Optical Fiber Fusion Splicer High Voltage Covering Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber fusion splicers require cumbersome two-step processes for removing and replacing electrode rods, with tight screw tightening needing precise alignment and small space handling, which complicates operability and safety.
Innovation Solution
A covering device with a removably connectable cover body and electrode retainer that collectively holds and positions the electrode rod, featuring a tool insertion hole for secure screw access and holding pawls for easy rod engagement and disengagement, allowing for one-step removal and replacement without pressing the electrode rod collar during screw tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fitting screw is tightened while pressing the electrode rod collar, then the electrode rod can be fixed securely, but the operability becomes difficult due to tight space and precise alignment requirements
Solution Approach 1:
The electrode retainer is divided into separate functional components: the collar portion that presses the electrode rod, the body portion that houses the screw mechanism, and the positioning features. This segmentation allows the screw to be tightened independently without requiring precise alignment of the entire assembly, improving operability while maintaining secure fixation.
Solution Approach 2:
The electrode retainer collar acts as an intermediary element between the screw mechanism and the electrode rod. It transmits the pressing force from the screw to the electrode rod collar, enabling secure fixation without requiring direct manipulation of the electrode rod during screw tightening, thus improving ease of operation.
2Ease of operation
If the electrode cover and electrode retainer are removed separately, then the electrode rod can be accessed, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The electrode cover and electrode retainer are merged into a single integrated assembly that can be removed and installed as one unit. This combining of components eliminates the need for separate removal and installation steps, significantly reducing the time and complexity of the electrode rod replacement process while maintaining easy access to the electrode rod.
3Ease of manufacture
If the fitting screw head is exposed for tool access, then the screw can be tightened, but the high voltage safety is compromised due to exposed metallic parts
Solution Approach 1:
The screw mechanism is nested within the electrode retainer body, with the screw head accessible through a dedicated opening in the cover body. This nesting arrangement allows tool access to the screw while keeping the high-voltage electrode components enclosed and isolated, maintaining safety while enabling manufacturing and assembly operations.
Solution Approach 2:
The cover body is segmented with a specific opening or access hole positioned to allow tool access to the screw mechanism without exposing the high-voltage electrode components. This segmentation of the cover body creates distinct functional zones: one for tool access and another for high-voltage isolation, resolving the contradiction between ease of manufacture and safety.
