Abstract
The utility model discloses a straight welding type three-layer insulating wire with a tin-plated copper conductor, comprising a tin-plated copper wire, wherein a PET (polyethylene terephthalate) base insulating layer, a voltage-resistant insulating layer compounded by PET and PBT (polybutylece terephthalate), and a PA (polyamide) nylon wear-resistant insulating layer are arranged at the outer layer of the tin-plated copper wire in sequence. The three-layer insulating wire has the characteristics of being practical and convenient, reducing the volume of a transformer which is wound, and reducing labour hours and processing procedures, and meanwhile, the three-layer insulating wire is more suitable for high-temperature resistant environments (155 DEG C) and transformers, digital set top boxes, inductance coils, micro motors and the like in consumer electronic products applied at a high-temperature environment.
Description
Technical field
The utility model relates to a kind of insulated wire, specifically is a kind of tin-coated copper conductor and directly weldering type three layer insulation wire.
Background technology
Enamelled wire is a principal item of winding wire, and normally with the bare copper 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, can not increase the transformer finished-product volume again, simultaneously under some hot environment (155 ℃), enamel-cover line style three layer insulation wire (130 ℃), naked copper three layer insulation wire (130 ℃) are all inapplicable, so just use directly weldering type of this novel tin-coated copper three layer insulation wire.
The utility model content
Be 130 ℃ at enamelled wire conductor type three layer insulation wire, naked copper three layer insulation wire environment for use, and more can't use under the hot environment (155 ℃), the utility model provides a kind of tin-coated copper conductor type three layer insulation wire can satisfy under the hot environment (155 ℃) and has used, and scheme of the present utility model is:.
Tin-coated copper conductor and directly weldering type three layer insulation wire comprise tinned wird, are provided with withstand voltage insulating barrier and the PA nylon abrasion-proof insulating layer that PET basis insulating barrier, PET and PBT are composited successively at described tinned wird skin.
Preferably, the basic thickness of insulating layer of described PET is 0.02～0.03mm.
Preferably, the withstand voltage thickness of insulating layer that is composited of described PET and PBT is 0.04～0.06mm.
Preferably, described PA nylon abrasion-proof insulating layer thickness is 0.02～0.03mm.
Above-mentioned utility model scheme has following advantage:
1, easy to use, tin-coated copper conductor and directly weldering type three layer insulation wire directly are 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, thereby scantlings such as this skeleton, magnetic core reduce, reach material costs such as reducing insulating material, skeleton, magnetic core, also have and reduce operation, the labor hour that adds insulating material, thereby reduce cost of labor.
3, use in hot environment, be applicable under 155 ℃ of environment and use, improved security of products greatly.
4, transformer in the consumption electronic products under hot environment (155 ℃) and top box of digital machine, inductance coil, micro motor etc.
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 tinned wird as conductor 1, outside the tinned wird layer, extruded the basic insulating barrier 2 of PET (PETG) by extruder, outside pet layer, extrude the withstand voltage insulating barrier 3 that PET and PBT (polybutylene terephthalate (PBT)) are composited, outside the withstand voltage insulating barrier 3 that PET and PBT are composited, extrude the abrasion-proof insulating layer 4 (reinforced insulation layer) that PA (polyamide) nylon material is made by extruder by extruder.
Further, PET basis insulating barrier 2 thickness are 0.02～0.03mm.
Further, withstand voltage insulating barrier 3 thickness that are composited of PET and PBT are 0.04～0.06mm.
Further, abrasion-proof insulating layer 4 thickness of PA nylon are 0.02～0.03mm.
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.
