Description
Technical Field
The utility model belongs to the technical field of the cable, concretely relates to novel shielding twisted pair cable.
Background
Twisted Pair (TP) is one of the most commonly used transmission media in integrated wiring engineering, and consists of two copper wires with an insulating protective layer. Two insulated copper wires are twisted together according to a certain density, and the electric wave radiated by each wire in transmission can be counteracted by the electric wave emitted by the other wire, thereby effectively reducing the degree of signal interference.
Twisted pairs are typically formed by intertwining two 22-26 insulated copper conductors, also known by the name "twisted pair". In practice, the twisted pairs are enclosed together in a single insulated cable jacket by a plurality of twisted pairs. Twisted pair cables are formed if one or more twisted pairs are placed in a single insulating sleeve, but "twisted pair cables" are generally referred to directly as "twisted pairs" in everyday life.
The twisted pair cable in the prior art is prone to low-temperature cracking, high-temperature deformation, fuzzy transmission signals, deterioration, hardening and the like under the conditions of poor environmental conditions such as low temperature, oil stain, acid-base corrosion and the like, and has crosstalk phenomenon due to the close distance between the cables, so that the bandwidth and the speed of the signals are affected.

To the problems of the prior art above, the utility model provides a novel shielding twisted pair cable.
The utility model discloses an adopt following technical scheme to realize:
the utility model provides a novel shielding twisted-pair cable, includes the cable core, the cable core includes a plurality of pairs of twisted-pair signal line, twisted-pair signal line comprises two conductor twists, the outer parcel of conductor has the insulating layer, and is every right the twisted-pair signal line outside has all wrapped up first shielding layer, it has a plurality of packing ropes to fill in the cable core, it has flame retardant fiber to fill in the rope clearance, the packing rope wraps up in proper order outward has interior sheath, second shielding layer, third shielding layer and oversheath.
The number of the twisted-pair signal wires is 2-4 pairs, and the twisting distance is 10-24 mm.
The first shielding layer adopts an aluminum-plastic composite film layer, the second shielding layer adopts an aluminum foil layer, and the third shielding layer adopts a metal grid shielding layer.
The insulating layer adopts a low-density polyethylene layer.
The inner sheath layer is a high-density polyethylene layer.
The outer sheath is a silicon rubber glass fiber layer.
The utility model has the advantages that:
1. the shielding effect is good, and the transmission stability is strong;
2. the structure is simple, the design is reasonable, and the use requirements of people are met;
3. high-temperature resistance, flame retardance, good chemical corrosion resistance and long service life.
