9 Claims.
1 The present invention relates to shielded mountings for radio 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 an improved tube socket mounting and shielding cover which will be simple in construction and efiicient in operation to prevent resonance and vibration in high frequency'circuits.
A further object of the invention is the provision of an improved tube socket mountingypan ticularly for small minature base tubes, that eliminates the necessity for separate fastenings, such as screws, rivets and the like, and one that provides means for engagement with a shielding cover to hold the cover tightly against the chassis or support.
Other objects and advantages f the invention will be apparent to those skilled inthe art from a consideration of the accompanying drawings and annexed specification illustrating and describing a preferred embodiment of the invention.
tithe-drawings:
Fig. 1 is a side elevation of a typical miniature base tube installation embodying the invention;
Fig. '2' is an enlarged horizontal sectional view thereof as taken on the line 2-4 of Fig. 1;
Fig. 3 is an enlarged vertical sectional view of the installation as taken on the line 3-3 of Fig. 2;
Fig. 4 is a detail perspective view of the tube socket mounting ring or saddle;
Fig. 5 is a perspective view of the shielding cover; and
Fig. 6 is a horizontal sectional view of the shielding cover as taken through the saddle lugreceiving slots thereof.
Referring more particularly to the drawings, the tube socket mounting and shield support advantageously comprise a saddle which may be a ring-like member adapted to engage the socket over a. flange thereof, and retain the socket in operative position on an apertured chassis by means of bendable arms or wings forming a part of the saddle, the saddle having means such as lugs or tabs to engage and hold the shielding cover.
In the illustrated embodiment the chassis I may be formed with a suitable aperture 2 to receive the body portion 3 of a socket member of suitable deslgn. Such socket members are preferably formed with an outwardly extending rim or bead 4 and customarily are provided with a plurality of tube prong-receiving apertures 5'having contacts 6 which may be connected to the various electrical circuits of the apparatus. The chassis aperture 2 is of a size to receive the'body of the socketbut of less diameter than the bead or rim 4 so that the socket is supported in the chassis aperture by engagement of the rim 4 with the supper surface of th chassis. The chassis l may be further provided with a plurality of notches or recesses l communicating with the aperture'Z.
The socket member 3 is retained in position in the aperture 2 of the chassis I by means of a thin ring-like saddle member ID overlying the rim 4 and formed with angularly extending arms ll adapted to extend through the notches l of the chassis and be bent outwardly under the chassis as illustrated in Fig. 3. Thus the rim 4 of the socket member is securely clamped between the chassis I and the saddle member Ill by a simple mounting that avoids the necessity of separate iastenings such as rivets, screws and the like.
The socket 3 customarily supports the tube 8 of the electrical apparatus and electrically connects it to the circuits of the apparatus through the usual tube prongs which are inserted in the openings 5 and connect with the contacts 6.
It is frequently desirable in such electrical apparatus to provide a shielding cover for the tube 8 and this is particularly desirable in high frequency circuits.
The shielding cover or can 15 is of a size to enclose the tube and carries an inner coiled spring l-G adapted to engage the outer end of the tube 3 and press it securely against the socket 3. The cover l5 has an inner open end adapted to surround the socket 3 and make a grounded contact with the chassis I, and preferably this open end of the cover l5 may be outwardly flanged as at H to provide a substantial area of contact with the chassis and effect a good ground connection therewith.
According to the invention, the shielding cover I5 is retained in operative position over the tube and in grounding connection with the chassis by means of a locking element on the saddle for lockin engagement with the can.
According to the illustrated embodiment of the invention shown in the drawings, the saddle is provided with one or more lugs or tabs l2 as 11- lustrated in Fig. 4, and these tabs preferably extend laterally and radially beyond the periphcry of the saddle ring Ill.
The sides of the shielding cover or can l6, adjacent the open end, are longitudinally slotted as at it, as by forcing th metal of the sides outwardly for a limited depth to permit the open cover to be positioned over the saddle ring and lugs 12. These longitudinal slots l8 communicate with arcuate cam-shaped or inclined slots l9 adapted to receive the lugs l0 upon rotation of the shield about the socket. The ends of the slots l8, remote from the slots l8, may vbe depressed to provide seats 20 for the lugs 12 so that the cover will be retained in its tightened position against the chassis. As will be apparent in Fig. 1, the arcuate slots H) are inclined away from the flanged base end ll, so that as the shielding cover is rotated around the saddle, the lugs l2 ride on the inclined faces l9a at the edges of the slots [9, to force the flanged end of the cover l5 into tight grounding engagement with the chassis. The slight notches 2U20 at the ends f the slots l9 receive the lugs l2|2 tight- 1y to prevent accidental unfastening.
From the above it will be apparent that the invention provides a new and improved socket mounting in the form of a saddle that may be attached to a chassis without additional fastenings such as screws, rivets and the like and which is provided with means to engage and hold a shielding cover tight against the chassis to reduce resonance and vibration in high frequency circuits.
The invention is not to be restricted to the specific embodiment shown in the drawings as the scope of the invention is best defined in the appended claims.
I claim:
