Waterproof Cable Sleeve With Deformable Ribs for Socket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transmission cables are prone to moisture ingress through gaps at the socket interface, leading to unstable signal transmission and potential corrosion, especially in humid environments.
Innovation Solution
A sleeve with outwardly protruding ribs is mounted on the cable, which elastically deforms to seal against the socket's inner wall, preventing moisture ingress and maintaining electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional transmission cable plug is inserted into a socket, then electrical connection is established, but gaps remain at the socket interface allowing moisture ingress
Solution Approach 1:
The patent employs a flexible waterproof sleeve with multiple deformable ribs that conform to the socket interface. The ribs are made of elastic material that deforms under insertion pressure to create a tight seal, preventing moisture ingress while maintaining electrical connection stability.
Solution Approach 2:
The patent utilizes the elastic deformation property of the rib material, changing its physical state from rigid to flexible during insertion. The ribs deform under pressure to match the socket's inner wall geometry, creating an adaptive seal that blocks moisture while preserving electrical conductivity.
2Reliability
If multiple ribs are added to the sleeve to improve sealing, then waterproofing capability increases, but device complexity increases
Solution Approach 1:
The waterproof sleeve is segmented into multiple independent ribs spaced circumferentially around the cable. Each rib acts as an independent sealing element that can deform and contact the socket wall separately, providing comprehensive coverage and reliable waterproofing through distributed segmentation rather than a single complex structure.
3Reliability
If the ribs are made deformable to seal against the socket, then sealing effectiveness improves, but manufacturing precision requirements increase
Solution Approach 1:
The ribs are designed to be self-sealing through their inherent elastic properties. During cable insertion, the ribs automatically deform under the applied pressure to conform to the socket's inner wall geometry, creating a seal without requiring external actuation or complex control mechanisms. The material's elasticity enables automatic adaptation to dimensional variations.
Solution Approach 2:
The patent exploits the elastic deformation characteristic of the rib material, allowing it to change its physical dimensions dynamically during insertion. This parameter change enables the ribs to accommodate variations in socket dimensions and maintain effective sealing despite manufacturing tolerances, reducing precision requirements.

AI summary
A waterproof structure for a transmission cable includes a transmission cable which includes a transmission head and a connecting wire. The transmission head includes a plug segment and a neck segment. A sleeve has a through hole defined axially therethrough, and the sleeve is mounted to the plug segment of the transmission cable. Multiple ribs are circumferentially formed on an outer peripheral surface of the sleeve. Each rib extends outwardly from the outer peripheral surface of the sleeve. The ribs are spaced apart from the others. Each rib is deformed when subjected to pressure. When the transmission cable is inserted into a socket, any of the ribs can seal the socket interface according to the depth of insertion, so as to effectively prevent external moisture, liquids, and other contaminants from entering the socket.
