Connectors

Electrical Connection standards for road vehicles focus on the dimensional characteristics of both on-board and towing electrical connectors. Also addressed in some standards are electrical characteristics, contact allocation, performance requirements, tests, and test requirements. Additionally, the interchange of digital information is covered by the ISO 11992 as it uses the electrical towing connections. These standards are related to the electrical connections within a motor vehicle.

SAE J 1742-2010 (SAE J1742-2010)

Connections for High Voltage On-Board Road Vehicle Electrical Wiring Harnesses~Test Methods and General Performance Requirements

Procedures included within this specification are intended to cover performance testing at all phases of development, production, and field analysis of electrical terminals, connectors, and components that constitute the electrical connection systems in high power road vehicle applications That operates at either 20 V to 600 volts regardless of the current applied or any current greater than or equal to 80 A regardless of the voltage applied. These procedures are applicable only to terminals used for In-Line, Header, and Device Connectors and for cable sizes up to 120 mm/u2 (4/0). In cases where power levels are mixed in the same connector, (i.e. sensing or normal 14.5 volt system circuits with High Power Contacts) the High Power Contacts must pass J1742 requirements, and all other contacts must pass SAE J2223-2 requirements. The connection system (housing and high power contacts) shall meet J1742 requirements. The requirements and procedures in this document are not intended for connections internal to electrical/electronic modules or complete subassemblies. This document does not contain a test for EMI/EMC since these parameters must be tested as a combination of cable and connector. These are considered system level requirements. Determination of the need and type of test must be considered at that level.
