Abstract
The utility model discloses a producing and extrusion molding mold for combined network cables and special cable protecting layers of the combined network cables, and a combined network cable comprises a coaxial cable and a digital communication five type cable. The utility model is characterized in that the sheath layers of the coaxial cable and the digital communication five type cable are connected into integration by a connecting layer on the middle; the special cable protecting layer producing and extrusion molding mold comprises an inner extrusion molding mold and an outer extrusion molding mold; the inner mold is provided with two mold core pipe-shaped bodies used for the extrusion molding of the sheath layers of the coaxial cable and the digital communication five type cable; the outerl mold is used for the extrusion molding of the connecting layer. Because the coaxial cable and the digital communication five type cable are combined into integration and easily tore connecting layer between the sheath layers, the utility model is convenient for execution and installation can be widely ised for integrated wire laying systems for the repeated wire laying of each system. The combined network cable protecting layer extrusion molding mold provided by the utility model has the advantages of simple structure and convenient use and can ensure the surface quality of the combined network cable protecting layers.
Description
Technical field
The utility model relates to the cable technology field, more specifically to the telecommunication cable technical field.
Background technology
Present five class cables have outstanding electric property in 100MHZ wideband section, can be used for high-speed Internet, various application occasions such as more advanced ATM networks, multimedia network, intelligent building synthesization wiring system.Coaxial cable is the transmission medium that is widely used, and it is good to have a high frequency performance, and it is low to decay, and shielding is excellent, and is waterproof and dampproof, characteristics such as long service life.Although optical fiber cable more and more is subjected to people favor and since at present the finger assignments technical difficulty of optical cable greatly and economically, optical fiber cable is used for long apart from the main line more, distribution network is still based on coaxial cable.In sum, CATV coaxial cable and digital communication 5 class cables will exist in the long duration and develop jointly, the user is low with the efficient that above-mentioned two kinds of cables lay use respectively separately, inconvenient, and in the information age of today, people require to use the synthesization wiring system, with phone, fax, video telephone, Email, video conferencing, fire-proof and theft-proof is reported to the police, the computer networking, closed-circuit television monitors, public broadcasting, building elevator, central air-conditioning, illumination, multiple business such as the automation control of equipment such as energy monitor concentrate in the cover wiring system, and realization information sharing and automatic management avoid each system to repeat wiring.
Summary of the invention
A purpose of the present utility model provides a kind of combinational network cable that coaxial cable and digital communication 5 class cables are integrated.
Realize that this purpose technical scheme is design like this, it comprises coaxial cable, digital communication 5 class cables, it is characterized in that: the articulamentum of the restrictive coating of coaxial cable, digital communication 5 class cables by the centre is combined as and is one.
The cross sectional shape of above-mentioned combinational network cable is " 8 word shapes.
The polyvinyl chloride articulamentum of above-mentioned articulamentum for easily tearing.
Another purpose of the present utility model provides a kind of extruded mould of producing above-mentioned combinational network cable protective layer that is exclusively used in.
Realize that this purpose technical scheme is design like this, it comprises inside and outside extrusion molding mould, and internal mold is provided with two core rod tubular bodies of the restrictive coating extrusion molding that is used for coaxial cable, digital communication 5 class cables, and external mold is used for the extrusion molding of articulamentum.
In order to reduce coaxial cable, digital communication 5 class cable surface shaping resistances, prevent cable core surface crush injury, two core rod tubular bodies on the above-mentioned internal mold are to adopt nested configuration to make.
In order to make the mold work smooth surface, to reduce the frictional resistance between sizing material and the mould, above-mentioned mould adopts carbon steel to make, and core rod is through quenching heat treatment.
The utility model is owing to be integrated coaxial cable and digital communication 5 class cables, and the articulamentum between the restrictive coating easily tears, and is convenient to construction and installation; Can be widely used in comprehensive wiring system, avoid each system to repeat wiring, make the increase and decrease of telecommunication apparatus and resettlement very convenient; Help realizing information sharing and automatic management, help the application that the electronic computer and the communication technology combine.The extruded mould that is exclusively used in the above-mentioned combinational network cable protective layer of production that the utility model provides is simple in structure, easy to use, can guarantee the surface quality of combinational network cable protective layer.
