LX-9831Voltage drop testing system
1、 Overview:
The voltage drop and contact resistance of this system are electrical performance evaluation indicators for automotive wire harness connectors in high current and low current circuits; Under constant current conditions, contact resistance data can also be obtained by testing the voltage drop in the wire crimping and terminal contact areas; If the voltage drop test is conducted on the automotive plug after simulating the environment test, the data can more accurately reflect the characteristics of the product itself; Suitable for providing more reliable data assurance to technical departments such as research institutes, enterprise R&D, incoming inspection, and quality centers.
2、 Principle:
Detecting the relationship between voltage drop, contact resistance, and temperature rise of wire harness connectors through current, voltage, and time is the main electrical performance indicator of automotive connectors. It directly affects the signal transmission and electrical connection of various electrical equipment in the car, as well as the stability and reliability of electrical equipment operation; Poor contact resistance and voltage drop are the main causes of temperature rise in automotive connectors during operation. Reducing contact resistance can effectively control temperature rise, thereby improving the lifespan and performance of connectors.
3、 Scope of application:
Widely used for measuring contact resistance, temperature rise, voltage drop, or load of wire harnesses, connectors, switch contacts, relays, automotive switches, and non rewirable plug pins and connection plug leads and similar wiring outlets. It is also suitable for use in products with similar characteristics; Connected with internationally recognized measurement methods.
4、 Meet the standards:
Meet the requirements and testing specifications of national standards and European and American standards:QC/T730 ; ISO 6722：two thousand and twoGB/T 2951; GB/T 3048；QC/T29106; QC/T413 .
