Abstract
The utility model relates to the structure manufacturing technical field of a lithium secondary battery, particularly to a lithium encapsulating structure. An electrode tab arranged on the end surface in the core width direction of a electrical core is connected with a protecting sheet arranged on the side wall in the length direction of the electrical core through an adapting nickel piece; a rubber frame is connected with the peripheral wall of the electrical core; the rubber frame is connected with an output head cover which is externally connected with and arranged on the protecting sheet. Since the electrode tab of the electrical core is connected to the side surface of the electrical core for outputting through the adapting nickel piece, the utility model has the advantages of simple encapsulating structure and low manufacturing cost. The electrical core in the structure not only adopts the regular electrical core, but also is applicable to the encapsulation of the electrical core which has an anode on one end and a cathode on the other end. The structure enables an encapsulated battery to have diversified output terminals so as to reduce the design difficulty of a mobile phone.
Description
Technical field
The utility model relates to the structure manufacturing technology field of lithium secondary battery.
Background technology
Along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and makes lithium battery by all trades and professions extensive use.Lithium ion battery is mainly used on the digital products such as mobile phone, notebook computer, Digital Video, digital camera at present.Nearly one or two years,, had higher requirement in the aspects such as encapsulation of capacity, charge-discharge performance and the battery battery core of lithium battery along with the develop rapidly of mechanics of communication.Not only required to have bigger capacity, but also be limited in certain battery volume range.At above-mentioned requirements, each battery production factory has also taked various ways, but main battery battery core of still how packing in inside as much as possible under with identical battery volume situation improves aspect this, and promptly the encapsulating structure to battery improves.
The disclosed various encapsulating structures of prior art mainly are the situations at the positive and negative electrodes in same end.And because the design of mobile phone makes the lead-out terminal that is applied to the battery on the mobile phone not lay down hard and fast rule, the outgoing position of battery may appear at the Width that electric core length direction also may appear at electric core.Disclosed battery component in No. 200610073939.6 application for a patent for invention specifications of China, it discloses the battery component of exporting in the encapsulation output of battery length direction and the encapsulation of cell widths direction, draws the electric core that two kinds of specifications of lug are drawn in lug and electric core side but need in this application to adopt at electric core head.Just just need employing and draw the manufacturing cost that the electric core of lug has improved battery so undoubtedly in the side in the output of battery side.
The utility model content
Technical problem to be solved in the utility model provides a kind of use common electrical core, and is especially positive and negative
The electric core of utmost point heterodoxy encapsulates makes battery to be implemented in the lithium battery encapsulating structure of battery side length direction output.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Design a kind of lithium battery encapsulating structure; lug on the electricity core Width end face is connected with baffle on being arranged on electric core length direction sidewall by switching nickel sheet; be connected with the glue frame on the described electric core perisporium, the output skull that is provided with on described glue frame and the baffle is connected.
As the improvement of such scheme, the design of glue frame is " ㄇ " shape, and the electric core of this programme can be the electric core of both positive and negative polarity heterodoxy.Above-mentioned output skull can be that the low-pressure injection molding mode is connected with electric core and glue frame, also can be to adopt bonding mode that the output skull of injection formed in advance is connected with electric core and glue frame.
The utility model has following remarkable result compared to existing technology:
The utility model is transferred to the output of electric core side to cell polar ear by switching nickel sheet, and encapsulating structure is simple, low cost of manufacture.This structure electricity core not only can adopt conventional electric core, also is applicable to the electric core encapsulation of both positive and negative polarity heterodoxy.Make the variation of the battery output terminal after the encapsulation, reduced the difficulty of mobile phones design.
Description of drawings
Fig. 1 is a parts decomposing schematic representation of the present utility model;
Fig. 2 is the schematic diagram after electric core and baffle and the assembling of glue frame;
Fig. 3 is the packaged battery schematic diagram after the output skull is gone up in connection.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Referring to Fig. 1～3, a kind of lithium battery encapsulating structure, the electric core in its encapsulating structure is the electric core 1 of both positive and negative polarity heterodoxy, can certainly adopt the conventional electric core of positive and negative electrodes in same end.This encapsulating structure difference is the lug on the electric core is transferred on the adjacent electric core side encapsulation output, makes battery outgoing position variation after the encapsulation, satisfies the needs of mobile phones design.
During encapsulation, the lug on the electric core Width end face, the anode ear, the negative electrode lug that just are positioned on electric core front end face, the back are guided on the sidewall of electric core by switching nickel sheet 3 respectively.This sidewall locations place is provided with baffle 2 at electric core, has protective circuit and lead-out terminal on the baffle, and the lead-out terminal on the baffle is connected with cell polar ear by switching nickel sheet.
One of injection mo(u)lding in advance has the plastic cement frame 4 that three limits are " ㄇ " shape, and the plastic cement frame is bonded on three sidewalls of the electric core adjacent with electric core baffle, and the plastic cement frame is used to protect electric core front end face, rear end face.Electricity core, baffle and plastic cement frame assembling back are put into particular manufacturing craft to assembly together and are carried out low-pressure injection molding, connect output skull 5 by the low-pressure injection molding mode in the baffle outside.
Certainly, also the skull of injection formed output in advance is bonded and fixed at the output skull with the plastic cement frame.Wrapping trade mark 6 again outside electric core main body after the output skull is fixing gets final product.
Battery packaging structure in side output provided by the utility model adopts electric core of the same type just can realize the variation of battery output terminal, has reduced the manufacturing cost of battery for mobile phone.
