Water stop structure for wire harness and wire harness
View Patent ↗A water stop structure for a wire harness includes a cylindrical shield shell which is disposed at an intermediate portion of a shield member in a longitudinal direction, an outer water stop mechanism which is disposed on a side of an outer peripheral surface of the cylindrical shield shell, and an inner water stop mechanism which is disposed on a side of an inner peripheral surface of the cylindrical shield shell. The inner water stop mechanism has an elastic water stop plug member. A shell-side seal portion which is in watertight contact with the inner peripheral surface of the cylindrical shield shell and one or plural conducting path-side seal portions which are in watertight contact with outer peripheral surfaces of covers of the conducting paths are formed on the water stop plug member.
1. A water stop structure for a wire harness comprising:
a cylindrical shield shell which is disposed at an intermediate portion of a shield member in a longitudinal direction, the shield member covering one or plural conducting paths, and which is made of an electrically conductive metal;
an outer water stop mechanism which is disposed on a side of an outer peripheral surface of the cylindrical shield shell; and
an inner water stop mechanism which is disposed on a side of an inner peripheral surface of the cylindrical shield shell,
wherein the inner water stop mechanism has an elastic water stop plug member; and
wherein a shell-side seal portion which is in watertight contact with the inner peripheral surface of the cylindrical shield shell and one or plural conducting path-side seal portions which are in watertight contact with outer peripheral surfaces of covers of the conducting paths are formed on the water stop plug member, the one or plural conducting path-side seal portions being formed so as to pass through the water stop plug member.
2. The water stop structure for the wire harness according to claim 1 , wherein the inner water stop mechanism includes a slip-off preventing mechanism which prevents the water stop plug member from slipping off the cylindrical shield shell.
3. The water stop structure for the wire harness according to claim 1 , wherein the outer water stop mechanism includes a seal portion which is formed on the outer peripheral surface of the cylindrical shield shell and a grommet which is provided so as to be in watertight contact with the seal portion.
4. The water stop structure for the wire harness according to claim 1 , wherein the outer water stop mechanism includes a flange-like metal shell which is formed projectingly from the outer peripheral surface of the cylindrical shield shell and a seal member which is provided so as to be in watertight contact with the flange-like metal shell.
5. A wire harness wherein the water stop structure for the wire harness according to claim 1 is disposed in a penetration portion in a vehicle.
