Retention Body for Fiber Optic Cable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable termination methods are challenging due to the difficulty in exposing strength elements from cables with high bonding between the strength elements and the cable jacket, making it time-consuming and difficult to achieve a robust, reliable, and easy-to-assemble connection.
Innovation Solution
A method for securing fiber optic cables to a retention body that involves partially exposing strength components while keeping them attached to the cable jacket, allowing for strain relief without fully stripping them, and using mechanical elements or bonding agents for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If strength elements are totally exposed from the cable jacket for termination, then the connector can be assembled, but the process becomes time-consuming and difficult for cables with high bonding between strength elements and cable jacket
Solution Approach 1:
The patent applies partial action by requiring only partial exposure of strength elements rather than complete exposure. The strength elements are exposed just enough to engage with the connector body, eliminating the need to completely strip them from the cable jacket. This reduces preparation time and difficulty while still achieving proper connector assembly.
2Loss of time
If strength elements are partially exposed while remaining attached to the cable jacket, then assembly is quicker and easier, but the pull-out strength may be compromised
Solution Approach 1:
The patent introduces a bonding agent as an intermediary substance that bonds the partially exposed strength elements to the connector body. This bonding agent compensates for the reduced mechanical engagement from partial exposure, ensuring that pull-out strength is maintained or enhanced despite the simplified preparation process.
3Strength
If strength elements are fully exposed, then mechanical engagement with connector is maximized, but the cable jacket integrity is compromised and strain relief is reduced
Solution Approach 1:
The patent applies partial action by exposing only the necessary portion of strength elements required for connector engagement. This partial exposure maintains sufficient cable jacket integrity and strain relief capability while providing adequate mechanical engagement with the connector body.
Solution Approach 2:
The bonding agent serves as an intermediary that provides the additional mechanical engagement needed when strength elements are only partially exposed. This allows the cable jacket to remain largely intact for proper strain relief while still achieving strong connector attachment through the combination of partial mechanical engagement and chemical bonding.

AI summary
Retention bodies for securing a fiber optic cable thereto for optical connectorization are disclosed along with fiber optic cable assemblies. The fiber optic cable is inserted into a passage of the retention body and secured to the same using a bonding agent and/or a mechanical element. The rear end opening of the passage is configured for inserting and securing an end portion of the fiber optic cable having at least one strength component and a portion of a cable jacket. Additionally, the retention body has a buckling chamber disposed within the retention body passage for accommodating movement of optical fiber.
