I'm designing a schematic overview for a client and need to show that a microphone cable is plugged into a video camera. No problem to represent the video camera just as a little box, and the mic with another, even small box. The cable is just represented with a straight line -- but to show that it must be connected is tricky for me, as someone without a background in this sort of stuff.
Suggestions on how to communicate that would be very appreciated! Thanks a lot.
