Coaxial Cable Connector Replaceable Compression Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial cable connectors are 'craft sensitive' and require manual force for secure attachment, with limitations in handling different cable diameters and shield thicknesses, leading to potential loose connections and alignment issues due to recessed ferrules and non-detachable compression sleeves.
Innovation Solution
A male coaxial cable connector design featuring a detachable compression sleeve with a stepped axial conduit and detent mechanism, allowing easy removal and replacement of the compression ring for various cable sizes, and a deformable compression ring for secure engagement with the cable braid and jacket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a nondetachable compression sleeve is used, then the connector structure is simplified, but the ferrule becomes recessed and invisible, causing alignment difficulties during cable insertion
Solution Approach 1:
The compression sleeve is made detachable from the connector body, allowing it to be separated into two independent components. This segmentation enables the ferrule to be positioned visibly at the trailing end of the connector body while the compression sleeve can be removed or positioned separately, resolving the alignment visibility issue without requiring a completely different connector architecture.
2Device complexity
If a fixed compression ring is used, then the connector structure is simplified, but the connector cannot accommodate different cable diameters and shield thicknesses
Solution Approach 1:
The compression ring is made replaceable rather than fixed, transforming it from a static component to a dynamic, user-configurable element. Users can remove and replace compression rings with different inner diameters to match different cable sizes, enabling the connector to adapt to various cable specifications while maintaining a relatively simple overall structure.
Solution Approach 2:
The inner diameter parameter of the compression ring is made variable through replaceability. By allowing users to change the compression ring, the connector can accommodate different cable outer diameters and shield thicknesses, effectively changing the critical dimensional parameter to match different cable specifications.
3Reliability
If manual compression force is applied, then secure attachment is achieved, but the process becomes craft sensitive and requires substantial installer effort
Solution Approach 1:
The compression ring is designed to be self-compressing through its deformable material properties. When the compression sleeve is advanced, the deformable compression ring automatically compresses the cable jacket and braid without requiring substantial manual force from the installer, reducing the craft sensitivity and physical effort required while maintaining secure attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates secure and universal attachment of coaxial cables with different diameters and shield thicknesses, improving ease of use and reducing the risk of loose connections by providing a graspable compression sleeve and adjustable compression ring for precise fitting.
Implementation Method 1
the cable jacket and conductive braid are compressed against an annular barb disposed on the outer surface of the aforesaid underlying tubular shank during the final several millimeters of compressive travel
Implementation Method 2
The compression sleeve has a third axial conduit wherein the leading end of the third axial conduit is dimensioned to snugly overlie the outer diameter of the tubular body portion

AI summary
A male compression-type coaxial cable connector having an adapter nut attached to a leading end of a tubular connector body portion. The connector body portion has a first axial conduit with a barbed ferrule coaxially mounted therein. The connector further comprises a compression sleeve having a second axial conduit slidingly disposed over a trailing end of the tubular connector body portion. A deformable compression ring is removably disposed within the second axial conduit. In use, the prepared end of the coaxial cable is inserted through the compression sleeve and compression ring and advanced into the connector body conduit until it can be advanced no further. Subsequent advancement of the compression sleeve over the connector body portion, with the assistance of a compression tool, forces the deformable trailing end of the compression ring radially inward to compress the cable jacket and braid thereby providing secure attachment of the connector to the cable. The compression ring is removable and can be replaced with another compression ring having a different inner diameter to accommodate a variety of coaxial cables. The construction permits the compression sleeve to be easily removed for replacing the compression ring and easily reinstalled over the connector body after ring replacement.
