The row's of drawing body is naked aluminium row.In order to realize drawing the good contact performance of wire connecting portion, the wire connecting portion of drawing of prior art generally adopts copper-aluminium transition row or copper clad aluminum wire structure, for example adopts copper bar or copper cover aluminum structure.But because the chemical characteristic between the copper aluminium itself, copper aluminium such as copper-aluminium transition row or copper clad aluminum wire overlap joint is prone to produce electrochemical corrosion, thereby causes the oxidation of the row of drawing and wear out, and causes contact performance not good easily.And, therefore also there is the higher shortcoming of cost because copper-aluminium transition row or copper clad aluminum wire need be electroplated thicker copper coating.
The utility model content
The technical problem that the utility model will solve provides that a kind of stable electrochemical property, oxidation resistance are strong, long service life, the row of drawing that is used for low pressure iron core aluminum reactor with low cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of row of drawing that is used for low pressure iron core aluminum reactor; Comprise and adopt aluminium to process the row's of drawing body; An end of the said row of drawing body is the coil aluminium strip connecting portion that is used for reactor winding aluminium strip welding; Another end is to be used to draw the wire connecting portion of drawing to client's wiring, and said top layer of drawing wire connecting portion is coated with copper layer and tin layer.
Further improvement as technique scheme:
Said tin layer is wrapped in outside the said copper layer.
Said tin layer is wrapped in the said copper layer.
The said row of drawing body is L shaped.
The utlity model has following advantage:.
1, the top layer of drawing wire connecting portion of the utility model is coated with copper layer and tin layer, comprises that the tin layer is wrapped in that the copper layer is outer, the tin layer is wrapped in two kinds of situation in the copper layer, has either way that stable electrochemical property, oxidation resistance are strong, the advantage of long service life.For outside the tin layer is wrapped in the copper layer, the tin layer can be isolated copper aluminium bridging arrangement and outside air, is difficult for producing electrochemical corrosion, is difficult for causing the oxidation of the row of drawing and wear out that contact performance is good; For in the tin layer is wrapped in the copper layer; The tin layer can be kept apart the aluminium of copper layer and the row's of drawing body; Thereby utilized the advantage of tin stable electrochemical property; Can overcome the shortcoming that the aluminium bridging arrangement is prone to produce electrochemical corrosion, be difficult for equally causing the oxidation of the row of drawing and wear out that contact performance is good.
2, the utility model can reduce the thickness of copper layer through compound two coating, reduces the use amount of copper,, advantage with low cost.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Embodiment one:
As shown in Figure 1; Present embodiment is used for the package of drawing of low pressure iron core aluminum reactor and draws together and adopt aluminium to process the row's of drawing body 1; An end of the row's of drawing body 1 is the coil aluminium strip connecting portion 11 that is used for reactor winding aluminium strip welding; Another end be used to draw to client's wiring draw wire connecting portion 12, the top layer of drawing wire connecting portion 12 is coated with copper layer 2 and tin layer 3.
As shown in Figure 2, in the present embodiment, the row's of drawing body 1 is for L shaped, and tin layer 3 is wrapped in outside the copper layer 2.For outside tin layer 3 is wrapped in copper layer 2; Tin layer 3 can be isolated copper aluminium bridging arrangement and outside air that copper layer 2 and the row's of the drawing body that adopts aluminium to process 1 are formed; Be difficult for producing electrochemical corrosion, be difficult for causing the oxidation of the row of drawing and wear out that contact performance is good.
Because common plating need be filled in electrolytic cell to the whole row of drawing; And therefore the coil aluminium strip connecting portion 11 of the row of drawing owing to need can not electroplate with the welding of coil aluminium strip; So the common electrical depositing process is undesirable; In the present embodiment needs are drawn wire connecting portion 12 and adopt Way by Brush Plating Technique separately, concrete technology is following: the negative electrode of brush plating power supply is connected conducting with the naked aluminium of the row of drawing body 1, with the anode tape splicing brush of brush plating power supply; Then at first with the copper electrolyte brush plating to drawing on the wire connecting portion 12, and then the brush plating of tin electrolyte is got on to get final product.
Embodiment two:
As shown in Figure 1; Row of drawing that embodiment two is used for low pressure iron core aluminum reactor and embodiment one are basic identical; Its identical point is, and: embodiment two equally also comprises and adopts aluminium to process the row of drawing body 1, and an end of the row's of drawing body 1 is to be used for the coil aluminium strip connecting portion 11 that welds with the reactor winding aluminium strip, and another end is to be used to draw draw wire connecting portion 12 to client's wiring; The top layer of drawing wire connecting portion 12 is coated with copper layer 2 and tin layer 3, and the row's of drawing body 1 is for L shaped.
As shown in Figure 3; Embodiment two is used for the row of drawing of low pressure iron core aluminum reactor and the difference of embodiment one is: tin layer 3 is wrapped in the copper layer 2; The concrete technology of Way by Brush Plating Technique is also slightly different in the present embodiment in addition: the negative electrode of brush plating power supply is connected conducting with the naked aluminium of the row of drawing body 1; With the anode tape splicing brush of brush plating power supply, then at first with the brush plating of tin electrolyte to drawing on the wire connecting portion 12, and then the copper electrolyte brush plating is got on to get final product.
For in tin layer 3 is wrapped in copper layer 2; Tin layer 3 can be kept apart the aluminium of copper layer 2 and the row's of drawing body 1; Thereby utilized the advantage of tin stable electrochemical property; Can overcome the shortcoming that the aluminium bridging arrangement is prone to produce electrochemical corrosion, be difficult for equally causing the oxidation of the row of drawing and wear out that contact performance is good.
The above is merely the preferred implementation of the utility model, and the protection range of the utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to the protection range of the utility model.For a person skilled in the art, some improvement and the retouching under the prerequisite of the principle that does not break away from the utility model, carried out, these improvement and retouching also should be regarded as the protection range of the utility model.
