Electric Wire Clip Rotating Shaft Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wire clips often have pressing arms that are integrally formed with the housing, leading to frequent breakage when the wire is pulled away, rendering the device non-functional.
Innovation Solution
A rotating shaft and pressing arm mechanism that allows the pressing arm to hinge with the housing, enabling downward rotation to disengage the clamping piece and facilitate wire removal without breaking, with additional features like limiting protrusions and reinforcing ribs for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pressing arm and housing are integrally formed, then the structure is simple, but the pressing arm breaks frequently during repeated use
Solution Approach 1:
The pressing arm is separated from the housing by introducing a rotating shaft as an independent component. The pressing arm can now rotate relative to the housing around the rotating shaft, transforming from a fixed integral structure to a segmented movable structure. This segmentation allows the pressing arm to withstand repeated operational stresses without breaking.
Solution Approach 2:
The pressing arm transitions from a static fixed structure to a dynamic movable structure by enabling rotation around the rotating shaft. This dynamic capability allows the pressing arm to adapt to operational forces and repeated use, significantly improving durability while maintaining structural simplicity.
2Ease of operation
If the pressing arm is pressed down to disengage the wire, then wire removal is facilitated, but the pressing arm may break without proper structural support
Solution Approach 1:
The rotating shaft serves as an intermediary element between the pressing arm and the housing. It provides a hinge connection that supports the pressing arm during downward movement, distributing the mechanical stress and preventing breakage while enabling smooth wire disengagement operation.
Solution Approach 2:
The rotating shaft is pre-installed to provide structural support and cushioning to the pressing arm before operational forces are applied. This beforehand support prevents the pressing arm from breaking during repeated wire insertion and removal operations.

AI summary
The present disclosure provides an electric wire clip, which includes a housing, a contact member and a pressing mechanism. The housing is provided with a mounting passage and an inserting hole communicating with the mounting passage. The pressing mechanism includes a pressing arm and a rotating shaft disposed on the pressing arm and hinged with the housing. In operation, the wire can pass through the inserting hole and be engaged with the clamping protrusion. When the wire needs to be pulled away, the driving pressing arm is rotated downwardly, and the first hook is swung downwardly to be engaged with the clamping protrusion. When rotating downwardly, the pressing arm is able to abut and drive the clamping piece to move outwardly, so that the clamping piece disengages from the wire to facilitate pulling away the wire.
