Crimping Hand Tool Pivoting Linkage for Multi-Core Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping tools are not efficiently designed to crimp multiple cores of a cable and a housing together to form a secure cable connector, lacking a mechanism for easy operation and effective engagement.
Innovation Solution
A crimping hand tool with a pivoting mechanism between two bodies, a linking member, and a crimping assembly that moves along a guiding structure to securely crimp the cable and housing, featuring a shaft with different diameters for engagement and a cutter for core management, allowing for efficient crimping and core cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional crimping tool design is used, then the structure is simple, but the crimping efficiency and ease of operation are poor
Solution Approach 1:
The crimping tool employs a dynamic pivoting mechanism where the second body can rotate relative to the first body about a pivot axis. This dynamic motion converts rotational movement into linear crimping force, improving crimping efficiency while maintaining a relatively simple overall structure. The linking member with slot and shaft combination enables this dynamic transformation without requiring complex mechanisms.
2Ease of operation
If a pivoting mechanism with linking member is added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The linking member acts as an intermediary element between the pivoting second body and the crimping assembly. It contains a slot that receives the shaft, translating the rotational pivoting motion into controlled linear movement of the crimping assembly. This intermediary mechanism simplifies the overall design by decoupling the pivoting motion from the crimping action, making the tool easier to operate without requiring overly complex direct coupling mechanisms.
3Reliability
If the shaft with different diameters is used for engagement, then the reliability of engagement is improved, but the manufacturing complexity increases
Solution Approach 1:
The shaft features local quality variation with different diameter sections along its length. The first section has a diameter matching the slot dimensions for engagement, while the second section has a different diameter for alternative engagement purposes. This local differentiation provides reliable multi-mode engagement without requiring entirely different shaft components, keeping manufacturing relatively simple while enhancing reliability and versatility.

AI summary
A crimping hand tool configured to crimp a cable and a housing. The crimping hand tool includes a first body having at least one guiding structure, a second body is pivoted to the first body to rotate with respect to each other to be unfolded and folded, a linking member is pivoted to the second body, and the linking member has a slot, a crimping assembly is pivoted to the linking member and is slidably coupled to the guiding structure, and a shaft is movably inserted in the first body and the slot of the linking member. After the housing and cores are placed into the first body, the second and first body are folded with respect to each other to drive the crimping assembly to move along the guiding structure through the linking member to crimp the housing and the cable together.
