What is the development trend of electrical terminal connectors really used in aerospace?

Before answering this question, we should first look at the 53rd Paris air show on June 17-23, 2019. This exhibition is not popular here. Anyway, you know it is the most famous air show in the world, or @ their official microblog in China. Several of the world leaders in the aviation industry went to the exhibition hand in hand anyway, and set up a stall, where they put out their treasures.

The exhibition highlights two major trends: connectivity and electrification (large scale electrification is still a distant goal in the West). The original text is connectivity and electrification. It is mainly reflected in enhancing the navigation, power management, controllability and comfort of aircraft by airborne electronic equipment. At the same time, it also opens the prelude to the next flying era: hybrid aircraft and electric aircraft.
