The outer surface of the protective sleeve is provided with the inner support sleeve, the outer surface of the inner support sleeve is fixedly provided with the support column, the other end of the support column is fixedly provided with the outer support sleeve, and the outer support sleeve is bonded to the rubber sleeve. Multiple sets of heat dissipation fins are fixedly provided on the outer surface of the inner support sleeve.

[0007] As a preferred embodiment of the present invention, the closing mechanism includes a mounting frame, a movable rod, a return spring, and a rubber plug. The mounting frame is fixedly connected to a rubber sleeve. The movable rod is slidably connected inside the mounting frame. A return spring is sleeved on the outer surface of the movable rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) By setting a closing mechanism, the rubber plug is pushed down, causing the return spring to undergo elastic deformation. At the same time, when the rubber plug moves, it can drive the movable rod to move down. At this time, the cold air pipe head is inserted into the through hole groove, and the cold air can be injected into the rubber jacket, thereby improving the physical cooling effect of the cable. When the cold air pipe head is separated from the through hole groove, the rubber plug can be moved under the push of the elastic deformation of the return spring, so that the rubber plug and the through hole groove are engaged and connected. In this way, the cold air inside the rubber jacket can be kept inside, thereby improving the cooling effect of the cable. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 This invention provides a technical solution for a flexible high-temperature resistant cable for outdoor charging piles: It includes a protective jacket 1, an inner heat insulation mechanism on the inner side of the protective jacket 1, a protective inner sleeve 16 on the inner side of the inner heat insulation mechanism, a flame-retardant filler 17 on the inner side of the protective inner sleeve 16, multiple sets of cable cores 18 inside the flame-retardant filler 17, multiple sets of support mechanisms on the outer surface of the protective jacket 1, a rubber jacket 6 on the outer surface of the support mechanisms, a through-hole groove 8 inside the rubber jacket 6, and a closing mechanism on the inner side of the rubber jacket 6 for opening and closing the through-hole groove 8. Through this design, the support mechanism supports the gap between the rubber jacket 6 and the protective jacket 1, ensuring that cold air is injected into the inner cavity of the rubber jacket 6. Simultaneously, the closing mechanism closes the through-hole groove 8, keeping the cold air inside the rubber jacket 6 for cooling the cable. Furthermore, the inner heat insulation mechanism isolates the heat generated by the cable cores and the heat from the outside of the cable, thus protecting the overall service life of the cable.

[0018] In other embodiments, the inner insulation mechanism includes a composite silicate layer 13, an aerogel felt layer 14, and a mica insulating tape 15. The outer surface of the composite silicate layer 13 is bonded to the inner side of the protective jacket 1, the aerogel felt layer 14 is bonded to the inner side of the composite silicate layer 13, the mica insulating tape 15 is bonded to the inner side of the aerogel felt layer 14, and the inner side of the mica insulating tape 15 is bonded to the outer side of the protective inner sleeve 16. By setting the composite silicate layer 13, the aerogel felt layer 14, and the mica insulating tape 15, the heat insulation effect between the protective jacket 1 and the protective inner sleeve 16 can be enhanced, thereby improving the overall high-temperature resistance of the cable. Under the action of the inner insulation mechanism, the heat generated by the cable core can be isolated, and the heat outside the cable can also be isolated, thus protecting the overall service life of the cable.

[0019] In other embodiments, the support mechanism includes an inner support sleeve 2, an outer support sleeve 3, a support column 4, and heat dissipation fins 5. The outer surface of the protective sleeve 1 is provided with the inner support sleeve 2, the outer surface of the inner support sleeve 2 is fixedly provided with the support column 4, the other end of the support column 4 is fixedly provided with the outer support sleeve 3, and the outer support sleeve 3 is bonded to the rubber sleeve 6. Multiple sets of heat dissipation fins 5 are fixedly provided on the outer surface of the inner support sleeve 2. By setting up the support mechanism, the cable and the rubber sleeve 6 can be fixedly supported, such as ensuring the internal cavity space of the rubber sleeve 6, and the heat dissipation fins 5 can absorb the temperature on the cable, thereby reducing the temperature on the cable.

[0020] In other embodiments, the closing mechanism includes a mounting frame 9, a movable rod 10, a return spring 11, and a rubber plug 12. The mounting frame 9 is fixedly connected to the rubber sleeve 6. The movable rod 10 is slidably connected inside the mounting frame 9. The return spring 11 is sleeved on the outer surface of the movable rod 10. The top end of the movable rod 10 is fixedly provided with the rubber plug 12, and the rubber plug 12 is engaged with the through hole groove 8. One end of the return spring 11 is fitted against the bottom of the rubber plug 12, and the other end of the return spring 11 is fitted against the inner side of the mounting frame 9. By setting the closing mechanism, through... Pushing the rubber plug 12 downwards causes the return spring 11 to undergo elastic deformation. Simultaneously, as the rubber plug 12 moves, it can drive the movable rod 10 downwards. At this time, the cold air pipe head is inserted into the through hole groove 8, which can inject cold air into the rubber jacket 6, thereby improving the physical cooling effect of the cable. When the cold air pipe head separates from the through hole groove 8, the rubber plug 12 can be moved under the elastic deformation of the return spring 11, causing the rubber plug 12 to engage with the through hole groove 8. In this way, the cold air inside the rubber jacket 6 can be retained inside, thereby improving the cooling effect of the cable.

[0021] In other embodiments, the cross-section of the rubber plug 12 is T-shaped, and the inner diameter of the through-hole groove 8 is adapted to the upper cross-sectional diameter of the rubber plug 12. By setting the shape of the rubber plug 12, the tail end of the rubber plug 12 can be prevented from being limited after it is inserted into the through-hole groove 8. The matching size of the through-hole groove 8 and the rubber plug 12 can ensure that the rubber plug 12 fits more closely when inserted into the through-hole groove 8, so that the rubber plug 12 can tightly fit and seal the through-hole groove 8.

[0022] In other embodiments, wear-resistant protrusions 7 are fixedly provided on the outer surface of the rubber jacket 6, and a plurality of wear-resistant protrusions 7 are provided; by providing a plurality of wear-resistant protrusions 7, the wear resistance of the outer surface of the rubber jacket 6 can be improved, thereby improving the service life of the rubber jacket 6.

[0023] In other embodiments, the heat dissipation fins 5 are made of copper; by limiting the material of the heat dissipation fins 5, the heat conduction effect of the heat dissipation fins 5 can be maximized.

[0024] In other embodiments, a heat-insulating coating is provided on the inner side of the rubber jacket 6, and the main material of the heat-insulating coating is glass wool; by providing a heat-insulating coating, the temperature on the outside of the rubber jacket 6 can be prevented from directly increasing the temperature of the cable inside the rubber jacket 6, thus achieving a heat insulation effect.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
