Conductive Panel Connection Device for Switchboard Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for grounding conductive panels in electrical switchboards require a separate step for electrical connection, which complicates the mounting and maintenance process by necessitating initial grounding followed by mechanical fixation.
Innovation Solution
A connection device made of conductive metallic material, shaped as a frame with a protruding tab and scratching members, allows simultaneous electrical and mechanical fixation of panels to the switchboard framework, enabling a stable ground connection during panel installation or removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate lead with terminals and screws is used for ground connection, then a stable electrical connection is achieved, but the mounting process becomes complex and time-consuming requiring separate grounding and mechanical fixation steps
Solution Approach 1:
The patent combines the electrical connection function and mechanical fixation function into a single integrated connection device. The connection device includes a body with a first end that electrically connects to the panel and a second end that mechanically fixes to the switchboard framework, eliminating the need for separate grounding leads and mechanical fasteners.
Solution Approach 2:
The connection device serves multiple functions simultaneously: it provides electrical grounding connection through its conductive body, provides mechanical support and fixation through its structure that engages with the switchboard framework, and ensures stable electrical contact through its design that maintains pressure between contact surfaces.
2Reliability
If a lead with terminals and screws is used for ground connection, then a stable electrical connection is achieved, but the mounting time increases due to sequential grounding and mechanical fixation steps
Solution Approach 1:
The patent combines the electrical connection function and mechanical fixation function into a single integrated connection device. The connection device includes a body with a first end that electrically connects to the panel and a second end that mechanically fixes to the switchboard framework, eliminating the need for separate grounding leads and mechanical fasteners.
Solution Approach 2:
The connection device is pre-configured with both electrical connection elements and mechanical fixation elements in their proper positions and orientations. This preliminary arrangement allows the installer to perform both grounding and mechanical fixation in a single operation rather than sequentially, reducing mounting time.
3Reliability
If separate grounding and mechanical fixation steps are required, then stable electrical connection is ensured, but the ease of operation during mounting and maintenance is reduced
Solution Approach 1:
The patent combines the electrical connection function and mechanical fixation function into a single integrated connection device. The connection device includes a body with a first end that electrically connects to the panel and a second end that mechanically fixes to the switchboard framework, eliminating the need for separate grounding leads and mechanical fasteners.
Solution Approach 2:
The connection device is designed to automatically perform both electrical connection and mechanical fixation functions when installed. The single component structure with integrated electrical contacts and mechanical engagement features allows the device to serve multiple purposes simultaneously without requiring separate operations for grounding and mounting.
