Abstract

The invention relates to the field of mechanical engineering and relates to devices for connecting hoses and flexible pipelines containing elements of fiber-optic communication lines. The hoses are coupled by means of two rigid hemispheres to which power flexible cables are attached, inside which a rigid optical fiber connector is placed, while two flexible clips are tightly connected to the couplings, which end with metal clips having a fitting for hermetic fiber insertion. Sections of abutting hoses are sealed by hermetically connected shells. The fiber is withdrawn from the sections through the hermetic reinforcement of the clip. The fiber is jointed at the connector, the excess fiber is placed in a flexible cage, then the coupling halves are joined and a pipeline consisting of the joined sealed sections is obtained. 1 il.

Description

The invention relates to devices for connecting fiber-optic cables and flexible pipelines containing elements of fiber-optic communication lines.

The aim of the invention is to simplify the design and reduce the size of the device through the use of flexible elements instead of a rigid docking station. g

The drawing shows a structural diagram of the proposed device.

The device consists of cable sections 1 containing a flexible sheath 2, rigid elements 3, fiber (internal flexible element) 4, power flexible cables 5, rigid coupling halves 6, consisting of end and internal rigid clips 7 and 8, connected

flexible sleeve 9, as well as hermetically | The first input is 10 optical fibers and a rigid connector .11 optical fibers, common to two mating sections. For convenience of winding on the drum and in order to avoid damage to the cable, any rigid elements inside the cable should be placed in it with a certain interval | and the length of each rigid element should satisfy the condition

The hard part of the docking station must also have a length of 1 in order not to disturb the homogeneity of the cable assembled from separate sections. At the same time, a rigid connector of optical fibers with a length of 1 (and 1 is always less than 1), technological reserve of optical fiber with a length of 9 1 1 on each side of the connector and hermetic input (14 1 1) of fiber

the cavity of the cable into the cavity of the docking station, since the cable section must be sealed. At the same time, power flexible cables inside the hermetic volume should be attached to the coupling couplings of the docking station. Thus, the total length L of the docked coupling half couplings is equal to

L - 2 (1, + 1 „.) -F I

 3-5 are inside the flexible sheath, and the ends of the optical fiber are extended through a sealed lead outside the cable section.

To connect the cable sections between each other, it is necessary to first join (the ends of the fiber 4 in the connector 11. For this procedure, the details 7 of the joined sections are not brought close to each other, but are placed at a distance determined by the technology of embedding the fiber into the connector 11. For the same the reason there is a technological

After this, the parts 7 of the connected cable sections can be joined, the docking assembly will be assembled, a connector inside and a section connected by the formula d 1/2, because of the dinene between them.

The device works as follows.

Sections of connectable cables are sealed by hermetically connected parts 2 and 6. Fiber 4 is withdrawn from the section through hermetic reinforcement 10 of the sleeve 8, the fiber is joined in connector 11, the technological components of excess fiber lg are placed in flexible sleeve 9, then the coupling half 6 join and receive cable consisting of docked sealed sections. At the same time, inside the sections there are rigid elements of length 1, and the docking assembly itself does not have any rigid elements of length more than 1.

The technological process of assembling the cable is carried out as follows.

Assemble the half-couplings 6 of the parts 7-10. The power flexible trofles 5 are fastened to rigid collars 7. The ends of the fiber 4 connecting the rigid elements 3, which may contain both connectors 11 and other nodes of similar dimensions, are fastened through a sealed inlet 10.
