Flat Cable Connector Layout for Stub-Free Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connectors suffer from deteriorated transmission characteristics due to the generation of stubs (signal branches) when connecting signal lines via contact members.
Innovation Solution
An electrical-connector-equipped cable design that exposes the distal end surfaces of conductors to the outside, reducing stub generation by direct connection, and uses a second dielectric with matched impedance to further improve transmission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal lines are connected via contact members in existing electrical connectors, then connection is achieved, but stubs (signal branches) are generated and transmission characteristics deteriorate
Solution Approach 1:
The patent extracts and eliminates the contact member from the signal transmission path. By providing openings in the connector body that directly expose the distal end portions of the conductors, the signal line connects directly to the connector without passing through contact members, thereby removing the source of stub generation and improving transmission characteristics
Solution Approach 2:
The patent introduces dielectric members as intermediaries to fill the spaces between the conductors and the connector wall. These dielectric members provide mechanical support and electrical insulation while allowing direct signal transmission from the conductors to the connector terminals, eliminating the need for contact members that caused stubs
2Reliability
If contact members are used to connect signal lines, then electrical connection is established, but transmission characteristics are deteriorated
Solution Approach 1:
The contact member is completely removed from the signal path. The connector body is designed with openings that allow direct exposure of conductor distal ends, eliminating the intermediate contact member that caused signal loss and improving overall transmission efficiency
Solution Approach 2:
The patent changes the structural parameters of the connector by creating openings in the connector body and positioning conductors to directly expose their distal end portions. This structural modification eliminates the contact member interface and reduces signal loss, improving transmission characteristics

AI summary
An electrical-connector-equipped cable includes a flat cable and a connector. The flat cable includes a plurality of conductors arranged side by side, and a first dielectric covering the plurality of conductors to expose a distal end portion of each of the plurality of conductors. The connector holds the distal end portion of each of the plurality of conductors to expose a distal end surface of each distal end portion to an outside. A first opening is provided in the connector. The first opening exposes the distal end portion of at least one first conductor of the plurality of conductors. The distal end portion of the first conductor is positioned in the first opening, and a second dielectric is provided between a wall defining the first opening and the first conductor.
