Connector Housing Slit Positioning to Reduce Stacking Tolerances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face complexity in maintaining connection accuracy due to fitting tolerances between the connector and housing, as well as between connection and mounting terminals, which complicates design and accuracy.
Innovation Solution
A connector design featuring a housing with a slit for positioning a flat plate-like guide portion of the mounting terminal, eliminating the need for a receptacle and simplifying the configuration by integrating a locking function into the guide portion, allowing for improved accuracy and miniaturization by reducing stacking tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a receptacle is used to hold the mounting terminal, then the connector can be assembled, but stacking tolerances accumulate and connection accuracy deteriorates
Solution Approach 1:
The patent extracts and eliminates the receptacle component from the connector assembly. By removing the receptacle, the mounting terminal is positioned directly in the housing, which eliminates the intermediate fitting interface and its associated stacking tolerances, thereby improving connection accuracy while simplifying the overall structure.
Solution Approach 2:
The patent merges the positioning function previously performed by the receptacle directly into the housing structure. The housing now directly holds and positions the mounting terminal through integrated positioning features, eliminating the need for a separate receptacle component and reducing the number of fitting interfaces.
2Volume of moving object
If multiple components (receptacle, housing, mounting terminal) are used, then the connector can be assembled, but the number of parts increases and miniaturization becomes difficult
Solution Approach 1:
The patent extracts and removes the receptacle component from the assembly, reducing the total number of parts. This elimination of unnecessary components directly contributes to miniaturization by reducing the overall volume and simplifying the connector structure.
Solution Approach 2:
The patent combines the functions of the receptacle and housing into a single integrated housing structure. This merging of components reduces the number of separate parts, simplifies assembly, and enables miniaturization by eliminating the space and complexity associated with multiple discrete components.
