Abstract

A shielded harness is simply constructed such that covered wires are fitted into a groove of a molded body, and then an opening of the groove is covered with a metal casing. This simple structure allows noise to be released to the metal casing, which functions as a ground, via a metal plate constituting the molded body when the noise is generated at a control system unit or comes from an external device. The metal casing of the shielded harness can be used as a housing of a device, such as a power converter, and therefore, a fixing tool is not required for wiring, and the wiring is made easy. Moreover, compared with a conventional shielded wire, this shielded harness has a small number of parts and is produced by an easy method, thereby allowing reduction in production cost.

First claim

What is claimed is:

1. A shielded harness comprising:
a covered wire having a connector at each end of the covered wire;
a molded body containing a conductive material and having a groove for receiving the covered wire;
a metal casing arranged to close an opening of the groove of the molded body and electrically connected to the molded body; and
a fixing part that fixes the molded body to the metal casing,
wherein the molded body is made of a conductive resin.

2. The shielded harness according to claim 1 , wherein the groove of the molded body has a U shape sectional shape and surrounds the covered wire from three directions.

3. The shielded harness according to claim 1 , further comprising a tape that closes a part of the opening of the molded body to secure the covered wire in the inside of the groove.

4. The shielded harness according to claim 1 , further comprising a resin fixing tool that closes a part of the opening of the molded body to secure the covered wire in the inside of the groove.

5. The shielded harness according to claim 1 , wherein the fixing part is a metal screw.

6. A shielded harness comprising: a covered wire having: a connector at each end of the covered wire; a molded body, containing a conductive material and having a groove for receiving the covered wire; a metal casing arranged to close an opening of the groove of the molded body and electrically connected to the molded body; a fixing part that fixes the molded body to the metal casing; and a resin fixing tool that closes a part of the opening of the molded body to secure the covered wire in the inside of the groove.

7. The shielded harness according to claim 6 , wherein the molded body includes a conductive metal plate and an insulative resin that covers the metal plate, and a part of the metal plate is exposed from the insulative resin and is fixed to the metal casing with the fixing part.

8. The shielded harness according to claim 6 , wherein the groove of the molded body has a U shape sectional shape and surrounds the covered wire from three directions.

9. The shielded harness according to claim 6 , wherein the fixing part is a metal screw.
