According to a recent survey by the National Electrical Manufacturers Association, the most-used type of connector in the United States is the coaxial connector, which is used to connect television antennas to TVs. This is quite a funny fact to consider, as it means that the humble coaxial connector, which is often overlooked as an unexciting piece of hardware, is actually one of the most widely used types of connectors in the US.
