Abstract

A shielded wire in which an insulation layer covered wire and a ground wire are both covered with a conductive material layer. The ground wire is covered, furthermore, with a conductive high molecular material layer. The latter and the conductive material layer are in mutual contact so that they are mechanically separable from each other and are, at the same time, electrically connected to each other. The conductive high molecular material layer may be made of conductive synthetic resin such as conductive polyvinyl chloride and the like, or of conductive rubber. The conductive material layer may also be made of the latter materials, as well as of metal.

Claims

1. A shielded wire suitable for use with a pressure clip connector, said wire consisting of a first wire having an electrical insulation layer thereon, a ground wire, an electrically-conductive high molecular material layer covering said ground wire, an electrically-conductive material layer covering both said first wire with electrical insulation layer and said ground wire with electrically-conductive high molecular material layer;

and an outer electrically-insulating layer covering said electrically-conductive material layer;

said electrically-conductive high molecular layer and said electrically-conductive material layer being in mutual contact so that they are mechanically separable from each other and are electrically connected to each other;

said electrical-insulation layer and said electrically conductive high molecular material layer being substantially equal in thickness and diameter to each other.

2. A shielded wire as defined in claim 1, wherein said electrically-conductive high molecular material layer is comprised of an electrically-conductive synthetic resin selected from the group consisting of electrically-conductive polyvinyl chloride and electrically-conductive rubber.

3. A shielded wire as defined in claim 1, wherein said electrically-conductive material layer is comprised of a material selected from the group consisting of electrically-conductive polyvinyl chloride and electrically-conductive rubber.

4. A shielded wire as defined in claim 2, wherein said electrically-conductive material layer is comprised of a material selected from the group consisting of electrically-conductive polyvinyl chloride and electrically-conductive rubber.
