QC/T 417-2001 consists of the following five parts under the general title Connector used in automobile wire harness and electrical device: ——Part 1: Definition, test method and requirement; ——Part 2: Type and dimension of the male terminal; ——Part 3: Type, dimension and special requirement of the ring terminal; ——Part 4: Type, dimension and special requirement of the device connector (male); ——Part 5: Type, dimension and special requirement of the device connector (female); This is Part 3 of QC/T 417-2001. This standard is developed 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 the revision of QCN 29010-1991 Type, dimension and technical requirements of low-voltage automotive ring terminals, QCn 29011-1991 Type, dimension and technical requirements of automotive ignition ring terminals and QCn 29013-1991 Type, dimension and technical requirements of automotive storage battery ring terminals. The following main changes are made with respect to QC 29010-1991, QCn29011-1991 and QCn 29013-1991: ——the original QCn 29010-1991, QCn 29011-1991 and QCn 29013-1991 are merged into one standard and renamed as Type, dimension and special requirement of the ring terminal. —— “3.2 Mark of ring terminal”, “3.3.2.1 Specification and dimension of direct fork head” and “3.3.3 Specification and dimensions of transverse fork ring terminal” in original QCn 29010-1991 are deleted. ——“3.2 Labeling example” in original QCn 29013-1991 is deleted. This standard is developed by reference to JIS D5403, DIN 72331, DIN 72332, DIN 72333 and ISO 3553. Attention is drawn to the possibility that no elements of this standard may be the subject of patent rights. This standard was proposed by and is under the jurisdiction of the National Technical Committee of Auto Standardization (SAC/TC 114). Connector used in automobile wire harness and electrical device Part 3: Type, dimension and special requirement of the ring terminal 1 Scope This standard specifies type, dimension and technical requirements of automotive ring terminal. This standard is applicable to connectors of low-voltage ring terminal, ignition ring terminal and storage battery ring terminal used in automobile wire harness and electrical device. 2 Normative references The following referenced documents are indispensable for the application of this standard.
