Abstract
The utility model discloses a cover board for lithium ion electrokinetic cell, comprising a board and a plastic pad applied on the board. The board where applied pad is opened an ellipses electrode hole, inside which arranged an electrode threading the plastic pad. An 'L' shape electrode connection strap is arranged in the plastic pad. An electrode pole threads the electrode connection strap, airproofing and tightly fixed the electrode connection strap and the plastic pad on the board, thereby making the plastic pad, the board and the electrode pole injection-molded to an integral. The cover board for lithium ion electrokinetic cell of the utility model injection-molds the board and the electrode pole to an integral, making the battery employing said cover board have good hermeticity in the place of the electrode pole, which can further avoid the defect of generating gap for the electrode pole rotating relative to the plastic pad during sub-linking with outer circuit terminal.
Description
Technical field
The utility model relates to a kind of lithium-ion-power cell cover plate.
Background technology
The cover plate of lithium-ion-power cell commonly used comprises plate body and plastic spacer at present, and plate body is provided with can work as the pole that bolt uses, and pole also plays the effect of fastening plastic spacer in conduction.In the process of fastening plastic spacer, can make the pole twisting, drive inner battery pole ear distortion simultaneously, the lug intensity decreases, location dislocation causes battery to open circuit and short circuit easily, thereby brings serious potential safety hazard; And in the process of fastening electrode, form the gap between pole and the plastic spacer easily, influence the sealing of cover plate.
Summary of the invention
Technical problem to be solved in the utility model is at above deficiency, and a kind of lithium-ion-power cell cover plate that can overcome above-mentioned shortcoming is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lithium-ion-power cell cover plate, comprise plate body and the plastic spacer that is fitted on the plate body, on the plate body at plastic spacer place, have electrode hole, be provided with the electrode that passes plastic spacer in the electrode hole, be provided with electrode connecting piece on plastic spacer, pole passes electrode connecting piece electrode connecting piece and plastic spacer sealing is fastened on the plate body.
Above-mentioned electrode connecting piece is " L " shape.
Above-mentioned electrode hole is oval.
Above-mentioned plastic spacer is fitted on the plate body upper surface and lower surface at electrode hole place.
The middle part of above-mentioned pole is provided with square block, and square block is positioned at the below of plate body, has on the plastic spacer of plate body lower surface and the equiform groove of square block, and square block is inserted in the groove.
The transverse plate of above-mentioned electrode connecting piece is identical with the shape of plastic spacer.
Above-mentioned plastic spacer, plate body and pole are injected into one.
The beneficial effects of the utility model are: because plate body, plastic spacer and pole adopt injection molding way to connect as one, when both having prevented fastening pole owing to rotating the potential safety hazard that produces, solved the problem that there are the gap in pole and plastic spacer again: line scan pickup coil side outside the effect of " L " shape electrode connecting piece has been avoided directly being connected on pole, but tightening nut perpendicular to the pole direction, this has just reduced the moment of torsion of pole, avoid the gap occurring between pole and plastic spacer, thereby can not have influence on the sealing of pole; Owing to adopted technique scheme, the utility model has effectively prevented the rotation of pole when realizing the conventional cover plate function, and has strengthened the sealing at pole position, thereby has improved the security performance of battery greatly.
