Description
Technical field
The utility model is related to radio frequency coaxial-cable technical field, in particular to a kind of bend resistance radio frequency coaxial-cables.
Background technology
Coaxial cable is widely used in cable TV transmission network network system, closed-circuit television system, monitoring system, safety precaution
In the wire transmission network system such as system, it as backbone, main line or service main, transmission television image, sound, data,
The information such as symbol are also applied in the wire transmission network of other impedance matchings of similar applications, are more suitably applied to lay
In the environment of condition rather harsh, reach good laser propagation effect.As people’s lives level is continuously improved, to obtain more
True transmission information, the requirement to coaxial cable are also higher and higher.For example the requirement for bend resistance ability is with regard to higher and higher,
Radio frequency coaxial-cable in the prior art, Supporting Media of the insulating layer as radio frequency coaxial-cable generally use solid polytetrafluoro
The materials such as ethylene or polyethylene, high-foaming polytetrafluoroethylene (PTFE) or polyethylene cause the bend resistance ability of radio frequency coaxial-cable to exist
Certain restriction limits its popularization and application.
Utility model content
The purpose of this utility model is to provide a kind of bend resistance radio frequency coaxial-cable, has bend resistance intensity height, characteristic resistance
Anti- feature low, simple in structure, easy to process and of low cost.
The utility model can be achieved through the following technical solutions：
The utility model discloses a kind of bend resistance radio frequency coaxial-cables, including be arranged from the inside to the outside inner wire, insulation
Layer, shielded layer and oversheath, the insulating layer inside are honeycomb structure, and the honeycomb of the insulating layer is equipped with several big
The small honeycomb hole to differ, the honeycomb hole inside, which is run through, several wires.By using honeycomb structure in insulating layer, protecting
Under the premise of the enabling capabilities for having demonstrate,proved insulating layer, wire of the setting inside it in honeycomb hole, wire is in honeycomb hole
Inside had not only formed secondary structure support, but also gave full play to the strong feature of bend resistance ability of wire, to keep RF coaxial electric
Cable has stronger bend resistance ability；By the way that wire is arranged inside honeycomb hole, avoid promoting radio frequency coaxial-cable bending resistance
The folding ability of dielectric constant while to(for) insulating layer impacts, and prevents characteristic impedance raising from being caused for radio frequency coaxial-cable
Performance influences；In structure design, it is only necessary to carry out special knot for insulating layer on the basis of conventional radio frequency coaxial cable
Structure design can be met the requirements, and structure design is very simple；Honeycomb hole uses structure setting not of uniform size, reduces processing
Difficulty, wire effectively increases the convenience of processing through the link for simplifying processing in the inside of insulating layer is arranged.
Further, the shielded layer inner wall is equipped with copper foil layer or aluminium foil layer.Both copper foil and aluminium foil had been utilized in shielded layer
Screening ability, further ensured the ability resistant to bending of radio frequency coaxial-cable.
Further, the outer wall of the shielded layer is equipped with copper strips and wraps layer.Both copper strips had been utilized and has wrapped layer in shielded layer
Screening ability has further ensured the ability resistant to bending of radio frequency coaxial-cable.
Further, the oversheath is metal armour tube boot or organic establishment crust, further promotes RF coaxial electricity
The resist bending ability of cable.
Further, the inner wire is sub-thread or multiply oxygen-free copper-wire.
A kind of bend resistance radio frequency coaxial-cable of the utility model has following advantageous effect：
The first, bend resistance ability is strong, by using honeycomb structure in insulating layer, in the enabling capabilities that ensure that insulating layer
Under the premise of, wire of the setting inside it, wire had both formed secondary structure branch inside honeycomb hole in honeycomb hole
It supports, and the feature that the bend resistance ability for giving full play to wire is strong, to enable radio frequency coaxial-cable that there is stronger bend resistance
Power；
The second, characteristic impedance is low, by the way that wire is arranged inside honeycomb hole, avoids promoting radio frequency coaxial-cable bending resistance
The folding ability of dielectric constant while to(for) insulating layer impacts, and prevents characteristic impedance raising from being caused for radio frequency coaxial-cable
Performance influences；
It is third, simple in structure, in structure design, it is only necessary to be directed to insulating layer on the basis of conventional radio frequency coaxial cable
Carrying out special structure design can meet the requirements, and structure design is very simple；
4th, easy to process, honeycomb hole uses structure setting not of uniform size, reduces the difficulty of processing, wire passes through
The link set and simplify processing in the inside of insulating layer is worn, the convenience of processing is effectively increased；
5th, of low cost, the overall structure of bend resistance radio frequency coaxial-cable is similar with conventional RF coaxial cable, for
Material also without particular/special requirement, effectively reduces manufacturing cost.
