Abstract
Abstract An electrical harness is assembled on a board having detachable wire holders so that the entire unit can be readily transferred to an electrical chassis. The wire holders include tie wraps that are attached with a Velcro®-like material to the wiring board. When the harness assembly is complete, it is removed and placed in an electronic chassis having corresponding Velcro®-like targets. Assembly of the wire harness is faciltated by a microprocessor which indicates where each individual wire begins and ends. The microprocessor controls a group of wire terminator units each of which include a greed LED and a red LED for indicating the beginning and end of a wire. Each wire terminator unit also includes an LED/photodiode circuit for detecting the presence or absence of a wire. Therefore, the harness assembler is directed by the microprocessor to route a wire through a specific location. If a wire has been correctly routed, as determined by the LED/photodiode detection units, then the assembler is instructed to proceed with the next wire step. The invention significantly improves the efficiency, accuracy, and economy associated with the assembly of electrical harnesses for electronic devices.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
165 words
A method for assembling an electrical wire harness comprising the steps of: locating wire end terminating means having a Velcro®-like base on a wiring board at locations where wires are to begin and end; locating wire gathering units having Velcro®-like surfaces on their bases on said wiring board along the path where the wires of the electrical harness will pass; routing wires from wire end terminator units through wire gathering units until the complete wire harness is formed; tightening the wire gathering units so that the wires of the electrical harness stay in place; removing the assembled electrical harness and wire gathering units assembly from said wiring board; placing the assembled electrical harness in an electrical chassis having electronic components therein so that the Velcro®-like surfaces of the wiring gathering mate units with Velcro®-like targets on the electrical chassis thereby securing the harness to the electrical chassis; and, connecting the free wire ends of the electrical harness to the electrical components on the electronic chassis.
Claim 2
Independent Claim
165 words
A method for assembling an electrical wire harness comprising the steps of: locating wire end terminating means having a Velcro®-like base on a wiring board at locations where wires are to begin and end; locating wire gathering units having Velcro®-like surfaces on their bases on said wiring board along the path where the wires of the electrical harness will pass; routing wires from wire end terminator units through wire gathering units until the complete wire harness is formed; tightening the wire gathering units so that the wires of the electrical harness stay in place; removing the assembled electrical harness and wire gathering units assembly from said wiring board; placing the assembled electrical harness in an electrical chassis having electronic components therein so that the Velcro®-like surfaces of the wiring gathering mate units with Velcro®-like targets on the electrical chassis thereby securing the harness to the electrical chassis; and, connecting the free wire ends of the electrical harness to the electrical components on the electronic chassis.
