Abstract
The utility model discloses an enameled wire, and relates to the technical field of conductive wire rods. The enameled wire comprises a conductive core and an insulating layer which wraps the outer surface of the conductive core. The conductive core consists of an aluminium alloy core and a copper layer which is disposed on the outer surface of the aluminium alloy core. The copper layer is formed by that a copper belt wraps the outer surface of the aluminium alloy core, and comprises an annular body which is formed through wrapping welding and stretching. The insulating layer comprises: a non-conductive colloid layer which is coated on the outer surface of the copper layer; an insulating colloid layer which is adhesively bonded through the non-conductive colloid layer; and a surface coating layer which is uniformly coated on the insulating colloid layer. The beneficial effects of the utility model are that the enameled wire is good in conductive property and extension performance, employs the aluminium alloy core, is lower in cost, is lighter in weight, and is better in capability of impact resistance and performance of cold and damp resistance.
Description
Technical field
The utility model relates to a kind of wire rod, and in particular, the utility model relates to a kind of enamelled wire.
Background technology
Shielding processing is the requisite operation of whole machining process of existing electric wire, cable and signal transmssion line.While making cable braiding net and electronic devices and components pin plug-in unit in existing shielding processing operation, normal conditions all adopt pure copper wire, but by the thread conductor of this fine copper, the density of the mesh grid on this conductor is large, cost is high, and overall weight is heavy and large to copper resource consumption.In addition, the impact resistance of existing wire rod wire rod and the performance of cold-resistant tide are also more weak.
Summary of the invention
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provides one to be conducive to improve conductivity and extension property, has the low and lightweight enamelled wire of cost, and this enamelled wire has good shock-resistant ability and cold-resistant tide.
The technical solution of the utility model is achieved in that it comprises conductor wire core and is wrapped in the insulating barrier on conductor wire core outer surface, its improvements are: described conductor wire core is made up of aluminium alloy core and the copper layer being located on aluminium alloy core outer surface, and copper layer is the ring bodies that is wrapped in the outer surface of aluminium alloy core and is formed by clad welded with after stretching by copper strips; Described insulating barrier comprises the non-conductive colloid layer that evenly spreads upon on copper layer outer surface, by the bonding insulation colloid layer of this non-conductive colloid layer and evenly spread upon the face coat on insulation colloid layer;
Preferably, described face coat is polyurethane coating.
Preferably, the diameter of described enamelled wire is 2-5mm.
The beneficial effects of the utility model are: the utlity model has conductor wire core and be wrapped in the insulating barrier on conductor wire core outer surface, wherein conductor wire core is made up of aluminium alloy core and the copper layer being located on aluminium alloy core outer surface, and copper layer is the ring bodies that is wrapped in the outer surface of aluminium alloy core and is formed by clad welded with after stretching by copper strips, the enamelled wire of this structure, possess simultaneously and have good electric conductivity and extension property, and owing to having adopted aluminium alloy core, compare existing pure copper wire, its cost is lower, weight is also lighter, in addition, because the face coat of insulating barrier is polyurethane coating, therefore there is good shock-resistant ability and cold-resistant tide.
[accompanying drawing explanation]
Fig. 1 is schematic cross-section of the present utility model;
Fig. 2 is that this uses novel specific embodiment figure.
[embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
Shown in Fig. 1, a kind of enamelled wire that the utility model discloses, for the transmission technique field of electric energy or signal, this enamelled wire comprises conductor wire core 10 and the insulating barrier 20 that is wrapped in conductor wire core 10 outer surfaces, the diameter of enamelled wire is 2-5mm.
Further, described conductor wire core 10 is made up of aluminium alloy core 101 and the copper layer 102 being located on aluminium alloy core 101 outer surfaces, concrete, copper layer 102 is the ring bodies that are wrapped in the outer surface of aluminium alloy core 101 and formed by clad welded with after stretching by copper strips, and copper layer 102 and aluminium alloy core 101 are integrally welded, and this structure possesses simultaneously and has good electric conductivity and extension property, and owing to having adopted aluminium alloy core 101, compare existing pure copper wire, its cost is lower, and weight is also lighter.
Shown in Fig. 2, as preferred embodiment, above-mentioned insulating barrier 20 is by evenly spreading upon non-conductive colloid layer 201 on copper layer outer surface, consisting of the bonding insulation colloid layer 202 of this non-conductive colloid layer 201 and the face coat 203 that evenly spreads upon on insulation colloid layer 202, wherein, described face coat 203 is polyurethane coating, this structure, makes this enamelled wire have good shock-resistant ability and cold-resistant tide.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can there is various distortion and modification, retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
