Title:Wiring Component Design Guidelines
Issuing Committee:
Scope:This document gives general guidelines to be used during the connector design stage. Various guidelines may not apply in all situations. Therefore, sound engineering judgment must be used in their application. Consider these guidelines as the basis for connector and wiring DFMEA’s. Items in this document are grouped by DFMEA functional requirements. Groups are as follows:A.Electrical ContinuityB.Electrical Isolation/SealingC.Device AssemblyD.Harness AssemblyE.Vehicle AssemblyF.MaterialsG.ServiceabilityH.Environmental RequirementsI.High Voltage (≥ 60V) Application RequirementsThis document gives general guidelines to be used during the connector design stage.
