By technique scheme, triode is fastened in triode groove by the triode fixture block on capping bottom surface, and pincard is combined in pin draw-in groove by three pin fixture blocks, and fin is fastened in fin groove by fin fixture block.Above-mentioned engaging is tight engaging, with the steadiness ensureing triode, three pins, fin are located.
By technique scheme, to dismantle described encapsulation triode, only capping need be taken away from base, can take out triode, three pins, fin, so, the dismounting of described encapsulation triode is more convenient.
As further improvement of the utility model, described cover rim offers draw-in groove, and described buckle coordinates with draw-in groove.Design like this, when capping is fastened on base, buckle coordinates with draw-in groove, is fastened on stability on base to improve capping.
As further improvement of the utility model, in described pin groove, establish protuberance.Described pin is established the groove matched with pin groove inner bulge, so design, even if there is external force pull pin, pin also can not from base by pull out.
As further improvement of the utility model, in described fin groove, establish recess.Accordingly, fin is provided with protuberance, so, to ensure that fin is positioned in fin groove exactly.
As further improvement of the utility model, described fin is positioned at bottom triode, and fin contacts with bottom triode, and the fin of outstanding base edge can dispel the heat better.
