[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] See Figures 1-3 This embodiment provides a retractable electrical connection mechanism, including:

[0029] Connector 1 for electrical connection with an external electrical connection structure;

[0030] Trigger 2 for electrical connection with external devices;

[0031] An electrical connection housing 3 is used to fix an external device. The electrical connection housing 3 has a power receiving cavity 31 inside. A trigger 2 is disposed in the power receiving cavity 31. A connector 1 is movably disposed on the electrical connection housing 3. One end of the connector 1 is exposed outside the shape of the electrical connection housing 3 as a connection end 11, and the other end of the connector 1 extends into the power receiving cavity 31 to form a trigger end 12. The movement of the connector 1 on the electrical connection housing 3 includes a trigger state in which the trigger end 12 and the trigger 2 abut against each other when connected to an external electrical connection structure, and a power-off state in which the trigger end 12 and the trigger 2 separate when separated from the external electrical connection structure.

[0032] Specifically, there can be multiple connectors 1.

[0033] It is worth noting that the electrical connection mechanism of this application can be a male connector, in which case the external electrical connection structure is a female connector; the electrical connection mechanism of this application can also be a female connector, in which case the external electrical connection structure is a male connector.

[0034] In this embodiment, the electrical connection mechanism further includes a reset elastic body 4 for resetting the connector 1 to a de-energized state when separated from the external electrical connection structure. When the electrical connection mechanism is connected to the external electrical connection structure, the connector 1 will retract on the electrical connection housing under the resistance of the external electrical connection structure. At this time, the reset elastic body 4 will be stretched or compressed, ultimately allowing the external device to be electrically connected to the external electrical connection structure through the connector. When the electrical connection mechanism is disengaged from the external electrical connection structure, the connector 1 extends and resets on the electrical connection housing under the action of the reset elastic body 4, at which time the connector is automatically disconnected from the external device. The inclusion of this reset elastic body makes the electrical connection mechanism more convenient to use.

[0035] In this embodiment, a limiting ring 14 for limiting the position of the connector 1 is fixedly sleeved on the trigger end 12. When the connector 1 extends and resets on the electrical connection housing, the limiting ring 14 can abut against the side wall of the electrical connection cavity 31 to prevent the connector 1 from extending too far or directly detaching.

The provision of the first waterproof ring 54 and the second waterproof ring 55 can further improve the waterproof performance of the connector 1 of the electrical connection mechanism.

[0042] In this embodiment, the electrical connection mechanism further includes an insulating waterproof barrier 6, which is fixedly disposed outside the electrical connection housing 3 and surrounds the outside of the connection end 11.
