Conductor Terminal Double Latching Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor terminals face instability and deformation under external forces due to inadequate locking mechanisms, leading to potential disassembly and functional impairment.
Innovation Solution
A conductor terminal design featuring a second latching connection between the closure part and contact insert, combined with a blocking element in the insulating housing, provides a preassembled, stable unit with enhanced security against deformation and disassembly by double latching mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single locking connection is used between the closure part and insulating housing, then the device complexity is reduced, but the stability and reliability under external forces deteriorates
Solution Approach 1:
The locking mechanism is segmented into two independent locking connections: a first locking connection between the closure part and insulating housing, and a second locking connection between the closure part and contact insert. This segmentation allows each locking connection to perform a specific stabilizing function, preventing deformation in different directions and improving overall reliability without significantly increasing complexity.
2Reliability
If a second locking connection is added between the closure part and contact insert, then the stability under external forces is improved, but the device complexity increases
Solution Approach 1:
The second locking connection merges the closure part, contact insert, and insulating housing into a unified pre-assembled unit. By combining these components through the second locking connection, the system achieves enhanced stability under external forces while maintaining a relatively simple overall structure, as the locking mechanisms work together synergistically.
3Object-affected harmful factors
If the blocking element is designed to prevent release of the second locking connection, then the resistance to disassembly is improved, but the ease of operation deteriorates
Solution Approach 1:
The blocking element is designed to prevent unauthorized release of the second locking connection under normal operating conditions. However, during proper assembly operations, the blocking element can be temporarily overcome or disengaged, allowing controlled assembly and disassembly. This preliminary anti-action protects against harmful unauthorized disassembly while maintaining ease of operation for legitimate assembly tasks.
