Description
Technical field
This utility model relates to a kind of rat-and-ant proof low smoke zero halogen computer cable, belongs to industrial cable field.
Background technology
Automated condtrol is popularized in a large number, and computer is the core that signal controls, and computer cable to be computer important
Connecting element.But computer cable is susceptible to such as fire, Mus ant some personnel compared with the place concentrated, atmospheric density is low to be gnawed
Sting etc. unexpected, and traditional flame retardant cable typically uses polrvinyl chloride as sheath, although pvc material has anti-flammability
The features such as good, inexpensive, expressing technique is good, but contain halogen due to it, a large amount of hydrogen halide and dense smoke can be released during burning, make
Become " the secondary harm " of fire, thus increase the loss of fire.Especially a lot of scientific researches are it has proven convenient that halogenide is to human body
The infringement that health and environment is caused is the most serious.So once breaking out of fire or Mus ant destroy cable, will directly jeopardize
The transmission of signal and the safety of personnel, the performance of these class area computer cables of the most necessary raising.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of rat-and-ant proof low smoke zero halogen computer cable, and this is prevented
Mus ant low smoke zero halogen computer cable safety and environmental protection, is hardly damaged, advantages of good shielding performance, good flame resistance, it is possible to effectively take precautions against Mus ant
Bite cable.
The technical solution of the utility model is as follows:
A kind of rat-and-ant proof low smoke zero halogen computer cable, including multi-cable inner core with around wrapping in outside multi-cable inner core
Cable outer layer；Described cable inner core includes conductor, be coated on outside conductor interior halogen-free resin composition insulating barrier and being coated on
Outer halogen-free fire-proof resin composition insulating barrier outside interior halogen-free resin composition insulating barrier；Described cable outer layer includes metal knitted
Layer, the polypropylene layer that is coated on outside wire sheathing and be sprayed on the rat-and-ant proof medicine layer outside polypropylene layer；Described outer Halogen
Fire-proof resin composition insulating barrier outer surface is provided with multiple double wedge along the even circumferential in cross section, and adjacent cable inner core is by convex
Tooth engages each other；Described polypropylene layer outer surface is uneven.
Wherein, described interior halogen-free resin composition insulating barrier with the thickness ratio of outer halogen-free fire-proof resin composition insulating barrier is
1:1。
This utility model has the advantages that
1, this utility model safety and environmental protection, is hardly damaged, advantages of good shielding performance, good flame resistance, and interior halogen-free resin composition is exhausted
When edge layer and the burning of outer halogen-free fire-proof resin composition insulating barrier, low cigarette is pollution-free；The insulation of interior halogen-free resin composition insulating barrier
Property is good, the good flame resistance of outer halogen-free fire-proof resin composition insulating barrier；Polypropylene layer hardness and toughness are strong, prevent to a certain extent
Mus ant bites；Polypropylene layer and rat-and-ant proof medicine layer are collectively forming the Double-protection to Mus ant.
2, this utility model polypropylene layer outer surface is uneven, and the dose that rat-and-ant proof medicine can be made to spray is bigger and anti-
Mus ant medicine layer is not easy to come off.
3, the cable inner core that this utility model is adjacent is engaged each other by double wedge, makes to fit between multi-cable inner core tighter
Close, be difficult to slide.
4, this utility model simple in construction, reasonable in design, practical.
Accompanying drawing explanation
Fig. 1 is a kind of rat-and-ant proof low smoke zero halogen computer cable structural representation of the present utility model.
In figure, reference is expressed as:
Halogen-free resin composition insulating barrier, the outer halogen-free fire-proof resin composition of 13-in 1-cable inner core, 11-conductor, 12-
Insulating barrier, 131-double wedge, 2-cable outer layer, 21-wire sheathing, 22-polypropylene layer, 23-rat-and-ant proof medicine layer.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Seeing Fig. 1, a kind of rat-and-ant proof low smoke zero halogen computer cable, including multi-cable inner core 1 with around wrapping in many electricity
