Connector Termination Module Prevents Contact Arcing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High current provided to powered devices in telecommunications systems can cause arcing when the electrical connection between connectors is broken, damaging or degrading the performance of the connectors.
Innovation Solution
A connector with a termination module that includes a sensing module to detect the movement of a mating connector, providing a termination signal to the processing device to terminate the data or electrical connection before disconnection, thereby preventing arcing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high current is provided to powered devices, then power delivery capability is improved, but arcing occurs when connection is broken which damages connectors
Solution Approach 1:
The sensing module detects the removal motion of the mating connector and triggers the processing device to terminate current flow before the physical connection is broken. This preliminary termination of power prevents arcing from occurring when the high-current connection is disconnected, thus protecting the connectors from damage while maintaining high power delivery capability during normal operation.
2Object-affected harmful factors
If sensing module is added to detect connector removal, then arcing is prevented, but device complexity increases
Solution Approach 1:
The sensing module serves multiple functions: it detects the removal motion of the mating connector, triggers the termination of current flow, and enables the overall protection mechanism. By integrating these functions into a single module that works cooperatively with the processing device, the patent reduces the need for separate complex components while achieving reliable arcing prevention.
