Description

Technical Field

[0001] The invention belongs to the technical field of wire and cable splicing, in particular to a wire and cable that can be spliced ​​with each other and a wire and cable splicing method. Background Art

[0002] In many construction sites in mountainous areas, cables are often laid at high altitudes. Many cables are installed in the air and there are many of them. Due to the rugged end faces in the mountainous areas, the distance between the two towers cannot be controlled. In addition, what needs to be laid are often high-voltage lines or power cables. Cables may also have additional uninsulated conductors. When splicing cables, an electrical splicing device is required.

[0003] A patent with the announcement number CN 110086134 A discloses a splicing type cable and wire pre-arrangement device using the bidirectional magnetic principle, and its structure includes a cable, a main body, a splicing box, a sealing line, and a temporary hanger. There are four temporary hangers, which are installed at the bottom of the main body by snapping. The middle of both sides of the main body is provided with a cable. The splicing box is a rectangular structure and is installed in the middle of the main body by embedding. The diverter of the present invention forms a drainage after contacting with the wind, and drives the propeller to move, so that the external shaking pin and the internal shaking pin in the outer packaging device form a shaking control for the cable. When welding between the cable wires, multiple thinner cable wires need to be welded and fixed one by one, and the external shaking pin and the internal shaking pin on the surface of the cable wire form a shaking control for the cable wire, and the shaking control will generate a large pulling force on the welding part of the cable wire, which will cause the welding part to break due to the pulling force.

[0004] In the current existing technology, the cable wire is composed of multiple thinner cable wires. When the cable wires are connected and extended, the multiple thinner cable wires need to be welded and fixed one by one to fix the two cable wires. Since the welding strength is far less than the strength of the entire cable wire, and the contact area between the thinner cable wires is relatively small and the overall structure is relatively scattered, when the cable wire falls under its own gravity, the thinner cable wire welding joints will be deformed due to the pulling of the cable wires themselves, which will cause the cable wire welding joints to be torn and broken.

[0005] To this end, the present invention provides a wire and cable that can be spliced ​​with each other and a wire and cable splicing method. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 9 As shown, an embodiment of the present invention is a kind of wire and cable that can be spliced ​​with each other, including a protective cover 11 and a cable ferrule 13 movably sleeved on the inner wall of the protective cover 11, the inner wall of the cable ferrule 13 is detachably installed with an armor layer 12 movably sleeved on the inner wall of the protective cover 11, a pull-out sleeve 135 is movably sleeved on the outer surface of one end of the armor layer 12, and a butt ferrule 131 movably overlapped on the inner wall of the protective cover 11 is movably sleeved on the outer surface of the cable ferrule 13, and a limiting groove 133 is provided on the outer surfaces of the cable ferrule 13 and the butt ferrule 131, and the outer surface of the pull-out sleeve 135 is movably adjusted on the inner wall of the limiting groove 133. An electric motor 132 is fixedly installed on the outer surface of the sleeve 13 and located in the middle position, and a threaded groove 134 that is threaded and movably sleeved on the outer surface of the output end of the electric motor 132 is provided on the outer surface of the docking sleeve 131 and located in the middle position; a docking groove a3 is provided on the top surface of the pull-out sleeve 135, and a semicircular cover plate a4 is swingably connected to the top surface of the pull-out sleeve 135 and located on the inner wall surface of the docking groove a3, and the inner wall surface of the semicircular cover plate a4 is movably overlapped on the outer surface of the armor layer 12, and a soft strip a7 is provided on the inner wall surface of the semicircular cover plate a4, and a cone thorn head a8 that is movably overlapped on the outer surface of the armor layer 12 is fixedly connected on the outer surface of the soft strip a7;

[0040] The inner wall surface of the armor layer 12 is filled with a filling layer 121, the interior of the filling layer 121 is filled with a sheath 123, a thermal conductive strip 122 is arranged inside the filling layer 121 and on the peripheral edge of the sheath 123, the inner wall surface of the sheath 123 is filled with a shielding layer 124, the inner wall surface of the shielding layer 124 is wrapped and filled with an insulating layer 125, and the inner wall surface of the insulating layer 125 is provided with a conductor 126.

[0041] The peeled thinner conductors 126 are sleeved on the inner wall surface of the limiting groove 133, and then the joints of the cable wires are melt-welded by a capacitor welder so that the joints of the cable wires can be fully fixed, and then the electric motor 132 on the outer surface of the cable wire sleeve 13 is rotated so that the output end of the electric motor 132 is rotated inside the threaded groove 134, and then the cable wire sleeve 13 and the docking sleeve 131 at both ends of the electric motor 132 are moved in the same direction, so that the surfaces of the cable wire sleeve 13 and the docking sleeve 131 are attached to each other, and the length of the electric motor 132 is utilized. The strength and hardness of the cable sleeve 13 and the butt sleeve 131 are firmly fixed together, so that the butt joint of the cable sleeve 13 and the butt sleeve 131 and the welding joint of the conductor 126 will not swing too much due to the subsequent push of the armor layer 12 by the external wind force, and then the welding point of the butt joint of the conductor 126 will not be broken due to pulling, which avoids the small contact area between the thinner cable wires and the overall dispersion. Under the falling of the cable wire’s own gravity, the thinner cable wire welding joint will be deformed due to the pulling of the cable wire itself, resulting in tearing and breaking of the cable wire welding joint;

[0042] When the cable sleeve 13 and the docking sleeve 131 move, the pull-out sleeve 135 on the outer surface of the armor layer 12 slides inside the limiting groove 133. At this time, the raised cavity head 136 on the outer surface of the cable sleeve 13 and the docking sleeve 131 presses down the surface of the semicircular cover plate a4, so that the semicircular cover plate a4 overlaps the inner wall of the docking groove a3, so that the surface of the semicircular cover plate a4 fits the outer surface of the armor layer 12. At this time, the conical head a8 on the surface of the soft strip a7 is squeezed on the surface of the armor layer 12, thereby increasing the firmness between the pull-out sleeve 135 and the armor layer 12. At the same time, the clamping and squeezing of the conical head a8 is used to reduce the effect of excessive slipping of the armor layer 12 on the inner wall of the pull-out sleeve 135.

[0043] like Figures 1 to 9As shown, a sealing strip 111 is provided at the bottom edge of the protective cover 11, a bottom cover 112 is movably sleeved on the outer surface of the protective cover 11, a sealing groove 113 movably sleeved on the outer surface of the sealing strip 111 is provided at one side edge of the overlapping bottom cover 112, a height limiting strip 114 movably sleeved on the cable wire sleeve 13 and the outer surface of the armor layer 12 is fixedly connected on the inner side wall surfaces of the protective cover 11 and the overlapping bottom cover 112, a cushioning sealing head 115 movably overlapped on the outer surface of the armor layer 12 is provided on the inner side wall surfaces of both ends of the protective cover 11 and the overlapping bottom cover 112, and a limiting arc plate 116 is fixedly connected on the outer side surfaces of both ends of the protective cover 11 and the overlapping bottom cover 112. A clamping positioning arc strip 117 is movably sleeved on the inner wall surface of the limiting arc plate 116, a limiting ring a1 is fixedly connected to the inner wall surface of the pulling sleeve 135, and an anti-slip strip a2 movably overlapped on the outer surface of the armor layer 12 is fixedly connected on the outer surface of the limiting ring a1, and an upper groove a5 movably overlapped on the outer surface of the armor layer 12 is provided on one side edge of the semicircular cover plate a4, a lower pressure strip a6 is fixedly connected on the inner wall surface of the semicircular cover plate a4, and the outer surface of the soft strip a7 is fixedly connected to the outer surface of the lower pressure strip a6, and a protruding cavity head 136 is provided on the outer surface of the cable wire sleeve 13 and the docking sleeve 131 and at the outer edge position of the limiting groove 133.

[0044] As an embodiment of the present invention, after the armor layer 12 is welded and positioned inside the cable wire sleeve 13, the protective cover 11 and the overlapping bottom cover 112 are wrapped around the outer edge of the cable wire sleeve 13 and the conductor 126, and then the raised sealing head 115 on the inner wall of the protective cover 11 and the overlapping bottom cover 112 is overlapped on the outer surface of the armor layer 12, and the raised sealing head 115 is used to increase the sealing between the armor layer 12, and at this time, the inner wall of the raised sealing head 115 is overlapped on the outer surface of the cable wire sleeve 13, and then the cable wire sleeve 13 is firmly positioned on the inner wall of the protective cover 11 and the overlapping bottom cover 112, so that the conductor 126 will not be affected by the armor layer 12. The pulling and dragging will cause the welding joint of the conductor 126 to break; the cable ferrule 13 is then raised by the height limiting strip 114 on the inner wall of the protective cover 11 and the overlapping bottom cover 112, and then the position of the cable ferrule 13 is limited, and at the same time, the sealing groove 113 and the sealing strip 111 on the edge position of one side of the protective cover 11 and the overlapping bottom cover 112 are used to seal the connection between the protective cover 11 and the overlapping bottom cover 112. Rainwater from the outside of the wall will penetrate into the connection between the protective cover 11 and the overlapping bottom cover 112, and then the protective cover 11 and the overlapping bottom cover 112 are fixed by sliding the positioning arc strip 117 on the inner wall of the limiting arc plate 116.

[0045] Example 2

[0046] like Fig.10 As shown, a method for splicing wires and cables that can be spliced ​​together comprises the following steps:

[0047] S1. Cut the surface of the cable wire joint, and put the cut cable wire head into the inside of the cable wire sleeve to position and fix it;

[0048] S2, fit the two cable ends together, and weld and fix the exposed cable joints;

[0049] S3. Use the pulling and fixing device to centrally position the joints of the cable wires to prevent the cable wires from being pulled due to their own gravity, which may cause the welding joints to break due to pulling;

[0050] S4. A protective sealing device is installed on the surface of the cable wire, and the cable wire is exposed to the outside world, resulting in oxidation of the cable wire.

[0051] Working principle: a plurality of thinner conductors 126 after peeling are sleeved on the inner wall surface of the limiting groove 133, and then the joints of the cable wires are melted and welded by a capacitor welder so that the joints of the cable wires can be fully fixed, and then the electric motor 132 on the outer surface of the cable wire sleeve 13 is rotated so that the output end of the electric motor 132 is rotated inside the threaded groove 134, and then the cable wire sleeve 13 and the docking sleeve 131 at both ends of the electric motor 132 are moved in the same direction, so that the surfaces of the cable wire sleeve 13 and the docking sleeve 131 are attached to each other, and the length and hardness of the electric motor 132 are used to firmly fix the cable wire sleeve 13 and the docking sleeve 131, so that the docking point of the cable wire sleeve 13 and the docking sleeve 131 and the welding point of the conductor 126 will not produce excessive swing due to the subsequent armor layer 12 driven by external wind force, and then the welding point of the conductor 126 will be pulled and caused to break;

[0052] When the cable sleeve 13 and the docking sleeve 131 are moved, the pull-out sleeve 135 on the outer surface of the armor layer 12 slides inside the limiting groove 133. At this time, the convex cavity head 136 on the outer surface of the cable sleeve 13 and the docking sleeve 131 presses down the surface of the semicircular cover plate a4, so that the semicircular cover plate a4 overlaps the inner wall surface of the docking groove a3, so that the surface of the semicircular cover plate a4 fits the outer surface of the armor layer 12. At this time, the cone thorn head a8 on the surface of the soft strip a7 is pressed on the surface of the armor layer 12, thereby increasing the firmness between the pull-out sleeve 135 and the armor layer 12, and at the same time, the clamping and extrusion of the cone thorn head a8 is used to reduce the effect of excessive slippage of the armor layer 12 on the inner wall surface of the pull-out sleeve 135;

[0053] After the armor layer 12 is welded and positioned inside the cable ferrule 13, the protective cover 11 and the overlapping bottom cover 112 are wrapped around the outer edge of the cable ferrule 13 and the conductor 126, and then the raised sealing head 115 on the inner wall of the protective cover 11 and the overlapping bottom cover 112 are overlapped on the outer surface of the armor layer 12. The raised sealing head 115 is used to increase the sealing between the armor layer 12 and the armor layer 12. At this time, the inner wall of the raised sealing head 115 is overlapped on the outer surface of the cable ferrule 13, and the cable ferrule 13 is firmly positioned on the inner wall of the protective cover 11 and the overlapping bottom cover 112, so that the conductor 126 will not be broken at the welding point of the conductor 126 due to the pulling and dragging of the armor layer 12.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
