Description
Technical field
The utility model relates to a kind of welder used for solar batteries, relates to a kind of invention of novel extending composite solar battery photovoltaic welding belt aspect or rather.
Background technology
Photovoltaic welding belt is the welder be used on photovoltaic module, mainly plays the effect connecting conduction.The critical technical parameter of welding device comprises solderability, tensile strength, elongation, resistivity.Welding device conventional is at present the copper strip surface at a kind of high-elongation, high tensile, high connductivity, and the method being coated with tin by heat is prepared from.Often in solar cell connection procedure, welding device there will be the shortage of very little length, connects if adopt other carrying out to supplement, and needs to consume certain human resources; In addition, in order to reduce costs, welding device needs the cost and the weight that reduce electric conducting material.
As can be seen here, above-mentioned existing welding device still has many defects, needs to be improved.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing welding device exists, and provides a kind of novel extending composite solar battery photovoltaic welding belt.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the novel extending composite solar battery photovoltaic welding belt that the utility model proposes, comprise the belt body of longitudinal extension, belt body comprises spiral aluminium strip core, Copper Foil half band and tinning layer, Copper Foil half band is along axis doubling parcel spiral aluminium strip core, spiral aluminium strip core is the helical form belt body with being formed after the wrapped cylinder of aluminium strip isometric helix, and spiral aluminium strip core is flat by extruding; Copper Foil half band has tinning layer along the half surface-coated of axis, and along the axis direction of belt body, Copper Foil half band is segmented, has overlapping part between adjacent Copper Foil half band.
Better, above-mentioned Copper Foil half band is the length of every section of Copper Foil half band of segmented is 50 centimetres to 80 centimetres, and the length of adjacent Copper Foil half band overlapping part is 3 centimetres to 5 centimetres.
Better, the thickness of above-mentioned Copper Foil length of tape is 20 microns to 150 microns.
Better, the thickness of above-mentioned aluminium strip is 50 microns to 250 microns.
Better, the thickness of above-mentioned tinning layer is 10 microns to 50 microns.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model brings multiple advantage owing to adopting technique scheme, first, adopts spiral aluminium strip core to reduce weight, reduces costs, as conductor, and can extend; Secondly, Copper Foil half band can play the effect of conduction, attachment scolding tin; Again, Copper Foil half band is segmented, and the overlapping part of Copper Foil half band is to make welding have certain ductility; Again, Copper Foil half band has tinning layer along the half surface-coated of axis, can reduce the consumption of scolding tin, reduces cost, can play the effect of welding Copper Foil half band simultaneously, and after making installation, welding Copper Foil half band is by complete welded closure; Finally, the utility model provides a kind of Novel solder strip structure increasing conduction, reduce costs, have ductility, be conducive to installation.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, technological means of the present utility model is better understood for enabling professional and technical personnel, and can be implemented according to the content of specification, coordinate accompanying drawing to be described in detail as follows with preferred embodiment of the present utility model below.
