Abstract
A transmission cable assembly is connected between an ignition coil and a spark plug to transmit a high voltage generated by the ignition coil to the spark plug for ignition of a fuel-air mixture. The transmission cable assembly includes a transmission cable and a grounding unit. The transmission cable includes a high-voltage wire for transmission of high voltage and an insulation jacket wrapped around an outside surface of the high-voltage wire. The grounding unit is made of an electrically conductive substance and includes a grounding layer and multiple grounding wires. The grounding layer completely covers and tightly engages the insulation jacket. The grounding wires each have an end connected to an inside surface of the grounding layer.
