Abstract
The utility model discloses a prevent rifle and hit communication cable, establish the intraformational band layer of aluminium strip, aluminium strip including outer jacket, cover and establish a plurality of wires in the band layer of outer jacket to and locate the intraformational band, the wire includes insulating layer and the intraformational conductor of insulating, still be equipped with steel strip layer and interior sheath from the extroversion in proper order between outer jacket and the aluminium strip layer. The communication cable is provided with the inner protective layer and the outer protective layer, and the steel belt layer is clamped between the inner protective layer and the outer protective layer, so that the communication cable is excellent in mechanical performance, can prevent or reduce gunshot damage, and guarantees the communication safety in a fire fighting area.
Description
Technical field
The utility model relates to a kind of anti-gunshot communication cable.
Background technology
As the effective means of big capacity, long Distance Transmission, cable and optical cable are by a large amount of application.Traditional broadband cable comprises oversheath, and the twining package tape in the oversheath is provided with some cables in the twining package tape, and every cable comprises that again lead and lead are provided with insulating barrier outward.Yet, jungle rare at some field operations, population and be in area in the flames of war, common telecommunication cable probably suffers flames of war infringement and telecommunication cable is damaged, and causes the communication efficiency variation even interrupts fully.Yet message transmission unimpeded is almost that current social all trades and professions are required, and it is interfered or interrupts, and will bring the loss that can't estimate, therefore need use in these areas mechanical performance strong, be difficult for telecommunication cable as the bullet damage.
Summary of the invention
The utility model purpose provides a kind of anti-gunshot communication cable, and it is provided with inside and outside sheath, and is folded with steel belt layer between inside and outside sheath, makes that the telecommunication cable mechanical performance is good, can prevent or reduce gunslinging and damage.
The technical solution of the utility model is: a kind of anti-gunshot communication cable, comprise outer jacket, be set in the aluminium strip layer in the outer jacket, the belting layer in the aluminium strip layer, and be located at some leads in the belting layer, described lead comprises the conductor in insulating barrier and the insulating barrier, also is provided with steel belt layer and sheath between described outer jacket and the aluminium strip layer from outside to inside successively.
The further technical scheme of the utility model is: a kind of anti-gunshot communication cable, comprise outer jacket, be set in the aluminium strip layer in the outer jacket, the belting layer in the aluminium strip layer, and be located at some leads in the belting layer, described lead comprises the conductor in insulating barrier and the insulating barrier, also is provided with steel belt layer and sheath between described outer jacket and the aluminium strip layer from outside to inside successively; Described steel belt layer is electroplated the wrinkle composite steel-plastic belt for the vertical bilayer that is wrapped on the sheath.
The utility model advantage is:
1. the utility model is provided with inside and outside two-layer sheath, and is folded with steel belt layer between inside and outside sheath, makes that the telecommunication cable mechanical performance is good, can prevent or reduce gunslinging and damage.
2. the aluminium strip layer plays shielding action in the utility model, when the frequency of interfere with electromagnetic field is higher, utilizes the eddy current that produces in the metal material of low-resistivity, forms externally to come electromagnetic negative function, thereby reaches the effect of shielding; It can effectively reduce electromagnetic interference, prevent information leakage.
3. belting layer of the present utility model had both played the effect of guard shield layer, strengthened stability of structure again, and this helped the uniform and stable of impedance, had improved the transmission performance of cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 outer jacket; 2 steel belt layers; 3 sheaths; 4 aluminium strip layers; 5 belting layers; 6 insulating barriers; 7 conductors.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1, a kind of anti-gunshot communication cable, comprise outer jacket 1, be set in the aluminium strip layer 4 in the outer jacket 1, the belting layer 5 in the aluminium strip layer 4, and be located at some leads in the belting layer 5, described lead comprises the conductor 7 in insulating barrier 6 and the insulating barrier 6, also is provided with steel belt layer 2 and sheath 3 between described outer jacket 1 and the aluminium strip layer 4 from outside to inside successively.
Wherein: steel belt layer 2 is electroplated the wrinkle composite steel-plastic belt for the vertical bilayer that is wrapped on the sheath 3; 4 shielding action of aluminium strip layer when the frequency of interfere with electromagnetic field is higher, utilize the eddy current that produces in the metal material of low-resistivity, form externally to come electromagnetic negative function, thereby reach the effect of shielding; It can effectively reduce electromagnetic interference, prevent information leakage; Belting layer 5 had both played the effect of guard shield layer, strengthened stability of structure again, and this helped the uniform and stable of impedance, had improved the transmission performance of cable.
The utility model is provided with inside and outside two-layer sheath, and is folded with steel belt layer between inside and outside sheath, makes that the telecommunication cable mechanical performance is good, can prevent or reduce gunslinging and damage.
