Solution Overview
Problem
Existing plug-in connectors for circuit boards often occupy excessive design space and lack stability, particularly under vibrational conditions, necessitating improved design to optimize space utilization and enhance mechanical fastening.
Innovation Solution
A U-shaped or double U-shaped plug-in connector design with a fastening arm or shield plate, featuring a U-shaped inner conductor, insulating part, and U-shaped or double U-shaped outer conductor, which includes fastening means for secure attachment to the circuit board, reducing design height and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plug-in connector designs are used, then electrical connection functionality is achieved, but excessive design space is occupied and stability under vibration is insufficient
Solution Approach 1:
The connector components are nested within each other, with the contact element positioned inside the housing structure, and the fastening element integrated into the overall assembly. This nesting arrangement allows multiple functional elements to occupy overlapping or adjacent spaces, reducing the total design space required while maintaining structural integrity and vibration resistance
Solution Approach 2:
The connector design transitions from a planar two-dimensional layout to a three-dimensional configuration by utilizing vertical space and angular orientations. The contact element and fastening element are arranged in different spatial planes and angles, allowing compact packaging that reduces overall footprint while maintaining functional performance and stability
2Volume of moving object
If connector components are arranged to reduce design height, then space utilization improves, but mechanical fastening stability may be compromised
Solution Approach 1:
The connector employs asymmetric arrangement of components, with the fastening element positioned at an angle relative to the contact element. This asymmetric configuration optimizes the distribution of mechanical stresses and allows the fastening element to engage more effectively with the circuit board, maintaining strong mechanical attachment while minimizing the vertical profile of the assembly
Solution Approach 2:
The connector is divided into distinct functional segments - the contact element for electrical connection and the fastening element for mechanical attachment. This segmentation allows each component to be optimized independently for its specific function, enabling compact overall design while ensuring the fastening element maintains adequate strength and stability
