USB Type-C Receptacle Terminal Alignment for Solder Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB Type-C electrical receptacle connectors make it difficult for operators to verify if the inner tail portions are firmly soldered to a circuit board due to shielding by outer tail portions, hindering convenient inspection and potentially leading to unreliable connections.
Innovation Solution
The electrical receptacle connector design aligns the tail portions of both upper-row and lower-row receptacle terminals into a line, allowing for easy verification of soldering and incorporating a dual orientation design with flat contact portions aligned in two rows, enabling intuitive mating orientations and reducing the length and space occupied by the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the tail portions of receptacle terminals are arranged in multiple rows for compact layout, then the connector structure is more compact, but the inner tail portions are shielded by outer tail portions making soldering inspection difficult
Solution Approach 1:
The patent transitions the tail portion arrangement from a two-dimensional multi-row layout to a one-dimensional linear arrangement. By aligning all tail portions in a single line, the patent eliminates the shielding effect that occurs in multi-row configurations while maintaining compactness through the linear organization of terminals.
2Difficulty of detecting and measuring
If the tail portions are aligned into a line for easy inspection, then soldering verification is convenient, but the connector occupies more space
Solution Approach 1:
The patent merges the tail portions of multiple receptacle terminals into a single linear arrangement. By combining what would traditionally be distributed across multiple rows into one unified line, the patent achieves both inspection convenience and space efficiency through the consolidated layout.

AI summary
An electrical receptacle connector includes an insulated housing, a plurality of upper-row receptacle terminals, and a plurality of lower-row receptacle terminals. The insulated housing includes a base portion. Each of the upper-row receptacle terminals includes a tail portion protruded from the base portion. Each of the lower-row receptacle terminals includes a tail portion protruded from the base portion. The tail portions of the upper-row receptacle terminals and the tail portions of the lower-row receptacle terminals are protruded from the base portion, aligned into a line, and spaced from each other.
