Embodiment Construction

[0026] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] refer to Figure 1-6 , an electrolytic capacitor, comprising a housing 1, the upper end of the housing 1 is provided with a closing mechanism, the closing mechanism includes a cover 2 sleeved on the upper end of the housing 1, and an elastic sleeve 7 is fixedly sleeved on the outer wall of the housing 1 , the upper end of the elastic sleeve 7 and the cover 2 are fixedly sleeved with a packaging sleeve, the elastic sleeve 7 can play a role of protection, shock absorption and buffering, and when the electrolytic capacitor heats up, the electrolytic capacitor will expand, and the elastic sleeve 7. The electrolytic capacitor can be wrapped to shrink the shell 1. The packaging sleeve can play an aesthetic role, and the packaging sleeve can be printed with words and patterns. The lower end of the cover 2 is fixedly connected to the ring plate 3, and the...

Abstract

The invention discloses an electrolytic capacitor including a housing, the upper end of the housing is provided with a closing mechanism, the inner bottom end of the shell is fixedly connected with acapacitor element, the capacitor element includes a first sealed housing fixedly connected to a bottom end of the housing, An anode aluminum foil and a cathode aluminum foil are wound inside the firstsealed shell, and the anode aluminum foil and the cathode aluminum foil are isolated by electrolytic paper. An anode plate is fixedly connected to the anode aluminum foil, a cathode plate is fixedlyconnected to the cathode aluminum foil, and leads are fixedly connected to the upper ends of the anode plate and the cathode plate. The advantages are: The invention avoids the problem that the aluminum foil is broken down after the electrolyte is evaporated and reduced, thereby prolonging the service life of the electrolytic capacitor, protecting the positive electrode line and the negative electrode line, and pulling out the positive electrode line and the negative electrode line for use through a limiting ball when the electrolyte is needed, thereby avoiding the problem of extra searching by the worker and reducing the energy of the worker.

Description

technical field [0001] The present invention relates to the technical field of electrolytic capacitors, in particular to an electrolytic capacitor. Background technique [0002] Electrolytic capacitors have electrolyte materials that store charges inside, which are divided into positive and negative polarities, similar to batteries, and cannot be reversed. The positive electrode is a metal substrate with an oxide film, and the negative electrode is connected to the electrolyte (solid and non-solid) through a metal plate. [0003] Nonpolar (bipolar) electrolytic capacitors adopt a double oxide film structure, which is similar to two polarized electrolytic capacitors formed by connecting two negative electrodes, and the two electrodes are two metal plates (both with oxide films) The two groups of oxide films are connected with electrolyte in the middle. Polar electrolytic capacitors usually play the role of power filter, decoupling (ǒu), signal coupling, time constant settin...
