Plug Connector With Elastic Encryption Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plug connectors lack the On-The-Go (OTG) function, preventing data transmission with mobile devices and the reading of encryption chips, limiting their usability with handheld computers and mobile phones.
Innovation Solution
A plug connector design featuring a dielectric body with a docking surface, a circuit board, and integrated first and second terminals, where the second terminal is elastically projected beyond the docking surface and soldered to the circuit board, enabling OTG functionality and allowing the reading of encryption chips, with simplified production processes and lower costs due to integral molding of all terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional plug connector design is used, then the structure is simple and production is easy, but the On-The-Go function is not available and encryption chips cannot be read
Solution Approach 1:
The patent combines multiple terminal functions into a single integrated terminal structure. The second terminal integrates both power transmission and encryption chip reading capabilities, eliminating the need for separate terminals for each function. This merging approach enables OTG functionality while maintaining relatively simple overall structure.
Solution Approach 2:
The second terminal is designed with multi-functionality, serving both as a power transmission terminal and as an encryption chip reading terminal. This universal design allows the connector to support OTG functions without adding excessive complexity, as one terminal performs multiple roles.
2Adaptability or versatility
If multiple separate terminals are used for different functions, then each terminal can be optimized for its specific function, but the production process becomes complex and assembling efficiency decreases
Solution Approach 1:
The patent merges multiple functional terminals into a single integrated terminal component. The second terminal combines power transmission and encryption chip reading functions, reducing the total number of separate components that need to be assembled. This integration directly improves assembling efficiency while maintaining full functionality.
3Adaptability or versatility
If multiple separate terminals are used for different functions, then each terminal can be optimized for its specific function, but the production cost increases
Solution Approach 1:
The patent combines multiple terminal functions into a single molded terminal component. This merging reduces the number of separate parts that need to be manufactured, assembled, and tested, thereby lowering production costs while maintaining all necessary functions including power transmission and encryption chip reading.
Solution Approach 2:
The second terminal is designed as a universal component that performs multiple functions (power transmission and encryption chip reading). This multi-functionality reduces the total component count and simplifies the bill of materials, leading to lower production costs compared to having separate specialized terminals for each function.

AI summary
A plug connector includes a dielectric body having a docking surface, a circuit board mounted to a rear of the dielectric body, a plurality of first terminals and a second terminal. The plurality of the first terminals are fastened to the dielectric body. Top surfaces of front ends of the plurality of the first terminals are exposed to the docking surface of the dielectric body. Rear ends of the plurality of the first terminals project beyond a rear surface of the dielectric body and are soldered to the circuit board. The second terminal is fastened to the dielectric body. A front end of the second terminal elastically projects beyond the docking surface of the dielectric body, and a rear end of the second terminal projects beyond the rear surface of the dielectric body and is soldered to the circuit board.
