Description
Technical field
It the utility model is related to field of cable technology, more particularly to a kind of high-strength fire-retardant cable.
Background technology
At present, people are to fast transfer of data, the needs of information, to computer, word processor, fax, sensor and
The dependence of communication equipment significantly rapidly increases.The appearance of new technology make it that online turn into networking of the equipment of this respect can
Can, it result in the comprehensive development of communication system.These systems increase in the use of specific area, such as skyscraper, ship, fly
Machine, train, drilling platforms and mine.In order to connect these electronic components, it is necessary to using a large amount of in these structures and field
Electric wire and cable.
Cable can be frequently by punching press and torsion during use is laid, and long-term to pull, it is easy that fracture easily occurs for core
Cause the fracture of core, core once disconnected core, and cause equipment to stop operating, have a strong impact on normal production operation, and cable
Fire protecting performance it is relatively low, security is difficult to ensure that.
Utility model content
The purpose of this utility model is that intensity is relatively low present in prior art and what fire resistance was poor lacks in order to solve
Point, and a kind of high-strength fire-retardant cable proposed.
To achieve these goals, the utility model employs following technical scheme：
A kind of high-strength fire-retardant cable, including the first sheath are designed, is provided with multiple conductors in first sheath, each
The outside of conductor is disposed with insulation sleeve, metallic sheath and separation sleeve, and four arcs are arranged at intervals with first sheath
Shape supporting plate, and multiple conductors are evenly distributed in four curved support plates, the space between conductor and the curved support plate
Place is filled with oxygen barrier material, and mineral matter fire material is filled with the outer gap of four curved support plates, and described the
Support bar is additionally provided with one sheath, the support bar is between four curved support plates；
The outside of first sheath is also arranged with the second sheath, and gold is provided between first sheath and the second sheath
Belong to bar and glass cord, and bonding jumper is twist wrapped in the outside of the first sheath, the metal with glass cord
Bar and glass cord are interlaced setting.
Preferably, the outside of the support bar is provided with support set.
Preferably, the outside of the support bar contacts setting with four curved support plates respectively.
The utility model proposes a kind of high-strength fire-retardant cable, beneficial effect is：Four curved support plates will be multiple
Conductor even partition is not only acted on preferable flameproof protection, cable is integrally had higher intensity into the quartering,
And the support effect of curved support plate can also be increased by being arranged on the support bar between four curved support plates, effectively increase electricity
The intensity of cable, it is easy to actually use；Bonding jumper of the Stagger-wrap outside the first sheath not only has preferable with glass cord
Flameproof effect, and also increase the intensity of cable.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of high-strength fire-retardant cable sectional view；
Fig. 2 be the utility model proposes a kind of high-strength fire-retardant cable the first sheath external structure schematic diagram.
In figure：First sheath 1, bonding jumper 2, the second sheath 3, curved support plate 4, conductor 5, separation sleeve 6, metallic sheath 7, absolutely
Edge set 8, oxygen barrier material 9, support set 10, support bar 11, mineral matter fire material 12, glass cord 13.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of high-strength fire-retardant cable, including the first sheath 1, multiple conductors are provided with the first sheath 1
5, the outside of each conductor 5 is disposed with insulation sleeve 8, metallic sheath 7 and separation sleeve 6, is arranged at intervals with the first sheath 1
Four curved support plates 4, arcuate structure is designed to by supporting plate, can improve the resistance to pressure of supporting plate, and multiple conductors 5 uniformly divide
For cloth in four curved support plates 4, the gap between conductor 5 and curved support plate 4 is filled with oxygen barrier material 9, and four arcs
Mineral matter fire material 12 is filled with the outer gap of shape supporting plate 4, support bar 11 is additionally provided with the first sheath 1, is supported
Bar 11 is between four curved support plates 4, and the outside of support bar 11 contacts setting with four curved support plates 4 respectively, so
The integrated support intensity of support bar 11 and curved support plate 4 can be increased by setting, and the outside of support bar 11 is provided with support set 10, be propped up
Support set 10 has preferable protective effect to support bar 11.
The outside of first sheath 1 is also arranged with the second sheath 3, and bonding jumper is provided between the first sheath 1 and the second sheath 3
2 with glass cord 13, and bonding jumper 2 and glass cord 13 are twist wrapped in the outside of the first sheath 1, bonding jumper
2 and glass cord 13 are interlaced setting, and the overall intensity of cable can both have been improved by so setting, and can also improve cable
Fire protecting performance.
Operation principle：Four curved support plates 4 into the quartering, not only have multiple even partitions of conductor 5 preferably anti-
Fiery protective effect, it can also make cable that integrally there is higher intensity, and the support bar being arranged between four curved support plates 4
11 can also increase the support effect of curved support plate 4；Bonding jumper 2 and glass cord of the Stagger-wrap outside the first sheath 1
13 can also increase the intensity of cable while with preferable flameproof effect.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
