Analysis of Current-Carrying Capacity Test for Automotive Connector Terminals
Abstract
This work targets automotive connector developers and test engineers. Based on GWM3191 specification, it describes the test principle and operating steps for terminal ampacity measurement. This paper also covers sample related requirements as well as processing and
fitting of measured data, and concludes a practical test approach for evaluating terminal current carrying performance.
