Cable Noise Absorber With Deformable Bracket Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for absorbing electrical noise on cables are limited to a specific range of cable diameters due to the deformation range of their fixing means, restricting their applicability to larger diameter cables.
Innovation Solution
The device employs deformable U-shaped brackets with ribbing and a locking mechanism, allowing for a wider range of cable diameters to be accommodated by distributing clamping forces and enhancing holding strength without excessive clamping forces, and features a centering device for correct alignment and stabilization against axial pull.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid fixing means are used to secure the housing to the cable, then the holding strength is sufficient, but the device can only accommodate cables within a specific diameter range
Solution Approach 1:
The fixing means incorporate deformable elements that can dynamically adjust to different cable diameters. The housing includes elastic deformation zones that allow the fixing structure to adapt its shape and size to accommodate various cable dimensions while maintaining secure attachment.
Solution Approach 2:
The fixing means utilize material properties and structural design that allow parameter changes in response to cable diameter variations. The elastic deformation capability enables the fixing structure to change its dimensional parameters to match different cable sizes while preserving holding strength.
2Shape
If the housing is designed to be compact and smooth on the exterior, then the appearance is improved, but fixing means that protrude for clamping cannot be implemented
Solution Approach 1:
The fixing means are nested within the housing structure rather than protruding externally. The clamping mechanism is integrated into the housing body, allowing the exterior to remain smooth and compact while the internal structure performs the clamping function on cables.
Solution Approach 2:
The housing incorporates flexible regions with elastic deformation zones that enable the shell to adapt and clamp cables internally. This flexible design allows clamping functionality without external protrusions, maintaining a smooth housing exterior.

AI summary
A device for absorbing noise on cables comprises a housing consisting of two hinged halves. Each half is designed to hold a ferrite element. When the housing is closed, each end face has an opening to allow a cable to pass through. A fixing element, comprising two U-shaped brackets, is located on the inside of each end face. The opposing inner legs of the two brackets form a slot in which the cable is clamped. The inner legs are deformable perpendicular to the direction of the cable.
