Brief description of the drawings
Fig. 1 is the cross-sectional view of patent of the present invention.
Fig. 2 is the Longitudinal cross section schematic of patent of the present invention.
Embodiment
As shown in Figure 1, Figure 2, a kind of lithium battery cap board component, comprising cover plate 1, bar hole is opened up on cover plate 1, is worn in the bar hole
If solid pole 4, the bottom of four sides of pole 4 all sets ladder 21, and stair-stepping sealing gasket 2, pole are cased with ladder 21
Position of four sides of post 4 on sealing gasket 2 opens up groove 22, plastic parts 3 is fixed in the depression 22, plastic parts 3 is outside
Extension is alignd with sealing gasket 2, makes the space between plastic parts 3, sealing gasket 2 be an endless groove, the bar shaped of endless groove card cover plate 1
The hole wall in hole, to complete the fixation of cover plate 1, pole 4.
Sealing gasket 2 can reduce cover plate 1 and the vibrations of the horizontal direction of pole 4 or vertical direction.
Sealing gasket 2, plastic parts 3 are designed as two parts, it is convenient for assembly.
The material of cover plate 1 is aluminium, bar hole punch forming.Micro-arc anodic oxidation after cover plate 1 is molded（micro-arc
oxidation）Thick into 10-15 microns, fine and close, wear-resisting, heat conduction, the Al of insulation2O3Ceramic layer.
The material of pole is aluminium or copper, its plating nickel on surface, and groove uses punch forming.
The material of sealing gasket 2 is fluorubber（fluororubber）.
The material of plastic parts 3 is PFA（Meltability polytetrafluorethyletubular）, or be PPS（Polyphenylene sulfide）With carbon fiber
Mixture；Using the technique of heat injection, pole is set to be fixedly connected with cover plate.Because the inward flange of plastic parts 3 is all set in groove
22 inside, it is cumbersome when manufacture, it is the technique that this can use heat injection.
With reference to shown in Fig. 1,2, now manufacture method of the present invention is described below：
