Abstract
The utility model discloses an aluminum electrolytic capacitor with a firm structure, which is of a cylindrical structure and comprises an electric core body, a packaging metal shell and a packaging terminal cover plate, wherein the inner surface of the cover plate is provided with a cover plate reinforcing rib, and the inner surface of the bottom part of the metal shell is provided with a shell reinforcing rib; the outer wall of the metal shell is provided with a plurality of inner concaves, the inner concaves form bumps on the inner wall of the metal shell so as to extrude the metal shell to coat the electric core body, thereby enabling the electric core body to be fastened under the extrusion of the plurality of the bumps. Fastening and fixation of upper and lower parts are achieved through pressing the cover plate reinforcing rib on the inner surface of the metal cover plate into an insulating material of an electric core, and pressing the shell reinforcing rib on the bottom part of the metal shell into the insulating material of the electric core. In addition, the electric core body is fastened through arranging the inner concaves on the side wall of the metal shell, and extruding the periphery of the electric core by the bumps formed by the inner concave on the inner wall of the shell.
Description
Technical field
This creation belongs to the aluminium electrolytic capacitor product technical field, relates in particular to a kind of well-set aluminium electrolytic capacitor.
Background technology
At present, all fix with gel or pitch encapsulation for the fixing of large-scale aluminum electrolysis capacitor core bag, yet, adopt the encapsulation of gel or pitch fixedly to make the flammable organic substance deal of aluminium electrolytic capacitor increase, increased the risk of aluminium electrolytic capacitor; In addition, adopt gel or pitch easily to cause the weight of aluminium electrolytic capacitor to increase, and make the volume of aluminium electrolytic capacitor increase.And, the bad control of the loading of gel or pitch, and both are all high temperature melting fillings, have certain danger.And adopt gel or pitch also easily to cause the aluminium electrolytic capacitor conductive coefficient low, make the kernel thermal diffusivity of aluminium electrolytic capacitor bad, and then have influence on the life-span of aluminium electrolytic capacitor.
Owing to adopting the fixing defects that exists of gel or pitch encapsulation, therefore having now the part technology fixes by using aluminum hull cover plate compression core bag, but adopting the two sides clamping mode is kind of a test to the cover plate of phenolic aldehyde material, easily damage the cover plate of phenolic aldehyde material, the risk that leakage is arranged under long-term pressure stresses, and then have influence on life-span of capacitor, make the mechanism of capacitor firm not.
This shows, the equal Shortcomings of above-mentioned fixed form of the prior art therefore be necessary to research and develop, provides a kind of scheme that overcomes upper defective, so that a kind of well-set aluminium electrolytic capacitor to be provided.
Summary of the invention
For addressing the above problem, the purpose of this creation is to provide a kind of well-set aluminium electrolytic capacitor, and applicable to the environment of various large power, electrically source circuits, high-speed motion, vibrations, sound construction, stable, shock resistance is good.
For achieving the above object, the technical scheme of this creation is:
A kind of well-set aluminium electrolytic capacitor is cylindrical structure, includes battery core main body, package metals shell and package terminal cover plate; Wherein, the inner surface of described cover plate is provided with the cover plate reinforcement, and the bottom interior surface of metal shell is provided with the shell reinforcement; Be provided with a plurality of indents on the outer wall of metal shell, described indent forms salient point in the inwall of metal shell, with the battery core main body of extrusion metal shell coating, thereby makes the battery core main body fastening in the extruding of a plurality of salient points.
Further, also include seal washer and insulating gum cover, described seal washer is arranged at metal shell and cover plate junction, with effective cushion seal.
Further, described battery core main body includes the electrolytic paper between positive plate, negative plate, positive/negative plate, the lug sheet of drawing from positive/negative plate respectively.
Further, described positive plate, negative plate, electrolytic paper are wound into cylindric, to make the battery core main body; In the gap of described pole plate, electrolytic paper and lug sheet, absorption has electrolyte.
The cover plate reinforcement of the well-set aluminium electrolytic capacitor of this creation by the metal cover board inner surface is pressed in battery core insulation material, and the inner bottom part of metal shell adds the strong muscle of shell and equally also is pressed in battery core insulation material, thus reach link closely up and down fixing; In addition, by at the metal shell sidewall, indent being set, the salient point extruding battery core that the outer casing inner wall of indent forms is peripheral, thus fastening battery core main body.
