Abstract
The utility model of an aluminum electrolytic capacitor is elaborated by extrusion of the aluminum stick with cold pressing model by application of a measuring truck with pure aluminum terminal of a spiral type phenol formaldehyde cover. The utility model comprises a first diameter part, a second diameter part and a third diameter part. A groove and the first flange and the second flange are provided for second diameter part. The knurling is arranged on the bottom of the groove, which not only increases screw torque but also enlarges the contacting surface between the pure aluminum terminal and the phenol formaldehyde plastic. In addition, the combining power between the pure aluminum terminal and the phenol formaldehyde plastic is improved. with good sealing effects, the utility model can realize the leakage-free goal.
Description
[technical field]
The utility model relates to the aluminium electrolytic capacitor field, and particularly a kind of aluminium electrolytic capacitor is with the fine aluminium terminal of spiral phenolic aldehyde cover plate.
[background technology]
The aluminum current electrolytic capacitor uses the fine aluminium rod through lathe grinding machine-shaping with the fine aluminium terminal of spiral phenolic aldehyde cover plate more, do not change the crystal phase structure of fine aluminium, the fine aluminium terminal softness that processes is yielding, the screw thread torque is little, make the aluminium electrolytic capacitor rear thread and often skid, cause the inefficacy of capacitor; In addition, the fine aluminium terminal surfaces profile of lathe grinding machine-shaping is simply cylindrical, because it is simple in structure, do not adopt particular design, cause seepage electrolyte between phenolic plastics and the fine aluminium terminal easily, directly influence the serviceability and the life-span of aluminium electrolytic capacitor, caused the inefficacy of aluminium electrolytic capacitor.
[novel content]
For addressing the above problem, the purpose of this utility model is to provide that a kind of screw thread torque is big, good sealing effect, electrolyte not the aluminium electrolytic capacitor of easy to leak with the fine aluminium terminal of spiral phenolic aldehyde cover plate.
For achieving the above object, this creation aluminium electrolytic capacitor processes with measuring truck by with cold stamping die aluminium bar being pushed the back with the fine aluminium terminal of spiral phenolic aldehyde cover plate, comprise first diameter portion, second diameter portion and the 3rd diameter portion that are cylindricality, second diameter portion is provided with groove and first, second flange, and the bottom portion of groove surface is provided with annular knurl.
Further, described first, second diameter engages and is in first flange, one side and is provided with arcwall face;
Further, described second flange is provided with level and prolongs the reclinate ring-shaped edge portion that rises;
Further, described second flange roughly is an inverted disc-shape;
Further, described groove is arranged at the second flange both sides.
Compared to prior art, this creation is by being provided with groove and flange in second diameter portion, the bottom portion of groove surface is provided with annular knurl, thereby make the screw thread moment of torsion strengthen, increase the contact surface of fine aluminium terminal and phenolic plastics, improve the adhesion of phenolic plastics and fine aluminium terminal surfaces, good sealing effect reaches the purpose that prevents seepage

Fig. 2 be Fig. 1 along A-A to cutaway view;
Fig. 3 creates the stereogram of another embodiment for this;
Fig. 4 be Fig. 3 along A '-A ' to cutaway view.
[embodiment]
Please refer to Figure 1 and Figure 2, a kind of aluminium electrolytic capacitor of the utility model is with the fine aluminium terminal of spiral phenolic aldehyde cover plate, by aluminium bar extruding back being processed with measuring truck, comprise cylindrical first diameter portion 1, second diameter portion 2 and the 3rd diameter portion 3 with cold stamping die.
Fig. 3, Figure 4 shows that another embodiment of this creation, it includes the first, second, third and the 4th diameter portion 1 ', 2 ', 3 ', 4 '; Wherein second diameter portion 2 ' is provided with first, second flange 10 ', 20 ' and groove 11 ', bottom portion of groove surface and second flange, 20 ' surface are provided with annular knurl 110 ', so that the fine aluminium terminal surfaces is coarse, improve the adhesion of phenolic plastics and fine aluminium terminal surfaces, reach the purpose that prevents seepage.
Owing to adopted such scheme,, improved sealing property by increasing fine aluminium termination contact rough interface degree and increasing flange; The aluminium electrolytic capacitor high temperature service life increases substantially, through the product endurance test, the result shows the aluminium electrolytic capacitor more than the 400wv that makes with this creation, adds electric test under the condition of 105 ℃ of 8000h, and the cover plate aluminium terminal does not have solution leakage, anodic attack sign; Fine aluminium terminal screw thread torque is brought up to 8N.M by traditional 3N.M; Single fine aluminium terminal aluminium consumption reduces by 40%, and production efficiency improves 200%.
Most preferred embodiment described above only is that this creation is set forth and illustrated, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
