DETAILED DESCRIPTION

[0040] like Figure 1-Figure 8 As shown, the cable connector quick docking device in the station house of this embodiment includes a shell 1, a plurality of sockets 11 are provided in pairs at both ends of the shell 1, a plurality of limit plates 3 are provided inside the sockets 11 through a connecting piece 32, and adjacent limit plates 3 are connected by an elastic membrane 31 to form a limit channel;

[0041] A fixing member 5 is hinged between the two limiting channels, and the fixing member 5 includes a first telescopic sleeve 51, a second telescopic sleeve 52 and a slide rail 53. Both ends of the slide rail 53 are fixed to a limiting channel respectively. The first telescopic sleeve 51 and the second telescopic sleeve 52 are fixed to a limiting channel respectively. The first telescopic sleeve 51 and the second telescopic sleeve 52 are slidably matched with the slide rail 53. An insertion rod 54 is fixed to the end of the first telescopic sleeve 51 opposite to the second telescopic sleeve 52, and the second telescopic sleeve 52 is provided with a socket 55 matching the insertion rod 54.

[0042] A telescopic ring 2 is disposed on the outer periphery of the first telescopic sleeve 51 and the second telescopic sleeve 52 . The bottom of the limiting rod 4 penetrates through the shell 1 and is engaged with the top of the telescopic ring 2 .

[0043] The present invention is a disposable device. After the two cables are connected, the shell 1 is fixed to the cables. A limiting channel and a limiting plate 3 with adjustable diameter are provided inside the shell 1. When in use, the cables only need to be pushed inward to complete the docking. The initial position of the telescopic ring 2 is the position with the smallest diameter. If the cable diameter is large, the limiting rod 4 can be pulled up when the cable is initially screwed in to separate the first conical teeth 23 from the second conical teeth 44. At this time, under the action of cable extrusion, the diameter of the telescopic ring 2 and the connecting section of the limiting plate 3 and the telescopic ring 2 expands until the diameter of the telescopic ring 2 reaches a specified size.

[0044] Adjust the diameter of the fixing part 5. When the cable is initially inserted into the limiting channel, due to the large diameter of the cable, the cable will apply an outward thrust to the limiting plate 3. At this time, after the limiting rod 4 is lifted, the limiting plate 3 will expand outward by itself; the first telescopic sleeve 51 and the second telescopic sleeve 52 are respectively hinged to the limiting plate 3 on one side. Therefore, when the diameters of the first telescopic sleeve 51 and the second telescopic sleeve 52 are expanded, the diameter of the end of the limiting channel connected to the first telescopic sleeve 51 and the second telescopic sleeve 52 is also expanded accordingly to better adapt to cables of different diameters.

[0045] Furthermore, the telescopic ring 2 includes a collar 21, an insert ring 22 and a first conical tooth 23. The collar 21 is fixed to the outer periphery of the first telescopic sleeve 51 and the second telescopic sleeve 52. One end of the insert ring 22 is rotatably connected to the collar 21, and the outer wall of the other end of the insert ring 22 is slidably matched with the inner wall of the collar 21; the first conical tooth 23 is fixed to the outer wall of the insert ring 22; the first conical tooth 23 is clamped with the bottom of the limit rod 4; and abutment plates are fixed to the inner peripheries of the opposite ends of the first telescopic sleeve 51 and the second telescopic sleeve 52.

[0046] In the initial state, one end of the plug ring 22 is hinged to the sleeve ring 21, and the other end of the plug ring 22 partially extends into the interior of the sleeve ring 21. The first conical tooth 23 at the top of the plug ring 22 is clamped and fixed to the bottom of the limiting rod 4 to prevent the diameter of the telescopic ring 2 from changing, thereby preventing the diameter of the fixing member 5 from changing; when adjusting the diameter of the fixing member 5, the first conical tooth 23 is separated from the bottom of the limiting rod 4, and the sleeve ring 21 and the plug ring 22 are subjected to tension, causing the plug ring 22 inside the sleeve ring 21 to move outward.

[0047] Furthermore, the bottom of the limiting rod 4 is fixed to the top of the plug 41, a second conical tooth 44 is fixed to the bottom of the plug 41, and the second conical tooth 44 is engaged with the first conical tooth 23; a spring 42 is provided on the outer periphery of the limiting rod 4, and a baffle 43 is fixed to the outer periphery of the limiting rod 4 outside the shell 1; when the second conical tooth 44 is engaged with the first conical tooth 23, the spring 42 is forced to contract.

[0048] The spring 42 is in a stressed and contracted state in the initial state, so as to ensure that the limiting rod 4 and the plug 41 can fix the telescopic ring 2 through the second conical teeth 44 , and the baffle 43 can prevent the limiting rod 4 from completely entering the interior of the housing 1 .

[0049] Furthermore, a torsion spring 33 is fixed inside the limiting plate 3 , and an elastic arm 34 is fixed to the outer end of the torsion spring 33 .

[0050] A torsion spring 33 is arranged behind the elastic arm 34 to provide support therefor. When the cable head is inserted or removed, the torsion spring 33 is automatically compressed or expanded, thereby controlling the clamping or opening of the elastic arm 34 .

[0051] Furthermore, the second telescopic sleeve 52 is filled with electrocoagulation liquid, and a film is fixed on the surface of the socket 55 .

[0052] After the insertion rod 54 is inserted into the insertion hole 55, the electrocoagulant in the second telescopic sleeve 52 flows out to fix the connection between the two cables. The electrocoagulant can enhance the conductivity of the cable connection and make the cable connection more secure and prevent it from loosening.

[0053] Furthermore, the material of the shell 1 is epoxy resin.

[0054] Epoxy resin is an insulating material with excellent insulation performance and waterproof and explosion-proof capabilities. In this embodiment, the voltage rating of the present invention is 20 kilovolts; the length is 400 mm, the width is 200 mm, and the height is 100 mm. The length of the cable shielding part is 150 mm.

[0055] Furthermore, a detection device is arranged inside the shell 1, a display screen is arranged on the top of the shell 1, and the detection device is electrically connected to the display screen.

[0056] The detection device is used to monitor the changes of various data of the present invention and the cable in real time, so as to timely discover and deal with potential safety hazards and enhance the stability and reliability of the power system.

[0057] The method for using the cable connector quick docking device in a station building of this embodiment includes the following steps:

[0058] Adjust the diameter of the telescopic sleeve and the limiting channel according to the diameter of the cable;

[0059] Insert the cable into the limiting channel;

[0060] According to the thickness of the cable sheath, the limiting rod 4 is pulled up until the first conical teeth 23 and the second conical teeth 44 are engaged again;

[0061] If the inner diameter of the telescopic sleeve is smaller than the diameter of the cable core, the limit rod 4 is pulled up again;

[0062] The inner diameter of the telescopic sleeve for completing the diameter adjustment is equal to the diameter of the cable core.

[0063] Insert the two cables until they are connected;

[0064] Push the cable until the end of the cable abuts against the abutment plates on the inner peripheries of the first telescopic sleeve 51 and the second telescopic sleeve 52;

[0065] Continue to push the cable forward, so that the cable drives the first telescopic sleeve 51 and the second telescopic sleeve 52 to approach each other, until the insertion rod 54 enters the insertion hole 55;

[0066] When the electrocoagulation liquid flowing out of the second telescopic sleeve 52 solidifies, the cable connection is completed.

[0067] The cables at both ends are pushed into the shell 1 at the same time, and the middle parts of the two cables enter the first telescopic sleeve 51 and the second telescopic sleeve 52 respectively, and the first telescopic sleeve 51 and the second telescopic sleeve 52 are pushed closer to each other by pushing the abutment plate until the insertion rod 54 enters the insertion hole 55. Since the first telescopic sleeve 51 and the second telescopic sleeve 52 are restricted by the slide rail 53, the first telescopic sleeve 51 and the second telescopic sleeve 52 will not rotate due to the action of the cables, thereby ensuring that the insertion rod 54 enters the insertion hole 55.

[0068] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
