Abstract
The utility model relates to an aluminium capacitor case with in an anti-explosion structure at the bottom end surface. The technical problem to be solved is that the aluminium case provided by the utility model has the characteristics of reasonable anti-explosion structure and good use effect. The technical scheme is that in a barrel-shaped aluminium capacitor case with a crux-shaped anti-explosion groove, the top end is open, and the anti-explosion groove is formed on the bottom end surface. The utility model is characterized in that the anti-explosion groove is crux-shaped, the depth of the groove is gradually reduced to the periphery of the crux from the center of the crux, the symmetric central line of the crux is coincided with the diameter of the bottom end surface of the aluminium case, the thickness of the wall part of the central position of the crux is more than 0.06mm, and the distance from the center of the crux to the center of the bottom end surface of the aluminium case is 0.5-8mm. The anti-explosion groove is formed on the outer surface of the bottom end of the aluminium case.
Description
Technical field
The utility model relates to a kind of tubular aluminum hull, specifically is the aluminium shell of capacitor that bottom end face is shaped on blast resistance construction.
Background technology
Capacitor is widely used conventional electrical components and parts; The liquid electrolytic capacitor of the common aluminum hull of employing wherein is because superior performance still is applied in a lot of fields.But this kind capacitor still has following deficiency, and promptly in use if moment is passed through big electric current, the conventional aluminium liquid electrolytic capacitor is easy to blast.For this reason, existing aluminum hull capacitor is shaped on explosion-proof groove in the bottom of tubular aluminum hull usually, makes it become region of stress concentration; When the capacitor internal pressure increases, at first allow explosion-proof groove cracking discharge electrolyte pressure, thereby significantly reduced the spraying range of electrolyte.Yet the explosion-proof groove of existing capacitor mostly is the straight trough of in-line; Breach when the defective of this kind structure is explosion-proof groove cracking is too little, and the speed that electrolyte pressure discharges is not enough, fails to satisfy customer requirements.
The utility model content
The purpose of this utility model provides a kind of improvement of tubular aluminium shell of capacitor, and this aluminum hull should have the characteristics that explosion-proof groove is rational in infrastructure, result of use is good.
The technical scheme that the utility model proposes is: a kind of tubular aluminium shell of capacitor that is shaped on the explosion-proof groove of crux, its top is uncovered, bottom end face is shaped on explosion-proof groove, it is characterized in that described explosion-proof groove is a crux, the degree of depth of this groove reduces around the mind-set from cross gradually, the symmetrical center line of cross overlaps with the diameter of aluminum hull bottom end face, and the wall portion thickness of this cross center is greater than 0.06mm.
The distance at described cross center and aluminum hull bottom end face center is 0.5-8mm.
Described explosion-proof groove is produced on the outer surface of aluminum hull bottom.
The beneficial effects of the utility model are: because the aluminum hull bottom end face is provided with the explosion-proof groove of crux, make this position become the weak link that stress is concentrated; When the capacitor internal pressure increases when making explosion-proof groove craze and transfiguration, the breach of formation is bigger, and the electrolyte that helps in the housing discharges rapidly, has result of use preferably, has satisfied user's needs.

Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is a right TV structure schematic diagram of the present utility model.
Embodiment
As shown in the figure: this tubular aluminium shell of capacitor 1, it is uncovered container-like in top; Aluminum hull bottom end face area is shaped on explosion-proof groove 2; This explosion-proof groove forms through punching press, and the outside is shown as the groove (barrel of groove must not be damaged) of crux.To strengthening gradually all around, the symmetrical center line 2-2 of cross overlaps with the diameter of aluminum hull bottom end face from cross center 2-1, and the wall portion thickness of this cross center is greater than 0.06mm.The width of explosion-proof groove and length then can be determined as required.As recommendation, the cross center 2-1 of explosion-proof groove, should with the axis of tubular aluminum hull be 0.5-8mm apart from the T distance of aluminum hull bottom end face center (promptly with).
Obviously, in this crux groove, position, crosspoint (being 2-1 position, cross center) is weakness anyhow.In case when the increase of capacitor internal pressure, explosion-proof groove craze and transfiguration, this position can at first be out of shape, splitting around four angles forms big breach, helps the rapid release of electrolyte.
