[0052] Please refer to Figures 1 to 6 As shown, it shows the specific structure of the first preferred embodiment of the present utility model, including a waterproof body 10 and a plug 20.

[0053] The waterproof body 10 includes an outer shell 11 and a sheath 12; the outer shell 11 is made of a rigid material, such as a hard plastic material, of course it can also be other hard materials, without limitation, the outer shell 11 has a receiving cavity 101 with front and rear ends opening and for the plug 31 to pass through from back to front, and a press buckle 111 combined with the device end is integrally formed on the outer peripheral side of the outer shell 11; the sheath 12 is made of an elastic material, such as a silicone material, or other elastic materials, without limitation, the sheath 12 is molded and fixed on the outer shell 11 and seals the outer peripheral side of the outer shell 11, the press buckle 111 exposes the outer surface of the sheath 12 to the outside, and a channel 102 is formed at the rear end of the sheath 12 for the plug 31 to pass through from back to front and tightly fit with the wire 32, and the channel 102 is connected to the receiving cavity 101. In this embodiment, the housing 11 is provided with a snap groove 103, which connects the outside world to the accommodating chamber 101. The push buckle 111 is suspended in the snap groove 103, and the sheath 12 seals and wraps around the snap groove 103, making the push buckle 111 more elastic. Furthermore, the push buckle 111 includes a pressing portion 1111 and a snap portion 1112. The snap portion 1112 is located in front of the pressing portion 1111 and is integrally connected via a connecting rod portion 1113. Both the snap portion 1112 and the pressing portion 1111 are exposed on the outer surface of the sheath 12, while the connecting rod portion 1113 is embedded in the sheath 12. This provides a simple structure, good stability, and easy operation. The outer front surface of the housing 11 is recessed with an annular groove 104. The protective sleeve 12 includes a main body 121 and a sealing ring 122. The sealing ring 122 is molded into the annular groove 104 to ensure a sealed fit with the inner wall of the device's plug-in hole. Furthermore, the annular groove 104 is located in front of and communicates with the snap-fit groove 103. The sealing ring 122 is integrally connected to the main body 121 for greater stability. Furthermore, the rear end of the housing 11 is provided with two transparent blocks 112.

[0054] The plug 20 is removably mounted within the front opening of the accommodating cavity 101. In this embodiment, the front surface of the plug 20 is provided with a forward-facing support arm 201 for securing the plug 31, thereby ensuring a secure installation of the plug 31. Furthermore, the plug 20 is made of a light-guiding material, with light-guiding areas 202 formed on both sides of the front end. The two transparent blocks 112 contact the rear end of the plug 20, allowing light to pass through the plug 20 and reach the transparent blocks 112, where it is then transmitted outward, allowing the user to observe the operating status of the connector. Furthermore, the plug 20 is an inverted U-shaped, integrated structure, offering a simple structure and easy assembly and disassembly.

[0055] The manufacturing and assembly process of this embodiment is described in detail as follows:

[0056] First, the shell 11 is integrally injection molded by injection molding. Then, the shell 11 is placed in a silicone mold to form a sheath 12, so that the sheath 12 and the shell 11 are combined to form an integrated waterproof body 10. Then, the prepared plug 20 is installed from front to back inside the front opening of the accommodating cavity 101.

[0057] During use, the plug 20 is removed from the front opening of the accommodating chamber 101, and then the plug 31 of the plug wire 30 is squeezed into the channel 102 from the back to the front directly or indirectly after putting on a guide cap (not shown in the figure). When squeezed into place, the plug 31 passes through the accommodating chamber 101 and extends forward into the waterproof body 10. Then, the plug 20 is fitted on the rear end of the plug 31 and fixed. Then, the wire 32 is pulled backward to make the plug 31 move backward. The plug 20 moves backward with the plug 31 and is embedded in the front opening of the accommodating chamber 101 and fixed. Due to the limiting effect of the plug 20, the plug 31 cannot continue to move backward, thereby achieving a stable installation of the plug 31. At this time, the front end of the plug 31 protrudes from the front side of the waterproof body 10, and the rear end of the sheath 12 is tightly fitted on the wire 32. Water vapor cannot enter the waterproof body 10 from the rear end of the sheath 12, thereby achieving a waterproof function.

[0058] When the plug 31 is plugged into the socket on the device, the sealing ring 122 on the waterproof body 10 tightly fits against the inner wall of the socket's socket hole to form a seal, preventing moisture from entering the socket hole and achieving waterproofing. At the same time, the snap portion 1112 of the push-button buckle 111 locks with the device's buckle. To remove the plug 31, press the push-button 1111 to release the lock between the snap portion 1112 and the device. Then, pull the waterproof body 10 backward, and the plug 31 can be removed with it.

[0060] In this embodiment, the plug 20 includes a base frame 21 and a connecting block 22. The base frame 21 is U-shaped and is a bent metal part with two fixing legs 211. The connecting block 22 is an injection molded part with fixing holes 221 at both ends. The two fixing legs 211 are inserted into the fixing holes 221 to form a frame-type combined structure, thereby further stabilizing the combination of the plug 20 and the plug 31. Furthermore, the sealing ring 122 is located between the pressing portion 1111 and the snap portion 1112. The surface of the connecting rod portion 1113 is formed with a concave-convex structure 105, which is embedded in the sheath 12, thereby further stabilizing the combination of the sheath 12 and the connecting rod portion 1113.

[0061] The manufacturing and assembly process of this embodiment is basically the same as that of the first preferred embodiment, except that:

[0062] In this embodiment, when assembling the plug 20 to the plug 31 , the base frame 21 and the connecting block 22 are first separated, and then the base frame 21 and the connecting block 22 are fitted over and fixed on the rear end of the plug 31 .

[0063] Please refer to Figures 13 to 18 As shown, it shows the specific structure of the third preferred embodiment of the present utility model. The specific structure of this embodiment is basically the same as the specific structure of the aforementioned first preferred embodiment, except that:
