Connector Anti-off Part Prevents Hot-plug Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors in electronic devices face disconnection issues when 'hot-plugged', leading to instantaneous high voltage or high current, which can damage electrical components and affect operational reliability and service life.
Innovation Solution
A connector with an anti-off part that generates an adsorption force to keep terminals connected when energized, using magnetic or electromagnetic components that switch between adsorption and failure states based on power status, preventing disconnection and ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector allows quick connection and separation, then the ease of operation is improved, but the reliability deteriorates due to hot-plugging disconnection
Solution Approach 1:
The connector employs a dynamic locking mechanism that changes state based on power status. When power is detected, the locking structure transitions from a releasable state to a locked state, preventing disconnection. This dynamic behavior allows the connector to adapt its mechanical properties according to operational conditions, maintaining both ease of operation during unpowered states and reliability during powered states
Solution Approach 2:
The connector incorporates a feedback mechanism that detects the power status and responds by adjusting the locking mechanism's state. The detection module monitors whether power is applied, and this information feeds back to the locking structure, which automatically engages or disengages accordingly. This closed-loop control ensures the connector remains locked during powered operation while allowing easy connection and separation when unpowered
2Adaptability or versatility
If the connector enables hot-plugging, then the adaptability is improved, but harmful factors increase due to instantaneous high voltage or current
Solution Approach 1:
The connector implements preliminary protective actions by detecting the power status before allowing connection or separation. When power is detected, the locking mechanism proactively engages to prevent hot-plugging operations that could cause instantaneous high voltage or current. This preventive measure blocks harmful operations before they can occur, protecting the electrical components from damage while still allowing safe hot-plugging when unpowered

AI summary
Disclosed are a connector, a display screen, and an electronic device. The connector includes a first connection end, a second connection end, and an anti-off part. The second connection end is detachably connected to the first connection end; the anti-off part is configured to restrict the first connection end and the second connection end from being separated from each other and disconnected when the first connection end and the second connection end are energized and conductive.
