CRT socket

A CRT socket, comprising:

• a ring-shaped portion;
• a cylindrical central hole passing through said ring-shaped portion from a front face to a rear face thereof;
• signal connecting means approximately concentrically located with, and on an outside of, said cylindrical central hole;
• said signal connecting means including means for engaging signal terminal pins of a CRT;
• a cover portion equipped with high voltage connecting means that is provided approximately concentrically with said cylindrical central hole and engages a focusing terminal pin of said CRT;
• a base portion corresponding to a rear face of said cover portion,
• a cover-side focusing terminal pin housing in said cover portion;
• a base-side focusing terminal pin housing in said base portion so as to engage said cover-side focusing terminal pin housing, said housing forming at least double insulating side walls that separate an end of said focusing terminal pin from the outside.

A CRT socket, comprising:

• a ring-shaped portion;
• a cylindrical central hole in said ring-shaped portion passing therethrough from a front face to a rear face thereof;
• signal connecting means disposed approximately concentrically with, and on an outside of, said cylindrical central hole;
• said signal connecting means including means for engaging signal terminal pins of a CRT;
• a cover portion;
• said cover portion including high voltage connecting means located approximately concentrically with said cylindrical central hole;
• said high voltage connecting means including means for engaging a focusing terminal pin of said CRT;
• a base portion corresponding to a rear face of said cover portion;
• and
• a base-side focusing terminal pin housing in said base portion forming a gap of at least 1.0 mm between an end of said focusing terminal pin and side walls and a bottom of said base-side focusing terminal pin housing.

A focusing terminal pin housing in a CRT socket comprising:

• a base portion;
• a cover portion;
• said cover portion including first and second focusing pin openings for insertion of CRT focusing pins therein;
• a first central wall dividing said base portion to separate regions for said first and second focusing pins;
• a second central wall corresponding to said first central wall;
• one of said first and second central walls being divided into first and second walls between said separate regions;
• and
• the other of said first and second walls including a member fitting into said first and second walls, whereby a double air barrier is formed between ends of said first and second focusing pins.
