Electrical Connector Terminal Fixing Wings for Stable Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from instability of terminals due to lack of a fixing structure, leading to shaking during mating with a connector under external forces.
Innovation Solution
The electrical connector features a design with fixing wings on the conductive terminals that fit into corresponding slots in the insulative housing, along with an elastic fixing arm and terminal position assurance members to secure the terminals in place, preventing movement along the up-down direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no fixing structure is provided for the terminal, then the device complexity is reduced, but the terminal stability deteriorates causing shaking during mating
Solution Approach 1:
The terminal is segmented into distinct functional portions: a fixing portion with fixing wings for securing to the insulative housing, a mating portion for electrical connection, and a crimping portion for wire attachment. This segmentation allows each portion to be optimized for its specific function, with the fixing wings providing dedicated stabilization without complicating the overall device structure.
Solution Approach 2:
The fixing wings of the terminal are nested within corresponding fixing slots formed in the insulative housing. This nesting arrangement secures the terminal in place while maintaining a compact integrated structure, preventing shaking during mating operations without requiring additional external fixing components.
2Stability of the object's composition
If fixing wings are added to the terminal, then the terminal stability is improved, but the device complexity increases
Solution Approach 1:
The fixing wings are merged into the terminal body as an integrated feature rather than separate components. The insulative housing's fixing slots are similarly integrated into the housing structure. This merging approach provides effective terminal fixation while avoiding the complexity of additional separate fixing mechanisms.
Solution Approach 2:
The fixing portion of the terminal serves multiple functions: it secures the terminal to the insulative housing through the fixing slots, provides structural support for the mating portion, and maintains proper positioning during assembly and operation. This multi-functionality reduces the need for separate dedicated fixing components.
