Description
Technical field
The utility model relates to technical field of lithium batteries more particularly to a kind of gaskets of integrated design and insulation elastic slice.
Background technique
As non-renewable resources-petroleum resources are increasingly reduced and the pollution of environment is increasingly serious, environment is protected, energy conservation subtracts
Lined up the trend in the current world, in recent years, the exploitation of new energy is increasing, especially with battery be main power source or
The electric vehicle of the partial power energy is increasing, and ternary battery is by its capacity height, cyclical stability in power source battery
Well, the advantages that moderate cost, consequence is gradually occupied in power battery industry, wherein the rectangular aluminum-shell battery of ternary occupies
Main status, the security capabilities of the rectangular aluminum-shell battery of ternary, which improves, relies on material, design, processing procedure etc., to ternary square aluminum
The design of housing battery cover board is it is also proposed that higher requirement.
Lithium ion battery cover board as an accessory in lithium ion battery, be one kind have high temperature resistant, high-insulativity and
The battery cap system of excellent safe performance, in rectangular aluminum-shell battery, butterfly welding technology can the side's of effectively improving housing battery sky
Between utilization rate, to improve battery capacity；Butterfly welds operating process, and positive gasket is equipped with fuse, finally needs the elastic slice that will insulate
It is welded to above fuse, plays the role of security protection；Currently, the insulation elastic slice and positive gasket that produce and use are that separate type is set
Gasket, is usually first welded in core, then positive elastic slice is soldered on gasket by meter, this process increases core circulation journey
Sequence increases the risk that core scratch is scrapped, and this separation design increases the complex of processing procedure, reduces production electricity
Pond efficiency and first-pass yield；And the elastic slice size that insulate is smaller, is not easy to operate in welding process, there is insulation elastic slice welding and omits
Situation is unfavorable for improving the consistency of battery production, to influence battery security.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of gasket of integrated design and insulation
Elastic slice.
The utility model proposes a kind of integrated design gasket and insulation elastic slice, including gasket, fuse and insulation elastic slice；
Gasket includes first connecting portion and second connecting portion, and first connecting portion is connected with second connecting portion by fuse, insulation elastic slice with
Gasket is fixedly connected.
Preferably, insulation elastic slice is fixedly connected with first connecting portion.
Preferably, insulation elastic slice is fixedly connected with second connecting portion.
Preferably, insulation elastic slice one end is fixedly connected with first connecting portion, and the other end is fixedly connected with second connecting portion.
Preferably, insulation elastic slice is located at fuse side.
Preferably, first connecting portion is rectangle tabular structure.
Preferably, second connecting portion is square plate structure.
Preferably, plane where first connecting portion and second connecting portion place plane are in the same plane.
Preferably, the rectangular area is greater than the area of the square.
In the utility model, the gasket and insulation elastic slice of the integrated design proposed, before gasket and core welding just
Insulation elastic slice is fixedly connected with gasket, then the gasket for being fixed with insulation elastic slice is welded with core, to avoid inciting somebody to action
After gasket and core welding, leakage will insulation elastic slice and gasket the phenomenon that welding, while the production efficiency of lithium battery also improved.
Detailed description of the invention
Fig. 1 be the utility model proposes gasket top view；
Fig. 2 be the utility model proposes insulation elastic slice connect with gasket after top view；
Fig. 3 be the utility model proposes insulation elastic slice connect with gasket after side view.
Specific embodiment
As shown in Figure 1-3, Fig. 1 be the utility model proposes 1 top view of gasket, Fig. 2 be the utility model proposes it is exhausted
Edge elastic slice 3 connect with gasket 1 after top view, Fig. 3 be the utility model proposes insulation elastic slice 3 connect with gasket 1 after side
View.
Referring to Fig.1-3, the utility model proposes a kind of integrated design gasket and insulation elastic slice, including gasket 1, fuse
2 and insulation elastic slice 3；Gasket 1 includes first connecting portion 11 and second connecting portion 12, and first connecting portion 11 and second connecting portion 12 are logical
The connection of fuse 2 is crossed, insulation 3 one end of elastic slice is fixedly connected with first connecting portion 11, and the other end is fixedly connected with second connecting portion 12,
It is covered on 2 top of fuse in the middle part of insulation elastic slice 3, plays the purpose of protection fuse 2.
In the present embodiment, first connecting portion 11 is rectangle tabular structure, and the size of first connecting portion 11 is 18*42*
0.6mm, second connecting portion 12 square plate structures, the size of second connecting portion 12 is 18*18*0.6mm, first connecting portion
12 place co-planar of 11 place planes and second connecting portion, insulation elastic slice 3 are rectangle tabular structure, the ruler for the elastic slice 3 that insulate
