Product Code:SAE J1742
Title:Connections for High Voltage On-Board Road Vehicle Electrical Wiring Harnesses-Test Methods and General Performance Requirements
Issuing Committee:Electrical Distribution Systems Steering Committee
Scope:This SAE REcommended practice defines recommended test methods and general performance requirements of single-pole and multi-pole connectors for on-board electrical wiring harnesses of electric or hybrid powered road vehicles operating at voltages between 50 and 600 V AC or DC rms and those circuits using copper wire only.these requireemnts are not intended for connections internal to electrical/electronic modules or complete subassemblies.this document applies to connectors designed to be disconnected in the case of repair and/or maintenance after mounting in the vehicle.This document excludes onoe-part connections, i.e., where one part of the connection has direct contact to the pattern of the circuit board.Duty cycles are considered to be application specific and are not specified in this document; however, these effects must be considered during design.The Recommended Practice for Highvoltage Wiring Assembly is contained in SAE j1673. The Recommended practice for Low Voltage Connector Performance is contained in SAE J2223 (Parts 1, 2, 3, and 4).【英文标准名称】:StandardSpecificationforAluminumDiffusionCoatingAppliedbyPackCementationProcess
