Description

Outdoor two sheath net twines of super five types

Technical Field

The utility model relates to the technical field of network cables, in particular to a super-five type outdoor double-sheath network cable.

Background

The category of extra five refers to the category of extra five unshielded twisted pairs and the category of extra five shielded twisted pairs. Unshielded twisted pair cable is constructed from multiple twisted pairs and a plastic sheath. The five categories refer to five different quality classes defined by the international electrical industry association for twisted pair cables, and we first introduce the common types and characteristics of twisted pairs in order to give a relatively comprehensive understanding of twisted pairs. Twisted pairs in computer local area networks can be divided into two broad categories, Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP): the STP is surrounded by a layer of metal material to reduce radiation and prevent eavesdropping of the information. Meanwhile, the device has higher data transmission rate, but higher price and more complex installation; the UTP is not made of metal shielding materials, only wrapped by a layer of insulating rubber, relatively low in price and flexible in networking. UTP is generally used except for the use of STP in wiring in certain special situations (e.g., severe exposure to electromagnetic radiation, high transmission quality requirements, etc.). The UTPs currently used can be classified into 3 types, 4 types, five types, super five types, six types, and super six types. Wherein: the 3-type UTP meets the requirement of Ethernet (10Mbps) on transmission media, and is an important transmission medium in early networks; since the standard of the type 4 UTP is later than that of the type 3 UTP, the transmission performance is not improved much compared with that of the type 3 UTP, so that the type 4 UTP is generally used less; the five types of UTP are the preferred media for fast Ethernet (100Mbps) due to low cost and high quality; the super-five UTP is used in gigabit Ethernet (1000Mbps), and the internal optical fiber is easily damaged by twisting during the use of the current super-five outdoor double-sheath network cable.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a super-five type outdoor double-sheath network cable, which solves the problem that the internal optical fiber is easily damaged by twisting in the use process of the existing super-five type outdoor double-sheath network cable.

Technical scheme

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides an outdoor two sheath net twines of super five types, includes the oversheath, the inside of oversheath is provided with the compound area of plastic-aluminum, the surface of the compound area of plastic-aluminum bonds with the inner wall of oversheath, the inside of the compound area of plastic-aluminum is provided with the water blocking layer, the surface of water blocking layer bonds with the inner wall of the compound area of plastic-aluminum, the inside of water blocking layer is provided with the pine sleeve pipe, the surface of pine sleeve pipe and the inner wall overlap joint of water blocking layer, the inside of pine sleeve pipe is provided with optic fibre, the quantity of pine sleeve pipe is five, is provided with the reinforcing steel wire between five pine sleeve pipes, and five pine sleeve pipes all are provided with the rubber strip each other, the surface of rubber strip bonds with the inner wall of water blocking layer.

Furthermore, water-blocking ointment is filled in the water-blocking layer.

Further, the outer surface of the reinforcing steel wire is overlapped with the surfaces of the five loose tube sleeves.

Furthermore, the number of the rubber strips is five, and the five rubber strips are all triangular.

The utility model provides a super-five type outdoor double-sheath network cable. The method has the following beneficial effects:

1. this outdoor pair of sheath net twine of super five types, through the mutual cooperation of plastic-aluminum composite band, water-blocking ointment and rubber strip, reach and increase net twine waterproof performance, can increase net twine torsional property more simultaneously, reduce the possibility that net twine damaged the optic fibre easily when wrench movement, solved present outdoor pair of sheath net twine of super five types and damaged the problem of inside optic fibre because wrench movement easily in the use.

2. This outdoor two sheath net twines of super five types, through the setting of reinforcing steel wire, reach and increase net twine stretching resistance, avoid the net twine to appear the fifty percent discount and damage optic fibre.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

Wherein, 1 oversheath, 2 plastic-aluminum composite strips, 3 water-resistant layers, 4 loose tubes, 5 optic fibres, 6 reinforced steel wires, 7 water-resistant factice and 8 rubber strips.

Detailed Description

As shown in fig. 1, an embodiment of the utility model provides an ultra-five type outdoor double-sheath mesh wire, which comprises an outer sheath 1, an aluminum-plastic composite tape 2 is arranged inside the outer sheath 1, the outer surface of the aluminum-plastic composite tape 2 is bonded with the inner wall of the outer sheath 1, a water-blocking layer 3 is arranged inside the aluminum-plastic composite tape 2, water-blocking ointment 7 is filled inside the water-blocking layer 3, the outer surface of the water-blocking layer 3 is bonded with the inner wall of the aluminum-plastic composite tape 2, a loose tube 4 is arranged inside the water-blocking layer 3, the surface of the loose tube 4 is lapped with the inner wall of the water-blocking layer 3, optical fibers 5 are arranged inside the loose tube 4, the number of the loose tube 4 is five, reinforcing steel wires 6 are arranged among the five loose tube sleeves 4, the outer surface of each reinforcing steel wire 6 is lapped with the surfaces of the five loose tube sleeves 4, rubber strips 8 are arranged among the five loose tube sleeves 4, the surface of each rubber strip 8 is bonded with the inner wall of the water-blocking layer 3, the number of the rubber strips 8 is five, and the five rubber strips 8 are all triangular.

The working principle is as follows: the net twine twists reverse in the use or when laying, and rubber strip 8 and plastic-aluminum composite band 2 can support anti torsional force this moment, even torsion is big, wait that torsion disappears after, rubber strip 8 and plastic-aluminum composite band 2 can utilize self elasticity in time to reset for the net twine reconversion, avoid the net twine to be in the torsional state for a long time and damage optic fibre 5.
