provide transmission of electrical information signals from the fixed part of the object to the rotating part. The purpose of the invention is to increase the service life of the device by reducing the wear of the contact coating, which provides low contact resistance. The device consists of concentrically located stationary 1 and rotating current-conducting rings, between which there is an elastic current-conducting element, made in the form of an elastic ring-shaped carrier 7 with uniformly rigid contact elements 9 on it, electrically connected. 2 Il.

The invention relates to electrical engineering in terms of the creation of current-collecting devices () that ensure the transmission of electrical information signals from the unattached part of an object to a rotating one.

The aim of the invention is to increase the service life of the device.

FIG. 1 shows the toss-device; in fig. 2 shows section A-A in FIG. one.

The current collection device consists of a fixed conductive ring 1, a rotating conductive ring 2, which is mounted on an insulating sleeve 3, which is rigidly connected to the shaft 4 by means of a key 5. The rings 1 and 2 are arranged concentrically, and

However, the elastic properties of the carrier can be provided by the properties of the carrier material itself, or the carrier can be made of metal, simultaneously carrying out an electrical connection between the rigid contact elements 9, for example, in the form of a flat spring. On the working surface of the hard contact elements can be coated, providing a small transitional contact: on resistance.

which can be reinforced with a flat spring 8. On the carrier 7, for example, rigid metallic contact elements 9, electrically interconnected, for example, flexible conductors 10, are evenly spaced.

The device works as follows.

When the shaft 4 rotates, the insulating sleeve 3 and the conductive ring 2 rotate with it. At the same time, the elastic element 6 rolls in the gap between the movable 2 and the fixed 1 rings, making electrical contact between them.

In the embodiment of the device (Fig. 2), the elastic conductive carrier is made in the form of an elastic annular rubber carrier 7 reinforced with a flat spring 8. Od35
