Abstract
The utility model discloses an aluminium electrolytic capacitor with an improved structure; the aluminium electrolytic capacitor comprises an aluminium cylinder and a capacitor core bag; the capacitor core bag comprises an anode aluminium foil, a cathode aluminium foil, an anode guide line, a cathode guide line and at least three electrolytic paper layers positioned between the anode aluminium foil and the cathode aluminium foil; the anode guide line and the cathode guide line are respectively provided with fixed tongue portions, and the fixed tongue portions are respectively riveted with corresponding anode aluminium foil and cathode aluminium foil; an upper end portion of the anode aluminium foil extends above the electrolytic paper, and a lower end portion of the anode aluminium foil does not exceed a bottom end face of the electrolytic paper; and a lower end portion of the cathode aluminium foil extends below the electrolytic paper, and an upper end portion of the cathode aluminium foil does not exceed a top end face of the electrolytic paper. Because the aluminium foil has much better heat conduction effect when compared with the electrolytic paper, so parts of the anode aluminium foil and the cathode aluminium foil exposed outside the electrolytic papers can fast radiate the heat of the capacitor core bag, thereby effectively preventing a disadvantage that electrolyte is dried by accumulated heat; and the aluminium electrolytic capacitor with the improved structure is good in heat radiation effect and long in service life.
Description
Technical field
The utility model relates to the capacitor technology field, relates in particular to a kind of structure improved aluminium electrolytic capacitor.
Background technology
As a kind of important capacitance component, aluminium electrolytic capacitor has been widely used in the electron trade; Wherein, aluminium electrolytic capacitor has generally comprised anodal aluminium foil, negative pole aluminium foil, electrolytic paper, positive wire and negative wire.
For avoid anodal aluminium foil and negative pole aluminium foil in winding process owing to contacting the phenomenon that is short-circuited, the width of the general more anodal aluminium foil of the width of the electrolytic paper of existing aluminium electrolytic capacitor, negative pole aluminium foil is big; Because aluminium electrolytic capacitor can produce heat in the course of work of reality, too much accumulation of heat can cause electrolyte to be caused aluminium electrolytic capacitor to lose efficacy by oven dry; Yet there is the heat radiation defect of bad in said structure, has seriously influenced the useful life of aluminium electrolytic capacitor.
Summary of the invention
The purpose of this utility model is to provide a kind of structure improved aluminium electrolytic capacitor, this structure improved aluminium electrolytic capacitor good heat dissipation effect and long service life at the deficiencies in the prior art.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of structure improved aluminium electrolytic capacitor, include the aluminium cylinder and be flush-mounted in the interior capacitor core bag of aluminium cylinder, the capacitor core bag includes anodal aluminium foil and negative pole aluminium foil, be equiped with at least three layers of electrolytic paper between anodal aluminium foil and the negative pole aluminium foil, positive wire is equipped with in anodal aluminium foil riveting, negative wire is equipped with in the riveting of negative pole aluminium foil, and positive wire and negative wire are respectively arranged with fixedly tongue, and fixedly tongue is riveted with corresponding anodal aluminium foil and negative pole aluminium foil respectively; The upper end of anodal aluminium foil extends the top of electrolytic paper, and the bottom of anodal aluminium foil does not exceed the lower surface of electrolytic paper, and the bottom of negative pole aluminium foil extends the below of electrolytic paper, and the upper end of negative pole aluminium foil does not exceed the upper surface of electrolytic paper.
The beneficial effects of the utility model are: a kind of structure improved aluminium electrolytic capacitor described in the utility model, it includes the aluminium cylinder and is flush-mounted in the interior capacitor core bag of aluminium cylinder, the capacitor core bag includes anodal aluminium foil and negative pole aluminium foil, be equiped with at least three layers of electrolytic paper between anodal aluminium foil and the negative pole aluminium foil, positive wire is equipped with in anodal aluminium foil riveting, negative wire is equipped with in the riveting of negative pole aluminium foil, positive wire and negative wire are respectively arranged with fixedly tongue, and fixedly tongue is riveted with corresponding anodal aluminium foil and negative pole aluminium foil respectively; The upper end of anodal aluminium foil extends the top of electrolytic paper, and the bottom of anodal aluminium foil does not exceed the lower surface of electrolytic paper, and the bottom of negative pole aluminium foil extends the below of electrolytic paper, and the upper end of negative pole aluminium foil does not exceed the upper surface of electrolytic paper.Because the heat-conducting effect of aluminium foil is well more a lot of than electrolytic paper, be exposed to electrolytic paper outer anodal aluminium foil part and negative pole aluminium foil part and apace the heat of capacitor core bag dispelled the heat away, and then avoided thermal accumlation effectively and the defective that causes electrolyte to be dried.Comprehensive above-mentioned situation the utlity model has the advantage of good heat dissipation effect and long service life as can be known.
Description of drawings
Utilize accompanying drawing to come the utility model is further detailed below, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model.
In Fig. 1, include:

5---electrolytic paper 6---positive wire
7---negative wires 8---are tongue fixedly.
Embodiment
Come the utility model is described below in conjunction with concrete execution mode.
As shown in Figure 1, a kind of structure improved aluminium electrolytic capacitor, include aluminium cylinder 1 and be flush-mounted in capacitor core bag 2 in the aluminium cylinder 1, capacitor core bag 2 includes anodal aluminium foil 3 and negative pole aluminium foil 4, be equiped with at least three layers of electrolytic paper 5 between anodal aluminium foil 3 and the negative pole aluminium foil 4, positive wire 6 is equipped with in anodal aluminium foil 3 rivetings, negative wire 7 is equipped with in 4 rivetings of negative pole aluminium foil, positive wire 6 and negative wire 7 are respectively arranged with fixedly tongue 8, and fixedly tongue 8 is riveted with corresponding anodal aluminium foil 3 and negative pole aluminium foil 4 respectively; The upper end of anodal aluminium foil 3 extends the top of electrolytic paper 5, and the bottom of anodal aluminium foil 3 does not exceed the lower surface of electrolytic paper 5, and the bottom of negative pole aluminium foil 4 extends the below of electrolytic paper 5, and the upper end of negative pole aluminium foil 4 does not exceed the upper surface of electrolytic paper 5.
Because the heat-conducting effect of aluminium foil is good more a lot of than electrolytic paper 5, be exposed to electrolytic paper 5 outer anodal aluminium foil 3 parts and negative pole aluminium foil 4 parts and apace the heat of capacitor core bag 2 dispelled the heat away, and then avoided thermal accumlation effectively and the defective that causes electrolyte to be dried.
Comprehensive above-mentioned situation the utlity model has the advantage of good heat dissipation effect and long service life as can be known.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
