Electrical Terminal Damping Section for Wire Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connection terminals are laborious to operate, prone to damage during use, and hinder the extraction of conductive wires due to the metal leaf spring's interference when released, especially with larger diameter wires.
Innovation Solution
The electrical connection terminal structure incorporates a latch member to stabilize the metal leaf spring's pressing action, an elastic unit to facilitate smooth release of the conductive wire, and a damping section to reduce collision force, allowing easy extraction and inspection without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the metal leaf spring is used to press the conductive wire for electrical connection, then the electrical connection is reliable, but the conductive wire cannot be easily extracted when the shift member is released
Solution Approach 1:
The patent introduces a damping section that dynamically controls the movement of the metal leaf spring. When the shift member is released, the damping section gradually slows down the metal leaf spring's return motion, preventing it from rapidly interfering with the conductive wire. This dynamic control allows the conductive wire to be easily extracted while maintaining reliable electrical connection during operation.
Solution Approach 2:
The damping section is positioned in advance to cushion the return motion of the metal leaf spring. Before the metal leaf spring can interfere with the conductive wire extraction, the damping section provides friction-based resistance to slow down its movement, thereby preventing harmful interference and enabling easy wire extraction.
2Reliability
If the shift member is pressed to force the metal leaf spring to bite the conductive wire, then the electrical connection is stable, but the terminal is prone to damage during use
Solution Approach 1:
The damping section is pre-positioned to provide friction-based cushioning during the shift member's operation. When the shift member is pressed to force the metal leaf spring to bite the conductive wire, the damping section gradually slows down the motion, preventing sudden impacts and excessive forces that could damage the terminal structure.
Solution Approach 2:
The damping section acts as an intermediary between the shift member and the metal leaf spring. It provides friction-based resistance that mediates the force transmission, allowing the metal leaf spring to maintain stable contact with the conductive wire while preventing excessive forces from damaging the terminal.
3Ease of operation
If the metal leaf spring is designed with complicated structure to cooperate with the shift member, then the pressing control is precise, but the device complexity increases
Solution Approach 1:
The patent extracts the complexity control function from the metal leaf spring structure itself and places it in the damping section. The metal leaf spring can maintain a simpler structure for pressing control, while the damping section handles the motion control and speed regulation, thereby reducing overall device complexity while maintaining precise pressing control.
Applied Scientific Principles
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 redesigned structure enables stable and effortless operation, prevents damage to the terminal, and allows easy extraction of conductive wires without auxiliary tools, while enabling external inspection for component integrity.
Implementation Method 1
an elastic unit mounted in the chamber. When the metal leaf spring is released from the pressing of the shift member to release the conductive wire from the pressing, the elastic unit normally makes the metal leaf spring and the shift member move toward a position where the conductive wire is released
Implementation Method 2
a damping section disposed in the chamber of the main body corresponding to the shoulder section of the shift member. When the shift member is operated and pushed upward, the damping section frictionally interferes with the shoulder section to slow down the speed by which the metal leaf spring elastically pushes the shift member

AI summary
An electrical connection terminal structure includes: a main body (10) defining a chamber (11); a metal leaf spring (30) disposed in the chamber (11), the metal leaf spring (30) being movable with the motion of a shift member (20) to press a conductive wire (50) into electrical connection or release the conductive wire (50); and an elastic unit (80, 90) mounted in the chamber (11). When the metal leaf spring (30) is released from the pressing of the shift member (20) to release the conductive wire (50) from the pressing, the elastic unit (80, 90) normally makes the metal leaf spring (30) and the shift member (20) move toward a position where the conductive wire (50) is released. This improves the shortcoming of the conventional electrical connection terminal that when released, the metal leaf spring (30) is apt to interfere with the conductive wire (50) and make it hard to extract the conductive wire (50) out of the main body (10).
