CONSTITUTION:When a cable core wire (a) is inserted between a screw 90 of a core wire separating and transporting system (b) and a moving guide 91 at the time of connector fitting, the core wire a is led to the rotating screw 90 and untwisted and separated. Then, the coating color of every one core unit of the core wire a is detected by a non contact color sensor 5 and the resulting data is processed by a computer and the core wire units are so moved as to be positioned under a press-contact head 61 of a fastening system 6 from the first core wire unit. A prescribed contactor of a connector main body (c) is so moved one core by one core as to go under the press- contact head 61 and pressing the head 61 and cutting excessive core wire are carried out and these processes are repeated for the whole length of the core wire and a connector cover c1 is inserted in and united with the main body c. Consequently, the core wire connection work is carried out automatically and the workability is improved.
