Foreword

QC/T 417-2001 "Connectors for Automobile Wiring Harness and Electrical Equipment" consists of five parts.

- Part 1: Definitions, test methods and general performance requirements (the automobile part);

- Part 2: Test methods and general performance requirements (motorcycle part);

- Part 3: Taps for single-pole connections- Dimensions and specific requirements;

- Part 4: Tabs for multi-pole connections- Dimensions and specific requirements;

- Part 5: Column tabs for single- and multi-pole connections - Dimensions and specific requirements. This standard is the part 3 of QC/T 417-2001.

This standard was drafted in accordance with the rules given in GB/T 1.1-2009 Directives for standardization - Part 1: Structure and drafting of standards.

This standard is a revision of QCn 29010-1991 "Type, size and technical requirements for automobile low-voltage wire terminal", QCn 29011-1991 "Types, size and technical requirements for ignition wires and connectors for automobiles", QCn 29013-1991 "Type, size and technical requirements for automotive battery cables and connectors". As compared with QCn 29010-1991, QCn 29011-1991, QCn 29013-1991, the main changes are as follows.

- COMBINE the original QC/T 29010-1991, QC/T 29011-1991, QC/T 29013-1991 into one standard. CHANGE the standard name into "Type, dimension and special requirement of the ring terminal".

- DELETE the "3.2 Marking of wire connector", "3.3.2.1 Specifications and size of the fork-shaped straight connector", "3.3.3 Specifications and size of the transverse fork-shaped wire connector" in the original QCn 29010-1991;

- DELETE the "3.2 Example of marking" from the original QCn 29013-1991.

This standard refers to and adopts JIS D5403, DIN 72331, DIN 72332, DIN 72333, ISO 3553. This standard does not involve patents.
