EXAMPLE 6

Referring to fig. 16, and referring to embodiment example 1, a communication optical cable is substantially the same as embodiment example 5 except that: the open ends of the second cavity are distributed along the same direction; in fig. 16, the distribution is clockwise or counterclockwise.

EXAMPLES example 7

Referring to fig. 17, a communication optical cable is described with reference to embodiment 6 and embodiment 3, except that: the reinforcing member 1 has three receiving parts 3 outside, each of which has a light transmitting member 9 inside, and the three receiving parts of the inner ring have the same outer portions as those of embodiment 6.

Of course, the distribution of the open ends of the second cavities of the accommodating parts of the inner ring may be distributed along the same direction as that of embodiment example 6, or may not be distributed along the same direction; similarly, the distribution of the opening ends of the second cavities of the housing parts of the outer ring may be distributed in the same direction as in embodiment example 6, or may not be distributed in the same direction.

The present embodiment increases the optical communication transmission capacity, and in addition, the reinforcing member can be eliminated.

With reference to embodiments 1-3 and 5-7, an optical-electrical composite cable may be formed by partially housing a light-transmitting member and partially housing a light-transmitting member.

In the present application, the reinforcing member may not have, nor have the loose tube.

In the present application, part of the housing part may not have the power transmission part and the light transmission part; this saves construction costs, for example, in embodiments where the six housing parts do not have power and light transmission parts, which increases delivery speed, for example, for producing five-core cables.

In the application, only the accommodating part needs to be taken out, and the third bending part 31, the second connecting part 32 and the fourth bending part 33 are rotated outwards, so that a stripping mode is realized, the power transmission part or the light transmission part can be conveniently taken out, a professional stripping tool is not needed, and the operation efficiency is improved; the third connection part 34 skillfully realizes the floating fixation or clamping of the power transmission component or the light transmission component; on the other hand, the open structure makes the heat dissipation effect of the conductor better, and the heat can be dissipated from the second cavity 30.

In this application, when the power transmission part is soft enough, can directly pull out from the 30 openings of second cavity, not confine during production to putting into together, fill in after can having done the holding part. Similarly, the light transmitting component is soft enough and has a larger strength, and can be directly pulled out from the opening of the second cavity 30, and is not limited to be put into the second cavity together during production, and can be plugged after being made into a containing component. Thus, the inspection, construction and production are all very convenient.

In the application, when the power transmission component and the light transmission component are damaged, the power transmission component and the light transmission component can be taken out independently and replaced well, so that the cost is saved; in the closed structure in the prior art, such as a cylindrical structure, the insulating layer needs to be stripped, the stripping blade is easy to damage and even break the inner conductor and the optical fiber, and the thinner cylinder is difficult to strip and has low efficiency; after the cable is used for a long time, the conductor is easy to be bonded with the insulating layer into a whole, so that stripping is quite troublesome, the stripping rate is extremely high, the whole power transmission/light transmission component is scrapped after the cable is damaged, and the corresponding phenomenon cannot occur in the cable.

In the prior art, the optical fiber ribbon has two modes, one mode is a single-layer ribbon shape, the more the number of cores is, the longer the width is, however, when the overlong optical fiber ribbon is used for producing the loose tube, the diameter of the loose tube is inevitably increased, so that the diameter of a product is increased, and the cost is increased; therefore, a plurality of narrow sleeves are produced firstly, and then the plurality of narrow sleeves are stacked to achieve the purpose of reducing the size of the loose sleeve; the volume is reduced by adopting the bent shape, the production is easy, the material consumption is less, and the cost is lower; further, as a further improvement, it is possible to provide the optical fiber ribbon with a plurality of bends so that it is formed into a plurality of layers, not limited to two layers in the embodiment example, which significantly increases the communication capacity; another way is a sector-shaped cross-section, which is obviously not suitable for use in this application.

In the prior art, a plurality of cylindrical sleeves are adopted to form one layer in the stranded optical cable, so that the optical fiber in the loose sleeve meets the requirements of temperature, environment, mechanics and other properties, the loose sleeve needs to have enough size, the too large size causes the defects of too large material consumption, too large outer diameter, too high cost, difficult construction, large occupied space and the like, and the too small size causes the performance of temperature, environment, mechanics and the like to be not up to standard or even the optical fiber to be broken; secondly, in order to realize large core number, the optical fiber ribbon sleeve has larger diameter, higher cost and extremely inflexible performance; thirdly, in order to increase the number of cores, a multi-layer or multi-ring mode is adopted, in order to stabilize the product structure, the outer ring needs to be tangent to the inner ring, and loose tubes in the outer ring need to be tangent to each other; therefore, in combination with the above, the loose tubes of the inner layer and the outer layer need to be matched to realize sufficient core number expansion, and the tangent principle needs to be met, so that the random combination of the inner ring and the outer ring is difficult to realize structurally, and the inner ring 6, the outer ring 12, the inner ring 9 and the outer ring 15 and the like are commonly used; the application overcomes the defects, and the inside and the outside can be combined flexibly; the increase of quantity in fourth, the round to prior art's layer stranded cable, means that the stranding device of the layer stranded cable that the cost is expensive, take up an area of much is more complicated, and in this application, only need realize through the mould, can accomplish at the sheath process, has saved the input of equipment, only needs the mould, and the cost greatly reduces.

The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limiting the present invention. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
