The invention relates to the field of wire sheaths, and particularly discloses a wire sheath with the sealing effect on an automobile firewall wire harness. The wire sheath comprises a skeleton, the two ends of the skeleton are respectively connected with a first wiring pipe and a second wiring pipe, the first wiring pipe and the second wiring pipe are arranged in a through manner, and the first wiring pipe and the second wiring pipe are connected with the skeleton. The edge of the end, at the second wiring pipe, of the framework is connected with a plurality of buckles used for being installed with the firewall in a clamped mode, the end, connected with the second wiring pipe, of the framework is integrally provided with a plurality of honeycomb-shaped noise reduction grids, the edge of the end, facing the second wiring pipe, of the framework is provided with a circle of sealing groove, and the interior of the sealing groove is in a Y shape. The internal honeycomb-shaped noise reduction grids can reduce the sound transmission speed and play a role in sound insulation and noise reduction. After the product is assembled, an internal vacuum state is formed, the sound transmission speed can be reduced, and the sound insulation and noise reduction effects are achieved. Due to the design of the Y-shaped sealing groove, the middle part also has a sealing effect, and the sealing effect is better due to three seals in total.

    本发明涉及护线套领域,具体的公开了一种对汽车防火墙线束具有密封作用的护线套,包括骨架,所述骨架的两端分别连接有第一走线管和第二走线管,第一走线管和第二走线管呈贯通设置,骨架在第二走线管那一端的边缘连接有若干个用于与防火墙卡接安装的卡扣,且骨架与第二走线管的连接端一体设置有若干个蜂窝状的降噪格,骨架朝向第二走线管那一端的边缘设置有一圈密封槽,密封槽的内部呈“Y”型。内部蜂窝状的降噪格可以降低声音传播速度,起隔音降噪作用。产品组装后形成内部真空状态,可以降低声音传播速度,实现隔音降噪作用。Y型密封槽的设计,使得中间部位也有密封作用,总共三道密封,密封效果更好。
