DETAILED DESCRIPTION

[0040] As Figures 1-8 shown, the station building internal cable joint quick butt joint device of the embodiment, including the shell 1, the both ends of the shell 1 are opened with multiple sockets 11, the inner side of the socket 11 is provided with multiple limiting plates 3 through the connecting piece 32, and the adjacent limiting plates 3 are connected to form a limiting channel through the elastic film 31;

[0041] The fixing piece 5 is hinged between the two limiting channels, the fixing piece 5 includes the first telescopic sleeve 51, the second telescopic sleeve 52 and the sliding rail 53, the both ends of the sliding rail 53 are fixed with a limiting channel respectively, the first telescopic sleeve 51 and the second telescopic sleeve 52 are fixed with a limiting channel respectively, and the first telescopic sleeve 51 and the second telescopic sleeve 52 are slidingly matched with the sliding rail 53; the insertion rod 54 is fixed to the opposite end of the first telescopic sleeve 51 and the second telescopic sleeve 52, and the second telescopic sleeve 52 is provided with the insertion hole 55 matched with the insertion rod 54;

[0042] The telescopic ring 2 is arranged on the outer periphery of the first telescopic sleeve 51 and the second telescopic sleeve 52, and the limiting rod 4 is clamped with the top of the telescopic ring 2 after penetrating through the shell 1.

[0043] The present application is a disposable tool, after two cables are connected, the shell 1 is fixed with the cable, the limiting channel and the limiting plate 3 with adjustable diameter are arranged in the shell 1, when used, the butt joint can be completed by only pushing the cable inward, the initial position of the telescopic ring 2 is the position with the smallest diameter, if the cable diameter is larger, the limiting rod 4 can be pulled upward when the cable is initially screwed, so that the first tapered tooth 23 and the second tapered tooth 44 are separated, at this time, under the action of the cable extrusion, the diameter of the telescopic ring 2 and the connecting section of the limiting plate 3 and the telescopic ring 2 is expanded, until the diameter of the telescopic ring 2 reaches the specified size.

[0044] The diameter of the fixing part 5 is adjusted. When the cable is initially inserted into the limiting channel, the cable will exert an outward pushing force on the limiting plate 3 due to the larger diameter of the cable. At this time, after the limiting rod 4 is lifted, the limiting plate 3 will automatically expand outward. 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 diameters of the ends of the limiting channel connected to the first telescopic sleeve 51 and the second telescopic sleeve 52 are also expanded, so as to better adapt to cables with different diameters.

[0045] Further, the telescopic ring 2 comprises a sleeve ring 21, an insertion ring 22, and a first tapered tooth 23. The outer periphery of the first telescopic sleeve 51 and the second telescopic sleeve 52 is fixed with the sleeve ring 21. One end of the insertion ring 22 is rotationally connected to the sleeve ring 21, and the outer wall of the other end of the insertion ring 22 is slidingly matched with the inner wall of the sleeve ring 21. The first tapered tooth 23 is fixed to the outer wall of the insertion ring 22. The first tapered tooth 23 is clamped to the bottom of the limiting rod 4. The inner periphery of the opposite ends of the first telescopic sleeve 51 and the second telescopic sleeve 52 is fixed with an abutting plate.

[0046] In the initial state, one end of the insertion ring 22 is hinged to the sleeve ring 21, and the other end of the insertion ring 22 partially extends into the sleeve ring 21. The first tapered tooth 23 at the top of the insertion ring 22 is clamped and fixed to the bottom of the limiting rod 4, so as to prevent the diameter of the telescopic ring 2 from changing, and further prevent the diameter of the fixing part 5 from changing. When the diameter of the fixing part 5 is adjusted, the first tapered tooth 23 is separated from the bottom of the limiting rod 4. The sleeve ring 21 and the insertion ring 22 are under tension, so that the insertion ring 22 inside the sleeve ring 21 moves outward.

[0047] Further, the bottom of the limiting rod 4 is fixed with a plug 41, and the bottom of the plug 41 is fixed with a second tapered tooth 44. The second tapered tooth 44 is clamped to the first tapered tooth 23. A spring 42 is arranged on the outer periphery of the limiting rod 4. A baffle 43 is fixed to the outer periphery of the limiting rod 4 outside the shell 1. When the second tapered tooth 44 is clamped to the first tapered tooth 23, the spring 42 is under stress and is contracted.

[0048] The spring 42 is under stress and is contracted 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 tapered tooth 44. The baffle 43 can prevent the limiting rod 4 from completely entering the inside of the shell 1.

[0049] Further, a torsional spring 33 is fixed inside the limiting plate 3. An elastic arm 34 is fixed to the outer end of the torsional spring 33.

[0050] The elastic arm 34 is supported by the torsional spring 33 behind it. When the cable head is inserted or pulled out, the torsional spring 33 is automatically compressed or relaxed, thereby controlling the clamping or opening of the elastic arm 34.

[0051] Further, the second telescopic sleeve 52 is filled with an electric coagulation liquid, and a film is fixed to the surface of the insertion hole 55.

[0052] After the insertion rod 54 is inserted into the insertion hole 55, the electrocondensate in the second telescopic sleeve 52 flows out to fix the part connected by the two cables. The electrocondensate can enhance the conductivity of the cable connection part, and make the cable connection part more firm and avoid loosening.

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

[0054] The epoxy resin is an insulating material, which has excellent insulation performance and waterproof and explosion-proof capacity. In this embodiment, the voltage resistance level of the present application is 20 kilovolts; the length is 400 millimeters, the width is 200 millimeters, and the height is 100 millimeters. The length of the cable shielding part is 150 millimeters.

[0055] Further, the shell 1 is provided with a detection device, and the shell 1 is provided with a display screen at the top, and the detection device is electrically connected with the display screen.

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

[0057] The use method of the cable joint quick butt joint device in the station building of this embodiment comprises the following steps:

[0058] According to the diameter of the cable, the diameter of the telescopic sleeve and the limiting channel is adjusted;

[0059] The cable is inserted into the limiting channel;

[0060] According to the thickness of the cable sheath, the limiting rod 4 is pulled until the first tapered tooth 23 and the second tapered tooth 44 are re-coupled;

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

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

[0063] The two cables are inserted until the butt joint is completed;

[0064] The cable is pushed until the end of the cable abuts against the abutting plate in the inner periphery of the first telescopic sleeve 51 and the second telescopic sleeve 52;

[0065] The cable is continuously pushed to drive the first telescopic sleeve 51 and the second telescopic sleeve 52 to approach each other until the insertion rod 54 enters the inside of the insertion hole 55;

[0066] After the electrocondensate in the second telescopic sleeve 52 flows out and solidifies, the butt joint of the cable is completed.

[0067] The two cables at both ends are simultaneously pushed into the inside of the shell 1, the middle parts of the two cables respectively enter the inside of the first telescopic sleeve 51 and the second telescopic sleeve 52, and the first telescopic sleeve 51 and the second telescopic sleeve 52 are pushed to approach each other by pushing the abutting plate until the insertion rod 54 enters the inside of the insertion hole 55, since the first telescopic sleeve 51 and the second telescopic sleeve 52 are limited 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 cable, so as to ensure that the insertion rod 54 enters the inside of the insertion hole 55.

[0068] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
