Description
Technical Field
The invention relates to a novel high-efficiency armored optical cable, which is a novel product in the application field of fiber lasers.
Background
As the demand for fiber lasers increases, the laser transmission cable is used as a key device of the fiber lasers, and the output of the laser transmission cable is also increased. In the production process of the laser transmission optical cable, one procedure is to manufacture an armored optical cable. The conventional armored optical cable structure has two types, the first structure has two layers, and the outer wall of the metal hose is coated with a layer of plastic, as shown in fig. 2; the second construction has three layers, with a woven mesh added between the metal hose and the outer coated plastic layer, as shown in fig. 3. Most manufacturers in the industry need to penetrate the plastic inner sleeve into the metal armored hose, and some manufacturers need to penetrate the signal monitoring line into the plastic inner sleeve again, so that inconvenience is caused in fiber penetration. The threading of the plastic inner jacket tube and the signal monitoring wires into the interior of a conventional armored cable is time consuming and labor intensive, and is difficult to accomplish by human labor alone, especially when long armored cables are to be made. This also becomes a process bottleneck in the industry.
Disclosure of Invention
The invention aims to overcome the defects of the problems and provide a novel high-efficiency armored optical cable. The invention is mainly characterized in that the plastic inner sleeve and the signal monitoring wire are integrated into the armored optical cable, solves the technological problem that the two are required to be assembled in the later period.
The technical scheme of the invention is as follows:
the utility model provides a novel high-efficient armoured optical cable, includes plastics interior sleeve pipe, metal establishment layer, signal monitoring line, transition layer and overburden, its characterized in that: the structure has five layers, which are distributed from inside to outside according to the sequence of the plastic inner sleeve, the metal braiding layer, the signal monitoring line, the transition layer and the coating layer, the whole structure is a whole, the whole structure is not detachable, the relative position can not be adjusted, and each layer can not be drawn inside.
The plastic inner sleeve is of a hollow structure with a cylindrical annular section, is made of antistatic and insulating materials, has a smooth inner wall surface, solves the problem of penetrating into an armored optical cable, has a smooth inner surface, is antistatic, and can ensure that the resistance of an optical fiber is as small as possible when penetrating into the plastic inner sleeve. The metal braid is firmly sleeved on the surface of the plastic inner sleeve through tension and internal and external friction, mainly plays a role in shielding and protecting signals, and can improve the tensile strength of the optical cable.
The metal braiding layer is of a hollow tubular structure and is braided by fine metal wires.
The outside of the metal braiding layer is uniformly distributed with 3 signal monitoring lines along the radial direction, and the signal lines are limited and fastened on the surface of the metal braiding layer through the transition layer. The built-in signal monitoring line solves the problem of penetrating the built-in signal monitoring line into the plastic inner sleeve, and has the function of transmitting electric signals of the laser transmission optical cable outgoing optical head and the laser.
The transition layer is a hollow structure with a cylindrical ring-shaped section, and is made of a material which is convenient for cladding and bonding of the cladding layer. The transition layer is required to ensure that the monitoring lines are uniformly distributed, so that the coating layer cannot bulge, and the coating bonding strength of the coating layer is ensured.
The mechanical properties and thickness of the transition layer and the cladding layer play a decisive role in the strength and bending radius of the armored cable, and the appearance size can be controlled.
Before the armored optical cable is used, the coating layer is sometimes required to be stripped, and the plastic inner sleeve and the signal monitoring wires are exposed. When the fiber-optic cable is used, the problem that the plastic inner sleeve and the signal monitoring wire penetrate into the metal armoured hose is not needed to be considered any more, and the fiber-optic cable can be directly penetrated into the plastic inner sleeve.
In the manufacturing process of the armored optical cable, the plastic inner sleeve and the signal monitoring wire are integrated in the same optical cable through corresponding processes. Compared with the conventional armored optical cable, the invention has the following advantages:
1. the invention saves labor cost, and solves the complex operation problem of penetrating the plastic inner sleeve first and then penetrating the signal monitoring wire into the plastic inner sleeve by integrating the plastic inner sleeve and the signal monitoring wire in the armored optical cable.
2. The functions are more complete. The conventional armored optical cable is not provided with signal monitoring wires, and the signal monitoring wires on the armored optical cable can be directly used without additional reloading.
The invention can be widely popularized to the field of fiber lasers, and is convenient and efficient to operate. Before this, there is no introduction of the armored cable with this structure at home and abroad.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
The conventional armored optical cable structure has two types, the first structure has two layers, and the outer wall of the metal hose is coated with a layer of plastic, as shown in fig. 2; the second construction has three layers, with a woven mesh added between the metal hose and the outer coated plastic layer, as shown in fig. 3.
As shown in fig. 1, the armored fiber optic cable of the present invention, the device comprises a plastic inner sleeve 101, a metal braiding layer 102, 3 signal monitoring lines 103, a transition layer 104 and a coating layer 105, and is characterized in that: the structure has five layers, the whole structure is a non-detachable whole body, the relative positions of the layers cannot be adjusted, and all the layers cannot be drawn inside according to the sequence of the plastic inner sleeve 101, the metal braiding layer 102, the signal monitoring line 103, the transition layer 104 and the coating layer 105.
The plastic inner sleeve 101 is of a hollow structure with a cylindrical annular section, is made of antistatic and insulating materials, has a smooth inner wall surface, solves the problem of penetrating into an armored optical cable, has a smooth surface, is antistatic, and can ensure that the resistance is as small as possible when an optical fiber penetrates into the plastic inner sleeve 101. The metal braid 102 is a hollow tubular structure woven from fine metal wires. The metal braid 102 is firmly sleeved on the surface of the plastic inner sleeve 101 through tension and internal and external friction, mainly plays a role in shielding and protecting signals, and can improve the tensile strength of the optical cable.
