Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB type-C electrical receptacle connectors are limited in usage and application due to their laid configuration, which restricts their assembly and mating with electronic devices, preventing a standing-type assembly and usage.
Innovation Solution
A standing-type electrical receptacle connector design featuring a metallic shell, insulated housing with specific terminal arrangements and bending structures, allowing for a standing assembly on a circuit board and dual orientation compatibility, with first and second receptacle terminals having increasing body lengths and symmetrical pin assignments for enhanced high-frequency characteristics and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional USB type-C electrical receptacle connector uses a laid configuration, then it can be easily manufactured and assembled on a circuit board, but its usage and application are restricted and it cannot be assembled in a standing manner
Solution Approach 1:
The patent transitions the connector from a traditional laid-flat configuration to a standing-up configuration by changing the spatial orientation dimension. The receptacle connector is designed to stand perpendicular to the circuit board surface, utilizing the vertical dimension rather than only the horizontal plane, thereby enabling multiple assembly orientations and improving adaptability without significantly increasing structural complexity
Solution Approach 2:
The connector design incorporates universal features that allow it to function in multiple orientations (standing and laid configurations). The symmetrical arrangement of contact terminals and the modular structure enable the same connector design to be used in different assembly scenarios, enhancing versatility while maintaining manufacturing simplicity
2Reliability
If the body portions of receptacle terminals have gradually increased lengths, then high-frequency characteristics are improved, but the terminal structure becomes more complex
Solution Approach 1:
The patent applies local quality by varying the length of terminal body portions specifically in the high-frequency signal transmission areas. Only certain terminal bodies have gradually increased lengths optimized for high-frequency performance, while other terminals maintain standard lengths. This localized optimization improves high-frequency characteristics without unnecessarily complicating the entire terminal structure
Solution Approach 2:
The patent changes the physical parameter of terminal body length to optimize high-frequency performance. By adjusting the length parameter of specific terminal bodies, the electrical characteristics for high-frequency signals are improved. This parameter modification is applied selectively rather than uniformly, balancing performance improvement with structural simplicity

AI summary
A standing-type electrical receptacle connector includes a metallic shell, an insulated housing, a plurality of first receptacle terminals, and a plurality of second receptacle terminals. The insulated housing received in the metallic shell is assembled with the first receptacle terminals and the second receptacle terminals. The first receptacle terminals and the second receptacle terminals are respectively held at two sides of the insulated housing along a width direction of the insulated housing, and the length of each of the body portions of the receptacle terminals gradually increases along the width direction of the insulated housing. The tail portions are extending out of the insulated housing and soldered on a circuit board. Accordingly, the standing-type electrical receptacle connector can be assembled to the circuit board in a standing manner.
