The side for stating sealing resin is provided with metal pedestal, circumferentially arranged with some laths in the metal pedestal, between two pieces of metal pedestals
The melt for being additionally provided with and being set around the sheet metal in sheet metal, the housing is fixed with, the melt includes close
The fluxing layer of the sheet metal and the alloy-layer being arranged on the outside of fluxing layer.
Further, the housing is glass shell.
Further, the insulating barrier is made of pvc material.
Further, the lath is made of PA46 materials.
Further, the sheet metal is provided with some pores.
Further, the two ends of the sheet metal are with being arranged in the sealing resin, ceramics insulator and metal pedestal
Wire be connected.
The beneficial effects of the utility model：The present apparatus is provided with lath in metal pedestal, while provided with punctulate gold
