Electrical Connector Latch Assembly for Secure Substrate Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector systems face challenges in efficiently supporting multiple connectors on a common printed circuit board while maintaining secure connections and efficient electrical communication.
Innovation Solution
The electrical connector assembly comprises a first connector mounted to a substrate with electrical contacts and a second connector supported by the first connector, secured to the substrate without direct electrical contact, allowing for secure attachment and efficient communication through a dielectric or insulative housing and engagement members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electrical connectors are mounted on a common printed circuit board, then electrical communication efficiency is improved, but connection stability deteriorates due to gravitational forces and alignment issues
Solution Approach 1:
The connector assembly is divided into separate components: a first connector mounted on the substrate, a second connector supported by the first connector, and independent engagement members. This segmentation allows each component to be optimized for its specific function while working together as a cohesive system, resolving the contradiction between supporting multiple connectors and maintaining connection stability.
Solution Approach 2:
The engagement members are designed to resist gravitational forces and maintain alignment between connectors. The latch assembly and complementary latch features create counteracting forces that prevent misalignment and ensure stable connections, directly addressing the reliability issue caused by gravity.
2Strength
If connectors are directly secured to the substrate, then connection strength is improved, but device complexity increases due to additional mounting requirements
Solution Approach 1:
The second connector is supported by the first connector, creating a nested arrangement where the second connector is held by the first connector rather than requiring direct substrate mounting. This nesting reduces mounting complexity while maintaining connection strength through the engagement members that secure the nested structure.
Solution Approach 2:
The first connector serves multiple functions: it provides electrical connection, supports the second connector mechanically, and works with engagement members to secure both connectors to the substrate. This multi-functionality reduces the need for separate mounting mechanisms, simplifying the overall device while maintaining strength.
3Ease of operation
If connectors are designed for easy attachment and detachment, then ease of operation is improved, but connection reliability deteriorates
Solution Approach 1:
The latch assembly incorporates movable components that transition between engaged and disengaged states. The latch member can move to lock the connectors together securely, while also allowing easy release when needed. This dynamic design provides both ease of operation and reliable connection through the same mechanism.
Solution Approach 2:
The engagement members and latch assembly provide mechanical feedback that confirms proper engagement. When connectors are correctly attached, the latch features engage and provide tactile or visual confirmation, ensuring reliability. The same mechanism allows easy detachment when the latch is released, maintaining ease of operation.

AI summary
Methods and apparatus are disclosed for supporting first and second electrical connectors on a substrate. For instance, the first electrical connector includes electrical contacts that are configured to be mounted to the substrate. The second electrical connector includes electrical contacts that are configured to be mounted to a complementary electrical component other than the substrate. The second electrical connector is thus configured to be attached to the first electrical connector, such that the second electrical is supported by the substrate without being mounted to the substrate.
