Description
Technical field
The utility model relates to field of cable technology, the waterproof coaxial electrical of specific 4G epoch communication apparatus data transmission system
Cable.
Background technology
Cable is widely used in power, communication transmission, with the continuous development of technology, the complexity of the applicable occasion of cable
Change, diversification.Coaxial cable is during laying and operation, when mechanical stress or external force cause cable cover(ing) damage or joint failure
When, moisture or moisture can longitudinally and radially gap be immersed along cable, and cable insulation is caused to make moist aging.Meanwhile there is moisture
Immersion may result in conductor indium, increases the contact resistance between conductor single line to increase cable conductor resistance, cable is caused to pass
Defeated penalty.Original big specification coaxial cable generally uses naked copper or copper line pipe or Copper covered steel material as conductor, cost
Higher, insulating generally uses foamed insulation, and is woven using copper wire or tinned copper wire, and does not have water-fast and use in the seawater
Function.
Utility model content
The problem of for background technology, the utility model provides waterproof coaxial-cable, it is intended to reduce original electricity
Cable cost mitigates cable laying weight so that has test frequency range high (4G), low medium, low loss characteristic, excellent connectivity
Can, and can be used in a wider context using cable.
To achieve the above object, the utility model provides the following technical solutions：Waterproof coaxial-cable, including from inside to outside according to
Secondary to be equipped with conductor, insulating layer, outer conductor and oversheath, the outer conductor is made of self-adhesion aluminium foil, braiding layer and marine glue, institute
It states and is equipped with shielded layer between insulating layer and oversheath, it is three layers of skin foam skin that the conductor, which uses copper clad aluminum material, the insulating layer,
Structure, specifically：Cortex is low density polyethylene layer, alveolar layer is mixed type polyethylene foamed material, exodermis is high density polyethylene (HDPE)
Layer, the braiding layer are aluminum-magnesium alloy wire braiding layer, are connect with oversheath by being full of marine glue.
The core conductor is sub-thread copper clad aluminum, and diameter is more than 1.42mm.
The count of the aluminum-magnesium alloy wire braiding layer is more than 88%.
One layer of adhesive layer is also coated between the conductor and insulating layer.
The oversheath is pe sheath.
Compared with prior art, the utility model has the beneficial effects that：The utility model uses copper clad aluminum as conductor, greatly
Cable cost is reduced greatly, while reducing wire rod weight, is suitable in water or use waterborne.Insulation uses skin foam skin works
Foamed insulation is managed, outer conductor is changed to aluminum-magnesium alloy wire, while adding marine glue, prevents moisture from carrying out in cable so as to have
Test frequency range high (4G), low medium, low loss characteristic, excellent switching performance.
Description of the drawings
Fig. 1 is the utility model embodiment sectional view；
In figure：The single copper clad aluminum conductors of 1-；2- skin foam skin foamed insulations；3- shielding self-adhesion aluminium foils；4- aluminum-magnesium alloy wires

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment：
Referring to Fig. 1, the utility model provide waterproof coaxial-cable structure, including from inside to outside successively be equipped with conductor, absolutely
Edge layer, outer conductor and oversheath, the outer conductor are made of self-adhesion aluminium foil, braiding layer and marine glue, the insulating layer with it is outer
Shielded layer is equipped between sheath, it is skin foam skin three-decker that the conductor, which uses copper clad aluminum material, the insulating layer, specifically：Skin
Layer is low density polyethylene layer, alveolar layer is mixed type polyethylene foamed material, exodermis is high-density polyethylene layer, the braiding layer
For aluminum-magnesium alloy wire braiding layer, it is connect with oversheath by being full of marine glue
Specific is to be equipped with single copper clad aluminum conductor 1, skin foam skin foamed insulation 2, shielding self-adhesion aluminium successively from inside to outside
Foil 3, aluminum-magnesium alloy wire braiding layer 4, marine glue 5 and PE oversheaths 6；
