Rotating Hook Connector Lock for Heat-Stable Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for connecting circuit boards in display devices are prone to disconnecting due to deformation when subjected to the heat generated by cables, causing the cables to disconnect.
Innovation Solution
The connector includes a case with a rotatably disposed in the actuator that includes a hook extending from the actuator, and a locking portion in which the hook is inserted when the actuator rotates to close the case, and a locking portion in which the hook is inserted to prevent disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the connector is subjected to heat generated from the cable, then the connector deforms, but the cable disconnection risk increases
Solution Approach 1:
The locking mechanism transitions from a linear engagement to a rotational engagement. The actuator rotates to move the hook from an open position to a locked position, engaging with the locking portion in a different spatial dimension. This rotational motion allows the hook to securely engage the locking portion, preventing disconnection even when thermal deformation occurs in the original engagement direction.
2Ease of manufacture
If a simple connector structure is used, then manufacturing is easier, but the connector cannot prevent disconnection under heat deformation
Solution Approach 1:
The connector incorporates a dynamic locking mechanism with a rotatable actuator that transitions between open and locked states. The hook on the actuator dynamically engages with the locking portion on the case, providing active security against disconnection. This dynamic element allows the connector to adapt to thermal deformation while maintaining reliable connection.
Solution Approach 2:
The hook and locking portion serve as intermediary elements between the actuator and the case. The hook on the actuator mediates the locking action by engaging with the locking portion recessed in the case. This intermediary mechanism transfers the rotational motion of the actuator into a secure mechanical lock that prevents cable disconnection under thermal stress.

AI summary
A connector includes a case in which an open area is formed, and an actuator rotatably disposed in the open area of the case to open and close at least a portion of the open area through the rotation, wherein the actuator comprises a hook extending from the actuator in a direction perpendicular to a direction to which a rotation axis extends, and wherein the case comprises a locking portion in which the hook is inserted when the actuator closes at least the portion of the open area through the rotation.
