I have quite a few small servos at school (the small ones, like in the picture below). The problem is, teenagers are not very careful and when dismantling circuits we make in lessons they are pulling the cable rather than the black connector. This is resulting in many of the wires being pulled out of the black connector.
My question is, what are they called and is it easy for me to reconnect/crimp/ or attach them to new ones? They need to be female connectors as the boards they connect them to have pins.
