United States Patent TUBE SOCKET ADAPTER Robert S. McCreadie, Syracuse, N. Y., assignor to General Electric Company, a corporation of New York Application October 16, 1951, Serial No. 251,553
2 Claims. (Cl. 339-154) My invention relates to electrical socket adapters and more particularly to an electrical socket adapter designed to make electrical contact engagement between two separate electrical plug connecting units. While my invention is of general utility, it has particular application in the manufacture and assembly of radio receivers. It deals in its preferred application with anew and novel electrical connecting device which may be employed in radio set manufacture readily to connect a plug or pin terminal unit secured to a radio chassis to an external electron discharge device to be plugged therein.
in the manufacture of radio sets heretofore, it has been customary to employ radio tube sockets which were permanently secured by suitable means to the radio chassis. While these sockets have been amply described in the prior art, it may briefly be said that they generally comprised an insulating body member in which there were positioned the desired number of tube socket contact members. integrally connected with these contact members were fiat terminal strips which projected from the opposite side of the socket from the socket contacts into the under side of the radio chassis. It was to these terminals that the various circuit connected components and lead wires were soldered.
While this type socket was generally acceptable, faults often occurred therein which presented a difficult prob lem in readily removing the socket contact member for replacement. In addition, the aforementioned manner used to connect the various circuit component to the socket terminals proved to be not only inefficient in that it required a number of hand soldering and connecting operations but also it was not always possible to insure uniform soldered joints.
It was therefore found desirable to change the manner of connecting the various components and lead wires to an external electron discharge device. This was done by securing a pin or plug type terminal unit to the chassis whose pins extended upwardly from the chassis and generally corresponded in number to the pins of an electron discharge device to be connected thereto. this terminal unit were mounted within an insulating base which in turn was secured to the under surface of a radio chassis. The pin terminal were hollow in nature and the necessary interconnecting lead Wires were placed in the hollow terminals in the first step of the socket assembly.
When all the leads necessary to complete the circuit were in position within the unit, the radio chassis was inverted and the outwardly extending pin members were immersed in .a bath of molten solder. The pin terminals with their inner leads in place were thus effectively soldered together in one automatic operation. Thi operation was performed by a machine known as an automatic pot-soldering machine.
It will be seen that when this method of assembly was employed a device was needed electrically to connect the soldered pin terminal elements with the proper elements The pins in 2 in an external circuit which might be an electron dis-"- charge device.
It is therefore a primary object of this invention to provide a new and improved electrical socket adapter which may connect two separate electrical pin contact terminal members.
It is a further object to provide a new and improved electrical socket adapter which is designed to be plugged into a plurality of electrical pin terminal contact members secured to a radio chassis and into which -a radio tube may be plugged, there being provisions within the adapter electrically to connect desired pin terminals of the chassis unit to desired tube elements.
For additional objects and advantages and for a better understanding of my invention, attention is now directed to the following description and accompanying drawings. The feature of my invention which are belived to be novel are particularly pointed out in the appended claims.
In the drawings:
Fig. 1. is a perspective view partly in section of my improved tube socket adapter in combination with a terminal pin unit secured to a radio chassis, and an electron discharge device plugged into the adapter.
Fig. 2 shows a portion of a radio chassis designed for use with my aforementioned adapter.
Fig. 3 is an exploded perspective view of the assembly shown in Fig. 1.
Fig. 4 shows an exploded view of the preferred embodiment of my socket adapter.
Figs. 5 and 6 illustrate a modified socket adapter constructed in accordance with the teachings of my invention. Fig. 5 is an exploded bottom view of the modified adapter. Fig. 6 is a center cross-sectional view of the modified adapter shown in Fig. 5.
As heretofore mentioned, my socket adapter 2 is adapted to complete an electrical circuit between two separate and distinct plug units 1 and 3, the adapter 2 being designed to receive one such unit 1 engageable from one surface and designed to receive another such unit 3 engageable from another surface.
Referring to Fig. l, the assembled relationship of the pin terminal unit 1, the adapter 2 and the tube 3 is clearly shown. Itwill be seen that the socket adapter member 2 receives the cylindrical pin terminals 4, which terminals are secured within an insulating base member 5. The electron discharge device 3 has the usual plurality of contact pins 6 and is shown in its engaged or plugged-in position in the socket adapter.
It will be recalled that my socket adapter is especially adapted for use in radio sets having contact pin terminal units which are secured to the radio chassis. Fig. 2 shows a portion of a chassis 9 which might be found in such a set. The pin terminal unit 1 comprises an essentially circular insulating base member 5 having .a plu rality of apertures 10 designed to receive the pin terminal members 4.
The pin terminal members 4 are inserted into the insulating base member 5 and are secured thereto by means of 'an outwardly fiaredst-op or shoulder portion 11 and an opposed peened or turned-over flange portion 12. This flange portion 12 i bestshown in Fig. 1.
The pin terminal unit 1 comprising the insulating base member 5 and the hollow cylindrical pin terminal members which, it will be seen, extend upwardly from the upper surface 13 of the radio chassis 9, is secured by means of rivets or eyelets 14 to the chassis 9. The pin terminal unit 1 is shown secured to the under surface 15 of the chassis 9, the pin terminals 4 extending through a suitable aperture 16 in the chassis 9 for engagement with the socket adapter 2. Two pin terminal units 1 are shown, while in outlined form there are illustrated various circuit components 17 and 18, whose connecting lead wires might conceivably be soldered into the hollow cylindrical pin terminal members 4. These might comprise, for example, a condenser 17, a resistor 18; The lead wires 19 are initially inserted within the pin terminals 4 and then are soldered in a pot-soldering operation.
The radio chassis 9 shown in its assembled form with the leads positioned within the terminal members but not soldered therein is turned upside down and the pin terminal members are immersed in a bath of molten solder. The solder enters the pin terminal members at the ends 21 thereof and solders the terminal members to the lead wires within it. This operation of simultaneously soldering all the pin terminal members is accomplished by a so-called automatic pot-soldering machine.
My improved socket adapter is then employed to connect the pin terminal members 4 to desired contact pins 6 of an electron discharge device 3. Note that in the exploded perspective view in Fig. 3 the upper surface of the adapter 2 has a plurality of apertures 25 corresponding in number to the pins 6 of the tube to be accommodated within the adapter 2.
Referring again to Fig. 1, it will be seen that the socket adapter 2 is placed onto the pins of the pin terminal unit 1. The cross-sectional portion of this figure shows one cylindrical pin terminal member 4 having lead wires 19 soldered therein. The solder 20 is admitted to the pin member 4 during the soldering operation through the hole 21 of that member.
This pin terminal member 4 is engaged by a pin receiving socket contact unit 22 located within the discshaped insulating adapter 2. The tube 3 is plugged into the adapter 2 from the oppositesurface from the pin terminal. Contact pin 6 of the tube is engaged by a portion of the pin receiving socket contact unit which completes the electrical circuit from the pin terminal 4 to contact pin 6.
This cross-sectional portion further shows that my adapter 2 may be constructed, as far as its insulated portion is concerned, with two superposed insulating members 23 and 24. The member 23 houses the electrical socket connectors while the member 24 forms an insulating cover permitting access to only a desired ring of socket contacts corresponding to the number of pins of the tube. A portion of the insulating cover member 24 effectively shields from human contact the pin terminal members 4 and their enclosing socket contacts within the insulating housing member 23.
It may be mentioned at this point that my socket adapter is also advantageous from the safety point of view since it effectively encases and insulates all the pin terminal members 4 and socket contact units 22 which might otherwise be exposed to bodily contact to persons manipulating the units.
With the assembly illustrated in Figs. 1 and 2, comprising the radio chassis9, the pin terminal unit 1, the
The various component parts of my socket adapter are best shown in Fig. 4 in which the largest element comprises the disc-shaped insulating housing member 23 having opposed surfaces. As will be seen, this member incorporates a plurality of plug or pin admitting openings or apertures 25 and 26 within which there are positioned plug receiving socket contact units 22. These socket receiving apertures are arranged in two concentric rings of openings, an inner ring of apertures 25, and an outer ring 26. The openings are spaced-apart and there are a cone sponding number of openings in each ring.
The apertures 25 and 26 are in radial alignment and may be said to comprise paired-openings and therefore the adapter in one sense incorporates a plurality of paired openings. A pin receiving socket contact unit 22 is inserted within each of the paired-openings.
Each pin receiving socket contact unit 22 may comprise an integral unit made up of two essentially cylindrical pin receiving socket contact members 27 and 28 connected by a web or bridge portion 29. It will be appreciated that this unit might very well be composed of separate pieces in which each socket contact member 27, 23 comprises a cylindrical piece with a tang portion, the tang portions of each member being connected together by suitable means such as by solder.
Each of these pin receiving socket contact units 22 is inserted within one of the paired- openings 25, 26 in the insulating body. As shown in Fig. 4, an inner socket contact member 27 is adapted to fit into an aperture 25 in the inner ring of openings while member 28 fits in the aperture 26. The cylindrical socket member 27 may have a jaw-shaped portion 30 designed to grip a tube contact pin inserted therein. The other socket contact member 28 is positioned within an adjacent aperture 26. A web portion 29 connects the adjacent socket contacts.
It will be evident that any suitable means may be employed to secure the pin receiving socket contact units 22 within the housing. I have shown in Fig. 4 an insulating cover member 24 which performs this functiOn. This cover member has a single ring of spacedapart apertures 31 extending therethrough corresponding in position and in number to one of the rings of spaced-apart apertures in the insulating housing member 23. In the exploded view illustrated, the holes 31 are in registry with the inner ring of openings 25 when in superposed position so as to admit correspondingly positioned tube pins into the socket contact members 27 located within the housing 23. T
The cover member 24 is secured to the housing member 23 by means of an eyelet or rivet 32 which extends through centrally located apertures 33 and 34 in both the cover member and the housing member. Of course, other conventional means may be employed to perform this function. The cover member 24 not only serves to center the tube pins With respect to proper tube socket contacts located within the housing, but also functions to insulate the contact units 22 held in place at the upper surface of the adapter housing.
A circular under-cut portion 35 is provided on the upper surface of the insulating housing member 23 so that cover member 24 will fit over the socket contact unit 24 and fit flush with central hub portion 36 and outer rim portion 37. The under surface of the cover member when secured to the housing by rivet 32 makes engagement with the upper surface of the insulating housing member at the hub portion 36 and the outer rim portion 37. V
I have shown in Figs. 5 and 6 a modified construction of my socket adapter in which the cover member is eliminated and in which the openings 3% in the insulating member are elongated in shape. It will be noted that I provide in this alternative arrangement a different type of socket contact unit 40 from that heretofore disclosed and a novel grounding clip 41.
Referring to Figs. and 6, I have shown a one-piece insulating housing member 39. In Fig. 5 this body member is shown in inverted position while in Fig. 6 it is shown in its normal position. As shown in Fig. 5 there are a crcular series of elongated openings 38 in the under surface of the member 39. There are also, as shown in Fig. 6, a corresponding number of circularly placed spaced-apart apertures 43 in the upper surface, which connect with elongated openings 38 in the under surface.
A plug-receiving socket contact unit 40 is provided which functions in a manner similar to the socket contact unit 22 described in connection with Fig. 4. However, in this case each socket contact unit 40 is snapped into engagement within each elongated opening 38. The contact unit 40 comprises essentially a U-shaped outwardly biased spring clip 46, 47 in which the connecting portion forms an essentially circular pin receiving contact portion and in which the oppositely disposed spacedapart wing portions 46 include other pin receiving contact members 47. Outwardly flared tip portions 48 from the wings 47 engage suitable autments within the housing 39, securing the contact unit 40 within same.
In addition to the socket contact unit, I provide a grounding contact member 41 mounted in an additional aperture 54 in the body member 39. This member 41 includes a spring arm 50. One use of this spring arm 50 is shown in Fig. 6 in which a tube 51 having a metallic shielding base member 52 is engaged by the spring arm. Of course, an outer metallic cylindrical shielding member, not shown, might be slipped over the tube 51 and would then be engaged by the spring arm.
The grounding contact 41 includes, in addition to portion 50, a pin receiving contact portion 53 which may be positioned at the axis of the body member. It will be seen that this grounding contact member 41 snaps into the T-shaped elongated opening 54 in the body member and is held in place within the housing by means of the outwardly fiared tabs 55. These tabs 55 are positioned between the portion 53 and the portion 50 to grip the corresponding portion of the side walls of the aperture 54.
The relationship between the various components described chiefly in connection with Fig. 5 is further illustrated in Fig. 6 where the grounding contact member 41 and its spring finger 50, which extends through the aperture 56 in the upper surface contacts the lower metal portion 52 of the vacuum discharge device 51.
This Fig. 6 also shows the unit 41 in place in member 39 with its arms 55 engaging the side Walls of the aperture to hold it in place. The position of the socket contact unit 40 within the body cavity is also illustrated showing the pin receiving tubular contact section 45 and the oppositely disposed wing contact portions 47 which are shown in engagement with one of the pins 57 of vacuum tube 51.
It will thus be apparent that I have provided a novel tube socket adapter which is of particular application in the mass assembling of radio receivers in which a pot soldered terminal unit is to be connected to an electron discharge device.
While certain specific embodiments of my invention have been described it will, of course, be understood that various other modifications may be made without departing from the principles of the invention. The appended claims are therefore intended to cover any such modifications as fall within the true spirit and scope of this invention.
What I claim as new and desire to secure by Letters Patent of the United States is:
