Optical Connector Movable Anchoring Fixture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-site installable optical connectors face difficulties in handling and connecting optical fibers due to the challenge of covering the outer boot of optical drop and indoor cables, leading to complex and cumbersome operations.
Innovation Solution
An optical connector design featuring a ferrule with a first optical fiber housed to project from its back end and an anchoring fixture with a groove that anchors a second optical fiber, allowing for easy connection and flexible alignment, including a movable connecting portion that accommodates bending and prevents local stress concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional on-site installable optical connector is used on optical drop cables or indoor cables, then the connector can be installed at connection sites, but the operation becomes difficult and cumbersome due to the challenge of covering the outer boot
Solution Approach 1:
The optical connector is divided into two separate parts: a connector body and an anchoring fixture. The anchoring fixture with the anchoring groove is attached to the optical fiber cable first, and then the connector body is connected to it. This segmentation allows the outer boot to be properly covered and secured without difficult operations.
Solution Approach 2:
The anchoring fixture serves as an intermediary component between the optical fiber cable and the connector body. It provides a bridging structure that includes an anchoring groove for securing the outer boot and a connecting portion for attaching to the connector body, simplifying the overall installation process.
2Ease of manufacture
If the outer boot is simply removed to expose the coated optical fiber, then the connector can be attached, but covering the outer boot with a rubber boot becomes difficult and operationally cumbersome
Solution Approach 1:
The anchoring groove is pre-formed in the anchoring fixture before assembly. This preliminary structure allows the outer boot to be easily inserted and secured without requiring complex covering operations with rubber boots, as the anchoring groove itself provides the necessary retention structure.
3Stability of the object's composition
If the anchoring fixture is rigidly connected to the connector body, then the connection is stable, but bending stress concentrates locally in the optical fiber
Solution Approach 1:
The connecting portion between the anchoring fixture and connector body is designed with movable characteristics that allow relative movement. This dynamic connection allows the anchoring fixture to move relative to the connector body when the optical fiber cable bends, preventing stress concentration while maintaining connection stability.
4Reliability
If the optical fiber is tightly fixed in the anchoring groove, then the connection is secure, but the handling characteristics deteriorate due to reduced flexibility
Solution Approach 1:
The connecting portion allows relative movement between the anchoring fixture and connector body, providing flexibility for handling and installation while the anchoring groove maintains secure fixation of the optical fiber cable. This dynamic design balances connection security with operational flexibility.

AI summary
An optical connector includes a connector body that has a first optical fiber housed in advance in a ferrule so as to project from a back end of the ferrule opposite to the connecting end surface and an anchoring fixture that anchors a second optical fiber that is to be optically connected to the first optical fiber, and by pressing the anchoring fixture into the connector body while the second optical fiber is anchored in this anchoring fixture, the anchoring fixture and the connector body are connected to optically connect the first optical fiber and the second optical fiber, and the connecting portion that connects the anchoring fixture and the connector body form a movable connecting portion that is adapted to vary the direction of the anchoring fixture with respect to the connector body.
