Abstract
The utility model relates to one can ultrasonic bonding simple explosion-proof combined hat, comprise steel cap, burst disk and sealing ring, described steel cap is arranged on above burst disk, described sealing ring is coated on the excircle of steel cap and burst disk, groove is had in the middle of described burst disk, described groove floor surrounding is provided with impression, and described burst disk and lug pass through ultra-sonic welded.The beneficial effects of the utility model are: combined hat has explosion prevention function, security incident when can effectively prevent battery abnormal; Burst disk is fixedly connected with by ultra-sonic welded with lug, improves welding yield, and makes client that ultrasonic welding machine can be used to substitute laser-beam welding machine, reduces the equipment investment of client.
Description
Technical field
The utility model relates to technical field of lithium batteries, and especially one can ultrasonic bonding simple explosion-proof combined hat.
Background technology
Lithium battery is a class is negative material, the battery using non-aqueous electrolytic solution by lithium metal or lithium alloy.The lithium battery occurred the earliest comes from great inventor Edison, uses following reaction: this reaction of Li+MnO2=LiMnO2 is redox reaction, electric discharge.Because the chemical characteristic of lithium metal is very active, make the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium battery is not applied for a long time.Along with the development of science and technology, present lithium battery becomes main flow.
Along with the development of twentieth century microelectric technique, miniaturized equipment is increasing, proposes very high requirement to power supply.Lithium battery enters the large-scale practical stage thereupon.What applied the earliest is the sub-primary cell of lithium, in cardiac pacemaker.Because the self-discharge rate of the sub-battery of lithium is extremely low, discharge voltage is very mild.Pacemaker implantation human body Long-Time Service is made to become possibility.Lithium-manganese cell generally has the nominal voltage higher than 3.0 volts, is more suitable for making ic power, is widely used in computer, calculator, wrist-watch.Lithium ion battery is widely applied on mobile phone, notebook computer, electric tool, electric motor car, street lamp stand-by power supply, boat lamp, family expenses small electric apparatus, can be described as maximum application group.
Now domestic lithium electricity application is more and more wider, and low capacity low cost lithium battery starts a large amount of listing.And common combined hat is due to complex manufacturing, cost is higher, and the combined hat of some low cost does not have explosion prevention function, and some has explosion-proof but cannot ultrasonic bonding lug.
Utility model content
The technical problems to be solved in the utility model is: in order to solve common combined hat due to complex manufacturing, cost is higher, low cost combined hat does not have explosion prevention function, and some has explosion-proof but cannot the problem of ultrasonic bonding lug, provides one can ultrasonic bonding simple explosion-proof combined hat.
The utility model solves the technical scheme that its technical problem adopts: one can ultrasonic bonding simple explosion-proof combined hat, comprise steel cap, burst disk and sealing ring, described steel cap is arranged on above burst disk, described sealing ring is coated on the excircle of steel cap and burst disk, groove is had in the middle of described burst disk, described groove floor surrounding is provided with impression, and described burst disk is fixedly connected with by ultra-sonic welded with lug.
As preferably, the material of described steel cap is the carbon steel of plating nickel on surface.
As preferably, the material of described burst disk is fine aluminium.
As preferably, the material of described sealing ring is polypropylene.
As preferably, the material of described burst disk is the aluminium strip that 0.5mm is thick.
The beneficial effects of the utility model are: combined hat has explosion prevention function, security incident when can effectively prevent battery abnormal; Lug can pass through ultrasonic bonding with block, improves welding yield, and makes client that ultrasonic welding machine can be used to substitute laser-beam welding machine, reduce the equipment investment of client.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of burst disk in the utility model;
Fig. 3 is the structural representation of sealing ring in the utility model.
In figure: 1. steel cap, 2. burst disk, 3. sealing ring, 4. box hat, 5. groove, 6. impression.
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.
One as shown in Figure 1 can ultrasonic bonding simple explosion-proof combined hat, comprise steel cap 1 that material is plating nickel on surface carbon steel, burst disk 2 that material is as shown in Figure 2 fine aluminium and material be as shown in Figure 3 polyacrylic sealing ring 3, steel cap 1 is arranged on above burst disk 2, sealing ring 3 is coated on the excircle of steel cap 1 and burst disk 2, groove 5 is had in the middle of described burst disk 2, described groove 5 bottom surface surrounding is provided with impression 6, and burst disk 2 is fixedly connected with by ultra-sonic welded with lug.
Burst disk 2 adopts the thick aluminium strip punching press of 0.5mm, middle ironed, and then extrude indentation explosion-proof, burst disk 2 bulk strength can meet ultrasonic bonding requirement; Steel cap 1, together with burst disk 2 laser welding, can well reduce contact resistance.
When normal battery operation, low resistance consumption can be ensured, powerful through-current capability.When battery occurs abnormal, groove 5 impression 6 place of burst disk 2 is thinner, breaks in time to release inner pressure of battery, reliably effectively plays the safety protection function of explosion-proof combined block.
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.
