Abstract
A battery post having the good electric conductivity, belonging a power battery electrode field, includes a stud bolt which is characterized in that the stud bolt is provided with a fixed disk; the lower part of the fixed disk is fixedly connected with a bottom plate; and the bottom plate and the fixed disk are fixed through welding. By employing the method of dividing the stud bolt and its bottom plate into two parts, the stud bolt made of the pure copper material and the bottom plate made of the pure iron material are connected by welding so as to improve the electric conductivity and decrease the electric resistivity of the battery post to 17% of the original electric resistivity, thereby effectively increasing the electric charging and discharging properties of the battery.
Description
Technical field
The utility model provides a kind of battery electrode column with satisfactory electrical conductivity, belongs to electrokinetic cell electrode field.
Background technology
In the existing technology, the pole of square Ni-MH power cell connects with pole plate, and pole and its base plate are one, adopts the pure iron casting after machining forms, and resistivity is bigger, and the charge-discharge performance of battery is bad.If it is infeasible adopting the less fine copper casting of resistivity to form, because the lug (steel) of battery will weld with argon arc with the pole base plate, and copper and iron are (ways of gas welding be herein technology unallowed) that can't weld.
The utility model content
According to above the deficiencies in the prior art, problem to be solved in the utility model is: a kind of battery electrode column with satisfactory electrical conductivity is provided.
The technical scheme that its technical problem that solves the utility model adopts: a kind of battery electrode column with satisfactory electrical conductivity, comprise double-screw bolt, it is characterized in that: double-screw bolt is provided with fixed disk, the fixedly connected base plate in fixed disk below, base plate and fixed disk are fixing by welding.
During use, the base plate fixed polar plate constitutes storage battery with shell.Adopt double-screw bolt and its base plate to be divided into the way of two bodies, adopt gas welding to connect between double-screw bolt and the base plate, the raising electric conductivity.
Wherein preferred version is:
Described fixed disk bottom is provided with alignment pin, and base plate is provided with location hole, and alignment pin and location hole adapt.Install and convenient welding.
Described base plate adopts the pure iron material, and base plate is provided with 5-10 pole plate holddown groove that is parallel to each other, and described double-screw bolt and fixed disk adopt the fine copper material.Base plate adopts gas welding to be connected with double-screw bolt, improves electric conductivity.
The beneficial effect that battery electrode column had that the utlity model has satisfactory electrical conductivity is: be divided into the way of two bodies by adopting double-screw bolt and its base plate, double-screw bolt adopts the fine copper material, and base plate adopts the pure iron material, and the welding connection, improves electric conductivity.(originally the resistivity of pole is 1.0x10 can to make the resistivity of battery electrode column reduce to original 17%
-7Ω m, the resistivity of existing pole is 1.724x10
-8Ω m.) improved the charge and discharge performance of battery effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
