Abstract
The invention relates to a locking system for a plug coupling device and to a plug coupling device having a housing in which the locking system according to the invention is arranged. A plug having a projection, which may for example be a guide pin of a commercially available safety plug, can be coupled to the plug coupling device by means of the locking system according to the invention, wherein a locking device in the form of a slider engages behind the projections of the plug such that the plug coupled to the plug coupling device cannot be removed from the plug coupling device. In addition, the locking device being in the locking position prevents an unauthorized insertion of a plug into the plug coupling device.
Claims20
Locking system for a plug coupling device (100) which can be coupled with a plug (10) having at least two projections (11, 11′), comprising:
- a locking device (20) for locking the plug (10) with the plug coupling device (100);
- a drive device (30, 31, 40, 41) for moving the locking device (20) between an unlocked position in which the plug (10) can be coupled with the plug coupling device (100), and a locked position in which the plug (10) coupled with the plug coupling device (100) is locked;
- the drive device (30, 31, 40, 41) comprising a drive shaft (31) and a transmission (40, 41) between the drive shaft (31) and the locking device (20), characterised by the following features:
- the locking device (20) comprises a first strut (21, 22) and a second strut (21, 22) with spacing therefrom, the two of which extend mutually parallel in the movement direction of the locking device (20) and are interconnected by a material web (23);
- and
- two projections (11, 11′) of the plug (10) are engaged from behind by the first strut (21, 22) and the second strut (21, 22) when the locking device is in the locked position, so that the plug (10) coupled with the plug coupling device (100) cannot be removed from the plug coupling device (100).
