Abstract

A wiring harness includes wires (10), terminal fittings (20) connected respectively to end parts of the wires (10), and a sheet (30) to which the wires (10) and at least a part of the terminal fittings (20) along which the wires (10) are disposed are sewn by a sewing thread (T). Accordingly, the wires (10) cannot be pulled singly. Further, if the wires (10) are pulled together with the sheet (30), a pulling force is dispersed to the wire (10) and the sheet (30) so that the pulling force on the wire (10) is reduced. In addition, since at least a wire arranging portion (23) of the terminal fitting (20) along which the wire (10) is disposed is sewn to the sheet (30) by the sewing thread (T), detachment of the wire (10) from the terminal fitting (20) is prevented.

First claim

The invention claimed is:

1. A wiring harness, comprising:
a wire;
a terminal fitting connected to an end part of the wire; and
a sheet, at least a part of the terminal fitting along which the wire is disposed being sewn to the sheet and a part of the wire extending from the terminal fitting being sewn to the sheet.

2. The wiring harness of claim 1 , further comprising:
a housing for accommodating the terminal fitting, and wherein:
the housing is made of a synthetic resin and is sewn to the sheet.

3. The wiring harness of claim 1 , wherein the sheet has a front edge, and the terminal fitting has a terminal body projecting forward from the front edge of the sheet, the terminal body being configured for connection to a mating terminal.

4. The wiring harness of claim 3 , wherein the terminal fitting has a step between the terminal body and the front edge of the sheet, the step being configured so that a surface of the sheet opposite the wire is substantially flush with a surface of the terminal body.

5. The wiring harness of claim 1 , wherein the part of the terminal fitting that is sewn to the sheet has a U-shaped cross-section that is open along a side facing away from the sheet, and the wire being positioned in the U-shaped part of the terminal fitting.

6. The wiring harness of claim 1 , wherein the wire has a conductive core and an insulation coating covering at least part of the conductive core, the conductive core being exposed from the insulation coating at areas of the wire adjacent the end part of the wire, the terminal fitting being crimped to the conductive core exposed from the insulation coating of the wire.

7. The wiring harness of claim 6 , wherein the insulation coating is on areas of the wire that are sewn to the sheet.

8. A wiring harness comprising:
a wire;
a terminal fitting connected to an end part of the wire;
a housing for accommodating the terminal fitting; and
a sheet, the wire and at least a part of the terminal fitting along which the wire is disposed being sewn to the sheet, wherein:
the housing and the sheet include locking structures to be fit and locked to each other.

9. The wiring harness of claim 8 , wherein the housing is sewn to the sheet.

10. A wiring harness, comprising:
wires;
terminal fittings, each of the terminal fittings having opposite front and rear ends, a terminal body adjacent the front end of each of the terminal fittings and being configured for connection to a mating terminal fitting, a wire arranging portion adjacent the rear end of each of the terminal fittings, the wire arranging portions being connected respectively to front end parts of the wires so that the wires extend rearward from the terminal fittings; and
a sheet, at least a part of the wire arranging portion of each of the terminal fittings along which the respective wires are disposed and areas of each of the wires rearward of the terminal fitting being sewn to the sheet.

11. The wiring harness of claim 10 , further comprising:
a housing accommodating the terminal fittings, wherein:
the housing and the sheet include locking structures to be fit and locked to each other.

12. The wiring harness of claim 11 , wherein the housing is sewn to the sheet.

13. The wiring harness of claim 10 , further comprising:
a housing accommodating the terminal fittings, and wherein:
the housing is sewn to the sheet.
