Description

March LGPP Q ELECTRIC DISCHARGE DEVICE;
Filed Feb. 4, 1941 MVmll/Illl lhvehzbr: 6097211261 30);
Patented Mar. 24, 1942 ELECTRIC DISCHARGE DEVICE Edmund Liipp, Berlin, Germany, assignor to C. Lorenz Aktiengesellschaft, Berlin-Tempelhof, Germany, a company Application February 4, 1941, Serial No. 377,311 In Germany January 20, 1940 4 Claims.
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.
In the drawing, 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, while 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.
What is claimed is:
1. 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.
2. A discharge device according to claim 1, 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.
3. 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.
4. A discharge device according to claim 1, wherein the socket has a circumferential projection as an additional guide for the electron tube.
