Terminal Insertion Device Connector Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to stably insert a terminal into a connector cavity while maintaining high positional accuracy, which requires a costly and accurately manufactured fixture, increasing production costs.
Innovation Solution
A terminal insertion device with a holder that includes a push mechanism and positioning portion to accurately position the connector, allowing the terminal to be inserted into the cavity without needing highly accurate holder manufacturing, thus reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixture with high manufacturing accuracy is used to hold the connector, then the terminal can be stably inserted into the cavity with high positional accuracy, but the manufacturing cost of the fixture increases
Solution Approach 1:
The patent introduces a positioning portion as an intermediary component between the holder and the connector. The positioning portion receives and positions the connector at a forward position, allowing the holder to maintain only simple holding functionality while the positioning portion provides the necessary positional accuracy for terminal insertion. This separates the positioning function from the holding function, enabling the holder to be manufactured inexpensively.
2Reliability
If the connector is held firmly by the holder, then the connector is securely positioned, but the holder must be manufactured with high accuracy which increases cost
Solution Approach 1:
The patent divides the connector handling function into two separate components: the holder that provides secure gripping and transport, and the positioning portion that provides precise positioning. The holding recess in the holder securely grasps the connector body, while the positioning portion separately receives and positions the connector at the forward location. This segmentation allows each component to be optimized for its specific function without requiring high manufacturing accuracy for both functions in a single component.

AI summary
An object is to be able to inexpensively manufacture a holder that holds a connector for inserting a terminal. A terminal insertion device inserts a terminal into a cavity formed in a connector. The terminal insertion device includes: a holder in which a holding recess is formed; a push mechanism that pushes the connector held inside the holding recess so as to protrude from the opening; a positioning portion that receives and positions the connector at a position forward of the opening; and a terminal insertion mechanism that inserts the terminal into the cavity of the connector positioned by the positioning portion.
