Fitting Connector Dual Holding Structure Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fitting connectors face a challenge in maintaining a high holding force while preserving workability during connector insertion and extraction, as increased holding force often degrades the ease of fitting and releasing the connectors.
Innovation Solution
The fitting connector incorporates a dual holding structure with a slide locking mechanism and a detection member that allows for a flexible protrusion portion to regulate movement, ensuring a strong hold without compromising the ease of insertion and extraction by distributing the holding force across two structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the holding force is increased to keep the completely fitted state, then the holding force is improved, but the workability at the time of inserting and extracting the connectors degrades
Solution Approach 1:
The holding structure is divided into multiple locking portions (first locking portion, second locking portion, third locking portion) distributed at different positions and orientations. This segmentation allows the holding force to be distributed across multiple engagement points, increasing overall holding strength while maintaining reasonable insertion/extraction effort through progressive engagement
Solution Approach 2:
Different locking portions are designed with different geometric characteristics (hole portions, groove portions, protrusion portions) to create localized engagement features. Each locking portion provides holding force in specific directions, creating anisotropic holding characteristics that maintain strong retention while allowing controlled release during extraction
2Force
If the number of holding structure arrangement positions is increased, then the holding force is improved, but the device complexity increases
Solution Approach 1:
Multiple locking portions are integrated into a single holding structure assembly that engages with the counterpart housing simultaneously. The first, second, and third locking portions are combined in one structure rather than being separate components, increasing holding force without proportionally increasing overall device complexity
Solution Approach 2:
The holding structure serves multiple functions: it provides holding force through multiple locking portions, guides the insertion process, and enables detection of the completely fitted state. This multi-functionality reduces the need for additional separate components, maintaining complexity at acceptable levels while achieving enhanced holding force
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the holding force for maintaining a completely fitted state while preventing workability degradation, allowing for efficient insertion and extraction with reduced connector forces and improved vibration resistance.
Implementation Method 1
a flexible portion that has flexibility and is capable of moving the protrusion portion in a direction opposite to a direction in which the first locking holder is inserted into the locking portion while the flexible portion being bent
Implementation Method 2
a detection member that is a member for detecting the fitted state, is relatively movable to a main locking position with respect to the housing when the fitted state is in the completely fitted state

AI summary
A fitting connector includes: a first connector; a second connector; a detection member that is relatively movable to a main locking position with respect to a housing when the housings are completely fitted to each other and is locked to the housing at the main locking position; and first and second holding structures which keep the completely fitted state, in which the first holding structure includes a first locking holder for the housing with a locking portion and a second locking holder provided in the counterpart housing and entering the locking portion to regulate the relative movement between the housings in the completely fitted state, in which the second locking holder includes a protrusion portion entering the locking portion and a flexible portion capable of moving the protrusion portion in a direction opposite to the insertion direction toward the locking portion while being bent.
