Cable Anchor Sheath Locking for High-Tension Support Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable anchoring devices fail to securely hold cables in place during high-tension events, leading to potential damage to support structures and network integrity due to cable deformation or detachment.
Innovation Solution
A cable anchoring device with a U-shaped sheath and a plate featuring tabs with notches that engage with the sheath to prevent detachment, combined with separation means that activate above a predefined tension threshold to protect the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If tabs of the plate simply abut against the sheath, then the structure is simple, but the cable can deform the tabs under high tension and detach from the sheath
Solution Approach 1:
The tab is segmented by introducing a notch that divides the tab structure into distinct regions. This segmentation allows the tab to engage with the sheath in a controlled manner, creating multiple engagement points that distribute the load and prevent tab deformation under high tension while maintaining structural simplicity.
2Reliability
If the cable is securely held in the anchoring device, then the cable remains stable during normal operation, but excessive tension can still damage the support structure
Solution Approach 1:
The anchoring device incorporates dynamic characteristics through the movable plate that can shift position along the cable. Under normal operation, the plate remains stationary providing stable cable holding. When excessive tension occurs, the plate moves dynamically to activate the cutting mechanism, allowing the system to adapt its behavior based on loading conditions and protect the support structure.
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 device ensures secure cable retention and protects support structures by engaging tabs with the sheath and activating separation mechanisms to prevent excessive tension damage.
Implementation Method 1
the movement of the sheath upstream relative to the body causing the clamping wedge to move closer to the base of the sheath
Implementation Method 2
the tab of the plate comprises a notch which, in the mounted position, is capable of engaging with the sheath following traction exerted on the cable upstream
Implementation Method 3
separation means configured to cause, in the mounted position, the separation from the support of an upstream portion of a cable placed in the housing of the device, said separation means being configured to be activated when a traction exerted on the cable in the upstream direction exceeds a predefined threshold
