Optical Fiber Splice Device Rotary Connection for Confined Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable splice devices are limited in versatility and difficult to operate in narrow spaces due to their design, which causes interference and rigidity issues when trying to connect fiber optic cables to fitting devices.
Innovation Solution
A fiber optic cable splice device comprising a cable passage unit with a sleeve, inner tube, and limiting member, and a connection unit with a casing and rotary connection member, allowing the fiber optic cable to bend and connect to a fitting device without requiring the entire device to rotate, thus enabling operation in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tail part of the cable passage tube is curved to allow the fiber optic cable to bend nearly 90 degrees, then the fiber optic cable can be bent and connected, but the limiting member fixed to the cable passage tube rigidly holds the fiber optic cable and limits its movement
Solution Approach 1:
The patent changes the fixed connection between the limiting member and cable passage tube to a detachable connection. The limiting member can be removed and repositioned along the cable passage tube, allowing dynamic adjustment of the cable's bending radius and position. This enables the cable to bend naturally while maintaining connection flexibility.
2Ease of operation
If the threaded portion of the sleeve is connected to a fitting device by rotating the sleeve, then the fiber optic cable is connected to the fitting device, but the tail part and fiber optic cable rotate together occupying large space and interfering with the placement space
Solution Approach 1:
The patent extracts the rotation function from the entire cable assembly by making the limiting member detachable. Only the limiting member rotates with the sleeve during connection, while the cable passage tube and cable remain stationary. This separates the rotation action from the cable, dramatically reducing the space required for operation.
3Stability of the object's composition
If the limiting member is fixed to the cable passage tube, then the cable passage tube is limited within the receiving space, but the fiber optic cable is rigidly held and limited from moving slightly
Solution Approach 1:
The patent transforms the static fixed connection into a dynamic detachable connection. The limiting member can be removed, repositioned, and reattached at different locations on the cable passage tube, providing both position stability when attached and adjustment flexibility when detached or repositioned.

AI summary
A fiber optic cable splice device includes a sleeve, an inner tube received in the sleeve to allow passage of a fiber optic cable, and a limiting member coupled to the sleeve and limiting the limiting member in the sleeve. A casing is connected to the sleeve at a top end thereof, a joining portion extending sideward from a sidewall thereof, and a bent passage extending through the top end and the joining portion. A rotary connection member is rotatably positioned on the joining portion, and has a threaded plug. When the rotary connection member is rotated relative to the casing, the threaded plug is able to be threaded into a fitting device so that the fiber optic cable is connected to the fitting device.
