Connector Terminal Blocking Structure for Stable Contact Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive terminals in wire-terminal connectors lack a fixing structure within the insulative housing, leading to displacement and poor conductivity during assembly and mating of connectors.
Innovation Solution
A conductive terminal with a blocking portion that engages with the insulative housing to constrain movement in longitudinal and perpendicular directions, preventing skewing and ensuring proper alignment and contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no fixing structure is provided between the conductive terminal and the insulative housing, then the device complexity is reduced, but the conductive terminal becomes subject to displacement and skewing, leading to poor conductivity
Solution Approach 1:
The conductive terminal is divided into distinct functional portions: a blocking portion for engagement with the insulative housing, a mating portion for electrical connection, and a crimping portion for wire attachment. This segmentation allows the blocking portion to specifically address the fixation problem without complicating the overall device structure.
Solution Approach 2:
The blocking portion acts as an intermediary element between the conductive terminal and the insulative housing. It provides a dedicated engagement interface that prevents displacement and skewing, ensuring reliable conductivity without requiring complex fixing structures throughout the entire assembly.
2Reliability
If a blocking portion is added to the conductive terminal to prevent displacement, then the reliability and conductivity are improved, but the device complexity increases
Solution Approach 1:
The blocking portion is integrated into the conductive terminal as a unified structure rather than being a separate component. This merging approach maintains reliability by ensuring the blocking portion remains firmly attached to the terminal while avoiding the complexity of additional assembly steps for separate fixing structures.
Solution Approach 2:
The blocking portion is strategically positioned at a specific location on the conductive terminal where it is needed for engagement with the insulative housing. This localized approach addresses the displacement problem only where necessary, without adding unnecessary complexity to other parts of the terminal structure.

AI summary
A conductive terminal adapted to be installed in an insulative housing of a connector comprises a mating portion located at a front of the terminal for engaging with a terminal of a mating connector, and a crimping portion located at a rear of the terminal for crimping to a wire. A blocking portion of the terminal is located between the mating portion and the crimping portion and engages with the insulative housing to constrain the movement of the conductive terminal in the housing in a longitudinal direction and in a direction perpendicular to the longitudinal direction.
