Fan Frame PIN Connector Layout for Automated PCB Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan frame assemblies face challenges with flexible wires being difficult to fix in shape, prone to welding dislocation, and requiring manual wire connection for testing, which complicates automatic assembly and affects production quality.
Innovation Solution
A fan frame design featuring a frame body with embedded PIN needles and an outlet body, allowing for automatic assembly and testing, with a compact structure and flexible PIN needle arrangement to improve welding accuracy and prevent sealing-off, and facilitating connection to a test fixture for automated testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible wires are directly welded on a circuit board, then wire connection is achieved, but welding dislocation and sealing-off occur under stress
Solution Approach 1:
The patent introduces a rigid PIN needle as an intermediary component between the wire and circuit board. The PIN needle replaces direct wire-to-board welding with a standardized connection interface that has fixed positioning features, eliminating welding dislocation and sealing-off issues while maintaining electrical connection reliability
Solution Approach 2:
The patent changes the physical state of the connection component from flexible wire to rigid PIN needle. This parameter change provides structural stability and prevents deformation under stress, thereby eliminating welding-related defects while enabling automated assembly through standardized interfaces
2Ease of operation
If manual wire connection is used for testing, then wire connection is achieved, but testing operation becomes complicated and time-consuming
Solution Approach 1:
The patent uses the PIN needle connection interface as a standardized template that can be replicated across multiple testing scenarios. The same rigid connector structure used in assembly serves as the connection interface for testing, eliminating the need for separate manual wire connection procedures and enabling automated test fixture integration
Solution Approach 2:
The PIN needle connector serves multiple functions: it provides both the electrical connection for product assembly and the connection interface for testing operations. This multi-functionality eliminates the need for separate testing wiring procedures, simplifying operations and reducing testing time
