Abstract

Disclosed is a high-capacity filtering capacitor which relates to the technical field of capacitors. The high-capacity filtering capacitor includes a casing, core groups and electrodes. A plurality of connecting wires are connected evenly with end faces of the core groups. A plurality of electrodes are arranged on the casing and each connecting wire is connected with a corresponding electrode. The lead-out wires of the end faces of the core groups of the high-capacity filtering capacitor are evenly distributed so that heterozygous inductances are greatly reduced. At the same time, the plurality of electrodes are arranged on the casing so that a good flow-equalizing effect is achieved on ultraharmonics.

Description

A kind of large capacity filtering capacitor

Technical field

The utility model relates to the capacitor technology field, relates in particular to a kind of large capacity filtering capacitor.

Background technology

Capacitor is a kind of electronic product commonly used, capacitor general main comprise shell, fixing in the enclosure fuse and the electrode that is electrically connected to fuse, capacitor is generally fuse and is connected on two electrodes and is encapsulated in a rectangular structure, electrode directly is connected with the fuse end face and stretches out outside cuboid, the shortcoming of this capacitor is: capacitor is when being made into large capacity filter capacitor, due to the internal structure complexity, the more assorted living inductance of the many easily generations of connecting line, affect capacitor performance.

Summary of the invention

The purpose of this utility model is to provide a kind of large capacity filtering capacitor, and its electrode outlet line is evenly distributed, and greatly reduces assorted generation of giving birth to inductance, and for high order harmonic component, current balance function is arranged.

In order to solve existing problem in background technology, the utility model is by the following technical solutions: it comprises shell, core group, electrode, described core group end face is connected with several connecting lines uniformly, on described shell, is provided with a plurality of electrodes, and each connecting line is connected with corresponding electrode.

The utility model is owing on each end face of core group, being connected with uniformly a plurality of connecting lines, each connecting line is connected with the electrode on shell, and then be connected with external circuit by electrode, make the electric current on connecting line between capacitor end surface different directions occur, and electrode is evenly distributed, therefore the inductance that produces is cancelled out each other, thereby must reduce to greatest extent the generation of assorted living inductance, simultaneously owing to adopting a plurality of electrode lead-out modes to make product that the effect of current-sharing be arranged for high order harmonic component.

The utility model it adopt core group end face evenly to connect a plurality of connecting lines, and connecting line is connected with corresponding electrode, make the lead-out wire of core group end face be evenly distributed, greatly reduce assorted generation of giving birth to inductance, a plurality of electrodes that arrange on shell simultaneously, have current balance function preferably for high order harmonic component.
