Socket Spring Clip Indentation for Low-Abrasion Plug Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket bodies for electric plug-in connections suffer from high mechanical abrasion and geometrically undefined contact between the spring clip and the plug pin, leading to suboptimal contact properties and reduced plug-in cycles.
Innovation Solution
A socket body design featuring a spring clip with a single indentation on its edge, which provides defined contact points for improved electrical contact and reduces mechanical abrasion by interrupting the edge, thus allowing for more plug-in cycles with unchanged contact properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring clip protrudes into the socket space without indentation, then the socket body structure is simple, but the contact between spring clip and plug pin is geometrically undefined and mechanical abrasion is high
Solution Approach 1:
The invention applies local quality by introducing an indentation at a specific location on the spring clip edge. This local modification creates defined contact points without changing the overall spring clip structure, thereby improving contact properties while maintaining structural simplicity. The indentation is precisely positioned to achieve optimal contact geometry with the plug pin.
2Ease of manufacture
If the spring clip edge is continuous without indentation, then the manufacturing process is simple, but mechanical abrasion during plug-in operation is comparatively high
Solution Approach 1:
The invention applies segmentation by interrupting the continuous edge of the spring clip with an indentation. This segmentation divides the edge into distinct sections with defined contact points, reducing the contact area and thereby minimizing mechanical abrasion during plug-in operations while remaining compatible with standard manufacturing processes.
3Reliability
If multiple indentations are added to the spring clip, then contact points are increased, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The invention applies partial action by implementing a single strategically positioned indentation rather than multiple indentations. This single indentation creates sufficient defined contact points (two contact points on either side) to improve electric contact reliability, while avoiding the increased complexity and manufacturing difficulty that would result from multiple indentations.
