Anti-splashing cover cap and anti-splashing capacitor

The invention relates to the technical field of capacitors, and discloses an anti-splashing cover cap and an anti-splashing capacitor. The anti-splashing cover cap comprises a cover body, the cover body is provided with an inner cavity, and the cover body is provided with a pressure relief hole connected to the inner cavity; a heat dissipation structure is arranged in the inner cavity and is provided with a plurality of hole structures convenient for adsorbing an electrolyte; and an explosion-proof plug used for releasing a gas is installed in the pressure relief hole, and a pressure relief channel used for exposing the pressure relief hole is arranged in the heat dissipation structure. Due to a fact that the heat dissipation structure separates the electrolyte from the gas, a mode of absorbing the electrolyte and releasing the gas is adopted, the electrolyte cannot be sprayed out from an upper portion of the capacitor, and a problem that the electrolyte pollutes a circuit board to cause short circuit is solv
