30、ples and submultiples of the SI units. 2.2 Terminology The terminology used in and applicable to this specification is included in IEC 50 (581). IEC 512 and EN2591 also contain applicable terms. For the purpose of this specification, the following additional terms and definitions shall apply: 2.2.1
31、hybrid connectors Detailed specifications in accordance with this Sectional Specification which contain integrated hybrid elements from other Sectional Specifications in the CECC system shall be permitted providing that : a) The hybridising elements are assessed using the appropriate test method fro

33、 2.2.2 group of related connectors A group of connectors within a sub-family having common features. Typical examples: same mounting and coupling features but different kinds and numbers of contacts, different inserts and types of shells. A group of related connectors is covered by a single DS. 1) I

35、range such as fixed, free, coupler or adaptor, connectors mounting features, etc. 2.2.6 variant Variations within a type and style or within a group of related connectors. 2.2.7 Examples 2.3 Classification into climatic categories The connectors are classified into climatic categories in accordance
36、with the general rules given in IEC 68-1. The following preferred temperature ranges and severities of the damp heat steady state tests have been selected. 2.4 Creepage and clearance distances Permissible operating voltages depend on the application and on the applicable or specified safety requirem

44、ons and in the order given: NOTEThe number of characters shall not exceed 18 including spaces. 1) CECC abbreviated to “C”; 2) An abbreviated reference of this sectional specification to “752” followed by the number of the Detail Specification eg. 800 for a Committee Detail Specification or 001 for a
45、 Manufacturers Detail Specification; 3) A letter denoting the style of the connector. (The system shall be prescribed in the Detail Specification.) 4) A letter denoting a housing (shell) or body size; 5) two numbers denoting the contact arrangement. (Not necessarily the number of contacts); 6) A let
46、ter denoting the type of contact. The following letters shall be used. M = male contact F = female contact H = hermaphroditic contact 7) A letter denoting the basic type of the terminations. The following letters shall be used: E = solder termination, eyelet S = solder termination, solder bucket F =
47、 solder termination, printed wires C = crimp W = wrap termination D = insulation displacement P = press-in 8) A letter or digit denoting polarization or orientation by a particular arrangement of keys and keyways on housing (shells) or bodies, or position of insert in housing such as N, A, C, D, W,
48、X, Y, Z or 0, 1, 2, etc., where N and 0 are the neutral 2)position. 9) A digit to denote variations permitted by the Detail Specification. For example: plating, performance, colour, etc.; 10) If prescribed in the Detail Specification, the type designation may optionally be extended to include an additional block to cover further information such as climatic category, termination information, etc. (See CECC 75 201); 2) Neutral position is the normal or standard position.
