Terminal Coupling Portion Reduces Step Height for Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire terminals with crimping portions can rattle when disposed in connectors due to steps formed between terminal components, leading to connection issues.
Innovation Solution
A terminal design featuring a terminal body with a mating connecting portion, a wire connecting portion, and a coupling portion, where the wire connecting portion includes sandwiching portions that extend along the wire's direction, and a shell with a pressurizing portion to secure the sandwiching portion, reducing the step and enhancing connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a terminal is constituted by two components including a terminal body and a slide portion disposed behind the terminal body, then the terminal can be connected to the wire by sandwiching the core, but a step is formed between the two components causing the terminal to rattle when disposed in a connector
Solution Approach 1:
The patent combines the terminal body and slide portion into a single integrated terminal structure. The wire connecting portion is formed as an integral part of the terminal body, eliminating the need for a separate slide portion. This merging of components removes the step that caused rattling while maintaining the sandwiching connection capability.
Solution Approach 2:
The terminal is segmented into functional portions (mating connecting portion, wire connecting portion, coupling portion) within a single integrated structure. The wire connecting portion includes a bottom wall and side walls that form sandwiching portions, allowing the core to be secured without requiring separate components.
2Reliability
If a crimping portion is used to connect the terminal to the wire, then the terminal can be securely connected, but the terminal structure becomes more complex with additional components
Solution Approach 1:
The crimping function is merged into the terminal body itself through the wire connecting portion. The side walls rising from the bottom wall form the crimping structure, eliminating the need for separate crimping tools or additional components while maintaining secure connection reliability.
Solution Approach 2:
The terminal body performs the crimping operation on its own through the integrated wire connecting portion. The sandwiching portions formed by the side walls and bottom wall automatically secure the wire core when the terminal is assembled, without requiring external crimping devices or complex multi-component 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
The design reduces the step in the terminal, preventing rattling and improving connection efficiency by securely sandwiching the wire, thus enhancing the terminal's stability and ease of use in connectors.
Implementation Method 1
the shell includes a pressurizing portion for pressurizing the sandwiching portion toward the wire
Implementation Method 2
the wire connecting portion includes a sandwiching portion extending in an extending direction of the wire, the sandwiching portion sandwiching the wire

AI summary
A terminal is provided with a terminal body including a mating connecting portion, a wire connecting portion and a coupling portion, and a shell. The wire connecting portion includes sandwiching portions extending in an extending direction of a wire and configured to sandwich the wire. The shell includes pressurizing portions for pressurizing the sandwiching portions toward the wire. The mating connecting portion includes a mating bottom wall and mating side walls formed to rise upward in a predetermined rising direction from the mating bottom wall. The wire connecting portion includes a wire-side bottom wall and wire-side side walls rising upward in the rising direction from the wire-side bottom wall. The coupling portion is inclined in a direction opposite to the rising direction from the wire-side bottom wall toward the mating bottom wall to couple the wire-side bottom wall and the mating bottom wall.
