The utility model discloses carry out pottery and metal material effectively compound, both satisfied high power microwave assembly's operation requirement, improved pulse power and pulse voltage again, still have small, light in weight, simple and easy, the good advantage of the high and insulating nature of assembly precision of structure simultaneously.
Description
Technical field
The utility model relates to a kind of ceramic shaft for High-Power Microwave generating means.
Background technology
High-Power Microwave generating means domestic at present, the better metal parts of connecting axle many employings insulation property of its inside, although the precision of metal parts and intensity can meet instructions for use, but under high voltages, discharge between electrode meeting and metal parts, and then have impact on the raising of whole pulse voltage and pulse power, the intrinsic electric conductivity of metal parts limits High-Power Microwave generating means to high power development, is therefore necessary to propose to improve.
Utility model content
The technical problem that the utility model solves: a kind of ceramic shaft for High-Power Microwave generating means is provided, pottery and metal material is carried out effective compound, has both met the instructions for use of high-power microwave assembly, turn improve pulse power and pulse voltage.
The technical solution adopted in the utility model: for the ceramic shaft of High-Power Microwave generating means, there is ceramic body, the same axis of described ceramic body excircle is shaped with multiple blind hole, equal metallizing layer at the bottom of described blind hole inwall and hole, described metal layer is coated with nickel dam I, the cut down post that excircle and bottom are all coated with nickel dam II to insert in blind hole and is welded as a whole after filling solder between nickel dam II and nickel dam I, and described cutting down on post is shaped with screw.
Further, described ceramic body adopts 95% aluminium oxide ceramics to make.
Further, the diameter of described ceramic body is 12-15mm, and length is 200-210mm.
Further, the same axis of described ceramic body excircle is shaped with 3 blind holes, the aperture 6mm of described blind hole, hole depth is 6-8mm.
Further, described metallization layer thickness is 8-25 μm, and described nickel dam I thickness is 2-6 μm.
Further, the described post that cuts down adopts ceramic sealing alloy 4J33 to make, and described nickel dam II thickness cutting down post excircle and bottom is 8-15 μm.
Pottery and metal material are compared with prior art effectively compounded to form ceramic shaft by the utility model, both the instructions for use of high-power microwave assembly had been met, turn improve pulse power and pulse voltage, also have that volume is little, lightweight, simple structure, assembly precision are high and the advantage of good insulating simultaneously.
