SATA Connector Assembly with Exposed PCB Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SATA connector assemblies face difficulties in inspecting the fastening of the PCB and FFC, and they have limited maximum current capacity due to restricted electrical connections.
Innovation Solution
The design includes an insulating housing with terminal holes, a vertically secured PCB with multiple soldering holes and contacts on its rear surface, and a flex flat cable with exposed conductors connected to these contacts, allowing for easy assembly and inspection, and increasing the number of contacts to enhance current capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the PCB and FFC are internally connected within the housing, then the assembly is compact, but the inspection of fastening and electrical connection becomes difficult
Solution Approach 1:
The patent extracts the contacts from the internal structure and exposes them on the outer surface of the housing. This allows the contacts to remain part of the compact assembly while enabling easy visual inspection of both the fastening and electrical connection without disassembling the housing.
2Ease of manufacture
If the number of soldering holes is limited, then the manufacturing is simpler, but the maximum current capacity is restricted
Solution Approach 1:
The patent distributes multiple soldering holes across different surfaces of the PCB, including the rear surface. This spatial arrangement allows increasing the total number of soldering holes and corresponding contacts without significantly complicating the manufacturing process, thereby increasing the maximum current capacity while maintaining manufacturing simplicity.
