CONSTITUTION: A connector for electrical adapter includes a connector housing(102), a circuit coupler(104), a connection node(106), and a ground node(108). The circuit board(120) coupler is characterized as follows. The connector node is extended from inside of the circuit coupler and to outside of the circuit coupler so that the outer extension of the connector node is implemented on the line of the upper side of the connector housing. The ground node is extended to the outside of both side walls of the connector housing in order to align the upper side of the ground node extension to the outer extension of the connector node. A connector container(160) for the size of the connector housing is provided on the circuit board.
