PROBLEM TO BE SOLVED: To solve a problem associated with a connecting cable for connection with a main unit installed outdoor that, since the connection box on the building side is exposed to the outside-air, moisture enters the interior of the cable through the connecting portion of the cable and may cause a fault in the outdoor main unit. SOLUTION: To fill the gap between the cable cores and the cable covering of a cable connection, the cable cores are threaded through the through holes in a sealing portion, and the sealing portion and the end of the cable covering are covered with a cap. Adhesive is used as required, and the cap is tightened with a tightening tool. |
