Share on whole market alreadys exceed 50%.Lithium battery top cap weight at present on new-energy automobile is bigger, and price is high,
It is oxidized easily.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of large capacity with fool-proof mechanism
The connection structure of lithium battery top cap.
The utility model is achieved through the following technical solutions:
A kind of connection structure of the high-capacity lithium battery top cover with fool-proof mechanism includes positive screening glass, cathode guarantor
Bluff piece, positive strap, negative straps, positive rivet, cathode rivet, stop frame, top cover substrate, the weak guide card of anode, cathode
Insulation spacer and two pieces of aluminium pressing plates, the positive rivet sequentially pass through positive screening glass, positive strap, stop frame, top cover
The rivet hole of substrate, anode be weak to lead gasket and mutually rivets fixation with one of aluminium pressing plate, and the cathode rivet sequentially passes through negative
Pole screening glass, negative straps, stop frame, the rivet hole of top cover substrate, negative insulation gasket and another piece of aluminium pressing plate mutually rivet
It is fixed, it is provided with explosion-proof cage apertures, explosion-proof fenestra and liquid injection hole on the top cover substrate, is equipped in explosion-proof cage apertures explosion-proof
Cover, is equipped with rupture pressure disc on explosion-proof fenestra, chemical conversion nail and liquid injection port mounting is equipped in liquid injection hole, in the positive riveting
Nail, cathode rivet, stop frame, positive weak lead are respectively equipped with fool-proof mechanism on gasket and negative insulation gasket.Rivet, stop frame riveting
Nail hole, base plate rivets hole, the outer dimension of insulation spacer positive and negative anodes are all the same, be easy to cause employee anti-loaded.It will by design end
The profile arrangement of component is different, and positive/negative accessory is made to have nuance, and under compact cooperation, fool-proof mechanism, which plays, to be made
With, be assemblied in each component can only on fixed position, reduce scrappage.
Sealing ring is respectively equipped between the stop frame and positive rivet and cathode rivet.
