Rotating Node Harness Feed-Through Connector for Fiber Optic Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ninety-degree connectors for optical fiber cables face difficulties in feeding fibers due to the challenge of bending them ninety degrees to pass through the connector, making the connection process cumbersome.
Innovation Solution
A connector that rotates between a straight and angled position, featuring a cabinet-side and cable-side swivel portion with passageways positioned at different angles, and a securing mechanism to securely attach the cable-side portion to the cabinet-side portion, facilitating easier fiber feeding by allowing the connector to swivel between positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional ninety-degree connector is used, then the connector can redirect the cable at ninety degrees, but it becomes difficult to feed optical fibers through the connector due to the challenge of bending them ninety degrees
Solution Approach 1:
The connector incorporates a swivel mechanism that allows the cable-side body portion to rotate relative to the cabinet-side body portion between a cable installation position and an angled position. This dynamic adjustment enables the connector to adapt its configuration during installation, making fiber feeding easier by allowing the fibers to be inserted when the connector is in the straight cable installation position, then rotated to the angled position for final connection.
Solution Approach 2:
The connector is divided into separate body portions: a cabinet-side body portion and a cable-side body portion, each with its own swivel portion. This segmentation allows each portion to be optimized independently and enables relative rotation between the portions, facilitating easier fiber insertion and connection while maintaining the final angled configuration.
2Ease of operation
If the connector is designed to rotate between straight and angled positions, then fiber feeding is simplified, but the device complexity increases due to additional swivel portions and securing mechanisms
Solution Approach 1:
The swivel mechanism enables the connector to transition between a cable installation position (straight configuration) and an angled position. During installation, the connector can be positioned in the straight configuration for easier fiber feeding, then rotated to the angled position for final connection to the cabinet. This dynamic capability simplifies the installation process despite the added complexity of the swivel portions and securing mechanisms.
3Adaptability or versatility
If the passageways are positioned at different angles in the cable installation position and angled position, then the connector can accommodate fiber bending, but the manufacturing precision requirements increase
Solution Approach 1:
The connector's passageways are designed with specific angle relationships that change between the cable installation position and the angled position. In the cable installation position, the passageways are positioned to facilitate easy fiber insertion with minimal bending. When rotated to the angled position, the passageways accommodate the ninety-degree redirect. This dynamic geometric configuration provides adaptability while maintaining manufacturability through standardized angular relationships.
Solution Approach 2:
The connector is segmented into cabinet-side and cable-side body portions, each with independently designed passageways. The cabinet-side body portion includes a passageway that extends through the body, and the cable-side body portion includes a passageway that extends through its body. These segmented passageways can be manufactured with standard precision tolerances while achieving the desired angular relationships when the portions are assembled in their relative positions.
