[0042] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this embodiment, a quick-installation docking device for the outgoing cable of a transformer gas relay is proposed, which includes a gas relay body 22, an external cable 19 and a docking device body 20. An outgoing cable 21 is fixedly connected inside the gas relay body 22;

[0043] The docking device body 20 has a socket 7 and a plug 11. The socket 7 has a plurality of jacks 13 opened at one end. A transfer ring 5 is rotatably connected to the outside of the plug 11. An internal thread groove 15 is opened on one side of the transfer ring 5. The plug 11 has a plurality of pins 14 provided at one end. Each pin 14 is inserted into the plurality of jacks 13. A fixing ring 3 is fixedly installed on the outside of the socket 7. An external thread tube 12 screwed to the internal thread groove 15 is fixedly installed on one side of the fixing ring 3. The transfer ring 5 is threadedly connected to the external thread tube 12 of the fixing ring 3 through the internal thread groove 15;

[0044] A plurality of wiring grooves 8 are opened on the outside of both the socket 7 and the plug 11. A pressing block 9 is rotatably connected to the inside of each wiring groove 8. A first thread groove 10 is opened on the other side of the fixing ring 3. A first thread ring 17 is screwed into the inside of the first thread groove 10. A first insulating housing 2 is fixedly installed on one side of the first thread ring 17. A second thread groove 16 is opened on the other side of the transfer ring 5. A second thread ring 18 is screwed into the inside of the second thread groove 16. A second insulating housing 4 is fixedly installed on one side of the second thread ring 18.

[0045] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The second insulating housing 4 is located outside the plug 11, and the first insulating housing 2 is located outside the socket 7. The first insulating housing 2 and the second insulating housing 4 can respectively protect the socket 7 and the plug 11, prevent the socket 7 and the plug 11 from being damaged, and at the same time, prevent the connected cable from being exposed outside, effectively reducing the risk of electric shock.

[0046] Both the first insulating housing 2 and the second insulating housing 4 are in a truncated conical structure, and both the first insulating housing 2 and the second insulating housing 4 are in contact with the pressing block 9. In this way, when the socket 7 and the plug 11 are respectively inserted into the first insulating housing 2 and the second insulating housing 4, due to the principle of the conical structure, the pressing block 9 will be gradually pressed, so that the cable core between the pressing block 9 and the wiring groove 8 is clamped more firmly, avoiding detachment.

[0047] The first insulating housing 2 and the first thread ring 17 are of an integrally formed structure, and the second insulating housing 4 and the second thread ring 18 are of an integrally formed structure. This effectively improves the connection strength and stability between the first insulating housing 2 and the second insulating housing 4 and the socket 7 and the plug 11, and further makes the combined structure of the docking device more stable, preventing the docking device from being easily opened, thereby reducing the risk of electric shock.

[0048] Copper sheets are fixedly installed on the inner sides of multiple wiring grooves 8. Multiple pins 14 and multiple sockets 13 are electrically connected to the copper sheets. The socket 7 and the plug 11 are connected to each other through conductors such as copper sheets to achieve the flow of current and the transmission of signals. When the multiple pins 14 are inserted into the multiple sockets 13, the cables connected to both ends of the socket 7 and the plug 11 will also be connected.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a first wire bundling ring 23 and a second wire bundling ring 24 are respectively rotatably connected to the opposite backs of the first insulating housing 2 and the second insulating housing 4. A first sealing ring 25 and a second sealing ring 26 are respectively fixedly installed on the inner sides of the first wire bundling ring 23 and the second wire bundling ring 24. The first wire bundling ring 23 and the second wire bundling ring 24 can well bind the cables and play a fixing role, while the first sealing ring 25 and the second sealing ring 26 can effectively prevent objects from entering the interior of the docking connector body 20, ensuring the normal connection of the docking connector body 20 and effectively extending the service life of the docking connector body 20.

[0050] The first wire bundling ring 23 and the second wire bundling ring 24 are made of insulating materials, and the first sealing ring 25 and the second sealing ring 26 are made of rubber materials. Such a setting has the function of blocking electricity, avoiding the current on the cables inside the docking connector body 20 from overflowing through both ends of the docking connector body 20, and effectively reducing the risk of electric shock.

[0051] The multiple wiring grooves 8 on the outer sides of the socket 7 and the plug 11 are evenly distributed along the radial direction of the socket 7 and the plug 11 on the outer sides of the socket 7 and the plug 11. In this way, when the inner cores of the cables are connected to the socket 7 and the plug 11, they are relatively even, facilitating uniform force application and avoiding the inner cores of the cables from being pulled off.

[0052] One end of the socket 7 has a hole platform 27, and multiple sockets 13 are all located on the hole platform 27. One end of the plug 11 is provided with a guide ring 28, and multiple pins 14 are all located inside the guide ring 28. The guide ring 28 is sleeved on the hole platform 27. The connection between the hole platform 27 and the guide ring 28 has a guiding function, which is conducive to ensuring that the multiple pins 14 are quickly inserted into the multiple sockets 13 and improving the connection speed of the rapid installation of the cable.

[0053] The docking connector body 20 has multiple models, and the diameters of the multiple models of docking connector bodies 20 are all different. This is conducive to adapting to cables of different diameters and multiple cores, facilitating the selection of a docking connector body 20 with a corresponding diameter according to the thickness of the cable to be connected and the number of cores, and is conducive to expanding the use range of the docking connector.

[0054] See Figure 1 , Figure 2 ,Figure 3 , Figure 4 , Figure 5 and Figure 6 , in this embodiment, the cable can be fixed to the socket 7 and the plug 11 by means of the pressing block 9 and the wiring groove 8, and is protected by the first insulating housing 2 and the second insulating housing 4, so as to achieve the effects of simple disconnection and connection work, improving work efficiency, and reducing the risk of high-altitude fall. Moreover, the socket 7 and the plug 11 are plugged by the pin 14 and the jack 13, avoiding the risks of accidental touch and accidental wiring. Repeated disconnection and connection will not wear the outgoing cable 21, and there will be no problems such as power circuit short circuit and grounding risks.

[0055] In this embodiment, the first insulating housing 2 and the second insulating housing 4 are respectively rotatably connected with a first wire bundling ring 23 and a second wire bundling ring 24 at one end. During assembly, the rotation of the first insulating housing 2 and the second insulating housing 4 will not cause friction between the first wire bundling ring 23 and the second wire bundling ring 24 and the cable, ensuring the smoothness of assembly. At the same time, a first sealing ring 25 and a second sealing ring 26 are installed inside the first wire bundling ring 23 and the second wire bundling ring 24, playing a role in waterproofing and oil-proofing.

[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the working principle of the above-mentioned quick-installation docking device for the outgoing cable of the transformer gas relay: a copper sheet is arranged inside the wiring groove 8, which is in contact with the pin 14 and is connected to the jack 13, so that when the pin 14 is inserted into the jack 13, it can be electrically connected to the copper sheet on the socket 7. During assembly, first insert the external cable 19 into the first wire bundling ring 23, the first insulating housing 2 and the first sealing ring 25, and fix it inside the socket 7 by means of the wiring groove 8 and the pressing block 9. Then, screw the first insulating housing 2 and the socket 7 together by means of the first thread ring 17 and the first thread groove 10. After that, pass the outgoing cable 21 of the gas relay through the second wire bundling ring 24, the second insulating housing 4 and the second sealing ring 26, and fix it inside the plug 11 by means of the wiring groove 8 and the pressing block 9. Then, plug the socket 7 and the plug 11 together by means of the jack 13 and the pin 14 to electrically connect the two cables. Finally, screw and fix the adapter ring 5 and the fixing ring 3 together by means of the external thread tube 12 and the internal thread groove 15.

[0057] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
