Pivoting Oscillation Suppressor for Connector Housing Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automotive engineering, electrically conductive contact elements in plug connections experience increased wear and abrasion due to frictional relative motion under vibrations, affecting operating behavior.
Innovation Solution
A connector housing with a pivotable oscillation suppressor that reduces the cable duct dimension to match the electrical cable's outer diameter, clamping the cable between projections and a partition wall to restrict motion and increase clamping force, thereby reducing susceptibility to vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If play is provided for positioning and mounting contact elements to compensate for manufacturing tolerances, then ease of assembly is improved, but vibration resistance deteriorates due to frictional relative motion between contact surfaces
Solution Approach 1:
The oscillation suppressor is designed to pivot between a retracted position (during assembly) and a protruding position (during operation). This dynamic mechanism allows the system to adapt: during assembly, the suppressor is retracted to provide play for contact element positioning; during operation, it protrudes to clamp the cable and eliminate relative motion, thus resolving the contradiction between ease of assembly and vibration resistance
Solution Approach 2:
The oscillation suppressor is implemented as a separate, movable component that can be pivoted into position, rather than being a fixed integral part of the connector housing. This segmentation allows the suppressor to be positioned dynamically - retracted during assembly to facilitate contact element installation, and protruding during operation to provide vibration protection by clamping the cable
2Reliability
If an oscillation suppressor is pivoted into the cable duct to clamp the cable, then vibration resistance is improved, but the cable duct clear dimension must be reduced to match the cable outer diameter
Solution Approach 1:
The oscillation suppressor uses a pivotal motion to dynamically change the cable duct's clear dimension. When retracted, the cable duct has a larger clear dimension allowing easy cable insertion. When pivoted into the protruding position, the suppressor reduces the clear dimension to match the cable outer diameter, creating a clamping effect that provides vibration resistance without requiring a permanently constrained cable duct design

AI summary
A connector housing for an electrical plug connector includes a cable duct and an oscillation suppressor pivotable about a pivot axis into the cable duct. The cable duct receives an electrical cable of a predefined outer diameter along a plug-in direction. The cable duct in a cross section perpendicular to the plug-in direction has a clear dimension in a pivoted state of the oscillation suppressor in the cable duct equal to or less than the predefined outer diameter of the electrical cable.
