[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0023] It should be understood that in the description of this application, the orientation or positional relationship indicated by terms such as "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to this application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "a plurality" is two or more.

[0024] As Figure 1-2 As shown, for the water-blocking structure of the corrugated pipe in the embodiment of the present utility model, the corrugated pipe 1 is used to protect the wire harness. The water-blocking structure includes a mounting portion 2, a water-blocking portion 3, and a water guide column 4. When water flows along the corrugated pipe 1, the water-blocking portion 3 can collect, block, and guide the water flow, and make the water flow down from the water guide column 4 to avoid water entering the connector.

[0025] The mounting portion 2 is used for sealing and mounting on the outer wall of the corrugated pipe 1. Exemplarily, the mounting portion 2 and the corrugated pipe 1 are sealed with sealant.

[0026] The water-blocking portion 3 is in the shape of a frustum of a cone and includes a first opening 31 and a second opening 32 at both ends. One end of the water-blocking portion 3 with the first opening 31 is connected to the mounting portion 2. The orientation of the second opening 32 is opposite to the flowing direction of the water along the corrugated pipe 1. The inner diameter of the second opening 32 is larger than the inner diameter of the first opening 31. The inner wall of the water-blocking portion 3 has a diversion groove 33, and the diversion groove 33 is used for collecting the water flow on the inner wall of the water-blocking portion 3 and making the water flow in the direction of the second opening 32.

[0027] The water guide column 4 is arranged at the bottom of the second opening 32 and is connected to the water-blocking portion 3. The water guide column 4 is arranged vertically downward and is used for draining the water flow collected by the diversion groove 33 downward. So that the water flow will not flow along the surface of the water-blocking portion 3, having the effect of guiding the water flow.

[0028] Based on the above structural settings, the water-blocking structure of the present utility model can effectively prevent the water flow from being transmitted along the corrugated pipe and avoid the risk of electric leakage.

[0029] As Figure 2 As described, in one embodiment, the mounting portion 2 is tubular, and the inner diameter of the mounting portion 2 is equal to the inner diameter of the first opening 31. It is beneficial for the mounting portion 2 and the water-blocking portion 3 to be integrally formed.

[0030] Specifically, the corrugated pipe 1 is arranged horizontally. It is more beneficial for the water-blocking portion 3 to play the role of blocking water.

[0031] As Figure 1 shown, in one embodiment, the diversion groove 33 includes a confluence groove 33a and a plurality of flow collection grooves 33b. The confluence groove 33a is provided on the bottom inner wall of the water retaining part 3, and the flow collection grooves 33b are spirally arranged around the inner wall of the water retaining part 3. The flow collection grooves 33b are communicated with the confluence groove 33a. During use, the water flow of the blocking bellows 1 on the inner wall of the water retaining part 3 is first collected by the flow collection grooves 33b and then gathered into the confluence groove 33a.

[0032] Furthermore, the confluence groove 33a extends linearly from the first opening 31 to the second opening 32, and the end of the confluence groove 33a at the second opening 32 corresponds to the top of the water guiding column 4. The water flow gathered by the confluence groove 33a finally flows away along the water guiding column 4.

[0033] Specifically, the inner diameter of the first opening 31 is a, and the inner diameter of the second opening 32 is b, and b=(1.5 - 2.5)*a is satisfied. The water retaining part 3 is in the shape of a frustum of a cone. When the water flow on the bellows 1 flows from the second opening 32 to the first opening 31, since the diameter of the second opening 32 is larger than that of the first opening 31, the water flow will not flow along the surface of the water retaining part 3 and will only flow inside the water retaining part 3 and finally be discharged.

[0034] In one embodiment, the installation part 2 and the water retaining part 3 are integrally formed by rubber processing. Using a rubber structure has elasticity and is convenient for installation and use.

[0035] In addition, the wall thickness of the installation part 2 is equal to that of the water retaining part 3. This is beneficial to the integral molding of the installation part 2 and the water retaining part 3.

[0036] Specifically, the installation part 2 is connected with the bellows 1 by interference fit. This makes the connection between the installation part 2 and the bellows 1 firm.

[0037] In one embodiment, the depth of the diversion groove 33 does not exceed half of the wall thickness of the water retaining part 3. This enables the diversion groove 33 to have a diversion effect and also ensures the structural stability of the water retaining part 3.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
