The invention relates to the technical field of automobile air conditioner wire harnesses, and discloses a flame-retardant and high-temperature-resistant automobile air conditioner wire harness and a preparation method thereof.The flame-retardant and high-temperature-resistant automobile air conditioner wire harness comprises a wire harness body, the two ends of the wire harness body are each connected with an integrally-formed wire harness connector, and the wire harness body comprises a plurality of evenly-distributed core bodies and an inner sleeve body arranged on the surfaces of the core bodies in a sleeving mode; the wire harness comprises a wire harness main body, a plurality of inner sleeve bodies are arranged in the wire harness main body, a connecting belt is arranged between every two adjacent inner sleeve bodies for connection, the outer side of the wire harness main body is sleeved with a flame-retardant sheath, a ceramic filling layer is filled between the flame-retardant sheath and the inner sleeve bodies, a high-temperature-resistant shell is arranged on the outer side of the flame-retardant sheath, and the high-temperature-resistant shell comprises an upper shell body and a lower shell body. According to the invention, the core bodies can be separated from each other through the connecting belt and the inner sleeve body, high-temperature faults caused by the influence of mutual winding of the core bodies on heat dissipation are prevented, and multi-layer flame-retardant protection can be carried out on the outer side of the wire harness main body through mutual cooperation of the ceramic filling layer and the high-temperature-resistant shell.
本发明涉及汽车空调线束技术领域,且公开了一种阻燃耐高温的汽车空调线束及其制备方法,包括线束主体,所述线束主体的两端均连接有一体成型的线束接头,所述线束主体包括若干均匀分布的芯体,以及套设在芯体表面的内套体,相邻的所述内套体之间设置有连接带进行连接,所述线束主体的外侧套设有阻燃护套,所述阻燃护套与内套体之间填充有陶瓷填充层,所述阻燃护套的外侧设有耐高温外壳,所述耐高温外壳包括上壳体和下壳体。本发明中通过连接带和内套体可将各个芯体相互分隔,避免防止芯体之间相互缠绕影响散热而引起高温故障,通过陶瓷填充层和耐高温外壳相互配合,可在线束主体的外侧进行多层阻燃防护。
