Connector Assembly Latching Mechanism for Airbag Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection devices for airbag systems require latching elements to be designed specifically for each socket element type, making the connection process complex and unreliable due to dependencies on socket shape and size.
Innovation Solution
A connector assembly with a plug element and a latching element that moves between two latching positions, where the latching element engages with a short-circuiting piece to remove the short-circuit state and ensure a reliable connection without depending on the socket element's shape, using a simple construction that allows for easy operation and prevention of deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the latching element is designed specifically for each socket element type to ensure reliable engagement, then the connection reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The latching element is designed with a universal structure that can engage with different socket element types without requiring custom design for each type. The element features a standardized body with adaptable engagement mechanisms that work across multiple socket configurations, eliminating the need for type-specific variants while maintaining reliable connection.
Solution Approach 2:
The latching element is divided into distinct functional segments: a body portion for insertion, engagement portions for securing to the socket, and a pushed portion for actuation. This segmentation allows each part to be optimized independently while maintaining overall compatibility across different socket types, simplifying both design and manufacturing.
2Strength
If the latching element engages deeply with the socket element to prevent separation, then the mechanical strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The latching element incorporates elastic or resilient features that allow dynamic adjustment during insertion. The element can flex during the insertion process to accommodate slight misalignments and then settle into a secure engaged position, providing both ease of insertion and strong mechanical engagement without requiring excessive force.
3Reliability
If the short-circuiting piece is moved to non-short-circuit position only after complete engagement, then the safety is improved, but the connection time increases
Solution Approach 1:
The short-circuiting piece is positioned in advance within the latching element structure, ready to be deployed automatically upon engagement. The element's design ensures that the short-circuiting function is activated as part of the engagement sequence, eliminating the need for separate manual intervention and reducing overall connection time while maintaining safety.

AI summary
A connector 8 includes a plug element 3, a short-circuiting element 4, and a latching element 50 to be latched at a first latching position and a second latching position. When the latching element 50 is at the second latching position, a short-circuiting piece 4m moves to a non-short-circuit position. The latching element 50 has latch portions 52 formed in a projecting manner, and the short-circuiting element 4 has latch receiving portions 41a. In a state where the plug element 3 is inserted into the socket element 2i, when the latching element 50 is at the second latching position, the latch portions 52 and the latch receiving portions 41a engage with each other to prevent separation between the socket element 2i and the plug element 3.
