 Fiber-optical socket (versions) / 2345389Invention concerns fibre optics and optronics. It can be applied to linking of groups of fiber-optical cables among themselves. In the socket the centralisers are executed from an elastic material. One of edges of a gash of every centraliser is fixed in a socket material. On other edge from each leg of a tip there are salients. From each leg of the fiber-optical socket the slider is available. There are holdfasts of an open standing of the socket. At centre of each of the socket legs, there are the buttons relieving a holdfast. Each fiber-optical plug has the mobile lattice of squeezing of springs or an elastic material for plug tips springing. In each plug there is a lever. There is a device of fixing of a lattice. Vacuities of the centralisers densely sweep plug tips. Thus moves a slider, fixing a plug in the socket and voiding the mobile lattice for travel. The elastic material creates necessary effort of squeezing of end faces of tips. |

The case has at least three independently opening main clamping sections, with dimensions which allow for directly clamping the naked part of the first and second optical fibres, and at least one additional independently opening clamping section with dimensions which allow for clamping the coated part of one of the optical fibres. Clamping sections are made such that, the first optical fibre can be clamped by the first main clamping section independent of the second optical fibre, making it possible to clamp the first optical fibre from rotation and axial displacement relative the case of the connector, so as to essentially leave untouched the next clamping or unclamping of the second fibre.

FIELD: fiber-optic communications.
SUBSTANCE: device has body and elements for pressurization of light guide. In hollow of body pressurizing element is inserted, in form of resilient compactor vulcanized on optic cable with glue previously applied to vulcanization area and made with conic outer surface at one end, contacting with body, and at other end pressing nut is mounted.

The invention relates to techniques for transmitting signals, in particular to the switching elements of fiber-optic communication lines.
Currently, there is a desperate need for the use of fiber-optic communication lines (FOCL) to display information from cameras, inside of which there is excessive pressure (thermocamera).
The use of fiber optic in the pressurized chambers heretofore been impossible due to the lack of fiber, sealed and shock resistant conductors, through which you can display information through the casing thermocamera measuring complexes.
Known sealed the input fiber of the fiber (C-SC Germany No. 3638549, G 02 B 6/36), based on the sealing of the optical fiber in the hole of the metal parts. The solder out of the hole forms a body, which hermetically covers the core of the optical cable without sheath. Solder coupled with an external area of the metal parts, and with a long stretch of the walls of the hole.
Lack of fiber is that in place of solder optic cable is cleared from the reflective membrane, which leads to a partial loss or distortion of the signal light.
Closest to the invention is that the connector fiber optic cable (A.S. of the Russian Federation No. 1483420, G 02 B 6/36, publ. 30.05.89, BI No. 20)containing cylindrical body with internal thread, clamp nut, elements for clamping the optical fiber and asterousia element in the form of an elastic sleeve.
The disadvantage of this connector fiber is that the design is perfectly sealed, so you cannot use it in pressurized chambers.
The objective of the invention is to provide a hermetic fiber, its use in plants operating under high pressure up to P=14,7·10 6 PA (150 kgf/cm 2 ) and can withstand shock load up to 500, the problem is solved in that in the case of a light guide having a cavity, is inserted sealing element represents vulcanised optic cable elastic seal with pre-applied on-site curing glue and is made with a conical outer surface at one of the ends in contact with the casing, and the other of its end installed the gland nut. Between the guide sleeve and the housing has an o-ring.
Figure 1 shows the structure of an optical fiber.
The fiber consists of a housing 1, which has a seal 2 with pre-terminated optical cable 3, which by means of the gland nut 4 through the sleeve 5 is sealed with the housing 1. The optical cable 3 is fixed relative to the housing 1 of the guide sleeve 6, between them the sealing ring 7. Sleeve 8 are used to otstykovki mates.
Figure 2 shows the design of the seal.
The optical cable 3 is cured sealant from a mixture of rubber.
Assembly is as follows.
The optical cable 3 is cured sealant from a mixture of rubber, for better adhesion to the place vulcanization pre-applied adhesive. The seal has a conical outer surface, which is installed in the housing 1 and sealed by a nut 4 through the sleeve 5. Then install the guide bushing 6 with the sealing rings 7 and sleeve 8 to otstykovki mates.
This constructive solution of the light guide has a number of advantages:
- does not violate the integrity of the sheath of the optical cable that does not lead to a partial loss or distortion of the signal light;
- shape rubber seal allows easy and reliable to seal it in the body of the light guide;
- when installing the rubber seal in the metal housing of the fiber is not necessary to consider the temperature coefficients of expansion of the materials.
