The invention discloses a wire harness assembly of a power generator. The wire harness assembly comprises a plug and a corrugated pipe, the plug is provided with a starting wire harness, a voltage stabilizing wire harness and an outgoing wire harness, the external surfaces of the starting wire harness, the voltage stabilizing wire harness and the outgoing wire harness are provided with an anti-wearing layer, the corrugated pipe is provided with radiating holes, the two ends of the corrugated pipe are buckled with dustproof plugs respectively, and each dustproof plug is provided with branching holes, and is made of an elastic material, and a support is arranged under the corrugated pipe. Due to arrangement of the anti-wearing layer, the wear resistance of wires is improved, and the service life is prolonged; the radiating holes are arranged in the corrugated pipe, and heat radiation is prompted; the two ends of the corrugated pipe are buckled with the dustproof plugs respectively, each dustproof plug is provided with the branching holes, and friction among the wires is reduced; the support is arranged under the corrugated pipe, and plays a bearing role to prevent the wires from falling off; the dustproof plug is trumpet-shaped to increase the distance among the branching holes; and the structure is simple, and use is convenient.
