Solution Overview
Problem
The terminals of voltage sensing lines can move freely and interfere with other components during connection to a busbar module, posing a risk of damage or malfunction.
Innovation Solution
A connection module with an insulation protector that includes a terminal holding part to removably hold the terminals until connection, featuring a busbar installation wall with integral terminal connection parts and elastic retaining pieces to guide and secure the terminals during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminals are left free before connection, then ease of connection is improved, but risk of interference with other components increases
Solution Approach 1:
The terminal holding part preliminarily positions the terminal in a safe location before the connection operation is completed. The holding part restricts the terminal's movement during the connection process, preventing interference with other components while maintaining ease of connection through the simple act of placing the terminal into the holding part.
Solution Approach 2:
The terminal holding part acts as an intermediary between the terminal and other components. It provides a temporary holding position that mediates between the need for terminal freedom during connection and the need to prevent interference, allowing the terminal to be safely positioned until the connection is complete.
2Object-affected harmful factors
If terminals are constrained during assembly, then interference with other components is prevented, but assembly complexity increases
Solution Approach 1:
The terminal holding part is designed as a simple, separate component integrated into the insulation protector. It segments the terminal positioning function from the main connection structure, providing a dedicated holding position without complicating the overall assembly. The holding part uses simple geometric features like recesses or protrusions rather than complex mechanical constraints.
Solution Approach 2:
The terminal holding part is designed to be self-aligning and self-retaining through its geometric features. The terminal naturally fits into the holding part's recess or is retained by simple protrusions, eliminating the need for additional fastening mechanisms or complex alignment procedures. This self-service design prevents interference while maintaining assembly simplicity.
