Rotatable Coaxial Adaptor Preventing Cable Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial cables are prone to bending damage when devices connected to them are moved, as the connectors cannot rotate, leading to reduced lifespan.
Innovation Solution
A rotatable coaxial adaptor comprising a first and second assembly with mounting blocks, insulators, contact pins, bearings, and rotary parts allows the coaxial cables to rotate, preventing bending and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coaxial connectors are fastened to devices, then electrical connection is established, but the connectors cannot rotate or move, causing the coaxial cable to bend and damage when devices are moved
Solution Approach 1:
The patent applies the dynamics principle by introducing rotatable mounting blocks and rotary parts that enable the coaxial adaptor to rotate and move with the connected devices. The first mounting block with first bearing and first rotary part, along with the second mounting block with second bearing and second rotary part, allow the coaxial cable connection point to dynamically adjust its position and orientation, preventing bending damage while maintaining electrical connection.
2Reliability
If coaxial connectors are fixed to devices, then stable electrical connection is achieved, but the coaxial cable is driven to bend when devices are moved
Solution Approach 1:
The patent uses the rotatable coaxial adaptor as an intermediary device between the coaxial cable and the connected devices. This adaptor with its rotating and movable components absorbs the mechanical stress and movement, allowing the electrical connection to remain stable while preventing the harmful bending forces from being transmitted to the coaxial cable.
3Object-affected harmful factors
If coaxial connectors are made movable, then cable bending is prevented, but the connector structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the connector system into separate functional modules: a stationary part that maintains electrical connection and a rotatable part with bearings and rotary components that handles movement. This modular segmentation allows the complexity to be localized to specific components while keeping the overall system manageable and the coaxial cable protection effective.

AI summary
A rotatable coaxial adaptor for linking high frequency coaxial cables has a first mounting block, a first bearing, a first rotary part, a connecting sleeve, a second bearing and a second mounting block. The first bearing and the first rotary part are mounted in the first mounting block and the first rotary part has a first joining tube connected to a coaxial cable. The connecting sleeve is secured to the first mounting block. The second bearing is mounted around the connecting sleeve. The second mounting block with a second joining tube connected to another coaxial cable is mounted around the second bearing and the connecting sleeve. With the structure mentioned above, the coaxial cables will not be driven to bend when devices connected to the coaxial cables are moved. Therefore, the coaxial cables can be protected from damage.
