Abstract
Abstract A wiring harness for a road vehicle includes a plurality of conductive leads each of which includes a conductive core in a synthetic resin sheath. The individual leads of the harness extend side by side wherever possible, and are secured together by means of a synthetic resin backing member which is fused to the sheaths of the leads. The leads are positioned in a predetermined pattern, and the synthetic resin backing member is engaged with the leads. A fusing tool is engaged with the backing member and is operated to fuse the backing member to the sheaths of the leads. The backing member can be a preform in the shape of the harness pattern, or alternatively can be in a number of separate parts individually fused to the leads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A wiring harness including a plurality of conductive leads each of which comprises a conductive core in a synthetic resin sheath, and a synthetic resin backing member, said plurality of leads including leads of at least two different diameters, and said leads being secured side by side by having their sheaths fused to said backing member, and wherein a first set of leads in the harness is fused to a first backing member part and a second set of leads of the harness is fused to a second backing member part, the first set extending on top of the second set, and the first and second set being secured together by interconnecting regions of their respective backing member parts.
Claim 2
Dependent Claim
119 words
A wiring harness including a plurality of conductive leads each of which comprises a conductive core in a synthetic resin sheath, and a synthetic resin backing member, said plurality of leads including leads of at least two different diameters, and said leads being secured side by side by having their sheaths fused to said backing member, and wherein a first set of leads in the harness is fused to a first backing member part and a second set of leads of the harness is fused to a second backing member part, the first set extending on top of the second set, and the first and second set being secured together by interconnecting regions of their respective backing member parts.
Claim 3
Independent Claim
115 words
A method of manufacturing a wiring harness, including the steps of arranging a plurality of conductive leads of two different diameters in a predetermined pattern, each lead comprising a conductive core in a synthetic resin sheath, engaging a synthetic resin backing member with the leads to form an assembly, engaging a resilient member with the assembly, and urging the leads and the backing member relatively towards one another by applying pressure to the assembly which deforms the resilient member while fusing the sheaths of the leads to the backing member, the deformation of the resilient member accommodating the differences in diameter of the leads thereby ensuring that all leads are fused to the backing member.
Claim 4
Independent Claim
115 words
A method of manufacturing a wiring harness, including the steps of arranging a plurality of conductive leads of two different diameters in a predetermined pattern, each lead comprising a conductive core in a synthetic resin sheath, engaging a synthetic resin backing member with the leads to form an assembly, engaging a resilient member with the assembly, and urging the leads and the backing member relatively towards one another by applying pressure to the assembly which deforms the resilient member while fusing the sheaths of the leads to the backing member, the deformation of the resilient member accommodating the differences in diameter of the leads thereby ensuring that all leads are fused to the backing member.
Claim 5
Dependent Claim
22 words
A method as claimed in claim 2, further including the step of preforming the backing member to the shape of the harness.
Claim 6
Dependent Claim
28 words
A method as claimed in claim 3, further including the step of fusing the backing member to the leads at spaced points along the lengths of the leads.
Claim 7
Dependent Claim
44 words
A method as claimed in claim 2, further including the steps of forming the backing member into a number of separate strips, and fusing each strip to respective runs of leads in the harness at spaced points along the lenGth of their respective runs.
Claim 8
Dependent Claim
39 words
A method as claimed in claim 2, further including the steps of forming the backing member into a plurality of separate pieces, and fusing each piece to the leads at points spaced apart along the lengths of the leads.
