Patented July 17, 1951 ELECTRODE AND RESISTOR ASSEMBLY UNIT Lester L. Stoffel, Lakewood, Ohio, assignor to The Ohio Carbon Company, Cleveland, Ohio, a corporation of Ohio Application September 2, 1948, Serial No. 47,381
1 Claim.
This invention relates to current limiting devices of the type employing a small gas filled lamp having a pair of spaced electrodes and conductors leading from the electrodes to the exterior of the lamp. A resistor is generally attached to one of the electrodes and in series with one of test leads to limit the current applied to the electrodes of the lamp.
My invention is concerned particularly with the connection from one of the electrodes of the lamp to the resistor. It has heretofore been customary to embed two conductors in opposite ends of a carbon resistor and to attach one of the conductors to a conductor leading from an electrode of the lamp. The connection is usually made by twisting together the lead from the resistor and the lead from the electrode, but the connection has not only involved an extra operation but has been unsatisfactory from the viewpoint of a lasting connection. To increase the efiiciency and certainty of the connection, as well as reduce the expense, my invention provides a single integral continuous conductor from the resistor to an electrode of the lamp. I accomplish this by embedding the free end of the electrode lead in the resistor so that no intermediate soldering or other means of joining is employed.
My invention is illustrated in the drawings hereof and is hereinafter more fully described.
In the drawings, Fig. 1 is an elevation of my electrode and resistor assembly; Fig. 2 is an enlarged view of the unit with the resistor in section; Fig. 3 is an elevation partly in section of a device embodying my electrode and resistor assembly.
In Figs. 1 and 2, l designates the electrode, II the resistor, I2 the conductor between the resistor and electrode and I3 the external conductor leading from the resistor. The conductor [2 is effectively secured at one end to the electrode I0 by bringing the end portion of the conductor alongside of the electrode and welding the two together where their ends overlap. The opposite end of the conductor I2 is embedded in the carbon resistor II. This end may be corrugated or distorted to insure an effective connection. The other resistor conductor 13 has its inner end also embedded in the carbon resistor, as shown in Fig. 2, and leads from the resistor to the line.
With such an assembly unit as above described solder at any portion is avoided and a more uniform and-certain connection is made.
Fig. 3 is an illustration of one embodiment of my assembly in a gas filled lamp testing device. This tester employs a gas filled lamp provided with the assembly unit described together with another electrode 20 and a conductor 21 connected thereto and extending to the exterior of the lamp. Two electrodes are mounted in a glass envelope 30, exhausted of air, and charged with gas in the usual manner. This glass envelope, as shown, may be surrounded by a protective transparent housing 31. The lamp conductors and the resistor are surrounded by an insulating protecting sleeve 32 carrying the housing 3|. The conductor [3 leading from the resistor and the conductor 2| leading from the electrode 20 are shown as provided externally with insulation l4 and 24, finally terminating in test prods l5 and 25 as is usual in this type of device.
My invention provides a combined electrode and resistor effectively coupled together and ready for the mounting of the electrode in the lamp. In the manufacture of the unit it is convenient first to weld the electrode to the conductor l2 and thereafter embed the other end of the conductor in the carbon resistor simultaneously with the embedding of the external conductor 13, to produce the unit shown in Figs. 1 and 2; however, if desired the welding of the electrode to the conductor l2 may be performed after the mounting of that conductor in the resistor.
I claim:
A lamp having in combination a gas filled globe with a pair of electrodes therein extending out of the globe, an insulating sleeve surrounding the projecting portions of said electrodes, a transparent housing covering said globe and connected at its free end to one end of said insulating sleeve, an elongated carbon resistor located completely within the sleeve and having a pair of conductors respectively embedded in its opposite ends, one of said conductors being welded at its free end to one of said electrodes, a connector wire welded to the free end of said other conductor and extending from the open end of said sleeve, another connector wire welded to said other electrode and extending from the free end of said sleeve and adapters connected to the free ends of the connectors extending from said insulating sleeve.
