Abstract
The utility model discloses a miniaturized three-stage depressed collector for a multi-beam traveling wave tube. The miniaturized three-stage depressed collector comprises a first collector and a second collector; a first insulating ceramic cylinder and a second insulating ceramic cylinder as well as a first kovar alloy cylinder and a second kovar alloy cylinder are sheathed outside the first and the second collectors in sequence; the top of the second kovar alloy cylinder is provided with a metal flange plate, wherein the metal flange plate is internally provided with three pins; a third collector is also arranged in the second collector; and wires are respectively led out from the first, the second and the third collectors to penetrate out through the pins. For the miniaturized three-stage depressed collector, the weight and the volume of the collector are greatly reduced, the parts are reduced, and the assembling and manufacturing process is simplified.
Description
Technical field
The utility model relates to travelling wave tube depressed collector field, and especially the multi-traveling wave tube depressed collector is specially a kind of multi-traveling wave tube miniaturized three grades of depressed collectors.
Background technology
The depressed collector of travelling wave tube can be converted into the energy storage in the power supply with the dump energy of electronics after the radio-frequency field mutual effect, reduces the heat dissipation of collector, improves the efficient of homogeneous tube.
Multi-traveling wave tube is a kind of volume single big pipe kind of tube power of annotating little, in light weight, that depress than same electrical.These characteristics show that multi-traveling wave tube is specially adapted to volume, weight are had the system of specific (special) requirements, for example missile borne system etc.For the better advantage of performance multi-traveling wave tube, be that complete machine is saved more space and weight, the collector of multi-traveling wave tube requires to accomplish that volume is little, reliable in structure, electrical property are good.
The utility model content
The purpose of this utility model provides a kind of multi-traveling wave tube miniaturized three grades of depressed collectors, can realize three grades of depressed collector miniaturizations structurally of multi-traveling wave tube, to solve the travelling wave tube collecting pole structure complexity in the conventional art, the problem that volume weight is big.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Multi-traveling wave tube miniaturized three grades of depressed collectors, include first collector of tubular, it is characterized in that: described first collector is set with the first insulating ceramics tube outward successively, the first kovar alloy tube, be provided with second collector of tubular in described first collector, first collector is stretched out on the described second collector top, and the second collector extension is set with the second insulating ceramics tube outward successively, the second kovar alloy tube, the described second alloy tube and the first kovar alloy tube are spliced into one up and down, be positioned at the second alloy tube top and be covered with the metal flange dish, three pins are installed in the described metal flange dish, second collector that is arranged in metal flange dish below also is provided with the 3rd collector, described the 3rd collector connects as one by potsherd and described metal flange dish, from described first collector, there is lead to draw respectively on second collector and the 3rd collector, describedly draws that lead is corresponding one by one draws by the pin in the metal flange dish.
Described multi-traveling wave tube miniaturized three grades of depressed collectors is characterized in that: described pin bottom is equipped with to be enclosed within draws the outer welding ring of lead.
Described multi-traveling wave tube miniaturized three grades of depressed collectors is characterized in that: the lead of drawing of described first collector is with earthenware outward.
The utility model comprises first collector, second collector and the 3rd collector, first collector, second collector is set with the insulating ceramics tube of tubular outward, the outer suit metal cylinder of insulating ceramics tube, the 3rd collector connects potsherd, potsherd connects the metal flange dish, the metal flange dish is embedded in the pin of three ceramic cup-shapeds, from first collector, draw three on second collector and the 3rd collector respectively and draw lead and pass pin, the pin bottom connects the welding ring of the metal of disk shape, and first collector is drawn lead and put earthenware outward.First collector, second collector and each self-corresponding insulating ceramics tube directly are welded to connect, and bonding area calculates minimum value to reduce volume as far as possible according to the heat transfer demand.The metal flange dish is directly selected expansion alloy for use, can adopt kovar alloy, selects the direct and pin welding of the suitable margin of tolerance.Draw lead and directly pass pin, and connect by pin soldering and sealing and to draw outside the collector.
The utility model has dwindled the weight and volume of collector greatly, has reduced parts, has simplified the assembling manufacturing process.Compare with traditional collector, weight has reduced 70%, and diameter has reduced 25%, has highly reduced 15%, and the while is withstand voltage can to reach 12KV, and electric property is good, satisfies the demand of multi-traveling wave tube.
