USB Type-C Connector Structural Integration via Insert Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB type-C electrical plug connectors have insufficient structural strength due to the lack of adhesive bonding between plastic components, leading to potential detachment over time.
Innovation Solution
The design incorporates a metallic shell, an insulated housing with assembling portions, a grounding plate, and terminal modules, where the components are securely assembled using insert-molding techniques and elastic side arms providing spring force for secure mating with receptacle connectors, allowing dual orientation insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic components are combined by assembling without adhesives, then ease of manufacture is improved, but structural strength deteriorates
Solution Approach 1:
The patent merges multiple plastic components (upper housing, lower housing, and insulation core) into a single integrated structure through injection molding. This eliminates the need for separate assembly steps and adhesive bonding, thereby maintaining ease of manufacture while significantly improving structural strength and preventing component detachment over time.
2Device complexity
If multiple plastic components are assembled together, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The patent combines multiple plastic components into a single integrated housing structure formed by injection molding. This eliminates the need for separate assembly steps and adhesive bonding, thereby maintaining ease of manufacture while significantly improving structural strength and preventing component detachment over time.
3Ease of manufacture
If conventional assembling methods are used, then manufacturing process is simple, but connection stability deteriorates
Solution Approach 1:
The patent merges multiple plastic components (upper housing, lower housing, and insulation core) into a single integrated structure through injection molding. This eliminates the need for separate assembly steps and adhesive bonding, thereby maintaining ease of manufacture while significantly improving structural strength and preventing component detachment over time.

AI summary
An electrical plug connector includes a metallic shell, an insulated housing, a grounding plate, a first terminal module, a second terminal module, and a molding block. The first terminal module includes first plug terminals and a first combining block. The second terminal module includes second plug terminals and a second combining block. The insulated housing is received in the metallic shell. The first and the second combining blocks are respectively combined with the first plug terminals and the second plug terminals by insert-molding techniques. Then, the first combining block and the second combining block are respectively assembled to the grounding plate. Next, the molding block is provided to combine the first combining block with the second combining block, so that an assembly of the first terminal module, the second terminal module, and the grounding plate can be firmly assembled to the rear of the insulated housing.
