Battery bag exports positive and negative on/off road, goes collection, metal-oxide-semiconductor to go to block the output of whole group battery bag by IC on protection board；Protection board electricity
Road design protection mainly includes overcharging, cross put, excessively stream, short-circuit protection this four class；For this block of overcurrent protection, due to lithium-ion electric
The chemical characteristic in pond, if cell production companies define maximum no more than 3C (the C=battery capacities/small of its discharge current
When), when battery is more than 3C current discharges, it will cause the permanent damage of battery or safety problem (on fire, blast) occur；
So battery pack has to prevent the generation of excessively stream (heavy-current discharge for exceeding custom requirements) in use；But protection
What is used on plate is all electric elements, and product is in different use environments, and aging phenomenon can occur for electric elements to cause work(
It can lose, situation about not protecting occurs in whole group battery bag charge and discharge process.So, by certain ancillary equipment or circuit design
Deprotection battery pack is still insecure.It must change by the physical arrangement of single battery core lug and go to avoid the generation of excessively stream
It is just the most reliable.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of novel soft package battery extreme ear structure.
A kind of novel soft package battery extreme ear structure, including lug body and the tab that is overlying on body, in described
The longitudinal axis of body is provided with the first datum hole and the second datum hole that two centers of circle are overlapped with longitudinal axis, the left side of the first datum hole
Equidistantly provided with some via holes for being located at same transversal line with the datum hole；The right side of second datum hole is equidistantly provided with some with being somebody's turn to do
Datum hole is located at the via hole of same transversal line.
It is preferred that, the distance of the leftmost side via hole of the first datum hole apart from body leftmost side edge is per two neighboring auxiliary
Help the half of pitch-row between hole；Distance of the rightmost side via hole of second datum hole apart from body rightmost side edge is per adjacent two
The half of pitch-row between individual via hole.
It is preferred that, first datum hole, the second datum hole are identical with the radius of via hole, on the left of first datum hole
Via hole number and the second datum hole on the right side of via hole number it is consistent.
It is preferred that, the width of the body is 45mm, and thickness is 0.2mm；First datum hole, the second datum hole and via hole
Radius be 0.5mm；The via hole number of body longitudinal axis both sides is 7；The leftmost side via hole distance of first datum hole
The distance of the distance at body leftmost side edge and the rightmost side via hole of the second datum hole apart from body rightmost side edge is
1.5mm；The pitch-row of first datum hole and the second datum hole is 0.2mm.
The utility model provides a kind of novel soft package battery extreme ear structure, by being punched on lug body, can subtract
Small lug cross-sectional area, can break (disconnection) when bearing high current, it is to avoid battery bag occurs caused by high current continuous discharge
Overheat, bulging, on fire, blast phenomenon occur；Misplace punching mesh in order to prevent lug in process and assemble process interrupt rhegma
It is bad.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described.
The front view for the embodiment that Fig. 1 is proposed by the utility model.
Fig. 2 is Fig. 1 side view.
Numeral is represented in figure：
1st, body 2, tab 3, the first datum hole 4, the second datum hole 5, via hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
Generally：Soft bag lithium ionic cell positive electrode current uses aluminium pole ears, and negative pole uses nickel lug/nickel plating copper-base
Ear, lug thickness is from 0.1~0.3mm, 5~80mm of width, what the specification type selecting of lug was carried with cell
Size of current is relevant；Every square millimeter can bear 5~7A Ampere currents.
Embodiment：
Shown in Fig. 1 and 2, present embodiments providing has two groups on a kind of novel soft package battery extreme ear structure, lug body 1
The aperture being dislocatedly distributed, the first datum hole 3 and 7 via holes 5 on the left of it constitute one group of aperture, the second datum hole 4 and its right side
7 apertures of side constitute one group of aperture, and the transversal line distance of two groups of apertures is 2mm, and leftmost side via hole 5 is apart from left side edge
Distance and rightmost side via hole 5 are 1.5mm apart from the distance of right side edge, and the pitch-row per two neighboring hole is 3mm.
Before not punching, its thickness is 0.2mm, and width is 45mm, and cross-sectional area is 9mm2Maximum overload electric current is
