Connector Linear Displacement Guide for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors, particularly those for high-frequency signal transmission like RJ45 connectors, face challenges in forming reproducible electrical connections due to issues with contact security and assembly, leading to potential signal quality degradation.
Innovation Solution
A connector design that ensures linear displacement of the cable end device into the housing device, preventing pivoting or rotating movements, which applies force only along the insertion direction, thereby reducing bending of line contacts and enhancing contact reliability. This design includes a cable end device with line receptacles, a housing device with a cable termination receptacle, and a cover device that can be linearly displaced, ensuring secure and frictional contact without perpendicular forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable end device is inserted into the housing device without linear displacement constraints, then the assembly process is simpler, but the line contacts may bend and contact security deteriorates
Solution Approach 1:
Guide elements are introduced as intermediary components between the cable end device and housing device. These guide elements constrain the insertion movement to be purely linear, preventing pivoting and rotating movements that would cause line contact bending. The guide elements act as mediators that translate the assembly requirement into a controlled linear motion path.
Solution Approach 2:
The guide elements are pre-installed in the housing device before the cable end device is inserted. This preliminary arrangement ensures that the linear displacement constraint is already in place, guiding the cable end device along the correct path from the beginning of the insertion process, thereby preventing contact bending before it can occur.
2Manufacturing precision
If perpendicular forces act on the line contacts during assembly, then the assembly process is more flexible, but signal quality deteriorates due to contact bending
Solution Approach 1:
The guide elements serve as intermediaries that filter out perpendicular force components during assembly. By constraining the motion to linear displacement only, the guide elements prevent any force components perpendicular to the line contacts, thereby protecting signal quality while still allowing straightforward assembly operations.
3Reliability
If the cover device can be displaced in multiple directions relative to the housing device, then the cover device is easier to install, but the line contacts may be subjected to bending forces
Solution Approach 1:
Cover guide elements are introduced as intermediary components that constrain the cover device to linear displacement only relative to the housing device. These guide elements prevent multi-directional movement that would transmit bending forces to the line contacts, while still allowing simple straight-line installation of the cover device.

AI summary
The connector (1) has a line retainer (21) into which an electric line of a cable is inserted along a line introduction direction. An anode side (7a) is provided with a line contact aperture (25) that is connected to the line retainer. A cable final device (7) is inserted into a cable final device accommodator (23) in sections linearly along a direction of insertion (E). A conductive contact is formed by the insertion of the cable final device in the line contact aperture that is insertable in regions. An electrical lead is electrically contacted with the conductive contact. An independent claim is also included for a method for assembling a connector.
