For connectors between high-speed rail carriages, which type should be selected if the plugging frequency is low but the service life requirement is high?

A: GX series aviation connectors are recommended, with a plugging life of ≥10,000 times, which is far higher than the annual plugging demand of less than 10 times between carriages. At the same time, they can withstand a temperature range of -55~125℃, adapting to the extreme temperature difference of high-speed rail across regions. The contact resistance is <5mΩ, ensuring long-term stable transmission.
