Overview and Principle of Voltage Drop Test System
Darui Electric recommends for you
I. Overview:
In this system, voltage drop and contact resistance are the electrical performance evaluation indicators for automotive wire harness connectors under high current and low current circuits; under constant current conditions, by testing the voltage drop in the wire crimping and terminal contact areas, contact resistance data can also be obtained; if the automotive connectors after simulated environmental testing are then subjected to voltage drop testing, the data can more truly reflect the characteristics of the product itself; it is suitable for scientific research institutes, enterprise R&D, incoming inspection, and quality centers to provide more and reliable data assurance.
II. Principle:
By using current, voltage, and time to detect the relationship between voltage drop, contact resistance, and temperature rise changes in wire harness connectors, it is the main electrical performance indicator for automotive connectors, which directly affects the signal transmission and electrical connection of various automotive electrical equipment, as well as the working stability and reliability of electrical equipment; poor contact resistance and voltage drop are the main causes of temperature rise during the operation of automotive connectors. Reducing contact resistance can effectively control temperature rise, thereby improving the life and performance of connectors.
