Abstract
The invention discloses an overload self-protection tabs for a lithium battery and a preparation method thereof. Through carrying out abnormity treatment on a metal conductor, a flow carrier is arranged in the middle of the metal conductor, and the flow carrier is served as a fuse, so that when a master device has running overload, the flow carrier can be automatically fused to play a self-protection effect. By adopting the slanted bar flow carrier formed through a way of opening triangular grooves in two sides of the metal conductor, the flow carrier can reach the width and the length which are needed by fusion without changing the length of the whole metal conductor.
Description
Technical field
The present invention relates to foil process tool, more particularly, it relates to a kind of lithium battery overload self-shield lug and preparation method thereof.
Background technology
Common batteries lead-in wire (has another name called lug; below it is collectively termed as lug; divide positive and negative pole; would generally classify according to lug material; such as aluminium pole ears, nickel-clad copper lug, nickel lug etc.) structural design be: include the metallic conductor 1 of lamellar and the polymer insulating film 2 of strip; wherein, polymer insulating film 2 is solid-state strip material, through 140 degree～160 degree heating and metallic conductor bonding (commonly referred to as heat-sealing).This lug is commonly used to compact electric apparatus or use for electronic products lithium battery: such as model plane, electric tool etc..But, for the lithium battery of some special-purpose, due to main equipment, overload protection is proposed extra high requirement.So, current existing common batteries lug just cannot well meet its demand, it is necessary to carries out special structural design and improvement.
Summary of the invention
For the disadvantages mentioned above existed in prior art, it is an object of the invention to provide a kind of lithium battery overload self-shield lug and preparation method thereof, it is possible to there is overload self-protection function.
For achieving the above object, the present invention adopts the following technical scheme that
On the one hand; a kind of lithium battery overload self-shield lug; polymer insulating film including the metallic conductor of lamellar and transversal heat seal solid-state banding on metallic conductor; the dual-side of described metallic conductor laterally has a triangular groove respectively; two triangular groove sequences are arranged, the metallic conductor between two triangular grooves forms one in the diagonally disposed carrying object playing overload fusing automatically.
Two described triangular groove sizes are identical.
Two triangular grooves and carrying object are all heat-sealed in it by described polymer insulating film.
On the other hand, the preparation method of a kind of lithium battery overload self-shield lug, comprise the following steps:
A. laterally offer a triangular groove respectively at the dual-side of the metallic conductor of rectangular patch, and make two triangular groove sequences arrange so that the metallic conductor between two triangular grooves forms one in the diagonally disposed carrying object playing overload fusing automatically；
B. by polymer insulating film transversal heat seal on metallic conductor, and two triangular grooves and carrying object are all heat-sealed in it.
In technique scheme, lithium battery overload self-shield lug of the present invention and preparation method thereof has several advantages that
1, metallic conductor is carried out special-shaped process so that there is in the middle of metallic conductor a carrying object, serve as the function of " electric fuse " by it, it is possible to when main equipment transships, automatically fuse, thus playing self-shield effect carrying object.
2, the mode opening triangular groove at metallic conductor dual-side is adopted, with the slanted bar shape carrying object formed, it is possible to when not changing whole metallic conductor length so that carrying object reaches the required width of fusing and length.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lug of prior art；
Fig. 2 is the cross-sectional schematic of a side of the lug of prior art；
Fig. 3 is the structural representation of the lithium battery overload self-shield lug of the present invention；
Fig. 4 is the structural representation of the metallic conductor of the lug of the present invention.
Detailed description of the invention
Technical scheme is further illustrated below in conjunction with drawings and Examples.
Referring to shown in Fig. 3～Fig. 4, the lithium battery overload self-shield lug of the present invention is same as the prior art, equally also includes the metallic conductor 1 of lamellar and the polymer insulating film 2 of transversal heat seal solid-state banding on metallic conductor 1.The difference is that, the dual-side of described metallic conductor 1 laterally has a triangular groove 3 respectively, and two triangular groove 3 sequences are arranged, the metallic conductor 1 between two triangular grooves 3 forms one in the diagonally disposed carrying object 4 playing overload fusing automatically.
As a preferred embodiment, two described triangular groove 3 sizes are identical.
As another preferred embodiment, two triangular grooves 3 and carrying object 4 are all heat-sealed in it by described polymer insulating film.
The preparation method of the lithium battery overload self-shield lug of the present invention, comprises the following steps:
A. laterally offer a triangular groove 3 respectively at the dual-side of the metallic conductor 1 of rectangular patch, and make two triangular groove 3 sequences arrange so that the metallic conductor 1 between two triangular grooves 3 forms one in the diagonally disposed carrying object 4 playing overload fusing automatically；
B. by polymer insulating film 2 transversal heat seal on metallic conductor 1, and two triangular grooves 3 and carrying object 4 are all heat-sealed in it.
In sum, lithium battery overload self-shield lug of the present invention and preparation method thereof, have several advantages that
1, metallic conductor 1 is carried out special-shaped process so that in the middle of metallic conductor 1, there is a carrying object 4, serving as the function of " electric fuse " by it, when main equipment operating overload, it is possible to automatically fuse, thus playing self-shield effect carrying object 4.
2, the mode opening triangular groove 3 at metallic conductor 1 dual-side is adopted, with the slanted bar shape carrying object 4 formed, it is possible to when not changing whole metallic conductor 1 length so that carrying object 4 reaches the required width of fusing and length.
Those of ordinary skill in the art will be appreciated that, above embodiments is intended merely to the explanation present invention, and it is not used as limitation of the invention, as long as in the spirit of the present invention, to the change of embodiment described above, modification all by the Claims scope dropping on the present invention.
