Abstract

The utility model provides a capacitor comprising an anode foil, a cathode foil and electrolytic paper wrapping the capacitor, wherein at least two leading-out strips are respectively installed on the anode foil and the cathode foil. By respectively installing at least two leading-out strips on the anode foil and the cathode foil, the loss and heating quantity of the capacitor are effectively reduced, and the quick charge and discharge capacity of the capacitor is improved. Hence, the capacitor better satisfies the use requirement of such equipment as welding machines, UPS power supplies and frequency converters.

Description

Capacitor

Technical field

The utility model relates to a kind of capacitor.

Background technology

, social demand amount increasingly mature along with device fabrication technology such as DC welder, frequency converter, ups powers also increases sharply, and its quality is had higher requirement.The aluminium electrolytic capacitor that uses in these equipment, its quality requirement is higher.

Its inside of some general capacitors is single to drawing bar at present, and when using this capacitor, owing to reach tens amperes by the electric current of capacitor, its loss is big and the fast charging and discharging ability is low, easily causes it to generate heat seriously, produces early stage thermal failure.

The utility model content

For this reason, technical problem to be solved in the utility model is: provide a kind of capacitor, by the improvement of its internal structure, to reduce the loss and the caloric value of capacitor, improve capacitor fast charging and discharging ability, better meet the instructions for use of welding machine, ups power and these equipment of frequency converter.

So the utility model provides a kind of capacitor, comprise cathode foil, anode foil and the electrolytic paper that holds it, wherein, on cathode foil and anode foil, be respectively provided to few two leads.

Described lead is riveted on described cathode foil and the anode foil.

Capacitor described in the utility model, by on cathode foil and anode foil, being respectively provided to few two leads, make that the loss and the caloric value of capacitor are all effectively reduced, improve capacitor fast charging and discharging ability, better met the instructions for use of welding machine, ups power and these equipment of frequency converter.

Description of drawings

Fig. 1 is the described capacitor core group internal structure of a utility model embodiment schematic diagram;

Fig. 2 is provided with structural representation for lead on described cathode foil of Fig. 1 and the anode foil;

Fig. 3 is the another schematic diagram of the described capacitor core group internal structure of the utility model embodiment.

Embodiment

Below, in conjunction with the accompanying drawings the utility model is described in detail.

As Fig. 1, Fig. 2, shown in Figure 3, present embodiment provides a kind of capacitor, and it comprises: cathode foil 11, anode foil 12, hold the electrolytic paper 13 of cathode foil 11 and anode foil 12 and be separately positioned on cathode foil and anode foil on lead 14 and lead 15.

The capacitor that present embodiment provides, for effectively reducing the loss and the caloric value of capacitor, improve capacitor fast charging and discharging ability, better meet the instructions for use of welding machine, ups power and these equipment of frequency converter, lead 14 and lead 15 are set at least 2.

Described

lead

14,15 is riveted on described cathode foil and the anode foil.

In sum, the described capacitor of present embodiment, by on cathode foil and anode foil, being respectively provided to few two leads, make that the loss and the caloric value of capacitor are all effectively reduced, improve capacitor fast charging and discharging ability, better met the instructions for use of welding machine and these equipment of frequency converter.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.

Claims

1. a capacitor comprises cathode foil, anode foil and the electrolytic paper that holds it, it is characterized in that, is respectively provided to few two leads on cathode foil and anode foil.

2. capacitor according to claim 1 is characterized in that described lead is riveted on described cathode foil and the anode foil.
