Adjustable Coaxial Connector Crimping Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connector crimping tools require multiple crimping elements for different types or standards of connectors, leading to high expenses and storage issues, and suffer from uneven force distribution causing stress concentration in the transmittal shaft.
Innovation Solution
A coaxial connector crimping tool with an adjustable transmittal shaft length and dual-layer storage for crimping elements, featuring a guiding structure and adjustable portion with screw and tapped hole mechanisms to accommodate various connector sizes and types, ensuring even force transfer and efficient storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple crimping elements are used for different connector types and lengths, then compatibility with various connectors is improved, but device complexity and storage requirements increase
Solution Approach 1:
The transmittal shaft is designed with an adjustable length mechanism, allowing it to be extended or retracted to accommodate different connector lengths. This dynamic adjustment capability enables a single crimping element to handle multiple connector types, eliminating the need for multiple specialized elements while maintaining full compatibility.
2Adaptability or versatility
If the transmittal shaft length is fixed, then device simplicity is maintained, but adaptability to different connector lengths is reduced
Solution Approach 1:
The transmittal shaft incorporates a telescopic structure with guide slots that allow it to dynamically change length. The guide slots provide a controlled path for the shaft segments to slide relative to each other, enabling smooth length adjustment while maintaining structural integrity and alignment during the crimping operation.
Solution Approach 2:
The transmittal shaft is divided into multiple segments that can move independently relative to each other. These segmented sections are connected through pivot points and guide slots, allowing the shaft to extend and retract in a controlled manner to match different connector lengths while keeping the overall structure manageable.
3Ease of operation
If force is applied along the handle direction, then ease of operation is improved, but force transfer efficiency to the transmittal shaft decreases due to misalignment
Solution Approach 1:
The linkage mechanism incorporates curved guide slots and pivoting joints that redirect the force vector. When the user applies force along the handle direction, the curved geometry of the guide slots and the rotational movement of the pivots work together to realign the force with the transmittal shaft's axis, maximizing force transfer efficiency while maintaining ergonomic operation.

AI summary
A coaxial connector crimping tool has a base, a handle, a transmittal unit and a crimping area. The base has a containment slot, and the containment slot has a guiding structure. One end of the handle is pivoted on an end of the base. Two ends of the transmittal unit are respectively pivoted on a first predetermined position of the guiding structure and a second predetermined position of the handle, and the transmittal unit has an adjustable length. The transmittal unit has an adjustable portion, and the adjustable portion is disposed between the first predetermined position and the second predetermined position. The crimping area is pivoted on the transmittal unit and disposed in the containment slot.
