Present canopy-type aluminium electrolytic capacitor mainly contains two kinds: a kind of is conventional canopy-type aluminium electrolytic capacitor, it is by the core bag, cover plate is the aluminum hull composition of through hole with having only a side, the anodal lead-out tablet of core bag and negative pole lead-out tablet all are unidirectional drawing, the core bag is installed in the aluminum hull, the anodal lead-out tablet of core bag is riveted on the positive rivet of cover plate, and the negative pole lead-out tablet of core bag is riveted on the negative rivet of cover plate, and the side at the aluminum hull through hole encapsulates with cover plate then.This aluminium electrolytic capacitor can only uprightly be installed, and can not horizontally install.
Another kind of aluminium electrolytic capacitor, its anodal lead-out tablet is drawn in a side of aluminium electrolytic capacitor, and the negative pole lead-out tablet is drawn at the opposite side of aluminium electrolytic capacitor.This aluminium electrolytic capacitor can only horizontally be installed, and can not uprightly install.
The utility model content
The purpose of this utility model is to change the aluminum current electrolytic capacitor can only be uprightly or can only horizontally-mounted present situation, provide a kind of can be uprightly again can horizontally-mounted dual-purpose aluminium electrolytic capacitor, it can be met the different needs, effectively saved the space, also improved performance, made it can bear the impact of big electric current.
The purpose of this utility model is achieved through the following technical solutions: a kind of aluminium electrolytic capacitor of vertical/horizontal dual purpose, comprise cover plate, aluminium shell-and-core bag, its SMIS bag is positioned at aluminum hull, it is characterized in that: anodal lead-out tablet and negative pole lead-out tablet all extend to two ends in the described core bag, form axially two-way drawing, described aluminum hull is two through hole, the two ends of described aluminum hull encapsulate with cover plate respectively, the anodal lead-out tablet in the two ends of described core bag is riveted on the positive rivet of two cover plates, and the two ends negative pole lead-out tablet of core bag is riveted on the negative rivet of two cover plates.
In order better to realize the utility model, described cover plate and core parlor are equipped with compacting ring.The center of described compacting ring is one section needle-like projection, and the needle-like of compacting ring projection is inserted in the needle-like circular hole that core bag center forms naturally because of coiling, plays the fixed core bag.Compacting ring is provided with breach, is used for the slight end face that embeds the core bag when product encapsulates, and plays the strengthening core bag simultaneously and the circle that is fixed and clamped.Described compacting ring has two through holes, and two through holes of compacting ring pass anodal lead-out tablet and negative pole lead-out tablet respectively, works to isolate anodal lead-out tablet, negative pole lead-out tablet.Two through hole cross sections of described compacting ring are preferably semicircle, can save material effectively.
Described aluminum hull is a cylindrical shape, because the core bag of winding is cylindric, columnar aluminum hull more helps saving material and space; The two ends of aluminum hull are processed with groove, can be used for blocking cover plate, are more conducive to seal fixing.
Described cover plate has the weld tabs structure, helps the circuit firm welding and is connected with the convenient mode of connector that adopts.
The utility model has following advantage and effect with respect to prior art: (1) energy vertical/horizontal dual purpose; Can be uprightly again can horizontally-mounted dual-purpose aluminium electrolytic capacitor, can satisfy different instructions for uses, applicability is better, and can effectively save installing space; (2) improved performance, made it can bear the impact of big electric current; Because its anodal lead-out tablet and negative pole lead-out tablet pass from the center of capacitor simultaneously, extend to two ends respectively, form axially two-way drawing, so capacitor can bear bigger rush of current.
