Plug Connector Guiding Wall Limiting Groove Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic connectors with limited installation space, the risk of pin collapse occurs due to the ease of oblique insertion and deformation of the plug, which can damage the circuit board and conductive terminals.
Innovation Solution
The design includes an insulating body with a limiting groove and guiding wall on the plug, and corresponding gaps in the socket, to guide and secure the plug's insertion, preventing shaking and oblique insertion, thus reducing the risk of pin collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the plug is made very short to fit limited installation space, then the installation space requirement is improved, but the plug becomes easy to bend and deform, increasing the risk of pin collapse
Solution Approach 1:
The guiding wall and limiting groove are designed to guide the plug insertion before the pins make contact with the terminals. This preliminary guiding action ensures proper alignment is established prior to the critical connection phase, preventing oblique insertion that could cause pin collapse even when the plug is short and flexible
Solution Approach 2:
The guiding wall acts as an intermediary element between the plug and the socket terminals. It mediates the insertion process by providing a guiding surface that directs the plug into proper alignment, reducing the direct impact of plug deformation on the connection reliability
2Volume of moving object
If the plug is made very short to fit limited installation space, then the installation space requirement is improved, but the plug is easy to be inserted obliquely, damaging the circuit board and conductive terminals
Solution Approach 1:
The guiding wall and limiting groove are designed to guide the plug insertion before the pins make contact with the terminals. This preliminary guiding action ensures proper alignment is established prior to the critical connection phase, preventing oblique insertion that could cause pin collapse even when the plug is short and flexible
Solution Approach 2:
The guiding wall acts as an intermediary element between the plug and the socket terminals. It mediates the insertion process by providing a guiding surface that directs the plug into proper alignment, reducing the direct impact of plug deformation on the connection reliability
3Reliability
If guiding structures are added to prevent oblique insertion, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The guiding wall is integrated into the insulating body of the socket, and the limiting groove is formed as part of the insulating body structure. This merging of guiding functions into the existing insulating body reduces the need for separate guiding components, thereby limiting the increase in device complexity while still providing reliable alignment
Solution Approach 2:
The insulating body serves multiple functions: electrical insulation, structural support, and insertion guidance. By making the insulating body multi-functional with integrated guiding walls and limiting grooves, the patent avoids adding dedicated guiding components, thus limiting the increase in device complexity
