Compact Crimping Tool With Inverted Rack And Gear Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crimping tools require significant space for operation, which limits their use in confined areas when connecting coaxial cables to electromechanical apparatuses.
Innovation Solution
A crimping tool design featuring a base with a pivot location, sliding groove, and dual fixing locations, along with an operating member and moving member equipped with a rack and gear mechanism, allowing for compact operation by enabling the moving member to move in opposite directions to press-fit connectors at different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the operating member and moving member face the same direction in conventional crimping tools, then the crimping function is achieved, but a sufficient space must be reserved for operation which increases the device's footprint
Solution Approach 1:
The patent inverts the conventional arrangement by making the operating member face opposite to the moving member direction. The operating member rotates in one direction to drive the moving member forward for crimping, then rotates back to return the moving member to initial position. This inversion allows bidirectional operation from a single fixed position, eliminating the need for sufficient reserved space while maintaining full crimping functionality.
2Length of stationary object
If the operating member rotates to drive the moving member in the same direction, then the mechanism is simple, but sufficient space must be reserved which increases the overall device size
Solution Approach 1:
The patent employs dynamic operation where the operating member rotates bidirectionally: rotating in a first direction drives the moving member forward to perform crimping, while rotating in a second direction returns the moving member to its initial position. This dynamic approach allows the same mechanism to serve dual purposes (forward crimping and reset) without increasing device length or requiring additional space-reserving structures.
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
Significantly reduces the operational space required, enabling efficient connection of coaxial cables in smaller spaces while maintaining effective press-fitting functionality.
Implementation Method 1
The rack is engaged with the gear of the operating member. Thus, when the operating member rotates, the gear drives the rack to enable the moving member to move simultaneously.
Implementation Method 2
The moving member is provided in the sliding groove so as to move in the sliding groove, and includes a rack, a first crimping element and a second crimping element. The rack is engaged with the gear of the operating member.
Implementation Method 3
The pivotal hole is pivotally connected to a pivot location of the base through a pivotal shaft.

AI summary
A crimping tool is disclosed. The crimping tool includes a base, an operating member and a moving member. The base includes a pivot location, a sliding groove, and first and second fixing locations. The first and second fixing locations are respectively located on two ends of the sliding groove to fix a connector of a wire. The operating member includes a holding portion, a pivot hole and a gear. The pivot hole is pivotally connected to the pivot location of the base through a pivot shaft. The moving member includes a rack, and first and second crimping elements. When the operating member rotates, the gear drives the rack to enable the moving member to move simultaneously, so as to use the first or second crimping element to press fit the connector of the wire placed at the first or second fixing location.
