Abstract
The utility model provides a wire cable, which comprises an inner core, wherein, the outside of the inner core is covered by an insulating layer, and the outer surface of the inner core is provided with an anti-oxidation layer. The wire cable of the utility model has the advantages of good electrical conductivity, oxidation resistance, acid resistance, alkali resistance, and less oxidation in the air, and can ensure electrical wires to be safely used under rated current for long.
Description
The utility model relates to a kind of electric wire, cable.
At various power set, electrical equipment, in the field such as instrument and telecommunication apparatus, electric wire, the cable part that is absolutely necessary, and its use amount is very big, at present, adopt copper or other electric conductivity electric wire made of electric conductor preferably always, cable, this electric wire, the inside of cable is the flavous bare copper conductor of one deck or other electric conductivity preferred metal conductor, it is inner core, the outside coats one deck plastic cement as insulated part, the electric wire that this copper or other electric conductor are made, cable, electric conductivity is better, be widely used in various fields, various occasions, but this product is after installing and using, when varying environment is worked, the copper core can react with airborne oxygen, generate cupric oxide, even at some awful weathers, moist, seriously polluted, not only under the environment of acid but also alkali, this electric wire, cable will produce " verdigris " at short notice, it is cupric oxide, this material has formed one semiconductor layer between wire conductor and the appliance switch binding post after producing, and causes loose contact, along with electric wire, what variation of current-carrying capacity of cable, the lighter causes the electric wire heating, and voltage reduces, and influences electric wire, normally the using and powering of cable, weight person causes electric wire overheated, cause on firely, cause fire, threaten people's the security of the lives and property.Therefore, this electric wire, cable have certain danger owing to the generation of this oxidation in actual use, can not satisfy instructions for use well.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of electric wire, cable are provided, conduct electricity very well, and also anti-oxidant, antiacid, alkali resistant, be difficult for reacting with airborne oxygen, can guarantee electric wire safety, use chronically under rated current.
To achieve these goals, the utility model provides a kind of electric wire, cable, comprises inner core, and this inner core external packets is covered with insulating barrier, and one deck anti oxidation layer is arranged on the outer surface of inner core.
The utility model also can further comprise following technical characterictic: anti oxidation layer is the tin coating at the outer surface of inner core.
Inner core can be the copper core; Also can be the aluminium core.
Inner core can be one; Also can be one group; The outer surface of every inner core can all have anti oxidation layer in one group of inner core.
The insulating barrier of this electric wire, cable can be the polyvinyl chloride insulation layer.
This electric wire, cable also can be provided with sheath; This sheath can be insulation vinyl chloride sheath.
Adopt structure of the present utility model, owing to be provided with one deck anti oxidation layer in core surface, for example: can plate one deck tin at interior core outer surface, because tin metal itself is acidproof, alkaline-resisting, react hardly with oxygen, be not subject to harsh weather or environmental impact, can protect inner core to make it that oxidation reaction can not take place or influenced by bad working environment and influence its electric conductivity, therefore, use the electric wire of this structure, cable is during as wire conductor, have anti-oxidant, antiacid, many-sided effect such as alkali resistant, thus electric wire prolonged, in the work useful life of cable, also guaranteed electric wire energy safety under rated current, use chronically; And, adopt the electric wire of this structure, the electric conductivity that cable can not reduce copper conductor itself, so electric conductivity is better.
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model;
Fig. 3 is the structural representation of the third embodiment of the utility model.
Referring to Fig. 1, a kind of electric wire, cable comprise inner core 1, and this inner core 1 external packets is covered with insulating barrier 3, and one deck anti oxidation layer 2 is arranged on the outer surface of inner core 1.
In the present embodiment, anti oxidation layer 2 is the tin coating at the outer surface of inner core 1.
The insulating barrier 3 of electric wire, cable is the polyvinyl chloride insulation layer.
Electric wire, cable also can be provided with sheath 4; This sheath 4 can be insulation vinyl chloride sheath.
Adopt structure of the present utility model, owing to be provided with one deck anti oxidation layer 2 on inner core 1 surface, for example: can plate one deck tin at inner core 1 outer surface, because tin metal itself is acidproof, alkaline-resisting, react hardly with oxygen, be not subject to harsh weather or environmental impact, can protect inner core 1 to make it that oxidation reaction can not take place or influenced by bad working environment and influence its electric conductivity, therefore, use the electric wire of this structure, cable is during as wire conductor, have anti-oxidant, antiacid, many-sided effect such as alkali resistant, thus electric wire prolonged, in the work useful life of cable, also guaranteed electric wire energy safety under rated current, use chronically; And, adopt the electric wire of this structure, the electric conductivity that cable can not reduce copper conductor itself, so electric conductivity is better.
Also can be with assembly bunchy embodiment illustrated in fig. 1, the outside coats layer protective layer 5 again, as shown in Figure 3; Perhaps structure of the present utility model is made electric wire, the cable of different shape, thickness and structure, to satisfy various demands as present use.
In addition, electric wire, cable with the copper inner core are example, in actual production, the manufacturing process of electric wire, cable is roughly as follows: when making cable, at first the stretched operation of raw material copper bar is drawn into the copper cash of specifying thickness, make copper cash softening by annealing operation again, through stranded operation, stranding operation, the inspection process of copper conductor, make cable then; When making electric wire, same, at first the stretched operation of raw material copper bar is drawn into the copper cash of specifying thickness, make copper cash softening by annealing operation again, directly carry out the extrusion molding operation then, again through inspection process, make electric wire.When making electric wire of the present utility model, cable; in the operation of producing electric wire, cable; after the annealing operation that copper cash is made it to soften; copper conductor is carried out zinc-plated processing; then it is carried out air-dry, add protectant operation; also promptly plate the even and level and smooth argenteous tin layer of one deck on flavous copper conductor surface; like this; only need in the production process of electric wire, cable, inner core to be carried out zinc-plated processing; promptly increase anti oxidation layer, promptly can be made into zinc-plated, cable of the present utility model, therefore; production cost is low, and processing is simple and convenient.
Electric wire of the present utility model, cable can be made into various models and specification, to satisfy various instructions for uses, can be widely used in the various aspects and the every field of living, producing, be widely used in the high and low pressure power cable, electronic wire, in the every field such as the communications cable, it is safer that people are lived, more secure.
