Abstract
The invention discloses the preparation methods that a kind of lithium battery overloads self-shield lug; by carrying out special-shaped processing to metallic conductor; so that having a carrying object among metallic conductor; the function of " fuse " is served as by it; in main equipment operating overload; it can fuse automatically, to play the role of self-shield carrying object.It, can be in the case where not changing entire metallic conductor length with the slanted bar shape carrying object of formation due to by the way of opening triangular groove in metallic conductor two sides so that carrying object reaches width and length needed for fusing.
Description
Technical field
The present invention relates to foil process tools, and the preparation of self-shield lug is overloaded more specifically to a kind of lithium battery
Method.
Background technology
Common batteries lead (also known as lug, collectively termed as lug, divides positive and negative pole below, it will usually according to lug material into
Row classification, such as：Aluminium pole ears, nickel plating copper polar ear, nickel lug etc.) structure design be：Metallic conductor 1 and strip including sheet
Polymer insulating film 2, wherein polymer insulating film 2 is solid-state strip material, viscous through 140 degree~160 degree heating and metallic conductor
Knot (commonly referred to as seals).This lug is usually applied to compact electric apparatus or use for electronic products lithium battery：Such as model plane, electric tool
Deng.However, for the lithium battery of certain special-purposes, the characteristics of due to main equipment, extra high want is proposed to overload protection
It asks.So, at present existing common batteries lug can not just meet its demand well, it is necessary to carry out special structure design and
It improves.
Invention content
For disadvantages mentioned above existing in the prior art, the object of the present invention is to provide a kind of lithium battery overload self-shield poles
The preparation method of ear can have overload self-protection function.
To achieve the above object, the present invention adopts the following technical scheme that：
On the one hand, a kind of lithium battery overloads self-shield lug, including the metallic conductor of sheet and transversal heat seal are led in metal
The band-like polymer insulating film of solid-state on body, the two sides of the metallic conductor are laterally provided with a triangular groove respectively, and two or three
Chamfered groove sequence arranges that the metallic conductor between two triangular grooves forms one in the diagonally disposed current-carrying for playing overload and fusing automatically
Body.
The two triangular groove sizes are identical.
Two triangular grooves and carrying object are heat-sealed in it by the polymer insulating film.
On the other hand, a kind of preparation method of lithium battery overload self-shield lug, includes the following steps：
A. a triangular groove is laterally opened up respectively in the two sides of the metallic conductor of rectangular patch, and make two triangular groove sequences
Arrangement so that the metallic conductor between two triangular grooves forms one in the diagonally disposed carrying object for playing overload and fusing automatically；
B. by polymer insulating film transversal heat seal on metallic conductor, and two triangular grooves and carrying object are heat-sealed in it
It is interior.
In the above-mentioned technical solutions, the preparation method of lithium battery of the invention overload self-shield lug has following excellent
Point：
1, special-shaped processing is carried out to metallic conductor so that there is a carrying object among metallic conductor, " insurance is served as by it
The function of silk ", can be automatic to fuse when main equipment overloads, to play the role of self-shield carrying object.
2, by the way of opening triangular groove in metallic conductor two sides, with the slanted bar shape carrying object of formation, can not change
In the case of becoming entire metallic conductor length so that carrying object reaches width and length needed for fusing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the lug of the prior art；
Fig. 2 is the schematic cross-sectional view of a side of the lug of the prior art；
Fig. 3 is the structural schematic diagram of the lithium battery overload self-shield lug of the present invention；
Fig. 4 is the structural schematic diagram of the metallic conductor of the lug of the present invention.
Specific implementation mode
The technical solution further illustrated the present invention with reference to the accompanying drawings and examples.
It please refers to shown in Fig. 3~Fig. 4, lithium battery of the invention overload self-shield lug is same as the prior art, together
Sample also include sheet metallic conductor 1 and transversal heat seal in the band-like polymer insulating film 2 of the solid-state on metallic conductor 1.It is different
, the two sides of the metallic conductor 1 are laterally provided with a triangular groove 3, two triangular grooves, 3 sequence arrangement, two or three respectively
Metallic conductor 1 between chamfered groove 3 forms one in the diagonally disposed carrying object 4 for playing overload and fusing automatically.
As a preferred embodiment, two triangular grooves, 3 size is identical.
As another preferred embodiment, the polymer insulating film seals two triangular grooves 3 and carrying object 4
In the inner.
The preparation method of the lithium battery overload self-shield lug of the present invention, includes the following steps：
A. a triangular groove 3 is laterally opened up respectively in the two sides of the metallic conductor of rectangular patch 1, and make two triangular grooves, 3 phase
Dislocation arrangement so that the metallic conductor 1 between two triangular grooves 3 forms one in the diagonally disposed current-carrying for playing overload and fusing automatically
Body 4；
B. by 2 transversal heat seal of polymer insulating film on metallic conductor 1, and two triangular grooves 3 and carrying object 4 are sealed
In the inner.
In conclusion the lithium battery overload self-shield lug and preparation method thereof of the present invention, has the advantages that following：
1, special-shaped processing is carried out to metallic conductor 1 so that there is a carrying object 4 among metallic conductor 1, served as by it
The function of " fuse " can fuse automatically in main equipment operating overload, to play the role of self-shield carrying object 4.
It 2,, can be not with the slanted bar shape carrying object 4 of formation by the way of opening triangular groove 3 in 1 two sides of metallic conductor
In the case of changing 1 length of entire metallic conductor so that carrying object 4 reaches width and length needed for fusing.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
