PC Cords The purpose of sync cords is to allow the camera to control the flash, so the flash fires at the correct time. Other common names for electrical cords to connect flash to camera are PC cord, sync cord and synch cord.
PC Cord Before the days of hotshoe flash connectors and TTL flashes, the method of connecting the flash to the camera body was by PC cord. This cord if fairly thin and can be easily broken but can fire a flash from a great distance if necessary.

The cable that attaches to the PC terminal is called a sync cord (for synchronization and pronounced "sink") or PC cord. When you take a picture, a signal is sent from the camera along the cable to fire the studio flash.

If you have such a camera you could cover up the contacts with electrical tape or use a PC cord adapter so the flash unit doesn't plug directly into the camera's hotshoe mount at all.
It has an electrical contact that aligns with the contact on the flash unit's "foot" and fires the flash when you press the shutter release. This direct flash-to-camera contact eliminates the need for a PC cord.
