SAMUEL SIEGEL, OF NEW YORK, N. Y., ASSIGNOB TO AEROVOX WIRELESS CORPORA- TION, A CORPORATION OF NEW YORK.
OONNECTER FOR RADIORECEIVERS.
Application filed novcmber ao, 1924. Serial No. 750,966.
My present invention relates primarily to radio receivers and is more especlally concerned with electrical connectors for placing the receiver in circuit with the aerial, ground and batteries.
It is among the objects. of the inventlon to provide simple means for expeditlously connecting a receiver into circuit, without the possibility of error in connection and without the need for any special knowledge or skill. For this purpose, I provide a multi-contact connection of the plug and socket type, the plug and socket members carrylng a plurality of coacting terminals to which lead wires or other suitable types of electrical conductors are adapted to be connected.
One of the members, preferably the socket member is secured to the housing of the receiving set and its terminals are connected to the bus bars or Wires leading from the tubes and control apparatus, while the mating terminals of the other member connect with electrical conductors leading to the batteries, ground, aerial and other exterior ap paratus.
The receiving sets may be built up with the socket members forming a permanent part thereof, while the plug members may be relatively permanently connected to asso- In order to set up the apparatus for use, it is merely necessary to insert the plug into the socket, thereby establishing all of the necessary connections. Testing or comparing a number of receiver sets merely involves the retraction of the plug from the socket from one set and its insertion into the socket of another set.
Other features of the invention relate to the specific types of plug and socket terminals, both of which are adapted for ready attachment to electrical conductors, and the manner in which the plug and socket members are automatically guided into correct mating relationship so that there can be no short circuits or cross circuits. The invention will be better understood from the accompanying drawings, wherein:
Figure 1 is a diagrammtic view i'llustrating a radio set embodying the invention.
Figure 2 is a transverse sectional view through the assembled plug and socket n1embers.
Figure 3 is an outer face view of the socket member.
Figure 4 is a plan view of a portion of the; plug member and its associated termina s. beFigure 5 is a face View of the plug memr. Figure 6 is a plan of the inner normally concealed end of the socket member.
Figure 7 is a face view of the plug member illustrating a modified type of a guide for insurin correct co-re'lation of the plug with its soc et.
In Figure 1 reference character 10 indicates the conventional casing of a radio receiving apparatus equipped with any appropriate number of adjusting knobs 11 and dials 12 on its front face and having an opening 13 in its rear wall adapted to accommodate the socket member 14 of my improved electrical connecting device. Socket member 14 is preferably a circular plate fitting the opening and formed with a pair of diametrically opposed apertured lugs 15 receiving screws 16 retaining the members in place against the back panel or wall of the casing. The lugs are preferably disposed on the inside of the casing so that from the outside the socket member presents the appearance of a circular plate of insulating material preferably flush with the rear panel and having a plurality of circumferentially disposed openings 17 therein. Disposed centrally of the socket member and extending inwardly from the plate portion thereof is a boss 18 formed at its inner end with an annular flange 19. The terminals of the socket member comprising spring fingers 20, the intermediate portions of which are disposed in longitudinal grooves 21 in the flange 19 and permanently secured in the grooves by screws 22 threaded into bores 23 in the flanged end of the boss, or, if desired, by rivets. Each finger terminates just short of the plate portion 14 of the socket member and includes a V shaped oflset portion 21 projecting beyond the edge of an associated opening 17. The other ends of the terminals 20 are-preferably apertured as at 25 and are adapted to be bent over into the position illustrated in Figure 6 and in dotted lines in Figure 2. By bending the fingers over. so their ends are approximately parallel with the plate, the operation of soldering the wires, bus bars or other conductors 26 thereto is expedited. When the solder is applied to hold the wires in place it flows into the openings 25 and insures "a firm connection between the bent ends of the fingers and. thev wires. In order to facilitate the proper attachment of the wires to the socket member, the fingers may display suitable indicia as indicated in Figure 6, the markings on the fingers identifying the separate terminal members. and indicating which of'the wires soldered thereto is to i 1 be connected to. ground,-aerial, -A battery,,i
detector. The plug, member of-the co'nnecter' also includes a-molded plate 27 of insulating ma.- terial carrying a circumferentially' disposed", series of terminal pins 28 adapted. to enter, the openings 17 in the socket. The pins 28 are referably shouldered as indicated at '29 to t within suitably prepared recesses in the face of the plate27 and include reduced threaded extremities 30 extending through the plate 27 and clamped at the rear face thereof by nuts 31, and 32. Obviously the pins may be moulded in the plate 27. These nuts incidentally serve to clamp between them the flattened portion 33 of a terminal 34 to which the ends of lead wires 35 are soldered. The pins 28 are provided with rounded heads 36 defining grooves 37 into which the oilset V shaped portions 34 of the fingers 20 snap as the plug member is pushed home. The headed pins cooperating with the V shaped extensions of the terminal fingers 20 to insure an effective lock and a good electrical connection and at the same time ermit the plug to be inserted or removed without substantial manual eiiort.
It will be noted that the V shaped extensions of the terminal fingers will act to automatically center the plug, so that inaccuracies in the positioning of the apertures in socket 14' are automatically accommodated.
The rear face of the plate 27 is molded with a plurality of radial partition members 38 which serve to separate the " nuts 31, 32, and terminals 34 from each other, so that there'is no danger of a short circuit there occurring. All of the lead wires 35 are bundled into a suitable cable member 39 over which I slip a cap member 40 which serves as a housing for the terminal devices and connections on the rear face of the plate 27. The cap preferably has screw threaded engagement with the plate as indicated at 41 and is locked against unthreading by set screw 42. The various lead wires from the cable 49 carry at their free ends conventional terminal members of any suitable desuch as those indicated at 43, these termmal members being adapted for connection to the battery, ground, aerial, etc.
To insure the correct attachment of the lead wires 35 to the exernal apparatus and to insure proper co-relation of the pins 28 and fingers 20, the lead wires 35 may be provided with appropriate indicia, (not shown),
and means be rovidedfOr insuringthe insertion of each pm'28' throu h-its proper wires 35', I'
To properly a llocate the pins in the holes, Imay employ a separate guide pin 28 considerably larger than any of the his 28 and receivedv 'ina correspondingly arger hole 17?. Inasmuch as it IS impossible to insert the guide pin 28 in any hole except'the one repared for it, there is no danger of crossmg the electric circuits. The guide pin either may or may not be used to establish one of the electrical circuits. An alternative arrangement of guide is illustrated in Figure 7 wherein the plug member 50 car ries at one edge, a projecting lug, 51,adapted to be received in a cooperating recess prepared for it in the socket member.
. The broader features of the connecter disby the use of the socket, since the socket eliminates the necessity for boring numerous holes in the panels of the'instrument housing, does away with various binding posts and other forms of terminals and materially enhances the attractive appearance of the completed set. With the socket applied to the back of the box, all of the lead wires will be effectively concealed and only the usual dials will be visible at the front panel. connection plug may, if desired, be provided at the front or tli set, or even throughthe floor thereof.
It will thus be seen that there is hereinv described apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objectsof the invention and is well suited to meet the requirements of practical As many changes could be made in the above construction and many a parently widely difi'erent embodiments of t 15 invention could be made without departing from Ill. Obviously, however, thejmultiple e side panel of the receiving arranged, and
the scope thereof, it is intended that all matter contained in the above description or shown invthe accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. A multiple contact socket for use with a panel having an opening andadapted to be secured in said opening with its outer face exposed and substantially flush with the outer face of the panel, comprising a face portion having a plurality of plug receiving openings therethrough circumferentially a hub having an outer diameter less than the diameter of the circle in which the plug receiving openings are arranged, said hub portion having a plurality of spring contacts in alignment with the openings and adapted to engage plugs projected through said openings.
