Electrical Connector Assembly With Metal Plate Tab Confinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies face challenges in securely fixing the connector to the housing while maintaining high shielding performance and water-tightness, especially under external forces.
Innovation Solution
The electrical connector assembly incorporates a housing with a hole featuring a stepped design, where the outer conductor with multiple tabs is securely confined by a metal plate and welded to the housing, ensuring reliable fixation and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is fixed to the housing using conventional methods, then the assembly is simple to manufacture, but the connection reliability and shielding performance deteriorate under external forces
Solution Approach 1:
The hole in the housing base is divided into two distinct parts: a first part with a first diameter for receiving the outer conductor, and a second part with a second diameter for receiving and confining the tabs. This segmentation allows each part to serve its specific function optimally, improving connection reliability while maintaining manufacturing simplicity.
Solution Approach 2:
The metal plate acts as an intermediary component between the tabs and the housing. It confines the tabs within the second part of the hole and provides a welding surface, thereby enhancing connection reliability and shielding performance without significantly increasing assembly complexity.
2Reliability
If the outer conductor is inserted through a simple hole, then the assembly process is simple, but the shielding performance and water-tightness deteriorate
Solution Approach 1:
The hole is segmented into two parts with different diameters. The first part (smaller diameter) receives the outer conductor, while the second part (larger diameter) accommodates the tabs and metal plate. This segmentation enables effective shielding and water-tightness without complicating the manufacturing process.
Solution Approach 2:
Different regions of the hole are given different qualities: the first part provides a tight fit for the outer conductor to ensure shielding, while the second part provides space for tab confinement and metal plate attachment to ensure water-tightness. This local differentiation achieves high shielding performance and ease of manufacture simultaneously.
3Strength
If the tabs are not confined, then the assembly structure is simple, but the connection strength and stability deteriorate under external forces
Solution Approach 1:
The metal plate serves as an intermediary that confines the tabs within the second part of the hole. This confinement significantly enhances connection strength and stability under external forces, while the overall structural complexity remains manageable due to the straightforward implementation.
Solution Approach 2:
The solution adds a dimensional element by introducing the metal plate that spans across the second part of the hole, creating a new structural dimension for tab confinement. This enhances connection strength without excessively increasing structural complexity.
