Abstract
A cable harness includes a plurality of cables and an electrically-conductive outer conductor surrounding the plurality of cables. The outer conductor is partially constituted by a conductor tube having a smooth outer peripheral surface. An outside water cutoff member configured to prevent water from coming inside a hole of a body panel is placed between the smooth outer peripheral surface of the conductor tube and an edge of the hole of the body panel. Further, an inside water cutoff member having through holes through which the plurality of cables of the conductor tube passes, and configured to close an end of the conductor tube is provided.
Claims10
A water cutoff structure for a cable harness penetrating through a hole of a body panel, the cable harness includes a plurality of cables, and an electrically-conductive outer conductor provided so as to surround the plurality of cables, the electrically-conductive outer conductor being partially constituted by a conductor tube having a smooth outer peripheral surface,
- the water cutoff structure comprising:
- an outside water cutoff member placed between the smooth outer peripheral surface of the conductor tube and an edge of the hole of the body panel, the outside water cutoff member being configured to prevent water from passing outside of the conductor tube through the hole of the body panel;
- an inside water cutoff member configured to prevent water from passing through the inside of the conductor tube, the inside water cutoff member including a stopper portion and a covering portion, the stopper portion is provided so as to penetrate into the conductor tube and to make close contact with a whole circumference of an inner peripheral surface of the conductor tube, and the covering portion surrounds an end of the conductor tube on an outside of the conductor tube;
- and
- a fastening band placed around an outside of the covering portion to fasten the covering portion to the conductor tube.
A cable harness comprising:
- a plurality of cables;
- an electrically-conductive outer conductor partially constituted by a conductor tube having a smooth outer peripheral surface, and provided so as to surround the plurality of cables;
- an inside water cutoff member configured to prevent water from passing through the inside of the conductor tube, the inside water cutoff member including a stopper portion and a covering portion, the stopper portion is provided so as to penetrate into the conductor tube and to make close contact with a whole circumference of an inner peripheral surface of the conductor tube, and the covering portion surrounds an end of the conductor tube on an outside of the conductor tube;
- and
- a fastening band placed around an outside of the covering portion to fasten the covering portion to the conductor tube, wherein:
- the smooth outer peripheral surface of the conductor tube receives an outside water cutoff member configured to prevent water from passing between the cable harness and an edge of that hole of a body panel through which the cable harness penetrates.
