Coaxial Connector Sleeve Locking Against Accidental Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors face issues such as time-consuming installation due to threaded connections, increased complexity and danger from wrench use, and accidental decoupling with push-pull connectors when waterproof covers are pulled.
Innovation Solution
A connector design featuring a coupling member with a sleeve that moves between locked and unlocked positions, guided by columnar members and secured by a spring, allowing for secure coupling and decoupling through a helicoidal motion, and a locking mechanism that prevents accidental decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded connection is used to connect coaxial connectors, then the connection strength is improved, but the installation time increases and installation complexity increases
Solution Approach 1:
The connection process is segmented into two independent stages: insertion/coupling and locking. The coupling member engages first to establish the connection, then the sleeve is rotated to engage the locking mechanism. This separates the functions of connection and locking, allowing quick coupling without threading while maintaining strong connection through the subsequent locking step.
Solution Approach 2:
The coupling member is designed to automatically engage and establish the electrical and mechanical connection before the locking mechanism is activated. This preliminary coupling action ensures that the connectors are properly aligned and connected prior to locking, eliminating the need for threading during the connection phase.
2Strength
If threaded connection is used to connect coaxial connectors, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional components: a coupling member for initial engagement and a separate locking mechanism activated by sleeve rotation. This segmentation allows each component to perform its specific function independently, simplifying the overall installation process compared to integrated threaded connections.
Solution Approach 2:
The locking mechanism transitions from a static threaded connection to a dynamic two-step process: first the coupling member engages statically, then the sleeve rotates dynamically to activate the locking mechanism. This dynamic approach replaces complex threading operations with simpler rotational motion.
3Productivity
If push-pull connector is used, then the installation speed is improved, but the connection reliability worsens due to accidental decoupling
Solution Approach 1:
The connector maintains the dynamic push-pull coupling mechanism for quick installation and removal, but adds a rotational locking dimension. The sleeve can be rotated to engage the locking mechanism that prevents accidental decoupling, while still allowing intentional decoupling through the original push-pull motion. This adds a degree of freedom to the system.
Solution Approach 2:
The locking mechanism provides preliminary anti-action against accidental decoupling forces. When the sleeve is rotated into the locked position, the locking mechanism preemptively counteracts any forces that might cause unintended separation, while preserving the ability to decouple intentionally through the push-pull motion.

Function Achieved in This Case
Facilitates quick and secure connection and disconnection of coaxial cables with tactile and aural feedback, reducing installation time and preventing unintended separation, while maintaining a firm connection.
Implementation Method 1
a spring tensioned between the outer conductor and sleeve that is capable of applying a rearward force to the sleeve
Implementation Method 2
the guiding section of the slot extends obliquely longitudinally and transversely relative to the sleeve such that movement of the sleeve between the locked position and the unlocked position comprises a helicoidal motion
