Description

A kind of cupro-nickel composite sheet
Technical field:
The present invention relates to cell connector technical field, more specifically to a kind of cupro-nickel composite sheet.
Background technology:
Today's society, as the improvement of people's living standards, the recoverable amount of automobile is also in cumulative year after year.Brought due to fuel vehicle Exhaust emissions problem is a key factor of current environmental pollution.Therefore, the new energy vapour such as electric automobile or hybrid electric vehicle Car arises at the historic moment, and they represent a developing direction of future automobile.In electric automobile, core is exactly as dynamic the most The power battery pack in power source.At present, lithium ion battery is because it has the advantages that energy density height, safety, small volume form For the preferred power source of people.Electrokinetic cell can be formed by serial or parallel connection between each cell of power battery pack Group, the various power demands of automobile are met with this.The electrode terminal of each cell carries out connection accordingly so that monomer is electric Serial or parallel connection is formed between pond, so as to form power battery pack.It is clear that due to electrokinetic cell electric power output terrifically Dependent on the attachment structure of electrode terminal, thus the attachment structure between the electrode terminal of each cell is for electrokinetic cell Performance impact it is larger, the reliability of the attachment structure, internal resistance etc. are close with the stability and electric power output performance of electrokinetic cell It is related.
In the prior art, the serial or parallel connection between power battery pack is connected by cell connector, and battery connects during connection One end of contact pin and the positive terminal of power battery pack connect, and the other end of cell connector and the negative pole end of power battery pack connect Connect, and cell connector is generally copper sheet or aluminium flake, the positive terminal of battery pack is aluminium, negative pole end is copper, when copper connection sheet and electricity When the positive terminal connection of pond group or the negative pole end of aluminium connection sheet and battery pack connect, because the normal potential of copper and aluminium differs greatly, connect When touching connection, in a humidity environment, electrochemical corrosion easily occurs.Electrochemical corrosion can cause contact internal resistance excessive so as to go out The problem of now overheating, have a strong impact on the performance of battery core.Therefore, it will usually do coating on the surface of junction, commonly use nickel plating.But Nickel plating technology is complicated, and pollution environment, costly, coating is thin, and binding force of cladding material is poor, and corrosion resistant performance is also poor.Chinese patent CN201210213370.4 discloses a kind of cupro-nickel composite sheet, including copper sheet and nickel sheet, by swashing between the copper sheet and nickel sheet Photocoagulation forms integrative-structure, and its advantage is to avoid the technique using nickel plating, but its shortcoming is:Its copper sheet and nickel sheet are monoblocks Weld together, after wherein a certain partial destruction, monoblock copper sheet or nickel sheet need to be changed, use cost is higher, easily causes The waste of resource.
The content of the invention:
The purpose of the present invention and provides a kind of cupro-nickel composite sheet aiming at the demand of existing market, its will it is some independently of each other Nickel sheet be arranged on copper sheet on, when a certain nickel sheet damage, only need to change corresponding nickel sheet, without by all nickel sheet progress more Change, effectively saved use cost.
The technology solution of the present invention is as follows:A kind of cupro-nickel composite sheet, including:One copper sheet and on the copper sheet Some separate nickel sheet, wherein, offered on the copper sheet with the one-to-one accommodating hole of the nickel sheet, it is described accommodating The side in hole forms groove, and the nickel sheet is arranged on the accommodating hole by the groove, and the nickel sheet includes one and institute State the corresponding rounded portions of accommodating hole and one and be arranged on bending part on the groove, the rounded portions are consolidated with the bending part Even, one end of the bending part forms solder joint, and the nickel sheet is welded on the copper sheet by the solder joint.
As the preferred of above-mentioned technical proposal, the accommodating hole is distributed in a manner of rectangular array on the copper sheet, institute It is square opening to state accommodating hole.
As the preferred of above-mentioned technical proposal, the quantity of the groove is arranged to 2, and the groove laid out in parallel is in described The side of accommodating hole.
As the preferred of above-mentioned technical proposal, the bending part is included through one first vertical portion of the groove and one the Two vertical portions, the horizontal part for connecting first vertical portion and second vertical portion, it is vertically set on second vertical portion Free end on and with the rounded portions be connected second connection end, be vertically set on the free end of first vertical portion First connection end, wherein, the solder joint is located on first connection end.
As the preferred of above-mentioned technical proposal, first connection end and the second connection end are oppositely extending.
As the preferred of above-mentioned technical proposal, four groups of connecting holes are provided with the copper sheet.
The beneficial effects of the present invention are:Some separate nickel sheet are separately mounted on copper sheet, when a certain nickel sheet During damage, corresponding nickel sheet only need to be changed, without all nickel sheet are changed, has effectively saved use cost, and make With easy to maintenance.
