Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitor packaging, in particular to a packaging structure for preventing electrolytic capacitors from regenerating voltage and preventing vibration. Background Art
[0002] Capacitor, also known as capacitor, is a passive device used to hold electric charge. When the aluminum electrolytic capacitor is aged and voltage is applied to the medium, the reaction of the medium causes the migration of electrons inside the medium, thereby generating an induced electric field inside the medium. Its direction is opposite to the voltage direction on the surface of the medium. This imagination is called polarization reaction. When the aging is completed, the discharge will make the voltage between the two terminals zero. After it is left open for a period of time, a voltage is generated at the two terminals, which is the regeneration voltage. The voltage of the electrolytic capacitor will rise after being placed for a long time. At a temperature of 25°C, it may reach 10% of the voltage value before discharge in 100s-1000s. At higher temperatures, the residual voltage will be higher. For high-voltage aluminum electrolytic capacitors, the residual voltage may reach 40-50V or even higher. This will cause accidental discharge, especially electric shock to materials and people, leading to accidents.
[0003] However, the existing capacitor packaging structure cannot effectively prevent the capacitor regeneration voltage discharge, which may easily cause safety hazards; therefore, we propose a packaging structure that prevents electrolytic capacitor regeneration voltage and vibration, in order to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging structure for preventing electrolytic capacitor regeneration voltage and vibration, comprising a packaging box body, wherein a box cover is installed at the upper end of the packaging box body;
