Abstract
The utility model discloses an upper gasket which can enable a novel pole rod of a high capacity lithium power battery to be insulated and positioned. The high capacity lithium power battery integrated upper gasket is realized through the following technical proposal: the upper gasket comprises an insulator; the upper gasket is provided with a positive pole rod insulation protection through-hole and a negative pole rod insulation protection through-hole; a positioning concave groove is arranged in the upper gasket and is concentric with the insulation protection through-holes; and the positioning concave groove is matched with the shape of a pole rod positioning table. The upper gasket can ensure the insulation safety for the discharge of heavy current of the high capacity power battery, and meet the requirement of high capacity power battery discharge insulation with current above 110A. At the same time, the structure has the positioning function, can greatly improve the assembly efficiency of the pole rod, simplify the assembly process and procedure, and reduce the production cost and the product cost.
Description
Technical field
The utility model relates to the lithium ion battery field, in particular, relates to a kind of Upper gasket that can make the insulation of high-capacity lithium-ion power battery pole, location and sealing.
Background technology
The range of application of lithium ion battery more and more widely, particularly capacity is fast-developing especially in the development of the above battery of 50Ah in recent years.The built-in electrical insulation of battery electrode column comprises between the positive and negative terminals positive terminal and negative plate, negative terminal and positive plate, the insulation between pole and cap, the housing simultaneously.Also has the also further investigation day by day of requirements such as positioned internal of pole.
Thin and thick differs for electrokinetic cell cap thickness at present, and different manufacturers thickness is not quite similar, and the insulation of pole and location normally are made on the cap mostly and are injected into cap, is separated and is formed hermetically-sealed construction by the working of plastics insulation.And just need the insulation system of other kind forms for the thin case design of cap.The insulation safety of battery be great-capacity power battery make and design process in key technology emphasis and requirement.The slim Upper gasket of function singleness simple in structure is generally adopted in the most at present big vehicle-mounted dynamic lithium battery of capacity inside; more effective positive and negative terminals is not played positioning action; only insulation there is certain effect to a certain extent; heavy-current discharge is not more then had more effective protection, thereby very big potential safety hazard is arranged.If utmost point group and pole connect and can cause internal short-circuit of battery in the lithium battery use, produce serious safety problem, even blast.
The utility model content
The purpose of this utility model is solution and overcomes shortcoming of the prior art and deficiency, promptly locatees and insulate and can not play a role simultaneously, and a kind of Upper gasket that can make novel pole insulation of high-capacity lithium-ion power battery and location is provided.
The utility model high-capacity lithium-ion power battery is pad on the whole; be achieved by following technical proposals; Upper gasket is made of insulator; Upper gasket is provided with positive and negative pole insulation protection through hole respectively; with the concentric detent that is provided with of insulation protection through hole, described detent and pole positioning table shape are complementary in the Upper gasket.
The utility model structure has following beneficial effect:
The utility model Upper gasket table body is provided with detent, during assembling at first the pole location of from groove, packing into, then with the pole nut screwing clamping of battery.The Upper gasket structure that this pole location cooperates can guarantee the fail safe of battery, effectively prevents the possibility of battery short circuit.
The utility model is requisite key structure of high capacity cell and parts.The utility model has played the sound assurance effect for the insulation safety of power high capacity cell heavy-current discharge, can satisfy the above great-capacity power battery discharge insulating requirements of 100A electric current, this structure has also designed the pole positioning function simultaneously, can improve the pole efficiency of assembling greatly, simplify assembly technology, operation, reduce the cost of production and product, improve product assembly quality, improve the competitiveness of product in market greatly.And in the lithium-ion-power cell manufacture process, this Upper gasket can play very big protective effect, can guarantee that positive and negative terminals can not come off, and isolates with utmost point group, has played necessary insulation protection and positioning action.

Fig. 3 is the utility model vertical view;
Fig. 4 is large-capacity power lithium battery positive and negative terminals and the utility model installation diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model is provided with positive terminal insulation protection hole 1, negative terminal insulation protection hole 2; the utility model lower surface is a utmost point group insulating surfaces 3; the utility model upper surface is a cap insulating surfaces 4, as shown in Figure 2, in the Upper gasket with the concentric pole detent 5 that is provided with of insulation protection through hole.Fig. 3 is a vertical view of the present utility model.
As shown in Figure 4, pole and 1,2 assemblings of insulation protection hole, the pole positioning table cooperates with the Upper gasket location notch and cooperation, situation in battery.
The function of this Upper gasket new construction is the positive and negative terminals of lithium battery insulation stationary positioned, guarantees in use can not produce phenomenons such as the short circuit that comes off.As shown in Figure 4 by the insulation protection pore structure, can guarantee pole not can with the housing short circuit, simultaneously can with the Upper gasket increase air-tightness that closely cooperates.And with cooperate at detent prevent that pole from using and assembly project in the moment of torsion rotation, prevent to come off and short circuit.
