11 Claims. (c1. 173-339) My invention relates to sockets for vacuum,
tubes.
In securing vacuum tube sockets to the mounting panel, it has been customary to rivet a portion of the insulating base of the socket to the panel. Inthis method, it often happened that the riveting operation would crush or injure the insulating base part, thus rendering the entire socket useless.
One of the objects of my invention is to provide an improved mounting for a vacuum tube socket which will obviate the difliculty pointed out above.
A further object of my invention-is to provide a securing memberfor holding the socket on the panelwhich also serves to hold-the two parts of the socket base together.
A further object of my invention is to provide such a construction in which the socket base may be mounted in varlouspositions of rotary adjustment with respect to the holder member.
A further object of my invention is to provide an improved contact for engaging the contact. pin on the tube which will give good electrical eontact and which will be inexpensive to manufacture and assemble.
Further objects will be apparent from the speciflcation and claims. 7
In the drawing, in which an embodiment of my invention is shown,
Figure 1 is a front view of a vacuum tube socket construction embodying my invention;
Fig. 2 is a section on the line 2-2 of Fig. 1, but showing the socket secured to a panel;
Fig. 3 is a view of the socket with the outer insulating cover portion removed;
Fig. 4 is a perspective view of one of the contacts;
Fig. 5 is a section on the line 5--5'of Fig. 2;
Fig. 6 is a section on the line 6--6 of Fig. 2; and
Fig. 7 is a section on the line 1-1 of Fig. 1.
Referring to the drawing in detail, the construction shown comprises a panel I having an opening therein to receive a portion of the socket and a socket 2 secured in position on said panel by means of eyelets, rivets 3, or the like. The socket itself comprises a two-part insulating base, a pluralityof contacts 4 mounted thereon for engaging the contact pins on the vacuum tube, and.
means for holding the two parts of the base together and securing the base to the panel comprising a sheet metal ring member surrounding the peripheral edges of the base parts and having laterally extending wings or cars 6 through which the securing eyelets 3 extend, which secure the socket to the panel. This ring member may be of sheet metal and is provided with an in-" wardly-extending annular flange 1 against which an annular shoulder on the inner base part 8 rests. The outer base part 9 is heldsecurely in position in the ring by means of a pair of fingers or jugs is bent down into correspondingly shaped recesses II in the rim of the outer base part 9. The outer base part is shown as provided with six of these recesses so that the two-part base may be secured in the ring in "any one of six positions of rotary adjustment. This is of great convenience to the manufacturer, in that-it enables him to bring the wiring terminals on the socket contacts into the desired position for Wiring.
The use of the sheet metal ears 6 for securing the socket to the panel avoids the necessity for riveting through some insulating portion of the socket, thus eliminating this cause of breakage of the sockets. The two insulating base parts are centered with respect to each other by means of a flange portion I2 on the outer base part fitting over an annular shoulder of the inner base part. The base parts are positioned with respect to each other so that the openings on the outer base part will line up properly with respect to the openings on the inner base part by means of a lug or boss l3 on the outer base part which fits into a correspondingly shaped recess on the inner base part 8.
As the contact pins on a vacuum tube are of difierent diameters, it is necessary that the contacts on the socket and the openings in the insulating base leading to these contacts should be correspondingly different in size in order to insure the proper engagement of the pins on the vacuum tubes with the contacts on the socket. With this in mind, the contact 4, shown in perspective in Fig. 4, has been designed. This contact is so designed that the same blank may be used for making the contacts both for the large diameter of contact pins and for the small diameter contact pins. 'The contact is made from a single blank of sheet metal shaped to provide two sheet metal contact members l4 and [5 between which the contact pin extends, these contact members being trough-shaped in cross section so that the cut edges of the trough have yielding line contact with the contactpins. As shown in Figs. 4, 5 and 6, one of these trough-like contact members I4 is wider than the other which insures proper positioning of the contact when inserted into the correspondingly-shaped openings in the lower insulating base portions, as shown in Fig. 3.
As shown in Fig. 3, the larger trough portion fits in the larger portion of the opening in the insulating base, the cut edges of the larger trough-like portioneng'aging the shoulders IS on the openings in the base. This holds the larger trough-like portion in prop position on the base. In order to prevent the smaller troughlike portion from'shifting over toward the larger trough-like portion, a lug or finger I1 is provided on the smaller trough-like portion which engages necessity for riveting of a portion ill of terminals are provided as integral parts of the stamping, having openings l9 wires may be inserted for soldering. As stated above, the contact for engagement with the large diameter pin is made from the same blank as \the contact for the smaller diameter pin. The only difference in the complete contacts is that the sides of the larger trough-like contact member H are bent inwardly toward each other, more for the small diameter pin than for the large diameter pin, the cross-section of the contact for the small diameter pin being shown in Fig. 6 and the cross-section for the large diameter pin being shown in Fig. 5.
It will be seen that the use of the ring member 5 for holding the two parts of the insulating base together avoids the necessity for a central securing member, thus leaving the outer central portion 2|! of the outer insulating base portion clear and unobstructed so that an identifying member or character may be molded on this central portion. It will also be seen that the use of ths sheet metal cup-like member for holding the two parts of the plates together and for securing the socket to the panel avoids the through an insulating. part, thus eliminating this source of breakage. It will be seen that the contacts are so designed that they afford a desirable engagement with the contact pins on the tube by means of the four cut edges, that the contacts for the different sizes of pin may be made from the same blank and that means are provided for holding the contacts firmly in desired position on the insulating base.
Further modifications will be apparent to those skilled in the art and it is desired, therefore, that the invention be limited only by the prior art and the scope of the appended claims.
