Quick Connector Reinsertion Inhibiting Boss Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick connectors fail to demonstrate the lock confirmation function when a piped body is reinserted without a specific operation to move the checker from the initial position to the lock confirmation position.
Innovation Solution
Incorporating a reinsertion-inhibiting boss that hooks onto the annular boss when the checker is at the lock confirmation position, preventing reinsertion and prompting the operator to move the checker to the initial position, thus ensuring the lock confirmation function is maintained during reinsertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the checker is moved to the lock confirmation position to confirm proper coupling, then the lock confirmation function is demonstrated, but the piped body cannot be reinserted without moving the checker back to the initial position
Solution Approach 1:
The reinsertion-inhibiting boss is positioned to preemptively block reinsertion of the piped body when the checker is at the lock confirmation position. This preliminary blocking action prevents unintended reinsertion while maintaining the lock confirmation function, resolving the contradiction between reliability and ease of operation.
2Ease of operation
If the piped body is reinserted without moving the checker to the initial position, then reinsertion is allowed, but the lock confirmation function is not demonstrated
Solution Approach 1:
The reinsertion-inhibiting boss provides visual and physical feedback to the operator about the checker's position. When the checker is at the lock confirmation position, the boss blocks reinsertion and signals to the operator that the lock confirmation function is active, ensuring proper operation sequence is followed.
3Ease of operation
If the checker remains at the initial position, then reinsertion is freely allowed, but the lock confirmation function is not demonstrated
Solution Approach 1:
The system requires the operator to perform the preliminary action of moving the checker to the lock confirmation position before reinsertion can be inhibited. This preliminary action ensures the lock confirmation function is properly demonstrated and recorded before preventing further reinsertion attempts.

AI summary
A quick connector, which can securely demonstrate the lock confirmation function by a checker when a piped body is reinserted, is provided. A checker includes reinsertion-inhibiting bosses. Thus, when a piped body is inserted through an opening of a retainer again in such a state as the checker is moved to the lock confirmation position after the piped body has been pulled from out of a housing and the retainer in such a state as the checker is moved to the release position, the reinsertion-inhibiting bosses hock up onto an annular boss, thereby inhibiting the piped body from being inserted into the retainer and housing.
