Technical Parameters
1) Contact resistance between contacts: under normal ambient conditions, the contact resistance between contacts ≤7 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤3 mΩ And after inserting the connection cord (or test cord) into the module for 200 times, the increasing resistance ≤3 mΩ
2) Contact resistance between conductor and contact: under normal ambient conditions, the contact resistance between contacts ≤3 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤2 mΩ. And after terminating for 200 times, the increasing resistance ≤2 mΩ.
3) Dielectric strength: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts is able to withstand an AC voltage of of 1000V (virtual value) at 45Hz~60Hz sinowave for 1 minute, without spark over and flying arc
4) Gas tight performance: contact touches the conductor at both sides, and thus forming the gas tight area, while the area of gas tight occupies ≥50% of the touched area on each side.
