Crimping Hand Tool Toggle Linkage Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crimping tools for coaxial cables are inconvenient and risk losing the crimping portion due to the need to adjust and reposition the crimping mechanism for different terminal specifications, leading to inefficiencies and potential loss.
Innovation Solution
A crimping hand tool with a toggle joint linkage structure that allows for adjustable crimping of coaxial cables and terminals, featuring a moving assembly driven by a toggle joint linkage, a crimping assembly, and a locking mechanism to accommodate various terminal sizes without requiring manual repositioning of the crimping portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the crimping portion is pulled out and repositioned to accommodate different terminal specifications, then adaptability to different terminal sizes is improved, but ease of operation deteriorates due to inconvenience and risk of losing the crimping portion
Solution Approach 1:
The crimping portion is made movable along the handling direction through a sliding structure with guide grooves and guide posts. This allows the crimping portion to dynamically adjust its position to accommodate different terminal specifications while remaining attached to the tool, eliminating the need to pull it out and reattach it. The sliding mechanism maintains ease of operation by keeping the crimping portion securely connected during adjustment.
Solution Approach 2:
The tool is designed with a universal crimping mechanism that can accommodate multiple terminal specifications through position adjustment. The crimping portion can be positioned at different locations along the handling direction to match different terminal sizes, making the tool versatile for various coaxial cable terminals without requiring multiple dedicated crimping portions or tool replacements.
2Adaptability or versatility
If the crimping portion is pulled out and repositioned for different specifications, then adaptability is improved, but loss of time occurs due to repeated replacement actions
Solution Approach 1:
The dynamic sliding mechanism allows the crimping portion to be quickly repositioned along the handling direction by simply sliding it to the appropriate position, rather than requiring the user to pull it out and reattach it. This significantly reduces the time needed to adapt to different terminal specifications while maintaining full adaptability.
Solution Approach 2:
The crimping portion remains continuously attached to the tool throughout the adjustment process, eliminating the interruption caused by removal and reattachment. The sliding mechanism allows for continuous adjustment without breaking the connection, thereby reducing time loss and maintaining operational continuity.
3Adaptability or versatility
If the crimping portion is pulled out and repositioned, then adaptability to different specifications is improved, but reliability deteriorates due to risk of losing the crimping portion
Solution Approach 1:
The crimping portion is designed to slide along the handling direction within guide grooves and guide posts, allowing position adjustment while maintaining secure attachment. This dynamic connection ensures the crimping portion cannot be lost during adjustment, as it is constrained by the guiding structure that keeps it connected to the tool body.
Solution Approach 2:
The guide grooves and guide posts act as intermediary structures that mediate between the crimping portion and the tool body. These intermediaries provide a secure mechanical connection that allows movement while preventing loss, ensuring the crimping portion remains reliably attached during position changes for different terminal specifications.
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
Facilitates efficient crimping of coaxial cables and terminals with different specifications by enabling the crimping assembly to adjust automatically, reducing user inconvenience and minimizing the risk of losing the crimping portion, while ensuring secure connections.
Implementation Method 1
The first linking body and the second linking body are respectively a toggle joint structure, the toggle joint structure of the first linking body being pivoted to the third linking body, the toggle joint structure of the second linking body being pivoted to the first linking body
Implementation Method 2
The first return spring is connected between the moving assembly and the first pivoting shaft, the first return spring constantly driving the first body and the second body to be oppositely opened
