Insulative Shield Waterproof USB Type-C Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB Type C connectors with metallic shells face issues such as inferior waterproofing, shielding, and potential electrical interference or shorting due to seams and dust contact.
Innovation Solution
An electrical connector with a terminal module enclosed within an insulative shield featuring a rear mounting standing part, a front mating tongue part, and a pair of mounting legs, which provides a locking mechanism and improved retention on a PCB using a combination of insulative and metallic components for enhanced stability and water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metallic shell is used for the connector, then structural strength is improved, but waterproofing performance deteriorates due to seams
Solution Approach 1:
The patent uses an insulative material (such as plastic or polymer) to form the shell instead of metallic material. This insulative shell provides both sufficient structural strength and inherent waterproofing properties without seams, resolving the contradiction between strength and waterproofing performance.
2Object-affected harmful factors
If a metallic shield is used, then shielding effect is improved, but electrical interference with antenna increases
Solution Approach 1:
The patent replaces the metallic shield with an insulative shell that provides adequate protection without causing electrical interference. The insulative material naturally prevents electrical coupling between the shield and antenna, eliminating the harmful electrical interference while maintaining sufficient shielding effect.
3Object-affected harmful factors
If a metallic shield is used, then shielding effect is improved, but risk of shorting increases due to dust contact
Solution Approach 1:
The patent uses an insulative shell instead of a metallic shield. The insulative material prevents electrical conduction between the shell and other electronic components even when dust particles bridge the gaps, thereby eliminating the shorting risk while maintaining shielding effectiveness.
4Ease of manufacture
If sheet metal is used to form the metallic exterior shield, then ease of manufacture is improved, but waterproof character deteriorates
Solution Approach 1:
The patent employs an insulative shell made from molded material (such as injection-molded plastic) that can be manufactured easily while providing seamless construction. This molding process allows for complex shapes and integrated features without requiring assembly of multiple metal sheets, thus maintaining ease of manufacture while achieving superior waterproof character.

AI summary
An electrical connector with a terminal module enclosed within an insulative shield wherein the terminal module includes a plurality of terminals embedded within an insulative main body. The insulative main body forms a rear mounting standing part and a front mating tongue part extending forwardly from the rear mounting standing part. The insulative shield forms a rearward step against a forward shoulder of the base portion so as to prevent further forward movement of the base portion relative to the insulative shield. The insulative main body forms a protrusion and the insulative shield forms a securing hole to receive said protrusion for securing the insulative shield and the terminal module together.
