National Standard of the People's Republic of China Preparation of outline drawings of cathode-ray tubes GB11485-89 Reduced to SJ/T11081-96 This standard adopts the international standard 1EC139--(1962) "Drawing of outline drawings of oscilloscopes and picture tubes". 1 Subject content and scope of application This standard specifies the rules for drawing outline drawings of cathode-ray tubes. This standard is applicable to the drawing of outline drawings of cathode-ray tubes. 2 Table of outline dimensions of cathode-ray tubes If the dimensions listed in the table are applicable to the cathode-ray tube being drawn, these dimensions should be given in the outline drawing. In the following tables, "\nominal" indicates nominal values and tolerances. Code Required view Required size Length from panel center to line joining cone and straight neck Length from reference line to panel center Neck outer diameter Radius or dimension necessary to determine sidewall shape Panel outer diameter, with two or more radii when shape requires Maximum panel diameter Maximum panel diagonal Maximum panel length Maximum panel width Radius necessary to determine edge and corner shape of panel end face (top view) Screen diagonal or diameter Screen Maximum length Circular tube Electrostatic deflection and Electrostatic focusing Side view Nominal ± Nominal soil Nominal ± Approved by the Ministry of Machinery and Electronics Industry of the People's Republic of China in 1989-0321TTTKKAca Magnetic deflection and magnetic or electrostatic focusing Side view\ Nominal ± Nominal ± Nominal ± Rectangular tube Electrostatic deflection and Electrostatic focusing Nominal ± Nominal soil| |tt||Nominal size Nominal size Nominal size Magnetic deflection and magnetic or electrostatic focus Nominal size Nominal size Nominal size 1990-03-01 implementation Required dimensions Maximum width of screen Radius of curved edge and corner of screen Diameter or diagonal deflection angle\ Horizontal deflection angle" Vertical deflection angle) Position of side electrode cap and side lead-out needle GB114 85—89 Circular tube Electrostatic deflection and Electrostatic focusing Position of the outer conductive layer of the tube shell relative to the reference line or the position of the contact surface of the outer conductive layer relative to the reference line\) Predetermined position of the deflection coil and focusing element relative to the reference line Predetermined position of the ion trap magnet and (or) correction or alignment magnet relative to the reference line Position of the deflection center relative to the reference line Identification of the tube base\ Identification of the side electrode cap* Identification of the reference line gauge) Position of the tube neck axis relative to the center of the panel Projected length of the side lead-out needle Side lead Pin diameter Scale or external marking size Scale center relative to panel center and scale axis relative to panel axis orientation Protective coating relative to the protected part Size and orientation Required size or radius to determine the shape of explosion-proof device or mounting frame Frame fixed ear hole size Panel reference point relative to panel center Radial distance between fixed ear hole centers Axial position of fixed ear hole relative to panel reference point Interaxial position of explosion-proof device or mounting frame relative to panel reference point Displacement of any fixed ear and the plane passing through the other three fixed ears Magnetic deviation Rotation and magnetic or electrostatic focusing nominal g rectangular tube electrostatic deflection and electrostatic focusing see GB787 "tube base dimensions" see GB3189 "tube lead cap connection dimensions" see GB11484 "cathode ray tube reference line gauge dimensions" maximum nominal g nominal g nominal g nominal g nominal g or nominal nominal g nominal g nominal g YYKAONYKAa nominal g| |tt||Nominal soil Nominal size or nominal Nominal size Nominal size Nominal size Nominal size Nominal size Nominal size Nominal soil or nominal Nominal size Nominal size Nominal size Magnetic deflection and magnetic or electrostatic focusingbzxz.net Nominal size Nominal size Nominal size or nominal Nominal size Nominal size Required size The distance between the center of the grid plane and the reference line, the length of the flexible wire from the side wall The diameter of the flexible wire Axial deviation of the tube base to the tube neck axis GB11485-89 Circular tube Electrostatic deflection and Electrostatic focusing Nominal± Magnetic deflection and magnetic or electrostatic focusing Nominal± Rectangular tube Electrostatic deflection and Electrostatic focusing Nominal± Note: 1) Usually only the side view of the cathode ray tube is required, but the front view may also be required for some tube types, such as projection picture tubes.

Mark the distance from the center of the panel (nominal ±) b. Indicate the angular deviation that the plane through the side electrode panel and the tube axis can deviate from the beam track produced by a specified pair of deflection electrodes, or from the plane through a specified tube pin, C. Indicate on which side of the cathode ray tube the side electrode cap is located relative to the specified tube pin. 6) Specify the position of the side electrode cap by the following method: a. Mark the distance from the reference line (nominal ±); b. Indicate the angular deviation of the plane passing through the side electrode cap and the tube axis from the plane passing through the tube axis and the specified tube pin (or empty pin position): °C.Indicates on which side of the cathode ray tube the side electrode cap is located relative to the specified pin (or empty pin position). 7) Specifies the minimum size of the orientation and contact surface relative to the side electrode cap. 8) When the required type and data are not given in GB787, GB3189, GB11484 standards, the corresponding dimensions should be marked with reference to these standards. 9) The axis of the tube neck is specified as the line passing through the centers of the two specified planes of the tube neck. 10) It is required to specify the orientation of the scale axis relative to the deflection axis. 11) The center of the mounting bolt should be located at the four vertices of the rectangle formed by the two radial distance heights, and the bolt of the specified diameter should be able to pass through the fixing ear hole. 3 Legend The code on the figure refers to the dimension Note: The plane passing through the tube axis and the pin (or empty pin position) and the plane passing through the tube axis and the side electrode cap (on the side of the pin or empty pin position) can deviate from the beam trace generated by the specified pair of deflection electrodes by an angle tolerance of ±.
