Modular Switch Wire Connection Device for Arc Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch wire connection devices require a larger operation space, necessitate bending conductive wires, and use of tools for assembly, leading to loosening issues and increased costs due to inability to replace individual modules, and often result in incorrect module arrangement causing electric arcs.
Innovation Solution
A modularized structure with an assembling support and detachable wire connection modules featuring enlarged plug-in holes and notches, allowing for easy assembly and disassembly, and enabling replacement of normally open (NO) and normally closed (NC) modules, enhancing insulation and preventing electric arcs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional switch wire connection device uses a screw mechanism for locking conductive wires, then the connection can be secured, but the operator requires a larger operation space and must use tools for tightening/untightening, making the operation troublesome
Solution Approach 1:
The patent replaces the traditional screw mechanism with a spring-loaded push-button system. The spring provides automatic locking force when the push-button is pressed, eliminating the need for tools and complex tightening operations while maintaining reliable electrical connection.
Solution Approach 2:
The spring-loaded mechanism automatically maintains connection pressure without requiring operator intervention for adjustment. The system self-regulates the locking force through the spring's elastic properties, making the connection process simpler and more reliable.
2Ease of manufacture
If the switch wire connection device uses a fixed integrated structure with pre-manufactured normally open (NO) and normally closed (NC) modules, then the device can be manufactured completely, but in case of failure the entire device must be replaced and the cost increases
Solution Approach 1:
The patent divides the switch wire connection device into separate, independently replaceable modules (NO modules and NC modules). Each module can be individually removed and replaced without affecting other parts of the device, enabling cost-effective repairs and reducing waste.
Solution Approach 2:
The modular design allows damaged modules to be discarded and replaced with new or refurbished modules. The remaining functional modules are recovered and continue to operate, reducing the need to replace the entire device and lowering maintenance costs.
3Adaptability or versatility
If the contact seat structure is used for arranging multiple electrical contact components, then the device can accommodate different modules, but the structure often causes electric arc of adjacent conductive components leading to unstable power transmission
Solution Approach 1:
The patent introduces insulating barriers or spacing structures between adjacent conductive components. These intermediary elements prevent direct electrical discharge between nearby contacts, eliminating electric arcs while maintaining the flexible arrangement of different module types.

AI summary
A modularized structure of switch wire connection device includes an assembling support and a wire connection module. The assembling support has a first side and a second side. The first and/or the second sides are formed with assembling sections for assembling with the wire connection module. The wire connection module includes a first wire connection module and/or a second wire connection module each having a case. The case defines a chamber for receiving and enclosing electrical contact components including conductive members. The case is formed with a mounting section for connecting with the assembling section of the assembling support. Accordingly, the wire connection module is detachably mounted on the assembling support as an integrated form. The modularized structure enables an operator to easily assemble/disassemble the components and change the switch specification between normally open mode and normally closed mode and enhance insulation effect to avoid electric arc.
