Telecommunication main distribution frame structure including a PC board, several pairs of insertion pins, four insertion seats, four buses, four corresponding insertion seats connected with one end of the buses and four connectors connected with the other end of the buses. The PC board is formed with several insertion holes and soldering holes electrically connected with each other. The insertion seats are soldered at the soldering holes of the PC board. The corresponding insertion seats are inserted in the insertion seats. The PC board has a left board, a middle board and a right boards integrally connected with each other. Each of two openings of the insertion hole is provided with a circle of shallow conductive face divided-by a locating split into a left and a right halves. Each of two openings of the soldering hole is provided with a shallow conductive face. The insertion pin is a rectangular column made of insulating material. Each of two ends thereof is formed with a lip and a resilient well conductive plate is connected between the lips. The insertion pins are inserted into the insertion holes with the conductive plate aimed at the locating split of the insertion hole, whereby the conductive plate is resiliently pressed to contact with the conductive faces of the insertion hole so as to electrically connect the conductive faces.
