6、he following guide should be considered: 1. 2. 3. 4. 5. 6. An outline drawing should show all the dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged detail views may be used if necessar

7、y. The outline drawing should consist of three parts: 2.1 2.2 2.3 The A drawing with dimensional symbols (capital letters) as shown in figure 1 below and applicable notes, if necessary. A tabular listing relating the drawing symbols to the actual dimensions. Where possible this should be shown on th

8、e same page as the drawing. An “actual-size sketch. outline drawings should be executed in the 3rd angle projection. The function and the identification of the lead connections (terminations) should be deter- mined by agreement between the supplier and the user. It should not be defined on the outli

Pour les sorties (bornes) comportant une dcoupe, fournir seulement les valeurs mini- males des dimensions U et W. 7. 8. 9. 10 Outline dimensions A, B

12、, C, D and E should be listed with maximum values only. Lead (termination) cross-sectional dimen- sions should be listed with minimum and maximum values. If applicable, nominal dimensions may be added. The spacing of the leads (terminations) - H - should be listed with minimum, nominal and maximum d
