Connector Coupling Structure for Low-Force Through-Hole Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors require high insertion force for positioning the conductor connection portion with respect to the through-hole, making it difficult to facilitate easy alignment and assembly.
Innovation Solution
A connector design featuring a terminal fitting with an elastically deformable coupling portion that applies resilient forces to guide the conductor connection portion into alignment with the through-hole, allowing for simple positioning and reduced insertion force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the fixing portion is press-fitted into the accommodating chamber without elastic deformation, then the positioning between the conductor connection portion and the through-hole is achieved, but the insertion force required increases
Solution Approach 1:
The connecting portion is designed to be elastically deformable, changing its physical state from rigid to flexible during the insertion process. This allows the connecting portion to deform elastically under insertion force, enabling the conductor connection portion to be positioned accurately in the through-hole with reduced insertion force compared to rigid press-fitting
Solution Approach 2:
The connecting portion transitions from a static rigid structure to a dynamic elastically deformable structure. During assembly, the connecting portion deforms elastically to accommodate the insertion process, then returns to its original shape to maintain positioning, making the system adaptive rather than fixed
