Abstract
The utility model discloses a resistance to compression fire-retardant type cable, including first support piece and second support piece, four salient angles that first support piece and second support piece distribute in opposite directions are equipped with the first arc recess and the second arc recess that match each other respectively, and the parcel has the heart yearn between first arc recess and the second arc recess, and it has fire-retardant layer to fill between first support piece and the second support piece, and second support piece outside parcel is equipped with the resistance to compression elastic layer. The utility model provides a resistance to compression fire-retardant type cable, the outside atress of cable is even, has strengthened the compressive property of cable, and simultaneously, the flame retardant efficiency of cable is good, has prolonged the life of cable.
Description
Technical Field
The utility model belongs to the cable field, concretely relates to resistance to compression fire type cable.
Background
A cable is a rope-like cable made up of several twisted sets of conductors, each set insulated from the other and often twisted around a center, the entire outer surface being covered with a highly insulating covering.
In the processing process of the cable with a plurality of wires, each wire is mutually wound or coated in the coating layer according to certain arrangement, and then different coating layers are adopted for carrying out multilayer coating according to the use requirement. However, the cable is not positioned between the inner leads, so that the cable is easily twisted in the coating process, the core wires inside the cable are easily dislocated in the process of receiving external force, the external force is not uniform, the cable is further greatly damaged, the transmission power of the cable is reduced, the fireproof effect of the existing cable is poor, and the cable is seriously damaged once burning occurs.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a resistance to compression fire-retardant type cable, the outside atress of cable is even, has strengthened the compressive property of cable, and simultaneously, the flame retardant efficiency of cable is good, has prolonged the life of cable.
The utility model discloses a realize through following technical scheme: the utility model provides a fire-retardant type cable of resistance to compression, includes first support piece and second support piece, four salient angles that first support piece and second support piece distribute in opposite directions are equipped with the first arc recess and the second arc recess that match each other respectively, the parcel has the heart yearn between first arc recess and the second arc recess, it has fire-retardant layer to fill between first support piece and the second support piece, second support piece outside parcel is equipped with the elastic layer of resistance to compression.
And elastic layers are padded in the first arc-shaped groove and the second arc-shaped groove.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model has novel structure, the core wire inside the cable is supported by two supporting pieces, and the core wire can be positioned with high strength, so that the core wire is not easy to be distorted in the process of outer coating, the external stress of the cable is uniform, and the compression resistance of the cable is enhanced; the core wire is supported by the supporting piece, so that the compression strength of the core wire is improved, and the core wire in the cable is prevented from being damaged when the cable is compressed; the elastic layer is arranged in the arc-shaped groove of the convex angle of the supporting piece in a cushioning mode, so that the influence of external pressure on the core wire can be further weakened, the core wire can be protected in a cushioning mode, and the service life of the cable is prolonged; the flame-retardant layer is filled between the supporting pieces, so that the cable can be insulated and flame-retardant, and the flame-retardant performance of the cable is further enhanced; the outer layer is a compression-resistant elastic layer, so that the compression resistance of the cable can be improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the drawings: 1. a first support member; 2. a second support member; 3. a first arc-shaped groove; 4. a second arc-shaped groove; 5. a core wire; 6. a flame retardant layer; 7. a compression resistant resilient layer.
Detailed Description
As shown in fig. 1 in the drawings of the specification, a compression-resistant flame-retardant cable comprises a first supporting member 1 and a second supporting member 2, four convex angles of the first supporting member 1 and the second supporting member 2 which are distributed oppositely are respectively provided with a first arc-shaped groove 3 and a second arc-shaped groove 4 which are matched with each other, a core wire 5 is wrapped between the first arc-shaped groove 3 and the second arc-shaped groove 4, and the core wire 5 can be positioned at high strength, so that the core wire 5 is not easily distorted in the outer coating process, the external stress of the cable is uniform, the compression resistance of the cable is enhanced, the compression-resistant strength of the core wire 5 is improved, the phenomenon that the inner core wire 5 is damaged when the cable is compressed is avoided, a flame-retardant layer 6 is filled between the first supporting member 1 and the second supporting member 2, the cable is heat-insulating flame-retardant, and further the flame-retardant performance of the.
The cushion is equipped with the elastic layer in first arc recess 3 and second arc recess 4, can further weaken the influence of external pressure to heart yearn 5, can play the effect of buffer protection to heart yearn 5, improves the life of cable.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
