Solution Overview

Problem

Existing multi-pole connector sets inadequately suppress electromagnetic wave interference between inner terminals disposed in the same rows, despite effective suppression between different rows using shield members.

Innovation Solution

A multi-pole connector set design where a first connector with inner terminals in multiple rows is paired with a second connector, featuring a first shield member that connects to both sets of inner terminals, enhancing electromagnetic wave interference suppression by grounding and structural alignment of terminals.

Solution Approach 1:

The shield member is divided into multiple segments: first shield portions positioned between inner terminals in the same row, and second shield portions positioned between rows of inner terminals. This segmentation allows each portion to address specific interference patterns, with the first shield portions suppressing same-row interference and the second shield portions suppressing different-row interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the shield member are configured with different structures and positions to address local interference characteristics. The first shield portions are positioned adjacent to inner terminals in the same row to suppress local interference, while the second shield portions are positioned between rows to address inter-row interference, creating locally optimized shielding throughout the connector.
