Referring to fig. 1-6, an end cap structure for a solder-integrated magnetron molybdenum strut assembly comprises an upper end cap 2 having a connecting part 1 at one end, wherein the connecting part 1 is preferably a cylinder protruding downwards, so that a filament 3 can be conveniently sleeved, and the connecting part is more attached; the welding device further comprises an upper molybdenum support rod 6 which penetrates through the through hole 5 of the lower end cap 4 and is welded at the lower end of the connecting part 1 in a non-contact manner, and a lower molybdenum support rod 7 which is welded at the bottom of the lower end cap 4, wherein an annular slot 8 is formed in the upper end of the bottom of the lower end cap 4 at the periphery of the through hole 5, a filament 3, preferably a thorium tungsten filament, is sleeved on the upper molybdenum support rod 6 in a non-contact manner, and is the earliest used rare earth tungsten electrode which has good welding performance; one end of the filament is sleeved and fixed on the connecting part 1, the other end of the filament is inserted and fixed in the annular slot 8, and the annular slot 8 is provided with a coating part for coating solder, so that the filament 3 can be prevented or reduced from deflecting in the process of sintering the solder.
Referring to fig. 3 and 4 again, specifically, the coating portion may be an annular groove 9 disposed at the upper end of the annular slot 8, and the annular design facilitates coating solder at any angle and is convenient to use; further, the diameter of the annular groove 9 is larger than that of the annular slot 8 and is concentrically arranged with the annular slot 8, and the concentric arrangement can keep the distance between the inner wall of the annular groove 9 and the filament 3 consistent, so that the filament 3 is better prevented from deflecting. After annular groove 9 is added, the solder coating is in annular groove 9, no longer coats the solder in original annular slot 8, and annular slot 8 can not change easily with filament 3's contact site and angle for filament 3 can not produce the skew off-centre at the location in-process, climbs to filament 3 upper portion fixed filament 3 through the capillary action through the high frequency heating solder simultaneously, realizes the quick alloying of solder through high frequency heating, firm in connection.
Referring to fig. 5 and 6 again, in particular, the coating portion may also be at least one slot 10, preferably two slots, which are disposed opposite to each other, on the inner wall of the annular slot 8, or may be distributed uniformly in multiple slots, so as to maintain a symmetrical pair of positions of the applied solder, and better prevent the filament 3 from deflecting; one side of the slot 10 is communicated with the annular slot 8, so that solder can be fully contacted with the filament 3, the top of the slot 10 extends to the top of the lower end cap 4 and forms a solder inlet, the solder is conveniently placed, and in addition, the slot 10 can be in a fan shape, an ear shape, an isosceles trapezoid shape and other suitable shapes.
