Nested Multipolar Connector Layout for Low-Interference Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipolar connectors face challenges in suppressing inter-terminal interference, especially between high frequency and low frequency signal terminals, while also requiring a reduction in height to accommodate the size reduction and functionality enhancement of mobile devices.
Innovation Solution
The female multipolar connector design includes a first internal male terminal and a second internal female terminal, with a first external female terminal surrounding the first internal terminal. This configuration suppresses interference between the terminals and allows for a reduction in height, particularly by ensuring the first external terminal is taller than the first internal terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the height of the external terminal is reduced to meet size reduction requirements, then the connector height is reduced, but inter-terminal interference between high frequency and low frequency signal terminals increases
Solution Approach 1:
The patent applies nesting by placing the first internal terminal inside the first external terminal, and the second internal terminal inside the first external terminal. This nested arrangement allows the external terminal to maintain a greater height than the internal terminals, creating spatial separation that suppresses inter-terminal interference while keeping the overall connector height reduced.
Solution Approach 2:
The patent resolves the height contradiction by utilizing the radial dimension. The external terminal surrounds the internal terminals in the radial direction, allowing the external terminal to be taller in the axial direction without increasing the overall connector footprint. This dimensional approach enables interference suppression through height differential while maintaining compact overall dimensions.
2Volume of moving object
If the connector height is reduced for mobile device integration, then device size is reduced, but the ability to suppress interference between high frequency and low frequency terminals deteriorates
Solution Approach 1:
The nested configuration of internal terminals within the external terminal creates hierarchical spatial separation. The external terminal's greater height provides an interference suppression barrier for high frequency signals, while the nested structure maintains compact volume suitable for mobile devices.
Solution Approach 2:
The patent applies local quality by making the external terminal taller than the internal terminals specifically in the regions where interference suppression is needed. This localized height differentiation provides targeted interference protection for high frequency signals without requiring uniform height increases across all terminals.

AI summary
A female multipolar connector includes a first internal terminal; a second internal terminal; a first external terminal; and a first insulator that holds the first external terminal. The first internal terminal is a male type and is arranged on an inner side portion of the first external terminal. The second internal terminal is a female type and is arranged on an outer side portion of the first external terminal. A height of the first external terminal is greater than a height of the first internal terminal. The first external terminal is the female type.
