The first stop-pull mechanism 21 and the second stop-pull mechanism 22 are respectively provided in the first fixed-point rotation structure and the second fixed-point rotation structure to achieve fixed-point rotation and prevent the electrical connection mechanism from being connected to the ground.
[0019] Specifically, by moving the pull-out handle 23, the first stop pull-out mechanism 21 and the second stop pull-out mechanism 22 are simultaneously driven to rotate at a fixed point. The male charging head is separated and pulled out by rotational dissociation, saving pulling force and process, and making the operation simple and convenient. The electrical connection isolation structure effectively separates the terminals, making it difficult for the terminals to have cross-current. Furthermore, the innovative design of the first and second fixed-point rotation structures prevents the first and second stop pull-out mechanisms 21 and 22 from interfering with the normal power supply of the electrical connection mechanism due to damage to the lifting end 2, preventing leakage and cross-current safety hazards.

[0024] Preferably, the first stop-pull mechanism 21 includes an integrally formed detachment part, a connecting part, and a rotation limiting part. The rotation limiting part extends and is provided with a rotation limiting protrusion 24.

The connecting part passes through the limiting hole; The detachment part has a detachment protrusion extending from one end away from the pull-out handle 23.

[0028] This utility model features a reasonable and ingenious design. By tossing the pull-out handle, it synchronously drives the first and second stop-pull-out mechanisms to rotate at a fixed point, achieving the separation and removal of the male charging head connector through rotational dissociation. This saves on pulling force and process, making operation simple and convenient. The electrical connection isolation structure effectively separates the terminals, making it less likely for cross-current to occur between them. Furthermore, the innovative design of the first and second fixed-point rotation structures prevents the first and second stop-pull-out mechanisms from interfering with the normal power supply of the electrical connection mechanism due to damage to the pull-out end, thus preventing leakage and cross-current safety hazards. It overcomes the safety hazard caused by the handle piercing the internal terminals due to damage in existing male connector structures, optimizing service life and charging safety.
