Definitions

  • This invention relates to leading in devices for metallic vacuum-discharge containers of the kind wherein the metal parts that are situated in vacua, and influence the electric field in the neighbourhood of the insulatorV of leading-in device of the kind described' wherein the said metal parts are held in their position in an improved manner.
  • a leading-in device of the kind described for a metallic vacuum-discharge container, wherein the metallic parts that are situated in vacua, and influence the electric field in the neighbourhood of the insulator sealing the vacuum, are held fast in their position 'at .30 least in part by soldering, brazing, or welding, for example spot-welding, or like securing means.
  • the metal partsv influencing the eld will, at least in part, be fixed rigidlyrelatively to the two metal tubes adjoining the vacuumsealing insulator.
  • these two tubes in general, are not positioned ⁇ suflicientlyexactly ,coaxially relatively to one another, .aocording to another feature of the invention the metal parts are ⁇ at 'least' in part arranged coaxial to anaxis that is cent-ra relatively tothe two ymetal tubes.
  • the device may be constructed as follows
  • the parts to be assembled together'with the glass-metal assembly, such as the electrode-neckor conductor, the protective cylinders which, according to the specification N.O. 170,505V almost cover over the faces of the insulator towards the vacuum, as well asfother parts, protective tubes, caps andthe like, which exert an influence on the field-disl tribution inthe neighbourhood of the insula* tor, are clamped by asuitable mount coaxially tota centralaxis of the glass-metal assembly and then held in this position by Welding or soldering k
  • the line connecting the centers of twospheres which can be described in the two metaltubes near their fused edges may be taken, for example, as the middlelongitudinal axis of the glass-metal assembly.
  • the welding or soldering can be done electrically. with the arc or asspot-welding or with a lflame.
  • B1 and B2 are metal cylinders which establish the desired potential distribution at the inner surface of the glass insulator G.
  • the cylinders B1 and B2 are centered relatively to the ytubes, R1 and R2 by annular bosses U of triangular section.- They Y are held rigidly in their yposition by lugs D whichare welded both tothe tubes R1, R2 i 4 and to the cylinders B1, B2.
