Further say, ceramic package's bottom be provided with the through-hole, the electrically conductive pin of components and parts body passes through-hole to ceramic package's outside, the through-hole outside is provided with the recess, electrically conductive pin fixed with ceramic package through the filler material that sets up in the recess.

Still further say, ceramic case's open-top's inner wall on set up the notch, ceramic lid when on ceramic case with the notch form the pressure release mouth. The notch is arranged on the inner wall of the ceramic shell in a step structure, and when the ceramic cover covers the ceramic shell, the step structure and the ceramic cover form a staggered air duct for pressure relief of the inner cavity of the ceramic shell.

Still further say, pottery lid when ceramic package goes up form the sink groove at the ceramic package top, the sink groove in be provided with and hinder fuel.

Still further say, the both sides of components and parts body be provided with electrically conductive electrode respectively, electrically conductive pin pass through electrically conductive electrode and this body coupling of components and parts.

Still further say, the outside parcel of components and parts body have insulating encapsulated layer.

Still further, the inner cavity of the ceramic shell of the utility model is provided with flame-retardant filler.

The utility model has the advantages that the defects in the background technology are overcome, the ceramic shell and the ceramic cover are made of the same material, the ceramic protection is formed, the explosion prevention and the combustion isolation of all directions are carried out on the internal components, and the components and the board and other elements on the board are protected; the pressure relief port formed by the ceramic shell and the ceramic cover can be used for internal pressure relief; and fuel resistance is added outside the ceramic cover to further improve the safety performance.
