Abstract

The utility model discloses a novel aluminum electrolytic capacitor, including an aluminum shell and a core package, wherein the core package is manufactured by winding positive electrode foil, negative electrode foil, electrolytic paper, aluminum stem and outgoing lines. The core package is immersed by an electrolyte, and the top of the core package is provided with a rubber plug for sealing. The outgoing lines are fixed on the rubber plug. An insulating sleeve is arranged outside the aluminum shell. The outgoing lines are of tin-coated steel wires or copper-coated steel wires. The core package is provided with the rubber plug for sealing on the top thereof and thus is good in sealing, and the aluminum shell is outside provided with an insulating sleeve, so the aluminum electrolytic capacitor has low electric leakage characteristics, can withstand a temperature up to 125 DEG C, has a load life of more than 3,000 hours at higher temperatures, and is especially suitable for energy-saving lamps.

Description

A kind of New Type Aluminum Electrolytic Capacitor

Technical field

The utility model relates to a kind of electric elements, particularly a kind of aluminium electrolytic capacitor

Background technology

The core bag of existing aluminium electrolytic capacitor is reeled by cathode foil, anode foil, electrolytic paper and lead-out tablet and is made, the heat that the core job contract of the electrolytic capacitor of this structure produces when doing mainly passes to the inwall of aluminum hull by the air dielectric of interiors of products, the efficient of heat transfer mode is very low, and heat-resisting ability is relatively poor.

And used aluminium electrolytic capacitor wants cube little in the ballast of electricity-saving lamp, and is anti-than large ripple current, works reliably and with long-term under up to 90-110 ℃ of condition in ambient temperature, and therefore existing aluminium electrolytic capacitor also can't satisfy the instructions for use of electricity-saving lamp.

Summary of the invention

The purpose of this utility model provides a kind of long-service-life aluminum electrolytic capacitor for energy-saving lamp.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of New Type Aluminum Electrolytic Capacitor, comprise aluminium shell-and-core bag, described core bag is reeled by cathode foil, anode foil, electrolytic paper, aluminium stalk and lead-out wire and is made, core comprises and soaks that the top is provided with the sealing plug behind the electrolyte, described lead-out wire is fixed on the plug, and described aluminum hull is arranged with insulating sleeve outward.

Wherein, described lead-out wire is zinc-plated steel wire or copper-plated steel wire.

The beneficial effects of the utility model are: core bag top is provided with sealing and uses plug, and good airproof performance, aluminum hull are arranged with insulating sleeve outward, has low electric leakage feature, can bear the high temperature up to 125 ℃, the load life test can reach more than 3000 hours under higher temperature, was particularly suitable for electricity-saving lamp and used.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is expanded view of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to Fig. 1, shown in Figure 2, the utility model discloses a kind of New Type Aluminum Electrolytic Capacitor, comprise aluminum hull 6 and core bag 5, described core bag 5 is reeled by cathode foil 1, anode foil 2, electrolytic paper 3, aluminium stalk and lead-out wire 4 and is made, the top is provided with sealing plug 7 behind the core bag 5 impregnation electrolyte, described lead-out wire 4 is fixed on the plug 7, is arranged with insulating sleeve 8 outside the described aluminum hull 6, and described lead-out wire 4 is zinc-plated steel wire or copper-plated steel wire; The utility model core bag top is provided with sealing plug 7, good airproof performance, the aluminum hull 6 outer insulating sleeves 8 that are arranged with, has low electric leakage feature, can bear the high temperature up to 125 ℃, the load life test can reach more than 3000 hours under higher temperature, was particularly suitable for electricity-saving lamp and used.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
