The invention discloses a plate-to-plate intensive assemblage coaxial connector, comprising two sockets and a commutator. A first flange and a second flange with different axial lengths are arranged on the peripheral planes of the two ends of the commutator; a groove is arranged on the side wall at the bottom of the opening of the socket; when the commutator is inserted into the socket, the first flange is located in the groove, the second flange clings to the inner side wall of the corresponding socket opening. Because the first flange, the second flange and the groove matching the first flange are provided, the plugging and pulling forces become varied, the commutator is left on one of the circuit boards when being pulled away, thereby, the operation time is saved and ineffective plugging and pulling actions reduced; in addition, the lockup between the shells is used to largely increase the plugging and adapting frequency. By taking advantage of the clearance between the commutator shell and the insulator thereof, the commutator deviates in the opening upon incorrect medium condition, as a result, the position is corrected automatically and the purpose of direct plugging and adapting is achieved.
