Description

one

The invention relates to electrical engineering, in particular, to devices for controlling switching devices of electrical circuits.

Devices are known for controlling three switching devices, comprising a drive mechanism associated with switching devices 1.

The closest in technical essence to the invention is a device for controlling switching devices, comprising a housing in which switching devices connected to a drive mechanism 2 .15 are installed in a row.

However, the known devices have a complex structure and do not allow sequential switching of several switching devices arranged in a row.

To simplify the design of the device in the proposed device for controlling switching devices, comprising a housing in which p. For the installation of the switching devices connected to the drive mechanism, the body has supports with bevels and a guide, and the drive mechanism consists of a tie-rod with a holder installed with the possibility of

Bone reciprocating movement in the guide casing, and a spring-loaded liner with bevels and a notch, alternately interact with switching devices, with the bevels of the spring-loaded liner facing the bevels of the hull supports.

Figures 1-5 illustrate the proposed device for controlling switching devices.

A device for controlling switching and switching devices is carried out in housing 1, in which rows 2 of switching devices and wedge-shaped support lugs 3 are sequentially arranged with bevels 4 on the bearing surface. In guides 5 of housing 1, the driving bar is arranged for reciprocating movement - a leash 6, at the end of which the holder 7 is fastened with a spring-loaded compression spring 8 - the insert 9 of the wedge-shaped profile having a recess 10 for gripping the end of the lever-handle 11 of the switching device 2. Slopes 12 cam claws 9 and support lugs 3 are made with equal slopes and counter direction.

When the drive is turned on, the drive strip 6 begins to move in the guides 5, the holder 7 moves together with it, and the insert-cam 9 and the spring 8 move in it. At the time the insert 9 between the projections 3 is located, it is under the action of the spring 8 its lower position and the edges of the recess 10 clasps the end of the lever-handle 11. Upon further movement, the insert-cam 9 moves the lever 11 to a new working position and with its skew 12 slides over the bevel 4 of the protrusion 3, thereby raising the spring 8. End of ru About 11 is released, the exit from the recess 10. Having reached its upper position, the insert-cam 9 passes over the end of the handle 11, not setting it (steps over the handle 11) and slipping on the supporting surface of the protrusion 3 until will occur between the following support protrusions 3. At this moment, the insert-cam 9 under the action of the spring 8 is again lowered, grabs the end of the handle of the next switching device with its notch 10, and the whole control process of switching of the latter is repeated). So A And

In the same way, switching control of switching devices 2 is controlled when the driving strip of the driver moves in the opposite direction.
