Easily-separated cluster optical cable

Technical Field

The utility model relates to an optical cable, in particular to a bundling optical cable easy to separate.

Background

With intensive deployment of 5G networks, infrastructures such as 5G base stations are also built on a large scale. Compared with 4G, 5G has a small coverage area of the base station due to high frequency points, and needs a large amount of base station equipment. It is estimated that the amount of construction of 5G base stations is at least 5 times that of 4G base stations when equivalent coverage is achieved. Under the premise of wide construction of 5G, site resources are more scarce, and particularly, high-quality site resources with better power supply and network environments are provided. And the PoE technology using the digital communication cable, the photoelectric mixed cable or other power supply communication cable integrated scheme can simultaneously supply power and transmit signals by using only one cable, thereby greatly saving the wiring cost, enabling the selection of the station address to be more flexible and saving a large amount of wiring cost. When traditional optical cable branched, need cut open the optical cable or cut off partly to just can be connected with the optical cable connecting box after handling the inside optic fibre of optical cable, complex operation, time-consuming and energy-consuming, inefficiency, joint length when still remaining the optical cable to lay moreover, more can influence optical cable information transmission's accuracy and stability because the optical cable increases transmission loss and produces the trouble.

In order to solve the above problems, in the prior art, a plurality of butterfly units are bundled together to form a cable core and are arranged in an optical cable, but the plurality of butterfly units are wrapped together by using a sheath to form the optical cable, and the sheath needs to be completely peeled off to separate the butterfly units during connection, so that point-to-point connection can be realized only, and a single butterfly unit cannot be separated midway.

The utility model is further described with reference to the following detailed description and accompanying drawings.

Referring to fig. 1, an easy-to-separate bundled optical cable includes an inner core 1, an insulating layer 2, a reinforcing sleeve 3, a connecting sleeve 4, and a plurality of isolation sleeves 5 and butterfly optical fibers 6, wherein the inner core 1 is disposed at the center of the optical cable, the insulating layer 2 is wrapped outside the inner core 1, the reinforcing sleeve 3 is wrapped outside the insulating layer 2, the connecting sleeve 4 is wrapped outside the reinforcing sleeve 3, the plurality of butterfly optical fibers 6 are respectively wrapped by the plurality of isolation sleeves 5 and are disposed on the outer surface of the connecting sleeve 4, and two sides of the plurality of isolation sleeves 5 are tightly attached to each other; the outer surface of the reinforcing sleeve 3 is provided with a plurality of raised ribs 31, the number of the raised ribs 31 is the same as that of the isolation sleeves 5, and the ribs 31 penetrate through the connecting sleeve 4 and are arranged between the two isolation sleeves 5, so that the isolation sleeves 5 are easy to separate.

It should be noted that the ribs 31 are longitudinally spaced apart on the reinforcing sleeve 3, so that the connecting sleeve 4 is kept as a whole and is not divided by the ribs 31.

It is worth mentioning that the inner core 1 is made of metal, and due to the existence of the insulating layer 2, the inner core 1 can be used as a signal line or an electric wire, so that the optical cable has a function of transmitting an electric signal.

Preferably, the two sides of each isolation sleeve 5 are bonded through glue, so that the isolation sleeves are convenient to tear, and the isolation sleeves 5 are prevented from being broken when being torn due to over-tight high-temperature bonding.

The principle of the utility model is as follows: during polymerization, the bottom of each isolation sleeve 5 is connected with the connecting sleeve 4 and mutually bonded, so that the optical cables are in a bundling state; when a certain optical fiber needs to be stripped, the optical fiber is directly pulled out to separate the isolation sleeve 5 from the connecting sleeve 4, and the reinforcing sleeve 3 is made of metal, so that the viscosity between the optical fiber and the isolation sleeve 5 is not high, the isolation sleeve 5 and the connecting sleeve 4 are separated, the isolation sleeves 5 on two adjacent sides are prevented from being taken out when the certain optical fiber is stripped, and the separation of a single optical fiber is realized while the residual optical fibers are still in a bundling state.

The design key point of the utility model is that the isolation sleeve is favorable for wrapping a plurality of optical fibers independently and then adhering the optical fibers to each other, so that the optical fibers are convenient to strip, and simultaneously, each optical fiber can be stripped independently without decomposing the whole optical cable.
