Communication Jack With Rotated Contacts For Six-Position Plugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication jacks face issues with plastic deformation and crosstalk when interfacing with six-position plugs due to the absence of plug contacts 1 and 8, leading to operational damage and compromised signal transfer.
Innovation Solution
The design incorporates front-rotated and back-rotated plug interface contacts with spring sections and compliant pins, which allow for greater deflection without deformation and reduce crosstalk by optimizing the electrical path and spacing between contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the jack is designed with standard rigid PICs for eight-position plugs, then it achieves proper signal transfer with eight-position plugs, but the outer PICs undergo excessive deflection and plastic deformation when six-position plugs are connected
Solution Approach 1:
The patent transforms rigid PICs into dynamic, flexible PICs with integrated spring sections that can deflect elastically rather than plastically. The spring section allows the PIC to dynamically adapt its position when a six-position plug is inserted, absorbing the extra deflection without permanent deformation, thus maintaining reliability across both plug types.
Solution Approach 2:
The patent changes the physical parameter of the PIC from rigid to flexible by incorporating a spring section with specific mechanical properties. This parameter change enables the PIC to withstand greater deflection forces when six-position plugs are connected, preventing plastic deformation while maintaining electrical contact reliability.
2Measurement precision
If the PIC arrangement is optimized for eight-position plugs, then signal transfer is optimal, but crosstalk increases when six-position plugs are connected due to altered electrical paths
Solution Approach 1:
The patent applies different structural qualities to different parts of the PIC system. The spring section is designed with specific local mechanical properties to control deflection characteristics, while the contact zone maintains precise electrical positioning. This local quality differentiation allows the system to maintain signal integrity while managing crosstalk under varying plug configurations.
