Abstract
The utility model provides a lithium battery cover plate, which comprises a cover plate substrate provided with a liquid filling hole and a through hole, wherein a plastic insulator pipe is formed in the through hole via an injection molding form, the plastic insulator pipe is fastened onto the through hole, a rivet is inserted and fixed in the plastic insulator pipe, a pin penetrates through the lower portion of the rivet and extends out from one side, and the extending pin is fixed with the plastic insulator pipe via a spot welding manner. The lithium battery cover plate has simple structure, fewer parts and low manufacturing cost and adopts the spot welding manner, thereby reducing internal resistance inside batteries and incidence of flashing and missing solder.
Description
Technical field
The utility model relates to a kind of parts of lithium battery, relates in particular to a kind of lithium battery cover plate.
Background technology
In lithium battery electric core,, because prior art all adopts rivet usually, very easily cause loose contact and cause resistance to rise, and be difficult to control because parts such as cover plate have resistance.On the other hand, when the cover plate extraction electrode, prior art constructions is more complicated all generally, must cause sealing property and reliability of insulating properties to reduce, and the Shooting Technique complexity, cause production efficiency to reduce.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of simple in structure, good airproof performance, can reduce the inner internal resistance of parts, and can keep the battery cover board of its internal resistance stability.
The utility model is achieved through the following technical solutions: a kind of lithium battery Aluminum cover, comprise the cover plate substrate, offer liquid injection hole and through hole on the cover plate substrate, through hole is interior by injection molding way shaping plastic cement insulator pipe, plastic cement insulator pipe clamp is buckled on the through hole, the interspersed rivet that is fixed with in the plastic cement insulator pipe, pin is interspersed in the rivet bottom and stretches out from a side, and pin that stretches out and plastic cement insulator pipe are fixed by the means of spot welds mode.
By technique scheme, simplify the structure of battery cover board inside, thereby reduced the battery cover board internal resistance, and had only a pad, simplified production technology, reduced the inside battery scintillation, lose weldering phenomenon incidence.
Description of drawings
Fig. 1 is the utility model structural cover board substrate schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model plastic cement insulator pipe cutaway view;
Embodiment
Below in conjunction with accompanying drawing the utility model content is done and to be described in further detail:
Shown in Fig. 1-2, the cover plate substrate 1 that comprises strip, on cover plate substrate 1, offer liquid injection hole and through hole 2, the inwall of through hole 2 is the inclined plane, through hole 2 inwalls are formed with plastic cement insulator pipe 3 with through hole 2 buckles by injection molding way, and the plastic cement insulator pipe 3 that is injection-moulded on the through hole 2 is buckled in through hole 2 both sides.Intert by friction tight mode in the insulator pipe 3 and be fixed with rivet 4, pin 5 is interspersed in rivet 4, and stretches out from a side, and the pin 5 that stretches out and plastic cement insulator pipe 3 are fixed by the means of spot welds mode, form solder joint 6.
The above is a better embodiment of the present utility model only, is not the qualification to the utility model protection range, and equivalent transformation that those skilled in the art is done on this basis and distortion all belong to protection category of the present utility model.
