Description

The invention relates to the field of electrical engineering, more specifically to multichannel current-collecting devices used in electronic technology for transmitting electrical control signals and supply voltage of direct and alternating currents from the fixed part of the product to the movable and vice versa. The device can be used in telescopes, robots, military equipment, tower cranes, etc.

A current-collecting device is known that contains two or more pairs of the fixed part of the product located in the radial direction and movable with insulated flat and lobe electrical contacts placed on them, communicated through wires with external electrical connectors (patent RU No. 22678840, H01R 39/00, 2006.01.08) .

This device makes it possible to place high-current contact rings on one pair of the fixed part of the product and the moving one, and low-current on the other. However, this design of the device is characterized by large dimensions in the transverse direction, which limits its use in units where the transmission of strong currents of various sizes is required with a relatively small transverse direction of the mounting device in which this device should be placed.

This design of a multi-channel sliding current collector is too complicated and has a sufficiently large axial and transverse dimensions.

Among the known analogues of the claimed technical solution, the closest (prototype) can be a multi-channel sliding current collector containing a housing, inside of which there is a central shaft mounted on sliding bearings, fixed and moving parts and a current collection part from the group of kinematically connected to the housing and the central shaft and interacting between by means of flat and flap electrical contacts communicated through wires with external electrical connectors (patent RU 2 193810, H01R 39/02, 39/08, 2000.11.10).

Due to the difficult kinematic connection of the electrical contacts with the housing and the central shaft, access to the wiring (soldering) of wires to the electrical contacts is difficult, in addition, it is impossible to replace failed electrical contacts without completely disassembling the device.

The inventive multi-channel sliding current collector (figure 1) contains a housing 1 made in the form of a cylinder, inside of which is mounted on the bearing bearings 2, 3 the central shaft 4 and coaxially to the central shaft are assembled into a bag and pulled together by circumferential tie rods 5 tier-mounted blocks 6 , which are functionally complete compact electrical modules with a sufficient number of current collection circuits for transmitting electrical signals of various frequencies and powers. The blocks are protected from being influenced by copper screens 7.

Each of the blocks included in the package (Fig. 6) is technologically an independent assembly unit with a collector part of non-rotatable 8 and rotatable 9 electrical contacts forming contact pairs concentrically grouped in accordance with the purpose of two groups of parallel circuits for transmitting electrical signals of different power and frequencies.

Through the wires 10, 11 (figure 2) each contact pair is in communication with the corresponding external electrical connectors, upper 12 and lower 13.

The block is made in the form of a fixed cylindrical metal, for example aluminum, holder 14 with longitudinally oriented on the outside, made on the inner diameter of the housing segments 15 (figure 2).

The ends of the cage above and below are closed with screwed-on screws 16 with insulating covers 17 made of dielectric material, for example fiberglass. A disk holder 18 (FIG. 6) of insulating material, for example fibrous plastic, is glued to the inner surface of each insulating cover.

Between the disk holders is a rotating disk 19 made of two layers of insulating material, for example fiber plastic, between which a copper screen 20 is installed, which protects the circuit of electrical signals from influencing each other.

Non-rotating electrical contacts 8 are made in the form of combs (Fig. 7) made of spring-conducting conductive material, such as beryllium bronze, and are mounted in the bodies of the disk holders 18 concentric with respect to the central shaft 4 with crescent rings with lead ends 21 (Fig. 2) located above the surface holders in the radial windows 22 made in the place of their location in the insulating covers, and in the form of a broken shape with a variable angle of inclination, uniformly spaced along the circumference of the petal contacts 23 (Fig. 8) it is to the plane of contact of the two mating sections with the convex side facing the central shaft. In order to avoid uneven contact forces caused by wear of the flap contacts, the internal angle of fracture is 171-173 °, providing a variable angle of inclination of their ends 24 and their associated sections 25 relative to the plane of contact equal to 3-5 ° and 15-16 °, respectively. Moreover, the last angle is made somewhat larger by an amount that provides the necessary force in the assembly of preloading the extreme part of the petal contact to the contact plane (Fig. 9).

The segments 15 of the cage of each of the unit block packages form, with the inner surface of the casing, longitudinal longitudinal channels 26 for laying wires from the non-rotating electrical contacts 8 to the lower external electrical connectors 13. A local radial channel 27 is made on the side wall of each radial window 22 on both insulating covers 17 of the cage (figure 2), communicating with the output channel of the wiring 26. In this case, the cross-sectional areas of the local radial channels 27 and the output channels of the wiring are not rotatable x electrical contacts exceed the total cross-sectional area of the wires 11 laid through them.

The Central shaft 4 is made in the form of a cross-shaped rod in the cross-section, configuration (Fig. 2), forming, with the blocks included in the package, through longitudinal output channels 28 for conducting wires from the rotary electrical contacts 9 to the upper electrical connectors 12. On one of the ribs of the central cross the shaft has a longitudinal groove 29.

Rotary electrical contacts are made in the form of flat metal rings located concentrically to the central shaft on opposite planes of the rotating disk 19 (Figs. 13, 14), fixed by gluing in the annular grooves 30, each of which is mated on both planes of the rotating disk with the central axis located on one side shaft corresponding local radial channels 31, the axes of which converge in the center of the rotating disk.

The rotating disk is connected to the central shaft by means of a dowel of dielectric material made in the form of a pin 32 with a head 33 (Fig. 6), profiled along the cross section of the longitudinal groove of the central shaft. The head of the embedded key is installed in the longitudinal groove 29 of the central shaft by fixing the rotating disk 19 in the circumferential direction and when forming the package with the possibility of axial movement of the block 6. The pin of the embedded key is installed in the hole 34 (Fig. 10), made in a metal sleeve pressed into the rotating disk 35. For the orientation of the radial channels 31 of the rotating disk relative to the output channel 28 of the wiring to the upper electrical connectors 12, a keyway 36 is made in the metal sleeve (fi d.11). The position of the metal sleeve is fixed by means of a pin 37 that interacts with the washer 38. A thrust disk 39 is connected with a cage by a thrust bearing 39 orienting it relative to the disk holders (Fig. 6), made in the form of rings of antifriction material, for example fluoroplastic.

Each of the blocks included in the metal sleeve 35 of the rotating disk has diametrically located local radial channels 40 (Fig. 10) for each layer of the rotating disk with a width equal to the total width of the radial channels 31 of the rotating disk included in its inner diameter on one side, and from the side of the central shaft - the width of the output channel 28 laying wires from rotary electrical contacts. The cross-sectional areas of these channels 40 of the metal sleeve and the output channels 28 of the wiring of the central shaft exceed the total cross-sectional area of the wires 10 laid through them to the upper external electrical connectors 12.

The wires laid in the channels 28 for laying the wires of the central shaft of the wire are protected from abrasion by the fixed parts (insulating covers 17 with disk holders 18) of the blocks installed on the outer diameter of the shaft between the blocks 6 by dielectric bushings 41.

For uniform dispersion of the wires 10 in the output channels of the gasket coming from the rotary electrical contacts, the position of the keyway 36 of each metal sleeve 35 of the subsequent rotating disk should be offset 90 ° relative to the previous one (Fig. 16). The metal sleeve is pressed in when the radial channels 40 in it are combined with the radial channels 31 on both planes of the rotating disk.

The upper bearing support of the central shaft is located in the sleeve 42, made with a flange 43, docked by screws 44 to the flange 45 of the housing. In the inner cavity of the sleeve there is a bowl 46 with a hub 47 connected to the central shaft identical to the connection of the rotating disks with the help of the key 48, while a keyway 49 is made under its pin on the outside of the hub (Fig. 15).

The central shaft is axially fixed by a spring element 50 in the form of an O-ring sandwiched between the chamfer 51 (Fig. 5) in the bore hole of the pressure cover 52 and the annular groove 53 (Fig. 15) of the bowl hub. The hub racks 54 are formed by vertically oriented crosswise lying through grooves 55 located opposite the output channels of the wire routing 28 from the rotary electrical contacts and equal in width with them.

The clamping cover 52 in the form of a disk by means of screws 56 is mounted on the struts of the hub. Windows 57 are made in the lid, in which upper external electrical connectors are installed.

The diametrically located protrusions 58 are made in the lower part on the inner walls of the housing. The removable bottom 60 in the form of a cross with the lower bearing support of the central shaft located in the central part is fixed below to the protrusions by means of bolts 59 (not shown). In the removable bottom, grooves 61 are made, in which nuts 62 are mounted fastening the tie rods 5 of the bag.

The lower bearing support is closed by a thin-walled protective casing 63, screwed to the crosspiece with screws 64.

By means of fasteners 65, a lower glass 66 is attached to the bottom with lower external electrical connectors mounted thereon.

In accordance with the purpose (depending on the number of contact pairs in one circuit), it is possible to form high-current power, control low-current and high-frequency blocks without changing the overall transverse dimensions of the device.

In the proposed device:

- through the contact pairs of the control low-current unit, where digital signals of the Manchester-II type RS-422, RS-232, pulse currents up to 1A with a frequency of up to 18 kHz, voltage up to 27V are transmitted;

- direct currents up to 18A, 27V and alternating currents up to 11A, 380V, 50 Hz are transmitted through the contact pairs of the power high-current block.

The assembly of the inventive multi-channel sliding current collector is quite simple and is as follows.

To facilitate the laying of wires in the longitudinal output channels of laying wires to the lower electrical connectors from fixed electrical contacts, blocks with wires of a larger cross section (high-current power blocks) must be installed closer to the upper shaft support.

Since each block 6 is already an assembly unit, therefore, first check the blocks with wires 10 and 11 soldered to them, which must be prepared to ensure that they are pulled through the output channels of the wiring to external electrical connectors. In the metal bushings 35 of the rotating disks 19, the pins 32 of the dowels must be laid, and on the insulating covers 17 of the blocks that will face the upper bearing support 2, starting from the second block, shields 7 should be installed.

The first block 6 is put on the central shaft 4 from the lower end with simultaneous stringing onto the tie rods 5, combining the head 33 of the embedded key of the rotating disk 19 with the longitudinal groove 29 of the central shaft, move the first block along the axis of the central shaft along the longitudinal groove to the upper end of the shaft. The wires 10 from the rotary electrical contacts 9 are laid in the output channel of the cable wires 28 of the shaft next to the longitudinal groove 29 of the shaft, then a protective dielectric sleeve 41 is put on the shaft (Fig. 16, pos. A).

Turn the shaft with the first block clockwise 90 °. Then they take the second block 6 and put it on the lower end of the shaft with the screen 7 towards the first block, while aligning the head 33 of the embedded key of the rotating disk with the longitudinal groove 29 of the central shaft 4 while dragging the wires 10 into the next output channel 28 of the shaft, covered by the first block with a protective dielectric sleeve 41 (Fig.16, pos. b).

The shaft is again rotated together with the two blocks already strung on it by 90 °, the protective dielectric sleeve 41 is put on and the third block is strung (Fig. 16, pos. C).

So all the blocks are gradually assembled, forming as a whole a multi-tiered package on the shaft. The wires 11 from the non-rotating electrical contacts 8 are evenly stacked in the assembly of blocks between the segments 15 of the clips 14.

When the bag is assembled, the housing 1 is put on it from the lower end of the shaft, so that the ends of the ties 5 fall into the holes of the protrusions 58 of the housing and wires 11 laid between the segments 15 of the cages are output without interference.

Using nuts 62, the package of blocks is pressed against the protrusions 58 of the housing 1. Then, a removable bottom 60 is mounted and bolted 59 from below to the protrusions of the housing, in which the lower bearing support 3 of the shaft is assembled, and then closed with a protective casing 63. After that, a sleeve is mounted on the central shaft 42 with the upper bearing support 2 of the shaft, pulling the ends of the wires 10 through the inner ring of the upper bearing support, and, aligning the flange 43 of the sleeve with the flange 45 of the housing, secure it with screws 44.

A mortise key 48 is installed in the hub 47 of the bowl 46, made identical to the rotating disks, and, dragging the wires 10 through the through grooves 55 in the hub, fix the cup on the shaft with a spring element 50. Then, the wires 10 are grouped in accordance with the marking indicating their belonging to external electrical connectors, having previously pulled them into the windows 57 of the pressure cover 52, corresponding to each of the upper external electrical connectors of the group of wires. The supply of wires is laid inside the bowl, which is pressed by the clamping cover 52, screwing it with screws 56 on the uprights 54 of the hub.

To the removable bottom 60 of the housing is docked by means of fasteners 65 the lower glass 66, after pulling in each place the corresponding group of wires 11.

The ends of the wires in accordance with the marking are soldered to the lower 13 and upper 12 electrical connectors. The connectors are attached to the corresponding places on the pressure cap of the bowl 46 and on the lower glass 66.

Dismantling is carried out in the reverse order.

The claimed current collector works as follows. The rotating disks 19 rotate together with the central shaft 4, while the flat rings of the rotary electrical contacts 9 slide relative to the tab contacts 23, due to which the electrical connection is made between the rotating devices connected by wires 10 with rotary electrical contacts and fixed, connected wires 11 with non-rotary electrical contacts.

The effectiveness of the technical solutions incorporated into the design of the inventive multi-channel sliding current collector, as well as the possibility of obtaining the aforementioned technical solution during the implementation of the invention, consists in simplifying its design and improving technical and operational qualities, which is confirmed by the corresponding results of experimental verification of the main solutions for design optimization.

The inventive multi-channel sliding current collector is simple in design, has a small mass and dimensions with a sufficient number of current collection circuits of electrical signals of various frequencies and powers. Such a current collector makes it possible to simultaneously receive the necessary number of useful signals, as well as to ensure, as the friction ring elements of the electric signal channels wear, it is easy to replace any unit of the multi-tiered package.
