Twisted Pair Connector Housing Guide Maintaining Wire Twist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plug connectors for twisted pair cables are costly due to the need for integrated shielding to protect against external interference, which increases production costs and eliminates the use of low-cost, electrically insulating plastic housing materials.
Innovation Solution
The system maintains the twisting of the twisted pair cable within the plug connector housing, eliminating the need for shielding by continuing the wire twisting inside the connector, which guides the wires and fixes their position, ensuring electrical properties are preserved without additional shielding, allowing the housing to be made of inexpensive electrically insulating plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielding is integrated into the connector housing to protect against external interference, then the resistance to external interference is improved, but the manufacturing cost increases and the use of electrically insulating plastic is eliminated
Solution Approach 1:
The invention extracts the shielding function from the housing material selection and implements it through the geometric arrangement of conductors. By removing the need for shielded housing material, cost-effective electrically insulating plastic can be used while maintaining interference resistance through the twisted-pair conductor configuration alone
Solution Approach 2:
The invention replaces the mechanical/electrical shielding system (metal shielding layers) with a geometric arrangement system (twisted-pair conductor positioning). The twisting geometry itself provides the interference rejection without requiring additional shielding materials or structures
2Object-affected harmful factors
If shielding is integrated into the connector housing to protect against external interference, then the resistance to external interference is improved, but the housing material options are reduced to non-plastic materials
Solution Approach 1:
The shielding function is extracted from the housing material requirements and implemented through conductor geometry alone, allowing the housing to be made from any suitable material including electrically insulating plastics without compromising interference resistance
Solution Approach 2:
The invention changes the parameter of interference protection from material-based (conductive shielding layers) to geometry-based (twisted-pair arrangement). This parameter change enables the use of electrically insulating plastic materials that would otherwise be unsuitable for shielded applications
3Ease of operation
If the conductors are routed parallel within the connector housing, then the ease of connection is improved, but the resistance to external interference deteriorates
Solution Approach 1:
The conductor twisting is maintained continuously from the cable through the connector housing to the contact elements, ensuring interference protection is established before the conductors enter the connector and is maintained throughout the connection process
Solution Approach 2:
The twisting geometry is maintained continuously throughout the entire conductor path including within the connector housing, ensuring uninterrupted interference rejection. The guide structure ensures the twisting action continues effectively from the cable through the connector without interruption or unraveling
