Quick Connector Locking Ring Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick connectors experience vibrations due to the offset sealing and retention mechanism, leading to potential wobbling issues between the male and female connector members.
Innovation Solution
The introduction of a locking ring with first and second fitting parts that enhance the support strength between the male and female connector members, along with operational pieces for improved assembly and disassembly, reduces vibrations and wobbling by providing additional stability and ease of use without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing portion and retention portion are offset from each other, then the connector can be easily assembled and disassembled, but vibrations and wobbling occur between the male and female connector members
Solution Approach 1:
A locking ring is introduced as an intermediary component between the male and female connector members. The locking ring includes a first fitting part that fits between the inner periphery of the retaining member and the outer periphery of the male connector member, providing additional support and reducing vibrations while maintaining the offset configuration for easy assembly and disassembly
2Ease of manufacture
If the locking ring is provided with operational pieces for diameter reduction, then the assembling properties are enhanced, but the device complexity increases
Solution Approach 1:
The locking ring incorporates operational pieces that can be dynamically deformed to reduce the diameter of the locking ring body. This dynamic capability allows the locking ring to be easily assembled by compressing it through the female connector member, and then expanding to lock in place, enhancing assembling properties while the operational pieces serve as integrated manipulation features rather than separate components

AI summary
A quick connector is capable of reducing wobbling due to vibrations, and even after the retaining member is reused repeatedly, sealing property can be maintained and wobbling can be made smaller. A quick connector is provided with, a female connector member, a male connector member which fits into the female connector via a sealing member, and a retaining member which exists in a circular space between these connector members, interposed between the inner periphery of the female connector member and the outer periphery of the male connector member to be engaged therewith, thereby preventing the male connector member from coming off in the connector central line direction, wherein, a locking ring having a first fitting part which fits between the inner periphery of the retaining member and the outer periphery of the male connector member is provided on the outer periphery of the male connector member.
