Link Member Electrical Connector Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As computing devices become smaller, the limited space makes it difficult for users to access and remove circuit boards from electrical connectors without removing neighboring components, increasing the difficulty of ejection.
Innovation Solution
An electrical connector design featuring a link member that facilitates the rotation of latches to eject a circuit board, allowing for single-handed ejection by sliding the link member across the body to rotate the second latch, thus reducing the complexity of the ejection process.

Engineering Contradiction Analysis
1Volume of moving object
If manual ejection mechanism is used in compact devices, then device size is reduced, but user accessibility and ejection ease deteriorate
Solution Approach 1:
The link member acts as an intermediary mechanical element that transmits the ejection force from the first latch to the second latch. When the first latch rotates, it pushes the link member, which in turn pushes the second latch to rotate, enabling coordinated ejection of both latches without requiring direct user manipulation of each latch individually.
2Reliability
If multiple latches are used to secure circuit board, then connection reliability is improved, but ejection complexity increases
Solution Approach 1:
The link member merges the ejection operations of two separate latches into a single coordinated action. By physically coupling the latches through the link member, the system combines what would otherwise be two independent manual operations into one unified ejection motion, reducing operational complexity while maintaining the security benefits of dual latches.

AI summary
An example electrical connector includes a body to receive a circuit board. The body includes a first end and a second end. The electrical connector also includes a first latch rotatably attaches to the first end. The electrical connector further includes a second latch rotatably attaches to the second end. The electrical connector further includes a link member attached to the body. In response to a rotation of the first latch, the link member is to slide across the body from the first latch towards the second latch to rotate the second latch.
