Thanks. I notice the same thing in other devices as well. Why isn't there one at the end close to the computer?

Hi, My camera USB cable has this cylindrical container close to the end where the USB connects to the camera. When I opened it up, the cable was going through two holes in the metal. The metal wasn't perfectly black, and it wasn't smooth. What is that piece of metal for? I don't know much...
