Abstract
A large volume aluminum electrolytic capacitor comprises a core, an outer shell, an upper cover, a terminal, a filling material, and a lead-out foil, characterized in that the inner end of the terminal thereof is provided with a groove which increases the contacting surface of the lead-out foil and the terminal and reduces the contacting resistance. Thereby the tangent value of the loss angle of the capacitor is small and the capability is advanced. And the filling material thereof employs the black glue and has the advantages that the black glue has good heat dissipation and flame resistant and doesn't have the poison gas overflow compared with the asphaltum, thereby the utility model is safe and reliable.
Description
Technical field
The utility model relates to electronic component, particularly a kind of big capacity aluminium electrolytic capacitor.
Background technology
Automobile audio is connected in parallel on the two ends of storage battery with a farad level aluminium electrolytic capacitor, can make stereo set big dynamically, under the moment high-power output situation, its supply voltage remains unchanged substantially, thereby has guaranteed the tonequality of automobile audio.Existing electrolytic capacitor (as shown in Figure 1), inserts 05 between its fuse 1 and the shell 2 adopts the petroleum asphalt insulating cement, and pitch can burn when high temperature, naked light, and produces toxic gas, thermal diffusivity is also poor, and this is never safe to the electronic vehicle product; And the paper tinsel 6 of drawing of its fuse 1 to be inlaid in I shape the inner 07 of terminal 04 thinner, the contact resistance between fuse 1 and the terminal 04 is just bigger, then the loss tangent of capacitor (being equivalent series resistance ESR) is bigger, properties of product are not high.
Summary of the invention
The utility model is in order to solve the inflammable and bigger existing technical problem of loss tangent of existing aluminium electrolytic capacitor heating, and a kind of safe and reliable, big capacity aluminium electrolytic capacitor that loss tangent is less is provided.
According to above-mentioned purpose, the utility model provides a kind of big capacity aluminium electrolytic capacitor, and by fuse, shell, loam cake, terminal, inserts, draw paper tinsel and constitute, wherein terminal is inner fluted, and inserts adopts black glue.
Therefore the utility model has the heat radiation advantage that fire-retardant, no poison gas releases, loss tangent is little, thereby has guaranteed that hoot device is safe and reliable, tonequality is graceful owing to taked above technical measures.
Description of drawings
Fig. 1 is the structural representation of existing big capacity aluminium electrolytic capacitor.
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, a kind of big capacity aluminium electrolytic capacitor, by fuse 1, shell 2, loam cake 3, terminal 4, inserts 5, drawing paper tinsel 6 constitutes, capacitor body 1 be one by aluminium foil, at interval coiling and flooded the cylinder of electrolyte of insulation liner layer, shell 2 is aluminium matter drums, between fuse 1 and shell 2, inject inserts 5 and fix fuse 1, inserts 5 adopts the black glue of electronic product special use, black glue compare with pitch have fire-retardant, thermal diffusivity is good, the advantage that no poison gas releases, safe and reliable, draw paper tinsel 6 the positive and negative two-stage of aluminium foil in the fuse 1 is connected with the inner 7 setting-ins of two terminals 4, the outer end by terminal 4 can be connected to aluminum capacitor in the application circuit.Another characteristics of the present utility model are that terminal 4 and reeded inner 7 its overall dimensions are relatively large, have reduced the contact resistance of drawing paper tinsel 6 and inner 7 like this, have also reduced the loss tangent of capacitor, have improved reliability of products.
