Solution Overview
Problem
Existing sealing and locking devices for optical fiber cables are structurally complex, difficult to install and dismantle, and do not allow for precise positioning of stripped cable ends, making handling and routing of fibers within containers cumbersome and costly.
Innovation Solution
A container with a simplified sealing mechanism featuring a support frame with locking means, deformable elements, and compression elements that securely hold cables in place without requiring heat-shrinkable sheaths, ensuring axial locking and precise positioning of optical fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing and locking devices are used for optical fiber cables, then the cables can be sealed and locked, but the structural complexity increases and installation becomes difficult
Solution Approach 1:
The patent combines the sealing function and locking function into a single integrated device. The sealing element and locking mechanism are merged into one component that performs both functions simultaneously, eliminating the need for separate sealing devices and locking mechanisms, thus reducing structural complexity while maintaining both sealing and locking capabilities
Solution Approach 2:
The sealing and locking device is designed as a multi-functional component that can seal cable openings and lock cables in place simultaneously. This universal device replaces multiple specialized devices, simplifying the overall structure while providing comprehensive protection and securing for optical fiber cables
2Reliability
If traditional sealing and locking devices are used, then cables can be secured, but installation and dismantling become time-consuming
Solution Approach 1:
The sealing and locking device is designed with separable components that can be easily assembled and disassembled. The sealing element and locking mechanism are segmented in a way that allows quick installation by simply inserting the cable through the device, which then automatically engages the locking mechanism, significantly reducing installation and dismantling time while maintaining secure cable fixation
3Reliability
If traditional sealing devices are used, then cables can be sealed, but precise positioning of stripped cable ends is not achieved
Solution Approach 1:
The sealing device incorporates a positioning structure with a localized feature (such as a stepped surface or dedicated positioning ledge) that provides precise positioning for the stripped cable ends. This local quality enhancement ensures that cable ends are positioned accurately at a specific location within the sealed opening, facilitating proper routing and connection while maintaining the overall sealing function

AI summary
A device for sealing cables through containers for optical fibres comprises a support frame (1), a first compression element (19) mounted on the support frame (11), a second compression element (21) mounted on the support frame (11) and a deformable element (20) mounted on the support frame (11) between the first and second compression elements (19, 21). The device (1) is insertable in an inlet/outlet duct (4) of a container (2) for optical fibres and has at least one passage (22) for a cable (5), formed through the first and second compression elements (19, 21) and through the deformable element (20). Means for moving the first compression element (19) close to the second compression element (21) allows radial deformation of the deformable element (20) in such a manner as to obtain a sealing action of the deformable element (20) on an inner wall (4a) of the duct (4) and a sealing action of the deformable element (20) on the cable (5) located in the respective passage (22). Coupling means (18) placed at a distal end of the support frame (22) spaced apart from the first compression element (19) allows the device (1) to be secured to the container (2) in an integral manner.
