COMBINED SOCKET AND MOUNTING PLATE Filed Jan, 21, 1958 26 1m Z6 1? w M 20- j Patented June 18, 1940 UNITED STATES PATENT OFFICE COMBINED SOCKET AND MOUNTING PLATE Arthur J. Schmltt, Chicago, Ill.
Application January 21, 1938, Serial No. 186,165
1 Claim.
' This invention relates to combined socket and mounting plate more particularly for sockets for radio electronic tubes in 'which the socket is mounted in an opening on a radio chassis or the like.
The molded one-piece socket has many advantages over the conventional socket of laminated insulating material, but problems have been encountered in attaching the molded socket to the chassis. For many years the standard form of radio socket, which has been conventionally of the laminated type, has been diamond-shape with rivet holes near the points of the diamond, and one of the problems encountered with molded sockets has been the maintaining of a structure of this general shape so that the molded socket may be secured interchangeably with a. laminated socket on the radio chassis.
Instead of molding the insulating body in diamond-shape, since there are certain distinct advantages in maintaining the generally cylindrical shape of the molded insulating body, it has been proposed to provide a so-called adapter or mounting plate of sheet metal in association with the molded insulating body, and to which the latter is secured. In my co-pending application Serial Number 152.478, filed July 8, 1937, I have shown such an adapter plate separably secured to the molded body. but such attachment of the body and plate is sometimes objectionable in that it is difficult to make the interengage.. ment of the parts so tight as to be entirely free from slight movement and consequent vibration which may affect the radio reception.
In another co-pending application Serial Number 107,526, filed October 26. 1936, I have disclosed an alternative method of securing the body and plate together in which the plate is molded into the body. this latter method being highly preferable by achieving a tight and vibrationless attachment of the parts and making the body and plate in effect an integral unitary socket. The present application is a continuation in part of the said disclosure of my co-pending application Serial Number 107,526.
The present invention aims to provide such a unitary body with molded-in plate which possesses enhanced rigidity while preserving the advantages of the diamond-shape. A further ob- ,iect is the provision of a mounting plate of this general type affording novel means of mounting on the radio chassis other than by riveting.
The present invention also is inclusive of both product and method.
Other objects and advantages will be readily ing body is molded thereabout;
Figure 4 is a similar view of a modified form of plate in preliminary form; 1
Figure 5 is a side elevational view of the plate of Fig. 4 with an insulating body molded therein, and with the plate tongues in intermediate position;
Figure 6 is a view of the structure of Fig. 5 secured to a radio chassis with the plate'tongues in final position; and
Figure 7 is a .view somewhat similar to Fig. 6 but showing an alternative form of mounting the socket to the chassis.
Referring in detail to the illustrative construction shown in the drawing, the numeral Ill indicates in cross-section a panel of the usual radio chassis or the like, upon which the tube sockets are to be mounted. The panel commonly is provided with a circular opening H therein which is just slightly larger than the cylindrical insulating portion I! of the socket in which the contacts l3 are held to engage through recesses N in the body with the prongs of a radio vacuum tube (not shown). The contacts l3 are desirably of flat sheet metal having at their upper ends the legs I 30 between which the prong of the radio tube is frictionally engaged when received in the recess I 4, Transverse grooves Ha extending laterally from the recess It not only permit the legs I311 to be received in the body I! but also the tail I3b of the contact, which as shown is preferably Y wider than the cylindrical portion of the recess H. when the tail l3b has been passed down through the slot Hb in the lower part of the recess I l the tail may then be bent or distorted to secure the contact against displacement upwardly in the body, as shown in my co-p'endlng application Serial Number 107,526. The shoulders so We formed at the junction of the legs I31: and the tail lib engage the shoulder c in the recess H and prevent downward displacement of the contact from the socket. Apertures lid in the tall are for the II usual soldered electrical connections. A central passage i2a in the body I2 receives the usual central locating plug on the vacuum tube and may include a keyway for fixing the relative r0- tative position of the vacuum tube and socket, this being well known to the art and not necessary to be here shown. Commonly the panel In is. provided with diametrically opposite perforations IE3 at the margins of the opening ll.
Referring first to Figs. 1, 2 and 3, the cylindrical insulating body I2 is held in the opening H by the mounting plate IE (to which it is secured as later described), which plate, as best seen in Fig. 3, is of diamond-shape having the holes H, in its opposite comers l8, which are made to register with the holes IS in the panel i0. As shown in Fig. 2, rivets l9 secure the mounting plate It across and just beneath the opening H in the panel so that the upper end of the cylindrical body l2 projects upwardly just slightly through this opening, and is therefore readily accessible for insertion therein of the prongs of the vacuum tube.
In accordance with the present invention, it will be seen that the central portion of the plate 16 has a central cut-out 20 therein, and the plate is adapted to be formed in large quantities by a stamping operation from sheet metal, not only to provide thiscentral cut-out 20 with its continuously integral margin, but also to form the portions of the plate margining this cut-out, as next described.
Diametricaliy opposite each other and desirably aligned with the holes I! in the plate are the inwardly directed lugs 2| which project into the cut-out 20 but preferably in the plane of the plate l6. On each side of each of the lugs 2i is then formed a notch 22. Extending between the pairs of notches 22 and for the remainder I of the inner circumference of the cut-out 20 are the diametrically opposite portions 23 of this margin which are distorted somewhat out of the plane of the plate It, as in this instance by being depressed, as best shown at 24, Fig. 1. The distorted portions 23, as will be seen, are a-rcuate substantial portions of the inner circumference of the cut-out 20. The insulating body l2, which may advantageously be of Bakelite, is next initially molded in the cut-out 20, as is well known in the art, and need not be described. It is sufficient to'state that when so molded in the cut-out 20, the body i2 as here shown is of sufficient final diameter, as best shown in Fig. 1, so
that the entire margins of the cut-out 20 in-,
when the body l2 and the plate It are molded together they become in efiect an integral unitary socket preserving the advantages of the flat plate l8 which does not interfere with the insertion of the cylindrical body I2 in the opening H in the chassis panel, and at the same time enhances the strength and rigidity of the central portion of the plate l6 and particularly the otherwise somewhat weak sides 25 of the plate. In other words, distorting the inner margins 23 transforms the sides 25 into beams having tension and compression components, these components being furthermore embedded within the body l2 and the material of the body l2 so flowing thereabout as to further uniquely and positively interlock the body and plate together against any possibility of vibration of one with respect to the other.
Turning now to Figs. 4 to 'I inclusive, the plate might be of the somewhat modified form 26, the central cut-out and its margin being advantageously the same, but the outwardly projecting tongues 21 being formed in place of the ends I8. Insuch case the tongues 2-1 may first be turned up as at 28, Fig. 5, then inserted through the holes IS in the panel l0, and then clinched over the panel as at 29, Fig. 6, thus seeming the combined socket and mounting plate to the panel without the riveting operation indicated in Fig .2.
As a still further method of mounting, the tongues 21 could be left flat, that "is, in the plane of" thepiate 26 as indicated in Fig. 7 and spotwelded to the panel l0 as at 30.
Such changes may be made as fall within the scope of the following claim without departing from the invention.
Having described my invention, I claim:
A device of the class described embodying a flat sheet metal annular plate having an integral generally circular inner margin, a cylindrical socket body of initially plastic insulating material molded within said annulus with the inner margin of the plate embedded within said molded body, diametrically opposite substantially quarter annulus segmental sides of said inner margin being by performing prior to molding inwardly and axially extended out of the main plane of said plate within the body whereby said margin sides function therein as reinforcing beams hav ing both tension and compression components as well as providing a positive non-rotative interlock with said body, said plate having exterior diametrically opposite mounting extensions aligned transversely substantially ninety degrees to said segmental sides.
