Copper conduct piece outer circle cooperation, and spare, the technique of metallization after ceramic inner and outer round surface is using metallization process are as follows: making pottery
The printing of porcelain inner and outer round surface or brushing molybdenum manganese alloy slurry, molybdenum manganese alloy slurry are 0.05- in the invasive depth of ceramic inner and outer round surface
0.07mm；The invasive depth of surface metalation ensure that the quality of welding on the basis of practicing every conceivable frugality precious metal.Processing
Good clean fixed plate or shell is lain against on high-temperature soldering mould, is then sequentially placed into the ceramic insulation embryo material of inside and outside hole metallization
In in fixed plate or shell, ceramic metallization embryo material outer circle and fixed plate or shell inner hole clearance fit, and in matching surface heap
Circular ring shape yellow gold solder is put, is finally put into copper conductor in ceramic embryo material inner hole, conductor is with ceramic insulation embryo material inner hole
Clearance fit stacks annulus yellow gold solder on a mating.After the above process is fully completed, above-mentioned assembly is well placed
Component be slowly sent into high temperature hydrogen furnace, elevated-temperature seal is welded.
To make ceramics insulator flawless, the utility model in high and low temperature alternative variation use above-mentioned technical proposal,
And annular groove is devised at ceramics insulator both ends, increase the extendable room when variation of insulator high/low temperature, it is ensured that ceramics
It is not squeezed and broken when insulator expands with heat and contract with cold or drawing crack, to guarantee the tightness and intensity of insulated mounting plate.
Using when: by fixed plate or case weld or be crimped on breaker, connector, contactor, relay, sensor
Or on the shell of switch, device outer case and insulated mounting plate are tightly connected, and play sealing function.Fixed plate or shell and ceramics are exhausted
Fixing seal is filled using the melting welding of silver-bearing copper welding method between edge body and copper conductor.Ceramics insulator outer circle silver-bearing copper welding surface with
It is welded after metallizing between fixed plate or shell for ceramics insulator outer round surface with fixed plate or shell high temperature filler；It is ceramic exhausted
It is filled out after metallizing in edge body between hole silver-bearing copper welding surface and copper conductor for ceramics insulator outer round surface with copper conductor high temperature
Welding is filled, sealing function is played.
The utility model has the advantages that have high terminal strength, ceramic insulation sealing, high conductivity, will not magnetizing effect properties of product；Pottery
For porcelain insulator inner and outer round surface with copper conductor and fixed plate or case weld after metalized, weld strength is good；It is fixed
The setting of position hanging platform ensure that the precision of wiring.
