Connector Resilient Positioning Members Vibration Attenuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with ring-shaped resilient portions require excessive material, increasing costs due to the continuous circumference design, which is not efficiently addressing vibration attenuation and material usage.
Innovation Solution
A connector design featuring two spaced-apart resilient positioning members with inward and outward facing ribs that allow for flexible deformation without restriction, positioned between the inner and outer housings to absorb vibrations and maintain relative displacement, reducing material usage and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ring-shaped resilient portion continuous over the entire circumference is used, then vibration attenuation is achieved, but material cost increases
Solution Approach 1:
The continuous ring-shaped resilient portion is divided into multiple discrete resilient positioning members (first and second resilient positioning members) spaced apart circumferentially. This segmentation reduces material consumption while maintaining the vibration attenuation function through the distributed resilient elements that independently deform to absorb vibrations.
Solution Approach 2:
Instead of providing resilient support continuously around the entire circumference, the invention uses a partial arrangement of resilient positioning members at specific locations. This partial action is sufficient to achieve the required vibration attenuation and housing positioning without the excessive material usage of a complete ring.
2Reliability
If resilient positioning members with inward and outward facing ribs are used, then vibration suppression is improved, but device complexity increases
Solution Approach 1:
The resilient positioning members integrate multiple functions into a single component: the base plate provides positioning contact, while the inward and outward facing ribs provide vibration attenuation through resilient deformation. This merging of functions into unified resilient positioning members reduces the total number of separate components needed.
Solution Approach 2:
The resilient positioning members utilize flexible rib structures that can deform elastically to absorb vibrations. The thin, flexible nature of the ribs allows them to function as vibration-damping elements while maintaining structural integrity and providing the necessary positioning force.

Function Achieved in This Case
The connector effectively suppresses vibration and maintains relative displacement between housing components, reducing material costs while ensuring reliable vibration attenuation and preventing sliding abrasion between terminal fittings.

AI summary
A connector (F) includes an inner housing (11). Terminal fittings (72) fixed to front end parts of wires (71) are inserted into the inner housing (11) from behind. An outer housing (37) is mounted relatively displaceably with respect to the inner housing (11) and is held out of contact with the terminal fittings (72). Two resilient positioning members (55) are configured to position the inner housing (11) and the outer housing (37) and spaced apart in a circumferential direction.
