[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear package tray disposed behind a vehicle.

[0002]

2. Description of the Related Art Conventionally, various units arranged in the rear portion of a vehicle are scattered, and a wire harness for supplying power to these units has been provided with a number of branch lines extending from a trunk line thereof.

[0003]

However, in order to fix the wire harness to the body (pressed iron plate), there are fixed parts (about 25 points in domestic luxury cars) for fixing the wire harness to the body and the body. Circuit (wire)
Exterior parts (almost all paths are vinyl tubes, urethane or resin exterior parts depending on the location) are required, and the cost of parts and the processing time to install it are large.

[0004] Also, the route design of the wire harness is conventionally performed by using other parts (mainly the body shape and the layout of auxiliary equipment).
Since the design of the parts is done after the design is completed, route design to avoid interference with other parts (change the shape and layout of the design department of each part, if it is not possible, review other paths and exterior A large number of man-hours are required for reviewing parts.

In addition, it is difficult and labor-intensive to carry a long wire harness (about 3 m, 3 kg for a third-number car) into a vehicle compartment and to perform a wiring operation.

Furthermore, since the connector is manually fitted, the number of working steps is long, and the connection reliability is poor, such as half-fitting or foreign matter mixing during fitting.

In view of the above problems, an object of the present invention is to provide a rear package tray for reducing the number of parts and man-hours required for assembling a wire harness to a vehicle and improving the reliability of electrical connection. I do.
