Description
Technical Field
[0001] The utility model relates to the field of aluminum electrolytic capacitors, and more specifically, to a cover plate of an aluminum electrolytic capacitor. Background Art
[0002] Aluminum electrolytic capacitors are essential components for various electronic product terminals and play a vital role in industrial frequency conversion, power supply and other applications. They are composed of a cover, an aluminum shell, a sleeve, a gasket, and an element, and are installed by manual or mechanical cover.
[0003] The existing aluminum electrolytic capacitor has a simple cover structure, which can only play a sealing role, and cannot play a positioning role for the core package. To fix the core package, it is necessary to inject black glue into the shell after placing the core package into the shell to fix the core package.
[0004] When using the black glue for packaging, the black glue needs to be heated, which consumes a lot of energy. The black glue potting is costly and the process is complicated. After being scrapped, it is not environmentally friendly and the heat dissipation effect is not ideal. Therefore, some aluminum electrolytic capacitors, in order to ensure the fixation of the core package, achieve the positioning effect by setting a raised positioning block on the inner side of the cover plate. However, this positioning structure is in a fixed state and cannot be well positioned according to the installation situation of the core package, which is prone to the situation of insufficient fixation or excessive fixation.
[0005] At the same time, the existing aluminum electrolytic capacitor has a simple internal structure with many gaps, and the entire aluminum electrolytic capacitor has a low compressive resistance, which makes the aluminum electrolytic capacitor easily damaged when squeezed, thereby causing the aluminum electrolytic capacitor to be unusable. However, the existing aluminum electrolytic capacitor cannot solve this problem well through its cover structure.
