Description
Technical field
Field of cable technology is the utility model is related to, specially a kind of bus cable.
Background technology
Bus cable is mainly used between the field intelligent device in the fields such as process control, manufacture, building automatic
Interconnection communications network.It is using intelligent sensing, control, computer, the technology such as digital communication as main contents complex art,
Field bus device is in the bottom of process device, is shop equipment level underlying communication network, and it has agreement simple, fault-tolerant
The features such as ability is strong, security is good, and there is preferable time determinability and higher real-time.The cable performs at present
International standard IEC61158.2, the country is without bus cable standard.This kind of cable in actual use, based on level
The equipment of communication, its shielding properties is poor, under the electromagnetic environment of complexity, is easily interfered, influences the communication quality of equipment.
Utility model content
The utility model purpose is to provide a kind of bus cable, possesses excellent electromagnetism interference performance, ensures to set
Standby communication quality.
To achieve these goals, the technical solution adopted in the utility model is：A kind of bus cable, including core
Conductor, the insulating barrier of cable core conductor outer cladding first and the second insulating barrier form master core, two master cores pair twist structure
Into cable core, internal shield, external shielding layer and oversheath are coated with successively outside the cable core.
Compared with prior art, technique effect of the present utility model is：Internal shield and external shielding layer are set outside cable core, this
Sample makes cable obtain dual shielding protection, prevents the electromagnetic environment interference of extraneous complexity, plays a part of shielding external electric field, make
Cable possesses excellent electromagnetism interference performance, ensures the communication quality of connection equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the utility model is described in further detail.
A kind of bus cable, it is characterised in that：Including cable core conductor 1, the outer cladding of cable core conductor 1 first insulate
The insulating barrier 3 of layer 2 and second forms master core, and two master core pair twists form cable core, are coated with successively outside the cable core interior
Screen layer 4, external shielding layer 5 and oversheath 6.
Main line core conductor 1 can use a kind of copper conductor, set internal shield 4 and external shielding layer 5 outside cable core, so make electricity
Cable obtains dual shielding protection, prevents the electromagnetic environment interference of extraneous complexity, plays a part of shielding external electric field, have cable
Standby excellent electromagnetism interference performance, ensure the communication quality of connection equipment.
Second insulating barrier 3 is to extrude the solid double-layer polyethylene of foaming on the first insulating barrier 2 to form, and so has cable
There are excellent electric property and mechanical performance.
The internal shield 4 is the tinned copper wire woven on cable core.
The external shielding layer 5 is aluminium-plastic tape wrapped on internal shield 4.
Such scheme is the preferred scheme of internal shield 4 and external shielding layer 5, i.e., is moulded after first weaving tinned copper wire further around alclad
Composite band forms the dual shield protection of cable.
The oversheath 6 is low-smoke and halogen-free flame retardant polyolefin jacket, and this kind of sheath is environment friendly and pollution-free, leads to suitable for base level
The equipment of letter.
