Description
Technical field
The utility model is related to a kind of cable for digital communication more particularly to a kind of with flat structure and heavy seal coat
Cable for digital communication.
Background technology
With the rise of broadband connections access network construction, cable for digital communication preferably transmits matchmaker as information superhighway
The high information departments of a variety of high-tech and the industry such as be situated between and be widely used in government, financial institution, military affairs, medical treatment, consulting industry；Number
Word communication cable not only needs to have excellent digital information transmission performance, but also to have extensive environmental suitability, and
Convenient for laying installation.
Existing cable for digital communication mostly uses traditional circular configuration, which is to be coated with packet in twisted pair wire group
Belt, shielded layer and outer jacket, there are many deficiencies in actually laying for the digital signal cable of this structure：It is primarily due to existing
The outer jacket of digital signal cable be only to be extruded by plastics, thus dislocation is easily deformed after pressure-bearing, Bu Nengcheng
By extraneous pressure, it is easy to compressive deformation is caused, and for cable for digital communication, to the mutual position of the insulated single wire in line group
It sets the change with structural parameters such as pitches and will have a direct impact on the electricity function indexs such as transmission frequency and the bandwidth of cable, to band
Carry out the severe exacerbation of electrical property.Secondly round communication cable direction stationarity is also poor, it is difficult to carry out firm laying and fix, especially
It is difficult even more fixed that it, which is when a plurality of cabling being needed to be arranged in juxtaposition, is susceptible to crimp and twisted deformation, both influenced
Transmission performance, and influence the service life and laying appearance of cable.
Utility model content
For the above-mentioned deficiency present in the prior art, the technical problem to be solved by the utility model is to provide one kind to add
Not only there is good extrusion capability, cable core structure to stablize, and laid convenient for cable for the flat cable for digital communication of strong type, outside
See regular beauty.
In order to solve the above-mentioned technical problem, the reinforced flat cable for digital communication of the utility model, including cable core, it is described
Cable core is made of two pairs of twisted pair wire groups, and two pairs of twisted pair wire groups are arranged in parallel, and each twisted pair wire group is by two insulated single wires
It is mutually twisted, is coated with core protective layer, line group shielded layer and band protective layer successively inside-out in twisted pair wire group；
It is provided with metal shielding outside two pairs of twisted pair wire groups, is set on the metal shielding there are two opposite metal folding slot, the gold
Belong to bending slot to be located between two pairs of twisted pair wire groups, outer jacket is extruded in metal shielding.
In said structure, due to being provided with metal shielding outside two pairs of twisted pair wires, which enhances pair
The anti-pressure ability of twisted wire group ensure that the structural stability of twisted pair wire group, and there are two phases for setting especially on metal shielding
To metal folding slot, which is located between two pairs of twisted pair wires, and bending slot greatly improves the resistance to compression of cable, resists again
Bending intensity is effectively protected the twisted pair wire group in metal shielding, to ensure mutual alignment, the pitch of twisted pair wire group
The stabilization of equal structural parameters, enables cable for digital communication to keep stable high-transmission frequency and transmitting bandwidth, realizes data-signal
Safe and reliable transmission, while metal shielding and metal folding slot also greatly strengthen the mechanical performance of cable.Also due to
Metal shielding is provided with outside twisted pair wire group, which constitutes one layer of special shielding construction again, both enhanced to
The ability of anti-outside electromagnetic interference, and the electromagnetic radiation of cable itself is effectively controlled, not only ensure that cable for digital communication signal passes
Defeated safety, reliability, nor the interference to surrounding devices and network can be formed, to adapt to more requirements at the higher level
Use occasion.Due also to two pairs of twisted pair wire groups constitute flat cable structure, can be easier close to being laid in other objects
It on the horizontal or vertical surface of body, is fixed convenient for the laying of digital signal cable, and fixed will not be formed installs rotation shifting
The smooth beauty of shape is laid in position, and when especially a plurality of electric wire is arranged in juxtaposition, this square cable can realize that gapless is folded
Add, will not only have been formed and mutually squeeze and be twisted deformation, but also makes laying space availability ratio compacter.
Preferred embodiments of the present invention, the insulated single wire include conductor, are coated with insulation successively outside conductor
Endodermis, insulating foam layer and insulation sheath layer.Using skin/bubble/skin insulation layer structure, keep the mutual capacitance between insulated single wire big
Width declines, to make transmission attenuation reduce, on this basis again using the dual shield knot of line group shielded layer and metal shielding
Structure makes cable have the comprehensive shielded effect of preferably anti-inside and outside electromagnetic interference.
Preferred embodiments of the present invention, the metal shielding are fastened by two opposite subdivision structures.It should
Structure had both been convenient for the making of metal shielding, also allowed for the making production of electric wire.
Preferred embodiments of the present invention, the outer jacket extend the metal folding for being embedded in metal shielding indent
In slot.It is closer secured that the structure can be such that outer jacket is bonded with metal shielding, and the machinery for further strengthening cable is strong
Degree.
Preferred embodiments of the present invention are equipped with aerial drainage line between the core protective layer and line group shielded layer.Have
Conducive to performances such as the raising anti-interference, cross-talks of cable.
Description of the drawings
