[0023] Please refer to Figures 1 to 4 , the present invention provides an electrical connector with good waterproof performance, including: a plug housing 1, a socket housing 2 and a plug body 9. It is characterized in that a socket housing 2 is arranged on the side of the plug housing 1, a plug body 9 is arranged inside the plug housing 1, and a power-off structure 19 is arranged on the side of the socket housing 2;

[0024] The power-off structure 19 includes a wiring board 16, a support plate 17 and a support spring 14. A support spring 14 is arranged on the side of the socket housing 2, a support plate 17 is arranged on the side of the support spring 14, and a wiring board 16 is arranged on the side of the support plate 17;

[0025] In this embodiment, when the device has been used for a certain number of years, the sealing ring 10 will show wear or aging, resulting in a gap between the sealing ring 10 and the plug housing 1, thus causing water ingress. At this time, the power-off structure 19 will cause the pressure generated by the water entering the inside of the plug housing 1 to squeeze the wiring board 16 in the jack board 18, causing the wiring board 16 to move in the direction of the support spring 14, driving the sliding block 12 to slide inside the jack board 18, and squeezing the support spring 14 through the support plate 17 under the action of pressure. At this time, the plug body 9 and the slot 11 will be separated, so that the power-off structure 19 plays the role of cutting off the power of the electrical connector.

[0026] Furthermore, a first terminal 3 is provided on the side of the socket housing 2, and a second terminal 13 is provided on the side of the plug housing 1;

[0027] Furthermore, a jack board 18 is provided on the side of the socket housing 2, a sliding block 12 is provided on the side of the wiring board 16, the sliding block 12 is slidably connected to the jack board 18, and a slot 11 is formed on the surface of the wiring board 16;

[0028] In this embodiment, when the slot 11 contacts the plug body 9, the electrical connector will be powered on. When the slot 11 is separated from the plug body 9, the electrical connector will be powered off. When water continuously enters the electrical connector due to the damage of the sealing ring 10 inside the electrical connector, the pressure of the water will squeeze the wiring board 16, causing it to drive the sliding block 12 to move inward to the jack board 18, and the slot 11 and the plug body 9 will be separated, so that the electrical connector will be powered off, avoiding the danger of electric shock and the fire caused by short circuit.

[0029] Furthermore, a sealing ring 10 is provided inside the plug housing 1, a first connecting block 4 is provided on the side of the socket housing 2, and a second connecting block 5 is provided on the side of the plug housing 1;

[0030] In this embodiment, the sealing ring 10 effectively increases the airtightness between the plug body 9 and the slot 11, improves the waterproof performance of the electrical connector, and prevents external moisture from entering the inside of the electrical connector, causing danger. The first connecting block 4 on the socket housing 2 carries a male buckle 7, and there is a female buckle 8 inside the second connecting block 5 of the plug housing 1. When the male buckle 7 enters the second connecting block 5, it will slide inward to form a buckle with the female buckle 8, so that the plug housing 1 and the socket housing 2 are firmly fixed together, increasing the sealing performance between the plug housing 1 and the socket housing 2.

[0031] Furthermore, a button 6 is provided on the side of the second connecting block 5, the button 6 penetrates through the second connecting block 5, and a return spring 15 is provided inside the second connecting block 5;

[0032] Further, a male buckle 7 is provided on the side surface of the first connecting block 4, and a female buckle 8 is provided inside the second connecting block 5. The second connecting block 5 is slidably connected to the female buckle 8;

[0033] In this embodiment, when the plug housing 1 is connected to the socket housing 2, the first connecting block 4 on the socket housing 2 carries the male buckle 7 and aligns it with the opening of the second connecting block 5, allowing the male buckle 7 to slide inside the second connecting block 5. At this time, the jack plate 18 will move towards the inside of the plug housing 1, and the slot 11 will also move towards the inside of the plug housing 1. When the male buckle 7 enters the second connecting block 5, it will slide inward to form a snap with the female buckle 8. The jack plate 18 will closely adhere to the sealing ring 10, and the plug body 9 will be inserted into the slot 11, so that the plug housing 1 and the socket housing 2 are fitted together to energize the electrical connector. When the electrical connector needs to be de-energized, press the button 6 to squeeze the female buckle 8 in the direction of the return spring 15. At this time, the female buckle 8 will be separated from the male buckle 7, and then pull the socket housing 2 to withdraw the male buckle 7 from the second connecting block 5, so that the plug housing 1 and the socket housing 2 are separated, and the plug body 9 is withdrawn from the slot 11, thereby achieving the purpose of disconnecting the electrical connector and achieving the effect of quick installation and disassembly.

[0034] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
