Murray Fontaine Sklnker, Montclalr, N. 1., assignor to Federal Telephone and Radio Corporation, New York, N. Y.,
Delaware a corporation of Application March 22, 1945, Serial No. 584,138
I r y 01m (01.175-366) My invention relates to electrical rectifiers' oi the cartridge type which comprise a number of rectifier elements arranged in series.
More specifically, my invention is concerned with small unperforated selenium rectifier disks of the type shown m example, in United States Patent 2,359,377 to Miller et al. According to w my invention a number of. such disks are arranged in a metal container wherein they are subjected to pressure.
Another object of my invention is to provide a moisture-proof, self-contained rectifier. Other objects will be apparent from the follow- :ing detailed description taken in conjunction with the accompanying drawing, which shows diagrammatically and by way of example a preferred embodiment of the invention.
In this drawing,
Figure 1 is a view in perspective of -my rectifier unit;
. I 2 ii. In the same manner that the metal is crimped over the assembled parts the ends of the paper tube or jacket H are also crimped or bent over as shown at ll. For. the purpose of feeding the leads therethrough a hole 15 is provided in disk 4 and a hole- It in disk 5. From the approximate center oi the stack of rectifier elements an intermediate lead ll may be fed out through the paper lined metal jacket being Figure 2 is a vertical sectionalview of one form of rectifier unit embodying my invention:
Figure 3 is a sectional plan view thereof on the lines 3-3 of Figure 2.
Similar reference characters refer to similar parts of each of the several views.
The numeral I designates a selenium rectifier element or disk. A number ofthese are arranged in stack formation as clearly shown in Fig. 2 of the drawing. At one end of the stack, the bottom asshown in Fig. 2, a lead 2 is-connected to the end disk-as by suitable means as a drop of solder 3. This lead extends outside the rectifier element and passes through the center of an insulating disk 4. A portion of the lead inside the casing is flexible to prevent damage by endwise movement. Mounted next to, the disk 4 is a metal disk 5. The lead also extends through the metal disk and a drop of solder 6 is applied here also in order to hold the lead firmly in place and to form a moisture-proof connection. v
At the other end of the stack, the top as shown in Fig. 2, a coil spring 1 is mounted in such a manner as to pply the requisite amount of pressure to the stack. On the side of the coil spring 1 not adjoining the stack there is a metal disk 8 similar to the metal disk 5 and a lead 9 is attached thereto by means of solder ill.
The unit thus far described is encased iii a tube or jacket ii of insulating material such as paper which is used to prevent short-clrcuitlng. This paper tube. or jacket is in turn encased in a metal cover l2 whose ends are crimped over the ends of the assembled parts as shown at guided into electrical contact with the outer metal casing by means of an insulating bushing 18. This lead is soldered to a disk in the stack'by means of a drop 01' solder it.
The rectifier described above will, of course, provide full-wave rectification, the alternating current being fed to the leads 2 and 9 while direct current is derived from the lead ll, assuming the disks in the upper portion of the stack are reversed apart to those in the lower portion. The central lead 11, could of course be eliminated and the disks all stand in one direction if a halfwave rectifier is desired, while on the other hand the construction leads itself to the formation of a full-wave rectifier bridge by a proper disposition of the rectifier disks and additional intermediate leads, properly spaced, as will be apparent to those skilled in this art.
Additionally, while I have indicated a metal tube l2 provided with a separate insulating-jacket ll, preferably made of paper, it will be obvious that this insulating lining could be of any material, for example, molded inside the tube or could be formed as an insulating coating upon the inside of the metaltube. 1
Accordingly, while I have disclosed the prim ciple of my invention in connection with one specific embodiment and certain modifications thereof, it will be understood that these embodi- ,ments are given by way of example only and not as limiting the scope of the invention as set forth in-the objects and the appended claim.
an insulating disk intermediate said metal disk and one end of said stack, both of said disks having connecting openings through them, a first lead wire extending through said last open ings and connected to the one end of said stack,
a second metal disk adjacent the other end 01' said tube and having an opening therethrough, spring means intermediate said second metal disk and the other end or said stack, a second lead wire extending through said last opening and connected to the other end of said stack said first lead being attached to said first metal disc.
and said second lead being attached to said second metal disc, the ends of said metal tube being -crimped about the edges 01 the two metal disks to 101m a rectifier stack under spring pressure within said metal tube, insulating means intermediate sald metal tube on the one hand and said metal disks and said stack on the other hand, and a third lead extending through the opening in said metal tube and connected to adjacent oppositely connectedelements in said stack.
