Electrical lead-in tubular socket member for electronic tubes

Claim 2

An electrical lead-in apparatus for a cathode ray tube comprising: an envelope adapted to be hermetically sealed and having a wall portion of insulating material provided with an aperture therethrough; an electrical lead-in connector mounted within said aperture, having a closed end portion within said envelope spaced inwardly from said wall portion, an open end portion which opens to the exterior of the envelope, and a tubular side portion extending between said closed end portion and said open end portion to provide a pin receiving chamber within said connector whose length is greater than its maximum cross sectional width and which extends completely through the envelope wall and into the interior of the envelope; and seal means for attaching said connector to the envelope wall portion by a hermetic seal between said side portion of said chamber and said wall portion of said envelope.

Claim 3

An apparatus in accordance with claim 1 in which the connector has a lead attachment projection of solid metal extending from said closed end portion of a distance greater than the thickness of said side portion and positioned within said envelope so as to enable an electrical lead to be fused thereto without forming a hole through the conductor wall.

Claim 4

An apparatus in accordance with claim 1 in which the pin receiving chamber is of a uniform cross section throughout the length of said chamber, said chamber having a length greater than the thickness of said envelope wall and many times greater than the maximum cross Sectional width of said chamber.

Claim 5

An apparatus in accordance with claim 1 in which an electrical conductor pin of greater length than diameter is inserted into the chamber of said connector for electrical connection thereto, said pin extending from the exterior into the interior of the envelope.

Claim 6

An apparatus in accordance with claim 4 in which the conductor pin is a resilient member.

Claim 7

An apparatus in accordance with claim 5 in which the resilient pin member includes spring contacts.

Claim 8

An apparatus in accordance with claim 1 in which the envelope wall portion is made of glass, the connector is made of metal, and the seal means forms a glass-to-metal seal.

Claim 9

An apparatus in accordance with claim 1 in which the envelope wall portion is made of crystalline ceramic material, the connector is made of metal, and the seal means forms a ceramic-to-metal seal.

Claim 10

A device in accordance with claim 1 in which the open end portion of said connector is provided with an inwardly tapering inlet opening communicating with said chamber.

Claim 11

A device in accordance with claim 9 in which the connector side wall portion in the region of the seal is provided with a tapered outer flange at said open end portion.

Claim 12

A device in accordance with claim 10 in which the connector is a cylindrical tube and the inlet opening and flange are conical.

Claim 13

A device in accordance with claim 2 in which the lead attachment portion projects from the bottom of the closed end portion and is of reduced cross-sectional area.

Claim 14

A device in accordance with claim 1 in which the pin receiving chamber is cylindrical with a substantially uniform diameter throughout its length.

Claim 15

A device in accordance with claim 1 in which a tubular insert having spring contacts therein is attached within the connector.

Claim 16

A device in accordance with claim 2 in which the envelope is part of an electron tube which has a plurality of said connectors attached thereto with the closed end portions connected to electrodes within said tube.

Claim 17

A device in accordance with claim 15 in which the electron tube is a cathode ray tube and at least some of the connectors are connected to electron beam deflection plates within said tube.

Claim 18

An electrical lead in apparatus for a cathode ray tube, comprising: an envelope adapted to be hermetically sealed and having a wall portion provided with an aperture therethrough; an electrical lead-in connector disposed within said aperture and having a closed-end portion and an open-end portion, said closed-end portion being within said envelope and a tubular portion extending between said closed-end portion and said open-end portion to provide a pin receiving chamber within said connector whose length is greater than its maximum cross-sectional width and which is adapted to electrically receive a connector pin therein; and seal means surrounding said tubular portion from adjacent said open end portion to a position on said tubular portion substantially intermediate said open end portion and said closed-end portion for hermetically securing said connector in said aperture in electrically-insulated relationship with an inner surface of said envelope and with said open end portion in communication with the exterior of said envelope.

Claim 19

An electrical lead in apparatus for a cathode ray tube, comprising: an envelope adapted to be hermetically sealed and having a wall portion provided with an aperture therethrough; an electrical lead-in connector disposed within said aperture and having a closed-end portion and an open-end portion, said closed-end portion being within said envelope and a tubular portion extending between said closed-end portion and said open-end portion to provide a pin receiving chamber within said connector whose length is greater than its maximum cross-sectional width and which is adapted to electrically receive a connector pin therein; and seal means surrounding said tubular portion from adjacent said open end portion to a position on said tubular portion substantially intermediate said open end portion and said closed-end portion for hermetically securing said connector in said aperture in electrically-insulated relationship with an inner surface of said envelope and with said open end portion in communication with the exterior of said envelope.
