Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: as shown in fig. 1 to 4, the cable comprises a cable core 1, an insulating sheath 2 and an outer sheath 3; the cable cores 1 are arranged on two sides in the outer sheath 3; the outer side of the cable core 1 is wrapped with an insulating sheath 2; the insulating sheath 2 is wrapped by a metal sheath 201; an outer sheath 3 is arranged outside the metal sheath 201; the two longitudinal sides of the outer sheath 3 are provided with protective ears 301; a plurality of protection holes 302 are arranged between the protection ears 301 at two sides; a metal braid layer 303 is arranged between every two adjacent protective holes 302; the metal sheaths 201 on the two sides are connected through a middle metal braid layer 303; a metal sheet 304 is arranged between the metal sheath 201 and the outer sheath 3 on two sides; the metal sheet 304 is wrapped in part of the metal sheath 201 in the middle; two sides of the metal sheet 304 are arranged on the inner walls of the protection lugs 301 at two sides; the insulating sheath 2 is made of high-temperature vulcanized silicone rubber; the outer sheath 3 adopts irradiation cross-linked polyolefin; the metal sheath 201 is woven by zinc-plated copper tows; the metal braided layer 303 is braided by zinc-plated copper tows; the metal sheet 304 is made of copper; two sides of the metal sheet 304 are provided with tooth-shaped heat dissipation parts 305 at the inner wall parts of the protection ears 301.

In use, as shown in fig. 1-4, the cable core 1 generates heat energy to diffuse to the outside of the cable core 1 in use, because the metal sheath 201 is disposed outside the insulating sheath 2, and the heat conductivity of the metal sheath 201 is better than that of other parts of the cable, after the heat energy is conducted to the metal sheath 201, the heat energy is preferentially conducted along the metal sheath 201, on one hand, the heat energy is conducted to the metal braided layers 303 in the middle of the two cable cores 1 along the metal sheath 201, because the protecting holes 302 are disposed between the metal braided layers 303, the heat energy can diffuse to the air through the protecting holes 302, the heat energy can be diffused to the air along the tooth-shaped heat dissipating part 305 when the heat energy is conducted to the tooth-shaped heat dissipating part 305 located on the inner wall of the protecting ear 301 to make the heat energy of the cable diffuse to the air rapidly, the life of extension cable, the protection ear 301 that sets up in outer sheath 3 both sides can protect the cable when receiving the external impact, absorb the strength deformation of striking by protection ear 301, make cable core 1 can not receive the direct impact of striking when the collision the very first time, thereby the continuous normal work of cable core 1 has been protected, and the protection hole 302 that sets up at two cable cores 1 middle parts, can guarantee that cable core 1 receives when striking or colliding, further absorb the strength of collision, further protection cable core 1 is not strikeed by the strength of striking, the continuous long-time work of cable has been guaranteed.
