The waterproof automobile tail door wire harness assembly comprises a corrugated pipe, waterproof covers are connected to the two ends of the corrugated pipe in a sealed mode, sealing bosses are arranged on the waterproof covers, a wire harness body is arranged in the corrugated pipe in a penetrating mode, an air pipe communicated with the interior of the corrugated pipe is arranged in the center of the wire harness body, and sealing plugs penetrating into the waterproof covers are arranged at the two ends of the wire harness body respectively. The sealing plug comprises a first plug body and a second plug body connected to the first plug body, the first plug body is provided with a sealing expansion body and an air cavity, and an air generator capable of enabling the sealing expansion body to expand and then wrap the outer wall of the sealing boss is arranged in the air cavity; the first plug body is movably provided with a valve element, one end of the valve element penetrates into the sealing expansion body in a sealed mode, and the sealing expansion body can drive the valve element to slide during expansion so that the valve element can communicate the air cavity with the air pipe. Damage caused by contact friction between the wire harness body and the inner wall of the corrugated pipe in the opening and closing process of the automobile tail door is effectively avoided, and the structural use reliability is higher.

    本发明公开了一种防水型汽车尾门线束总成,包括波纹管,波纹管的两端均密封连接有防水罩,防水罩设有密封凸台,波纹管内穿设有线束体,线束体中心设有与波纹管内部连通的气管,线束体的两端分别设有贯穿入防水罩内的密封插头;密封插头包括第一插头本体和连接在第一插头本体上的第二插头本体,第一插头本体设有密封膨胀体和气腔,气腔内设有能够使密封膨胀体发生膨胀后对密封凸台外壁进行包覆的气体发生器;第一插头本体活动设有阀芯,阀芯一端密封穿入密封膨胀体内,密封膨胀体在膨胀时能够带动阀芯滑动,以时阀芯将气腔与气管连通;有效避免线束体在汽车尾门开闭过程中与波纹管内壁发生接触摩擦而造成破损,结构使用可靠性更高。
