Electrical Connection Terminal With Movable Isolating Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection terminals require significant installation space and complex structures when multiple guide shafts are needed for switching, disconnecting, and testing tasks, especially in current transformer measuring circuits.
Innovation Solution
An electrical connection terminal with a movable separating device featuring a contact tap that can be actuated by a test plug, allowing for direct placement on the isolating device, reducing installation space and enabling flexible operation without additional tools, and incorporating a pivoting or translational movement mechanism for easy and robust separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple guide shafts are provided for test plugs and switching bridges, then switching and testing functionality is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the separating device and test plug functionality into a single integrated unit. The test plug is inserted into the isolating device housing and directly contacts the contact taps on the separable connection elements, eliminating the need for separate guide shafts while maintaining both switching and testing capabilities.
Solution Approach 2:
The isolating device housing serves multiple functions: it provides mechanical protection, guides the test plug insertion, and directly provides electrical contact through contact taps on the separable connection elements. This multi-functional design replaces what would traditionally require separate dedicated components.
2Adaptability or versatility
If multiple guide shafts are provided for test plugs and switching bridges, then switching and testing functionality is improved, but installation space requirements increase

3Ease of operation
If a pivoting separating knife is provided centrally, then separating functionality is improved, but device complexity and installation space increase
Solution Approach 1:
The patent extracts the contact function from a centralized pivoting knife and distributes it to contact taps directly on the separable connection elements. This eliminates the need for a complex central pivoting mechanism while maintaining the separating functionality through direct contact separation.
