Description
Technical field
The utility model is related to a kind of cab signal cable of commercial car.
Background technology
Existing signal cable is a kind of signal transmission instrument.The signal very little of general signal cable transmission, in order to avoid
Signal is interfered, and there is one layer of screen layer signal cable outside, and the screen layer of the conductor of parcel, generally conductive fabric weave copper
Net or copper pool (aluminium), screen layer need ground connection, and external interference signal can import the earth by the layer, it is to avoid in interference signal enters
The interference of layer conductor reduces the loss of transmission signal simultaneously.Sensor signal cable is used for various sensors, the signal of instrument and meter
Transmission.Sensor signal cable is using plating silver conductor, multicore structure, it is ensured that keep highly consistent per resistance between core, can be by
Faint electric quantity signal accurate delivery is to outside hundreds of meters.Sensor signal cable problem is using tin plating or plating silver conductor.Sensor
Signal cable possesses four layers of protection, respectively insulating barrier, screen layer, winding layer, restrictive coating, is only to ensure faint electric quantity signal
Accurate delivery.Insulating barrier:The process based prediction model suitable with restrictive coating, can reject sheath, shielding in narrow and small environment
Net and winding layer, individually use as wire.Winding layer:Winding layer is a kind of selected polymeric material, mainly prevents screen
Cover net and injure insulating barrier.Also the overall mechanical performance of cable is strengthened.Screen layer:Fastidious metal material (using copper or tin-coated copper)
On the one hand interference signal is successfully derived, superfine wire there must be enough bend resistance abilities to avoid metal fragment shadow
Ring other electrical equipments.Restrictive coating:Excellent mechanical performance, is resistant to metal strike, the cutting of higher-strength.With very
Tensile strength high, also can tolerate long-term repetition bending.
Current existing commercial car signal cable does not have tension and resistance to compression effect, while not having heat insulation function.
Utility model content
The technical problems to be solved in the utility model is to provide one kind has tension and resistance to compression effect, while having insulation work(
The cab signal cable of the commercial car of energy.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of cab signal cable of commercial car, including optical fiber, nylon sleeve and polyvinyl chloride layer, the optical fiber are located at Buddhist nun
In actor playing a supporting role's pipe, the rectangular setting of nylon sleeve, nylon sleeve middle part both sides are provided with the groove to bending, the groove
Setting triangular in shape, is also filled with aerosil layer in the nylon sleeve, the polyvinyl chloride layer and nylon sleeve it
Between be filled with layer of polystyrene foam, polyvinyl chloride layer outside is provided with polyethylene layer, glass layer and engineering plastics
Pipe, the polyethylene layer both sides have been symmetrical set polypropylene rope.
Preferably, the polyethylene layer, glass layer and engineering plastics pipe are set from the inside to the outside successively, glass fibre
Layer and engineering plastics pipe being capable of lift structure intensity.
Preferably, the optical fiber is provided with four, optical fiber uses the fiber being made up of glass or plastics.
Preferably, the polyvinyl chloride layer thickness is 2mm, insulation effect is good.
Preferably, the nylon sleeve thickness is 1.5mm, optical fiber can be loosely placed, protect optical fiber from inside
Stress and outer side pressure influence.
Preferably, a diameter of 2.5mm of polypropylene rope, lifts the tensile strength of cable.
The beneficial effects of the utility model are：The polypropylene rope of setting causes that cable has tension effect；The engineering plastic of setting
Expects pipe can lift structure intensity, optical fiber can be loosely placed in nylon sleeve, protect optical fiber from internal stress with it is outside
Lateral pressure influences, and with resistance to compression effect, the layer of polystyrene foam of setting has heat insulation function, can be normal under low-temperature condition
Use.
Brief description of the drawings
Fig. 1 is a kind of profile of the cab signal cable of commercial car of the utility model.
Specific embodiment
As shown in figure 1, a kind of cab signal cable of commercial car, including optical fiber 1, nylon sleeve 2 and polyvinyl chloride layer 3,
The optical fiber 1 is located in nylon sleeve 2, the rectangular setting of the nylon sleeve 2, the middle part both sides of the nylon sleeve 2 be provided with to
The groove 4 of bending, groove 4 can deform after causing the stress of nylon sleeve 2, protect optical fiber 1 from internal stress and outside side pressure
Power influences.Aerosil layer 5, gas phase dioxy are also filled with the setting triangular in shape of the groove 4, the nylon sleeve 2
SiClx layer 5 has moisture effect, can reach the effect of fine cream.Filled with poly- between the polyvinyl chloride layer 3 and nylon sleeve 2
Styrene bubbles foam layer 6, the outside of the polyvinyl chloride layer 3 is provided with polyethylene layer 7, glass layer 8 and engineering plastics pipe 9, institute
State the both sides of polyethylene layer 7 and be symmetrical set polypropylene rope 10.The polyethylene layer 7, glass layer 8 and engineering plastics pipe 9 according to
It is secondary to set from the inside to the outside.The optical fiber 1 is provided with four.The thickness of the polyvinyl chloride layer 7 is 2mm.The thickness of the nylon sleeve 2 is
1.5mm.The a diameter of 2.5mm of the polypropylene rope 10.
The beneficial effects of the utility model are：The polypropylene rope of setting causes that cable has tension effect；The engineering plastic of setting
Expects pipe can lift structure intensity, optical fiber can be loosely placed in nylon sleeve, protect optical fiber from internal stress with it is outside
Lateral pressure influences, and with resistance to compression effect, the layer of polystyrene foam of setting has heat insulation function, can be normal under low-temperature condition
Use.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
