Compression Sleeve with Ramped Surfaces for Cable Grip Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art compression sleeves fail to maintain a stable grip on the outer conductor of cables during mechanical impacts, leading to unstable electrical conditions and incorrect signal transmission due to insufficient engagement by the first section around the corrugated outer conductor.
Innovation Solution
A compression sleeve design featuring a coned or ramped first section with a compression ring that securely presses against the outer conductor, combined with a coned or ramped transition to the second section, and an inner surface matching the corrugated outer conductor geometry, along with a projection to prevent axial sliding, ensures a firm grip and damping of vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projections are arranged on the inner side of the second section to press against the cable jacket, then the cable jacket is secured, but the first section does not obtain sufficient grip around the outer conductor
Solution Approach 1:
The compression sleeve is divided into two distinct sections: a first section with corrugated inner surface for gripping the outer conductor, and a second section with projections for pressing against the cable jacket. This segmentation allows each section to perform its specific function optimally without interfering with the other.
Solution Approach 2:
Different regions of the compression sleeve are given different surface properties: the first section has a corrugated inner surface matching the outer conductor's geometry for enhanced grip, while the second section has projections for cable jacket compression. This local differentiation of properties ensures each area performs its intended function effectively.
2Reliability
If the compression sleeve exerts pressure against the cable, then the cable is secured in the connector, but the grip around the outer conductor is insufficient under mechanical impacts
Solution Approach 1:
The inner surface geometry of the first section is changed to match the corrugated geometry of the outer conductor. This geometric parameter change enhances the contact area and friction between the compression sleeve and outer conductor, providing superior grip strength that resists mechanical impacts and maintains electrical stability.
3Strength
If a compression ring with coned surface is added to press the first section against the outer conductor, then grip strength is improved, but device complexity increases
Solution Approach 1:
The compression ring is integrated with the compression sleeve to form a unified assembly. The coned surface of the compression ring works in conjunction with the coned outer surface of the first section, creating a combined clamping mechanism that achieves high grip strength on the outer conductor while maintaining structural coherence.
Solution Approach 2:
Coned and ramped surfaces are employed on both the compression ring and the first section of the compression sleeve. These curved geometric forms distribute the compressive force evenly around the outer conductor, maximizing contact area and clamping effectiveness while preventing stress concentration points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable and immovable grip on the outer conductor, maintaining consistent electrical conditions even under mechanical stress, ensuring reliable signal transmission.
Implementation Method 1
the compression ring, when the front nut is threaded together with the connector body, presses the first section or first end of the compression sleeve against the outer conductor of the cable
Implementation Method 2
When the compression ring is formed with a coned or ramped surface that adjoins the coned or ramped surface of the first section or first end, a great clamping force is achieved from the compression sleeve against both the cable jacket and the outer conductor
Implementation Method 3
the coned or ramped surface at the first section or first end of the compression sleeve terminate by a projection defining a hole which has the same diameter as the hole in the free end of the exposed outer conductor
Implementation Method 4
the inner surface of the second section or second end of the compression sleeve is formed with a projection, which ensures damping of vibrations from the cable, when it is manipulated in the vicinity of the connector

AI summary
To ensure stable physical and electrical contact between an exposed outer conductor of a cable and a compression sleeve, which has two sections, where the first section is disposed around the jacket of the cable, while the second section is disposed around the outer conductor of the cable, which is corrugated, and where the shield and the jacket of the cable are mounted in a connector formed by a front nut and a connector body, screwing together of the front nut and connector body will cause the compression sleeve to be clamped tightly to the outer conductor, as a compression ring is disposed around the second section, said compression ring has coned or ramped surfaces on the sleeve, said coned or ramped surfaces being disposed at the free end of the first section and at the transition between the first section and the second section.
