Abstract

A connecting end portion of a shield pipe with respect to a shield member is waterproofed. A shield conduction path includes: a shield pipe having a connecting end portion opened obliquely downward; a braided wire fasten to an outer periphery of the portion by a swaging ring; a plurality of wires inserted into the pipe and braided wire; a rubber shield grommet and surrounding a fastening region between the braided wire and swaging ring; a binding band that fixes an upper end portion of the grommet to an outer periphery of the pipe in a liquid tight manner; a tube formed of synthetic resin surrounding the braided wire and having an upper end portion surrounding a lower end of the grommet; and exterior adhesive tape wound in a liquid tight manner from an outer periphery of the upper end portion of the tube over an outer periphery of the grommet.

First claim

The invention claimed is:

1. A shield conduction path comprising:
a shield pipe having one end portion formed as a connecting end portion, the connecting end portion being opened obliquely downward;
a shield member having a cylindrical shape and flexibility, the shield member being fasten to an outer periphery of the connecting end portion in a conductive manner by a swaging ring;
a plurality of wires inserted into the shield pipe and the shield member;
a shield grommet formed of rubber, the shield grommet being arranged so as to surround at least a fastening region between the shield member and the swaging ring;
a fixing member that fixes an upper end portion of the shield grommet to an outer periphery of the shield pipe in a liquid tight manner;
a tube having flexibility and formed of synthetic resin, the tube surrounding the shield member and being arranged such that an upper end portion of the tube surrounds at least a lower end portion of the shield grommet; and
an adhesive tape wound in a liquid tight manner from an outer periphery of the upper end portion of the tube over an outer periphery of the shield grommet.

2. The shield conduction path according to claim 1 , wherein the adhesive tape is wound downward from the shield grommet toward the tube in a spiral manner.

3. The shield conduction path according to claim 2 , further comprising a pipe grommet formed with a wire sealing portion through which the wires are caused to penetrate individually in a liquid tight manner and formed with a pipe sealing portion that seals an opening of a lower end of the shield pipe in a liquid tight manner.

4. The shield conduction path according to claim 1 , further comprising a pipe grommet formed with a wire sealing portion through which the wires are caused to penetrate individually in a liquid tight manner and formed with a pipe sealing portion that seals an opening of a lower end of the shield pipe in a liquid tight manner.

5. The shield conduction path according to claim 1 , wherein the lower end portion of the shield grommet is located at a height position corresponding to the connecting end portion of the shield pipe in an axial line direction of the shield pipe.
