High-Voltage Connector Pre-Lock via Elastic Finger-Touch Prevention

The patent combines the finger-touch prevention portion and the pre-lock structure into a single integrated component. The opening of the finger-touch prevention portion serves dual purposes: preventing finger contact with terminals and providing the pre-lock mechanism through interaction with the recess in the male terminal. This merging eliminates the need for separate pre-lock structures, achieving the pre-lock function without increasing connector size.

The finger-touch prevention portion is designed to perform multiple functions simultaneously. It not only prevents operator fingers from touching the terminals but also provides the pre-lock function through its opening structure that interacts with the male terminal's recess. This multi-functionality allows a single component to replace what would traditionally require separate dedicated structures.

The recess is pre-formed in the male terminal at a position before the male terminal contacts the female terminal. This preliminary structure allows the opening of the finger-touch prevention portion to naturally engage with it during the connector fitting process, automatically creating the pre-lock condition before final terminal contact. The preliminary action is built into the geometry of the components themselves.

The connector components are designed to automatically perform the pre-lock function through their own geometric features without requiring external locking mechanisms or additional操作步骤. The opening and recess structures self-engage during insertion, and the elastic member's biasing force automatically maintains the pre-lock condition, eliminating the need for separate locking operations.
