A watertight junction box includes a box body, a lower floating plate, an upper floating plate, a lock cap, a modular cable inserted into the box body and kept in contact with sharp copper contacts, a holding down plate for holding down an external power wire on the upper floating plate to cause electric contact between the external power wire and the sharp copper contacts, and a predetermined amount of silicon rubber filled in between the lower and upper floating plate that is deformed to wrap about the connection area between the sharp copper contacts and the external power wire when the lock cap is tightly fastened to the box body to force down the holding down plate.
