Abstract
The utility model relates to a directly-welded enameled wire, comprising a metal wire core. The metal wire core is wrapped by an insulation varnish layer of polyamidoimide. A scolding tin layer and a pigmented layer are arranged between the metal wire core and the insulation varnish layer from inside to outside. The directly-welded enameled wire is good in heat resistance, high in mechanical strength and excellent in insulation property, can be welded without damaging the insulation varnish layer, and is high in welding efficiency. Pits are not easily formed in the surface of the metal wire core.
Description
Technical field
The utility model relates to a kind of technical field of enamelled wire,, particularly a kind of straight welding lacquered wire.
Background technology
The developments of enamelled wire product is at present: the electromagnetic wire product of taking as the leading factor with enamelled wire from developing the higher new varieties of thermal endurance, turns to the innovation of the coating of product structure, to reach the performance level that improves enamelled wire and the object of improving processing characteristics.Copper surface very easily forms oxidation spots, and metal-cored surface produces electric discharge phenomena, reduces the enamelled wire life-span, in the time that it carries out finished product welding, often there will be rosin joint, dry joint phenomenon, affects quality, in the time of welding, needs deface insulating barrier simultaneously.
Utility model content
The deficiency existing for prior art, the utility model provides a kind of straight welding lacquered wire, and it is simple in structure, prevents that hole from appearring in metal wire wicking surface, improves the enamelled wire life-span, and welding is without deface insulating barrier.
The utility model solves the technical scheme that its technical problem adopts: described straight welding lacquered wire, comprise that metal core, metal core are wrapped with insulation enamelled coating, and between metal core and insulation enamelled coating, be also enclosed with from the inside to the outside soldering-tin layer, dyed layer.
Further, described metal core is thread core of aluminum; Described metal core is also copper core; Described metal core is CCAM core.
For the ease of welding, improve infrared speed of welding, described soldering-tin layer is for there being lead welding tin, and dyed layer is nanometer four iron oxide coatings.
In order further to improve enamelled wire speed of welding and intensity, between described metal core and insulation enamelled coating, be only provided with soldering-tin layer, described soldering-tin layer is terne metal and Nano titanium nitride composite material.
In order to improve thermal endurance, mechanical strength, the insulation property of enamelled wire, described insulation enamelled coating is polyamidoimide.
The beneficial effects of the utility model are: the utility model good heat resistance, and mechanical strength is high, insulation property are superior, can weld enamelled wire without destroying insulating varnish, and welding efficiency is high, and metal-cored surface is difficult for producing hole.
