Coaxial Cable Retention Connection for Tool-Free Shielded Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connection devices with connectors occupy significant space, require time-consuming assembly, and often necessitate the use of tools and non-detachable connectors that can damage cables and limit installation flexibility.
Innovation Solution
A connection device that houses the coaxial cable without connectors, utilizing a retention element that moves between positions to secure the cable, allowing for tool-free installation and reduced space requirements, while maintaining electromagnetic shielding and electrical continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are used in coaxial connection devices, then electrical continuity and mechanical fastening are ensured, but the space occupied by the device increases significantly
Solution Approach 1:
The invention extracts and eliminates the connector component from the coaxial connection device. Instead of using traditional male/female connectors, the patent employs a connection device that directly receives and secures the coaxial cable through a retention mechanism (screw or spring) that engages with the cable's outer jacket, removing the bulky connector assemblies entirely while maintaining electrical continuity through direct contact with the cable conductors
Solution Approach 2:
The invention inverts the traditional connection approach by having the connection device actively engage the cable rather than the cable engaging a connector. The retention means (screw or spring) applies force to clamp the cable against contact elements, reversing the conventional paradigm where connectors are passive receptacles waiting for cable insertion
2Reliability
If connectors are used in coaxial connection devices, then mechanical fastening is achieved, but the assembly time increases
Solution Approach 1:
The invention enables self-service installation where the operator directly manipulates the retention mechanism (screw or spring) to secure the cable. The design eliminates the need for specialized connector assembly tools and procedures, allowing the installer to perform the entire connection process using basic hand tools or even finger pressure in the case of spring mechanisms, significantly reducing assembly time and complexity
3Reliability
If non-detachable connectors are used, then mechanical fastening is secure, but cable replacement requires cutting the cable
Solution Approach 1:
The invention introduces dynamic, reversible retention mechanisms (screw or spring) that allow the cable to be easily inserted and removed without damage. The retention means can be actuated to release the cable grip, enabling complete cable replacement by simply pulling the cable out of the connection device, thereby providing full adaptability for cable maintenance and upgrades
4Reliability
If connectors are used, then electrical continuity is ensured, but the cost of the device increases
Solution Approach 1:
The invention replaces expensive, precision-machined connector components with simpler, more economical elements. The connection device uses basic retention mechanisms (standard screws or springs) and simple contact elements rather than precision-molded connector housings and interfaces, significantly reducing material and manufacturing costs while maintaining adequate electrical continuity for the application
