Electrical Connector Assembly With Extra Tongue Plates and Secure Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies lack the functionality to meet complex transmission requirements, particularly in terms of expanded functionality and secure mating retention.
Innovation Solution
The electrical connector assembly includes an insulating body with additional tongue plates, conductive terminals with exposed mating portions, and cables connected to these terminals, along with a mating connector featuring elastic arms and a metal shell for enhanced retention and foolproof alignment, allowing for increased transmission capabilities and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional tongue plates and conductive terminals are added to expand functionality, then transmission capabilities are enhanced, but device complexity increases
Solution Approach 1:
The connector is divided into modular components including main tongue plates, additional tongue plates, conductive terminals, and insulating bodies. Each component can be independently manufactured and assembled, allowing functionality to be expanded through addition rather than redesign of the entire system.
Solution Approach 2:
The additional tongue plates and conductive terminals are designed to perform multiple functions: they provide extended transmission capabilities while maintaining compatibility with existing connector structures. The same basic design principles apply to both standard and additional components, reducing overall system complexity.
2Reliability
If elastic mating arms are used to improve retention force, then mating reliability is enhanced, but manufacturing complexity increases
Solution Approach 1:
The elastic mating arms are integrated directly into the insulating body as a unified structure rather than being separate components. This merging of functions allows the retention mechanism to be formed during the insulating body manufacturing process, reducing assembly steps while maintaining reliable mating retention.
3Reliability
If positioning plates and wall portions are added for foolproof alignment, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The positioning plates and wall portions are designed with asymmetric features that provide foolproof alignment in specific directions. The positioning plates extend beyond the tongue plates in predetermined orientations, creating unique geometric relationships that guide proper connector insertion while preventing misalignment.
