Description
Technical field
The present invention relates to field of batteries, be specifically related to battery cover board assembly.
Background technology
Lithium ion battery is widely used on notebook computer, video camera, digital camera, PDA (personal digital assistant) and other communication terminal product.Its specification is many, application is wide, demand is big.With the column lithium ion battery is example, occurred the battery of liquid injection hole in cover plate assembly central authorities, but connected mode is complicated between the each several part of its cover plate assembly, causes complex structure, and cover plate is too thick, poor sealing performance.
Chinese patent application CN2833898 discloses lithium ion battery cover board assembly and battery, and the cover plate assembly in this patent is to be made of riveted joint pole plate on the cover board, and wherein pole plate central authorities are provided with liquid injection hole.Because pole plate is that therefore riveted joint is connected with cover plate, the pole plate after the cooperation is subjected to powerful extruding back that deformation takes place, and liquid injection hole default on it causes the liquid injection hole distortion, diminishes also along with the deformation of pole plate changes, and is unfavorable for the shutoff of follow-up liquid injection hole.Therefore need to improve.
Summary of the invention
Technical problem to be solved of the present invention is to differ in the liquid injection hole aperture of existing battery cover board assembly on it, the technical problem of difficult shutoff, thus provide a kind of liquid injection hole aperture high conformity to be easy to the battery cover board assembly of shutoff.
Technical scheme of the present invention, a kind of battery cover board assembly, comprise cover plate, insulating part and tubular rivet, this tubular rivet comprises head and has the connecting portion of through hole, described insulating part and cover plate rivet together by described tubular rivet, and at the terminal kink that forms of the connecting portion of described tubular rivet, it is characterized in that: the head of described tubular rivet is provided with a conductive plate, also be provided with a liquid injection hole on this conductive plate, the through hole of this liquid injection hole and described connecting portion connects.
Further, described conductive plate is provided with thin wall cylinder to the connecting portion through hole bearing of trend of described tubular rivet, and this thin wall cylinder and liquid injection hole connect.
Further, described thin wall cylinder external diameter less than with the connecting portion internal diameter.
Further, the big up and small down gathering shape of described liquid injection hole opening.
Further, be provided with annular gasket between described kink and the seal.
Further, be provided with the electrode leads to client that is used to be connected battery electrode between described kink and the seal.
Further, be provided with annular gasket between described kink and the seal, be used to be connected the electrode leads to client of battery electrode, lamination order is kink, annular gasket, electrode leads to client.
Useful technique effect of the present invention: 1) thin wall cylinder and the connecting portion inside of cover plate assembly formation liquid injection hole provided by the invention are separated from each other; When being subjected to powerful riveted joint, connecting portion generation deformation can not influence the deformation of battery thin wall cylinder, thereby can guarantee the thin wall cylinder endoporus, i.e. not deformation of liquid injection hole.2) the big up and small down gathering shape of liquid injection hole opening, fluid injection syringe needle when helping fluid injection, and the location of shutoff liquid injection hole shutoff plug.3) annular gasket can make the little deformation of seal can rivet fastness.4) the lug extension stem makes things convenient for the electrode welding.
