A. G. ROSA ELECTRICAL TERMINAL CONNECTOR Filed Oct. 17, 1944 INVENTOR. flN THOA/Y 6 F050.
A T TOR/V5 K Patented Aug. 24, 1948 UNITED STATES PATENT OFFICE ELECTRICAL TERMINAL CONNECTOR Anthony G. Rosa, Lyndhurst, N. J.
Application October 17, 1944, Serial No. 559,093
This application is a continuation-in-part of my patent application, Ser. No. 507,681, filed October 26, 1943, for which the U. S. Patent No. 2,366,459, issued January 2, 1945, and it relates to an electrical terminal connector.
From past experiences it has been found that electrodes used in vacuum tubes, and the like, when welded, are likely to develop leaks detrimental to the functioning of said tubes. This is particularly true, for example, in the case of radar tubes, wherein the glass tube is fused to the electrodes, and where it is essential to have the electrodes at each extreme end of the glass tube in an exact concentric position.
Heretofore such electrodes were welded to an electrode cup, or, as is shown in my co-pending application referred to above, said cup was perforated to permit the entrance of the threaded pin member through the cup into the electrode, relying upon a tight clamping fit against leaks.
Since the clamping method by welding of the parts is not sufficiently dependable to assure an airtight joint, it is the purpose of this invention to provide for an electrode of the kind described herein, in which no parts of the cup member are exposed to a. break in the surface of said cup member by either perforation or welding.
It is a further object of this invention to provide an electrode cup with proper ridges, which, when bent over, will securely hold the parts, such as an electrode, pin, etc., in their respective places.
It is another object of this invention to assure the exact and important concentric location of the electrode and pin within the said cup.
It is a still further object of this invention to provide for a clamping securing means, which will permit of the utilization of simple dies in the said operation.
With the above and other objects in View, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing, forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:
Figure 1 is a sectional view of the cup-shaped member, the electrode and the pin, disassembled.
Figure 1 is a top plan View of the cup-shaped member.
Figure 3 is a sectional view through the cupshaped member with the electrode and pin in position,
Figure 4 diagrammatically illustrates the die members for clampin the electrode and pin into their respective position relative to the cupshaped member.
Figure 5 illustrates the electrode and the pin after the clamping operation, with the pin die clamp removed. 7
Figure 6 is a top plan view of Figure 5, with the electrode clamping die removed.
Figure '7 is a sectional View of the cup-shaped member, with parts broken off, and showing a slight modification in the construction of the bottom of said member.
Figure 8 is a partly diagrammatic and partly side elevational view in section, showing the bottom of a cup-shaped member made from a blank, for instance, by a machining operation.
Referring more particularly to the drawing, the electrode I0 comprises a cup-shaped member I I, and electrode I2, and a pin I3.
The cup-shaped member consists of the conventional flange I4, side wall I5 and bottom Hi.
The bottom I6 has pressed therein a ridge I1 extending inwardly into the cup, and a smaller ridge 18 extending outwardly from the cup.
The inside diameter of the ridge II conforms in size to the bottom edge 20 of the cone-shaped extension 2I of the electrode I2; while the inside diameter 22 of the smaller ridge I8 conforms in size to the diameter 23 of the cone-shaped end 24 of the pin I3; said pin is preferably threaded as at 25.
In assembling the electrode unit, the ballshaped electrode I2 and the pin I3 are placed in their respective positions in the cup-shaped member I I, as shown in Figure 3.
Figure 4 diagrammatically illustrates the two dies 30 and 3|, both of which are provided with bevelled end portions 32 and 33, respectively, and which end portions engage the margins 34 and 35 of the ridges I1 and I8, respectively.
As the dies 30 and 3i are moved in the direction of the arrows 36 and 31, the bevelled surfaces or end portions 32 and 33 of the dies 30 and 3| will cause the ridges I1 and I8 to bend inwardly; the inside walls 38 and 39, respectively, of said ridges will then firmly engage and form a tight and solid unit with the cone-shaped portions 2| and 24 of the electrode I2 and pin I3, respectively, thus securely locking said electrode and pin in proper position.
The ridge portions I1 and I8 illustrated and referred to formerly herein, may, as shown by I'm in Figure '7, be formed with its walls much closer together, in order to possibly obtain a more solid and closer fitting when secured to the 3 electrode and pin, respectively, by the action of the dies.
It is understood that the ridge portion l8, shown in Figure 3, would, according to the modification shown in Figure '7, also be formed with its walls closely together, similarly to Ila.
The inside wall 38a and bottom Ifia in Figure '7, correspond to the Wall 38 and bottom H5 in Figure 1.
If desired, the up-shap mem er with the ridge port-ions IT and l-8 mayalso be obtainedfrom a solid blank B, as shown at lib and I8!) in Figure 8.
It is obvious that some changes-may be made in the form, construction and arrangement of the several parts, as shown, within the scope ofnthe shaped top, said cone-shaped bottom and coneshaped top being adapted to engage the cupshaped member within the bottoms of the respective ridges thereof, the outer sides of said ridges being pressed inward and over, respectively, the cone-shaped bottom of the electrode and the cone-shaped top of the pin, whereby to form a hole-proof and close fitting of said parts.
2. In a device, as claimed in claim 1, and wherein the inside diameterofthe inner ridge at the bottom of the cup-shaped member conforms in size to the diameter of the bottom edge of the cone-shaped bottom of the electrode, and the inside diameter of the outer ridge at the bottom of the cup-shaped member conforms in size t0 the diameter of the cone-shaped portion of the The following references are of record in the le. of, this p e UNITED STATES PATENTS Number me Date r 2,217,438 Francis 0on8, 194 0 2,360,701 MacFadden Oct. 17, 194 1,
