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.RTM.-like material to the wiring board. When the harness assembly is complete, it is removed and placed in an electronic chassis having corresponding Velcro.RTM.-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.
