An electrical-conductive assembly for a signal cable. The signal cable includes an outer insulation cover and a plurality of cores inside the outer insulation cover. Each core has a protective sheath and an electric wire located in the protective sheath. The electrical-conductive assembly includes an electrical-conductive portion and an electrical-conductive portion member. The electrical-conductive portion is provided on a section of the signal cable with a portion of the outer insulation cover removed. Each core inside the electrical-conductive portion is formed with a naked lead section by removing a portion of the protective sheath. The electrical-conductive member is assembled with the electrical-conductive portion and includes at least one electrical-conductive covering piece electrically connected to the naked lead section and at least one electrical-conductive post extending from the electrical-conductive covering piece.
