Abstract
A kind of plastic housing lithium ion battery pole component, including pole component and battery core, the pole component includes pole and the band that is flexible coupling, it is described be flexible coupling to take be provided with fusing structure, the pole includes terminal post and the connect band positioned at its lower end, and two sides of the band that is flexible coupling are provided with fusing structure, and top is solder side, two sides bottom is provided with lug connect band, and this utility model has following superiority：First, pole component and battery pole ear are connected by welding manner, and the band that is flexible coupling is connected by laser welding mode with pole, are to be welded to connect and can reduce the internal resistance of cell, stable connection；Second, the band that is flexible coupling with fusing structure, after battery short circuit, the increase of electric current moment, will can be flexible coupling band fusing so that battery core internal break, prevent battery explosion, the on fire 3rd, reduce pole volume, reduce its cost, be adapted to batch production.
Description
Technical field：
This utility model is related to field of lithium ion battery, particularly a kind of plastic housing lithium ion battery pole component.
Background technology：
As the development of lithium ion battery technology is increasingly mature, the industry such as electric automobile, UPS, energy-accumulating power station is to lithium ion
The demand of battery also gradually increases, it is ensured that the quality of lithium ion battery is particularly important.At present for lithium ion battery,
Its safety is a very important technical specification, and a difficult problem of restriction lithium ion battery development.
At present in electric battery with plastic case structure, pole is to be directly connected to structure with cell polar ear, and does not possess break protecting.
The problem of presence is：Pole is directly connected to cell polar ear can only with bolts or ultrasonic bonding connection.Bolt connection
Shortcoming it is big for connection resistance, and concordance is poor, is difficult to realize automated production.The direct supersonic welding of lug is connected on pole
On, exist and connect unstable, easily damage lug, and the high shortcoming of scrappage.
Utility model content：
In order to solve the above problems, this utility model provides a kind of plastic housing lithium ion battery pole component.
This utility model solves the technical scheme adopted by its technical problem：
A kind of plastic housing lithium ion battery pole component, including pole component and battery core, the pole component include pole and
Be flexible coupling band, it is described be flexible coupling to take be provided with fusing structure.
The pole includes terminal post and the connect band positioned at its lower end, and two sides of the band that is flexible coupling are provided with molten
Disconnected structure, top are solders side, and two sides bottom is provided with lug connect band.
The lug connect band is in reverse U-shaped.
The lug connect band is connected using laser welding with battery core.
The connect band and solder side are connected using laser welding.
There is following superiority due to adopting technical scheme as above, this utility model：
First, pole component is connected by welding manner with battery pole ear, and the band that is flexible coupling is connected by Laser Welding with pole
Mode is connect, is to be welded to connect and can be reduced the internal resistance of cell, stable connection.
Second, with fusing structure, after battery short circuit, the increase of electric current moment, the band that will can be flexible coupling fuse the band that is flexible coupling,
So that battery core internal break, battery explosion, on fire is prevented.
3rd, reduce pole volume, reduce its cost, be adapted to batch production.
Meet the insulating requirements between pole and cover plate base material, simplify design and difficulty of processing, reduce cost.

Specific embodiment：
This utility model can be explained in more detail by the following examples, open the purpose of this utility model is intended to protect
All changes and improvements in the range of shield this utility model, this utility model are not limited to the following examples；
A kind of plastic housing lithium ion battery pole component with reference to described in accompanying drawing, including pole component 1 and battery core 2, the pole
Column assembly 1 includes pole 1-1 and the band 1-2 that is flexible coupling, and the band 1-2 that is flexible coupling is provided with fusing structure 1-2-2, works as battery short circuit
Afterwards, be flexible coupling the electric current moment increase of band by 1-2, and 1-2-2 fusing structures play a role, by 1-1 poles and the disconnection of 2 battery cores,
So as to reach protective effect.
The pole 1-1 includes terminal post 1-1-1 and connect band 1-1-2 positioned at its lower end, the band 1-2 that is flexible coupling
Two sides be provided with fusing structure 1-2-2, fusing structure 1-2-2 is a rectangular hole, is opened in and is flexible coupling with 1-2 two
On individual side wall, top is solder side 1-2-1, and two sides bottom is provided with lug connect band 1-2-3.
Lug connect band 1-2-3 is in reverse U-shaped, and when welding with battery core pole youngster, contact area is bigger, so as to
That what is welded is more firm, connects more stable.
Lug connect band 1-2-3 is connected using laser welding with battery core 2.
Connect band 1-1-2 and solder side 1-2-1 are connected using laser welding.
Part is not carefully stated in above content for prior art, therefore is not run business into particular one and is stated.
