The invention discloses an automobile electrical wiring harness connecting and fixing structure. The structure comprises: a fixing part fixedly arranged on an automobile body, wherein an installationcavity is arranged in the fixing part, and openings are formed in two opposite side walls of the installation cavity; a movable part movably clamped in the installation cavity, wherein the movable part penetrates through a body of the movable part and is provided with a wire passing channel for an electrical wiring harness to penetrate through, and the movable part is provided with a locking pieceused for being fixedly connected with the electrical wiring harness; and a connecting part which is arranged in the installation cavity and is positioned between the fixing part and the movable part,one end of the connecting part is fixedly connected with the inner side wall of the installation cavity, the other end of the connecting part is fixedly connected with the movable part body, and an elastic telescopic section is arranged in the middle of the connecting part. Based on the automobile electrical wiring harness connecting and fixing structure, the electrical wire harness has movementallowance in the axial direction and the circumferential direction, and the stress gathered on the surface of the electrical wire harness in a short time can be effectively reduced, so that the electrical wire harness can still work normally when the local part of an automobile body deforms, and the reliability of an automobile electrical system is improved.

    本发明公开一种汽车电气线束连接固定结构,包括固定部,固定设于车身上,其内部设有安装腔体,安装腔体的两相对侧壁上开设有开孔;活动部,活动卡设于安装腔体中,活动部贯穿其本体设有供电气线束穿过的过线通道,活动部上设有用于与电气线束固定连接的锁紧件;连接部,设于安装腔体内部且位于固定部与活动部之间,其一端与安装腔体的内侧壁固定连接,另一端与活动部本体固定连接,其中部设为弹性伸缩段,基于上述汽车电气线束连接固定结构,电气线束具有沿其轴向与周向的活动余量,能够有效的降低电气线束在短时间内聚集于其表面的应力,从而能够保证汽车车身局部产生形变时,电气线束仍然能够正常的工作,提升汽车电气系统的可靠性。
