[0006] According to the above technical solution, a fixing tooth is provided at the inner bottom of the fixing groove, and embedded tooth holes are evenly opened at the bottom of the rubber block. The fixing teeth are embedded in the corresponding embedded tooth holes. An anti-slip sheet is connected to the outer side of the rubber block, and the anti-slip sheet is embedded in the inner bottom of the fixing groove.

[0007] According to the above technical solution, a fixed arc opening is opened on the outer side of the silicone pad between two adjacent connecting ports, and fixed leather strips are connected between the two ends of the two adjacent outer hoses, and the fixed leather strips are embedded in the adjacent fixed arc openings.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. It is equipped with a pressure-resistant protection component. When the cable is subjected to external pressure, the silicone pad absorbs the external pressure. When the external pressure acts on the outer hose and the rubber block, the outer hose and the buffer channel are compressed to absorb the external pressure again, thereby enhancing the pressure resistance of the cable. At the same time, the elastic ring and the supporting arc sheet are bent in sequence to buffer the external pressure. Under the multiple absorption of the silicone pad, the outer hose and the rubber block and the multiple buffering of the supporting arc sheet, the elastic ring and the supporting arc sheet, the pressure resistance of the cable is further enhanced, and the protection of the outer conductor and the inner conductor is better; At the same time, under the fixing effect of the anti-slip sheet and the fixing teeth on the rubber block, the rubber block can be stably fixed inside the slot. When the outer conductor is subjected to external pressure, under the support of the rubber block, the external force can be prevented from directly acting on the slot, and the slot can be prevented from being deformed, so that the cable can operate normally, and the protection effect of the cable is better. At the same time, the fixed leather strip fixed inside the fixed arc mouth can tighten the silicone pad. When the outer insulation layer of the cable is damaged, the silicone pad can also be tightly wrapped around the outside of the outer conductor, providing better protection for the outer conductor. At the same time, the outer hose is filled with an outer fire extinguishing agent, which can reduce the spread of fire when the cable burns.

[0015] 2. A flame-retardant connection component is provided. When the cable burns, the full carbon aerogel strip will produce carbon dioxide gas when it burns. The carbon dioxide gas is emitted in the PVC wire pipe to dilute the air in the wire pipe and reduce the speed of fire spread. At the same time, the full carbon aerogel strip can absorb external pressure to further increase the compression resistance of the cable. At the same time, the outer layer fire extinguishing agent, the inner layer fire extinguishing agent and the middle layer fire extinguishing agent are all aluminum hydroxide powder. When the fire burns to the outer layer hose, the inner layer hose and the middle layer hose, the aluminum hydroxide powder burns and decomposes to absorb heat and reduce the cable temperature, preventing the fire from spreading. At the same time, the aluminum hydroxide powder burns to produce aluminum oxide that covers the embedded groove, the cross-section groove, the cross-section through hole and the outside of the silicone pad to form a protective layer. The protective layer prevents oxygen from directly contacting the combustible material, further hindering the spread of the fire, leaving more rescue time for the staff and reducing economic losses; When connecting two cables, place the blade inside the cut, and the cut can limit the blade, so that the blade can be prevented from coming out of the cut when cutting, making the cut smoother and preventing the blade from scratching the staff, making it easier to connect the two cables.

[0016] In summary, in the flame-retardant connection assembly, the full carbon aerogel strips and support holes can absorb external pressure, increase the compressive resistance of the cable, and cooperate with the compressive resistance of the compressive protection assembly. When the cable is subjected to external force, the external force is absorbed from the outside to the inside in turn, making the overall compressive resistance of the cable better.

The outer conductor 302 is evenly spaced with slots 303 at the top and bottom. A fixing groove 304 is opened at the position corresponding to the slot 303 on the outer side of the filling protection pad 301. A rubber block 306 is embedded in the fixing groove 304. A fixing tooth 305 is arranged at the bottom of the inner side of the fixing groove 304. The bottom of the rubber block 306 is evenly opened with embedded tooth holes 307. The fixing tooth 305 is embedded in the corresponding embedded tooth hole 307. The outer side of the rubber block 306 is connected with an anti-slip sheet 308, and the anti-slip sheet 308 is embedded in At the bottom of the inner side of the fixing groove 304, the anti-slip sheet 308 is a flexible rubber sheet. When the outer conductor 302 is wrapped, the outer conductor 302 can limit the anti-slip sheet 308. When the cable is subjected to external force, the rubber block 306 is prevented from being separated from the inside of the slot 303. The fixing effect of the fixing teeth 305 on the rubber block 306 can make the fixing effect of the rubber block 306 better. A buffer channel 309 is opened inside the rubber block 306, and an assembly groove 310 is opened on the top of the rubber block 306. The outer side of the outer conductor 302 is wrapped with a silicone pad 314, and the outer sides of the two silicone pads 314 are evenly spaced and provided with connecting openings 315; The top of the rubber block 306 passes through the adjacent slots 303 and the connecting openings 315, an outer hose 311 is embedded in the assembly slot 310, and the outer hose 311 is filled with an outer fire extinguishing agent 312. A fixed arc opening 316 is provided on the outer side of the silicone pad 314 between the two adjacent connecting openings 315, and a fixed leather strip 313 is connected between the two ends of the adjacent outer hoses 311. The fixed leather strip 313 is embedded in the adjacent fixed arc openings 316. The fixed leather strip 313 is made of rubber and has elasticity. Under the connection and tightening action of the fixed leather strip 313, the outer hose 311 can be stably fixed in the assembly slot 310. At the same time, the fixed leather strip 313 is fixed in the fixed arc opening 316 to tighten the silicone pad 314. When the outer insulating layer of the cable is damaged, the silicone pad 314 can also be tightly wrapped around the outer side of the outer conductor 302, so as to provide better protection for the outer conductor 302. The outer side of the silicone pad 314 is evenly spaced with support grooves 317, and a semicircular ring piece 318 is embedded in the support groove 317. The outer side of the semicircular ring piece 318 is evenly welded to one end of the elastic ring 319, and a support arc piece 320 is welded between the other ends of three adjacent elastic rings 319. The outer side of the support arc piece 320 is evenly opened with anti-skid grooves 321. The anti-skid grooves 321 can increase the friction resistance between the support arc piece 320 and the outer insulating layer 411. When the cable is subjected to external force, the outer insulating layer 411 is prevented from rotating easily. The bottom and top of the inner side of the elastic ring 319 are welded with limited The limit block 324 can prevent the elastic ring 319 from being excessively deformed when the elastic ring 319 is deformed by external pressure, so that the elastic ring 319 cannot be restored to its original state. The two ends of the support arc piece 320 at the top are provided with connecting holes 322, and the tops of the two ends of the support arc piece 320 at the bottom are welded with connecting ears 323. The top ends of the connecting ears 323 penetrate the inside of the adjacent connecting holes 322. When the two support arc pieces 320 are connected, the connecting ears 323 are passed through the connecting holes 322 and the connecting ears 323 are bent, so that the two support arc pieces 320 can be quickly connected; A flame retardant connection assembly 4 is arranged outside the inner insulating layer 2, and the flame retardant connection assembly 4 includes an embedding groove 401, an inner layer hose 402, an inner layer fire extinguishing agent 403, a section groove 404, a section through hole 405, a middle layer hose 406, a middle layer fire extinguishing agent 407, a section cut 408, a docking groove 409, a docking strip 410, an outer insulating layer 411, a supporting hole 412, a rubber band 413 and a full carbon aerogel strip 414; Embedding grooves 401 are provided on both sides of the opposite surfaces of the two filling protection pads 301, and an inner layer hose 402 is filled between the two adjacent embedding grooves 401, and the inner layer hose 402 is filled with an inner layer fire extinguishing agent 403. Section grooves 404 are evenly spaced in the middle of the filling protection pad 301, and a section through hole 405 is penetrated at the position corresponding to the section groove 404 on the outer side of the filling protection pad 301. A middle layer hose 406 is placed inside the section groove 404, and the middle layer hose 406 is filled with a middle layer fire extinguishing agent 407. The outer side of the filling protection pad 301 is evenly spaced with cutouts 408, and the cross-sectional shape of the cutout 408 is triangular. When connecting two cables, it is necessary to Use a cutting knife to cut the ends of the two cables, and after cutting, use a connector to fix the ends outside the ends, and use the connector to connect the two cables. When the cutting knife cuts the cable, place the blade inside the cutout 408, and the cutout 408 can limit the blade. When the blade is cutting, it can prevent the blade from coming out of the cutout 408, making the cut smoother and preventing the blade from scratching the staff. The filling protection pad 301 at the bottom is provided with docking grooves 409 on both sides of the top, and the filling protection pad 301 at the top is provided with docking strips 410 on both sides of the bottom, and the docking strips 410 are embedded in the adjacent docking grooves 409, so as to facilitate docking of the two filling protection pads 301; The outer side of the silicone pad 314 and the supporting arc piece 320 is wrapped with an outer insulating layer 411, and support holes 412 are evenly opened inside the outer insulating layer 411. A plurality of support holes 412 are filled with rubber bands 413. The longitudinal cross-section of the support hole 412 is a triangle. The stability of the triangle is utilized to make the supporting strength of the outer insulating layer 411 better. The four support holes 412 are filled with full-carbon aerogel strips 414, and the full-carbon aerogel strips 414 are evenly distributed inside the outer insulating layer 411. When laying the cable, the cable needs to be laid inside the PVC wire pipe. When the cable burns, the full-carbon aerogel strips 414 will produce carbon dioxide gas when burning. The carbon dioxide gas is emitted into the PVC wire pipe to dilute the air in the wire pipe, which can reduce the spread of fire.

[0021] The working principle and use process of the present invention are as follows: when the cable is subjected to external pressure, the triangular support hole 412 performs preliminary buffering on the external pressure. When the external pressure acts on the silicone pad 314, the silicone pad 314 reabsorbs the external pressure. At the same time, the external pressure acts on the outer hose 311 and the rubber block 306. The outer hose 311 and the buffer channel 309 compress and reabsorb the external pressure, further enhancing the pressure resistance of the cable. At the same time, when the external pressure acts on the supporting arc piece 320, the elastic ring 319 and the supporting arc piece 320 bend in sequence to buffer the external pressure. Under the multiple absorption of the silicone pad 314, the outer hose 311 and the rubber block 306 and the multiple buffering of the supporting arc piece 320, the elastic ring 319 and the supporting arc piece 320, when the cable is subjected to external pressure, the protection of the outer conductor 302 and the inner conductor 1 is better. At the same time, under the fixing effect of the anti-slip sheet 308 and the fixing teeth 305 on the rubber block 306, the rubber block 306 can be stably fixed inside the slot 303. When the outer conductor 302 is subjected to external pressure, under the support of the rubber block 306, it can prevent the external force from directly acting on the slot 303, and prevent the slot 303 from being deformed, so that the cable can operate normally, and the protection effect of the cable is better. At the same time, the fixed leather strip 313 is fixed inside the fixed arc 316 to tighten the silicone pad 314. When the outer insulating layer of the cable is damaged, the silicone pad 314 will not become loose. The silicone pad 314 can be tightly wrapped around the outer side of the outer conductor 302, and the protection of the outer conductor 302 is better. At the same time, the outer layer hose 311 is filled with an outer layer fire extinguishing agent 312, which can reduce the spread of the fire when the cable burns. When the cable is bent by external force, the elasticity of the rubber band 413 can prevent the cable from being excessively bent and causing damage to the outer conductor 302. When the external force is removed, the cable can quickly return to its original state by utilizing the elasticity of the rubber band 413, thereby increasing the anti-bending ability of the cable. The full carbon aerogel strips 414 are evenly distributed inside the outer insulating layer 411. When laying the cable, the cable needs to be laid inside the PVC wire tube. When the cable burns, the full carbon aerogel strips 414 will produce carbon dioxide gas when burning. The carbon dioxide gas is emitted into the PVC wire tube to dilute the air in the wire tube, which can reduce the speed of fire spread. At the same time, the full carbon aerogel strips 414 can absorb external pressure and further increase the compression resistance of the cable. At the same time, the outer layer fire extinguishing agent 312, the inner layer fire extinguishing agent 403 and the middle layer fire extinguishing agent 4 07 are all aluminum hydroxide powder. When the fire burns to the outer hose 311, the inner hose 402 and the middle hose 406, the aluminum hydroxide powder burns and decomposes to absorb heat to reduce the cable temperature and prevent the fire from spreading. At the same time, the aluminum hydroxide powder burns to produce aluminum oxide that covers the embedded groove 401, the cross-section groove 404, the cross-section through hole 405 and the outer side of the silicone pad 314 to form a protective layer. The protective layer prevents oxygen from directly contacting the combustibles, further preventing the fire from spreading, leaving more time for the staff to rescue and reducing economic losses. When connecting two cables, it is necessary to use a cutting knife to cut open the breaks of the two cables. After cutting, a connector is fixed to the outside of the break and the two cables are connected using the connector. When cutting the cable with a cutting knife, the blade is placed inside the break cut 408. The break cut 408 can limit the blade, and the blade can be prevented from coming out of the break cut 408 when cutting, making the cut smoother while also preventing the blade from scratching the staff, making it easier to connect the two cables.
