Electrical contact coupling device for rail vehicles

6. Known protective covers for mating electrical contact couplings and mating electrical contact couplings to be coupled to them that are automatically opened synchronously by contact with each other, the corresponding protective covers passing through A spring device which is arranged on the outside on the electrical contact coupling or on the housing of the mating electrical contact coupling and is hinged to the corresponding protective cover is held in the closed position. When the protective cover of the electrical contact coupling to be connected and the protective cover of the mating electrical contact coupling are moved together, the spring is overcome when the protective covers come into contact with each other by rolling the surfaces of the protective covers against each other. The device realizes opening. However, the conventionally exposed spring elements of the actuating device for moving the cover can be damaged or lost, especially when the protective flap is closed, due to raised gravel or the like and thereby significantly impair the function of the actuating device.

7. In order to improve the synchronization of the opening and to prevent slippage, such an automatic protective cover is provided, for example, with rubber elements on the end side of the contact-fit coupling, which serve to increase the electrical contact-coupling with the counterpart. Friction or a certain form fit occurs when the end sides of the protective cover of the connecting device come into contact. These rubber parts are fixed to the protective cover by gluing or riveting, and the rubber parts are usually extruded profiles or mats. The disadvantage of this solution is that, in the case of a protective cover that is bent around several axes, these components are difficult to fasten or a specially produced profile must be produced for this, which entails additional tooling costs.

8. Therefore, the technical problem to be solved by the present invention is to provide an improved electrical contact coupling device for an automatic center buffer shock coupling device of a rail vehicle, which is characterized by a non-disturbing Open and re-cover the interface unit. In this case, by eliminating the disadvantages of the prior art, it should be possible to open the protective covers of the electrical contact couplings to be connected to one another in a synchronized manner without interference. In particular, electrical contact couplings and central buffers for rail vehicles are provided.
