Definitions

  • Thermionic tubes have been disclosed in the prior art in which .the electrode supply leads are brought through-what is known as a squash at one end of the vacuous vessel.
  • Thermionic tubes of this kind offer the advantage that they are easily manufactured.
  • the present invention discloses a method of providing tubes of this sort with sockets or holders.
  • the mechanical securing of tubes upon the holder is insured by the aid of traction of the tubes against the holder produced by wires enclosed within the squash without cementing.
  • These fused-in or sealed-in wires whereby the tubes are pulled against the base of the socket may be provided separately (dummy wires) or else may constitute the current-supply leads for the tubes. Since the wires confined in the squash are mostly lying in one plane, it is suitable to dispose the squash planar on the surface where it comes to lie against the tube holder, or, if desired, to provide it with a flange as shown in Figs. 1 and 2.
  • S denotes the plus
  • I denotes insulating material in which the said pins are secured and supported.
  • a guide bar F or the like on the tube holder adapted to prevent tilting of the tube in relation to the holder.
  • the construction of such guiding element turns out to be particularly simple if the tubular pins provided on the tube holder, and with which the sealedin wires are united by soldering, clamping, or the like resulting in a condition of tension, are split at the end turned towards the squash so that they result in claws (Fig. 3.). These claws may be bent around a flange provided on the squash and serve for aflordin mech anical supporting for the tube.
  • uch tube holders which are especially well suited for the supporting of externally controlled tubes having an oval or flat cross-sectional shape are most suitably made dissymmetric in such a way that the proper introduction of the holders into the corresponding sockets will be assured from the outset.
  • a suplementary pin may be provided, said in eing disposed dissymmetrically with re erence to the others, and serving, forinstance, for the connection of the control electrode;
  • An electrical discharge tube compris-f ing a tubular glass envelope enclosing electrodes and having at one end an outwardly projecting press, a base comprising an insulating member shaped to fit snugly against the end of said press and provided with contact pins, and leading-in wires sealed into and extending thru said press with their inner ends connected to said electrodes, and their outer ends to said contact pins to place the outer portions of said wires under sufficient tension to hold said base in place on said press.
