2 Claims- (CI. 49-81) This is a division of my application, Serial No. 591,465, filed May 2, 1945, which issued September '7, 1948, as Patent No. 2,448,808.
This invention relates to a process of securing 2 to maintain both a mechanical and electrical connection between the contact I and rod 6.
A glass bead 1 is placed on the rod 6 with one end thereof in contact with the portion 3 of the a terminal or contact in the wall of a cathode- 5 terminal. ray tube or electron tube for making connection A hole or opening slightly larger than the bead from a source of electrical potential to an elec- I is provided in a wall 8 of the tube where the trode extending inside of said tube. contact is to be installed. The bead I and rod Heretofore, connections of this type have been 6 are placed in this hole with the disc portion made by fusing a portion of the glass wall of the 10 3 of the contact I in contact with the outer surtube and locating the terminal so that a lead face of the glass wall. The glass is then fused could be connected thereto. With such connecby applying heat to it and the corresponding tions the glass tube was in danger of being broken portion of t head 7 to fuse e Sam o ether as or cracked by the contact being struck or too shown in Fig. 3 and also to fuse the bead I more much pressure being applied thereto. Besides, rely on he r d 6, nd als fu e the lass since the contact surface between the contact o that it flo S y around the Portion 4 member and the wall of the tube was not much of e Contact as indicated a thus o e more than was provided by the thickness of the r ly anchoring the contact in the glass wall wall of the tube, the danger of leaking and and o decreasing the an er of a leakage path breaking the vacuum in the tube was increased. ming.
By the present invention prior difficulties have W at iS claimed is: been overcome and an electrical contact element The process of sealing a contact terminal to is Securely and firmly mounted on t t in the wall of an electron tube, which comprises Such way t t t danger of t t b b i forming a metal contact with a head and neck, broken by force applied to the contact or a blow said k t rm atin n an utwa dly xte striking and breaking it is minimized, and at portion having an wardly cur fi a the same time the danger of leakage of air ing an end of a meta r n Said neck, placing a through the part where the contact is installed glass ube o i r pl cin sai w rdly in the wall of the tube is materially decreased extending portion of said neck on the outside wall or entirely overcome, of said electron tube, fusing the wall of said The invention may be understood in connecelectron tube where said contact terminal is 10- tion with the accompanying drawing; in which: Gated, fusing t e W of sa ass tube to Said Fig 1 is m i of th t t; curved flange and fusing one end of said glass Fig. 2 is a side view partly in section showing e to the Wall of said electron tube. the contact and a pin therefor, which pin has a h process of sealing a contact terminal to short cylinder of glass thereon; and a wall of a glass tube, which consists in securing Fig 3 is t1 1 View showing portion a metal rod to said terminal, placing a glass bead of the wall of a tube with the contact in place. on Said p vi in a hole in the wall of said In the drawing, reference character I indicates tube, rting said rod and said glass bead into the rounded portion or head of a contact to which i hole, fusing Said glass h ad to said wall and connection is to be made f o a source of sa1d rod, and fusing said wall to a portion of said tential.
