Background
The present world has entered the information age, and information has become a strategic resource and a unique production element of economic development, and a modern information transmission system and a complete information service system which are established by combining multimedia terminals such as telecommunication networks, computers, video and the like have become an important mark of the degree of economic development of a country or a region. The cable has the characteristics of internal electrification and external insulation, and the rigid coaxial cable is mainly used for communication lines and comprises four parts, namely a core wire, an insulator, a shielding layer and a sheath. When the cable is used, the cable not only needs to be bent or extruded, so that the cable is easy to break when in use, or the inner wire core is damaged, thereby influencing the normal use of the cable.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming the defect of prior art, the utility model aims at providing a waterproof special cable of high strength improves the compressive property of cable, can protect the inner core of cable simultaneously to improve the life and the result of use of cable.
Its solution is, waterproof special cable of high strength, including steel core, a plurality of cable inner cores, resistance water layer, fire-retardant layer, shielding layer, interior inoxidizing coating and outer inoxidizing coating, the inside of interior inoxidizing coating is equipped with hexagonal support frame, the support frame is inside to be fixed with six spinal branch vaulting poles, a plurality of spinal branch vaulting poles all with between the steel core fixed connection, six spinal branch vaulting poles are the cavity of six triangle-shaped with the internal partitioning of support frame, the inside columniform supporting shoe that all is equipped with of a plurality of cavitys, the supporting shoe respectively with adjacent two bracing pieces and support frame between tangent, the inside a plurality of cable inner cores that all is equipped with in clearance between supporting shoe and bracing piece and the support frame, the support frame outside is equipped with interior inoxidizing coating, the outside of interior inoxidizing coating is equipped with shielding layer, fire-retardant layer, water blocking layer and outer inoxidizing coating in proper order.
Preferably, the first filler is arranged in each of the plurality of cavities.
Preferably, a plurality of pressure reducing blocks fixed on the support frame are arranged between the support frame and the inner protective layer, and the plurality of pressure reducing blocks are all arc-shaped with openings facing the support frame.
Preferably, a second filler is arranged between the inner protective layer and the support frame.
The utility model has the advantages that: the compression resistance of the cable when in use can be improved, the service life of the cable is prolonged, and the stress of the cable core when being extruded is reduced, so that the damage of the cable core is reduced, and the service life of the cable is further prolonged.
Drawings
Fig. 1 is a schematic structural view of the whole front of the present invention.
Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
The high-strength waterproof special cable is characterized in that a hexagonal support frame 2 is arranged inside the inner protective layer 8, six support rods 3 are fixed inside the support frame 2, the support rods 3 are fixedly connected with the steel core 1, the six support rods 3 divide the inside of the support frame 2 into six triangular cavities, cylindrical support blocks 5 are arranged inside the cavities, the support blocks 5 are tangent to the two adjacent support rods 3 and the support frame 2 respectively, a plurality of cable cores 4 are arranged inside gaps between the support blocks 5 and the support rods 3 and the support frame 2, inner protective layers 8 are arranged outside the support frame 2, and the shielding layers 9 are sequentially arranged outside the inner protective layers 8, A flame retardant layer 10, a water barrier layer 11 and an outer protective layer 13.
This device is when using, at first place the position that needs work with this device, when the cable is by the extrusion, at first support frame 2 can support the cable, because 2 formation triangles of support frame of cable, further improvement the supporting effect of cable, when the cable further receives the extrusion, the extrusion force continues to carry out the application of force to the cable this moment, make support frame 2 produce and warp, on adding pressure and using supporting shoe 5 this moment, thereby make supporting shoe 5 unload the power to the extrusion force, reduce the damage to the cable core, the cable core all is located inside the clearance between supporting shoe 5 and the support frame 2, and then when making use, on avoiding using the cable core between the extrusion force, the atress of cable core has been reduced, further improvement the life and the compressive effect of cable. The inner protective layer, the shielding layer 9, the flame retardant layer 10, the water resistance layer 11 and the outer protective layer outside the cable body further protect the cable body.
The plurality of cavities are all internally provided with a first filler 12.
Through setting up first filler 12, can make the cable fill during the use, reduce the wearing and tearing of cable core.
A plurality of decompression blocks 6 fixed on the support frame 2 are arranged between the support frame 2 and the inner protective layer 8, and the plurality of decompression blocks 6 are all arc-shaped with openings facing the support frame 2.
Through setting up a plurality of arc decompression blocks 6, when the cable received the extrusion force during the use, at first a plurality of decompression blocks 6 produced and warp, absorbed the extrusion force, further improvement cable's compressive property.
And a second filler 7 is arranged between the inner protective layer 8 and the support frame 2.
By arranging the second filler 7, the degree of fullness of the cable is improved, and the using effect of the cable is further improved.
The utility model has the advantages that: the compression resistance of the cable when in use can be improved, the service life of the cable is prolonged, and the stress of the cable core when being extruded is reduced, so that the damage of the cable core is reduced, and the service life of the cable is further prolonged.
The above-mentioned embodiments are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design concept of the present invention should be included in the protection scope defined by the claims of the present invention.
