Abstract
The lithium battery pole ear structure that this utility model provides includes: shell, it is fixed on multiple battery cores of enclosure, described battery core is that the internal layer winding that positive pole coating, insulating barrier and negative pole coating set gradually forms, wherein, the plurality of positive pole coating draws multiple positive plates, multiple negative pole coatings draw multiple negative plates, and multiple positive plates or multiple negative plate are connected together cathode contact or cathode contact by supersonic welding;Described cathode contact or negative pole go out a little to stretch out described shell, and are fixedly secured in the groove of lug, and described lug also has extension, and the direction that extension stretches out is vertical with groove bearing of trend.This utility model, by the way of being fixed in the groove with certain elastic lug, overcomes the technical problem that lug is easily broken off.
Description
Technical field
This utility model relates to field of batteries, particularly relates to a kind of lithium battery pole ear structure.
Background technology
Anode ear, negative plate and a conductive material is formed after the positive plate of lithium ion battery and a conductive material welding
After welding formed negative electrode lug, but the anode ear of this spline structure is poor with the fixing intensity of negative electrode lug, easily cause anode ear and
The coming off or rupture of positive plate, negative electrode lug comes off with negative plate or ruptures.
Utility model content
The technical problems to be solved in the utility model is: the fixing intensity of offer one is relatively strong, the most not electric with having of fracture
The lithium battery pole ear structure of core.
For achieving the above object, the lithium battery pole ear structure that this utility model provides includes: shell, is fixed on enclosure
Multiple battery cores, described battery core be positive pole coating, insulating barrier and negative pole coating set gradually internal layer winding form, wherein,
The plurality of positive pole coating draws multiple positive plates, and multiple negative pole coatings draw multiple negative plates, multiple positive plates or multiple negative
Pole piece is connected together cathode contact or cathode contact by supersonic welding;Described cathode contact or negative pole go out a little stretch out described outside
Shell, and be fixedly secured in the groove of lug, described lug also has extension, the direction that extension stretches out and groove extension side
To vertically.
Further, described lug is for having resilient conductive material.
Further, the lateral wall of described groove is fixed on shell by a fixture fastening, described fixture
For insulant.
Further, described fixture is L-shaped structure.
Further, one side of described groove is fixed with extension, and another side pushes against and be fixed on the upper of shell
Surface.
Lithium battery of the present utility model has multiple battery core, and multiple positive plates or the negative plate multiple battery cores drawn lead to
Cross the mode being fixed in the groove with certain elastic lug, overcome the technical problem that lug is easily broken off, product quality
Preferably, service life and the yields of lithium battery can be improved.

Detailed description of the invention
By further illustrating the technological means and effect thereof that this utility model taked, below in conjunction with of the present utility model
Preferred embodiment and accompanying drawing thereof are described in detail.
Referring to Fig. 1 or Fig. 2, the lithium battery pole ear structure that this utility model provides includes: shell 100, is fixed on shell
Multiple battery cores 200 within 100, described battery core 200 is that positive pole coating 210, insulating barrier 220 and negative pole coating 230 set successively
The internal layer winding put forms, and wherein, the plurality of positive pole coating 210 draws multiple positive plate 201, and multiple negative pole coatings are drawn many
Individual negative plate, multiple positive plates 201 or multiple negative plate are connected together cathode contact 202 or cathode contact by supersonic welding;
Described cathode contact 202 or negative pole go out a little to stretch out described shell 100, and are fixedly secured in the groove 310 of lug 300, described
Lug 300 also has extension 320, and the direction that extension 320 stretches out is vertical with groove 310 bearing of trend.
In the present embodiment, after multiple cathode contacts 202 or cathode contact are welded, it is plugged in groove 310, a side
Face can increase the fixing intensity of cathode contact 202 or cathode contact and lug 300, prevents fracture;On the other hand pass through
The mode that multiple battery cores are in parallel, expands the battery capacity of lithium battery.
Further, described lug 300 is for having resilient conductive material.
In the present embodiment, described lug 300 has elasticity, can overcome most extension 320 stress deformation
The problem of lug 300 fracture caused.
Further, the lateral wall of described groove 310 is fixed on shell 100 by fixture 400 fastening, institute
State fixture 400 for insulant.Wherein fixture further adds the fixing intensity of lug 300.
Further, described fixture 400 is L-shaped structure.Common L-shaped structure is fairly simple, it is easy to manufactures and fixes.
Further, 310 1 sides of described groove are fixed, outside another side pushes against and is fixed on extension 320
The upper surface of shell 100.
Wherein, another side of groove 310 is pushed against on the upper surface of shell 100 and further adds lug 300
Fixing intensity.
The above, for the person of ordinary skill of the art, can according to the technical solution of the utility model and
Other various corresponding changes and deformation are made in technology design, and all these change and deformation all should belong to this utility model power
The protection domain that profit requires.
