Description
Technical Field
The utility model relates to a cable technical field especially relates to binary channels ultra-long distance low attenuation light signal control cable.
Background
The light signal control line is specially designed for controlling data communication between the stage lighting control console and the light modulator, and because the light signal control line can make numerous light modulators used by the stage compatible with the controller, the light signal control line has strong practicability and is widely adopted by the entertainment industry. However, the existing light signal control cannot meet the requirement of ultra-long distance use, and therefore, an ultra-long distance low-attenuation light signal control cable needs to be designed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a binary channels ultra-long distance low attenuation light signal control cable effectively realizes ultra-long distance transmission signal.
The technical scheme for realizing the purpose is as follows:
a dual channel ultra-long distance low attenuation light signal control cable comprising:
an outer sheath;
the inner sheath is positioned in the inner cavity of the outer sheath and clings to the inner wall of the outer sheath;
the two aluminum foil shielding layers are arranged in the inner cavity of the inner sheath;
two conductors disposed within each of the aluminum foil shielding layers;
an insulating layer covering each of the conductors; and
and the ground wire is arranged in each aluminum foil shielding layer.
Preferably, two of the conductors covering the respective corresponding insulating layers are twisted with each other.
Preferably, the outer sheath is made of polyvinyl chloride material; the insulating layer adopts a polyethylene sheath insulating sleeve.
Preferably, the conductor is a tin-plated compacted stranded conductor.
Preferably, the aluminum foil shielding layer and the inner sheath are filled with a plurality of filling strips.
The utility model has the advantages that: the utility model discloses an effectual structural design, especially the design of shielding layer has increased the interference killing feature of cable greatly, makes the electrical property more excellent, more is fit for long distance engineering and uses. Meanwhile, the effect of transmitting signals in an ultra-long distance is further realized through the chemical high-foaming polyethylene and the conductor pressing structure.
Drawings
Fig. 1 is the structure diagram of the dual-channel ultra-long distance low attenuation light signal control cable of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the dual-channel ultra-long-distance low-attenuation light signal control cable of the present invention includes an outer sheath 1, an inner sheath 2, two aluminum foil shielding layers 3, four conductors 4, four insulating layers 5, and two ground wires 6.
The inner sheath 2 is positioned in the inner cavity of the outer sheath 1 and clings to the inner wall of the outer sheath 1. The aluminum foil shielding layer 3 is arranged in the inner cavity of the inner sheath 2. Every two conductors 4 are arranged in each aluminium foil shield 3. Each conductor 4 is covered with an insulating layer 5. A ground wire 6 is arranged in each aluminium foil shield 3. Aluminium foil shielding layer 3 can increase the utility model discloses the shielding effect that has good low frequency range. In the aluminium foil shielding layer 3, the cladding corresponds two conductors 4 of insulating layer 5 each other and twists, makes the utility model discloses it is more durable.
The outer sheath 1 is made of polyvinyl chloride material. The insulating layer 5 adopts a high-chemical high-foaming polyethylene leather-covered insulating sleeve. The conductor 4 is a tinned compacted stranded conductor. The aluminum foil shielding layer 3 and the inner sheath 2 are filled with a plurality of filling strips, so that the toughness and the pressure resistance of the cable can be improved, and the service life of the cable is prolonged.
To sum up, the utility model discloses an effect of extra long distance transmission signal.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
