Description

Capacitor

Technical field

The utility model relates to a kind of capacitor.

Background technology

The capacitor that in household electrical appliance and light fixture, uses, comprise aluminium shell and place the interior capacity cell of shell, capacity cell comprises volume core, capacitor element and two electrode end surfaces, the cross section of capacitor element is annulus, the middle part of capacitor element is the volume core, the two ends of capacitor element connect respectively two electrode end surfaces, and two electrode end surfaces connect the electric wire of drawing separately.Mainly there is following defective in existing capacitor: 1. insulation effect is poor between the circuit block of the interior the two poles of the earth of capacitor, easy puncture short, cause the high temperature explosion, even even burn 2. when power supply is cut off, be stored in the situation that voltage still exists and the capacitor case insulation effect is poor in the capacitor element, if the user touches this capacitor, then easily produce the danger of electric shock human body; 3. when the capacitor case material is aluminium material, easily produce distortion during bump, destroy capacitor element, also easily cause capacitor short-circuit, cause the high temperature explosion, even burning.

Summary of the invention

Goal of the invention of the present utility model is the deficiency that exists in order to overcome existing capacitor, and a kind of novel structure is provided, and insulation effect is good, not yieldingly causes short circuit, has the discharge prevention function, has effectively avoided the danger of electric shock human body, safe capacitor.

In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:

Capacitor, comprise shell, rigid insulation inner bag, Insulation stopping and capacity cell, the rigid insulation inner bag is equipped inside the shell, and capacity cell is in the rigid insulation inner bag, and the Insulation stopping place in the enclosure and be filled between rigid insulation inner bag and the capacity cell; Described capacity cell comprises capacitor element, discharge resistance, volume core, two arrays of electrodes end face and two draw wire up and down, the capacitor element two ends connect respectively up and down two arrays of electrodes end face, the two arrays of electrodes end face connects respectively the wire of drawing separately up and down, the volume core is fitted on the annular inboard face of capacitor element, and discharge resistance is in parallel with capacitor element.

As preferably, described discharge resistance is in the capacitor element outside, and the discharge resistance two ends connect up and down two arrays of electrodes end face by wire.

As preferably, also comprise being in two outer binding posts of housing, draw wire and connect respectively and be located at two outer binding posts of housing for described two.

As preferably, also comprise the equipped plug that is fixed on the housing outer wall, draw the outer equipped plug of wire connection housing for described two.

Adopted the capacitor of technique scheme; this capacitor comprises shell, rigid insulation inner bag, Insulation stopping and capacity cell; the rigid insulation inner bag is equipped inside the shell; capacity cell is in the rigid insulation inner bag; the rigid insulation inner bag is hard, not yielding with the shell support, novel structure; the parts of capacitor for voltage protection inside are not destroyed, and prevent short circuit or electric leakage.The Insulation stopping place in the enclosure and be filled between rigid insulation inner bag and the capacity cell, insulation effect is good.Capacity cell comprises capacitor element, discharge resistance, volume core, two arrays of electrodes end face and two draw wire up and down, and the volume core is fitted on the annular inboard face of capacitor element, and discharge resistance is in parallel with capacitor element.Behind dump, can fall the tele-release that is stored in the capacitor element in a short period of time, be that capacitor element is as power supply, discharge resistance is as load, form the closed-loop path and discharge, the voltage of capacitor element is reduced to zero, avoided because capacitor element is charged, the danger of electric shock human body is safe behind the human body touch.In a word, the advantage of this capacitor is: novel structure, and insulation effect is good, not yieldingly causes short circuit, has the discharge prevention function, and the danger of the human body of effectively avoiding shocking by electricity is safe, long service life.
