Definitions

  • This invention relates to the means by which an electron tube and its socket are interconnected, and is more particularly concerned with short-wave tubes of the kind having their bulb made of pressed glass.
  • One feature of the invention is that the bottom of such glass bulb is used as a stop for the socket, the accuracy, in the manufacture of pressed glass bulbs being such that the tolerances concerned are not greater than $0.1 millimeter, as has been proved by numerous tests.
  • FIG. 1 is a partially diagrammatic sectional View illustrating one embodiment of the invention
  • Fig. 2 shows a section on line 2-2
  • Fig. 1 shows a section on line 2-2
  • Fig. 3 is a sectional view representing a slight modification of the socket shown in Figs. 1 and 2.
  • I denotes the socket while 2 indicates the electron tube whose bulb is made of pressed glass.
  • the bottom A of the bulb has a re-entrant fiat part in which the lead-in conductors 3 are mounted. These conductors are to engage with contact springs which form part of the socket. For simplicity these springs are not illustrated.
  • Bottom A is shaped to grip over a central annular projection or upturned edge B of the socket l and thus serves as a stop intended to come against the edge B as counter-stop.
  • Bottom A is formed with lugs C for notches D provided in the edge 13.
  • the lugs enter the angular position with respect to each other, that is, the position necessary for the conductors 3 engaging with the proper contact springs of the socket.
  • the parts A, B thus constitute a sort of coarse guide, while C, D constitute the fine guide.
  • the socket shown in Fig. 3 has a circumferential projection or upturned edge E that serves as an additional guide for the electron tube.
  • An electric discharge device comprising an electron tube and a socket therefor, this tube having a bottom arranged to act as a stop adapted to come against a stop forming part of the socket, the stop of the socket being a central annular projection thereof while the said bottom is shaped to grip over this projection.
  • a discharge device wherein the stop of the socket is a central annular projection thereof and which comprises guide means to insure a determinate angular position of the electron tube with respect to the socket.
  • a discharge device according to claim 1, wherein the stop of the socket is a central annular projection thereof and which comprises notches and lugs of such projectionand said bottom to insure a determinate angular position of electron tube and socket.
  • a discharge device according to claim 1, wherein the socket has a circumferential projection as an additional guide for the electron tube.
