The invention relates to an expansion connection arrangement for adjoining power rails (20, 20') of an overhead line system for electric locomotives. The power rails (20, 20') to be connected are arranged spaced apart from one another here at a joint distance (s) and each have a contact wire (10, 10') along which a current collector of a locomotive vehicle can slide for the purpose of transmitting energy. According to the invention, a connection profile (50) is connected to the one power rail (20), and a corresponding profile (50') is connected to the other power rail (20'). The connecting profile (50) and the corresponding profile (50') engage one in the other in a positively locking fashion such that they can slide one into the other in the direction of the contact wire (10 and 10', respectively) and are locked transversally with respect thereto. Each of the power rails (20, 20') is respectively connected to a half rail (60, 60') assigned thereto, which half rails (60, 60') support the contact wires (10, 10') between the power rails (20, 20') with the connection profile (50) and the corresponding profile (50'), respectively, and secure them parallel to one another at a defined contact wire distance (d) over an overlapping length (1). As a result, an expansion connection arrangement is made available which is low in weight, compensates large expansion lengths and has good override properties. |
