Description

A multi-channel rotating connector for optical cables is intended for use in the field of communication for transmitting information from rotating objects or to rotating objects via fiber-optic cables.

A rotary connector for optical cables is known, which comprises a housing, on both sides of which bushings with cables passing through them are installed, one of the bushings is mounted rotatably, the other bush is fixed, the ferrule is installed inside the housing, the sleeve mounted for rotation is made with the narrow part, on which the bearings are located with a separating ring between them, attached to the housing, the ferrule is connected to a fixed sleeve and is made with a side cut in The stripped ends of the optical fibers of the cables are located, the side cut of the ferrule and the free space of the case are filled with silicone gel (US Pat. RF No. 2402794, dated October 27, 2010). The disadvantage of this design is the limited scope due to the connection of two cables.

A rotating connector for optical cables is known, comprising a housing in which two nodes with guide sleeves are mounted on the opposite, in which optical cables are fixed, one of the nodes is rotatable, and the other node is fixed, between the guide sleeves there is an optical element in the form of a prism, bushings fixed rods are fixed, representing the rods with a cross-section, in the grooves of which are installed optical cables, the ends of which are connected to gradan (Pat. RF №108646, 09/20/2011). The disadvantage of this design is its complexity.

Closest to the claimed utility model is a two-channel two-mode rotating connector (US Pat. US No. 7515782, 04/07/2009), consisting of two channels of fiber-optic rotational interface, holders rotating relative to each other, on which two micro-collimators are mounted. The first light transmission channel consists of a micro-collimator that is mounted on the geometric axis of the holder, and another micro-collimator is mounted on the other axis of the holder. Two micro-collimators are located opposite each other and parallel to the beam of light emitted from one micro-collimator, which is transmitted to the other micro-collimator via rotational interfaces. The second passage light channel includes conventional collimators that are installed inside the collimator holders, respectively, with reflective surfaces. The inclined surfaces on the holders are coated with an optical reflective surface. Reflective surfaces are attached to the angular surface of the holders and parallel to the optical surface, respectively. When light is emitted from one of the collimators, it will be reflected on reflective surfaces, and then sent to another collimator. The second light path is formed during rotation. Thus, two passive channels of light are obtained.

The disadvantage of a two-channel two-mode rotating connector is its limited capabilities due to the transmission of light through only two pairs of active channels.

The technical result of the utility model is to simplify the design and technology of its manufacture.

The technical result is achieved by the fact that the rotating connector contains a housing with a cover, in which there are disks with the possibility of synchronous rotation around a common axis, holes for optical channels are made in the disks, optical cables with mating nodes are connected to the first disk and to the case, in the second disk with two reflectors are installed on each side, one of which is located at the intersection with the axis of rotation, a transparent plate is installed between the disks, on each side of which there is a reflector located at the intersection with the axis of rotation of the discs.

The disks are mounted in a bearing housing.

Optical cables are connected to the first drive and to the chassis through expanders.

The disks are made with gear rims connected by a common gear located in the housing.

There is a leash on the input disk for kinematic communication with a rotating object.

A multi-channel rotating connector is illustrated by drawings, where:

Figure 1 presents a section of the device;

Figure 2 presents a front view of the device

Figure 1 shows a multi-channel rotating connector, which consists of a housing 21 with a cover 22, with a first disk 23 and a second disk 24, mounted for rotation around a common axis OO on bearings 19 and 20. In the second disk there is an opening for optical canal and gear rims. In the case, on the one hand, the first disk 23 is installed, to which optical cables 1, 2, and 3 are connected with the docking nodes 7, 8 and 9, which are plugs. The luminous flux expanders (gradanas) 13, 14 and 15 are installed in the first disk. On this disk there is a leash 33 for kinematic communication with a rotating object. Optical cables 4, 5 and 6 are connected to the case.

The second disk has an opening for the optical channel and on each side of the disk there are two reflectors 29, 30 on one side and two reflectors 31, 32 on the other side. Moreover, one reflector 30, 31 on each side of the disk is installed at the intersection with the axis of rotation of the disk.

Between the disks 23 and 24, a transparent plate 26 is installed, on each side of which there are reflectors 27 and 28, located at the intersection with the axis of rotation of the disks. Gradients 16, 17 and 18 are placed on the housing, to which optical cables 4, 5 and 6 are connected through the docking nodes 10, 11 and 12.

The gear crowns of the disks 23 and 24 are connected by a common gear 25 (Fig. 2), which ensures synchronization of rotation of the disks.

During operation, the connector provides 3 optical communication channels.

In the first channel, the luminous flux from cable 2 through gradan 14 enters the reflector 27, from which through gradan 16 it enters cable 4. In the second channel, the luminous flux from cable 1 through gradan 13 enters the reflector 29. The location of the reflectors 29 and 30 allows luminous flux with the axis of rotation of the connector and direct it to the stationary reflector 28 and from it through gradan 17 in cable 5.

In the third channel, the light flux from the cable 3 through the gradan 15 is the transparent plate 26 and the hole in the disk 24 falls on the reflector 32, from which it is directed to the cable 6 located along the axis of rotation 31 and then through the gradan 18.

During operation, both disks 23 and 24 rotate synchronously, so the location of the light flux relative to the disks 23 and 24 does not change and the connection of the optical channels is independent of rotation. The design of a multi-channel rotating connector is not limited to connecting only the above 3 optical cables. It allows you to connect more optical cables. When the design is increased, an additional pair is introduced into each pair of optical cables - a transparent plate and a disk.

Due to this design, the rotating connector has a simpler design and simplified manufacturing technology due to the lack of complex prism manufacturing technology.
