Description
The present invention relates to vacuum tube, relate in particular to an end bearing at end plate and around two electrodes and the supporting structure of the cantilever shield that sets.
Fig. 7 represents for example cutaway view of the existing vacuum tube structure shown in 1978 No. 32870 communique of Japanese patent laid-open publication gazette.In the drawings, the 1st, constitute by the contour insulating component of aluminium oxide ceramics and to be insulating vessel cylindraceous, 2, the 3rd, with scolders such as silver solders for example by the end plate of soldering at described insulating vessel 1 two ends, and be formed with patchhole 2a, 3a at central portion respectively, the 4th, connect to insert end plate 2 patchhole 2a, with the fixed electrode rod of end plate 2 airtight joints.
The 5th, connect to insert the patchhole 3a of end plate 3, by bellows 6 and with the movable electrode rod of end plate 3 airtight joints, 7, the 8th, subtend and fixing pair of electrodes respectively on the top of fixed electrode rod 4 and movable electrode rod 5,9 is cantilever shields that an end bearing sets around two electrodes 7,8 on end plate 3 and with other end gusset.And constitute airtight container 10 with described insulating vessel 1, two end plates 2,3 and bellows 6.
Below, describe with regard to the manufacture method of the existing vacuum tube of above-mentioned formation.
At first, carry out the part of conduct assembling and assemble, reach the movable side part assembly parts of forming by end plate 3, movable electrode rod 5 and electrode 8 with the fixation side part assembly parts that electrode 7 is formed, in nonoxidizing atmosphere, assemble by soldering by end plate 2, fixed electrode rod 4.Therefore, when part soldering assembling finishes, then for example solder fusing deficiency, scolder are not stained with and scolder spreads deficiency etc. and carries out visual inspection totally, to improve reliability.
Then, on the end plate 3 of movable side part assembly parts, one end of cantilever shield 9 is fixed by soldering, and, the finally sealed assembling of vacuum tube is, between the both ends of the surface of the end plate 3 of the end plate 2 of fixation side part assembly parts and movable side part assembly parts and insulating vessel 1, accompany scolder, high temperature with 400 ℃～600 ℃ in vacuum furnace cures, after carrying out sufficient degasification, be warmed up to brazing temperature and carry out airtight sealing with melting solder, and carry out the inspection of last airtight soldering portion, thereby made vacuum tube.
Because of existing vacuum tube such as above-mentioned structure, manufacturing, except necessary visual inspection soldering position, the soldering operation of subassembly preface, cantilever shield and 3 soldering operations of finally sealed assembly process also must be arranged, so exist the more manufacturing cost of cost and the problem in man-hour.In addition, if do not carry out the soldering operation of cantilever shield, when the cantilever of soldering simultaneously shield 9 in the subassembly preface, then because soldering position that can not visual inspection cantilever shield 9 inboards, so produced the necessity of carrying out air test, when this air test is also taken a lot of work, again owing to can not fully confirming the mobility status of scolder, so exist the problem that reliability reduces.
For eliminating above-mentioned problem, the objective of the invention is to: a kind of vacuum tube is provided, with the brazing state of cantilever shield make can be visual structure, and by in the end can carrying out the soldering of cantilever shield in the assembly process, thereby can obtain the vacuum tube that manufacturing cost reduces, shorten man-hour and reliability improves.
The vacuum tube of claim 1 of the present invention in the described vacuum tube, has: insulating vessel cylindraceous; Seal a pair of end plate at described insulating vessel two ends; Be seated in the pair of electrodes that to leave, dock in the airtight container that forms with insulating vessel and two end plates; For setting around described two electrodes and end cantilever shield of soldered joint on any one end plate in two end plates; Wherein, the structure at the junction surface of end plate and cantilever shield is, fusing and the portion of spilling that spills scolder is exposed at the outside of airtight container
The vacuum tube of claim 2 of the present invention, according to claim 1, to the end plate at junction surface a, end of cantilever shield is outwardly-bent and form to have than the little outside sweep edge of end plate diameter and the other end with and containment member that an end with insulating vessel engaged littler than this outside sweep edge diameter and curve inwardly and the interior curved edge that forms carries out superimposed successively, and described end plate, outside sweep edge and interior curved edge engage by the fusing that is configured in the scolder between each superposed surfaces.
The vacuum tube of claim 3 of the present invention, according to claim 1, end plate to the junction surface, thereby with an end of cantilever shield outwardly-bent and having of forming of peripheral part at peripheral part for and 1st sticking part that downwards be bent to form chimeric and and 2nd sticking part that form outwards outstanding superimposed outside sweep edge on end plate from the 1st sticking part lower end with the end plate periphery, and an end engages with insulating vessel and another distolateral and the 1st sticking part containment member that the other end is fitted in the 2nd sticking part chimeric the time carries out chimeric successively, and between the superposed surfaces at described end plate and outside sweep edge and between the chimeric surface of described the 1st sticking part and containment member, the fusing by the scolder that is configured engages.
The vacuum tube of claim 4 of the present invention, according to claim 1, with the end difference that forms along periphery in end sheet surface at junction surface with form bigger and outstanding upward and outside sweep edge that have a sealing that engages with insulating vessel carries out superimposed outwardly-bently at peripheral end than end plate diameter with chimeric cantilever shield one end of this end difference inner peripheral surface, and between the superposed surfaces at end difference and outside sweep edge, the fusing by the scolder that is configured engages.
The vacuum tube of claim 5 of the present invention, according to claim 1, by forming the end plate in prescribed level hole in the outer edge and making the outwardly-bent outside sweep edge that forms of cantilever shield one end carry out superimposed with the junction surface, with plugging hole, and between the superposed surfaces at described end plate and outside sweep edge, the fusing by the scolder that is configured engages.
The vacuum tube of claim 6 of the present invention, according to claim 1, with another of the containment member that at one end engages with insulating vessel distolateral go up with end plate and outside sweep edge periphery can be chimeric and end difference that form supports the end plate at junction surface and make cantilever shield one end outwardly-bent and form and end plate same outer diameter as and the outside sweep edge superimposed with end plate, and between the superposed surfaces at end plate and outside sweep edge, the fusing by the scolder that is configured engages.
