Abstract
The utility model relates to an aluminum electrolytic capacitor with a lengthening guide needle at a stalk part, which comprises aluminum foil, electrolytic paper and electrolytic liquid in the aluminum electrolytic capacitor, an aluminum-made outer shell coated outside the aluminum electrolytic capacitor, a rubber plug and an insulating film layer thereof. The stalk part of the lengthening guide needle passes through the rubber plug, and is sheathed with the aluminum-made outer shell. Rolling slots are arranged at the contact positions of the aluminum-made outer shell, the rubber plug and the stalk part of the lengthening guide needle. The utility model is characterized in that the stalk part of the lengthening guide needle is correspondingly increased to 0.5 to 1.5 mm on the basis of original length of 1.0 to 5.0 mm, and the width of the rolling slots is also correspondingly increased to 0.3 to 1.2 mm. Welding points at the stalk part of the lengthening guide needle expose at the radial end of the aluminum electrolytic capacitor. The length of the stalk part of the lengthening guide needle is increased, so the sealing area is large after contact the rubber plug, the sealing strength is increased, the width of the rolling slots are correspondingly increased, and the sealing holding force is increased. In addition, the stalk part of the lengthening guide needle is lengthened, which enables active molecules in the aluminum electrolytic capacitor to increase to external diffusion paths.
Description
[technical field]
The utility model relates to guide pin formula aluminium electrolytic capacitor, relates in particular to a kind of aluminium electrolytic capacitor with stalk portion lengthening guide pin.
[background technology]
Generally speaking, the sealing of guide pin formula aluminium electrolytic capacitor, be to finish by aluminum hull inwall and the tight extruding of rubber stopper and guide pin stalk portion, guide pin is to play a key member of drawing positive and negative electrode and circuit interconnect function from aluminium electrolytic capacitor inside, the fine aluminium afterbody edge nail of guide pin is in the core bag part of the aluminium electrolytic capacitor that is made of positive and negative aluminium foil, electrolytic paper and electrolyte combination, sealing rubber stopper part in neat formation is passed by guide pin stalk portion, and last front end reaches the aluminium electrolytic capacitor outside.In the general course of processing, can push outer wall by the circumference convex type mould on the surface of aluminium shell, make the circumferential interior distortion that produces of aluminium shell, becoming has the together obviously planform of groove, and Here it is so-called slot rolling is because the needs of sealing, slot rolling must have certain width, not so do not reach seal standard, and medium-sized guide pin just makes the solder joint of guide pin stalk portion be hidden in rubber stopper inside after the width that has guaranteed slot rolling, be difficult for seeing.Present guide pin exists rubber stopper resilient grip area little because the short problem of stalk portion causes the slot rolling positional fault, stability is not enough, the aluminium electrolytic capacitor electrolyte inside is to the short problem of outside the evolving path, and the sealing function that can not play causes the aluminium electrolytic capacitor life-span to be given a discount.
[summary of the invention]
The utility model provides a kind of aluminium electrolytic capacitor with elongated guide pin stalk portion that prolongs guide pin stalk minister degree, can increase rubber stopper resilient grip area, the outside the evolving path of prolongation aluminium electrolytic capacitor electrolyte inside, raising aluminium electrolytic capacitor overall operation stability for addressing the above problem.
The technical scheme that the utility model addresses the above problem is: the utility model relates to a kind of aluminium electrolytic capacitor with stalk portion lengthening guide pin, its composition comprises aluminium foil, electrolytic paper and the electrolyte of aluminium electrolytic capacitor inside, and the outside of aluminium electrolytic capacitor coats aluminium shell and rubber stopper and insulating film layer thereof.Guide pin stalk portion pass rubber stopper and with the aluminium shell suit, contact position in aluminium shell and rubber stopper and guide pin stalk portion is provided with slot rolling, it is characterized in that, the stalk minister degree of guide pin has increased 0.5-1.5mm on the basis of original 1.0-5.0mm, the also corresponding increase of the width of slot rolling 0.3-1.2mm, guide pin stalk portion solder joint exposes the longitudinal end at aluminium electrolytic capacitor.
The beneficial effects of the utility model are: the guide pin stalk minister degree of aluminium electrolytic capacitor increases, and bigger with the sealing area of rubber stopper, sealing intensity increases, sealing improves, can more effectively prevent electrolyte leakage, the width of slot rolling increases, and has increased sealing and has held dynamics; Guide pin stalk portion solder joint as seen, this feature can fine differentiation and common aluminium electrolytic capacitor.Prolonged the stalk portion of guide pin in addition, made the aluminium electrolytic capacitor electrolyte inside increase to outside the evolving path.Guide pin stalk portion solder joint height seals below the height of limit at alminium electrolytic condenser, outside naked eyes as seen, this feature can be distinguished by fine and common aluminium electrolytic capacitor.

Fig. 1 is a plain edition aluminium electrolytic capacitor cutaway view;
Fig. 2 is the aluminium electrolytic capacitor cutaway view with elongated guide pin.
Among the figure: 1, shell; 2, guide pin; 3, guide pin stalk portion; 4, rubber stopper; 5, slot rolling.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
The aluminium electrolytic capacitor that the utility model is related with stalk portion extended type guide pin, structure comprises the aluminium foil of aluminium electrolytic capacitor inside, electrolytic paper and electrolyte, the outside of aluminium electrolytic capacitor coats aluminium shell 1, the tail end of guide pin 2 is buried by positive and negative aluminium foil, the aluminium electrolytic capacitor inside that electrolytic paper and electrolyte combination constitute, guide pin stalk portion 3 has encapsulated rubber stopper 4 in neat formation, it is characterized in that, guide pin stalk portion 3 length have increased 0.5-1.5mm on the basis of original 1.0-5.0mm, the also corresponding increase of the width of slot rolling 5 0.3-1.2mm, guide pin stalk portion 3 solder joints expose the longitudinal end at aluminium electrolytic capacitor.
Referring to accompanying drawing, by contrasting medium-sized aluminium electrolytic capacitor and aluminium electrolytic capacitor, after guide pin stalk portion 3 has extended as can be seen, use the protruding capable mould of circumference of bigger model to push along shell with elongated guide pin, allow shell 1 and rubber stopper 4 all be out of shape and be pressed on guide pin stalk portion 3, compacting sealing.
Usefulness of the present utility model is to obstruct minister's degree to be increased, bigger with the sealing area of rubber stopper, and sealing intensity increases, and sealing improves, and can more effectively prevent electrolyte leakage, and the width of slot rolling increases, and has increased sealing and has held dynamics; Guide pin stalk portion solder joint as seen, this feature can fine differentiation and common aluminium electrolytic capacitor.Prolonged the stalk portion of guide pin in addition, made the aluminium electrolytic capacitor electrolyte inside increase to outside the evolving path.
