Connector Terminal Positioning to Prevent Contact Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors face issues where the first contact part of the terminal is wound up when the second connector is inclined relative to the first connector during disengagement, leading to deformation or breakage of the overhanging part due to insufficient resistance against upward forces.
Innovation Solution
The connector design includes a first terminal with a linear contact part and a termination part, where the second terminal's contact part is positioned ahead of the first terminal's contact part in the insertion direction, preventing the first contact part from being wound up by allowing smooth sliding contact during oblique removal, and featuring a J-shaped or curved contact part with an overhanging part for additional resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second connector is raised relative to the first connector during disengagement, then the connectors can be separated, but the first contact part may be dragged and wound up by the rising second contact part
Solution Approach 1:
The patent applies preliminary action by positioning the overhanging part of the first housing to preemptively block the first contact part before disengagement occurs. This preventive positioning ensures that when the second connector is raised during normal use, the contact part cannot be dragged upward, thereby preventing winding up and maintaining reliability while allowing easy disengagement
2Ease of operation
If force is applied that inclines the first connector and second connector with respect to one another during disengagement, then the connectors can be separated, but the first contact part is subjected to very large upward force causing the overhanging part to deform or break
Solution Approach 1:
The patent applies preliminary anti-action by designing the overhanging part to extend in the width direction and overlap the first contact part from above, creating a counteracting force that prevents the contact part from moving upward during inclined disengagement. This structural arrangement provides resistance against the upward force before it can cause deformation or breakage, while still allowing the connectors to be separated when needed

AI summary
A first contact part of a first terminal includes a linear part extending linearly in an insertion direction of an insertion protrusion, and a termination part of the linear part; and a first contact part of a second terminal includes a linear part extending linearly in an insertion direction of an insertion protrusion, and a termination part of the linear part; where, when an insertion protrusion is inserted into an insertion recess such that a first connector and a second connector achieve a completely mated state, the termination part of the linear part of the first contact part of the second terminal is positioned more in front of the insertion direction of the insertion protrusion than the termination part of the linear part of the first contact part of the first terminal.
