Abstract
The utility model discloses a kind of die-cut lug, the lug body comprising battery core and be connected with battery core, described lug body and battery core are for being electrically connected, described lug body comprises positive pole and negative pole, interlayer is provided with between positive pole and negative pole, described lug body is provided with positive/negative plate, positive/negative plate is provided with positive and negative lug, the afterbody of described lug body is die-cut by it by a kind of die-cut fixture, when pole piece is rolled into battery core, because of process requirements, lug need bend, lug is when bending, and the not in place of irregular or edge subsides can not pasted because of insulation gummed paper causes internal short-circuit of battery.The utility model can prevent internal short-circuit of battery, improves the fail safe that battery uses.
Description
Technical field
The utility model relates to a kind of lug, particularly the die-cut lug of one.
Background technology
Existing lithium electronic polymer battery is mainly used in the product in 3C field, and lug is indispensable raw material in lithium ion battery polymer, and existing lug is divided into, single, board-like, rolling three types.Lug is drawn by the both positive and negative polarity of battery, as connecting from outside contact point, battery in manufacturing process, need through artificial or equipment by tab welding on pole piece, need to stick insulation gummed paper with pole piece centre at the tab of lug, prevent internal short-circuit of battery.No matter be manual subsides insulation gummed paper or machine subsides insulation gummed paper, can exist and paste irregular and pole piece and tab edge pastes phenomenon not in place, if this problem occurs, as easy as rolling off a logly can cause fatefulue destruction to battery, cause the safety issue such as battery catches fire, blast.
Summary of the invention
The utility model mainly solves the technical problem existing for prior art, thus provides one to prevent internal short-circuit of battery; Improve the die-cut lug of battery safety in utilization.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of die-cut lug, the lug body comprising battery core and be connected with battery core, described lug body and battery core are for being electrically connected, described lug body comprises positive pole and negative pole, is provided with interlayer between positive pole and negative pole, and described lug body is provided with positive/negative plate, positive/negative plate is provided with positive and negative lug, and positive and negative lug is provided with gum cover.
Adopt the die-cut lug of technique scheme, because described lug body and battery core are for being electrically connected, described lug body comprises positive pole and negative pole, interlayer is provided with between positive pole and negative pole, described lug body is provided with positive/negative plate, and positive/negative plate is provided with positive and negative lug, and positive and negative lug is provided with gum cover; So prevent internal short-circuit of battery; Improve the fail safe that battery uses; Improve finished battery rate.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the die-cut lug of the utility model;
Fig. 2 is the structural representation of lug body described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
As shown in Figure 1 to Figure 2, a kind of die-cut lug, the lug body comprising battery core 6 and be connected with battery core 6, described lug body and battery core 6 are for being electrically connected, and described lug body comprises positive pole 1 and negative pole 4, is provided with interlayer 2 between positive pole 1 and negative pole 4, negative lug 3 is provided with between interlayer 2 and negative pole 4, described lug body is provided with positive/negative plate, and positive/negative plate is provided with positive and negative lug, and described lug body is coated with insulation gummed paper 5; Positive and negative lug is provided with gum cover 7.
The die-cut lug of the utility model, tab afterbody is carried out die-cut irregular the or edge pasted because of insulation gummed paper can be avoided to a great extent to paste not in placely cause internal short-circuit of battery, cause the safety problems such as battery catches fire blast, thus improve the fail safe of battery use, and the difficulty that this operation of insulation gummed paper is pasted by battery core factory can be reduced, improve the rate of finished products of battery core.
The die-cut lug of the utility model, prevents internal short-circuit of battery; Improve the fail safe that battery uses; Improve finished battery rate.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
Claims (1)
