Branching Guide Sleeve Structure for Waterproof Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide sleeves for cables allow gaps to form between the cable and the through holes, leading to water leakage due to the fixed positions of the through holes, which can be penetrated by external rainwater.
Innovation Solution
A guide sleeve design with branching guide portions from the main body, sealed by a sealing portion, ensuring the guide portions move independently to prevent gaps and maintain waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the through holes are fixed in position on the end face of the main body, then the structure is simple and easy to manufacture, but gaps form between the through holes and cables when cables move, causing water leakage
Solution Approach 1:
The guide sleeve is divided into a main body and multiple independent guide portions that branch from it. Each guide portion contains a through hole and can move independently with its corresponding cable, while the main body remains relatively stable. This segmentation allows each component to perform its specific function optimally without compromising the overall structure.
Solution Approach 2:
The guide portions are designed to be flexible and movable relative to the main body, allowing them to dynamically adjust their position as cables move. This dynamic capability ensures that the through holes remain in contact with the cables during operation, maintaining waterproof sealing without requiring a completely rigid fixed structure.
2Reliability
If multiple cables pass through fixed through holes, then the mounting is simple, but when cables move in different directions, forces are applied that create gaps and allow water entry
Solution Approach 1:
By separating the guide portions from the main body and allowing them to move independently, each cable can move in its own direction without affecting the positioning of other cables. The guide portions act as independent units that accommodate individual cable movements while maintaining overall structural integrity and waterproof sealing.
Solution Approach 2:
The guide portions are designed with dynamic movement capabilities that allow them to follow cable movements in any direction. This dynamic design enables the guide portions to maintain contact with moving cables while the main body remains relatively stable, ensuring continuous waterproof sealing during cable operation.

AI summary
A guide sleeve with good waterproof performance. A plurality of cables passing through a mounted portion are fixed and guided by a plurality of through holes penetrating the guide sleeve. The guide sleeve includes: a mounting portion, where the mounting portion is mounted on the mounted portion, and one end of each through hole is opened in the mounting portion; a main body portion, where the main body portion is connected to the mounting portion; and a plurality of guide portions, where the plurality of guide portions branch from the side of the main body portion opposite to the mounting portion, each through hole penetrates the corresponding guide portion, and the other end of each through hole is opened at an end of the corresponding guide portion away from the main body portion.
