Abstract

The utility model relates to a framework structure of 6 types of cables, comprising a core (2) and a sheath (1) or a screen layer (1) between the sheath and the core (2); the core (2) comprises 4 conductor groups (3) composed by a pair of conductors (21), an insulating layer (22) outside the conductor; also comprises a framework (25) between 4 conductor groups (3); the framework (25) is in shape of 'V', the bottom end is located in middle of the core (2), two sides respectively separate the adjacent conductor groups (3); the utility model has the instructive effect that: the package can totally adopt Reelex wing ring formation of CAT5E to save the sheath disc which is necessary for original CAT6 package, so that the cable and package are simpler and lighter; transport cost and site construction cost can be reduced to a large extent.

Description

The skeleton structure of 6 class cables

Technical field

The utility model relates to a kind of 6 class cables, relates in particular to the skeleton structure of this 6 class cable.

Background technology

Comprehensive wiring is in a kind of modular, building that flexibility is high or the information transfer channel between the groups of building.It can make voice, data, vision facilities and message exchange equipment and other information management systems be connected with each other, and these equipment are connected with external communication network.It also comprises all cables between building outside wiring network or telecommunication line and the application system equipment and relevant link.Comprehensive wiring is made up of the parts of variety classes and specification, comprising: transmission medium, relevant connection hardware (as distributing frame, connector, socket, plug, adapter) and electric protective equipment etc.These parts can be used to make up various distribution subsystems, and they all have concrete purposes separately, installation not only easy to implement, and can the graceful upgrade with the variation of demand.

But along with the change of time and network application, people recognize that deeply wiring system is the basis of intelligent building, and in close relations with information network mainly lays particular emphasis on the construction of multimedia integration Network Transmission such as phone, data, picture and text, image.Wiring system performance rate and standard are constantly being improved and upgrading along with the development of network communications technology, and this stage wiring system performance rate is to surpass 5 classes (100MHz), and six classes (250MHz) and fiber products are main.

Six classes (250MHz) more and more become the main product of future market comprehensive wiring from present market situation, generally are divided into shielding and non-shielding.

As seen from Figure 1: adopt crossing skeleton to fill the Class 6 cable fabrication scheme in the prior art more than 90%.

Among the figure: core 2 and screen 1 between core 2 and sheath (not shown) or sheath 1; Comprise the cross 23 between insulating barrier 22 that 4 conductor groups 3, conductor that pair of conductors 21 forms are outer and 4 the conductor groups 3 in the core 2.

As seen from Figure 2: the Class 6 cable fabrication scheme that also has sub-fraction to adopt in the prior art is that a character skeleton is filled.

Among the figure: core 2 and screen 1 between core 2 and sheath (not shown) or sheath 1; Comprise the cabinet frame 24 between insulating barrier 22 that 4 conductor groups 3, conductor that pair of conductors 21 forms are outer and 4 the conductor groups 3 in the core 2.

But the technical problem that these schemes all have some to exempt from specific implementation process is not well solved always:

Common crossing skeleton is filled: the line footpath is thicker, and is soft inadequately, can't use the lopping of the Reelex Eight characters, the packed and transported trouble;

One character skeleton is filled: the line footpath is thin, and softness, but structural instability can't be used the lopping of the Reelex Eight characters, the packed and transported trouble, and installation reliability is poor.

Summary of the invention

The utility model technical issues that need to address have provided a kind of skeleton structure of 6 class cables, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: core and screen between core and sheath or sheath; Comprise 4 conductor groups, the outer insulating barrier of conductor that pair of conductors is formed in the core; Also comprise 4 skeletons between the conductor group; Described skeleton is " V " word shape, and its bottom separates contiguous conductor group respectively on central authorities, two limits of core.

Compared with prior art, the beneficial effects of the utility model are: can adopt the Reelex Eight characters lopping of CAT5E fully on manner of packing, reduce the cover dish of the necessary usefulness of original CAT6 packing; Make that cable itself and packing are more succinct, in light weight; Cost of transportation and site operation cost can reduce greatly.

Fig. 2 is the structural representation of a character skeleton 6 type shielding cables in the prior art;

Fig. 3 is a structural representation of the present utility model;

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

As seen from Figure 3: the utility model comprises: core 2 and the screen between core 2 and sheath 1 or sheath 1; Comprise 4 conductor groups 3, the outer insulating barrier 22 of conductor that pair of conductors 21 is formed in the core 2; Also comprise 4 skeletons 25 between the conductor group 3; Described skeleton 25 is " V " word shape, and its bottom separates contiguous conductor group 3 respectively on central authorities, two limits of core 2;

Two limits of described skeleton 25 separate conductor group 3 between left and right and the conductor group 3 between upper left and the lower-left respectively.

The utility model is when installation, and V-shape skeleton softness is tiny, and is in light weight, Stability Analysis of Structures, easier for installation, and stability is high.

Because the utility model puts out the packing material of combustion type because of having used a part less, combustibility is more superior, the coefficient of safety height.

Cross that the utility model is traditional relatively and yi word pattern skeleton are filled, and can adopt the Reelex Eight characters lopping of CAT5E on manner of packing fully. reduced the cover dish of the necessary usefulness of original CAT6 packing.Not only packing cost reduces, and because the cover dish is to be difficult for the pack processing load garbage, does not have the garbage disposal problem of this respect, environmental protection more with the V-type design.

The utility model is because of cable itself and pack more succinct. and in light weight, cost of transportation and site operation cost can reduce greatly.
