Electrical Connector Latch Secured to Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies lack sufficient securement mechanisms, particularly in ensuring the latches are firmly attached to both the connector housing and internal substrate, which can lead to instability and potential disconnection during use.
Innovation Solution
The electrical connector assembly features a pair of latches secured to the connector housing in a cantilevered fashion with an arm attached to the substrate, incorporating a shielding shell and slits on the substrate for enhanced securement through soldering, ensuring the latches and shielding shell are firmly grounded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If latches are secured to connector housing in a cantilevered fashion only, then the structure is simpler and easier to manufacture, but the securement and stability are insufficient leading to potential disconnection
Solution Approach 1:
The latch structure is merged with the substrate by securing the latch arm to the substrate, combining two separate securing functions (housing attachment and substrate attachment) into a unified latch assembly that provides both structural support and electrical connection
Solution Approach 2:
The securing mechanism transitions from a single-plane cantilevered attachment to a multi-dimensional configuration where the latch is secured to both the connector housing and the internal substrate, adding a second attachment plane and significantly enhancing stability
2Reliability
If latches are secured to both connector housing and internal substrate, then the securement and stability are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The latch assembly is segmented into distinct functional portions: a body portion that secures to the connector housing and an arm portion that secures to the substrate, allowing each portion to be optimized and assembled independently while maintaining overall stability
