Technical Field

[0002] Electronic ceramic devices are a type of electronic component manufactured using the electrical, mechanical, and high-temperature properties of ceramic materials. These devices are widely used in various fields, including electronics, power, communications, automotive, and medical. High-insulation, pressure-resistant ceramic shell structures are a superior material used in high-voltage and high-voltage environments, providing important protection and isolation for electronic devices.

[0003] After searching, Chinese patent announcement number: CN220171928U discloses an insulating suit shell, which relates to the field of capacitor protection. The utility model includes a capacitor, and a protective mechanism is set on the outside of the capacitor, and the protective mechanism includes a lower shell. The utility model sets a protective mechanism, including a lower shell, an upper shell, an insulating sleeve, a lower porcelain shell, an upper porcelain shell, an insulating layer, a moisture-proof layer, and a sealing layer. After the capacitor is installed on the lower porcelain shell, the capacitor is fixed and protected by the lower porcelain shell and the upper porcelain shell, and the lower porcelain shell and the upper porcelain shell have high insulation and heat resistance, so they can effectively protect the capacitor. In addition, in order to prevent the lower shell and the upper shell from getting wet and causing the capacitor to get wet, two layers of insulating layer and moisture-proof layer are set inside the sealing layer. The insulating layer can prevent leakage, and the moisture-proof layer is made of resin particles, so it has a relatively good water absorption and moisture-proof effect.
