Rotating Ground Switch Plate for Selective Line Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing termination points for electrically conductive lines do not provide an efficient method to isolate specific conductive lines for testing or tracing without disconnecting and reconnecting all bonded connections, which is time-consuming and inefficient.
Innovation Solution
An isolation ground switch with a rotatable conductive switch plate and termination studs, allowing easy isolation of conductive lines by switching between closed and open positions, ensuring conductive contact in the closed state and isolation in the open state, facilitated by a rotation hub and latching mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If termination points bond multiple conductive lines at a common location, then grounding and bonding efficiency is improved, but the ability to easily isolate specific lines for testing deteriorates
Solution Approach 1:
The switch plate is divided into multiple independently operable sections, each corresponding to a specific conductive line. This segmentation allows individual lines to be isolated by moving only the relevant switch plate section, while other lines remain connected. The segmentation resolves the contradiction by enabling selective isolation without affecting the overall bonded connection structure.
Solution Approach 2:
The switch plate sections are made movable between connected and isolated positions, transforming a static bonding structure into a dynamic one. This dynamic capability allows the system to adapt between states of full connectivity and selective isolation, resolving the contradiction between maintaining efficient bonded connections and enabling easy line isolation for testing.
2Reliability
If each conductive line is disconnected and reattached for testing, then complete isolation is achieved, but time consumption and operational inefficiency increase
Solution Approach 1:
The switch plate sections are pre-configured in the connected position during installation, establishing default connectivity. For testing, only a simple rotational movement is needed to isolate a specific line, rather than performing complete disconnection and reattachment procedures. This preliminary configuration resolves the contradiction by enabling rapid isolation when needed while maintaining reliable connectivity during normal operation.

AI summary
An isolation ground switch has a housing having a front housing portion and a back housing portion defining a housing cavity therebetween. A conductive switch plate is positioned in the housing cavity and rotatable between a closed position and an open position. A plurality of termination studs are mounted to the front housing portion, each termination stud having a conductive projection extending into the housing cavity. The conductive projection of each termination stud engages the switch plate when the switch plate rotates to the closed position, and when the switch plate rotates to the open position, the switch plate does not contact the termination studs and is conductively isolated.
