[0028] Please refer to Figures 1-5 , the present invention provides a technical solution for a waterproof cable joint: a waterproof cable joint, including a female connector 1 and a male plug 2, further including: a waterproof component 4, the waterproof component 4 includes a sealing plate 41, a positioning groove 44 opened at the upper end of the sealing plate 41, a sealing groove 42 opened on one side of the male plug 2, a sealing ring 43 arranged inside the sealing groove 42, a compression groove 45 opened inside the sealing groove 42, a positioning block 46 arranged inside the compression groove 45, a limiting block 47 and a support spring 48.

[0029] Among them, the slot 11 is located in the middle of the female connector 1, and a limiting groove is opened inside the slot 11. The pin 12 is located inside the slot 11, and the number of pins 12 is several groups and is distributed in an array. The plug post 21 and the male plug 2 are of an integral structure. A limiting block is arranged on the outer side of the plug post 21. The pin slot 22 is located in the middle of the plug post 21, and the pin slot 22 is adapted to the pin 12. The number of cables 3 is two groups and is symmetrically distributed. The cables 3 are electrically connected to the pins 12 and the pin slots 22 respectively, so as to facilitate the connection between the female connector 1 and the male plug 2 and conduct the two groups of cables 3.

[0030] In addition, the sealing plate 41 is fixedly connected to the female connector 1. The sealing plate 41 is a hollow cylindrical structure, the sealing groove 42 is an annular structure, the thickness of the sealing groove 42 is less than the thickness of the male plug 2, the sealing plate 41 is adapted to the sealing groove 42, the sealing ring 43 is fixedly connected to the sealing groove 42, the sealing ring 43 is an annular structure, the number of the sealing rings 43 is three and they are distributed in an array, the positioning groove 44 is a cylindrical structure, the number of the positioning grooves 44 is four and they are distributed in an array, the compression groove 45 is adapted to the positioning block 46, the end of the positioning block 46 is a hemispherical structure, the limiting block 47 and the positioning block 46 are an integral structure, both ends of the support spring 48 are connected to the limiting block 47 and the compression groove 45 respectively, and the number of the support springs 48 is equal to the number of the compression grooves 45, which is beneficial to the waterproof sealing between the female connector 1 and the male plug 2, thus protecting the female connector 1 and the male plug 2 from water ingress and improving the safety during the use of the cable 3.

[0031] When connecting the two cables 3, insert the insertion post 21 on one side of the male plug 2 into the insertion slot 11 on one side of the female connector 1, so that the limiting block is connected to the limiting groove, and at the same time, the pin groove 22 is adaptively connected to the pin 12, to conduct the circuit between the two cables 3, and finally perform waterproof sealing through the waterproof component 4.

[0032] It should be noted that through the setting of the waterproof component 4, when sealing between the female connector 1 and the male plug 2, when inserting the insertion post 21 into the inside of the insertion slot 11, it drives the sealing groove 42 to move along the outside of the sealing plate 41 at the same time, so that the three sealing rings 43 respectively squeeze the sealing plate 41. Then the positioning block 46 contacts the end of the sealing plate 41, and the force drives the limiting block 47 to be squeezed along the inside of the compression groove 45, so that the support spring 48 is compressed.
