The insulating sleeve 391 is arranged on the side of the plug housing 32 away from the connecting ring 31, and a fourth sealing colloid 392 is fixedly connected inside the insulating sleeve 391. The outer side of the fourth sealing colloid 392 is fixedly connected to the plug housing 32, and a second high-voltage resistant wire 25 is fixedly connected to the side of the fourth sealing colloid 392 close to the insulating sleeve 391. The pin 24 is fixedly connected to the side of the fourth sealing colloid 392 away from the insulating sleeve 391. The side of the fourth sealing colloid 392 away from the insulating sleeve 391 is fixedly connected to the second sealing colloid 23, and the side of the insulating sleeve 391 close to the plug housing 32 is fixedly connected to the fixing rods 393 that are evenly distributed. The outer side of the fixing rod 393 away from the insulating sleeve 391 is fixed It is connected with evenly distributed connecting rods 394, and the connecting rods 394 are fixedly connected with reinforcement rings 395 on the outer sides away from the fixed rods 393. The outer sides of the reinforcement rings 395 are provided with evenly distributed reinforcement grooves 396. The outer sides of the fixed rods 393, the connecting rods 394 and the reinforcement rings 395 are all fixedly connected with the fourth sealing colloid 392. Through this arrangement, the fixing rods 393, the connecting rods 394 and the reinforcement rings 395 can be directly placed in the fourth sealing colloid 392, so that the fixing rods 393, the connecting rods 394 and the reinforcement rings 395 are fixed by the fourth sealing colloid 392, so that the installation of the insulating sleeve 391 is more stable and the insulating sleeve 391 is prevented from falling off the fourth sealing colloid 392. At the same time, the reinforcement grooves 396 can increase the contact area between the reinforcement ring 395 and the fourth sealing colloid 392, so that the adhesion between the reinforcement ring 395 and the fourth sealing colloid 392 is more stable.

[0022] Working process: When producing this circular electrical connector, first, a plurality of socket tubes 181 are passed through the positioning plate 14, and then the socket tubes 181 are inserted into the front mounting shell 13, at which time the positioning plate 14 and the front mounting shell 13 fit each other, and then the positioning plate 14 and the front mounting shell 13 are inserted into the socket housing 11 together, at which time the front mounting shell 13 and the socket housing 11 fit each other, and then one end of the first high-voltage resistant wire 183 is passed through the rubber block 389 and the rear shell 381 and inserted into the socket rod 182, the first high-voltage resistant wire 183 and the socket rod 182 are welded, and then the limiting ring 16 is placed into the socket housing 11, and as the limiting ring 16 moves toward the positioning plate 14 in the socket housing 11, the limiting ring 16 gradually moves to the socket housing 1 1, at this time, the limiting ring 16 is inserted into the limiting groove 15 opened in the socket shell 11 under the action of its own elasticity, so as to limit the positioning plate 14 and the front mounting shell 13, and then the first sealing colloid 17 is poured into the socket shell 11 until the first sealing colloid 17 solidifies, and then the second high-voltage resistant wire 25 is passed through the insulating sleeve 391, and then the pin 24 and the second high-voltage resistant wire 25 are welded, and after welding, the pin 24 is inserted into the plug shell 21, and then the second clamping ring 6 is placed in the second clamping groove 22 opened in the plug shell 21, and then the plug shell 21 and the pin 24 are inserted into the plug shell 32 together, and after the plug shell 21 drives the second clamping ring 6 to move to a suitable position, the second clamping ring 6 is Under the action of its own elasticity, it is inserted into the fourth card slot 37 opened in the plug shell 32 to position the plug shell 21. At this time, an appropriate amount of second sealing colloid 23 is poured into the plug shell 32 until the second sealing colloid 23 solidifies. At this time, a fourth sealing colloid 392 is poured into the plug shell 21 to fit the insulating sleeve 391 on the plug shell 32. At this time, part of the fourth sealing colloid 392 is squeezed between the second high-voltage resistant wire 25 and the insulating sleeve 391 until the fourth sealing colloid 392 solidifies. At this time, the fixing rod 393, the connecting rod 394 and the reinforcement ring 395 arranged in the fourth sealing colloid 392 can limit the insulating sleeve 391 to prevent the insulating sleeve 391 from falling off. At the same time, the outer side of the reinforcement ring 395 The reinforcement groove 396 can increase the contact surface between the reinforcement ring 395 and the fourth sealing colloid 392, so that the reinforcement ring 395 and the fourth sealing colloid 392 are more tightly adhered. Then, the first clamping ring 5 is placed in the first clamping groove 12 provided in the socket housing 11, and the socket housing 11 and the first clamping ring 5 are placed in the connecting ring 31 together. When the first clamping ring 5 moves to the third clamping groove 36 provided in the connecting ring 31, the first clamping ring 5 is clamped into the third clamping groove 36 under the action of its own elasticity, so as to position the socket housing 11. At this time, the rear shell 381 is clamped on the outside of the socket housing 11. When the rear shell 381 moves, the clamping spring 384 is driven to move by the mounting rod 383, so that the clamping spring 384 contacts the spherical end of the connecting rod 394.Until the clamping spring 384 is clamped on the outside of the spherical end of the connecting rod 394, the rear shell 381 is positioned, and then the third sealing colloid 382 is poured through the gap between the rear shell 381 and the first high-voltage resistant wire 183 until the third sealing colloid 382 solidifies, and then the clamping cover 386 is covered on the clamping seat 385, and the bolt 387 is passed through the clamping cover 386 and the nut 388 in the clamping seat 385 is spirally connected to install the clamping cover 386 and the clamping seat 385. At the same time, the clamping cover 386 and the clamping seat 385 clamp the rubber block 389, so that the rubber block 389 is deformed to fix the first high-voltage resistant wire 183. To limit the first high-voltage-resistant conductor 183, the sealant is used to insulate the pins 24 and the socket barrels 181 by direct glue filling, and the pins 24 and the socket barrels 181 can be fixed at the same time. While reducing the weight, the spacing between the multiple pins 24 and the spacing between the multiple socket barrels 181 can also be reduced. Then, the sealing ring 4 is sleeved on the outside of the socket shell 11, and then the plug shell 21 is inserted into the socket shell 11. The positioning rod 34 cooperates with the positioning groove 35 provided by the plug shell 32 to prevent errors. At this time, the pin 24 is inserted into the socket barrel 181, and the conductive spring 185 in the socket barrel 181 contacts the pin 24. After the electrical connection is achieved, the rotating plate 331 is rotated, and the rotating plate 331 drives the nut 332 to rotate. The nut 332 is threadedly connected to the connecting ring 31. As the nut 332 rotates, the rotating plate 331 is gradually driven to move toward the connecting ring 31 until the rotating plate 331 contacts the positioning ball 330. At this time, as the rotating plate 331 rotates, the rotating plate 331 moves on the surface of the positioning ball 330, and the positioning ball 330 rotates outside the rotating wheel 339. The rotating wheel 339 rotates in the mounting plate 338. At the same time, the rotating plate 331 moves toward the connecting ring 31. While driving the positioning ball 330 to rotate, the rotating plate 331 pushes the positioning ball 330 to move. At this time, the positioning ball 330 is rotated. The ball 330 pushes the mounting plate 338 to rotate, and the mounting plate 338 pushes the limit spring 337 to deform, so that the rotation of the rotating plate 331 is more stable. At the same time, the rotating plate 331 pushes the rotating wheel 339, the mounting plate 338, the spring 337, the mounting ring 335 and the fixing ring 333 to move through the positioning ball 330. The fixing ring 333 drives the plug shell 32 and the plug housing 21 to move, so that the plug shell 32 and the sealing ring 4 are closely fitted. In the process of the rotating plate 331 driving the fixing ring 333 to move, the contact between the rotating plate 331 and the fixing ring 333 is reduced, the friction is reduced, and the rotation of the rotating plate 331 is more stable, so as to realize the connection of this circular electrical connector.
