Sliding-Handle Wiring Terminal for Secure Repeated Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring terminals often experience wire loosening due to misoperation, especially during repeated wire drawing or plugging, which can be painful and labor-intensive for wiring staff, and lack a compact design due to rotary handle mechanisms.
Innovation Solution
A wiring terminal design featuring a handle that slides along a track, using an elastic piece deformed by the handle to create a gap for wire insertion or removal, with inclined surfaces for secure engagement and tool-assisted operation to prevent misoperation, eliminating the need for a rotary mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotary operation handle is used to deform the elastic piece, then the wiring terminal can achieve wire connection and teardown, but the wires may loosen due to misoperation and the structure becomes complex
Solution Approach 1:
The patent inverts the conventional rotary operation into a linear sliding operation. The handle slides along a sliding track rather than rotating, which fundamentally changes the operation mode. This inversion prevents misoperation because the linear sliding motion is more intuitive and less prone to incorrect execution compared to rotary motion, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The patent changes the motion parameter from rotational to linear sliding. The handle moves along a predetermined sliding track in a linear fashion, which simplifies the operation and reduces the complexity of the mechanism. This parameter change also makes the operation more reliable as linear motion is easier to control and less prone to misoperation than rotary motion.
2Ease of operation
If a rotary handle mechanism is adopted, then the elastic piece can be deformed to control gap size, but the device complexity increases
Solution Approach 1:
The patent replaces the complex rotary handle mechanism with a simpler linear sliding mechanism. The handle slides along a sliding track to deform the elastic piece, eliminating the need for rotary joints and associated complexity. This inversion maintains the ability to control gap size while significantly reducing device complexity.
Solution Approach 2:
The patent extracts the essential function of handle operation (deforming the elastic piece) from the complex rotary mechanism and implements it through a simpler linear sliding motion along a track. This extraction removes unnecessary mechanical complexity while preserving the core functionality of gap size control.
3Productivity
If repeated wire drawing or plugging is performed manually, then the wiring work can be completed, but user fatigue increases and labor intensity is high
Solution Approach 1:
The patent implements self-service through the elastic piece that automatically returns to its original state after deformation. When the handle slides to deform the elastic piece for wire insertion, the elastic piece naturally rebounds when the handle is released, automatically creating the gap needed for wire removal. This self-service mechanism eliminates the need for manual repositioning operations, reducing user fatigue and increasing productivity for repeated wiring tasks.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents wire loosening, reduces user fatigue, and simplifies installation by eliminating the rotary handle, resulting in a more convenient, durable, and compact wiring terminal.
Implementation Method 1
when the handle is in a first position, the elastic piece resists the conductive member under an acting of an elastic force; and when the handle moves from the first position to a second position along a sliding track, the handle acts on the elastic piece to deform the elastic piece
Implementation Method 2
the first inclined surface and the second inclined surface are matching fitted, to resist against an acting of an elastic restoring force and hold the handle at the second position

AI summary
The present disclosure relates to the field of electrical technology and provides a wiring terminal. The wiring terminal includes: a conductive member, an elastic piece and a handle; when the handle is in a first position, the elastic piece resists the conductive member under an acting of an elastic force; and when the handle moves from the first position to a second position along a sliding track, the handle acts on the elastic piece to deform the elastic piece, and separate from the conductive member to form a gap for facilitating a wire drawing or a wire plugging. Compared with the existing wiring terminal with a rotary wrench, a wiring terminal provided in the present embodiment may use a tool to drive a handle to move, which may effectively avoid the case where the wire is loosened due to the misoperation causing the open of the handle after the wire is connected; especially in the case where a repeated wire drawing or wire plugging is needed, the use of the tool is labor-saving, and the wiring staff's hands will not be painful due to the need to repeatedly pull the handle.
