USB Type-C Plug Connector Without Outer Iron Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB type-C electrical plug connectors have increased manufacturing time and cost due to their complex structure and the need for an outer iron shell, which is insufficient for meeting the higher bandwidth demands of modern devices.
Innovation Solution
An electrical plug connector design featuring an insulated housing without an outer iron shell, incorporating a semi-tubular or tubular structure with integrated plug terminals that can be mated with a Type-C receptacle connector for signal and power transmission, allowing for reduced terminal count and simplified manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an outer iron shell is used to enclose the insulated housing, then the structural strength and EMI shielding are improved, but the manufacturing time and cost increase
Solution Approach 1:
The patent removes the outer iron shell from the conventional USB Type-C connector structure, extracting only the essential insulated housing and plug terminals. This eliminates the need for complex multi-component assembly while maintaining the core functionality of signal and power transmission.
Solution Approach 2:
The patent integrates the insulated housing and plug terminals into a simplified unified structure. The insulated housing directly holds the plug terminals without requiring an additional outer shell, merging multiple components into a more compact and manufacturable design.
2Strength
If an outer iron shell is used to enclose the insulated housing, then the structural strength and EMI shielding are improved, but the manufacturing cost increases
Solution Approach 1:
The patent removes the outer iron shell from the conventional USB Type-C connector structure, extracting only the essential insulated housing and plug terminals. This eliminates the need for complex multi-component assembly while maintaining the core functionality of signal and power transmission.
Solution Approach 2:
The patent replaces expensive metal shell materials with a cost-effective insulated housing structure that achieves the required mechanical strength and EMI shielding through alternative design approaches, reducing material costs while maintaining functionality.
3Object-affected harmful factors
If multiple components (outer iron shell, insulated housing, plug terminals) are used, then the EMI shielding and structural integrity are improved, but the device complexity increases
Solution Approach 1:
The patent integrates the insulated housing and plug terminals into a simplified unified structure. The insulated housing directly holds the plug terminals without requiring an additional outer shell, merging multiple components into a more compact and manufacturable design.
Solution Approach 2:
The insulated housing serves multiple functions simultaneously: providing mechanical support, EMI shielding, and terminal positioning. This multi-functional design eliminates the need for separate specialized components, reducing overall structural complexity.

AI summary
An electrical plug connector includes an insulated housing and a plurality of plug terminals. The insulated housing includes a base portion and a semi-tubular portion extending from one side of the base portion. The semi-tubular portion includes a portion, a front stopping portion at a front lateral surface of the portion, and a plurality of side blocks extending outward from two sides of the portion. The plug terminals include a plurality of signal terminals, one or more power terminal, and one or more ground terminal. The plug terminals are held in the insulated housing and at the surface of the portion.
