2O
3Potsherd, described through hole has four, and circumference is evenly distributed on the potsherd.
Described a kind of be used for space travelling wave tube level Four depressed collector go out to hold assembly, it is characterized in that: the edge of described potsherd and in edge 1mm place, the potsherd through hole inwall and metallize respectively apart from inwall 1mm place, the upper surface of potsherd is except metallized part glazing.
Described a kind of be used for space travelling wave tube level Four depressed collector go out to hold assembly, it is characterized in that: described collector goes out to hold sleeve and the nickel plating respectively of output connection sleeve surface.
The utility model utilizes the 95Al2O3 potsherd of a thickness for 2mm, and replacement can be cut down end cap, potsherd is welded to collector goes out to hold on the sleeve, and four of circumference uniform distribution holes are used for welding the output connection sleeve on the potsherd, to replace four sealing-in insulators.
The beneficial effects of the utility model are:
1, the whole height that goes out to hold assembly only is 7.7mm, thereby has reduced the length of whole assembly greatly.External diameter Φ 1.3mm in the whole assembly, the very light in weight of the output connection sleeve of long 7.4mm has alleviated the whole weight that goes out to hold assembly on the whole;
2, assembly technology is simple, and each solder wire and solder sheet are put into assembling point back respectively only to be needed just can finish the whole encapsulation that goes out to hold assembly by welding once;
3, each pad place, on have under the solder wire solder sheet arranged, make the vacuum-tightness that goes out to hold assembly after the welding obtain dual assurance, improved the reliability that to hold assembly greatly;
4, potsherd outer surface glazing can guarantee the cleanliness factor of ceramic outer surface by alcohol wipe, thereby has improved the voltage endurance capability on potsherd surface.
