Abstract

The utility model discloses a kind of physically-foamed coaxial cable, its key is：Including conductor, the insulating barrier being coated on outside conductor and the sheath being coated on outside insulating barrier, anti-interference layer and screen layer are coated with successively from inside to outside between the insulating barrier and sheath.A kind of physically-foamed coaxial cable of the utility model, anti-tampering and shield effectiveness is good, decays small, capacitive property is good, and transmission quality is high.

Description

Physically-foamed coaxial cable

Technical field

The utility model belongs to field of cable technology, specifically, is related to a kind of physically-foamed coaxial cable.

Background technology

Electric wire is to transmit electromagnetic energy, information and realize the wire product of electromagnetic energy conversion, the electric wire of broad sense Cable is also referred to simply as, the cable of narrow sense refers to insulated cable, and it may be defined as：The aggregate being made up of following part；One or Many insulated wire cores, and the clad that each of which may have, total protective layer and outer jacket, cable, which can also have, additional not to be had There is the conductor of insulation；Electric wire is widely used in appliance equipment, illuminating line, family expenses as the main carriers of power transmission In terms of electrical equipment, the quality of its quality directly influences construction quality and the security of the lives and property of consumer, commercially has very Many electric wire kinds, be according to the power load of oneself come using suitable electric wire.Existing clad to the anti-tampering of conductor and Shielding action effect is not good.

Utility model content

To solve above technical problem, the purpose of this utility model is to provide a kind of physically-foamed coaxial cable, prevents dry It is good with shield effectiveness to disturb, and decays small, capacitive property is good, and transmission quality is high.

The utility model purpose is realized in：A kind of physically-foamed coaxial cable, its key is：Including conductor, The insulating barrier being coated on outside conductor and the sheath being coated on outside insulating barrier, are wrapped successively from inside to outside between the insulating barrier and sheath It is covered with anti-interference layer and screen layer.Using said structure, through using discovery, single choice selects screen layer or the effect of anti-interference layer does not have There are anti-interference layer and screen layer that effect is used in combination more preferable.

Above-mentioned conductor diameter and thickness of insulating layer, anti-interference layer thickness, the ratio of screen layer thickness in monolayer are 1：(4.8)： (0.2)：(0.14).Using said structure, the thickness of each layer can be increased on year-on-year basis according to different conductor, can be effectively ensured it is anti-tampering and Shielding action effect.

Above-mentioned screen layer is 1 layer or 2 layers.Using said structure, the layer of screen layer can be increased according to external environment needs Number, but cross and can at most increase cost, and shield effectiveness is also without being obviously improved.

Above-mentioned anti-interference layer is plastic-aluminum combined belt, and the screen layer is tincopper fuse wire braided armor.Using said structure, aluminium The combination of plastic composite strip layer and tincopper fuse wire braided armor can be good at complementation, improve anti-tampering and shield effectiveness, reduction decay.

Above-mentioned insulating barrier is polyethylene foam layer.

The foaming degree of above-mentioned polyethylene foam layer is 68~70%.

Above-mentioned sheath is pvc sheath.

Beneficial effect：

A kind of physically-foamed coaxial cable of the utility model, anti-tampering and shield effectiveness is good, decays small, capacitive property is good, Transmission quality is high.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Wherein 1 it is conductor, 2 be insulating barrier, 3 be anti-interference layer, 4 be screen layer, 5 is sheath.

Embodiment

With reference to embodiment and accompanying drawing, the utility model is described in further detail.

Embodiment：

As shown in Figure 1：A kind of physically-foamed coaxial cable, by conductor 1, insulating barrier 2, anti-interference layer 3,1 layer of and of screen layer 4 Sheath 5 is constituted, and the insulating barrier 2 is coated on outside conductor 1, and the anti-interference layer 3 and screen layer 4 are coated on absolutely successively from inside to outside Outside edge layer 2, the sheath 5 is arranged and outermost layer.The anti-interference layer 3 is plastic-aluminum combined belt, and the screen layer 4 is tin-coated copper Silk braiding layer.The insulating barrier 2 is polyethylene foam layer.The foaming degree of the polyethylene foam layer is 68~70%.It is described Sheath 5 is pvc sheath 5.The diameter of conductor 1 and the thickness of insulating barrier 2, the thickness of anti-interference layer 3, the thickness in monolayer of screen layer 4 Ratio be 1：4.8：0.2：0.14.

Finally it should be noted that foregoing description is only preferred embodiment of the present utility model, the common skill of this area Art personnel on the premise of without prejudice to the utility model objective and claim, can make under enlightenment of the present utility model Represented as multiple types, the number of plies of such as each layer, such conversion is each fallen within protection domain of the present utility model.
