Sliding Terminal Connector for Small-Diameter Wire Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face difficulties in accommodating wires with reduced diameters due to the need to reduce the vertical interval between contact portions, leading to challenges in inserting the core wire into the terminal.
Innovation Solution
The connector design includes a slide portion with a guide portion inclined inward and disposed outward of the pressing portion, allowing for a larger core wire insertion opening and guiding the wire into the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diameter of the wire is reduced, then the connector can accommodate smaller diameter wires, but the vertical interval between the upper and lower contact portions must be reduced, making it difficult to insert the core wire into the terminal
Solution Approach 1:
The guide portion is configured to extend in the front-rear direction rather than only in the vertical direction, creating a three-dimensional insertion path. This allows the core wire to be guided along the longitudinal axis of the terminal while the contact portions maintain their vertical spacing, resolving the conflict between accommodating smaller wires and enabling easy insertion
Solution Approach 2:
The guide portion acts as an intermediary structure between the external environment and the core wire insertion point. It provides a dedicated pathway that facilitates smooth insertion of the core wire into the terminal, mediating between the wire and the contact portions without requiring reduction of the vertical interval between contacts
2Adaptability or versatility
If the size of the slide portion is reduced to accommodate smaller wires, then the connector can handle smaller diameter wires, but the core wire may contact the rear end part of the slide portion, preventing insertion
Solution Approach 1:
The guide portion extends in the front-rear direction to create additional insertion space, preventing the core wire from contacting the rear end part of the slide portion. This dimensional extension allows the terminal to accommodate smaller wires while maintaining sufficient clearance for wire insertion
Solution Approach 2:
The guide portion is positioned to preemptively guide the core wire along the correct insertion path before the wire reaches the rear end part of the slide portion. This preliminary guidance action prevents potential contact and interference, ensuring smooth insertion of smaller diameter wires

AI summary
A connector is to be connected to a first wire including a first core wire and extending in a front-rear direction, and provided with a first terminal to be connected to the first core wire, and a connector housing for accommodating the first terminal, the first wire being inserted into the connector housing. The first terminal includes a first terminal body and a first slide portion slidable in the front-rear direction in a state fit to the first terminal body from outside. The first terminal body includes a sandwiching portion for sandwiching the first core wire. The first slide portion includes a core wire insertion opening, a pressing portion for pressing the sandwiching portion, a guide portion disposed in a rear end part of the first slide portion, and a coupling portion continuously coupling the pressing portion and the guide portion in the front-rear direction.
