[0002] Wires and cables are essential electrical equipment for transmitting electrical energy and serve as the sole route for the flow of electrical energy. They are widely used in various fields, including petroleum, chemical, metallurgy, power generation, shipbuilding, railways, tunnels, aerospace, construction, mining, housing, hospitals, and schools. These fields place high demands on wires and cables in various performance indicators, such as chemical corrosion resistance, cold and high temperature resistance, excellent insulation properties, good mechanical properties, anti-aging, flexibility, halogen-free and low-smoke flame retardancy, excellent conductivity, energy saving and low consumption, and more importantly, safety and environmental protection.

[0003] Most of the current wires and cables are made of copper cables, but my country's copper resources are very scarce. If aluminum cables are used instead of copper, the conductor wires and cables will have poor performance and low flame retardancy. In addition, when burned by flames in a fire, hydrogen chloride gas and halogen harmful substances will be released. In addition, the existing cables do not reserve a length for cable docking during the connection and fixation process, resulting in the inability to cut off the damaged part and re-dock the cable after the cable connection part is damaged, which affects the normal operation of the cable.

In the accompanying drawings and the following description, known structures and techniques are not shown to avoid causing unnecessary ambiguity to the present invention.

[0021] See also Figures 1 to 6The present invention provides a technical solution: it includes a fire-proof wire assembly and a jacket sealing assembly, the fire-proof wire assembly includes an outer sheath 1, a heat-resistant layer 11, an insulating layer 12, a filling layer 13, a wire body 14 and a bending portion 15, the outer sheath 1 is made of high-temperature resistant rubber, wherein the heat-resistant layer 11 is arranged inside the outer sheath 1, and the insulating layer 12 is inside the heat-resistant layer 11, and the insulating layer 12 is made of insulating rubber, wherein the filling layer 13 is arranged inside the insulating layer 12, and the filling layer 13 can be made of heat-resistant glue, and the wire body 14 is uniformly embedded in the filling layer 13, wherein the wire body 14 is made of copper alloy wire, and the wire body 14 made of copper alloy wire has better fire resistance and high temperature resistance functions, the bending portion 15 is integrally formed and arranged on the outer sheath 1, and the bending portion 15 is formed by bending on the entire wire, and the bending portion 15 belongs to the reserved length of the wire, which is convenient for using the reserved length of the wire when re-fixing the connection part of the wire in the later stage.

[0022] Double-sided clamping frames 1501 are symmetrically placed on both sides of the bending portion 15, one of the double-sided clamping frames 1501 is provided with a docking guide hole 1502 on one side, and a fixedly connected docking plug rod 1503 is arranged on one side of the other double-sided clamping frame 1501, and an adjustment slide groove 1504 is provided through the middle position of the double-sided clamping frame 1501 where the docking plug rod 1503 is arranged, and a lifting support rod 1505 is arranged through one side of the inner side of the adjustment slide groove 1504.

[0023] The two double-sided clamping frames 1501 are connected by snapping, wherein the two upper clamping frames 1501 can put the bending part 15 therein, and the docking rod 1503 can be inserted into the inside of the docking guide hole 1502 to realize the splicing between the two double-sided clamping frames 1501, further facilitating the fixation between the two double-sided clamping frames 1501, and at the same time lifting the support rod 1505 to support the bending part 15.

[0024] The outer side of the lifting support rod 1505 is covered with a cover groove outer plate 1506, and the cover groove outer plate 1506 covers the adjustment slide groove 1504 as a whole. The cover groove outer plate 1506 and the side protrusion 1507 are an integrally formed structure, wherein a fixedly connected side protrusion 1507 is arranged in the middle position of one side of the cover groove outer plate 1506, and a screw-connected locking screw 1508 is arranged through the middle of the side protrusion 1507, and one side of the locking screw 1508 is located inside the spacing hole 1509, and the spacing holes 1509 are evenly opened on one side of the double-sided clamping frame 1501 where the adjustment slide groove 1504 is opened.

[0025] When it is necessary to use the length of the wire reserved for the bending part 15, first loosen the locking screw 1508 so that the locking screw 1508 leaves the current spacing hole 1509, and further slide the cover groove outer plate 1506 and the lifting support rod 1505 downward. As the lifting support rod 1505 slides down, the bending part 15 becomes loose, and then the reserved length of the bending part 15 can be used. Re-tighten the locking screw 1508 so that the locking screw 1508 can be inserted into the inside of another spacing hole 1509.

[0026] The outer sleeve sealing assembly includes a first splicing frame 2, a second splicing frame 21, a bottom extension frame 22, an internal sliding frame 23, an angle rotating rod 24, an inner cavity support rod 25 and an ejection spring 26, wherein the second splicing frame 21 is located on one side of the first splicing frame 2, the bottom extension frame 22 is fixed on the lower side of the first splicing frame 2, wherein the internal sliding frame 23 is arranged inside the bottom extension frame 22, the angle rotating rod 24 is movably connected to the side of the internal sliding frame 23 facing the outside of the bottom extension frame 22, wherein the inner cavity support rod 25 is fixed inside the bottom extension frame 22, and the ejection spring 26 is sleeved on the inner cavity support rod 25.

[0027] The first splicing frame 2 and the second splicing frame 21 can splice and seal the wire connection parts to ensure that the wire connection parts will not be eroded by rainwater and ensure the normal connection of the wires. At the same time, the first splicing frame 2 and the second splicing frame 21 can be quickly opened.

[0028] The first splicing frame 2 and the second splicing frame 21 are respectively arranged on both sides of the outer layer 1, and the first splicing frame 2 and the upper side of the second splicing frame 21 are snap-connected, wherein the bottom extension frame 22 and the first splicing frame 2 are an integrally formed structure, and the angle rotation rod 24 and the second splicing frame 21 are connected by screws.

[0029] The upper snap-fit connection between the first splicing frame 2 and the second splicing frame 21 is quickly opened, and then the ejection spring 26 can push the internal sliding frame 23 outward. Further, when the angle rotation rod 24 leaves the interior of the bottom extension frame 22, the second splicing frame 21 can be rotated. At this time, the wire connection part will be exposed, and the staff can now correct the wire connection part or reconnect it.

[0030] The inner cavity support rod 25 may be a telescopic rod with a telescopic function, so that the other side of the inner cavity support rod 25 can be fixed on the inner sliding frame 23 .

[0031] A contact frame and other structures on the contact frame are arranged on the second splicing frame 21 at a position corresponding to the first splicing frame 2, thereby achieving the function of sealing and fitting one side of the wire.
