Abstract
Lug with safe fuse function, including lug ontology are provided with spaced apart fusing hole on the lug ontology, and the position that fusing hole is provided on the lug ontology is provided with gel.The utility model on lug ontology by processing fusing hole, make lug while normally carrying rated current, it can fuse in time in short circuit, it can prevent from generating harm safely to battery core because of external short circuit, and gel can also carry out position holding to the part after fusing, the secondary contact of lug after fusing is prevented, the security performance of battery core is further enhanced.
Description
Technical field
The utility model belongs to technical field of lithium ion, more specifically to a kind of Soft Roll polymer Li-ion
The lug of battery.
Background technology
From the point of view of the development in domestic and international lithium battery market, the market share of Soft Roll polymer Li-ion battery is constantly carrying
It rises, the safety of lithium ion battery also receives more and more attention.For soft bag lithium ionic cell because its capacity is big, electric current is big, right
Higher requirements are also raised for the safety of battery core, module and whole packet.Although battery management system (BATTERY can be passed through
MANAGEMENT SYSTEM, abbreviation BMS) realize overcurrent protection and the function that overtemperature powers off, but the above measure is primarily directed to electricity
The salvo that pond module or integral battery packet are taken.For single battery core, presently mainly by welding fuse
(fuse) or breaker (breaker) is to improve the security performance of battery core, but needs occupancy additional space with upper type, and
Material cost is high.
Utility model content
The purpose of this utility model is to provide a kind of lug with safe fuse function simple in structure, at low cost, can
Prevent leakage caused by battery core short circuit, on fire, explosion equivalent risk.
To achieve the goals above, the utility model takes following technical solution：
Lug with safe fuse function, including lug ontology are provided on the lug ontology spaced apart molten
Disconnected hole, the position that fusing hole is provided on the lug ontology are provided with gel.
Further, it is external to be wrapped in the lug sheet for the gel.
Further, the fusing hole is completely covered in the gel.
Further, the fusing hole is waist-shaped hole or circular hole or square hole.
Further, it is provided with row's fusing hole on the lug ontology.
Further, multiple rows of fusing hole is provided on the lug ontology, row's fusing hole and another row's fusing hole are mutual
Dislocation arrangement.
By above technical scheme it is found that the utility model makes lug have class by processing fusing hole on lug ontology
It is similar to the function of " fuse ", the part between fusing hole has certain conveyance capacity, not only can normally carry rated current,
And can fuse in time in short circuit, so that lug itself is had safe fuse function, can prevent because external short circuit is to battery core
Safety generates harm, and position can be fixed to the lug ontology after fusing in gel, prevents the part of fusing is secondary from connecing
Touching leads to short circuit, further enhances the security performance of battery core.The utility model is relative to traditional welding breaker's or fuse
Mode not only saves space, alleviates lug weight, and save material, reduces cost.
Description of the drawings
It, below will be to required in embodiment or description of the prior art in order to illustrate more clearly of the utility model embodiment
The attached drawing used does simple introduction, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model embodiment 1；
Fig. 2 is the structural schematic diagram of the utility model embodiment 2.
Specific embodiment of the present utility model is described in more detail below in conjunction with attached drawing.
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings, when the utility model embodiment is described in detail, for ease of
Illustrate, indicates that the attached drawing of device architecture can disobey general proportion and do partial enlargement, and the schematic diagram is example, herein
The range of the utility model protection should not be limited.It should be noted that attached drawing is using simplified form and uses non-accurate
Ratio, only to purpose that is convenient, clearly aiding in illustrating the utility model embodiment.
Embodiment 1
As shown in Figure 1, the lug of the present embodiment includes lug ontology 1, several interval settings are machined on lug ontology 1
Fusing hole 1a.There is spacing between adjacent fusing hole 1a, the side of fusing hole 1a on the outermost side and lug ontology 1 it
Between also have spacing.The fusing hole 1a of the present embodiment is waist-shaped hole.By the way that fusing hole 1a is arranged on lug ontology 1, work as battery core
When short-circuit, lug ontology 1 can in time fuse at the position for being provided with fusing hole 1a, to avoid short circuit that battery core is caused to leak
Liquid, it is on fire, explosion etc. harm, while can also meet rated current and peak point current by the needs of.
Gel 2 is enclosed on lug ontology 1, gel 2 is wrapped in the position that fusing hole 1a is provided on lug ontology 1
It sets.Fusing hole 1a is completely covered in gel 2 in the present embodiment.By wrapping up gel, the stretching that can increase lug ontology is strong
On the other hand degree wraps up gel in the position for being machined with fusing hole, after lug ontology fuses, gel still can be to fusing
Two parts lug ontology is fixed, and makes to maintain a certain distance between two parts lug ontology of fusing, avoids leading because of vibration
Cause the part to have fused that second of contact occurs and brings safety problem.
Embodiment 2
As shown in Fig. 2, the present embodiment place different from embodiment 1 is：The shape of fusing hole 1a is circle, in lug
The fusing hole 1a of three misarrangement positions arrangement is provided on ontology 1.Gel 2 covers the region that part is provided with fusing hole 1a, not
All fusing hole 1a are completely covered.
The lug ontology of the utility model can be used aluminium, nickel and its alloy and be made.The shape packet of fusing hole on lug ontology
Include but be not limited to circle, rectangle etc..
Above example is only to illustrate the technical solution of the utility model rather than its limitations, although with reference to above-mentioned implementation
The utility model is described in detail in example, it should be understood by a person of ordinary skill in the art that still can be to this reality
It is modified or replaced equivalently with novel specific implementation mode, and is repaiied without departing from any of the spirit and scope of the utility model
Change or equivalent replacement, should all cover among the scope of the utility model.
