Electrical Connector Guide Frame Limiting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors risk damaging chip modules due to excessive rotation of the guide frame, which can cause impact with the pressing plate, leading to potential damage.
Innovation Solution
The electrical connector design includes a guide frame with a limiting section and engaging portion that prevents excessive rotation by abutting the limiting section when the guide frame opens, creating a gap between the guide frame and pressing plate, allowing safe chip module removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide frame is allowed to rotate freely between the base and pressing plate, then the chip module can be easily inserted and removed, but the guide frame may rotate excessively and impact the pressing plate, causing damage to the chip module
Solution Approach 1:
The patent applies preliminary anti-action by providing a limiting section on the guide frame that proactively prevents excessive rotation before impact can occur. The limiting section engages with the base at a predetermined position during rotation, creating a mechanical stop that counteracts the harmful rotational motion before it can damage the pressing plate or chip module.
Solution Approach 2:
The patent implements preliminary action by designing the limiting section to engage with the base before the guide frame can rotate into a harmful position. This pre-established mechanical constraint ensures that the guide frame's rotation is naturally limited to a safe range, preventing impact with the pressing plate before it can occur.
2Device complexity
If the guide frame structure is simplified without limiting mechanisms, then the device complexity is reduced, but the risk of excessive rotation and chip module damage increases
Solution Approach 1:
The patent applies segmentation by dividing the guide frame into functional sections: the limiting section that engages with the base to prevent excessive rotation, and the carrier assembly section that holds the chip module. This segmentation allows the limiting function to be integrated into the guide frame structure itself rather than requiring a separate limiting mechanism, thus reducing overall device complexity while maintaining safety.
Solution Approach 2:
The patent merges the limiting function directly into the guide frame structure by forming the limiting section as an integral part of the guide frame. This combination eliminates the need for separate limiting mechanisms or additional components, reducing device complexity while effectively preventing excessive rotation and protecting the chip module from impact.

AI summary
An electrical connector includes an insulating body. Multiple terminals are accommodated in the insulating body. A base is located at a periphery of the insulating body and provided with a first pivoting portion and a second pivoting portion, both located behind the insulating body. A guide frame is pivotally connected to the first pivoting portion, so that the guide frame rotates between a closed position and an open position relative to the base. The guide frame is provided with a limiting section, and two sliding rails are arranged at left and right sides thereof correspondingly. A carrier is supported on upper surfaces of the slide rails, slides in the sliding rails and rotates along with the guide frame. When the guide frame rotates from the closed position to the open position, an engaging portion abuts the limiting section to limit the guide frame from continuing rotating.
