Abstract
The utility model discloses a tinned wire, which comprises an inner conductor and a tinned layer, wherein the inner conductor is a copper conductive body and the thickness of the tinned layer is 2-3 mum. The electric wire has the advantages of light weight, saved material, large contact surface, and good electric conduction; the electric wire can endure high temperature and has large resistance and small current, and thus security performance which the electric wire is used can be improved; and the tinned wire can be an ideal wire for industries of communication, electronics and power. As the tinned layer is adopted, the material is safe and no pollution is caused to the environment.
Description
Technical field
The utility model relates to a kind of electric lead of electric line, relates in particular to a kind of tinned wire.
Background technology
Existing employed wire, all be at the center by a copper cash, its outside is surrounded by insulating barrier, and for the large wire of ampacity, conductor is to be combined and increased the flow of electric current by the strand copper wire coil buckling, and this wire can not be brought into play the flow in maximum unit cross section, because electric current all is easily to flow through from the outer surface of conductor, the central part flow is very little, and the structure of this kind wire does not meet the law of nature of electric current kelvin effect.In addition, the fine copper wire that uses in daily life in the easy oxidation of condition lower surface of high temperature, makes that its resistance is little, electric current is large, and fail safe is not high, can not bear high temperature.
For guaranteeing train apparatus and personnel's safety; must lay the ground wire cable of ground connection function admirable along the line; traditional earth cable adopts the version of copper clad lead; the effect of copper conductor is conduction, and sheath covers copper conductor, because lead material has the good corrosion resistance energy in soil and atmosphere; can protect copper conductor; avoid the corrosion of soil or the corrosion of atmospheric environment, plumbous have serious pollution to soil and environment, thereby affect people's health.
The utility model content
The utility model is in order to solve the easy oxidation of electric lead in the conventional solution, contaminated environment, the defective of poor electric conductivity.
In order to solve the problems of the technologies described above, a technical scheme of the present utility model provides a kind of tinned wire, comprising:
A kind of electric lead comprises inner wire and tin coating, and described inner wire is the copper electric conductor, and the thickness of described tin coating is 2-3um.
Wherein, the thickness of described tin coating is 2.5um.
Wherein, the end that namely is connected with electrical equipment of the two ends of described electric lead is respectively the spring-like wire.
Wherein, the outer surface of the tin coating of described electric lead, along its length continuously or be interrupted scribble non-drying glue layer, barrier film is posted in the outside of non-drying glue layer.
Wherein, the outer surface of described tin coating has planar section, and non-drying glue layer just is coated on this planar section.
Adopt the tinned wire of said structure shape, the thickness of tin coating is moderate, does not affect the performance of described copper cash, and described copper cash is played the effect of protection.Tinned wird and the copper cash that exposes are almost as broad as long on temperature and electrical property, their difference is that the aerial stability of tin coating is very high, because metallic tin has very strong passivation ability, generate rapidly one deck passivating film as thin as a wafer at surface energy, can resist the corrosion of atmosphere, alkali and some acid, in addition, the hardness ratio of tin coating is higher, can improve the resistance to wear of product surface.Described electric lead is lightweight, material saving, contact-making surface large, conduct electricity, described electric lead can sustain high temperature, high weldability, corrosion resistant tinned wire, it becomes wire desirable in communication, electronics, the power industry with the high conductivity of copper cash and thermal conductivity, corrosion resistance and the weldability of magnetic conductivity and tin.Adopt nickel coating, material safety, environmentally safe.
Description of drawings
Fig. 1 is the structural representation of cross section of the described tinned wire of certain execution mode of the utility model;
Label declaration:
Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with execution mode and cooperate accompanying drawing to give in detail explanation.
See also Fig. 1, the structural representation of certain execution mode of present embodiment electric lead, described electric lead comprises inner wire 1 and tin coating 2, described inner wire 1 is the copper electric conductor, the planform of described copper electric conductor can be designed to according to the needs of practical use different shapes, such as circular, square, rectangle, oval-shaped structure, in preferred embodiment, described inner wire 1 adopts square structure, and the planform of described copper electric conductor is so that the cross-sectional area of electric conductor is best execution mode to the maximum.Thereby make described electric lead can meet kelvin effect, reach maximum current delivery ability.In certain improved technical scheme; the thickness of described tin coating 2 is 2-3um; preferably; the thickness of described tin coating 2 is 2.5um, and tin coating 2 is unsuitable blocked up, the too thick material of not only wasting; and affect the conductive capability of described copper electric conductor; 2-3um is relatively more suitable thickness, can make described electric lead conductive capability best when the thickness of described tin coating 2 is 2.5um, and can play best protection to described copper electric conductor.
Be difficult for along bad, fracture when making described electric lead be that other electrical equipment connect, the technical characterictic that another improved procedure of the present utility model has is that the end that the two ends of described electric lead namely are connected with electrical equipment is respectively the spring-like wire.The tensile property of spring-like wire makes the described electric lead can free-extension, thus easy fracture not.
In certain improved technical scheme, the outer surface of the tin coating 2 of described electric lead, along its length continuously or be interrupted scribble non-drying glue layer, barrier film is posted in the outside of non-drying glue layer.This kind electric lead is when laying, as long as with hand barrier film is torn, one press on the wall with hand, non-drying glue layer will be sticking on the wall wire, wherein, the outer surface of described tin coating 2 has planar section, non-drying glue layer just is coated on this planar section, can judge the position of this non-drying glue layer with hand, and this plane is bonded at and spreads on the line plane, adhesive sticker also makes fixing more firm of wire, owing to can well glue glass, plastics, the things such as metal are so this wire also can well be fixed on these materials, this electric lead is as power line, the illuminating line telephone wire, install on television antenna cable and the power equipment dish with not only environmental protection of line, and the cost performance of using is high, and performance is good, can bear high temperature.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
