Abstract
The utility model discloses an area overflows lithium battery tab of function of autotomying, including utmost point auricle, utmost point auricle one end inserts electric core external circuit, and the battery electrode is connected to the other end, and the through -hole has been seted up at utmost point auricle middle part through punching. The utility model discloses a lithium battery tab sets up the through -hole through punching at utmost point auricle middle part, makes utmost point auricle middle part current -carrying part narrow down, when because short circuit and when leading to too big current conveyance utmost point auricle, utmost point auricle plays the effect of protecting the battery in the part fusing in time on through -hole both sides limit.
Description
Technical field
This utility model relates to field of lithium, particularly relates to a kind of band and crosses stream and autotomy the lithium battery pole ear of function.
Background technology
The lug of lithium battery is responsible for connecting battery electrode and battery core external circuit, when the external circuit of battery is short-circuited, if the lug of battery disconnects in time, then inside battery can be protected not affected by external short circuit circuit, plays the effect of protection battery.But the lug of existing lithium battery is usually and is served as by the strip-shaped conductive bar that width is identical, it is difficult to fusing when short circuit occurs in circuit, it is impossible to play the effect of protection battery.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of band to cross stream to autotomy the lithium battery pole ear of function.
This utility model the technical scheme is that for solving its technical problem
A kind of band is crossed stream and is autotomyed the lithium battery pole ear of function, and including lug sheet, battery core external circuit is accessed in described lug sheet one end, and the other end connects battery electrode, offers through hole by punching in the middle part of lug sheet.
As the further improvement of technique scheme, described lug sheet offers more than one through hole.
As the further improvement of technique scheme, the generally circular in shape or rectangle of described through hole or square.
As the further improvement of technique scheme, described lug sheet connects battery negative electrodes.
The beneficial effects of the utility model are:
Lithium battery pole ear of the present utility model offers through hole by punching in the middle part of lug sheet; current-carrying part in the middle part of lug sheet is made to narrow; when causing excessive electric current by lug sheet due to short circuit, lug sheet can fuse in time in the part of through hole dual-side, plays the effect of protection battery.
Accompanying drawing explanation
It is described further below in conjunction with accompanying drawing and example.
Fig. 1 is the structural representation of a kind of preferred embodiment of the present utility model；
Fig. 2 is the structural representation of another kind of preferred embodiment of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of band that this utility model provides is crossed stream and is autotomyed the lithium battery pole ear of function, including lug sheet 1, battery core external circuit is accessed in described lug sheet 1 one end, the other end connects the negative electrode of battery, offering more than one through hole 2 by punching in the middle part of lug sheet 1, the through hole 2 in the present embodiment is circular hole.
With reference to Fig. 2, another embodiment that the present embodiment provides, its structure is essentially identical with the first embodiment of Fig. 1, and the through hole 2 that difference is in the present embodiment is rectangular opening.
Lithium battery pole ear of the present utility model offers through hole 2 by punching in the middle part of lug sheet 1; current-carrying part in the middle part of lug sheet 1 is made to narrow; when causing excessive electric current by lug sheet 1 due to short circuit, lug sheet 1 can fuse in time in the part of through hole 2 dual-side, plays the effect of protection battery.
The above, preferred embodiment the most of the present utility model, this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
