Cable Connection Box Overvoltage Protection Module Pin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable junction boxes for light poles require complex cabling and large spaces for overvoltage protection modules, making installation and handling cumbersome and prone to incorrect connections.
Innovation Solution
A compact overvoltage protection module with rigid connecting pins that directly engage with the output terminals of the connection block, eliminating the need for complex cabling and allowing for a flush, space-saving installation, and ensuring correct connections through fixed pin alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard overvoltage protection modules with cable connections are used, then electrical connection can be achieved, but the housing must be dimensioned very large and installation becomes complex
Solution Approach 1:
The overvoltage protection module is nested directly into the connection block housing, with the protective device integrated inside the same housing space. This eliminates the need for separate external modules and large housing dimensions, as the protection function is embedded within the existing structural boundaries.
Solution Approach 2:
The overvoltage protection module and connection block are merged into a single integrated unit. The protective device is combined with the connection block structure, sharing common housing and mounting space, thereby eliminating the need for separate large-dimensional housings for each component.
2Reliability
If standard overvoltage protection modules with cable connections are used, then electrical connection can be achieved, but installation and handling become cumbersome
Solution Approach 1:
The connection pins are pre-positioned and pre-aligned on the overvoltage protection module before installation. This preliminary positioning ensures that when the module is installed, the electrical connections are automatically established without requiring complex manual cabling or alignment procedures during installation.
Solution Approach 2:
The complex cabling and wiring operations are extracted and eliminated from the installation process. Instead of requiring manual cable routing and connection during installation, the patent uses pre-configured connection pins that establish electrical contacts automatically upon module installation, simplifying the installation procedure.
