Floating Plug-Receptacle Connector Assembly for Mating Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board-to-board electrical connectors face issues with improper alignment during mating, leading to instability and reduced flexibility in circuit board layout due to fixed orientations.
Innovation Solution
The electrical connector assembly features plug and receptacle connectors with movable housings and terminals that allow for floating connections, enabling stable mating and increased flexibility through elastic terminals and hold-down members to absorb stress and prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the plug connector is fixed in a fixed state after mating, then the connection stability is improved, but the alignment flexibility is reduced
Solution Approach 1:
The plug connector transitions from a fixed state before mating to a fixed state after mating, with the housing providing guidance during the transition. The terminal positioning grooves and corresponding positioning structures enable automatic alignment during insertion, allowing the connector to adapt to alignment variations while achieving stable connection after mating.
Solution Approach 2:
The connector is divided into separate components: housing, terminals, and positioning structures. The terminal positioning grooves in the housing and corresponding positioning structures on the terminals work together to provide alignment guidance, separating the alignment function from the connection function to resolve the contradiction between stability and flexibility.
2Reliability
If the plug connector cannot be moved freely after mating, then the connection reliability is improved, but the adjustment capability is reduced
Solution Approach 1:
The terminal positioning grooves and positioning structures are pre-configured in the housing and terminals respectively, enabling automatic alignment guidance during insertion. This preliminary alignment mechanism ensures that the connector achieves correct positioning automatically during mating, improving reliability without requiring manual adjustment.
3Manufacturing precision
If the terminal positioning grooves are provided in the housing, then the terminal positioning precision is improved, but the device complexity is increased
Solution Approach 1:
The terminal positioning grooves are integrated into the housing structure, combining the positioning function with the existing housing component. This merging approach provides precise terminal positioning without adding separate positioning devices, thereby improving positioning precision while minimizing the increase in device complexity.
