Technical field
The utility model relates to electrokinetic cell and makes the field, and especially a kind of electrokinetic cell is used coupling arrangement.
Background technology
Because electrokinetic cell generally all has high voltage and jumbo characteristics, and can carry out discharging and recharging of big electric current, especially in test, often to carry out the charge-discharge test of big multiplying power.The brace of the material that Ni-based grade is easy to weld can not bear high current because its resistivity is bigger, has influenced test result, even can bring safety problem.And the bigger materials such as copper base of conductivity can not effectively weld with pole, have influenced proper testing.
The utility model content
The technical matters that the utility model will solve provides a kind of simple in structure, can carry out the electrokinetic cell of high-current test and use coupling arrangement.
For addressing the above problem; A kind of electrokinetic cell of the utility model is used coupling arrangement; It is characterized in that: this electrokinetic cell comprises the conductive sheet and the brace that is connected battery electrode column and conductive sheet of conduction current with coupling arrangement; Said conductive sheet and brace are overlapping to weld together; Said conductive sheet and brace are provided with the pole through hole that connects conductive sheet and brace, and the position of the left and right sides of this pole through hole is respectively arranged with the rectangular through holes that is used to be welded to connect sheet and battery electrode column on the said conductive sheet, and the below of pole through hole is provided with the p-wire through hole on the said conductive sheet.
Be the welding position with the corresponding position of rectangular through holes on the said brace, this place, welding position is provided with the space that width is 1mm.
The material of said conductive sheet is a copper, and the surface of copper conductive sheet is coated with nickel.
The material of said brace is a nickel.
Adopt the electrokinetic cell of the utility model structure to use coupling arrangement, on the basis of existing technology, increased the brace that is easy to weld, conductive sheet conductive performance is good through brace is connected with battery electrode column; The rationality of member designs and perfection have significantly improved precision of test result and test process security property.
Description of drawings
Fig. 1 is the front view of the utility model electrokinetic cell with coupling arrangement.
Fig. 2 is the stereographic map of the utility model electrokinetic cell with coupling arrangement.
Embodiment
In order to make those skilled in the art person understand the utility model technical scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, shown in 2; The electrokinetic cell of the utility model is used coupling arrangement; This comprises the conductive sheet 1 and the brace 2 that is connected battery electrode column and conductive sheet 1 of conduction current; Said conductive sheet 1 and brace 2 are overlapping to weld together, and said conductive sheet 1 and brace 2 are provided with the pole through hole 3 that connects conductive sheet 1 and brace 2, and the somewhat larger in diameter of this pole through hole 3 is in the diameter of pole.
The position, the left and right sides of this pole through hole 3 is respectively arranged with rectangular through holes 4 on the said conductive sheet 1, and this rectangular through holes 4 is used to be welded to connect sheet 2 and battery electrode column.
The below of pole through hole 3 is provided with p-wire through hole 5 on the said conductive sheet 1, and this p-wire through hole 5 is used to connect p-wire.
Be brace 2 and the welding position of battery electrode column with rectangular through holes 4 corresponding positions on the said brace 2, this place, welding position is provided with the space 6 that width is 1mm.Welding effect good between brace 2 and the battery electrode column can be guaranteed in this space 6.
The material of said conductive sheet 1 can be the less alloy material of resistivity of main material with above-mentioned metal perhaps for copper, aluminium, gold, silver.But take all factors into consideration factors such as price and Practical Performance, preferably use the material of copper, and at its plating nickel on surface as conductive sheet 1.The thickness of conductive sheet 1 is greater than 1mm.
Said brace 2 is preferably nickel for being easy to the material with battery electrode column and conductive sheet welding.And the thickness of brace 2 is 0.5mm.
Adopt the electrokinetic cell of the utility model structure to use coupling arrangement, on the basis of existing technology, increased the brace that is easy to weld, conductive sheet conductive performance is good through brace is connected with battery electrode column; The rationality of member designs and perfection have significantly improved precision of test result and test process security property.
