Abstract
The utility model relates to the technical field of a lithium battery, in particular to the improvement of a lithium battery package structure. A bracket, a protection board and a cover are connected with the front end of an electric core of the package battery structure; the protection board is provided with an output terminator that is connected with a tab of the electric core and the cover is arranged on the front end of the electric core in the way of bonding. The cover of the package is fixed on the front end surface of the electric core through the colloid or the double-sided adhesive tape, and the cover is a trough-shaped body that is molded in advance, and a hole with the shape corresponding to that of the output terminator on the protection board face is arranged on the bottom of the trough. The bracket is a bracket body that is provided with a groove and can support the protection board, two metal sheets drawn from the anode and the cathode of the electric core pass through the groove of the bracket and connect with the output terminator of the protection board. The package structure provided by the utility model can pack the electric core with the minimum space so as to reduce the volume of the packed battery, thereby enlarging the capacity of the battery. At the same time, the bracket is provided with a position-avoiding through-hole structure, which is not only firm, but also can reduce the volume of the battery after the package.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to the improvement of lithium battery encapsulating structure.
Background technology
Along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and causes lithium battery by all trades and professions extensive use.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.
For the encapsulation key technology of battery battery core be cell polar ear with external terminal between be connected with and insulation-encapsulated.The encapsulation of present electric core is to make the form of sealing by injection moulding again after the welding of the lead-out terminal on cell polar ear and the baffle electric core, baffle constitute integral body mostly.
In the disclosed encapsulating structure of China's CN02140207.8 patent " packaged battery and manufacture method thereof ", be printed circuit pole piece and battery components such as shaped bracket and battery, be assembled into together in the forming room of mould and will form resin-molded component behind the mould matched moulds.Resin-molded component is that the battery output terminal and the shaped bracket that are used for being fixed in printed substrate couple together.The encapsulating structure of this patent disclosure, the resin-molded component of its shaped as frame need be put into mold injection to the entire cell assembly and form, structure relative complex, cost height.
The utility model content
Problem to be solved in the utility model provides a kind of production efficiency height, technology simple package battery structure.
For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:
Design a kind of lithium battery encapsulating structure, comprise battery battery core, electric core front end is connected with support, baffle and cover, and the lead-out terminal that is connected with cell polar ear is arranged on the baffle, and cover is placed on electric core front end by bonding mode.
The encapsulation cover be fixed on the electric core front end surface by colloid or double faced adhesive tape, cover be in advance the shaping groove shape body, bottom land be provided with the baffle face on the corresponding hole of lead-out terminal shape.Support is the support body with supported baffle of groove, and the positive and negative electrode of electric core is drawn sheet metal and passed rack groove and be connected with lead-out terminal on the baffle.
The utility model compared with prior art has following advantage:
Encapsulating structure provided by the utility model, cover is fixedly coupled mode with glue, can encapsulate electric core with the space of minimum, reduces to encapsulate the back volume of battery, thereby can increase the capacity of battery.Face shield and support are shaped in advance and are convenient to produce in batches and improved working (machining) efficiency.The while support has keeps away a through-hole structure, not only firm, also can reduce to encapsulate the back volume of battery.
Description of drawings
Fig. 1 is the exploded perspective view of utility model; Fig. 2 is the schematic diagram of Fig. 1 medium-height trestle;
Fig. 3 is the utility model appearance assumption diagram.
Specific embodiments
The utility model is described in further detail below by specific embodiment:
Referring to Fig. 1-3, a kind of lithium battery encapsulating structure comprises battery battery core 8; electricity core front end is connected with support 3; support is the support body of the band groove that is shaped in advance, is used to support and be fixed with the baffle 2 of battery protecting circuit substrate, and baffle is provided with battery output terminal.
The positive pole of electricity core front end is drawn sheet metal 5 and negative pole and is drawn sheet metal 4 and can weld together from the battery output terminal that passes groove 31, be provided with baffle.The cover 1 that support, baffle and battery front end are entangled together is the groove shape body that is shaped in advance, bottom land be provided with the baffle face on the corresponding hole of lead-out terminal shape, thereby lead-out terminal is exposed from cover.And cover is by being fixed on the electric core beating glue or bonding double faced adhesive tape on the electric core, if requirement of strength is not high, cover can general trade mark be adhesively fixed.The fixed form of beating glue and double faced adhesive tape can make the space of the electric core of encapsulation dwindle.In order to protect electric core also to be bonded with bottom 11 at the tail end of electric core.
During reality processing packaged battery, elder generation sticks on insulating paper 7 or insulation film the negative pole end of electric core, be used for insulation, then PTC resettable fuse 6 and negative pole drawn sheet metal 4 and be welded in electric core negative pole as the copper sheet point, positive pole is drawn sheet metal 5 as the positive pole of nickel sheet electric welding at electric core.Again positive pole is drawn sheet metal 5 and negative pole afterwards and draw sheet metal 4 and baffle welding, thereby the both positive and negative polarity of electric core is communicated with lead-out terminal on the baffle.Between electric core and baffle, load onto support after welding is good, draw the sheet metal groove, can conveniently load onto support, make support play the effect of supporting baffle simultaneously because avoid electric core both positive and negative polarity on the support.After baffle and support install, stick double faced adhesive tape at electric wicking surface and make firm being bonded on the electric core of cover.Bondd behind the cover, passed through bottom 11 on double faced adhesive tape 10 bondings at electric core tail end.Cover, the packaged back of bottom install packing paper 9 additional in electric core both sides, at last parcel trade mark 12 on electric core.The packing paper of electricity core both sides can make electric core both sides and cover, bottom concordant, the trade mark fold of electric core side when preventing to wrap up trade mark.
