PCB Connector Separator Using Segmented Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies face challenges in safely unmounting mated connectors without applying excessive stress on the printed circuit boards, as the retention force between mated connectors is significant and requires substantial separation force.
Innovation Solution
A separator system with first and second separation members, each featuring separation posts that extend through apertures in the printed circuit boards, applies a compressive force to separate the connectors, overcoming the retention force and allowing the boards to unmate without stressing the circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a distributed force is applied to separate the mated electrical connectors, then the connectors can be unmounted, but excessive stress is applied to the printed circuit boards
Solution Approach 1:
The separator device is divided into multiple separation members (first separation member and second separation member), each with multiple separation posts distributed across the connector interface. This segmentation distributes the separation force across multiple localized points rather than applying a single concentrated force, enabling effective connector separation while minimizing stress on the printed circuit boards.
Solution Approach 2:
The separator acts as an intermediary device between the two mated electrical connectors. The separation members with separation posts are inserted between the mating interfaces of the first and second electrical connectors, providing a mechanical lever arm that amplifies the separation force while protecting the connectors and boards from direct stress.
2Force
If substantial separation force is applied to overcome retention force, then the connectors can be unmounted, but damage risk to the electrical assembly increases
Solution Approach 1:
The separator introduces a spatial dimension to the separation process by using separation posts that extend between the mating interfaces of the connectors. The separation members are positioned in the gap between the first and second substrates, creating a mechanical advantage through the vertical dimension. This allows substantial separation force to be generated while the force is distributed across multiple posts, reducing the risk of damage to the electrical assembly.
Solution Approach 2:
The separation force is segmented into multiple discrete application points through the use of multiple separation posts on each separation member. Instead of applying one large force that could damage the assembly, the total separation force is divided into many smaller forces applied at different locations, maintaining assembly integrity while achieving effective unmounting.
3Reliability
If the connectors are firmly mated to ensure reliable electrical connection, then connection reliability is improved, but the retention force requires excessive force for separation
Solution Approach 1:
The separator serves as a mechanical intermediary that leverages the existing retention force structure. The separation members with multiple posts are inserted between the mating connectors, using the retention force engagement points as leverage anchors. This allows the system to maintain firm mating for reliable connection while enabling controlled separation through the intermediary separator mechanism.
Solution Approach 2:
The separator exploits the vertical dimension between the first and second substrates to create mechanical advantage. The separation posts extend into the gap space, and the separation members are positioned to apply force at multiple heights and locations. This dimensional approach allows the system to maintain strong horizontal retention for reliable connection while enabling vertical separation force application that overcomes the retention force without excessive stress.
