Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp spring is used to prevent the second connector from coming out of the first connector, then the reliability of connection is improved, but the insertion force required to plug the connectors together increases
Solution Approach 1:
The clamp spring is designed with non-uniform cross-sectional dimensions, where the stressed portion has a smaller cross-sectional size than the rest portion. This local variation in geometry concentrates the deformation in a specific region, allowing the spring to flex more easily during insertion while maintaining its clamping function for reliable connection prevention.
Solution Approach 2:
The cross-sectional dimensions of the clamp spring are varied along its length, creating a stressed portion with reduced cross-sectional size. This parameter change enables the spring to undergo elastic deformation more readily during the plugging process, reducing the insertion force required while still providing sufficient clamping force to prevent disconnection.
2Ease of manufacture
If the clamp spring is made with uniform cross-sectional size, then the manufacturing simplicity is improved, but the ease of operation during insertion deteriorates
Solution Approach 1:
Instead of a uniform cross-section throughout, the clamp spring incorporates a localized stressed portion with reduced cross-sectional dimensions. This local modification creates a specific deformation zone that facilitates easier insertion while the rest of the spring maintains its structural integrity and clamping capability.
Solution Approach 2:
The clamp spring is functionally segmented into different regions: a stressed portion for elastic deformation during insertion, and a rest portion for maintaining structural strength and clamping force. This segmentation allows each region to be optimized for its specific function, improving ease of operation while maintaining manufacturing feasibility.

AI summary
The present disclosure relates to the technology of equipment parts, and in particular to a quick plug connector assembly. The quick plug connector assembly includes a first connector, a second connector, and a clamp spring, where the second connector has a plug-in part plugged into the first connector; the clamp spring is disposed on the first connector; the clamp spring includes a limiting section and a connecting section located at an end of the limiting section; a side wall of the first connector is provided with a gap; an outer peripheral surface of the plug-in part is provided with a first annular groove facing the gap; the limiting section passes through the gap and is stuck into the first annular groove; the connecting section is provided with a stressed portion, and the cross-sectional size of the stressed portion is smaller than that of the rest of the clamp spring. In the process of plugging the plug-in part, the plug-in part is easy to push against the limiting section of the clamp spring to make stressed portion of the clamp spring elastically deformed, and the resistance of the clamp spring to the plug-in part is reduced, thereby reducing the insertion force required for plugging the second connector in the plugging process, and facilitating the operator to plug the plug-in part of the second connector into the first connector.
