Abstract
The utility model relates to cylinder box hat technical field of lithium batteries, especially a kind of combined hat being convenient to laser welding, comprise steel cap, burst disk and sealing ring, steel cap is positioned at the top of burst disk, sealing ring is coated with burst disk, the bottom of sealing ring and the bottom of burst disk are in same level, and burst disk is wrapped in steel cap and welds together.The combined hat being convenient to laser welding of the present utility model, concordant with the bottom of sealing ring by arranging burst disk, facilitate the welding of lug, improve efficiency and the yield of tab welding.Combined hat has explosion prevention function, when normal battery operation, can ensure low resistance consumption, powerful through-current capability; When battery occurs abnormal, burst disk can be broken in time and be laid down inner pressure of battery, effectively can play the safety protection function of combined hat.
Description
Technical field
The utility model relates to cylinder box hat technical field of lithium batteries, especially a kind of combined hat being convenient to laser welding.
Background technology
Now domestic lithium battery applications is more and more extensive, and low capacity low cost lithium battery starts a large amount of listing, and the combined hat that this type of battery uses generally does not connect aluminium flake, explosion-proof aluminium flake is plane, need lug to go deep in sealing ring during laser welding of lug, cause welding difficulty comparatively large, yield is on the low side.
Utility model content
The technical problems to be solved in the utility model is: in order to need to go deep in sealing ring by lug when solving laser welding of lug, and cause welding difficulty comparatively large, the problem that yield is on the low side, now provides a kind of combined hat being convenient to laser welding.
The utility model solves the technical scheme that its technical problem adopts: a kind of combined hat being convenient to laser welding, comprise steel cap, burst disk and sealing ring, described steel cap is positioned at the top of burst disk, described sealing ring is coated with the side of steel cap and the side of burst disk respectively, described burst disk inner chamber is hierarchic structure, comprise the first ladder and second ladder of ecto-entad distribution, described first ladder is wider than the second ladder, the edge of the edge fold inward cladding steel cap of described first ladder, do not need lug to go deep in sealing ring when soldering polar ear, improve efficiency and the yield of tab welding.
In order to reduce contact resistance further, the edge of described steel cap with burst disk for welding.
Preferably, the material of described burst disk is fine aluminium.
Preferably, the material stating steel cap is the carbon steel of plating nickel on surface.
Preferably, the material of described sealing ring is polypropylene.
The beneficial effects of the utility model are: the combined hat being convenient to laser welding of the present utility model, concordant with the bottom of sealing ring by arranging burst disk, facilitate the welding of lug, improve efficiency and the yield of tab welding.Combined hat has explosion prevention function, when normal battery operation, can ensure low resistance consumption, powerful through-current capability; When battery occurs abnormal, burst disk can be broken in time and be laid down inner pressure of battery, effectively can play the safety protection function of combined hat.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is combined hat schematic diagram of the present utility model;
Fig. 2 is the structural representation of burst disk;
Fig. 3 is ring structure schematic diagram;
Fig. 4 is the schematic diagram that combined hat is used on lithium battery.
In figure: 1, steel cap, 2, burst disk, 3, sealing ring, 4, box hat, 5, first step, 6, second step.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
A kind of combined hat being convenient to laser welding as shown in Figure 1,2 and 3, comprise steel cap 1, burst disk 2 and sealing ring 3, the material of burst disk 2 is fine aluminium, the material of steel cap 1 is the carbon steel of plating nickel on surface, the material of sealing ring 3 is polypropylene, steel cap 1 is positioned at the top of burst disk 2, sealing ring 3 is coated with burst disk 2, burst disk 2 inner chamber is hierarchic structure, comprise the first ladder 5 and the second ladder 6 of ecto-entad distribution, first ladder 5 is wider than the edge of the edge fold inward cladding steel cap 1 of the second ladder 6, first ladder 5, and edge and the burst disk 2 of steel cap 1 weld together.
As shown in Figure 4, when laser welding of lug, lug is put on the outer bottom of burst disk 2, carries out laser welding; Combined hat puts into box hat 4, when normal battery operation, can ensure low resistance consumption, powerful through-current capability; When battery occurs abnormal, burst disk 2 can be broken in time and be laid down inner pressure of battery.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
