- the time at which the two plug-in components of the first and second part of the connecting device are connected to one another corresponds to the time at which the connection of the control line (s) is established or are, the test position.
- the second part of the connecting device has at least one pressure device, by means of which the connection of the second part to the first part of the connecting device can be produced.
- the printing device is preferably at least partially part of the movable component of the second part of the connecting device and particularly preferably has a stop and a movable counter-stop, with the stop and the counter-stop resting next to one another in the rest position of the printing device.
- the stop of the printing device is preferably designed as an elevation and this is particularly preferably cuboid.
- the counter-stop of the printing device preferably has at least one roller lever and a spring element, with the spring element particularly preferably being designed as a gas spring.
- the stop by means of the action of a compressive force on the counter-stop of the printing device, the stop can be overcome by the counter-stop and by means of the compressive force with which the stop of the printing device can be overcome by the counter-stop, there is preferably a counter pressure on the plug connection components of the first and second part of the connecting device can be exercised, by means of which the connection of the second part to the first part of the connecting device can be established.
- a mechanism for example on a trolley, in particular a counter trolley, or in a drawer or a slot, etc. , installed, which when pressure is exerted on the counter-stop of the pressure device of the second part of the connecting device by pushing in, for example the carriage, starting from the rest position of the pressure device, when connecting stop and counter stop next to each other or Depending on the requirements, they can also rest against each other, which ensures the generation of sufficient back pressure in order to establish the plug connection of the connecting device and thus the connection of the control line (s) safely and stably.
- a gas spring or This is further improved with a gas pressure spring.
- the use of a roller lever causes the further retraction or Insert, the movable component can move further towards the control cabinet to the end position without counter pressure, while the connection of the control line(s) continues.
- the roller lever moves after leaving or Overcoming the vertical surface, for example on the cuboid elevation along the horizontal top surface of the elevation or. of the attack.
- the length of the possible movement can be dimensioned depending on the requirements. If there is a correspondingly long air gap for a safe separation of contacts, especially main contacts, required parts or required, the corresponding length can easily be extended to at least 90mm or even significantly longer.
