The: presentlinvention relates to sockets for vacuum tubes, connector plugs and the like and more particularly to sockets adapted for holding extremely small vacuum tubes.
Within recent years, the art of making elecconnectorv plugs, and the like having means intronic devices using extremely small circuit comtegral with the socket terminal members for ponents has been developed, so that it is now spacing-the socket from the mounting panel. possible to construct. such devices using a numstillanother object of myinvention is to prober of vacuum tubesxof a size that such an elecvidei'an improved socket installation for use with tronic device may be placed in a vest pocket or 10 vacuum tubes, connector plugs, and the like in the fuse nose of a'shell or bomb.

A still further object of my invention is to provide/an improved socket .for vacuum tubes,

Fig. 17 shows a cross-sectional view taken on line i'i-ll of Fig. 14 showing the tube prong in the contact bore and the contact.-
In the preferred embodiment of my invention shown in the drawing, the socket l of my invention is shown mounted on a panel 2. This panel or base 2 may be of ceramic or other insulating materials and may be the panel on which the circuit componentssuch as conductors, induct ances, resistors, and. condensers, are mounted in assembling an electronic circuit device by methods known by those skilled in the art. In the more compact devices certain of these components may be printed, painted, adhesively secured or other wise mounted on the panel. In the drawingthereis shown only the electronic circuit conductorelements 3 which connect to the socket I". These elements may be strips of foil, adhesively secured to the panel or conducting'strips of metal or other material adhesively or otherwise mounted to the panel 2.
In the panel or base 2 are shown five apertures d disposed in two substantially parallel lines for mounting the socket I. The conducting elements 3 are shown mounted on the panel extendingfromand adjacent the apertures 4. One' element is shown on one face of the panel 2' leading: away from one aperture and five are shown on the reverse side, one leading away from each aperture.
The socket l of my invention comprises a socket body 5 of insulating materi'alin which are mount"- ed the contact prongs 6. The socketbody 2 in the" embodiment shown is a substantially rectangular block having five substantially parallel rectangu= lar cross-sectional contact-receiving. bores T extending from one end 8 of the block to the opposite end 9. The number of apertures. however, may be varied to suit. the requirements of the vacuum tube used in the circuit. In these-opposite end faces 8 and 9 of the block are disposed grooves 58 extending substantially parallel toeach other from the ends of the contact-receiving bores 1" and to one face or base l2- of the block 5' and providing ridges ll between the grooves I90.
The contacts 6 for the socket are'made from strips. of conducting material having, a width approximately equal to the width. ofthe contact receiving bore I of the socket. Eachcontact ele ment 6 has an arcuate resilient portion 13 which is disposed in a contact-receiving bore 1 or the.-
i9 adjacent the end. At the other end of the arcuate portion l3 there may be disposed an? angular offset I5 providing a portion ofthe-strip for bearing against the side of the bore 1 adjacent the base. Also, at this other end there is disposed a terminal portion l 6 extending along meg-move 50 adjacent that end and beyond the base' li of" the-socket body. Both the hook portion I4" and the terminal portion 16 are parallelly disposed to each other and extend substantially-ncrmalto an imaginary line connecting the ends" of the resilient arcuate portion 131 On the terminal portion [6 are disposed wing portions l-Textending from opposite side edgesthereof'spaced fromthe arcuate portion [3 by an amount substantially equal to the distance from-the 'contaet-receiying 4 bore Tin the socket along the groove to the base 12 of the socket body.
The resilient arcuate portion 13 is disposed in the contact-receiving bore with the hook portion I4 and the terminal portion 18 engaging the grooves l9 between the ridges I l with the terminal portion extending beyond the socket body with the terminal wings I! disposed adjacent the surface of the body. The ridges [I provide means for insulating and separating portions of adjacent contact prongs 6. In the embodiment shown the terminal portions l6 of the contacts 6 are shown disposed at alternate ends of adjacent bores 1. However, such symmetrical displacement is not necessary and the disposition of the terminal ends can be varied in accordance with the technical requirements of the device which the socket is mounted.
The socket I is secured to the base 2 by inserting the terminal portions I6 through the apertures 4 of the base Zuntil the wings I! rest upon-the base 2 thereby spacing the socket I from the base 2. The ends is of the terminal portions may then be" foldedior otherwise bent securely against the base 2 or any'conducting. element 3'on the surface of the base 2 adjacent to the aperture 4 through which the particular end 18- extends. These terminal ends l8 maybe soldered 'to the circuitconducting elements in order to improve connection therewith. The wing. elements I! are caused to be in mechanical contact with the sur-' face of the base and may" be. soldered to any conducting element on that face of the base 2 and disposed adjacent thereto.
Generally the'socketof my invention-is particularly adapted for use with subminiature vacuum tubes 19 015 the type shown in Fig. 16 which" is a greatly enlarged view. These tubes l9 are generallyabout-aninch to an inch and aquarter in length and have their terminal prongs 20' disposed substantially in a plane extending from one end of the'tube. The prongs 20 of the tube l9 may be inserted in' accordance with the circuit and design requirements of the particular device through either end' 8 or. 9 of the socket! with the tube prongs sliding. between the arcuate con-' tact portion and the side of the bore'making an electrical contact therewith and holding the same in'the socket I by'spring tension;
