Abstract
The utility model discloses a twisted polyurethane enamelled copper alloy wire which is mainly twisted by a plurality of groups of polyurethane enamelled copper alloy wires. The polyurethane enamelled copper alloy wire comprises a copper alloy wire core and a polyurethane paint insulating layer, wherein the polyurethane paint insulating layer is coated on the surface of a copper alloy wire. The twisted polyurethane enamelled copper alloy wire not only has excellent performances of high frequency resistance and humidity resistance and is easy to color, but also has excellent tensile strength; moreover, with adoption of a multi-strand twisting way, the twisted polyurethane enamelled copper alloy wire can greatly reduce overall temperature rise and skin effect losses, ensure the alloy wire to have better product performance when in use and can meet using requirements of more occasions.
Description
Technical field
The utility model relates to a kind of wire rod structure, especially a kind of stranded polyurethane paint copper-clad alloy wire.
Background technology
Enamelled wire is a kind of electric wire with insulating barrier, and it can be applied on general motor, electrical equipment, the instrument.Polyurethane enamelled wire is a kind of very common enamelled wire product, it has good anti-high frequency, anti-moisture performance, easy coloring, be widely used on electronic appliance and precision instrument, telecommunication products, the instrument, but the pliability and the tack of the polyurethane enamelled wire in big gauge wire footpath are relatively poor, result of use and bad, therefore the present polyurethane enamelled wire of producing all is to be many with medium and small and glass-coated microwire.The scope of application of the polyurethane enamelled wire in this line footpath is extremely limited, and is not suitable for using in the occasion that heater wire, electromagnetic oven coil, high frequency transformer etc. are all had relatively high expectations to overcurrent capability and performance such as heat-resisting.
Summary of the invention
For addressing the above problem, the utility model provides that a kind of overcurrent capability and heat resistance are all higher, the more reliable check polyurethane paint of quality copper-clad alloy wire.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of stranded polyurethane paint copper-clad alloy wire, mainly by stranded the forming of plural groups polyurethane paint copper-clad alloy wire, described polyurethane paint copper-clad alloy wire comprises copper alloy core and polyurethane paint insulating barrier, and described polyurethane paint insulating barrier is coated on the surface of copper alloy wire.
As preferred embodiment, described polyurethane paint copper-clad alloy wire is the circle line.
As preferred embodiment, the diameter of described polyurethane paint copper-clad alloy wire is not less than 0.1 millimeter.
As preferred embodiment, stranded polyurethane copper alloy wire also comprises the Membrane cover that is used for described plural groups polyurethane paint copper-clad alloy wire coating.
The beneficial effects of the utility model are: the utility model is with the stranded bigger enamelled wire product in line footpath that obtains of plural groups polyurethane paint copper-clad alloy wire, this product is except having good anti-high frequency, moisture resistance, easy coloring performance, also has good tensile strength, and the form of this strands can reduce whole temperature rise and skin effect losses greatly, product performance in use is better, can satisfy the instructions for use of more occasions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the overall structure generalized section of a kind of embodiment of the present utility model;
Fig. 2 is the overall structure generalized section of the another kind of embodiment of the utility model.
Embodiment
See figures.1.and.2, a kind of stranded polyurethane paint copper-clad alloy wire of the present utility model, mainly by plural groups polyurethane paint copper-clad alloy wire 1 stranded forming, described polyurethane paint copper-clad alloy wire 1 comprises copper alloy core 2 and polyurethane paint insulating barrier 3, and described polyurethane paint insulating barrier 3 is coated on the surface of copper alloy core 2.Polyurethane paint copper-clad alloy wire 1 adopts copper alloy core 2 as conductor material, and the tensile property of copper alloy core 2 is good, with common enamel covered wire mutually specific strength exceed 50%.Polyurethane paint copper-clad alloy wire 1 need carry out good allotment to lay and net mould distance in carrying out stranded process, guarantee can not take place broken string, jumping thigh and few burst of phenomenon of copper alloy wire 1.
In the product of reality, polyurethane paint copper-clad alloy wire 1 is generally round line, shown in the embodiment among Fig. 1 and Fig. 2.Certainly, polyurethane paint copper-clad alloy wire 1 also can be flat line, special-shaped line etc.
During application, in order to guarantee the quality of twisted wire, the diameter of polyurethane paint copper-clad alloy wire 1 generally is not less than 0.1 millimeter.When polyurethane paint copper-clad alloy wire 1 line when directly being 0.1 millimeter, the utility model at most can be stranded 1600 groups polyurethane paint copper-clad alloy wire 1, make the external diameter of integral product can reach 3.5 millimeters, the product of this external diameter has enough good tensile strength, conveyance capacity and heat resistance.
In addition; in some embodiment of the present utility model; in order to make the twisted wire structure compact more; stranded polyurethane copper alloy wire also preferably includes the Membrane cover 4 that is used for described plural groups polyurethane paint copper-clad alloy wire coating; shown in the embodiment among Fig. 2, this Membrane cover 4 can also play the effect of protection to polyurethane paint copper-clad alloy wire 1.
Execution mode of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
