A kind of shielded cable of 5g communication with two halves circle core is provided, including insulating layer, is filled in insulating layer
Interior conductor, it is characterized in that: the insulating layer includes the first insulating layer and second insulating layer, the cross section of first insulating layer
Cross section with the second insulating layer is that the identical sealing of size is semicircle, the semicircular diameter of first insulating layer
It is mutually aligned and is bonded to be spliced into circle, first insulating layer and institute with the semicircular diameter of the second insulating layer
State second insulating layer and fill several conductors respectively, the outer surface of the insulating layer by it is interior be successively coated with outward it is wrapped
Layer, braiding layer and sheath.
Wherein, the material of the insulating layer is 90 DEG C of environmentally friendly crosslinked polyethylene material.
Wherein, the conductor is bare copper conductor, and the outer diameter of the every bare copper conductor is 0.2~0.5cm.
Wherein, it several conductors for being filled in first insulating layer and is filled in several in the second insulating layer
A conductor is twisted by synnema and is pressed into semicircle.
Wherein, first insulating layer and the second insulating layer are two insulating layers that color is different.
Wherein, the wrapping layer is entwined using polyester belt.
Wherein, the braiding layer is woven by tin-coated copper plated aluminium alloy wire.
Wherein, the outer diameter of tin-coated copper plated aluminium alloy wire is 0.1~0.2cm, and the count of the braiding layer is no less than
60%.
Wherein, the sheath is 90 DEG C of low-smoke bittern-free highly fire-proof polyolefin.
The utility model has the beneficial effects that
The first insulating layer and second insulating layer where conductor are semicircles, can be spliced to form a circle, are avoided existing
There is technology to increase gasket for packing support into round problem, the outer diameter of entire cable can be greatly reduced in this way, so that entirely
Shielded cable structure becomes smaller, weight, and reduces braided wires, sheath and gasket for packing dosage, reduces production cost, the outside diameter of cable
Reduction can make the shield effectiveness between conductor more preferable, improve the electromagnetism interference performance of cable.
