Abstract
The invention discloses a lithium battery tab with an overcurrent automatic-fusing function. The lithium battery tab comprises a tab piece, wherein one end of the tab piece is connected to a cell external circuit while the other end of the tab piece is connected with a battery tab; and a through hole is formed in the middle of the tab piece in a punching manner. According to the lithium battery tab, the through hole is formed in the middle of the tab piece in the punching manner, so that a conductive part in the middle of the tab piece is thinned; and when overhigh current passes through the tab piece caused by short circuit, the parts on the two sides of the through hole can be fused in time so as to protect the battery.
Description
Technical field
The present invention relates to field of lithium, particularly relate to a kind of lithium battery pole ear of function of autotomying with overcurrent.
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 can protect inside battery not by the impact of external short circuit circuit, play the effect of protection battery.But the lug of existing lithium battery is generally served as by the strip-shaped conductive bar that width is identical, not easily fuses when short circuit appears in circuit, the effect of protection battery cannot be played.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of lithium battery pole ear of function of autotomying with overcurrent.
The present invention is the technical scheme solving the employing of its technical problem:
A lithium battery pole ear for function of autotomying with overcurrent, comprises lug sheet, and described lug sheet one end access battery core external circuit, the other end connects battery electrode, offers through hole in the middle part of lug sheet by punching.
As the further improvement of technique scheme, described lug sheet offers more than one through hole.
As the further improvement of technique scheme, the shape of described through hole is circular or rectangle or square.
As the further improvement of technique scheme, described lug sheet connects battery negative electrodes.
The invention has the beneficial effects as follows:
Lithium battery pole ear of the present invention offers through hole by punching in the middle part of lug sheet; in the middle part of making lug sheet, current-carrying part narrows; 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
Be described further below in conjunction with accompanying drawing and example.
Fig. 1 is the structural representation of a preferred embodiment of the present invention;
Fig. 2 is the structural representation of another kind of preferred embodiment of the present invention.
Embodiment
With reference to Fig. 1, the lithium battery pole ear of a kind of function of autotomying with overcurrent provided by the invention, comprise lug sheet 1, described lug sheet 1 one end access battery core external circuit, the other end connects the negative electrode of battery, offer 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 substantially identical with first embodiment of Fig. 1, and difference is that the through hole 2 in the present embodiment is rectangular opening.
Lithium battery pole ear of the present invention offers through hole 2 by punching in the middle part of lug sheet 1; in the middle part of making lug sheet 1, current-carrying part narrows; 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, just preferred embodiment of the present invention, the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
