Technical Field

The utility model relates to the technical field of cables, specifically be an aerial insulated cable of increase-volume.

Background

The cable is an electric energy or signal transmission device, and generally comprises several or several groups of conducting wires, and the cable comprises a power cable, a control cable, a compensation cable, a shielding cable, a high-temperature cable, a computer cable, a signal cable, a coaxial cable, a fire-resistant cable, a marine cable, a mining cable, an aluminum alloy cable and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like.

Among the prior art, aerial insulated cable need unsettled setting at the laying process, and under the strong wind weather, unsettled cable swings with the wind, leads to tensile easily, arouses the cable damage.

SUMMERY OF THE UTILITY MODEL

The utility model provides an overhead insulated cable of increase-volume to solve the problem in the background art.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a but aerial insulated cable of increase-volume, includes the sinle silk, the outside of sinle silk is provided with the inner protective housing, the outside of inner protective housing is provided with the insulating layer, the reinforcing ring has been cup jointed on the surface of insulating layer, the draw-in groove has been seted up on the surface of reinforcing ring, the outside of reinforcing ring is provided with the latch, the outside of insulating layer is provided with the strengthening rib strip, the outside of strengthening rib strip is provided with outer protective housing, the outside of outer protective housing is provided with the wearing layer.

Furthermore, the surface of the insulating layer is provided with a groove structure, the reinforcing ring is fixed in the groove structure, and the inner wall of the groove structure is provided with a protrusion which is clamped with the clamping groove.

Furthermore, the latch all sets up in the reinforcement ring outside, the strengthening rib strip joint is between the latch.

Furthermore, the reinforcing ribs are provided in a plurality, and the plurality of reinforcing ribs are spirally wound.

Further, the inner diameter of the inner protection shell is larger than the outer diameter of the wire core.

Compared with the prior art, the utility model provides a but aerial insulated cable of increase-volume possesses following beneficial effect:

this but built on stilts insulated cable of increase-volume forms anti extrusion structure inside the cable through setting up the strengthening ring, and the outside winding of strengthening ring sets up the strengthening rib strip, utilizes the torsion that the winding produced between the strengthening rib strip, improves stretch-proofing performance, and then improves the resistance of cable under strong wind weather.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion A of FIG. 1;

fig. 3 is a schematic view of the insulating layer structure of the present invention.

In the figure: 1. a wire core; 2. an inner protective shell; 3. an insulating layer; 4. a reinforcing ring; 5. a card slot; 6. clamping teeth; 7. reinforcing ribs; 8. an outer protective shell; 9. and a wear-resistant layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, the utility model discloses a but overhead insulated cable of increase capacity, including sinle silk 1, the outside of sinle silk 1 is provided with inner protective housing 2, the outside of inner protective housing 2 is provided with insulating layer 3, reinforcing ring 4 has been cup jointed on the surface of insulating layer 3, draw-in groove 5 has been seted up on the surface of reinforcing ring 4, the outside of reinforcing ring 4 is provided with latch 6, the outside of insulating layer 3 is provided with strengthening rib 7, strengthening rib 7's outside is provided with outer protective housing 8, outer protective housing 8's outside is provided with wearing layer 9.

Specifically, the surface of the insulating layer 3 is provided with a groove structure, the reinforcing ring 4 is fixed in the groove structure, the inner wall of the groove structure is provided with a protrusion, and the protrusion is connected with the clamping groove 5 in a clamping manner.

In this embodiment, reinforcing ring 4 passes through 3 surface grooves on the insulating layer to be fixed in insulating layer 3 outsidely, forms bearing structure simultaneously, improves the anti extrusion capacity of cable.

Specifically, latch 6 all sets up in reinforcing ring 4 outside, strengthening rib 7 joint is between latch 6.

In this embodiment, the latch 6 outside the reinforcing ring 4 plays a fixed role in the position of the reinforcing rib 7, and prevents the dislocation of the reinforcing rib 7.

Specifically, the reinforcing ribs 7 are provided in plural, and the plural reinforcing ribs 7 are spirally wound.

In this embodiment, the reinforcing ribs 7 arranged in a spiral shape are attached to each other, and the tensile resistance of the cable is improved by using the torsion force when the cable is stretched.

Specifically, the inner diameter of the inner protection shell 2 is larger than the outer diameter of the wire core 1.

In this embodiment, the diameter of the wire core 1 is smaller than the inner diameter of the inner protective shell 2, so that a certain redundant space is formed, and the doubling capacity-increasing is facilitated.

In summary, the capacity-increased overhead insulated cable forms an anti-extrusion structure inside the cable by arranging the reinforcing ring 4, the reinforcing ribs 7 are wound outside the reinforcing ring 4, and the tensile resistance is improved by using the torsion generated by winding between the reinforcing ribs 7, so that the resistance of the cable in strong wind weather is improved.

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