Preloaded Connector Latch Audible Click and Permanent Set
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector latches lack an audible 'click' sound for complete mating assurance, are prone to permanent set due to compression, and have dimensional control issues, especially in automotive connectors.
Innovation Solution
A preloaded connector latch is manufactured in an undeflected position and subjected to a pre-mating deflection process, enhancing the 'click' sound, resisting permanent set, and ensuring good dimensional control through additional force and overstress protection features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the connector latch is manufactured in an undeflected position without preloading, then the manufacturing process is simpler, but the 'click' sound is not loud enough and dimensional control is poor
Solution Approach 1:
The connector latch is preloaded during manufacturing by deflecting it from its undeflected position to a preloaded position before final assembly. This preliminary action ensures that the latch is already in the optimal deflected state, providing better dimensional control and louder click sound without requiring complex adjustments during assembly or operation.
2Reliability
If the connector latch is designed without overstress protection features, then the profile is lower and the structure is simpler, but the latch is prone to permanent set under compression
Solution Approach 1:
The connector latch incorporates overstress protection features that are pre-configured to absorb and distribute compressive forces before they can cause permanent deformation. These features act as a cushioning mechanism built into the latch structure, protecting against permanent set while maintaining a relatively compact profile through optimized geometry.
3Ease of manufacture
If the latching features are not in a preloaded condition, then the device structure is simpler, but the 'click' sound is not loud enough for complete mating assurance
Solution Approach 1:
The latching features are preloaded during the manufacturing process, placing them in a preloaded condition before final assembly. This preliminary loading ensures that when the connector mates, the latching features engage with sufficient force to produce a loud, clear click sound that provides reliable auditory confirmation of complete mating, while the preload is achieved through a straightforward manufacturing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The preloaded connector latch provides an extra loud 'click' sound for complete mating assurance, maintains a low profile without overstress protection gaps, and is resistant to permanent set, ensuring reliable operation even in compressed or hot environments.
Implementation Method 1
the connector latch is then subjected to a pre-mating deflection process, in order to deflect the connector latch and lock the connector latch in a preloaded position

AI summary
Connector latch used to securely hold together a connector apparatus, such that the connector apparatus has at least a first connector assembly and a second connector assembly which can be mated together. Initially, after the connector latch is manufactured, the connector latch is in an undeflected position. After manufacture, the connector latch is subjected to a pre-mating deflection process, in order to move the connector latch into a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in the preloaded position. The preloaded connector latch provides a number of desirable characteristics, including at least an extra loud "click" sound when the first connector assembly and the second connector assembly are mated together.
