TUBE SOCKET Filed March 1 1951 INVEN T012.
MILTON R. BRUSH United States Patent TUBE SOCKET Milton R. Brush, Rochester, N. Y., assignor to the United States of America as represented by the Secretary of the Army Application March 1, 1951, Serial No. 213,411
8 Claims. (Cl. 339-64) This invention relates to improvements in tube sockets, and more particularly to a specific construction therefor to meet the special requirements of the so-called Litton tubes.
In the various forms of tube sockets heretofore used for magnetrons of the plural-cavity type, an example of which is shown and described in Patent No. 2,474,263 issued June 28, 1949, to Charles V. Litton, there has sometimes occurred loss of adequate contact pressure between the flexible, spring-contact fingers of the socket and the spaced and concentrically disposed terminal rings or cylindrical connector elements making up that end or male part of the tube which is plugged into the socket. It has been the practice heretofore in a socket of this type to rely entirely upon the flexibility or spring action of the contact fingers to obtain electrical, spring-contact with misaligned connector elements of the tube. To compensate for extreme eccentricities, however, these fingers must be so flexible that assurance of adequate contactpressure is lost, especially in regard to fingers on the half circumference left behind by any off-center connector element or terminal ring of the tube.
With the foregoing in mind, it is one of the objects of this invention to provide an improved socket for a Litton tube or other device wherein there is the problem of misalignment of connector elements or terminal rings, the socket structure to be eflective to compensate for such misalignment and simultaneously to provide adequate contact pressure on each of any misaligned connector elements or terminal rings.
Other objects and advantages will hereinafter appear.
For the purpose of illustrating the invention, an embodiment thereof is shown in the drawing, wherein Figure 1 is an elevational view of a tube socket having structural and operating characteristics in accordance with the present invention;
Figure 2 is a plan View of Figure 1;
Figure 3 is an enlarged, sectional view, the section being taken on the line 33 in Figure 2; and
Figure 4 is a fragmentary, perspective view of the end or male part of a Litton tube for which a tube socket embodying the present invention is particularly adapted.
As shown more clearly in Figure 3, a tube socket to have the desired structural and operating characteristics aforesaid, may consist of the three tubular, metal elements 10, 11 and 12 of varying diameters and length. These elements are supported in spaced, concentric relation with respect to each other to receive, respectively, the connector elements or terminal rings a, 11a and 12a of a Litton tube. The latter correspond to and are the equivalent of those designated, in the Litton patent aforesaidl, by the reference numerals 52, 49 and 48, respective y.
To provide for a compensating bodily or tilting movement of each of the elements 10, 11 and 12 independently of and with respect to each of the other two, discs 14 of sponge rubber or other equivalent flexible and dielectric material, are employed and disposed as shown in Figure 3, one on each side of the respective base flanges 10b, 11b and 12b of these elements.
At the upper ends of elements 10, 11 and 12, the gauge or thickness of the metal is made less than that of the more rigid body portion of these elements, as clearly shown in Figure 3, to give the desired flexibility or spring to the respective, cylindrical sets of contact fingers 10c, 11c and 12c which are made by slotting these upper ends. Slots 10d, 11d and 12d are also made in the respective elements 10, 11 and 12 to provide for more etficient cooling of the vacuum tube.
V The base flanges 10b, 11b and 12b which interleave with the sponge-rubber discs 14, may be soldered or otherwise made an integral part of the associated elements 10, 11 and 12, and are provided, respectively, with the lugs 10e, 112 and 122 to which circuit connections can be made.
The base of the improved tube socket consists of a cup-shape part 15 and a cover part or plate 16, both parts being of Bakelite or other dielectric material and secured together by studs 17. A slot 15a in base part 15 accommodates the lug 102. This slot may be cut deeper than is shown in order to clear lug 102 and thus allow for a slight clockwise movement, as viewed in Figure 3, of element 10 and its flange 10b, with respect to the base part 15.
The vertical dimension at 16a is such that when studs 17 are screwed home into base part 15, the discs 14 of sponge rubber are compressed, but not fully, between parts 15 and 16. This allows for further compression of discs 14 incident to occurring bodily movement of any of the elements 10, 11 and 12 either axially, or laterally out of alignment with the vertical axis common to all. As shown in Figure 3, the circular discs 14 have a snug fit within the cup-shape base part 15, and also have a similar fit about the cylindrical elements 10, 11 and 12. In assembly of these parts, therefore, the flexible discs 14 center elements 10, 11 and 12 on the common vertical axis and yieldingly hold them in alignment. The outside diameter of the circular flanges 10b, 11b and 12b is substantially less than that of discs 14 so that the former are entirely clear of and are therefore free to tilt in any direction with respect to part 15.
In operation, when a vacuum tube or other device having a male portion or plug as shown in Figure 4 is inserted into the socket, the discs 14 first give slightly under the downward pressure exerted, but then furnish a practically rigid backing, in the vertical or axial direction, for elements 10, 11 and 12 and their associated flanges. As this action occurs, however, and should there be any misalignment between any of the vacuumtube contact elements 10a, 11a and 12a and the respective sets of spring contacts 100, 11c and 120, the spongerubber discs 14 will yield accordingly to permit adequate shifting of the base flanges 10b, 11b and 12b and accompanying bodily movement of elements 10, 11 and 12 into alignment with the respective axes of the misaligned rings or contacts 10a, 11a and 12a. Since each of the three sets of spring contacts or fingers 10c, 11c and 126 is thus enabled to move bodily to align itself with the respective, complementary vacuum-tube contact element, each finger is able to contribute its share of the currentcarrying function. Also, as the individual fingers of any set need flex only enough to allow the respective contact element to slide into position, material of greater than ordinary rigidity may be used for the fingers, and a proportionate increase incontact-pressure obtained.
From the foregoing it will be seen that in the improved construction for a tube socket, there is compensation or allowance for any misalignment of the cylindrical connectors or terminal rings of a vacuum tube such as the Litton tube aforesaid. For this purpose, and in accordance with the broader aspect of the present invention, the cylindrical sets of flexible fingers or spring contacts are individually supported by flexible pieces of insulating material whereby they are free to move bodily, out of alignment with the other sets, and sufliciently to compensate for any misalignment of the cylindrical connectors or terminal rings of the tube.
While but one embodiment of this invention has been shown and described, it will be understood that various modifications such as in the size, shape and arrangement of the parts are contemplated, and that such modifications are considered to be within the conception of those skilled in the art and within the spirit of the invention and the scope of the claims.
