Description
Technical field
The present invention relates to field of cable technology, more particularly to a kind of highly effective flame-retardant formula composite cable.
Background technology
With developing rapidly for China's economy, cable plays pole as the main media of modern communication in all trades and professions
Its important effect, so the barrier propterty of cable is more and more paid attention to.But the fire-retardant and fire prevention of cable at present
Performance is not good, especially under some emergency cases, it is easy to the situation for making existing cable be damaged.
The content of the invention
The invention aims to the fire-retardant and fire protecting performance for solving cable present in prior art it is not good lack
Point, and a kind of highly effective flame-retardant formula composite cable proposed.
To achieve these goals, present invention employs following technical scheme：
Design in a kind of highly effective flame-retardant formula composite cable, including the first sheath, first sheath and be provided with multiple cable cores,
The outside of each cable core, which is provided with protective case, first sheath, is provided with two orthogonal separations
Plate, the inwall of the two ends of two demarcation strips respectively with the first sheath is fixedly connected, and two demarcation strips are by the first sheath
Inner space even partition is placed with cable core, the cable core into four placement spaces, and in each placement space
Exotic material is filled between line and demarcation strip；
Offered in first sheath along its circumference and mineral matter fire material be filled with annular filling slot, the filling slot,
And multiple supporting plates are also arranged at intervals with filling slot, the supporting plate contacts setting, institute with the two side of filling slot respectively
The outside for stating the first sheath is provided with the second sheath, the lateral wall of first sheath and is arranged at intervals with multiple link slots, and
Be arranged at intervals with the inserted block of connection corresponding with multiple link slots on the inwall of second sheath, first sheath and the second sheath it
Between space in be filled with fiberglass braided thing.
It is preferred that, the exotic material is set to silicon rubber.
It is preferred that, the supporting plate is set to curved support plate.
It is preferred that, the length of the inserted block is more than the depth of link slot.
A kind of highly effective flame-retardant formula composite cable proposed by the present invention, beneficial effect is：It is arranged on inside the first sheath
The mineral matter fire material of filling, the glass being arranged between the first sheath and the second sheath in exotic material and filling slot
Fibrous braid is respectively provided with preferable fire-retardant and fireproof effect, can be prevented effectively from when cable meets fire or high temperature and be easily damaged
Situation, and be arranged on the demarcation strip inside the first sheath and the supporting plate being arranged in filling slot and can improve cable
Bulk strength, is more convenient for actually used.
Brief description of the drawings
Fig. 1 is a kind of structural representation of highly effective flame-retardant formula composite cable proposed by the present invention.
In figure：First sheath 1, mineral matter fire material 2, filling slot 3, link slot 4, fiberglass braided thing 5, supporting plate
6th, protective case 7, cable core 8, demarcation strip 9, the second sheath 10, inserted block 11, exotic material 12.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.
Multiple electricity are provided with reference picture 1, a kind of highly effective flame-retardant formula composite cable, including the first sheath 1, the first sheath 1
Core 8, the outside of each cable core 8, which is provided with protective case 7, the first sheath 1, is provided with two orthogonal point
Dividing plate 9, the inwall of the two ends of two demarcation strips 9 respectively with the first sheath 1 is fixedly connected, and two demarcation strips 9 are by the first sheath 1
Inner space even partition into four placement spaces, it is by two demarcation strips 9 that multiple cable cores 8 are separated, can drop
The power that influences each other between low multiple cable cores 8, it is to avoid can be to remaining electricity when one of cable core 8 is damaged
Cable core 8 is placed with the situation that the use of core 8 is impacted, and each placement space, cable core 8 is with dividing
Exotic material 12 is filled between dividing plate 9, exotic material 12 is set to silicon rubber, silicon rubber have preferable high temperature resistant with
And flame retardant effect, it is possible to increase the overall fire resistance of cable.
Offered in first sheath 1 along its circumference and mineral matter fire material 2 be filled with annular filling slot 3, filling slot 3,
And multiple supporting plates 6 are also arranged at intervals with filling slot 3, supporting plate 6 contacts setting with the two side of filling slot 3 respectively, propped up
Fagging 6 is set to curved support plate, and curved support plate has preferable compressive property, can ensure that it is preferably anti-that cable has
Also there is higher intensity while fiery performance.
The outside of first sheath 1 is provided with the second sheath 10, the lateral wall of the first sheath 1 and is arranged at intervals with multiple connections
The inserted block 11 of connection corresponding with multiple link slots 4, the length of inserted block 11 are arranged at intervals with groove 4, and the inwall of the second sheath 10
More than the depth of link slot 4, so set and can ensure that there is space between the first sheath 1 and the second sheath 10, be easy to glass fibers
Tie up and fiberglass braided thing 5 is filled with the filling of braid 5, the space between the first sheath 1 and the second sheath 10.
Operation principle：In the exotic material 12 and filling slot 3 that are arranged on inside the first sheath 1 mineral matter of filling every
