[0018] The front and rear ends of the first front shell 3 are open, and the male terminal module 1 is installed in the first front shell 3. The plug-in end of the male terminal module 1 is located in the front end opening of the first front shell 3. The front end opening of the first rear shell 6 is sealed and fixed to the rear end opening of the first front shell 3, and the inner cavities of the two are connected. One end of the cable is inserted into the threading hole 8 of the first rear shell 6 and connected to one end of the connecting terminal at the rear end of the male terminal module 1 in the first front shell 3. Glue is injected through the glue injection hole 7 to fill the inner cavity of the first rear shell 6 and the inner cavity at the rear end of the male terminal module 1 in the first front shell 3. After the glue is cured, the rear end of the male terminal module 1 is waterproof. After the male terminal module 1 and the female terminal module 2 are plugged in, the front part of the first front shell 3 is inserted into the second front shell 9, and the outer wall of the first front shell 3 and the second front shell 9 are tightly sealed by the sealing ring 5 to achieve sealing at the plug-in connection between the male terminal module 1 and the female terminal module 2.

[0019] The front and rear ends of the second front shell 9 are open, and the female terminal module 2 is located in the middle position of the second front shell 9. The insertion space of the first front shell 3 is reserved at the front end of the second front shell 9. The front end opening of the second rear shell 10 is fixed to the rear end opening of the second front shell 9, and the inner cavities of the two are connected. The cable is introduced from the wire entry hole 12 of the second rear shell 10, and is connected to the connecting terminal on the female terminal module 2 at the rear end of the female terminal module 2. Glue is injected through the glue injection port 11 for filling, and the contents of the inner cavity of the second rear shell 10 and the rear end of the female terminal module 2 in the second front shell 9 are filled. After the glue is cured, the rear end of the female terminal module 2 is waterproof.

[0020] This structure adopts a split design, which is convenient for production and assembly. The first rear shell 6 and the second rear shell 10 are added as the connection space between the cable and the terminal, which is convenient for operation. At the same time, they serve as glue injection space and are waterproofed by filling with glue, with good waterproof effect. At the same time, the integrity and strength of the male terminal module 1 and the first waterproof structure, and the female terminal module 2 and the second waterproof structure are improved. They are corrosion-resistant, penetration-proof, and not easy to damage. They are suitable for rainy and snowy weather and high temperature and humid environments.

[0021] The male terminal module 1 in this article is composed of a terminal seat and a terminal. There are multiple terminal mounting holes on the terminal seat. The terminals are installed in the terminal mounting holes, and the terminal seat and the first front shell 3 are an integrated structure. The female terminal module 2 has the same structure as the male terminal module 1. The female terminal module 2 and the second front shell 9 are an integrated structure. The male terminal module 1 and the female terminal module 2 are both existing technologies, and their structures will not be elaborated on.

[0022] like Figure 2 As shown, the first front shell 3 is a cylindrical structure with a rectangular cross section, and the first rear shell 6 is a conical structure with a rectangular cross section.

[0023] The shapes of the first front shell 3 and the first rear shell 6 are limited, which makes it convenient for handheld plugging and more beautiful in appearance.

[0024] like Figure 1 and Figure 3 As shown, a fool-proof slot 13 is provided on the front outer wall of the first front shell 3, and the front end of the fool-proof slot 13 is open, and a fool-proof protrusion 14 corresponding to the fool-proof slot 13 is provided on the inner wall of the second front shell 9. The fool-proof protrusion 14 is located in front of the female terminal module 2, and the front end of the female terminal module 2 is tightly pressed against the rear end of the fool-proof protrusion 14.

[0025] When the first front shell 3 is inserted into the second front shell 9, the anti-foolproof protrusion 14 is inserted into the anti-foolproof slot 13. The anti-foolproof slot 13 and the anti-foolproof protrusion 14 can be used to guide the connection to avoid twisting after being subjected to force after connection, which is more convenient for users to operate. The anti-foolproof protrusion 14 can also play a positioning role for the female terminal module 2.

[0026] like Figure 2-3 As shown, the front end of the first rear shell 6 is inserted into the rear end of the first front shell 3 and the front end of the first rear shell 6 is spaced from the rear end of the male terminal module 1, and the front end of the second rear shell 10 is inserted into the rear end of the second front shell 9 and the front end of the second rear shell 10 is spaced from the rear end of the female terminal module 2.

[0027] This limitation can ensure that the filled glue is in full contact with the inner walls of the first front shell 3, the first rear shell 6, the second front shell 9 and the second rear shell 10. If the first rear shell 6 is pressed against the rear end of the male terminal module 1 in the first front shell 3, and the second rear shell 10 is pressed against the rear end of the female terminal module 2 in the second front shell 9, a gap will be formed, and it will be difficult for the glue to penetrate into and fill the gap, resulting in dead corners and reducing the waterproof effect.

[0028] like Figure 2-3 As shown, it also includes a locking mechanism, which includes a buckle plate 15 provided on the ring block 4, a locking hole 16 provided on the front end of the buckle plate 15, a boss 17 provided on the outer wall of the second front shell 9, and guide platforms 18 provided on both sides of the boss 17. The middle part of the buckle plate 15 is fixed on the outer periphery of the ring block 4, the boss 17 corresponds to the locking hole 16, and the guide platforms 18 are adapted to the width of the buckle plate 15.

[0029] After plugging, the boss 17 is inserted into the card hole 16 of the pinch plate 15. When the cable is subjected to force, the male terminal module 1 and the female terminal module 2 are driven to separate, and the guide platform 18 guides the pinch plate 15.

[0030] like Figure 3 As shown, the boss 17 is in a right-angled trapezoidal structure with the inclined surface facing forward, so that the boss 17 can be more smoothly inserted into the locking hole 16 to reduce resistance.

[0031] like Figure 2-3 As shown, the first rear shell 6 and the second rear shell 10 are respectively provided with a first outer shell 19 and a second outer shell 20, the connection position of the first front shell 3 and the second rear shell 10 is located in the first outer shell 19, and the connection position of the second front shell 9 and the second rear shell 10 is located in the second outer shell 20.

[0032] The first jacket 19 can cover the connection position of the first rear shell 6, the first front shell 3 and the second rear shell 10, the threading hole 8 and the glue injection hole 7. The first jacket 19 and the threading hole 8 have corresponding wire holes with smaller inner diameters reserved at corresponding positions, which play a protective role and further improve the waterproof effect. The second jacket 20 has the same function as the first jacket 19.
