PURPOSE: An underground transmission wire connector is provided to facilitate the connection and separation between an outlet and a plug by using elastic motion of a protrusion bar of a separation preventing unit. CONSTITUTION: A plug is inserted into a plug mounting groove of an outlet, and connects a jack connection part of a conductive member to a jack unit of a first conductive material. The outlet forms the electric connection between power transmission lines through the connection of the plug. When the plug is inserted into the plug mounting groove of the outlet, a protrusion bar(226) of the separation preventing unit is moved along a separation preventing guide groove(114). Through the fixture of the protrusion bar, a plug body is prevented from being separated from the outlet.
