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 first embodiment is as follows: as shown in fig. 1-2, the heat dissipation sheath comprises a heat dissipation sheath 1; a steel strand 101 is arranged in the middle of the heat dissipation sheath 1; cable cores 102 are uniformly arranged on the periphery of the upper part of the heat dissipation sheath 1; the cable core 102 is formed by stranding a plurality of copper stranded wires; the cable core 102 is externally covered with an insulating sheath 2; the heat dissipation sheath 1 consists of a central sheath 103, a positioning sleeve 104, an inner protecting plate 105 and an outer protecting plate 106; the central sleeve 103 is sleeved outside the steel strand 101; the positioning sleeve 104 is sleeved outside the insulating sheath 2; the central sleeve 103 and the positioning sleeve 104 are connected through an inner guard plate 105; the positioning sleeves 104 are connected through an outer protective plate 106; a surface layer sheath 3 is arranged outside the heat dissipation sheath 1; a positioning bulge 107 is arranged on one side of the positioning sleeve 104; the positioning sleeve 104 is clamped with the surface layer sheath 3; an elastic filler 108 is arranged between the heat dissipation sheath 1 and the surface layer sheath 3; buffer through grooves 301 are uniformly formed in the periphery of the upper portion of the surface layer sheath 3.

During the use, as shown in fig. 1-2, the user is using the utility model discloses the cable of making, when the cable receives external force and assaults, take place elastic deformation through inner casing 105 and outer casing 106, thereby play the effect of buffering power consumption, the inside cable linearity of protection cable can not receive destruction, and there is great space between inner casing 105 and the outer casing 106, after cable core 102 live time is longer, when producing more heat, can effectively discharge through this through-hole, thereby prevent the overheated condition of spontaneous combustion of being qualified for the next round of competitions of cable, and be provided with elastic filler 108 at outer casing 106 and top layer sheath 3, thereby both reduce the holistic weight of cable, can increase the pliability of cable again, and 3 upper portions of top layer sheath still evenly open have buffering logical groove 301, it can further increase the pliability and the shock resistance of cable.
