Connector Guide Portion Decouples Current Capacity from Safety

The guide portion acts as an intermediary component between the guide hole and the male terminal. It features a guide hole with a larger diameter than the male terminal, allowing the male terminal to pass through easily, while protruding portions extend into the guide hole to create physical barriers that prevent finger access to the female terminal. This intermediary structure decouples the guide hole diameter from the finger touch prevention function.

The guide portion is segmented into distinct functional regions: the guide hole region with larger diameter for terminal passage, and the protruding portions that extend inward to block finger access. This segmentation allows each region to optimize its specific function - the guide hole accommodates the increased male terminal diameter while the protruding portions maintain safety by preventing finger contact with the female terminal.

The guide portion serves as a mediator that allows the guide hole to be enlarged for higher current capacity while preventing the harmful effect of finger access. The protruding portions within the guide hole create an intermediate barrier that blocks fingers from reaching the female terminal, thus resolving the contradiction between larger guide hole diameter and finger touch prevention.

The solution moves from a two-dimensional consideration (guide hole diameter) to a three-dimensional structure by adding protruding portions that extend radially inward from the guide hole wall. This dimensional addition creates blocking barriers without reducing the guide hole diameter, allowing both large current capacity and finger touch prevention to coexist.
