Abstract
A CRT socket has reduced thickness but maintains favorable insulation without requiring a change in the construction of the neck of a CRT. The CRT socket arrays a plurality of signal and focusing contact sockets about a central hole. The ends of signal pins of a CRT and of the focusing contact sockets passing partly through an enlarged hole in a circuit board, whereby the height of the CRT socket is reduced.
Claims5
A slimline CRT socket, comprising:
- a ring-shaped portion having a cylindrical central hole passing therethrough from a front face to a rear face thereof;
- a plurality of concave signal contact housings in a rear face of said ring-shaped portion at positions that are concentric with said cylindrical central hole;
- signal contacts, each in a different one of said signal contact housings;
- signal contact holes provided on a front face of said ring-shaped portion to allow signal terminal pins of a CRT to be inserted into the corresponding signal contact housings thereby to permit connection of said signal terminal pins to said signal contacts;
- a cover portion;
- said cover portion having a concave focus contact housing in a rear face thereof;
- a focus contact in said focus contact housing;
- a focus contact hole in said focus contact housing;
- said focus contact hole allowing a focusing terminal pin of said CRT to be inserted so that said focusing terminal pin is connected to said focus contact;
- a base portion corresponding to said rear face of said cover portion;
- a concave focusing terminal pin housing that houses said focusing terminal pin on said base portion;
- and
- said focusing terminal pin housing passing through a surface of a board that is attached to said CRT socket and projecting outward from an opposite surface thereof.
10 more elements
A CRT socket for attachment to a circuit board, comprising:
- signal terminals fittable to said circuit board for connection to external circuits;
- signal contacts for receiving signal pins of a CRT;
- a focusing terminal pin housing passing through one surface of said circuit board and passing beyond an opposite surface thereof;
- and
- means in said focusing terminal pin housing for permitting connection of a focusing terminal pin thereto, whereby a height of said CRT socket is reduced.
2 more elements
A CRT socket comprising:
- a plurality of signal pin contacts surrounding a first opening in said socket;
- at least one a focusing terminal pin socket adjacent said first opening;
- ends of CRT signal pins, when installed, passing at least partly through a second opening in a circuit board to which said CRT socket is mounted;
- and
- said at least one focusing terminal pin socket passing at least partly through said second opening, whereby a height of said CRT socket above a surface of said circuit board is reduced.
