Fiber Closure External Cable Clip for Radial Movement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber cable systems lack external support, leading to potential damage during installation and movement, as they are not properly secured within fiber closures, and prior art solutions focus on sealing inside the closure port rather than providing external support.
Innovation Solution
A fiber closure external cable clip with a petal region and anchoring region, featuring integrally molded petal clamps and anchoring clamps, securely attaches to the fiber closure port, restricting movement of optical fiber cables and providing external support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical fiber cables are locked inside the fiber closure using strength members, then the cables are secured within the closure, but the cables lack external support and can be damaged during installation and movement
Solution Approach 1:
The cable securing system is divided into two independent parts: internal strength members that lock cables within the closure, and external cable clips that provide external support. This segmentation allows each component to perform its specific function optimally without interfering with the other.
Solution Approach 2:
External cable clips act as intermediary components between the optical fiber cables and the external environment. These clips provide additional support and protection during installation and movement, bridging the gap between internal cable locking and external cable handling.
2Object-affected harmful factors
If seal blocks and resin filling are used to seal the closure port, then the port is sealed against moisture and contaminants, but external support for entering/exiting cables is not provided
Solution Approach 1:
The external cable clip is designed as a multi-functional component that simultaneously provides external cable support and maintains port sealing. By integrating the sealing function into the cable clip structure, a single component performs both support and protection functions.
Solution Approach 2:
The invention merges the cable support function and the sealing function into a single integrated external cable clip assembly. This combination eliminates the need for separate sealing components and provides both functions through one unified structure.
3Ease of operation
If optical fiber cables are not properly locked, then installation and access are simplified, but pulling the cable from outside can result in damage to connectivity
Solution Approach 1:
External cable clips are installed on the closure port before cable installation. This preliminary action creates pre-positioned external support structures that guide and protect cables during the installation process, preventing damage before it can occur.
Solution Approach 2:
The external cable clips provide beforehand cushioning by creating a protective interface between the cable and external forces. This cushioning effect absorbs and distributes pulling forces, preventing direct transmission of stress to the cable connectivity points.

AI summary
Disclosed is a fiber closure external cable clip (100, 200, 300) to be mounted on a port (102) of the fiber closure (104) comprises a petal region (106) configured to be detachably secured with the port (102) and an anchoring region (108) having one or more anchoring clamps (116) is structurally connected to the petal region (106). In particular, the optical fiber cable entering and/or exiting the fiber enclosure (104) is detachably secured to exactly one anchoring clamp of the one or more anchoring clamps (116), thereby restricting a radial movement of the optical fiber cable (130).
