Abstract

An object of the present invention is to provide a clamp-integrated wiring harness protector for assembling, in which a man-hour for assembling the protector is unnecessary, and workability upon assembling with a wiring harness is satisfactory, and the wiring harness is protected after assembling, and the protector can be produced at low cost. The clamp-integrated wiring harness protector for assembling including: a sheet-shaped portion; and a clamp portion integrally formed with the sheet-shaped portion.

First claim

The invention claimed is:

1. A clamp-integrated wiring harness protector for assembling, comprising:
a sheet-shaped portion formed using a thermoplastic resin sheet so as to surround a wiring harness; and
a clamp portion provided in the sheet-shaped portion for inserting into and locking with a locking hole provided on a vehicle body,
wherein the clamp portion and the sheet-shaped portion are integrally formed with each other under thermoforming process using the thermoplastic resin sheet, thereby preventing a displacement of the wiring harness upon assembling to a vehicle,
wherein the sheet-shaped portion includes a first semi-cylindrical member with the clamp portion integrally formed thereon, and a second semi-cylindrical member, and
wherein both circumferential ends of the first semi-cylindrical member are adhered to or heat sealed to both circumferential ends of the second semi-cylindrical member, respectively.

2. A method for producing the clamp-integrated wiring harness protector for assembling as claimed in claim 1 , comprising the step of:
thermoforming using the thermoplastic resin sheet with a molding die to obtain the protector,
wherein the molding die is divided to a plurality of partial molding dies in a longitudinal direction of a wiring harness to be held by the protector, and the partial molding dies are combined to compose the molding die, and
wherein at least one of the partial molding dies has a clamp forming portion.

3. The method as claimed in claim 2 , wherein at least one of the partial molding dies is used for forming a corrugate-shaped portion.
