Abstract

An oil-cooled equipment harness includes a front end to be enclosed in a shielding case of an oil-cooled equipment for connecting to a terminal of a body of the oil-cooled equipment disposed in the shielding case, a wire including a conductor, a sheath including an insulating elastic member on a periphery side of the conductor, and a flexibility, a terminal fitting enclosing a portion of the conductor and a portion of the sheath of the wire, connecting to the conductor, and connecting to the terminal of the body of the oil-cooled equipment, a housing attached to shielding case and enclosing a periphery of the wire a predetermined distance away from the terminal fitting such that the wire is exposed from the terminal fitting, and an oil entry-preventing unit disposed between the wire and the terminal fitting for preventing oil in the shielding case from entering into the conductor.

First claim

What is claimed is:

1. An oil-cooled equipment harness, comprising:
a front end to be enclosed in a shielding case of an oil-cooled equipment for connecting to a terminal of a body of the oil-cooled equipment disposed in the shielding case;
a wire comprising a conductor, a sheath comprising an insulating elastic member on a periphery side of the conductor, and a flexibility;
a terminal fitting enclosing a portion of the conductor and a portion of the sheath of the wire, connecting to the conductor, and connecting to the terminal of the body of the oil-cooled equipment;
a housing attached to the shielding case and enclosing a periphery of the wire a predetermined distance away from the terminal fitting such that the wire is exposed from the terminal fitting; and
oil entry-preventing means disposed between the wire and the terminal fitting for preventing oil in the shielding case from entering into the conductor,
wherein the terminal fitting includes a metal and comprises a connecting part connecting to the terminal of the body, and a tubular part integrally formed with the connecting part as one piece for covering the portion of the conductor and the portion of the sheath from being exposed to the shield case,
wherein the oil entry-preventing means comprises the portion of the sheath crimped by a tubular crimping member formed at the tubular part, and
wherein the terminal fitting and the housing are relatively movable by the wire exposed between the terminal fitting and the housing.

2. The oil-cooled equipment harness according to claim 1 , further comprising:
oil leak-preventing means disposed between the housing and the shielding case for preventing the oil in the shielding case from leaking out of the shielding case.

3. The oil-cooled equipment harness according to claim 1 , wherein the oil entry-preventing means comprises a rubber ring fitted to a sealing groove formed on a periphery of the housing.

4. The oil-cooled equipment harness according to claim 1 , wherein the conductor comprises plural thin wires.

5. The oil-cooled equipment harness according to claim 1 , wherein adhesives are coated on nearly a back half part of the housing, and the adhesives are covered with a heat shrinkable tube.

6. The oil-cooled equipment harness according to claim 1 , wherein the oil-cooled equipment comprises an oil-cooled motor or an oil-cooled equipment.

7. The oil-cooled equipment harness according to claim 1 , wherein the housing comprises a flange for attaching the housing to the shielding case.

8. The oil-cooled equipment harness according to claim 1 , wherein the tubular crimping member is provided at a back end side of the terminal fitting.

9. The oil-cooled equipment harness according to claim 1 , wherein the insulating elastic member is exposed from the wire in the housing.

10. The oil-cooled equipment harness according to claim 1 , further comprising another oil entry-preventing means located at a position closer to the shielding case than the insulating elastic member in the housing for preventing the oil in the shielding case from entering into the insulating elastic member.

11. The oil-cooled equipment harness according to claim 1 , wherein the portion of the conductor comprises a front end part of the wire located between the terminal and the housing.

12. The oil-cooled equipment harness according to claim 1 , wherein a front half part of the terminal fitting includes a flat plate, is provided with a bolt hole, and is attached to the terminal by a bolt.

13. The oil-cooled equipment harness according to claim 12 , wherein a back half part of the terminal fitting is formed tubular such that the conductor is inserted into the tubular part of the terminal fitting and connected thereto by being crimped by the tubular crimping member on a back end side of the terminal fitting.

14. The oil-cooled equipment harness according to claim 1 , wherein a back half part of the terminal fitting is formed tubular such that the conductor is inserted into the tubular part of the terminal fitting and connected thereto by being crimped by the tubular crimping member on a back end side of the terminal fitting.
