Switch Assembly Plug-Based Connection for Compact Power Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch assembly installation and maintenance in power supply systems are cumbersome and inefficient, especially in small spaces, due to the need for cable connections and removals during switch replacement.
Innovation Solution
A switch assembly with a two-pin plug and circuit boards featuring female and male terminals allows for plug-based connections, simplifying installation and replacement by eliminating the need for cable connections, even in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two cables are used to connect the current input end and current output end of the switch to the power supply system, then the switch can be electrically connected to the power supply system, but the installation and maintenance operations become cumbersome and inefficient
Solution Approach 1:
The patent combines the current input end and current output end connections into a single integrated plug structure. The plug includes a first plug head for connecting to the current input end and a second plug head for connecting to the current output end, allowing both cable connections to be established simultaneously through one insertion action rather than requiring separate connections for each cable.
Solution Approach 2:
The switch assembly is divided into modular components: the switch body, the integrated plug with separate plug heads, and the power supply system with corresponding socket structures. This segmentation allows the plug to be designed as a standalone replaceable unit that maintains reliable electrical connections while simplifying installation and maintenance operations.
2Adaptability or versatility
If the switch needs to be replaced, then the cables need to be removed from two ends of the to-be-replaced switch and connected to two ends of a new switch, but this results in cumbersome operation and low efficiency
Solution Approach 1:
The patent merges the connection operations for both cables into a single plug insertion action. The integrated plug structure allows the technician to connect or disconnect both current paths simultaneously, eliminating the need to handle two separate cables during replacement operations and significantly improving replacement efficiency.
Solution Approach 2:
The plug is pre-assembled with both plug heads attached to the switch body before installation. This preliminary assembly ensures that when the switch needs to be replaced, the entire connection interface is already prepared as a complete unit, allowing for quick swap-out without requiring intermediate connection steps.
3Volume of moving object
If the installation or replacement operation needs to be performed in a small space having a height of 1 U, then the switch can be installed in compact equipment, but the operation difficulty increases
Solution Approach 1:
The patent combines multiple connection operations into a single plug insertion motion. This reduces the physical space and hand movement required during installation, as the technician only needs to perform one insertion action rather than manipulating multiple cables separately, making the operation feasible in compact 1 U height equipment spaces.

AI summary
A switch assembly and a power supply system are provided. The switch assembly includes a switch body having a two-pin plug, a first circuit board, and a second circuit board. The first circuit board is provided with a power supply terminal block and a group of female terminals. The group of female terminals includes a first female terminal, a second female terminal and a third female terminal. The first female terminal and the second female terminal are respectively plugged with two pins of the two-pin plug. The first female terminal is electrically connected to the power supply terminal block, and the second female terminal is electrically connected to the third female terminal. The second circuit board is provided with a load connection terminal and a male terminal electrically connected to the load connection terminal. The male terminal is plugged with the third female terminal.
