Abstract
The utility model discloses an aluminium electrolytic capacitor, wherein the external diameter of the aluminium electrolytic capacitor is 22 mm; a lead is in the form of a guide pin; the guide pin comprises an aluminium wire, a middle section and a flat part integrally connected in turn; the aluminium wire of the guide pin passes through a rubber plug; the middle section is clamped in the rubber plug; the guide pin is fixed by extruding the middle section through the rubber plug; and the diameter of the aluminium wire is 1 mm. According to the utility model, aiming at the electrolytic capacitor with the diameter of 22 mm, the guide pin is still adopted; proper sizes of the aluminium wire and the middle section are found out through repetitive researches and tests; therefore, the production cost can be greatly reduced; simultaneously, firmness and intensity of the lead are ensured.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor, and particularly a kind of diameter is 22 millimeters aluminium electrolytic capacitor.
Background technology
Electrolytic capacitor refers to adopt anode oxidation method to generate the skim oxide as dielectric at metallic surfaces such as aluminium, tantalum, niobium, titaniums, the capacitor that consists of as negative electrode with electrolyte.And aluminium electrolytic capacitor has following 3 large advantages: 1, the capacitance of unit volume is very large, than the electric capacity large tens of other kind to hundreds of times; 2, specified capacity can accomplish very large, can accomplish easily several ten thousand μ f even a few f(but can not with the electric double layer capacitance ratio); 3, other kind of cost ratio has overwhelming dominance, because the composition material of electrochemical capacitor all is common industrial materials, such as aluminium etc.The equipment of making electrochemical capacitor also all is common industrial equipment, can large-scale production, and cost is relatively low.So use extensively.During less than 22 millimeters, lead-in wire adopts the guide pin structure to existing aluminium electrolytic capacitor, thereby production cost is very low at diameter, but when more than or equal to 22 millimeters, for the firm degree that guarantees to go between, all can only adopt the structure of capillary, greatly increased production cost.
The utility model content
The purpose of this utility model provides on a kind of basis guaranteeing lead-in wire intensity, and the diameter that is used for that can the decrease production cost is 22 millimeters electrolytic capacitor.
The technical scheme that realizes the utility model purpose is a kind of aluminium electrolytic capacitor, and overall diameter is 22 millimeters, and lead-in wire adopts the guide pin structure; Described guide pin comprises aluminum steel, interlude and the plat part that connects as one successively; The aluminum steel of described guide pin passes plug, and interlude is arranged in the plug, and guide pin is fixed by plug extruding interlude; The diameter of described aluminum steel is 1 millimeter.
The diameter of described interlude is 2.5 millimeters.
Adopted technique scheme, the utlity model has following beneficial effect: the utility model is that 22 millimeters electrolytic capacitor still adopts the guide pin structure for diameter, by repeatedly studying and testing, find the size of suitable aluminum steel and interlude, thereby can the decrease production cost guarantee simultaneously the firmness and the intensity that go between, the 0.2-0.3 unit of the production cost of single electrolytic capacitor during from the capillary structure is reduced to present 0.04-0.05 unit, greatly saved production cost.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is the novel contour structures schematic diagram of this use.
The guide pin structural representation that Fig. 2 adopts for lead-in wire.
Attached number in the figure is:
Lead-in wire 1, aluminum steel 11, interlude 12, plat part 13, plug 2.
Embodiment
See Fig. 1 and Fig. 2, the profile of the aluminium electrolytic capacitor of the present embodiment as shown in the figure.Overall diameter is 22 millimeters, and lead-in wire 1 adopts the guide pin structure.See Fig. 2, guide pin is aluminium material, comprises the aluminum steel 11, interlude 12 and the plat part 13 that connect as one successively.When assembling, the aluminum steel 11 of guide pin passes plug 2, and interlude 12 is arranged in the plug 2, plat part 13 since diameter much larger than the other end of therefore staying plug 2 greater than interlude 12, extruding plug 2,12 of the interludes of guide pin are fixed in the plug 2, thereby guide pin is fixed.Existing diameter is that the diameter of capillary of 22 millimeters aluminium electrolytic capacitor is 0.8 millimeter, but advanced validation trial, adopt the aluminum steel structure of guide pin structure tentatively to guarantee the firmness and the intensity that go between greater than 0.8 millimeter ability, and the diameter of working as aluminum steel 11 is 1 millimeter, when the diameter of interlude 12 was 2.5 millimeters, the diameter that can make employing guide pin structure was that lead-in wire firmness and the intensity of 22 millimeters aluminium electrolytic capacitor all meets the requirements.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
