Liquid lithium ionic cell is widely used in communication, electron trade as a kind of high efficient energy sources carrier, particularly on person-to-person communication such as mobile phone, the PDA instrument.Nearly one or two years, along with the develop rapidly of mechanics of communication, mobile phone color screen technology, multimedia message technology, Bluetooth technology and camera technique are continuous mutually to be occurred, and indexs such as the capacity of liquid towards lithium battery, volume, weight and chemical property are had higher requirement.
The electric core of existing lithium battery generally adopts takeup type core strueture and lamination type electric cored structure.The takeup type structure be with the volume core be starting point, reel after by barrier film positive and negative electrode being isolated, the structure of this lithium battery electric core is the mid portion that positive and negative lug is arranged on electric core, positive and negative plate and lug thereof and barrier film are successively reeled to same direction, this structure battery is because lug is welded in inside, yielding surface irregularity even the generation groove of causing, the lug place easily produces short circuit phenomenon; And the lamination type electric cored structure is the positive/negative plate that size is close with battery case, separates with barrier film by the centre, repeat repeatedly superimposed and form a bean curd bulk, after respectively positive and negative lug is connected on the both positive and negative polarity leading-out terminal, put into metal-back, fluid injection forms.This battery battery core has multiple lug, because lug is to be made of metal forming as thin as a wafer, just occurs the fracture of part lug especially easily so couple together, thereby the problem that battery performance and capacity are normally brought into play occurs influence.No matter be the sort of battery battery core version, how lug is connected with leading-out terminal and electric current is derived is the key subjects that battery designing for manufacturing person research and develop always.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, low processing cost the battery leading-out terminal structure.
The utility model is achieved through the following technical solutions:
Design a kind of battery leading-out terminal structure, be provided with protective plate at electric core front end face, electric core both positive and negative polarity links by the lead-out terminal of deriving on sheet and the baffle, also is with face shield at the electric core front end that is provided with baffle and protective plate.
Protective plate is bonded in electric core front end face, and protective plate is that sheet is corresponding with electric core front end face shape.Deriving sheet is linked together electric core both positive and negative polarity and splicing ear by welding manner; splicing ear is arranged on the baffle face relative with electric core front end face, and splicing ear is connected by the lead-out terminal that is provided with on the protective circuit on the baffle and the baffle another side.
Face shield is the groove shape of an opening, bottom land be provided with baffle on the corresponding through hole of lead-out terminal shape, the battery battery core tail end is provided with the concavity drain pan that is nested with tail end.
The utility model compared with prior art has following remarkable result:
Battery conductive terminal structure provided by the utility model, when the protective plate that is shaped in advance that is arranged at electric core front end face has been avoided injection moulding in the shutoff venting under HTHP to the destruction of electric core, but also played insulation effect.The utility model processing technology is simplified relatively, low cost of manufacture.
Description of drawings
Fig. 1 is an exploded perspective view of the present utility model.
Fig. 2 is the schematic diagram that protective plate is positioned at electric core front end among Fig. 1;
Fig. 3 is the schematic appearance of packaged battery of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1-3, a kind of battery leading-out terminal structure includes battery battery core 7, is bonded with protective plate 6 on electric core front end face, after the mode that protective plate adopts moulding in advance processed according to the shape of electric core front end face, being bonded to electric core again had on the front end face of both positive and negative polarity.Protective plate is the plates of plastic colloid, is used for the venting of shutoff electricity core, makes the both positive and negative polarity of electric core exposed outside simultaneously.When being provided with protective plate and avoiding under HTHP operation, electric core end face, also plays the effect of insulation simultaneously to the destruction of electric core.
The utility model also is provided with baffle 3 at the battery battery core front end; this baffle is provided with the battery protecting circuit substrate; the setting of baffle is parallel with electric core front end face; the both positive and negative polarity 41,42 of battery battery core welds together by the splicing ear of deriving on sheet 51,52 and the baffle; splicing ear is arranged on the baffle face relative with electric core front end face; deriving sheet can be the nickel sheet, also can be other corresponding braces of deriving.Splicing ear is connected by the lead-out terminal 92 that is provided with on the protective circuit on the baffle and the baffle another side again.
The face shield 2 of this packaged battery is the groove shape cover body of an opening, and bottom land is provided with the corresponding through hole 21 of lead-out terminal 92 shapes on the baffle.Lead-out terminal 92 on the baffle another side can expose from the bottom through-hole 21 of face shield 2.
Described face shield is positioned electric core front end by injection molded.The electric core that promptly is connected with protective plate 6 and derivation plate 3 places in the injection molding machine die cavity; make the baffle location by the draw point in the die cavity; the i.e. position of controlling baffle and going up lead-out terminal by the draw point in the die cavity can accurately locate and exposed outside the through hole of face shield bottom lead-out terminal on the baffle thereby draw point blocks baffle by anchor point up and down.Inject the face shield that resin makes moulding at last and be fixed in electric core termination.
The utility model battery leading-out terminal structure also is equipped with concavity drain pan 8 at the battery battery core tail end, so that further protect battery battery core.The termination adds packing for later on packaged battery component again before and after the packaged battery battery core, and pastes insulative water-proof labeling 1 on calibrating terminal 91.
