Electrical Connector Latch Mechanism Side Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing I/O connectors face challenges in achieving high-density, high-data-rate transmission while maintaining reliable latching mechanisms without increasing width, which affects signal integrity and manufacturing efficiency, and makes it difficult to operate multi-port connectors effectively.
Innovation Solution
An electrical connector assembly with a housing containing receiving rooms for printed circuit boards, a latch mechanism on the exterior, and a metallic holder shielding part of the latch mechanism, featuring a latching member and pulling member interconnected for easy operation, along with spacers and strain reliefs for electrical and mechanical support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the width of the electrical connector is increased to accommodate multiple ports, then the data transmitting rate is improved, but the ease of operation of the latch mechanism deteriorates
Solution Approach 1:
The patent positions the latch mechanism at the side of the connector housing rather than on the front face, utilizing the side dimension for operation. This allows the latch to be easily accessible and operable even when the connector width is increased to accommodate multiple ports for high data transmission rates.
2Quantity of substance
If the terminal arrangement is made more dense to increase connector density, then the compactness is improved, but the electrical separation between terminals deteriorates
Solution Approach 1:
The patent applies different structural characteristics to different regions of the connector. The housing includes positioning structures and reinforcement features at specific locations to maintain electrical separation and signal integrity in high-density terminal arrangements, while allowing overall compactness through optimized terminal layout.
3Manufacturing precision
If the tolerance of terminal locations is reduced to improve manufacturing precision, then the signal integrity is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent incorporates positioning structures and guide features in the housing that pre-establish accurate terminal locations during assembly. This preliminary positioning action ensures consistent terminal alignment and spacing without requiring extremely tight manufacturing tolerances on individual components, thereby improving manufacturability while maintaining signal integrity.
