Cable harnesses are essential assembly components that provide the electrical interconnectivity between different modules within a electromechanical product. The design and planning of cable harness assembly is a very complicated, time-consuming and key problem. Currently the design and manufacture of cable harness assembly have remained a labor intensive process. In this paper firstly the published academic in the design and planning of cable harness is reviewed. Then on the basis of analysis, its development orientations are proposed including CAD technologies, artificial intelligence, virtual reality and three-dimensional visual assembly.
