[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, the clamping assembly and the plug connector are of a sliding assembly structure. Among them, the plug conductive core block and the plug connector are both components made of conductive materials. The bottom of the plug conductive core block is fixedly welded to the cylindrical shell made of conductive materials. The plug connector is the key plugging structure for delivering the current of the plug conductive core block and the external power supply cable to the socket assembly. Slide the top column block of the plug connector upward along the inner wall of the cylindrical shell, so that the trapezoidal plug and the circular plate as a whole move outward in the direction of the pull rod, squeeze the first flexible spring until the trapezoidal plug is inserted into the trapezoidal inner groove of the top column block of the plug connector, forming an assembly structure of the clamping assembly and the plug connector.

The socket part and the backing plate can be assembled and fixed by external studs. At this time, the socket connector is placed in an embedded manner with the conductive cylinder of the socket conductive core block to form an insertion structure for conduction. The above-mentioned threaded assembly method also facilitates the overall maintenance and replacement of the socket part, facilitating the guiding assembly for disassembly and repair of the socket conductive connector of the high-voltage connector, and the socket conductive connector located inside the high-voltage connector can be taken out and replaced regularly;

The socket assembly 2 includes a socket ring shell 21 with a socket inner shell 22 fixedly arranged inside. On the inner wall of the socket inner shell 22, a dividing plate 23 is fixedly arranged. Inside the dividing plate 23, an assembling component 24 is fixedly arranged. The assembling component 24 includes a placing cylinder 241 fixedly arranged inside the dividing plate 23. Inside the placing cylinder 241, a connecting rod 242 and a connecting disc 243 are fixedly arranged. A plug disc block 244 is slidably arranged inside the placing cylinder 241. One end face of the connecting disc 243 and one end face of the plug disc block 244 are both fixedly arranged with a second flexible spring 245. At the front and rear ends of the plug disc block 244, extension rods 246 are fixedly arranged. One end of the extension rod 246 is fixedly arranged with a pressing rod 247. At the bottom of the socket ring shell 21, a ring plate assembly 25 is arranged. The ring plate assembly 25 includes a first frame plate 251 fixedly arranged at the bottom of the socket ring shell 21. Inside the first frame plate 251, a second frame plate 252 is fixedly arranged. Inside the second frame plate 252, a card 253 is fixedly arranged. At the bottom of the second frame plate 252, it is fixedly arranged with the top end of a cushion plate 254. A reserved slot 255 is opened inside the cushion plate 254. At the bottom of the ring plate assembly 25, a sheet plate 26 is arranged. At the bottom end of the sheet plate 26, a mounting bracket 27 is fixedly arranged. At the top of the cushion plate 254, a socket piece 28 is arranged. The socket piece 28 includes a table block 281. The inner wall of a slot hole opened inside the table block 281 is fixedly arranged with a socket connecting piece 282 by coating an adhesive. Inside the sheet plate 26 and inside the mounting bracket 27, they are both fixedly arranged with a socket conductive core block 29.

[0042] Specifically, the socket connecting piece 282 is assembled and placed with the inner wall of the reserved slot 255 and the inner wall of the conductive cylinder at the top of the socket conductive core block 29. The socket connecting piece 282 and the socket conductive core block 29 are assembled and combined in the above manner.

[0043] Specifically, the inner wall of the reserved slot 255 formed inside the backing plate 254 is fixedly arranged with the socket conductive core block 29 by coating an adhesive. Through the above-mentioned method of fixing by injecting glue and bonding, it is convenient to combine and fix the table block 281 and the socket connecting piece 282.

[0044] Specifically, the table block 281 is placed in contact with the card 253, and the threaded holes formed in the table block 281 and the threaded holes formed at the top of the backing plate 254 are assembled and fixed by external studs. For the manufacturing process of the table block 281, a threaded through-hole is milled at the center of the whole long plate by a milling machine, and then the long plate is cut along the center line to form two raw material blocks. Finally, the raw material blocks are processed into the table block 281 by a lathe.

[0045] Specifically, guide grooves for fitting and sliding with the extension rod 246 are formed inside the front end and the rear end of the placement cylinder 241. When assembling the assembly component 24, the placement cylinder 241, the connecting rod 242, the connecting disk 243, the plug disk block 244, the second flexible spring 245, and the extension rod 246 are regarded as a whole, and the plug disk block 244 is extruded along the inner wall surface of the placement cylinder 241. At this time, the second flexible spring 245 is extruded. The placement cylinder 241 is placed in the reserved card slot of the dividing plate 23. At this time, under the action of the elastic prestress of the second flexible spring 245 stretching outwards, the through holes inside the socket ring shell 21 and the through holes inside the socket inner shell 22 are sliding limit structures, and the plug disk block 244 is exposed on the outer wall surface of the socket ring shell 21. The contact surface between the placement cylinder 241 and the dividing plate 23 is fixedly arranged by an external spot welding device. The pressing rod 247 is slidably placed inside the socket inner shell 22, and the contact end surfaces of the pressing rod 247 and the extension rod 246 are spot welded and fixed to form the assembly structure of the assembly component 24. Manually press the pressing rod 247, and the plug disk block 244 extrudes the second flexible spring 245. The through holes inside the socket ring shell 21 and the through holes inside the socket inner shell 22 play a role in guiding and sliding limit for the plug disk block 244.

[0046] Specifically, the socket connecting piece 282 is fitted and slidably arranged with the plug connecting piece 19. The guide strip arranged on the outer side of the bottom of the plug connecting piece 19 is fitted and slidably arranged with the outer guide groove of the socket connecting piece 282 to play an auxiliary positioning role.

[0047] Workflow: The disk cover 12, the outer conical cover 15, and the inner conical cover 16, which are the outer layers of the connector, are all made of insulating materials. The plug conductive core block 17 is located at the top of the outer conical cover 15, and a composite insulating sleeve is assembled and fixed on the outer side of the plug conductive core block 17.

[0048] The card-mounted component 18 and the plug connector 19 are of a sliding and assembling structure. Among them, the plug conductive core block 17 and the plug connector 19 are both components made of conductive materials. The bottom of the plug conductive core block 17 is fixedly welded to the cylindrical shell 181 made of conductive material. The plug connector 19 is a key plugging structure for conveying the current of the plug conductive core block 17 and the external power supply cable to the socket component 2. Slide the top column block of the plug connector 19 upward along the inner wall of the cylindrical shell 181, so that the trapezoidal plug 184 and the circular plate 183 as a whole move outward in the direction of the pull rod 186, squeezing the first flexible spring 185 until the trapezoidal plug 184 is inserted into the trapezoidal inner groove of the top column block of the plug connector 19, forming a fixed assembly structure of the card-mounted component 18 and the plug connector 19. When disassembling and replacing the plug connector 19, just manually pull the pull rod 186 outward, which can drive the circular plate 183 and the trapezoidal plug 184 to squeeze the first flexible spring 185. At this time, the trapezoidal plug 184 gradually disengages from the trapezoidal inner groove of the top column block of the plug connector 19 until it loosens and slides off, completing the disassembly of the plug connector 19.

[0049] The table block 281 of the socket part 28 and the socket connector 282 are an integrally glue-coated assembly. When assembling the socket connector 282, place the table block 281 in contact with one end of the support plate fixedly arranged inside the inner wall of the card 253 and the second frame plate 252. Half of the threaded hole is opened on one side of a single table block 281. At this time, the contact end faces of the table blocks 281 placed adjacent to each other form the entire threaded inner hole. The socket part 28 and the backing plate 254 can be assembled and fixed through an external stud. At this time, the socket connector 282 and the conductive cylinder of the socket conductive core block 29 are placed in an embedded manner to form an insertion structure for conduction. The above-mentioned threaded assembly method also facilitates the overall maintenance and replacement of the socket part 28.

[0050] The plug component 1 arranged on the upper side is connected and assembled with the socket component 2 arranged at the bottom. Manually press the pressing rod 247, the plug disc block 244 squeezes the second flexible spring 245, and the guiding piece 14 is placed in an embedded manner with the groove walls opened at the left and right ends of the socket ring shell 21. Then release the pressing rod 247, and the plug disc block 244 slides outward under the action of the elastic prestress of the second flexible spring 245 until the plug disc block 244 is inserted and guided into the through hole opened inside the guiding piece 14. At this time, the socket connector 282 and the plug connector 19 are in an embedded and sliding state. The guiding strip arranged on the outer side of the bottom of the plug connector 19 is in an embedded and sliding state with the outer guiding groove of the socket connector 282 to play an auxiliary positioning role, which is used to ensure the assembly stability of the socket connector 282 and the plug connector 19, and plays a role in facilitating the disassembly and connection and assembly of the plug component 1 and the socket component 2.

[0051] The conductive structure adopted by this device is the plug conductive core block 17, the cylinder shell 181, the plug connecting piece 19, the socket connecting piece 282 and the socket conductive core block 29. Among them, the plug connecting piece 19 and the socket connecting piece 282 are conductively connected by means of four groups of plug-in combinations, which is used to improve the stability of the current transmission and facilitate the overall replacement of the plug connecting piece 19 and the socket piece 28.
