Abstract
An aluminum electrolytic capacitor provided with an installing and fixing structure at the bottom comprises a kernel (1), a shell (2), a lead-out electrode (3), a sealing gasket (6) and a cover plate (4), wherein the kernel (1) is formed by wrapping a roll core (11) by an electrolytic aluminum foil, electrolytic paper and electrolyte. The aluminum electrolytic capacitor is characterized in that the a bolt (7) is arranged in the middle of the bottom of the shell (2), one end of the bolt is adaptive to an inner hole of the roll core (11) and inserted into the inner hole of the roll core (11) to be fixed, and the other end thereof is provided with thread and extends out of the bottom of the shell (2). The aluminum electrolytic capacitor does not need to use a special metal spider or plastic spider, and is provided with the installing and fixing structure at the bottom. The aluminum electrolytic capacitor has simple structure and small occupied area; as metal has good thermal conductivity and strong radiating capability, the metal bolt can be directly arranged on a metal radiating plate of equipment, and the metal radiating plate is more beneficial to prolonging the service life of the aluminum electrolytic capacitor and increasing the utility value of the equipment if under the action of a radiating fan.
Description
[technical field]
The utility model relates to a kind of electrolytic capacitor, refers to that especially the aluminium electrolytic capacitor of mount fixing structure is arranged at a kind of bottom.
[background technology]
Aluminium electrolytic capacitor is made up of parts such as kernel, shell, leadout electrode, sealing gasket and cover plates.Kernel wraps up the volume core by electrolysis aluminium foil, electrolytic paper and electrolyte to be formed, and the large-scale aluminum electrolysis capacitor volume is big, and weight is big, uses when installing and must use metal spider or plastic cement spider indirect securement.Install because mostly spider is outer encirclement formula, erection space is bigger, and the installation of cannot standing upside down, and is incompatible under some machine mounting condition.
[summary of the invention]
At the shortcoming of prior art, the purpose of this utility model is to provide a kind of aluminium electrolytic capacitor that need not use special metal spider or plastic cement spider, bottom that mount fixing structure is arranged.
The technical scheme that its technical problem that solves the utility model adopts is: comprise kernel, shell, leadout electrode, sealing gasket and cover plate, kernel is made up of electrolysis aluminium foil, electrolytic paper and electrolyte parcel volume core, it is characterized in that; There is a bolt centre of outer casing bottom, an end of this bolt with volume in-core hole suitable and insert fixing in the volume core hole, the other end is threaded and stretch out outer casing bottom.
Below cover plate, the cover plate reinforcement can be set, and with the opening of shell to the parallel tension cover plate of inner edge flange, kernel is subjected to from the last downforce of shell and cover plate and fastening loosening, simultaneously the reinforcement of aluminum hull bottom, cover inner surface can prevent the kernel axial rotation like this at the stressing conditions into core surface that sink.
The beneficial effects of the utility model are: need not use special metal spider or plastic cement spider, simple in structure, area occupied is little, metal bolts can be directly installed on the heat-dissipating metal sheet of equipment in addition, thermal conductivity, heat-sinking capability that metal is good are strong, if under the effect of radiator fan, more help the prolongation in the useful life of aluminium electrolytic capacitor, increase the value of equipment.
