This invention relates to mountings for electrical devices and more particularly to sockets for electron discharge devices.
In thrust type sockets for electron discharge devices and the like, the device is usually held in the socket solely through the gripping action of the contact members of the socket upon the terminal prongs of the device. a In instances where the device is subjected to shocks and vibrations, it often occurs that the engagement between the contact members and the terminal prongs is loosened so that an unsatisfactory electrical and mechnical contact results, and in some cases the device is dislodged from the socket.
One object of this invention is to securely lock an electrical device, such as an electron discharge device, in a socket therefor and thereby to prevent accidental dislodgement of the device and to maintain a satisfactory mechanical and electrical contact between the terminal prongs of the device and contact members in the socket.
In one embodiment of this invention, a mounting for electron discharge devices comprises a support which is provided with a plurality of apertures for receiving terminal prongs of the device, and a plurality of contact members within the support, disposed adjacent the apertures and adapted to engage the terminal prongs.
In accordance with a feature of this invention, means are provided for locking the device in the socket. In one form, the means includes an oval shaped or elliptical locking ring of resilient material, such as spring metal, which is mounted on the support and is adapted to encircle the base of the electron discharge device when the device is mounted in the socket. The smaller axis of the locking ring is substantially equal to or slightly smaller than the diameter of the base of the electron discharge device. When a device is to be inserted in the socket, the locking ring is flexed or distorted by the application of pressure to the end portions adjacent the ends of the larger axis of the ring so that the base of the device may pass freely through the ring and the terminal prongs on the device may be brought into engagement with the contact members. The pressure is thenreleased and portions of the ring thereupon engage the device and lock it in the socket.
In another form suitable for installations wherein manual flexing of the ring is not feasible, the locking means may take the form of a substantially circular ring having a diameter slightly greater than that of the device to be inserted in the socket. The ring may be flexed so that portions thereof bear against the device, by a tubular shield member placed over the device and bearing against a flexible support for the ring. 1
ner, the ring may be provided with apertures for receiving the bayonet pins when the ring is in its closed or locking form.
The invention and the various features there- I} of will be understood more clearly and fully from the following detailed description with reference to the accompanying drawing in which:
Fig. l is a perspective view of a mounting for electron discharge devices, illustrative of one embodiment of this invention;
Fig. 2 is a plan view of the mounting shown in Fig. l; I
Fig. 3 is an elevational view of a modification of the mounting shown in Figs. 1 and 2, and illustrating an electron discharge device locked in the socket;
Fig. 4 is a plan view of another embodiment of this invention particularly suitable for installations wherein manual flexing of the locking ring is not feasible;
Fig. 5 is an elevational view of the mounting shown in Fig. 4 illustrating the locking ring in its open form; and
Fig. 6 is an elevational view of the mounting shown in Figs. 4 and 5, illustrating the .locking ring in its closed form.
Referring now to thedrawing, the mounting shown in Figs. 1 and 2 comprises a base ill of insulating material having a plurality of apertures ll therein for facilitating the attachment of the mounting to a suitable support, and a hollow cylindrical portion 12 which may be integral with the base 10. \A plate member 13, of
insulating material, is secured to the cylindrical portion l2, as by a screw I4, and is provided with a'plurality of spaced apertures l5,v adapted to receive the terminalprongs of a device, such as an electron discharge device. A plurality of contact members, which may be of the construction disclosed in a copending application of George R. Lum, Serial No. 482,747, filed September 18, 1930, and assigned to applicant's assignee, each includes intermeshed wire helices I6 disposed within the cylindrical portion l2 and in alignment with the apertures l5, and a'metallic terminal l7 secured to the helices l6 and clamped between the plate l3 and the cylindrical portion l2.
. A pair of flexible supports or arms 3, which may be of metal, are secured to the base I 0 at ing, the locking ring I9 is distorted or flexed, as by the manual application of pressure at the portions thereof adjacent the ends of the major axis, so that it assumes a form such as shown in dotted outline in Fig. 2. A portion of a device, such as the base of an electron discharge device, may then be passed freely through the ring and the terminals of the device may be inserted into the apertures I5 and brought into engagement with the contacts it. The pressure on the ring i9 is then released, so that the ring resumes its oval or elliptical form and portions thereof engage the device to securely lock the device in the mounting.
If the device, such as an electron discharge device, to be supported in the mounting, is provided with bayonet pins, the arms It and ring l9 may be provided with apertures 20 to receive the bayonet pins.
In another embodiment of this invention, shown in Fig. 3, the supports or flexible arms 2| carrying the locking ring 22 may be substantially J-shaped to provide a longer spring. The arms 2| and ring 22 may be provided with apertures for receiving bayonet pins 23 extending from the base 24 of the. device to be supported on the mounting.
A mounting in accordance with another embodiment of this invention, shown in Figs. 4, 5, and 6, is particularly suitable for installations wherein manual flexing of the locking ring is not feasible. In this embodiment, the locking ring 25 is normally substantially circular in form, as shown in dotted outline in Fig. 4, and is of a diametersufficiently large to allow passage of a portion of a device, such as the base 24 of an electron discharge device, therethrough. When the device has been inserted through the ring, the latter is flexed by a cylindrical metallic shield 26 which engages substantially J-shaped arms 21 supporting the ring, and distorts'the ring into a substantially elliptical form, as shown in Fig. 4. The ring 25 and arms 21 may be provided with apertures for receiving bayonet pins 23 on the device 24.
Although a number of specific embodiments of this invention have been shown and described, it will be understood, of course, that numerous modifications may be made therein without departing from the scope and spirit of this invention as defined in the appended claims.
