The invention relates to devices for providing electrical contact in a detachable connection of an electrical circuit controlling the operation of the electropneumatic brakes of the rolling stock.

The purpose of the invention is to increase reliability.

The drawing shows the device, a general view.

into the housing with simultaneous compression of the springs 4 and 6. After reaching the predetermined position of the heads and fixing them with special locks, the contact fingers are aligned with each other and are mutually pressed by the spring. At the point of contact of the first contact fingers 5, an annular contact surface is formed, along which

The device closes the electrical circuit. The device contains two identical nodes. IQ The second contact zone is formed inside

the finger cavities 5 with the second contact fingers 7. The fingers 7 are pressed by the springs.

The heads of the connecting sleeves, in the tides of which contact devices are mounted, each of which includes a housing 1 in which an insulating gasket 2 and an insulating bushing 3 are mounted, covering the spring-loaded spring 4 relative to the insulating gasket 2, the first conductive contact pin 5 with a spherical contact surface, in the axial hole of which a spring 6 and a second conductive contact finger 7 with a spherical contact surface are placed.

The device works as follows.

With the introduction of the fopMO3Hbix heads of the connecting sleeves in engagement, the electrical contact nodes move relative to one another. When this happens, the movement of the contact fingers 5 and 7

into the housing with simultaneous compression of the springs 4 and 6. After reaching the predetermined position of the heads and fixing them with special locks, the contact fingers are aligned with each other and are mutually pressed by the spring. At the point of contact of the first contact fingers 5, an annular contact surface is formed, along which

The device closes the electrical circuit. The second contact zone is formed inside

the finger cavities 5 with the second contact fingers 7. The fingers 7 are pressed by the springs.
