Abstract
The utility model discloses a strippable-type three-layer insulated wire, which comprises a conductor, wherein a polyethylene terephthalate (PET) basic insulating layer, a voltage-resistant insulating layer which is formed by compounding PET and polybutylene terephthalate (PBT) and a polyamide (PA) nylon wear-resistant insulating layer are sequentially arranged outside the conductor. The strippable-type three-layer insulated wire has the characteristics that: the insulated wire is convenient to use, the size of a transformer after being wound by wires can be reduced, and the labor work time and the processing procedures can be reduced. The utility model is characterized in that: the three-layer insulated wire is convenient to be stripped, and at the same time, the strippable-type three-layer insulated wire is applied to transformers, digital top sets, inductance coils, micro motors and the like in consumption electronic products that the three-layer insulated wire is required to be stripped.
Description
Technical field
The utility model relates to a kind of insulated wire, specifically is a kind of peelable integumentary pattern three layer insulation wire.
Background technology
Enamelled wire is a principal item of winding wire, and normally with the bare wire annealing softening, cure through japanning and form again, general enamelled wire comprises conductor and insulating barrier two parts.With common enamelled wire during around transformer framework, because of general transformer is withstand voltage is 4000V, and common enamelled wire withstand voltage be 1500V, can't reach the requirement of withstand voltage of transformer, enamelled wire is around to transformer framework, in order to reach withstand voltage 4000V, can only between each layer enamelled wire, add insulating barrier, make it to reach 4000V, so cause the waste of insulating material, increased labor hour and manufacturing process, increased the volume of transformer again.Therefore, need a kind of saving insulating material, reduce labor hour and manufacturing process, simultaneously can in case with peeling or scolding tin can not residual scruff when the tin stove, the residue effect is not stayed in peeling, and can not increase the wire rod of transformer finished-product volume.
The utility model content
At the direct scolding tin of other straight weldering type three layer insulation wire, and can not peeling, when peeling requires or directly scolding tin has the residual problem of scruff again, and the utility model provides a kind of peelable integumentary pattern three layer insulation wire, and scheme of the present utility model is:
Peelable integumentary pattern three layer insulation wire comprises conductor, is provided with PET basis insulating barrier, PET and PBT be composited withstand voltage insulating barrier and PA nylon abrasion-proof insulating layer successively at described conductor skin.
Preferably, the basic thickness of insulating layer of described PET is 0.02～0.03mm.
Preferably, described PET and the PBT withstand voltage thickness of insulating layer that is composited is 0.04～0.06mm.
Preferably, described PA nylon abrasion-proof insulating layer thickness is 0.02～0.03mm.
Preferably, described conductor is a kind of in enamelled wire, bare copper wire, the copper-clad aluminum conductor.
Above-mentioned utility model scheme has following advantage:
1, easy to use, peelable integumentary pattern three layer insulation wire directly is wrapped on the transformer framework, must not add other insulating material in addition.
2, owing to do not re-use insulating material, the feasible finished-product volume that reduces after transformer framework winds the line, thus scantlings such as this skeleton, magnetic core reduce, and reach the minimizing material cost, also have and reduce operation, the labor hour that adds insulating material, thereby reduce cost of labor.
But the laggard capable scolding tin of 3 peelings, the noresidue material.
4, scolding tin time weak point, fraction defective significantly reduces.
5, product withstand voltage properties height, requirement of withstand voltage just reaches 6000V when producing three layer insulation wire, must not worry when producing product such as transformer withstand voltage bad because of material production.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model section structure schematic diagram.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
As shown in Figure 1, with enamelled wire as conductor 1, the basic insulating barrier 2 of PET (PETG) has been extruded by extruder in its outside, extruded PET and PBT (polybutylene terephthalate (PBT)) the withstand voltage insulating barrier 3 that is composited in the pet layer outside by extruder, extruded the abrasion-proof insulating layer 4 (reinforced insulation layer) that PA (polyamide) nylon material is made by extruder in PET and PBT withstand voltage insulating barrier 3 outsides that are composited.
Further, PET basis insulation layer by layer 2 thickness be 0.02～0.03mm.
Further, PET and PBT withstand voltage insulating barrier 3 thickness that are composited are 0.04～0.06mm.
Further, PA nylon abrasion-proof insulating layer 4 thickness are 0.02～0.03mm.
As the part alternative of such scheme, described conductor can also be a kind of in bare copper wire, the copper-clad aluminum conductor.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
