AI Technical Summary
Existing power cables have poor tensile strength, resulting in low applicability and safety.
The structure employs multiple grooves, crests, reinforcing rings, and air cavities. The reinforcing rings enhance the connection, the crests deform to reduce the impact of tensile forces, and the air cavities restore their shape to prevent damage.
This improves the cable's tensile strength, prevents damage from pulling, and enhances its practicality and safety.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to cable technical field more specifically, the utility model relates to a kind of tensile power cable structure. BACKGROUND
[0002] Power cable is a kind of wire combination specially designed for transmission and distribution of electric energy, usually by multiple wires stranded, and wrapped with insulation layer and protective layer.
[0003] Although the power cable in the prior art can be used normally, there are still many shortcomings in actual use, such as the tensile effect of the power cable in the prior art is not good enough, and the tensile effect directly determines the use effect of the cable, because the cable will be pulled in most use cases, thus leading to poor applicability and low use safety of the power cable in the prior art. SUMMARY
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the utility model provide a kind of tensile power cable structure, by being provided with multiple gully parts and multiple wave crest parts and reinforcing ring and air cavity and other structures, the utility model has good tensile effect, effectively guarantee the use effect of the utility model, improve the practicability of the utility model, avoid the situation of damage by pulling, ensure the use safety of the utility model, to solve the problems raised in the above background art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a kind of tensile power cable structure, including cable core, the cable core outside is provided with protective layer, the protective layer outside is provided with insulation layer, the insulation layer surface is provided with multiple gully parts and multiple wave crest parts, the gully part inside is adhesively provided with reinforcing ring, the wave crest part inside is provided with air cavity.
[0006] In a preferred embodiment, the cross-sectional shape of the insulation layer is set to be wavy.
[0007] In a preferred embodiment, the air cavity is arranged between the insulation layer and the protective layer.
[0008] Technical effects and advantages of the utility model:
[0009] The utility model has good tensile effect by being provided with multiple gully parts and multiple wave crest parts and reinforcing ring and air cavity and other structures, effectively guarantees the use effect of the utility model, improves the practicability of the utility model, avoids the situation of damage by pulling, and ensures the use safety of the utility model. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is the whole structure schematic diagram of the utility model.
[0011] Figure 2 The utility model discloses a Figure 1 The structure of A part is enlarged and shown schematically.
[0012] The figure mark is: 1, cable core, 2, protective layer, 3, insulation layer, 4, gully part, 5, wave crest part, 6, reinforcing ring, 7, air cavity. DETAILED DESCRIPTION
[0013] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.
[0014] As shown in the accompanying Figure 1 and the accompanying Figure 2 The utility model provides a kind of tensile resistance power cable structure, including cable core 1, the protective layer 2 of cable core 1 outer side is provided with, the insulation layer 3 of protective layer 2 outer side is provided with, the surface of the insulation layer 3 is provided with multiple gully parts 4 and multiple wave crest parts 5, reinforcing ring 6 is adhesively arranged in gully part 4 inside, air cavity 7 is provided in wave crest part 5 inner side.
[0015] The insulation layer 3 is arranged in a wave shape.
[0016] The air cavity 7 is arranged between the insulation layer 3 and the protective layer 2.
[0017] The embodiment is specific: when using the utility model, if pulling, then reinforcing ring 6 will strengthen the connection between the two sides of gully part 4, avoid the problem of damage by pulling, then wave crest part 5 will be deformed under the action of pulling force, reduce the protruding degree of wave crest part 5, so as to reduce the damage effect of pulling force on cable, air cavity 7 can play the role of recovery, when wave crest part 5 is deformed, air cavity 7 will be extruded, after the disappearance of pulling force, air cavity 7 will restore and push wave crest part 5 to restore original state, which makes the utility model have good tensile resistance effect, effectively ensures the use effect of the utility model, improves the practicability of the utility model, avoids the damage by pulling, and ensures the use safety of the utility model.
[0018] The utility model working principle is:
[0019] Refer to the accompanying Figure 1 and the accompanying Figure 2When the utility model is used, the utility model has better anti-pulling effect, effectively guarantees the use effect of the utility model, improves the practicability of the utility model, avoids the damage caused by pulling, and guarantees the use safety of the utility model.
[0020] The last few points to be explained are: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
[0021] Secondly: the utility model discloses the embodiment of the drawings, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, in the case of no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;
