Universal Coaxial Cable Compression Tool with Radial Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression tools for coaxial cables require multiple tools or components to accommodate different connector sizes, leading to inefficiencies and inconvenient release mechanisms, particularly with RG-11 F-type connectors.
Innovation Solution
A tool with a pair of movable anvils and a fixed anvil, equipped with spring clips and a compression zone design that allows easy insertion and release of various connector sizes without the need for multiple tools, using a plunger to compress the connector and a radial movement to remove the finished cable/connector combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate inserts or plungers are provided to accommodate different connector sizes, then the tool can handle various connector types, but the technician must change out tool parts every time a different size connector is encountered, losing time and requiring multiple components
Solution Approach 1:
The compression tool employs a universal compression chamber with multiple fixed compression zones that can accommodate different connector sizes without requiring part changes. The chamber is designed with varying zone locations and dimensions to handle multiple connector types using the same tool components.
Solution Approach 2:
The compression chamber is segmented into multiple distinct compression zones, each optimized for specific connector sizes. This segmentation allows the single tool to handle various connector types by selecting the appropriate zone, eliminating the need for multiple removable inserts or plungers.
2Adaptability or versatility
If split bases are used to accommodate different connector sizes in a single tool, then the tool can handle various sizes, but the user cannot readily release the finished cable/connector combination without awkward manipulation of the split bases
Solution Approach 1:
The compression tool automatically releases the finished cable/connector combination through a spring-loaded mechanism that propels the compressed assembly forward upon completion of compression. This self-service release eliminates the need for manual manipulation of split bases or other releasing mechanisms.
3Device complexity
If the compression chamber is sized for a single connector type, then the tool structure is simple, but several separate tools are required to accommodate all connector sizes
Solution Approach 1:
The compression tool employs a universal compression chamber with multiple fixed compression zones that can accommodate different connector sizes without requiring part changes. The chamber is designed with varying zone locations and dimensions to handle multiple connector types using the same tool components.
Solution Approach 2:
Multiple compression zones for different connector sizes are merged into a single compression chamber structure. This integration allows the tool to handle various connector types in one device, eliminating the need for multiple separate tools while maintaining structural simplicity.
4Ease of operation
If the aperture in the anvil is large enough to permit easy entry and exit of cable, then cable can be easily inserted, but the aperture cannot apply sufficient retention force to prevent cable from moving around or coming out inadvertently prior to compression
Solution Approach 1:
The anvil aperture incorporates a localized retention mechanism, such as a clamp or grip feature, that applies retention force only to the cable portion within the aperture. This localized action secures the cable during handling while maintaining easy insertion and allowing straightforward removal after compression.
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
Enables efficient installation and removal of compression connectors of various sizes and types on coaxial cables without the need for multiple tools or components, improving convenience and usability by allowing easy radial removal of the finished cable/connector combination.
Implementation Method 1
The anvils each have a pair of movable spring clips with a depression or cutout in an edge thereof such that opposed spring clips define the cable-receiving receptacle
Implementation Method 2
A compressive force then is applied to the ends of the connector to deform the connector and complete the installation

AI summary
A tool for installing compression connectors of various sizes and types on the end of a coaxial cable has a base mounting a pair of movable anvils for engaging two different lengths of connectors. The base further incorporates a fixed anvil for engaging a third length of connector. The movable anvils define an aperture which is shaped to permit easy entry and exit of a cable while still applying a suitable retention force to an inserted cable. A connector seating holder is formed in the front of the tool. A slidably mounted plunger cooperates with the anvils to compress a connector. The plunger has a push head and a slide rod. A lock nut is threaded on the push head and is engageable with the slide rod to prevent rotation of the push head.
