RF Cable Test Adapter With Quick Self-Locking Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing the electrical performance of cables and cable assemblies often result in damage, high costs, and measurement errors, particularly when dealing with single-ended cable assemblies or coaxial cables with components, due to the need for destructive connectors and non-standard adapters.
Innovation Solution
An adapter with a quick self-locking structure and replaceable components, featuring a standard RF connector interface, allows for fast and damage-free connection of cables and cable assemblies, including those with components, by using a detachable design for the elastic clamping member and inner conductor, maintaining impedance consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If destructive connectors and non-standard adapters are used for testing, then testing capability is achieved, but cable damage and high costs occur
Solution Approach 1:
The patent introduces an adapter as an intermediary device between the testing equipment and the cable. The adapter includes a standard connector interface that connects to testing equipment and a clamping structure that securely holds the cable without damage. This intermediary solution enables testing capability while avoiding direct damage to the cable itself.
Solution Approach 2:
The adapter is divided into separate functional components: a standard connector portion for equipment interface and a clamping portion for cable securing. This segmentation allows the adapter to provide testing capability through the connector while the clamping structure protects the cable from damage during the testing process.
2Productivity
If quick self-locking structure is implemented, then connection speed is improved, but device complexity increases
Solution Approach 1:
The adapter employs a self-locking clamping structure that automatically secures the cable upon insertion without requiring additional manual operations. The elastic clamping portions naturally engage with the cable and lock into position through their elastic deformation, providing quick connection while maintaining a relatively simple overall structure.
Solution Approach 2:
The clamping structure utilizes elastic deformation dynamics to achieve quick self-locking. The elastic clamping portions can dynamically adjust their shape during insertion and automatically lock when they return to their elastic equilibrium position, providing fast connection without complex mechanical locking mechanisms.
