Embodiment
In order to make the object of this creation, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this creation is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, connect integratedly, also can be removably connect; It can be the connection of two element internals; Can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, concrete condition can understand the concrete meaning of above-mentioned term in the utility model.
Shown in Fig. 1-Fig. 2, this creation slender type bolt type aluminium electrolytic capacitor comprises cover plate, shell and is coated on the core bag (not shown) in shell.Wherein, core bag includes positive pole paillon foil (not shown), negative pole paillon foil (not shown), electrolytic paper (not shown) and positive and negative electrode lead.Wherein, arrange electrolytic paper between positive pole paillon foil and negative pole paillon foil, positive and negative electrode lead is arranged on positive pole paillon foil and negative pole paillon foil respectively.Cover plate is provided with bolt type positive and negative electrode 101,102, positive and negative electrode lead correspondence connects described bolt type positive and negative electrode; The special high hole paper isolation of positive and negative electrode, positive pole paillon foil, negative pole paillon foil and electrolytic paper are wound into elongate strip pole profile by the orderly lamination of automatic mechanism, expose some length electrode leads, electrolyte is flooded after the dehumidifying of baking battery core, then with high heat conduction APP gel, fixed by cover plate, sealing rubber ring and packed by metal casing, form electrolytic capacitor.
Wherein, the utility model slender type bolt type aluminium electrolytic capacitor has big L/D ratio, and outward appearance is slender type, and its diameter is 18-50mm, and length is 130-260mm.The withstand voltage scope of this aluminium electrolytic capacitor is 200 ~ 500V, and capacity is 3300 μ ~ 5600 μ F, can be applicable to various high-power industry control power circuit, as high end audio, and frequency converter, ups power, outdoor moving power supply, charging pile for electric vehicle, robot.
Wherein, described cover plate is provided with the explosion-proof valve 103 of silica gel material, while explosion-proof, also can dialyses hydrogen out.Described slender type bolt type aluminium electrolytic capacitor is also provided with snap ring 110, for the installation of capacitor; In the utility model embodiment, described snap ring 110 is the ring grooves formed on capacitor metal shell 11, and it can also form the battery core of internal extrusion cladding in shell not only for the installation of capacitor, there is the effect that a fixed ring peridesm ties up, to play the effect of fixing battery core to battery core; In another embodiment of the utility model, described snap ring encloses around metal shell one bulge loop formed on capacitor metal shell.
Corresponding to described snap ring, the utility model slender type bolt type aluminium electrolytic capacitor also includes installs clip 12, and described clip is in " Ω " type or " U " type; When described snap ring is ring groove, accordingly, described clip 12 is provided with the projection of this ring groove of corresponding matching, thus installs fixing to closely cooperate firmly by the utility model slender type bolt type aluminium electrolytic capacitor.And when described snap ring is bulge loop, accordingly, described clip is provided with the groove of this bulge loop of corresponding matching, thus to closely cooperate, the utility model slender type bolt type aluminium electrolytic capacitor is installed fixing firmly.
In the utility model embodiment, described snap ring has two, is arranged at the central authorities of the first half of capacitor and the central authorities of latter half respectively; Correspondingly, described clip also has two.Certainly, in some cases, described snap ring also can only have one, or multiple, does not specifically limit; Correspondingly, the clip of respective number is also set.
Because this aluminium electrolytic capacitor is slender type list structure, electric current turnover electrode distalmost end path narrows down at present most fixed leveling, so have Low ESR high frequency tolerant characteristic, can tolerate large ripple current, electrolytic capacitor is not fragile, has very long useful life.
This creation slender type bolt type aluminium electrolytic capacitor has leptosomatic external appearance characteristic due to it, therefore installs the horizontal installation of employing, and center of gravity reduces; And general horizontal installation all can be put glue secondary and fixed, shock resistance is the strongest, can accomplish that physical property is perfectly safe.Horizontal installation simultaneously can reduce installing space greatly, has revolution formula impetus to power supply flattening, such as: the large power supply of frivolous thickness structure, and panel type large power, electrically source module, drawer type large power, electrically source unit, chip module power supply.
In various great-power electronic electric equipment products contracting body, flattening Design trend instantly, this creation novel fine elongated bolt type aluminium electrolytic capacitor can make elongate due to outward appearance, length has accomplished 130mm ~ 260mm, its alternative large-scale lug electrolytic capacitor in parallel, even can substitute superhuge bolt type electrolytic capacitor.
The foregoing is only the preferred embodiment of the utility model creation; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
