Description

A kind of equipment room shielded multiconductor cable

Technical field

The utility model relates to field of cable technology more particularly to a kind of equipment room shielded multiconductor cables.

Background technique

Radio-frequency cable is the cable for transmitting electromagnetic energy in radio-frequency region, is various radio communications systems and electronic equipment In indispensable element, wireless communication with broadcast, TV, radar, navigation, computer and in terms of answered extensively With.Currently, mobile communication, network technology equipment room are mostly single radio-frequency cable connection in general computer room, in cabling mistake Cheng Zhong needs repeatedly to be laid with as required, install, connect, winding displacement it is extremely inconvenient, construction material is at high cost, low efficiency, repeats labor It is dynamic.

Summary of the invention

The utility model aims to solve the problem that the deficiencies in the prior art, and provides that a kind of structure is simple, equipment room easy to use Shielded multiconductor cable.

In order to achieve the above object, the utility model adopts the following technical solutions: a kind of equipment room shielded multiconductor cable, including 7 coaxial cable cores, the cable core include tinned copper wire conductor, the periphery of tinned copper wire conductor from the inside to the outside according to Secondary cladding insulating layer divides aluminium strip layer, sub-shield, inner restrictive coating, the sub-shield by 8 gangs of diameter 0.1mm tinned copper wire Braiding constitute, seven cable core entirety peripheries from the inside to the outside successively coat polyester layer, total aluminium strip layer, total screening braid, External sheath layer, total screening braid are made of the braiding of the tinned copper wire of 10 gangs of diameter 0.1mm, inner restrictive coating and external sheath layer For low-smoke halogen-free polyolefin layer, divide the aluminium face of aluminium strip layer and total aluminium strip layer outwardly.

Preferably: 7 cable cores are arranged as three layers, and from top to bottom every layer number is respectively 2,3,2, and upper and lower 2 adjacent cable cores are staggered.

Preferably: the insulating layer is polyethylene foam layer.

The beneficial effects of the utility model are: the utility model structure novel is special, more coaxial radio-frequency cable cores, Perfect combination together, improves integration degree, uses convenient for whole；Shielding properties is superior, and cable takes double layer screen, both It ensure that transmission shielding of each signal in single coaxial radio-frequency cable, also prevent interacting between multiple signals, again Outside core plus total shielded layer is filled, to enhance the anti-external disturbance ability of Integral cable；Overall volume is small, and cable is by multi cord Core is twisted into circular configuration, and size reduces, compact-sized, easy for installation.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1- tinned copper wire conductor；2- insulating layer；3- divides aluminium strip layer；4- sub-shield；5- inner restrictive coating；6- polyester Layer；The total aluminium strip layer of 7-；The total screening braid of 8-；9- external sheath layer.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples:

As shown in Figure 1, the utility model includes 7 coaxial cable cores, the cable core includes that tinned copper wire is led Body 1, the periphery of tinned copper wire conductor 1 from the inside to the outside successively coat insulating layer 2, divide aluminium strip layer 3, sub-shield 4, inner restrictive coating 5, the insulating layer 2 is polyethylene foam layer, and the sub-shield 4 is made of the braiding of the tinned copper wire of 8 gangs of diameter 0.1mm, Seven cable core entirety peripheries successively coat polyester layer 6, total aluminium strip layer 7, total screening braid 8, external sheath layer from the inside to the outside 9, total screening braid 8 is made of the braiding of the tinned copper wire of 10 gangs of diameter 0.1mm, and inner restrictive coating 5 and external sheath layer 9 are low Cigarette halogen-free polyolefin layer divides the aluminium face of aluminium strip layer 3 and total aluminium strip layer 7 outwardly.

7 cable cores are arranged as three layers, and from top to bottom every layer number is respectively 2,3,2, and neighbouring 2 Root cable core is staggered.

Cable conductor uses tinned copper wire conductor 1, then the extrusion of polyethylene foam insulation 2 is become core outside conductor 1, Pass through 16 ingot braiders, longitudinal wrap aluminium strip outside core, aluminium faces out, and formation divides aluminium strip layer 3, while 8 strands are woven outside aluminium strip layer 3 dividing 0.1 millimeter of tinned copper wire of diameter forms sub-shield 4, and low-smoke halogen-free polyolefin material is extruded outside it, constitutes inner restrictive coating 5, Form single core；Then 7 core strandings, then in its outer wrapped polyester layer 6, then by 24 ingot braiders, longitudinal wrap aluminium strip, Aluminium faces out, and forms total aluminium strip layer 7, while 10 strands of diameters, 0.1 millimeter of tinned copper wire is woven outside total aluminium strip layer 7, forms total screen Braiding layer 8 is covered, finally squeezes out external sheath layer 9 using low-smoke halogen-free polyolefin material.

The utility model structure novel is special, and more coaxial radio-frequency cable cores, perfect combination together, improves collection At degree is changed, used convenient for whole；Shielding properties is superior, and cable takes double layer screen, both ensure that each signal single same Transmission shielding in axis radio-frequency cable, also prevents interacting between multiple signals, and outside core plus filled total shielded layer, To enhance the anti-external disturbance ability of Integral cable；Overall volume is small, and multiply core is twisted into circular configuration by cable, and size subtracts It is small, it is compact-sized, it is easy for installation.

The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without Improvement directly applies to other occasions, both is within the protection scope of the present invention.
