Guiding Support for Transmission Cable Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for terminating transmission cables, such as optical fiber cables, require cumbersome and time-consuming procedures involving crimping ferrules around Kevlar layers or central strength members to achieve strain relief, which are costly and inefficient.
Innovation Solution
A guiding support with a slot for receiving a fixation member of an end cap, allowing for low-stress accommodation of over-length transmission lines, eliminating the need for crimping and providing strain relief between the cable end and terminal, featuring a channel with a free space for longitudinal support and optional vertical or lateral displacement.

Engineering Contradiction Analysis
1Reliability
If crimping ferrule around Kevlar layer or central strength member is used to achieve strain relief, then strain relief is provided, but the procedure becomes cumbersome and time-consuming
Solution Approach 1:
The invention extracts the strain relief function from the crimping process by providing a dedicated holding structure with a slot that receives the fixation member. This separates the strain relief function (performed by the holding structure and fixation member engagement) from the termination process, eliminating the need for crimping ferrules and significantly reducing termination time while maintaining reliable strain relief.
Solution Approach 2:
The holding structure with the slot acts as an intermediary element between the fixation member and the guiding support. This intermediary structure provides a simple engagement mechanism where the fixation member is inserted into the slot, creating a positive mechanical connection that provides strain relief without requiring complex crimping operations.
2Volume of moving object
If high compression force is applied to the ferrule to store over-length transmission line, then the over-length is accommodated, but the compression force exceeds maximum specified by international standards
Solution Approach 1:
The invention removes the need for high compression force by providing a dedicated free space within the guiding support structure. The holding structure with its slot and the overall guiding support geometry create an accommodation zone for the over-length transmission line without requiring compressive forces, thereby staying within international standard specifications.
Solution Approach 2:
Instead of accommodating the over-length transmission line through compression in one dimension, the invention provides free space in multiple dimensions within the guiding support structure. The slot and channel geometry allow the transmission line to be stored in a volumetric manner rather than through linear compression, eliminating the need for excessive force.
3Reliability
If two separate actions are used for terminating the cable (fixing strength member and affixing transmission line), then strain relief is achieved, but the procedure becomes cumbersome
Solution Approach 1:
The invention merges the strain relief function and the transmission line guidance function into a single integrated guiding support structure. The holding structure with the slot provides strain relief through fixation member engagement, while the channel simultaneously guides the transmission line from the cable end to the terminal, eliminating the need for separate actions and reducing procedural complexity.
Solution Approach 2:
The guiding support structure serves multiple functions simultaneously: it provides strain relief through the holding structure and fixation member engagement, guides the transmission line through the channel, and accommodates the over-length transmission line within its free space. This multi-functional design eliminates the need for separate components and actions, simplifying the overall termination procedure.
