It is connected by pushing it into the slit, and by connecting both connector halves, both terminals are connected and conduction between both core wires is taken, but at this time, one of the core wires is connected to the terminal at the intermediate part. By connecting and connecting the other end to a terminal and taking out one side portion of the one core wire from the gap between both lid members, the other core wire is multi-connected to the one core wire. Become. Therefore, each core wire is pushed into the U-slit of the terminal and is reliably connected, and the long-term reliability of the connection is improved. Also, in the case of multi-connection of a multi-pair cable, a predetermined number of terminals are arranged in parallel on both connector halves, and the cores are connected to the respective terminals in the same manner as described above, and the connector halves are fitted to each other. Since conduction can be achieved, the connection portion is compact and the connection form is in a parallel state. Furthermore, by covering the cover on the upper surface of the cover member of the connector half while guiding the core wire taken out from the gap of the cover member to the outside by the groove portion, it is possible to prevent intrusion of unnecessary objects from the outside into the gap, so that connection is made.
