Electrical contact coupling device for rail vehicle and method of making central buffer shock coupling device

Electrical contact couplings and center shock couplings for rail vehicles

1. The present invention relates to an electrical contact coupling device for an automatic center buffer shock coupling device for rail vehicles. The present invention also relates to a center buffer strike coupling device for rail vehicles.

2. Conventional electrical contact couplings for automatic center bumper couplings for rail vehicles are usually arranged adjacent to the mechanical contact couplings of the center bumper couplings and have a coupling housing in which An interface unit with a plurality of connecting elements is arranged in the coupling device housing. The electrical contact coupling also has a protective cover for covering the access for access to the connection elements of the interface unit. The protective cover is connected to an operating device for moving the protective cover between a first position in which the protective cover covers the entrance and a second position in which the protective cover opens the entrance.

3. Patent document ep 11 02 696 b1 discloses an electrical contact coupling device for an automatic center-buffering coupling device for rail vehicles. The electrical contact coupling has a contact carrier that can be fastened on the coupling head and that can be guided in translation in the longitudinal direction of the central shock-absorbing coupling, the contact carrier having for the electrical connection and the contact carrier is movable from an uncoupled position at the rear to a position at the front ready for coupling.
