[0024] Embodiment 1

[0025] An electromagnetic shielding cable with multiple protections, as Figures 1 - 4 shown, includes a protective shell 1, an insulating protective layer 2, and a support protection cylinder 8 installed inside the protective shell 1. A flame-retardant support port 9 is provided on one side of the support protection cylinder 8. There are at least four flame-retardant support ports 9. A number of support shells 12 are installed on the inner wall of the flame-retardant support port 9, and the number of support shells 12 is vertically distributed. A placement protection chamber 10 is installed at the upper end of the support shell 12, and an auxiliary chamber 14 is installed at the lower end of the support shell 12. Limit protection semi-rings 15 are installed at both the upper and lower ends of the support shell 12. When the device is operating, the flame-retardant support port 9 places a number of support shells 12 under the support of the support protection cylinder 8. Under the guidance of the flame-retardant support port 9, flame-retardant particles are poured into the inside of the support shell 12. By arranging the multiple support shells 12 vertically, the poured flame-retardant particles can flow into the inside of the lower support shell 12 in a timely manner. At the same time, through the placement protection chamber 10 and the auxiliary chamber 14 provided on both sides of the support shell 12, when the device moves or is used in different directions as a whole, the movement of the flame-retardant particles can be restricted, so as to ensure that at least one side of the placement protection chamber 10 and the limit block 13 can store and place the flame-retardant particles. Through the limit protection semi-rings 15 provided at both the upper and lower ends of the support shell 12, a certain blocking effect can be exerted on the placement protection chamber 10 and the auxiliary chamber 14 to restrict the movement of the flame-retardant particles. Through the placement of the flame-retardant particles by the support shell 12, it is ensured that when the device catches fire spontaneously, it can be stopped in time. At the same time, through the formation of a first protection mechanism from the outside of the protective shell 1, a second protection mechanism is formed from the inside by the support protection cylinder 8, and the support shell 12 and the limit protection semi-ring 15 are combined to form a third protection mechanism, so that the device has a multi-layer protection effect and ensures the safety and stability during its use.

[0026] An electromagnetic shielding cable with multiple protections, as Figures 1 - 4As shown, a heat insulation protection layer 4 is fixedly connected to the outside of the insulation protection layer 2. The heat insulation protection layer 4 is used for heat insulation of the insulation protection layer 2. A buffer protection layer 5 is arranged on the outside of the heat insulation protection layer 4. The buffer protection layer 5 is simultaneously arranged on the outside of a plurality of heat insulation protection layers 4. By winding the buffer protection layer 5 around the outside of the heat insulation protection layer 4, the buffer protection layer 5 is simultaneously wound and fixed to a plurality of heat insulation protection layers 4, so that the heat insulation protection layer 4 connects and fastens the insulation protection layer 2, improves the heat insulation effect of the heat insulation protection layer 4 on the insulation protection layer 2, and at the same time plays a protective role, thereby isolating the positions between each insulation protection layer 2 to prevent the temperature from rising too fast due to too close contact. By winding the buffer protection layer 5 in multiple layers, a certain buffering effect can be provided for the heat insulation protection layer 4 and its internal components, playing the role of heat insulation protection and buffer protection.

[0027] As Figures 1 - 4 shown, a middle ventilation pipe 6 is inserted into the middle of the support protection cylinder 8. A plurality of ventilation openings 7 are opened on one side of the middle ventilation pipe 6. Through the middle ventilation pipe 6 arranged in the middle of the device and the ventilation openings 7 opened in the middle of the middle ventilation pipe 6, ventilation and heat dissipation can be carried out from the middle of the device, thereby ensuring the temperature of the components outside the middle ventilation pipe 6 and achieving the effect of dissipating heat from multiple angles for the overall device.

[0028] Embodiment 2

[0029] As Figures 1 - 4 shown, a limiting block 13 is fixedly connected to one side of the limiting protection semi-ring 15. There are a plurality of limiting blocks 13. A plurality of circulation openings 11 are opened on both corresponding sides of the support housing 12. When the inside of the uppermost support housing 12 is full, the flame retardant particles inside it will flow to the outside of the support housing 12 through the circulation of the circulation openings 11. Then, by tilting the whole device, the flame retardant particles will flow to the lower support housing 12, so as to place the flame retardant particles at various parts of the cable. At the same time, under the limitation of a plurality of auxiliary chambers 14 inside the multiple support housings 12, the flow of the flame retardant particles is restricted, thereby ensuring that there are flame retardant particles placed inside each support housing 12, further improving the protection effect of the support housing 12 on the device and enhancing its protection performance.

[0030] As Figures 1 - 4 shown, a wire core 3 is arranged on one side of the support protection cylinder 8. There are a plurality of wire cores 3. An insulation protection layer 2 is fixedly connected to the outside of the wire core 3. By winding a plurality of wire cores 3 under the insulation protection of the insulation protection layer 2, a plurality of insulation protection layers 2 cross each other, improving the stability of the insulation protection layer 2 in enhancing the protection effect.

[0031] Working principle: The flame-retardant support port 9 places multiple support housings 12 under the support of the support protection cylinder 8. Under the guidance of the flame-retardant support port 9, flame-retardant particles are poured into the interior of the support housings 12. By arranging the multiple support housings 12 vertically, the poured flame-retardant particles can flow into the interior of the lower support housings 12 in a timely manner. At the same time, through the placement protection chambers 10 and auxiliary chambers 14 opened on both sides of the support housings 12, when the device as a whole moves or is used in different directions, the movement of the flame-retardant particles can be restricted, so as to ensure that at least one side of the placement protection chamber 10 and the limit block 13 can store and place the flame-retardant particles. Through the limit protection semi-rings 15 arranged at the upper and lower ends of the support housings 12, a certain blocking effect can be exerted on the placement protection chambers 10 and the auxiliary chambers 14 to restrict the movement of the flame-retardant particles. By placing the flame-retardant particles in the support housings 12, it is ensured that when the device catches fire spontaneously, it can be stopped in time to prevent the further spread of the fire. At the same time, through the formation of the first protection mechanism from the outside of the protection housing 1, the second protection mechanism from the inside of the support protection cylinder 8, and the combination of the support housing 12 and the limit protection semi-ring 15 to form the third protection mechanism, the device has a multi-layer protection effect, ensuring the safety and stability during its use.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
