Terminal Block Busbar Assembly Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of managing various types of terminal blocks for different devices, such as inverters, due to varying shapes and positions of mounting holes and terminals, leads to cumbersome parts management.
Innovation Solution
A terminal block design featuring a busbar assembly with separately formed housings and busbars, allowing for flexible configuration by changing the shape of either the busbar or housing to accommodate different device types, and a detachable holding portion for easy assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If terminal blocks are integrally formed with housings to match specific device configurations, then the terminal blocks can be precisely fitted to specific devices, but the number of different terminal block types increases, making parts management cumbersome
Solution Approach 1:
The terminal block is divided into two independent parts: a housing and a busbar assembly. The housing is separately formed and can be universally fitted to different devices, while the busbar assembly is separately configured to match specific device terminal positions. This segmentation allows the housing to be standardized across device types, reducing the number of housing variants needed.
Solution Approach 2:
The housing is designed with universal adaptability to fit multiple device types through standardized mounting interfaces. By separating the housing from the device-specific busbar configuration, the same housing can serve multiple device types, reducing the variety of housings needed while maintaining precise terminal connections through customized busbar assemblies.
2Adaptability or versatility
If terminal blocks are custom-designed for each device type, then the terminal blocks can accommodate different mounting hole shapes and terminal positions, but the variety of terminal block types increases, complicating inventory management
Solution Approach 1:
The terminal block system is segmented into a universal housing component and a device-specific busbar assembly. The housing maintains consistent mounting features across all device types, while the busbar assembly varies to match specific terminal positions and configurations, allowing standardized inventory management of housings while accommodating device diversity through modular busbars.
Solution Approach 2:
The invention merges the universal housing design with customizable busbar assemblies to create an adaptable terminal block system. By combining a standardized housing that can mount on various devices with configurable busbar assemblies, the system achieves broad device compatibility without requiring unique terminal blocks for each device type.
3Ease of manufacture
If the housing and busbar are separately formed, then the busbar can be easily repositioned to accommodate different terminal positions, but additional assembly steps are required
Solution Approach 1:
The busbar assembly is pre-configured with the busbar positioned and fixed within the housing at the appropriate terminal positions before the terminal block is installed on the device. This preliminary assembly of the busbar within the housing structure allows for easy repositioning and customization while reducing on-site assembly complexity, as the busbar is already secured in its final position within the housing.
