5 Claims.
The present invention relates to combined tube sockets and shield retainers for thermionic and like tubes and aims generally to improve existing constructions of that type.
One of the primary objects of the invention is the provision of a combined tube socket mounting and shield retainer which may be attached directly to the metal chassis of a radio apparatus and which will provide a good ground connection between the shield and chassis.
A further object of the invention is to provide an efficient shield retainer of simple construction which is economical to manufacture.
Illustrative of the invention, reference is made to the accompanying drawing, in which:
Fig. l is a plan view of the complete socket, tube and shield assembly;
Fig. 2 is a plan of the socket and shield retainer mounting assembly;
Fig. 3 is a central, vertical sectional view of the assembly as taken on the line 3-3 of Fig. 1;
Fig. 4 is a detail perspective view of the socket and shield retainer mounting; and
Fig. 5 is a detail perspective view of the shield.
Referring more particularly to the drawing, the socket and shield retainer mounting advantageously comprises a socket ring and retainer formed with a metal base l which may be directly attached to a metal chassis ll of a radio or like apparatus by suitable means, as for example rivets it. The ring base I0 is preferably formed with an upstanding annular boss 13 of size equal or conforming to the cross-sectional size and shape of the shield, and an aperture l4 therein provides a seat for a socket and contact assembly l upon which is mounted the pronged thermionic tube l6, as is customary. The particular specific construction of the socket and contact assembly I5, as well as the tube l6, may be of any type suitable for the purpose and forms no part of the present invention.
The base ID of the ring member is preferably formed with oppositely disposed upstanding arms I! of resilient material which are spaced laterally a slight distance from the sides of the boss l3 so as to permit the shield to be inserted on the boss inside of the arms H. The upper portion of the arms I! is preferably formed with a downwardly extending finger or prong l8 which advantageously may be cut from the metal of the arms for the purpose of engaging a part of the shield l9 positioned over the tube 16.
The shield l9 may be of any suitable construction but preferably is in the form of a metal sleeve having an open lower end adapted to pass over the boss l3. The body of the shield is preferably formed with one or more beads 20 extending outwardly from the walls and preferably these beads are spaced around the periphery of the shield so that the spaces between them are greater than the width of the finger or prong 18 on the arms 11. Each head 20 has a centrally located stop 20 at least as wide as a prong [8 (Figs. 1 and 5) so that the end of the prong I 8 may be located in the stop and prevent accidental rotation of the shield l9 to unfastened position. A coil spring 2| is positioned within the shield between the end of the tube l6 and a portion of the end wall of the shield and serves to hold the tube in position on the socket l5 as well as to maintain the beads 20 of the shield in engagement with the fingers or prongs l8 and to insure a good ground connection between the shield and fingers l8.
In assembling the mounting, tube and shield, a socket and contact member 15 of desired construction is assembled in the aperture M of the socket and retaining mounting and the base l0 thereof is then directly attached to the metal chassis H by suitable means such as rivets l2, the socket member I5 extending through an aperture in the chassis as is usual. The tube l6 may then be mounted on the socket in the usual manner, as by inserting the prongs thereof in the prong-receiving apertures of the socket. The shield is then positioned over the tube and as its open end is forced over the boss I 3, the spring 2| is compressed and the beads 20 are forced past the fingers I 8 on the arms I! and effect a snap fastener locking engagement therewith in the stops 20*. In this position the coil spring 2| not only forces the tube to proper position on the socket but forces the beads 20 against the prongs [8 to insure a good ground connection between the beads 20 of the metal shield and the fingers l8 of the arms I1.
When it is desired to remove the shield for any purpose, it may be pressed and rotated on the boss l3 so that the fingers l8 will align with the intervening spaces between the beads 20, in which position the shield may be readily removed. In fact, when in such position the spring 2| aids in ejecting the shield from the boss and tube.
Preferably, the socket-receiving ring and arms I! are formed from a single piece of metal as illustrated, but obviously all of the advantages of the invention may be obtained by forming the arms on a separate base secured in position between the base Ill and chassis ll.
Although I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby because the scope of my invention is best defined by the following claims.
I claim:
1. A tube socket and shield retainer mounting for a thermionic tube and an enclosing shield comprising a base formed with a tube socket receiving opening therein, a shield retaining boss on said base, and a snap fastener means on said base for engagement with the sides of said shield.
2. Tube socket and shield retainer means for shielded thermionic tubes and the like comprising a metal base attachable directly to a metal support, said base being formed with an upstanding boss provided with a central aperture, said boss providing a fitted support for a metallic shield, and laterally spaced snap fastener means connected to said base for engaging said shield for holding it in position on said boss.
3. Tube socket and shield retainer means for shielded thermionic tubes and the like comprising a metal base attachable directly to a metal support, said base being formed with an upstanding boss provided with a central tube socket receiving aperture, said boss providing a fitted support for a metallic shield a plurality of upstanding resilient arms connected to said base and spaced laterally from said boss, and means on said arms for snap fastener engagement with said shield for holding it in position on said base.
4. Tube socket shield retainer means for shielded thermionic tubes and the like, comprising a metal base attachable directly to a metal support, said base being formed with an upstanding boss provided with a central tube socket receiving aperture, said boss providing a fitted support for a metallic shield spaced fastening members disposed along the margin of said base extending outwardly and upwardly therefrom for snap fastening engagement with a shield fitted on said boss to hold it securely thereon.
5. Tube socket and shield retainer means for shielded thermionic tubes and the like, comprising a metal base attachable directly to a metal support, said base being formed with an upstanding boss provided with a central tube socket receiving aperture, said boss providing a fitted support for a metallic shield spaced fastening members disposed along the margin of said base extending outwardly and upwardly therefrom, the upwardly extending portions of said fastener members being formed with inwardly extending tongues for snap fastener engagement with a shield fitted to said boss.
