The making of the optoelectrical cable of gasket for packing.
Special-shaped packing gasket in the present invention has that simple in construction, easily makings, humidity, processing characteristics be excellent, resistance to compression recovery
Function admirable, excellent, acid and alkali-resistance ageing-resistant, elastic and the beneficial effect such as oil, low water suction.
The optoelectrical cable with special-shaped packing gasket in the present invention, owing to having used above-mentioned special-shaped packing gasket, abnormal shape is filled out
Fill the circle corresponding not less than this arc of the arc length of the 3rd cylinder arc body in rope circumference 2/3 and the 3rd cylinder arc body arc length not
The 4/5 of the circumference of the circle corresponding more than this arc, therefore, fiber optic communication unit is predominantly located in the 3rd cylinder arc body, has one
Part is positioned at outside the 3rd cylinder arc body, owing to special-shaped packing gasket has excellent elasticity and toughness, therefore, fiber optic communication unit
Can be made as the 3rd cylinder arc body the most slightly larger, such fiber optic communication unit can be embedded into the 3rd cylinder arc body
In, form tight fit, will not from the 3rd cylinder arc body effusion, simultaneously fiber optic communication unit and transmission pressure or special-shaped packing gasket,
Or transmission pressure and special-shaped packing gasket tangent, and protective layer is coated on outside cable core, and arbitrary with reinforcement axis perpendicular
Plane on projection on, the circular arc of the circle that all 4th cylinder arc bodies of special-shaped packing gasket are corresponding is on same circumference and this circle
The heart coincides with the center of circle of reinforcement, therefore cable core, protective layer more rounding, optoelectrical cable outward appearance more rounding, smooth；Due to this
The special construction of invention, therefore it is no longer necessary to the wrapping of yarn class material, both provided cost savings, and there is not yarn class thing when variations in temperature
Matter and transmission pressure, protection tube material is because of temperature shrinkage/expand different and prick bad transmission wire, protection pipe, and then affects photoelectricity
The defect of cable performance；Owing to fiber optic communication unit is arranged in the 3rd cylinder arc body dexterously, even therefore big current-carrying capacity, cutting greatly
The transmission of electricity of area lead to, it is not required that make large-sized protection pipe, provide cost savings, make protection pipe more general simultaneously；By
In the present invention, special-shaped packing gasket, transmission pressure, reinforcement are actually parallel mode and arrange, and without yarn class binder, therefore
After workmen's stripping optical cable, it is no longer necessary to cut off yarn class binder, take out corresponding special-shaped packing gasket, the most lightly
Stripping out protection pipe, can realize protecting pipe to separate with special-shaped packing gasket, construction is quite convenient, in hgher efficiency.
Therefore, the optoelectrical cable with special-shaped packing gasket of the present invention has simple in construction, cost is lower, performance is more excellent
Good, the Advantageous Effects such as more convenient of constructing.
