Description
Technical Field
The utility model relates to an aluminum ring centre gripping formula fixed knot constructs combination cap.
Background
The existing lithium ion battery generally adopts a cap without a top cover, and the explosion-proof aluminum sheet and the connecting aluminum sheet are connected through the isolating ring, so that the explosion-proof aluminum sheet is contacted with the middle of the connecting aluminum sheet, the two ends of the explosion-proof aluminum sheet are separated, a pressure relief cavity is formed, and once the internal short circuit pressure of the battery is increased, a crack on the explosion-proof aluminum sheet can be broken to release the internal pressure of the battery. In the practical application process, the phenomenon that welding spots between the explosion-proof aluminum sheet and the connecting aluminum sheet fall off is easy to occur, so that the connecting aluminum sheet is in a short circuit state with the explosion-proof aluminum sheet again due to shaking in the battery transportation process; meanwhile, the explosion-proof aluminum sheet is insufficient in supporting force, so that the strength is poor when an external accessory is welded on the surface of the explosion-proof aluminum sheet.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides an aluminum ring clamping type fixed structure combined cap which can improve the firm installation strength.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an aluminum ring centre gripping formula fixed knot constructs combination cap, has the sealing washer, installs explosion-proof aluminum sheet between the sealing washer inner circle, and explosion-proof aluminum sheet below is equipped with the connection aluminum sheet, has the boss with explosion-proof aluminum sheet bottom surface laminating in the middle of the connection aluminum sheet, and the boss periphery has the pressure release chamber, sets up the air vent in intercommunication pressure release chamber on the connection aluminum sheet, is equipped with the spacing ring in the pressure release chamber, explosion-proof aluminum sheet outer fringe have down and inwards buckle the infolding draw-in groove that forms, the spacing ring bottom has the ring channel, connect aluminum sheet periphery card income in the ring channel, in roll over the draw-in groove and be equipped with the aluminum ring, the aluminum ring have the card go into the horizontal edge in the infolding draw-in groove and to the hypotenuse.
Further, for improving the explosion-proof effect, the explosion-proof aluminum sheet at the pressure relief cavity is provided with an upward bulge, and the inner wall of the bulge is provided with a split groove with a downward opening.
The utility model has the advantages that: the utility model discloses to connect the aluminum sheet chucking in the ring channel of cage, clamp the aluminum ring in the infolding draw-in groove of explosion-proof aluminum sheet, press from both sides tight cage through the aluminum ring laminating to having improved and having connected aluminum sheet installation firmness, having prevented that the solder joint from causing rocking of connecting the aluminum sheet when droing, having improved the security of lithium cell block, also correspondingly improved the installation strength of explosion-proof aluminum sheet simultaneously.
