Solution Overview

Problem

Conventional cable connection systems for high-speed signals face signal loss and complex, costly structures, especially when dealing with bundled cables on complex PCBs, which can lead to connectivity issues and increased risk of cables falling off.

Innovation Solution

A cable connection apparatus featuring a back plate with a ground layer and shielding holes, combined with a connection member and signal pin, which reduces signal loss by using a rounded signal pin and air flow, and a fixing member to secure cables, simplifying the structure and reducing manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional plugging mechanisms are used for cable connection, then the cable can be connected to the PCB, but the structure becomes complicated and manufacturing cost increases

Engineering Contradiction:

Improvecable connection reliabilityVSAvoidplugging mechanism structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connection system is divided into separate components: a connection member with signal pins that interfaces with the PCB, and a back plate with shielding holes that provides electromagnetic shielding. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining connection reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electromagnetic shielding function is extracted from the complex plugging mechanism and implemented through a separate back plate with shielding holes. This extraction eliminates the need for integrated shielding structures within the connector itself, reducing structural complexity while preserving signal integrity.
