the insulativity and the heat dissipation of the product are improved, and the electromagnetic induction stability is better; on the other hand, the fiber yarns and the self-adhesive yarns can be synchronously and uniformly coated on the surface of the stranded wire, and the two yarn coating processes are combined, so that the processing flow is reduced, the occupied volume is reduced, the quality is ensured to be stable, the productivity can be improved, and the performance of the product is prevented from being reduced by secondary processing.

To more clearly illustrate the structural features and technical means of the present invention and the specific objects and functions achieved thereby, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:
