Abstract
The utility model belongs to the field of parts of assembled batteries and particularly relates to a bonding pad of assembled batteries. A metal sheet with good conductivity and low internal resistance rate is taken as a main body substrate of the bonding pad of assembled batteries disclosed by the utility model. A through hole is drilled at each electrode position of the main body substrate. Metal sheets which have higher internal resistance rate and are easy for butt weld is taken as polar position pieces. The polar position pieces are shaped like a dish and are arranged in the through holes at each electrode position of the main body substrate by socket weld. The bonding pad has good conductivity and is easily fastened by butt weld, so that the bonding pad can meet the requirements of welding.
Description
Technical field
The utility model belongs to assembled battery accessory field, is specifically related to a kind of assembled battery bonding pad.
Background technology
The welding battery sheet that the assembled battery group adopts requires: one, self internal resistance rate of weld tabs is low, and electric conductivity is good; Two, good with battery welding performance, easily butt-joint is firm.But with the actual effect of butt-joint, self internal resistance of weld tabs is lower, and electric conductivity is better, and its welding effect is just poorer, and the rosin joint rate is also higher; On the contrary, self internal resistance of weld tabs is higher, and electric conductivity is poorer, and its welding effect is just better, and the rosin joint rate is lower.Such as, adopt copper sheet to be used as bonding pad, although electric conductivity is good, the poor effect of welding is almost rosin joint.If adopt stainless steel substrates to be used as bonding pad, although welding effect is fine, its self-conductive poor performance.If adopt pure nickel as bonding pad, although its welding effect is relatively good, electric conductivity is also poor.This is an industry the most nerve-racking difficult problem all the time.
Summary of the invention
The purpose of this utility model is for the defects that exists in prior art, and the assembled battery that a kind of electric conductivity is good and welding effect is good bonding pad is provided.
The purpose of this utility model realizes by the following technical solutions: this assembled battery bonding pad is to adopt electric conductivity is good, the internal resistance rate is low sheet metal as the main body substrate, gets through the hole at each electrode position of main body substrate; Adopt that the internal resistance rate is higher, the sheet metal of easy butt-joint is as utmost point bit slice, utmost point bit slice is made dish, and cover is welded in the through hole of each electrode position of main body substrate.
Specifically, described main body substrate adopts copper sheet to make, and described utmost point bit slice adopts pure nickel sheet or stainless steel substrates or nickel plating iron plate to make.
The utility model is combined by main body substrate and the welding of one or more utmost point bit slice, due to adopt the good metal copper sheet of electric conductivity as the main body substrate and easily butt-joint firmly sheet metal (mainly comprising pure nickel sheet, stainless steel substrates, nickel plating iron plate) as utmost point bit slice, existing so good electric conductivity can satisfy the requirement of welding aspect again, can be single electrode position or a plurality of electrodes positions on the main body substrate of the utility model Combination Welding sheet.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model embodiment.
Fig. 2 is the cross-sectional view of main body substrate in Fig. 1.
Fig. 3 is the cross-sectional view of utmost point bit slice in Fig. 1.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Referring to Fig. 1, in the present embodiment, the copper sheet that the employing electric conductivity is good, the internal resistance rate is low is as main body substrate 1, and in conjunction with Fig. 2, two electrode positions on main body substrate 1 (being the position of bonding pad and anode or negative pole welding) are got through hole 21; In conjunction with Fig. 3, adopt that the internal resistance rate is higher, the stainless steel substrates of easy butt-joint is as utmost point bit slice 2, and utmost point bit slice 2 is made dish, and cover is welded in the through hole 21 of two electrode positions on main body substrate 1, so just combined the assembled battery bonding pad.
