27、 for connecting devices as separate entities with screwless-type clamping units 1 Scope This clause of Part 1 is applicable. Addition: This standard applies to connecting devices with screwless-type clamping units primarily suitable for connecting unprepared conductors. In this standard, screwless-t

28、ype terminals are referred to as terminals. NOTE This standard does not include insulation piercing connecting devices (IEC 60998-2-3), twist-on connecting devices (IEC 60998-2-4) and flat, quick-connect terminations (IEC 60998-2-5). 2 Normative references This clause of Part 1 is applicable. 3 Defi

29、nitions This clause of Part 1 is applicable except as follows: Addition: 3.101 screwless-type terminal terminal for the connection and subsequent disconnection of two or more conductors, the connection being made directly or indirectly by means of springs, wedges, or the like NOTE Examples of screwl

30、ess-type terminals are given in Figure 102. 3.101.1 universal terminal terminal for the connection and disconnection of all types of conductors (rigid and flexible) 3.101.2 non-universal terminal terminal for the connection and disconnection of a certain kind of conductor only (for example, solid co

35、inals classified according to 7.101.2 shall be marked as follows: with the letter(s) “s” or “sol” for terminals declared for solid conductors; with the letter “r” for terminals declared for rigid conductors; with the letter “f” for terminals declared for flexible conductors. This marking shall appea

36、r where it is practical on the end product or on the smallest package unit or in technical information and/or catalogues. 8.102 Addition: An appropriate marking indicating the length of insulation to be removed before insertion of the conductor into the terminal shall be shown on the product or on t

37、he smallest package unit or in technical information and/or catalogues. 9 Protection against electric shock This clause of Part 1 is applicable. 10 Connection of conductors This clause of Part 1 is applicable except as follows: Addition: 10.101 The connection or disconnection of conductors shall be

38、made either by the use of a general purpose tool or a convenient device integral with the terminal to open it and to assist the insertion or the withdrawal of the conductors (for example, for universal terminals); or by simple insertion. For the disconnection of the conductors an operation other tha

39、n a pull on the conductor only shall be necessary (for example, for push-wire terminals). 10.102 Terminals shall accept two or more conductors of the same or of different nominal cross-sectional areas or compositions if applicable. Universal terminals shall accept rigid (solid or stranded) and flexi

40、ble unprepared conductors. Non-universal terminals shall accept the types of conductors declared by the manufacturer. The relationship between the rated connecting capacity of clamping units and connectable conductors as well as data on diameters of conductors are given in Table 101. Page6 EN6099822

41、:2004069-89-22 IE:C2002 7 10.103 Each terminal shall accept conductors of cross-sectional areas and types as indicated in Table 101, for the relevant values of the rated connecting capacity. Terminals shall provide, in addition, appropriate connection of at least the two successive smaller cross- se

42、ctional areas, for example: a) a terminal having the rated connecting capacity of 1 mm shall clamp reliably a rigid and/or flexible conductor of 0,5 mm, 0,75 mm and 1 mm; b) a terminal having the rated connecting capacity of 10 mm shall clamp reliably rigid conductors of 4 mm, 6 mm and 10 mm and/or

43、flexible conductors of 4 mm and 6 mm. c) a terminal having the rated connecting capacity of 25 mm shall clamp reliably rigid conductors of 10 mm, 16 mm and 25 mm and/or flexible conductors of 6 mm, 10mm and 16 mm. d) a terminal for flexible conductors only and having a rated connecting capacity of 2

44、5 mm shall clamp reliably flexible conductors of 10 mm, 16 mm and 25 mm. (Exception: special types of terminals may accept a smaller range of cross-sectional areas as declared by the manufacturer.)
