The socket assembly 2 includes a socket ring shell 21 with a socket inner shell 22 fixedly arranged inside. A partition plate 23 is fixedly arranged on the inner wall of the socket inner shell 22. Inside the partition plate 23, an assembly component 24 is fixedly arranged. The assembly component 24 includes a placement cylinder 241 fixedly arranged inside the partition plate 23. Inside the placement cylinder 241, a connecting rod 242 and a connecting disc 243 are fixedly arranged. A plug disc block 244 is slidably arranged inside the placement 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 end 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. The bottom end of the second frame plate 252 is fixedly arranged with the top end of a backing plate 254. A reserved slot 255 is opened inside the backing plate 254. At the bottom of the ring plate assembly 25, a plate 26 is arranged. At the bottom end of the plate 26, a mounting bracket 27 is fixedly arranged. At the top of the backing plate 254, a socket part 28 is arranged. The socket part 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 plate 26 and inside the mounting bracket 27, a socket conductive core block 29 is fixedly arranged.

[0019] Specifically, the socket connecting piece 282 is assembled and placed on 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.

[0020] Specifically, the inner wall of the reserved slot 255 opened inside the backing plate 254 is fixedly arranged by coating an adhesive with the socket conductive core block 29. Through the above-mentioned method of fixing by injecting glue and bonding, it is convenient to fixedly combine the table block 281 and the socket connecting piece 282.

[0021] Specifically, the table block 281 is placed in fit with the card 253, and the threaded holes opened in the table block 281 and the threaded holes opened 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 board by a milling machine, and then the long board 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.

[0022] Specifically, guide grooves for fitting and sliding with the extension rod 246 are opened inside the front end and the rear end of the placing cylinder 241. When assembling the assembly component 24, the placing cylinder 241, the connecting rod 242, the connecting plate 243, the inserting disc block 244, the second flexible spring 245 and the extension rod 246 are taken as a whole, and the inserting disc block 244 is extruded along the inner wall surface of the placing cylinder 241. At this time, the second flexible spring 245 is extruded. The placing 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 inner through holes of the socket ring shell 21 and the inner through holes of the socket inner shell 22 are sliding limit structures, and the inserting disc block 244 is exposed on the outer wall surface of the socket ring shell 21. The contact surface between the placing 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 inserting disc block 244 extrudes the second flexible spring 245. The inner through holes of the socket ring shell 21 and the inner through holes of the socket inner shell 22 play a role in guiding and sliding limit for the inserting disc block 244.

[0023] 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 slid with the outer guide groove of the socket connecting piece 282 to play an auxiliary positioning role.

[0024] Working process: The disc cover 12, the outer conical cover 15 and the inner conical cover 16 as the outer layer 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.

[0025] 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 cylinder shell 181 made of conductive material. The plug connector 19 is a key plugging structure that conveys 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 cylinder shell 181, so that the trapezoidal plug 184 and the round 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 round 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.

[0026] The table block 281 of the socket component 28 and the socket connector 282 are an integrally glued 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 component 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 component 28.

[0027] 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 fit. The guiding strip arranged on the outer side of the bottom of the plug connector 19 is in an embedded and sliding fit 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.

[0028] 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 in a way of four groups of insertion and combination, which is used to improve the stability of the current transmission and is convenient for the overall replacement of the plug connecting piece 19 and the socket piece 28.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
