Connector Regulating Section for Terminal Stability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Connectors with terminals featuring a tab-shaped electrical connection section and raised parts face looseness issues when fitted with female screws, requiring a configuration to prevent terminal collision and simplify the terminal accommodating chamber structure to reduce manufacturing costs.

Innovation Solution

A connector design with a terminal insertion hole featuring a regulating section that protrudes from the peripheral edge, positioned opposite to the raised part, to prevent looseness and stabilize the terminal's posture, while maintaining a simplified structure by integrating the regulating section within the housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a configuration is added to suppress terminal looseness, then terminal stability is improved, but device complexity increases

Engineering Contradiction:

Improveterminal stabilityVSAvoidterminal accommodating chamber structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The regulating section is integrated into the peripheral edge of the terminal insertion hole, merging the looseness regulation function with the existing housing structure. This eliminates the need for separate components while maintaining terminal stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The regulating section is positioned at a specific location (peripheral edge of insertion hole) rather than requiring a complete structural redesign of the entire terminal accommodating chamber. This localized approach reduces overall complexity while solving the looseness issue.

Inventive Principle:

Principle #1Segmentation

2Reliability

If additional components are added to regulate terminal looseness, then terminal stability is improved, but manufacturing costs increase

Engineering Contradiction:

Improveterminal stabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The regulating section is formed as an integral part of the connector housing's terminal insertion hole structure. This consolidation reduces the total number of components that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining terminal stability.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If the terminal insertion hole structure is simplified, then manufacturing cost is reduced, but terminal looseness control is worsened

Engineering Contradiction:
