Definitions

  • the present invention relates to radio tubes, more particularly to the contact pin and base assembly for making connection between the elements of the tube and the external circuits.
  • an improved form of base in that the base is made of metal'and not only carries contact and locating pins but also constitutes the hermetic closure for the envelope.
  • all molded material, including the molded locating pin, is eliminated.
  • 'I'he contact pins are formed as continuations of the leading-in conductors, and the evacuating tubulation is so disposed as to serve as a combined terminal and' pin for locating the tube with respect to the socket.
  • FIG. 2 is a fragmentary plan view of the socket.
  • Fig. 3 is a perspective view of a clamp terminal which is employed to contact with the evacuating tubulation.
  • Figs. 4, 5,6 and 7 are sectional views, partly in elevation of several types of combined leading-in conductor and contact pin structures, while Figs. 8, 9 and 10 are sectional views of several types of combined evacuating tubulation and locating pin assemblies.
  • numeral I designates a cylinder consisting of any readily workable, inexpensive metal such as iron, nickel, etc. which is closed at the top (as shown) and terminates at the bottom in a flared rim 2.
  • a fiat metal plate 3 which will be referred to hereinafter as a base, since as will be explained, it serves all of the purposes of the usual bases.
  • the envelope l u contains one or more electrodes (not shown), in-
  • the leadingin conductor 4 is extended through the glass 6 and terminates in an enlarged portion 1 which is of a diameter sufficiently large to make good contact with openings in a metal socket member which will be described presently.
  • the enlarged portion l terminates at the end remote from the base 3 in a rounded blunt portion to facilitate the entry of the portion 1 into the socket opening.
  • the enarged portion l is conveniently fabricated as a separate member and then butt-welded to the conductor l, as shown in Fig. 4. l
  • Fig. 5 shows 4a modied form of Contact pin construction in which the leading-in conductor 4 is provided with a reduced diameter portion 9 immediately adjacent the pin.
  • the purpose of the portion 9 is to give flexibility to the combined pin and conductor so that any force applied laterally to the pin, as when the pin is being forced into a socket opening, will tend to bend the conductor at the constricted portion rather than at any portion which is contained Within the glass. Thus the seal is not deleteriously affected or strained under these conditions.
  • Fig. 6 shows still another modification of lead and pin construction in that the pin l is provided with a hole along its axis and the conductor 4 is extended to enter the hole and secured to the pin by soldering or welding. As in the case of Fig. 5, the conductor may be provided with a portion of restricted diameter if desired.
  • Fig. 7 shows another modified form of pin and conductor structure in that the conductor is provided with an enlarged portion l2 at the place where the conductor is sealed in the glass, so that the length of the conductor between the enlarged portion and the pin constitutes, in effect, a reduced diameter portion about which the entire structure will bend in case the pin is laterally strained.
  • the pin may be secured to the conductor by buttwelding or by means of an opening through which the conductor passes.
  • a hollow metal tubulation I3, anged at the upper end (as shown) is welded to the base member 3.
  • the lower end 33 of the tubulation is iiattened and welded tightly so as to form a hermetic seal.
  • a section of the Welded and flattened tubulation is shown in Fig. 8.
  • the metal tubulation including the iiattened end portion 33 serves not only as a terminal for making connection to the envelope but also as a pin for locating the tube and its base member with respect to the socket.
  • a composite structure of glass and metal may also be employed.
  • an eyelet I4 may be welded to the under side of the base member 3 about the evacuation opening.
  • a glass tip I5 is sealed to the lower edge of the eyelet so that after the tube interior has been evacuated, the tip may be fused to close the opening.
  • the metal eyelet I4 and glass tip I5 should preferably have the same coeiiicient of thermal expansion up to and including the softening temperature of the glass.
  • a cover or shield member I6 of metal may be welded or soldered to a iiange i'I which extends downwardly from the peripheral edge of the eyelet.
  • the member I6 can be employed as a terminal or a pin for locating the base with respect to the socket.
  • Fig. shows still another form of combined exhaust tubulation, terminal and locating pin but in this case the element is made entirely of metal.
  • the tubulation is provided at its upper edge with an outwardly extending flange which may be secured to the base member 3 at the exhaust opening.
  • a metal ball element i 9 may be employed for closing the end of the member I8 opposite to the base 3.
  • This ball has a diameter to correspond with the arcuate surfaces provided at the end of the tube I8.
  • the ball may be rolled into position in any suitable and well known manner after the tube has been evacuated and is rigidly held in place by solder or a weld. Suitable adaptors which will be described presently are provided on the socket to accommodate these various forms of tubulations.
  • 'I'he socket consists essentially of two heavy layers of varnished cambric which may be secured together and to a base plate or frame 2i of a radio set by a screw and nut arrangement 22. Openings 23 are provided in each layer of cambric andA positioned around a circle corresponding to' the position of the contact pins 'I on the base member 3. An opening 24 of larger diameter is also provided at a position corresponding to the position of the tubulation I3. There is a metal collar 25 about each opening 23 having a lengthwise slit 26 and held in position by an extension 21 which is secured in any suitable manner between the layers 2li.
  • the end of the strip 21 opposite from the collar 25 is extended outwardly and downwardly from the base as shown at 28 to constitute a terminal to which conductors can be secured.
  • the diametral size of the collar 25 is such as to grip the pin 'I tightly when the base member is inserted into the socket.
  • a structure such as that shown in Fig. 3 may be provided.
  • This structure takes the general form of a clamp 33 of spring steel having two legs 3l which are sprung open by a spacer member 32. 'Ihe distance between the legs 3
  • the legs II are restrained from opening too far by a metal U-shaped member 3
  • a transversely extending member is provided which has an opening for receiving a rivet 3G or a screw.
  • An extension 31 is provided on the clamp to facilitate connection with an external conductor.
  • contact pin and locating pin arrangement is such, particularly the manner in which these members are secured directly to the metal base 3, that there is no necessity for a base of insulating material such as is usually provided with tubes of this character.
  • the entire contact pin and locating pin assembly is carried solely by the base 3 which also serves the function of hermetically closing the open end of the. envelope I.
  • the improved pin and socket arrangement in connection with a metal tube, it will be understood that the improvement can be used successfully with tubes of the glass type, in which case the base 3 is made of a metal havingsubstantially the same coeiiicient of expansion as the glass envelope so as to be satisfactorily sealed thereto.
  • a base for an electric discharge device adapted to be mounted in a socket, said base comprising a metal disk adapted to be secured to said device, said disk carrying a leading-in conductor having a rigid end portion to serve as a contact pin, said disk also carrying a metal evacuating tubulation adapted to serve as a pin for locating the base with respect to said socket.

  • a base for an electric discharge device comprising a metal disk adapted to be secured to said device, said disk carrying a leading-in conductor having a rigid end portion to serve as a contact pin, said disk also carrying a metal evacuating tubulation adapted to serve as a contact pin, said'tubulation being of a size different from said pin, and a socket for receiving the contact pin and tubulation, said socket being provided with openings of sizes corresponding to the sizes of said pin and tubulation.
