Angled Coaxial Connector with Rotatable Coupling Nut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Larger coaxial connectors face installation challenges due to obscured coupling nuts and mechanical instability, particularly with 7/16 inch hex sizes, and struggle with environmental sealing and assembly complexity in angled designs.
Innovation Solution
An angled coaxial connector with a dual-grip coupling nut and a 'pop-up pin' feature, utilizing an insulating member and pin configuration that provides a visual installation indicator and environmental sealing, along with a rotatable coupling nut mechanism for easier handling and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If larger connector bodies (9/16 inches diameter) are used to accept series 11 cable, then cable compatibility is improved, but coupling nut accessibility is worsened
Solution Approach 1:
The coupling nut is segmented from the connector body through a rotatable attachment mechanism, allowing it to be moved independently. This enables the coupling nut to be rotated out from behind the large connector body to an accessible position for installation and removal, while the connector body remains large enough to accept series 11 cable.
2Adaptability or versatility
If 7/16 inch hex coupling nuts are used on large connectors, then standard tool compatibility is improved, but rotational movement is worsened due to o-ring impingement
Solution Approach 1:
The coupling nut is made dynamically movable through a rotatable attachment mechanism rather than being fixed. This allows the coupling nut to rotate freely during installation and removal operations, preventing the o-ring from impeding rotational movement while maintaining the standard 7/16 inch hex configuration for tool compatibility.
3Ease of manufacture
If fixed pin configurations are used in angled connectors, then manufacturing simplicity is improved, but installation indication is worsened
Solution Approach 1:
The pin is configured to move dynamically from a retracted position during assembly to a protruding position that indicates proper cable installation. This movable pin provides visual feedback to the installer that the cable is properly seated, while requiring minimal manufacturing complexity compared to fixed indication mechanisms.
4Ease of operation
If rotatable coupling nut mechanisms are added, then ease of installation is improved, but device complexity is worsened
Solution Approach 1:
The coupling nut mechanism is segmented into discrete, simple components that attach to the connector body. This modular approach allows the rotatable coupling nut to be implemented with minimal additional complexity, maintaining ease of installation while avoiding overly complex mechanisms.

AI summary
A coaxial angle connector includes a pin having first and second ends, the first end being generally perpendicular to the second end. The pin is moveable from a first position to a second position in response to insertion of a coaxial cable into the connector and provides a positive visual indication of proper cable center conductor installation. The connector can also optionally include an coupling nut with a dual-grip surface.
