Fiber Optic Cable Enclosure Anti-Rotation Port Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable securing systems require multiple clamping mechanisms to prevent axial displacement between cable jacketing and strength members, which can be cumbersome and inefficient, especially in dense array configurations where space is limited.
Innovation Solution
An enclosure system with a cable receiving port that allows axial insertion of a plug without rotation, featuring an anti-rotation member and engagement mechanism to limit cable movement, enabling secure environmental sealing and retention without additional space-consuming components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple clamping mechanisms are used to secure cable jacketing and strength members, then axial displacement is prevented, but device complexity and space requirements increase
Solution Approach 1:
The patent combines the functions of securing the cable jacketing and strength members into a single integrated clamping mechanism. The clamp simultaneously engages both the jacketing material and the strength members, eliminating the need for separate clamping devices for each component. This merging reduces device complexity while maintaining the reliability of preventing axial displacement between cable components.
Solution Approach 2:
The clamping mechanism is designed to perform multiple functions: it secures the cable jacketing, holds the strength members, and prevents axial displacement all in one device. This multi-functional clamp reduces the overall number of components needed in the cable securing system, addressing the contradiction between reliability and device complexity.
2Reliability
If multiple clamping mechanisms are used to secure cable components, then axial displacement is prevented, but installation space and enclosure size increase
Solution Approach 1:
By merging the clamping functions for jacketing and strength members into a single clamp, the patent significantly reduces the space required in the enclosure. Instead of allocating space for multiple separate clamping mechanisms, the integrated design consolidates all securing functions into one compact device, thereby reducing the overall footprint of the cable securing system.
3Ease of operation
If cable insertion allows rotation during advancement, then insertion is easier, but cable alignment and positioning precision deteriorate
Solution Approach 1:
The patent employs asymmetric features in the cable insertion interface, such as a flat surface or keyway on the cable connector that corresponds to a matching feature in the enclosure port. This asymmetric design prevents rotation during insertion by providing a unique orientation, ensuring precise cable alignment while still allowing straightforward push-in installation. The asymmetric geometry guides the cable into the correct position without requiring rotational adjustment.

AI summary
An enclosure system for receiving a cable includes an enclosure having an inner chamber and an open position exposing the inner chamber and a closed position covering the inner chamber. A cable receiving port in a wall of the enclosure extends along a longitudinal axis from outside of the enclosure into the inner chamber. The cable receiving port is configured to receive a cable therein when the cable is advanced axially into the port without rotation of the cable when the enclosure is in the closed position. A mating member is associated with the cable receiving port that limits rotation of the cable when the cable is advanced axially into the port. An axial retention member is associated with the cable receiving port that limits axial movement of the cable out of the port when the cable is advanced axially into the port to a lock position.
