Abstract
The utility model discloses the shielded cables that earth lead is had in a kind of conductor; it is characterized in that; including conductor, insulating layer, band separation layer, shielded layer and the protective case set gradually from inside to outside; the center of the conductor is equipped with an earth lead, and the earth lead includes the inner conductor set gradually from inside to outside, inner insulating layer and interior band separation layer.The utility model realizes the function that short circuit will not occur when shielded layer passes through high current due to being equipped with an earth lead ground structure at the center of conductor.
Description
Technical field
The utility model relates to field of cable technology, and in particular to the shielded cable of earth lead is had in a kind of conductor.
Background technique
The shielded layer of common cable generally uses one layer of metal compound belt that a piece-root grafting ground wire is added to be made, the cable system of the structure
Simple process and low cost is made, but is unable to satisfy the demand for much needing explosion-proof industry.And cable is in use,
Shielded layer is easy to happen short circuit phenomenon.
Utility model content
The purpose of this utility model is to provide the shielded cables that earth lead is had in a kind of conductor, solve common cable
Shielded layer is easy to happen the technical issues of short circuit phenomenon.
The technical issues of the utility model is solved can be realized using following technical scheme：
The shielded cable that earth lead is had in a kind of conductor, including the conductor, insulating layer, packet set gradually from inside to outside
Band separation layer, shielded layer and protective case, the center of the conductor are equipped with an earth lead, and the earth lead includes from inside to outside
Inner conductor, inner insulating layer and the interior band separation layer set gradually.
The shielded layer is soft copper band shielded layer.
The protective case is the protective layer made of Ceramic silicon rubber material.
Ceramic silicon rubber material at normal temperature it have the good fundamental characteristics of silicon rubber elastic, have it is nontoxic, tasteless,
High-low temperature resistant, ozone and aging resistance, weatherable, excellent electrical insulation capability, also have common high temperature silicone rubber it is good plus
Work performance is able to maintain flexible cable state to 200 degree above freezing or so in 40 degrees below zero.It is invaded in flame, temperature is up to 300 degree or more
When, the sponge ceramic body of hardness can be converted to by original soft condition, generate hole after being hardened inside fireproof jointing sheath, favorably
In heat preservation, such sponge ceramic body has the function of significant fire resisting and barrier high temperature, so that the inside of cable be effectively protected
Machinery change and electrical property variation do not occur for structure.
Beneficial effect：The utility model is realized due to being equipped with an earth lead ground structure at the center of outer conductor
The function of short circuit will not occur when passing through high current for shielded layer.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig.1, the shielded cable of earth lead is had in the conductor of the utility model, including is set gradually from inside to outside
Conductor 4, insulating layer 5, band separation layer 6, soft copper band shielded layer 7 and protective case 8, the center of the conductor is equipped with a ground connection and leads
Line, the earth lead include the inner conductor 1 set gradually from inside to outside, inner insulating layer 2 and interior band separation layer 3.
The protective case 8 is the protective layer made of Ceramic silicon rubber material.Ceramic silicon rubber material is at normal temperature
It has the good fundamental characteristics of silicon rubber elastic, has nontoxic, tasteless, high-low temperature resistant, ozone and aging resistance, weatherable, excellent
Good electrical insulation capability also has the good processing performance of common high temperature silicone rubber, in 40 degrees below zero to 200 degree above freezing or so
It is able to maintain flexible cable state.When flame is invaded, and temperature is up to 300 degree or more, can be converted to by original soft condition rigid
Sponge ceramic body generates hole, is conducive to keep the temperature inside fireproof jointing sheath after being hardened, such sponge ceramic body has significant resistance to
The effect of fire and barrier high temperature, so that machinery change and electrical property variation do not occur for the internal structure that cable is effectively protected.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
