Application-February 13. 193s, serial No. zV

` somma. (cina-339) My invention relates to sockets for vacuum In securing vacuum tube sockets to the mounting panel, it has been customary to rivet a '6 portion of the insulating base of the socket to l the panel. In this method, it often happenedi that the riveting operation would crush-or injure the insulating base part, thus rendering the entire socket useless.

Qne of the objects of my invention is to provide an improved mounting for a vacuum tube socken whicnwm obviate the nimcuny pointed out above.

.A further object of my invention is to provide a. securing member for holding the socket on the panel which 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 whichthe socket base may be mounted in various positions of Vrotaryadjustmentwith respect to the holder member.-

A further object of my invention is to provide an improved contact for engagingthe contact vpin on the tube which will give good velec- -trical contact and which will be inexpensive to manufacture and assemble. Further objects will be apparent from the specification and claims. .In the-drawing, in which my invention is shown.,

Figure I is a front view of a vacuum tube l socket construction embodying my invention;

Fig. 2 is a. section on the line 2-2 vof Fig. 1,

an embodiment of but showing the socket secured to a panel;

Fig. 3 isv a view of the socket with the outer insulating cover portion removed; f

Fig. 4 -is a perspective view of one of the contacts; Fig. 5 is a sectionon 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 showncomprises' 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 plurality of contacts 4 mounted thereon for engaging the contact pins on thevacuum tube, and means for holding the two parts of the base together and securing ,the base to the panel comprising a sheet metal ringzmember 5 surrounding the peripheral edges ot the base parts and havingllaterally extending wings or .ears B V through which the securing eyelets 3 extend,

.` sulating baseportions, as shown in Fig'. 3.

which secure the socket 'to the panel.` This ring member.may be oi' sheet metal and is provided with- 'an inwardly-extending annular ange 1 'against which an annular shoulder on the inner base part l rests. The outer base .part 9 is held securely in position in the ring by means ot a pair of ng'ers or Alugs I0 bent down into correspondingly shaped recesses Il in the rim of the outer base part 9. The outer base partis shown as provided with six of` these recesses so that the two 10 jpart base may be, secured in the ring in any one of six positions of rotary adjustment.v 'I 'his is of great convenience to the manuiacturenin that it enables himto bring the wiring terminals on the socket contacts into the desired position for wiring. v The Fuse of the sheet metal ears 6' for securing the so'cket to the panel avoids thenecessity 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 toeach'other by means of a flange portion I2 on the outer base part iltting over an annular shoulder of the inner base part. Y The base parts are positioned with respect to 2 eachother 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 il on the outer` base part which nts 'into a correspondingly shaped recess on the inner base part 8.. v y l As the contactfpins on-a vacuum tube are o! diierent diameters, it is necessary that the contacts on the socket and the openings inthe insulating base leading to these contacts should be correspondingly different' in size invorder to insure the proper engagement of the pins on the vacuum .tubes with the contacts on the socket.

With this in mind, thel contact 4, shown in perspective in Fig. 4, hasbeen designed. This con` tact is so designedthat the same blank may be used for making. the contacts both for the large diameter o f contact pins andior the smalldianieterl contact pins. VThe contact is made from a single blank ci 'sheet metal shaped to provide two sheet metalcontact members il and il between which the contact pin extendathese contact members i being trough-shaped in cross section-so that the'. .cut edges of the trough have yielding line con'- tactwith the contactpins. As'shown in Figs. 4, 5 50,

and 6,one of thesetrough-like contact members Il -is .wider than the other which insures proper positioning'of lthe contactwhen inserted into the correspondingly-shaped openings in the lower in- REISSUED v v base. In order to prevent the smaller troughlikev portion from shifting over toward the larger trough-like portion, a lug or finger I1 lis provided on the smaller trough-like portion which engages an annular shoulder on the outer insulating base portion, as shown in Fig. 2. The two trough-like portions are united at their lower ends by means 'of a portion I8 of the stamping, and soldering terminals are'provided as integral parts of the stamping, having openings I! through which 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 Il are bent inwardlytoward each other, 'more for the small diameter pin than for the large diameter pin, the cross-section ofthe 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 20 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 useV oi' this sheet metal cup-like member forholding the two' partsl of the plates together and `for securing the socket to the panel avoids the necessity for riveting 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 positionon 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.
