Cable Terminal Slider Structure to Prevent Assembly Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal configurations are prone to deformation when a force is applied, compromising the secure connection between the terminal and the electric wire.
Innovation Solution
A terminal design featuring a slider that is movable between two positions, with a pressing portion to securely hold the core wire and a support portion to absorb forces, reducing deformation and enhancing connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slider is used to press the holding section toward the electric wire, then the terminal can be assembled and operated, but the slider is deformed by applied forces
Solution Approach 1:
The slider is divided into functionally distinct sections: a pressure receiving portion that accepts assembly forces and a support portion that provides structural reinforcement. This segmentation allows the force application area to be separated from the load-bearing critical sections, enabling easy assembly while preventing deformation in the holding section area.
Solution Approach 2:
The support portion is designed in advance to receive and distribute forces applied to the pressure receiving portion. This preemptive structural arrangement cushions the slider against deformation before forces can affect the holding section, ensuring the slider maintains its shape and function during assembly and operation.
2Strength
If the slider is made more rigid to prevent deformation, then deformation resistance improves, but the ease of assembly and operation deteriorates
Solution Approach 1:
The slider exhibits local quality variations with different thicknesses and structural characteristics at different positions. The support portion has increased thickness and structural reinforcement specifically where forces are applied, while other areas maintain their original design for ease of assembly. This localized strengthening provides deformation resistance exactly where needed without making the entire slider difficult to assemble.

AI summary
A terminal to be coupled to a front end portion of an electric wire. The terminal includes a terminal body and a slider. The terminal body includes a holding section holding a core wire of the electric wire. The slider is movable in a front-rear direction between a first position and a second position that is on a front side with respect to the first position while the slider being fitted on a section of the terminal body including the holding section. The slider includes a pressing portion that presses the holding section toward the electric wire when the slider is at the second position. The slider includes a pressure receiving portion that is pushed from a rear side to move the slider from the first position to the second position. The slider includes a support portion that receives a force applied to the pressure receiving portion that is pushed.
