PURPOSE: To allow an easy sealing work and provide a waterproofing function by bending a projection piece formed on the opening edge of a connection piece hole, and sealing a gap among the projection piece, the opening edge and a connecting piece. CONSTITUTION: An inner connecting piece 21 is inserted in the connecting piece hole 11 of a housing 2. In this case, the piece 21 is inserted with the holding section thereof guided along a retaining groove 29 formed on one of the inner sides of the hole 11. Also, the piece 21 is properly retained with a tooth section 26 forcibly pressed into and coupled to the groove 29. Then, the projection piece 12 of the housing 2 is bent downward to roughly close the rear opening of the hole 11. In this case, only an extremely small gap is left among the bent projection piece 12, the edge of the hole 11 and the piece 21 in the groove 29. On the other hand, the cylindrical section 8 of an outer conductor 7 is coupled to the columnar section 6 of the housing 2 and, then, the conductor 7 is bent at the notch section thereof. Furthermore, a projection 20A formed at the notch section due to bending, and a recess 20B are firmly fitted to each other. Thereafter, a seal coat is applied along the direction of the connecting section 21A of the piece 21, or via a hole formed on the rear end of the outer conductor 7. |
