[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides an embodiment of a high-temperature resistant reinforced radio frequency coaxial cable, comprising a polyethylene sheath 1, a conductor 3, and a sheath 5. The polyethylene sheath 1 has a central hole 2 inside, and the conductor 3 is installed inside the central hole 2. A shielding layer 4 is installed on the outside of the polyethylene sheath 1, and the sheath 5 is installed on the outside of the shielding layer 4. A flame-retardant reinforcement component is provided on the inner wall of the sheath 5. The flame-retardant reinforcement component includes an inner cavity 6, a first wire 7, a second wire 8, and flame-retardant tape 9. The inner wall of the sheath 5 has an inner cavity 6, and the inner cavity 6 has a first wire 7 inside. The front end of the first wire 7 is provided with a second wire 8. Several first wires 7 and second wires 8 are provided inside the inner cavity 6, and the several first wires 7 and second wires 8 are distributed in a cross pattern. The outer walls of the first wires 7 and second wires 8 are fixed with flame-retardant tape 9.
[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, an inner cavity 6 is provided between the shielding layer 4 and the sheath 5. The first thread 7 and the second thread 8 are woven into a mesh and wrapped around the outside of the shielding layer 4 to help increase the toughness during use. The flame-retardant tape 9 is directly wrapped around the outside of the first thread 7 and the second thread 8 to help shape the whole and provide flame-retardant and high-temperature resistance to the inside.
[0025] A vent 10 is provided through the right side of the sheath 5. Several vents 10 are provided through the right side of the sheath 5 and are arranged in a ring. A slot 11 is provided on the outer wall of the sheath 5. The bottom end of the slot 11 extends into the interior of the vent 10. Several slots 11 are provided on the outer wall of the sheath 5 and are arranged at equal intervals. A heat sink 12 is inserted into the interior of the slot 11. A positioning boss 13 is fixed on the outer wall of the heat sink 12.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, during use, the vent 10 is located inside the sheath 5. At the same time, multiple heat sinks 12 are inserted into the inside of the vent 10 through the slots 11 to help dissipate the internal heat and dissipate it to the outside for heat dissipation.
[0027] A shaping tube 14 is provided on the left side of the sheath 5. A connecting tube 15 is fixed on the left side of the shaping tube 14. A clamp 16 is fixed on the right side of the shaping tube 14. A locking cap 17 is provided on the outer side of the shaping tube 14 and the clamp 16. An external thread is provided on the surface of the shaping tube 14. An internal thread is provided inside the locking cap 17. A ramp 18 is fixed on the inner side wall of the locking cap 17. A slide groove 19 is provided on the right side of the locking cap 17.
[0028] Specifically, such as Figure 1 As shown, during use, when the shaping tube 14 is fitted onto the end of the sheath 5, multiple sets of clamps 16 follow the shaping tube 14 onto the end. When the locking cap 17 is rotated and the locking cap 17 moves to the left with the help of the thread, the inclined platform 18 on the inner side can push the multiple sets of clamps 16 to clamp inward. After clamping at the end of the sheath 5, the installation operation of the shaping tube 14 can be completed. The shaping tube 14, clamps 16 and locking cap 17 cooperate to complete the shaping and reinforcement of the end of the sheath 5.
[0029] Working principle: During use, the clamp 16, along with the shaping tube 14, is fitted onto the end of the sheath 5. Rotating the locking cap 17 locks the clamp 16 at the end for fixation. This cooperation reinforces the end of the sheath 5, preventing cracking and ensuring usability. Multiple heat sinks 12 are inserted into the internal vents 10 through slots 11 on the surface of the sheath 5. As heat is transferred from the inside to the outside, the multiple heat sinks 12 work together to accelerate heat transfer and enhance overall heat dissipation. Simultaneously, an inner cavity 6 is provided between the shielding layer 4 and the sheath 5. The first thread 7 and the second thread 8 are woven into a mesh and fitted onto the outside of the shielding layer 4 to increase its toughness during use. Flame-retardant tape 9 is directly wrapped around the outside of the first thread 7 and the second thread 8, assisting in overall shaping while providing flame-retardant and high-temperature resistance to the inside.
