Modular Connector for Ribbon Cable Noise Reduction
Solution Overview
Problem
Industrial control and monitoring networks face challenges in reliably establishing connections, maintaining network continuity, providing additional power, and mitigating noise interference due to the simultaneous transmission of power and data on the same cable.
Innovation Solution
A modular connector system with a lower body and upper body design that includes orientation keys, insulation displacement members, and movable conductor severing devices, allowing for secure connection and separation of power and data conductors, while minimizing noise interference through strategic conductor positioning and crimping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power and data are transmitted on the same cable, then network functionality is enhanced, but noise interference between conductors increases
Solution Approach 1:
The cable is segmented into separate power conductors and data conductors within the same cable assembly, with distinct positioning and insulation. The connector separates power contacts and data contacts into different regions, reducing electromagnetic interference while maintaining integrated cable functionality.
Solution Approach 2:
Different regions of the cable and connector are assigned different functional qualities: power conductors are positioned and insulated differently from data conductors. The cable assembly includes localized shielding and positioning features specifically for power conductors versus data conductors to mitigate noise.
2Productivity
If devices are quickly connected and disconnected from the network, then installation flexibility is improved, but maintaining electrical continuity becomes more difficult
Solution Approach 1:
The connector is pre-assembled with the cable and insulation displacement contacts before field installation. The cable is pre-terminated with the connector housing, so that when the connector is plugged into the device, electrical continuity is immediately established without requiring additional field assembly steps that could compromise reliability.
Solution Approach 2:
The insulation displacement contacts automatically pierce and contact the conductors when the connector is mated to the device, establishing electrical continuity without requiring manual wire stripping or connection steps. The spring-loaded contacts maintain continuous pressure to ensure reliable electrical connection throughout operation.
3Adaptability or versatility
If additional power is supplied to installed networks, then network adaptability is improved, but connector complexity increases
Solution Approach 1:
The connector is designed to handle multiple functions through a standardized interface: it can connect power conductors, data conductors, and optional additional power conductors through the same basic connector housing and contact structure. The cable assembly can be configured with different conductor arrangements while using the same connector type, reducing the need for multiple specialized connector designs.
