Cable Fixing Device with Locking Slider and Clamping Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable fixing devices fail to securely hold cables in a non-rotatable and tensile force-resistant manner to cable outlet connectors, often requiring excessive pressure or specialized tools.
Innovation Solution
A cable fixing system comprising a clamping sleeve, locking collar, and locking slider, which integrates a cable strain relief and sealing system, ensures secure attachment by guiding the clamping sleeve between the locking collar's side surfaces and using a U-shaped locking slider with latching openings to engage with the cable outlet connector's latching noses, preventing removal and providing rotational restraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If flexible clamping tongues are pressed together to clamp the cable, then the cable can be secured to the cable outlet connector, but the pressing pressure may not attain the required level for secure non-rotational and tensile force-resistant fixation
Solution Approach 1:
The clamping function is divided into two independent components: the clamping sleeve with clamping elements for radial clamping, and the locking slider with latching noses for axial and rotational locking. This segmentation allows each component to perform its specific function optimally without compromising the other.
Solution Approach 2:
The invention merges multiple fixation functions (radial clamping, axial positioning, and rotational locking) into a single integrated cable fixing device that combines the clamping sleeve, locking collar, and locking slider components working together.
2Reliability
If a cable screw means is used to secure the cable, then the cable can be fixed to the cable outlet connector, but a special tool is required for installation
Solution Approach 1:
The locking slider is designed to be manually operable without special tools. The locking mechanism engages and disengages through simple manual manipulation of the locking slider, allowing installers to perform the fixation task themselves without requiring specialized tooling.
Solution Approach 2:
Instead of using a screw mechanism that requires rotational torque applied through a tool, the invention inverts the approach by using a sliding mechanism where the locking action is achieved through linear movement of the locking slider along the cable axis, which can be done manually.
3Reliability
If the clamping sleeve is designed to prevent removal by its peripherally extending edge, then the cable fixation becomes secure and non-rotatable, but the device complexity increases with multiple components
Solution Approach 1:
The clamping sleeve is nested within the locking collar, and the locking slider moves within the locking collar. This nested arrangement allows multiple functional components to be compactly integrated without significantly increasing the overall device footprint or complexity.
Solution Approach 2:
The locking collar serves multiple functions: it provides the structural housing for the locking mechanism, guides the locking slider movement, and engages with the cable outlet connector. This multi-functionality reduces the need for separate components for each function.
