Plug Connector Locking Hooks for Contact Carrier Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connections face issues with the contact carrier moving out of its intended position during assembly or plug-in processes, leading to unreliable and error-prone connections.
Innovation Solution
The outer housing features obliquely aligned locking hooks with a counter-hook geometry that interact with the contact carrier, preventing it from being dislodged once inserted, ensuring secure positioning without hindering the insertion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking hooks with counter-geometry are added to secure the contact carrier, then the contact carrier positioning reliability is improved, but the device complexity increases
Solution Approach 1:
The locking hook and counter-geometry are integrated into the existing outer housing and contact carrier structures respectively, combining the locking function with the structural components rather than adding separate locking mechanisms. This merging approach improves positioning reliability while minimizing the increase in device complexity.
Solution Approach 2:
The locking hook and counter-geometry automatically engage when the contact carrier is inserted into the outer housing, providing self-locking functionality without requiring additional actuation or complex control mechanisms. The geometry of the locking hook and counter-geometry ensures automatic securing, improving reliability while keeping the device simple.
2Reliability
If the locking hook is oriented obliquely to prevent dislodgement, then the contact carrier security is improved, but the insertion process becomes more difficult
Solution Approach 1:
The locking hook is pre-oriented obliquely in the outer housing, and the counter-geometry is pre-formed on the contact carrier, so that during insertion the components naturally guide each other into the correct engagement position. This preliminary configuration ensures secure locking while maintaining ease of insertion, as the oblique orientation facilitates automatic alignment during the insertion process.
