Solution Overview

Problem

Existing USB Type-C electrical connectors are large in size, which is a drawback for compact designs and applications.

Innovation Solution

The design incorporates an insulating housing with first and second terminals, each with differential signal, power, and grounding terminals, arranged in a specific configuration within a shielding shell to allow for a smaller form factor while maintaining 180-degree symmetry for bidirectional mating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminals are arranged in separate rows at opposite sides of the tongue board, then the bidirectional mating capability is achieved, but the dimension of the receptacle connector becomes large

Engineering Contradiction:

Improvebidirectional mating capabilityVSAvoiddimension of the receptacle connector

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent merges the connecting legs of power terminals and grounding terminals into the middle area of the mounting surface, while differential signal terminals are positioned at opposite sides. This consolidation reduces the overall connector dimension while preserving bidirectional mating capability through symmetric arrangement of signal terminals.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a traditional horizontal row arrangement of all terminals to a vertical arrangement where connecting legs extend in the front-to-back direction from the mounting surface. This dimensional reorganization allows compact footprint while maintaining functional separation of terminal types.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the connecting legs are arranged in separate rows, then the signal transmission reliability is improved, but the connector size increases

Engineering Contradiction:

Improvesignal transmission reliabilityVSAvoidconnector size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent assigns different spatial zones within the compact connector volume to different terminal functions: the middle area houses power and grounding terminals for stable reference, while differential signal terminals occupy opposite sides for balanced signal transmission. This localized functional distribution maintains signal integrity within reduced dimensions.

Inventive Principle:

Principle #3Local quality

AI summary

An electrical connector includes an insulating housing, first terminals, second terminals and a shielding shell. The insulating housing has a base portion and a mating portion, and the base portion has a mounting surface. The first terminals have a pair of differential signal terminals, a power terminal, and a grounding terminal, and the second terminals having the same type of terminals. The power terminal and the grounding terminal are disposed at two opposite sides of the pair of differential signal terminals, respectively. The first terminals and the second terminals have connecting legs extending out of the mounting face. The connecting legs of the power terminals and the grounding terminals are disposed at the middle area of the mounting surface, and the connecting legs of the differential signal terminals are respectively disposed at two opposite sides of the connecting legs of the power terminals and the grounding terminals.
