Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable with high protection. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a central wire. The entire outside is covered with a highly insulating covering. The cable has internal power. Cables are one of the common circuit components used to transmit electricity, and cables can be laid underground or erected in the air.

[0003] When existing cables laid underground are in use, the cables themselves are easily compressed due to the squeezing of ground objects. When the cables are under pressure for a long time, the inner core of the cables themselves are easily damaged, affecting the normal power transmission of the cables. Although the existing cables themselves are wrapped with a wear-resistant layer, the protective effect is limited. Therefore, we propose a cable with higher protective properties. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a cable with higher protection.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a cable with high protectiveness, including a conductor core and an insulating sleeve, wherein the conductor core and the insulating sleeve are fixedly connected and matched by an elastic mesh, and the elastic mesh itself has elastic properties. The interior of the insulating sleeve is filled with an elastic filling material that contacts the outside of the conductor core, the outer cover of the insulating sleeve is provided with an anti-corrosion layer, and the outer cover of the anti-corrosion layer is provided with a wear-resistant component.

[0006] Preferably, when the outer portion of the anti-corrosion layer is pressed against the insulating sleeve, the inner portion of the insulating sleeve is in a state of squeezing the conductive core through the elastic filling material.

[0007] Preferably, when the guide core is squeezed, the guide core is located inside the elastic filling material through the elastic mesh and is in a movable adjustment state.

[0008] Preferably, the wear-resistant component includes a wear-resistant layer, a docking groove, and a buffer ball pad. The wear-resistant layer is sleeved on the outside of the corrosion-resistant layer. The inner side of the wear-resistant layer and the outer side of the corrosion-resistant layer are provided with docking grooves, and a buffer ball pad is provided between every two groups of the docking grooves.

[0009] Preferably, the wear-resistant layer and the docking groove themselves both have deformation characteristics, and the wear-resistant layer and the anti-corrosion layer are elastically snap-fitted via a buffer ball pad.

[0010] Preferably, when the outer portion of the wear-resistant layer is under pressure, the wear-resistant layer is in an extrusion buffering state through the buffer ball pad.

[0011] Preferably, the outer sleeve of the wear-resistant component is wrapped with a steel mesh sleeve, the steel mesh sleeve itself has wear-resistant properties, and the outer sleeve of the steel mesh sleeve is provided with an outer sheath.

[0012] The utility model provides a highly protective cable with the following beneficial effects:

[0013] 1. A cable with high protective properties. In this article, the multiple groups of conductors are movably arranged inside the insulating sleeve, and the surface of the conductors is fixedly connected to the inner side of the insulating sleeve through an elastic mesh. When the cable is buried underground, the wire mesh and the outer sheath can first contact the external soil layer. After the internal pressure of the soil layer is transmitted to the surface of the insulating sleeve, when the insulating sleeve squeezes the conductors inside the elastic filling material, the multiple groups of conductors can be moved and adjusted in position inside the elastic filling material through the elastic mesh to avoid the conductors themselves from being subjected to squeezing force, and the conductors can be pulled accordingly through the elasticity of the elastic mesh itself. The elastic filling material itself is an elastic material. When the conductors move inside the elastic filling material, the elastic filling material can also cushion the conductors, thereby achieving the effect of improving the protective properties of the cable.

[0014] 2. This is a cable with high protection. The outer sheath of the corrosion-resistant layer is provided with a wear-resistant component. The wear-resistant component consists of a wear-resistant layer, a docking groove and a buffer ball pad. The wear-resistant layer and the corrosion-resistant layer are snap-fitted together by multiple groups of buffer ball pads. The wear-resistant layer and the buffer ball pads themselves have deformation characteristics. After the cable is buried underground, the soil inside squeezes the steel mesh sleeve and the surface of the outer sheath, and the steel mesh sleeve will squeeze the outside of the wear-resistant component, and the wear-resistant layer will squeeze the multiple groups of buffer ball pads accordingly. The external extrusion force can be initially reduced through the characteristics of the wear-resistant layer and the multiple groups of buffer ball pads themselves, thereby achieving the effect of assisting in improving the pressure resistance of the cable.

[0024] Furthermore, when the outer portion of the anti-corrosion layer 5 is pressed against the insulating sleeve 2 under pressure, the inner portion of the insulating sleeve 2 is in a state of squeezing the conductive core 1 through the elastic filling material 4 .

[0025] Furthermore, when the guide core 1 is squeezed, the guide core 1 is located inside the elastic filling material 4 through the elastic mesh 3 and is in a movable adjustment state.

[0026] Example 2: A cable with higher protection, such as Figure 1-Figure 3 As shown, it includes a guide core 1 and an insulating sleeve 2.

The outer sleeve of the insulating sleeve 2 is provided with an anti-corrosion layer 5, and the outer sleeve of the anti-corrosion layer 5 is provided with a wear-resistant component 6.

[0027] Furthermore, when the outside of the anti-corrosion layer 5 is under pressure to squeeze the insulating sleeve 2, the inside of the insulating sleeve 2 squeezes the guide core 1 through the elastic filling material 4. When the guide core 1 is squeezed, the guide core 1 is located inside the elastic filling material 4 through the elastic mesh 3 and is in an active adjustment state.

[0028] Furthermore, the wear-resistant component 6 includes a wear-resistant layer 9, a docking groove 10, and a buffer ball pad 11.

[0032] The working principle of this utility model:

[0033] The multiple groups of conductor cores 1 are arranged movably inside the insulating sleeve 2, and the surface of the conductor core 1 is fixedly connected to the inner side of the insulating sleeve 2 through the elastic mesh 3. When the cable is buried underground, the wire mesh 7 and the outer sheath 8 can first contact the external soil layer, and after the internal pressure of the soil layer is transmitted to the surface of the insulating sleeve 2, when the insulating sleeve 2 squeezes the conductor core 1 inside the elastic filling material 4, the multiple groups of conductor cores 1 can be moved and adjusted in position by the elastic mesh 3 inside the elastic filling material 4 to avoid the conductor core 1 itself being subjected to the squeezing force, and the conductor core 1 can be relatively elastic through the elastic mesh 3 itself. To adapt to pulling, the elastic filling material 4 itself is an elastic material. When the guide core 1 is located inside the elastic filling material 4 and moves, the elastic filling material 4 can also buffer the guide core 1, thereby improving the protection of the cable. The outer sleeve of the anti-corrosion layer 5 is provided with a wear-resistant component 6. After the cable is buried underground, the soil inside squeezes the surface of the wire mesh sleeve 7 and the outer sheath 8. The wire mesh sleeve 7 will squeeze the outside of the wear-resistant component 6, and the wear-resistant layer 9 will adapt to the squeezing of multiple groups of buffer ball pads 11. The external extrusion force can be preliminarily reduced through the characteristics of the wear-resistant layer 9 and the multiple groups of buffer ball pads 11.
