However, the existing wire sleeve has poor waterproof effect, which leads to external rainwater entering the box, easily causing water accumulation in the box. Therefore, a waterproof wire sleeve is proposed.

[0004] The specific technical scheme of the utility model is as follows: a waterproof wire sleeve, comprising: a flexible sleeve, a limiting groove is arranged on the outside of the flexible sleeve for being embedded in the through hole of the shell, sealing rings are arranged on the opposite surfaces of the limiting groove, and multiple groups of waterproof flexible membranes are arranged on the inner wall of the flexible sleeve, and the waterproof flexible membrane is provided with a gap for passing the wire harness.

[0005] Furthermore, the gap is in a Y-shape, a cross-shape or a M-shape.

[0006] Furthermore, a plurality of the waterproof flexible membranes are arranged in a staggered manner.

[0007] Furthermore, the flexible sleeve, the limiting groove and the waterproof flexible membrane are integrally formed by injection molding.

[0008] Furthermore, it also includes a water channel, which is placed in the flexible sleeve, the water inlet of the water channel is located at the bottom of the inner wall of the flexible sleeve, and the water outlet of the water channel is located at the end of the flexible sleeve, and the end is located outside the shell.

[0009] Furthermore, there are multiple water inlets, and the water inlets are located on both sides of the waterproof flexible membrane.

[0010] Furthermore, a filter screen is provided at the water inlet exposed to the outside.

[0011] Beneficial effects:

[0012] 1. In the present application, sealing rings are arranged on opposite surfaces of the limiting grooves, and the sealing rings are deformed when in contact with the shell, thereby improving the contact strength between the flexible sleeve and the shell, thereby improving the sealing performance.

[0013] 2. The present application provides multiple sets of waterproof flexible membranes. When the wiring harness passes through the gaps on the waterproof flexible membranes and contacts the waterproof flexible membranes, the waterproof flexible membranes are deformed. At the same time, the multiple waterproof flexible membranes are arranged in a staggered manner to form a non-completely sealed waterproof, which can effectively block external rainwater.

[0014] 3. This application further improves the waterproof effect by providing a waterway to discharge and guide rainwater entering the flexible pipe. At the same time, a filter is provided to prevent clogging by foreign objects, thereby increasing the service life. BRIEF DESCRIPTION OF THE DRAWINGS
