Description

ELECTRICAL COUPLING FOR CABLES, FOR VEHICLES ON RAILS Description of the invention The invention relates to an electrical coupling for cables, for rail vehicles, in accordance with the preamble of claim 1. A coupling for cables of this nature is known, for example, through DE 29 22 439 Al. The cable coupling is arranged and guided on a support below the short coupling. The central mechanical stop coupling is configured as a short coupling to be manually engaged, the two coupling halves of which are coupled by means of a stop guide box. In the support, which is constituted by two intermediate plates arranged perpendicular to the axis of the coupling, which are arranged on the left and right of the coupling rod and are connected by two tie rods provide support holes in the intermediate plates for suspend guide bars so that they can move longitudinally. In the intermediate plates, precisely aligned centering members are provided to align the ends of both coupling rods. The ends of the coupling rods have flanges that are overlapped in form and force by the stop guide box. The cable coupling associated with each coupling rod is retained by springs in its uncoupled position which lies behind the front face of the mechanical half of the coupling, and for coupling it can be pushed forward to the coupling position. When coupling the electrical coupling for cables, care must be taken now that the contacts in the perpendicular central longitudinal plane always fit correctly in sight and operation, without the need for additional measures. The coupling contacts for cables at one end of the vehicle arranged to the left and right of this plane are usually on the opposite side at the end of the adjacent vehicle to be coupled. This problem is. solved, for example, when designing the contacts in redundant form, that is, to the left and right of the perpendicular central longitudinal plane, the contacts that have been assigned the same functions are arranged on both sides specularly symmetrical. For couplings for cables that find their application in short couplings that are manually coupled it is necessary to try to provide couplings for small and light cables that can be coupled and uncoupled quickly and easily. However, the reduction in weight and size of the construction depend to a large extent on the number of contacts that must be accommodated in the contact carrier. It also seems unjustified the expense that is currently incurred for two longitudinally displaceable complete halves of the cable coupling, when in the case of short couplings that can only be coupled manually there is no advantage in this case of saving personnel and time, in comparison with the operation of fully automatic central stop couplings. A similar cable coupling having the same disadvantages is also known from DE 41 34 322 A1. The object of the invention is to improve a coupling for low-type cables. consideration so that redundant contact arrangement, arranged symmetrically with respect to the perpendicular central longitudinal plane of the coupling rod, and that the complete cable coupling can be designed more simply and lightly can be avoided. This task is solved by the cable coupling characterized in claim 1. Suitable improvements are indicated in the subordinate claims 2 to 5. The advantage of the coupling for cables according to the invention compared to the state of the art consists in particular in which only one compact adapter box for electrically coupling two vehicles is sufficient, instead of two coupling halves for longitudinally movable cables. By means of the fact that the adapter box contains components, in particular connection lines that are arranged and associated inside the adapter box in such a way that a correct coupling of sight and operation results to the connection cables of both vehicles on rails a coupling, double execution of the arrangement of contacts is avoided, otherwise necessary. By means of the bipartite configuration of the longitudinal guide on both sides of the coupling separation point, an axial longitudinal displacement at the discretion of the adapter box on both sides of the coupling separation point, as well as a central arrangement below, is possible. above or at discretion in the plane of the coupling separation point of the central stop coupling. By providing a locking device in the area of the coupling separation point, a safe positioning of the adapter box during operation is ensured, while the lock to ensure the displaced position allows maneuvers of the vehicle without the adapter box being able to be moved. slip involuntarily from the longitudinal guide, and possibly be damaged when being dragged. By forming a space between both sides of the linear guide in the plane of the coupling, damage to the longitudinal guide is safely prevented by joining the coupling halves of the mechanical coupling. For the purpose of repairs, and in particular if an adapter box is provided in both of the two coupling halves of the mechanical coupling, it is convenient if one of the two can be completely disassembled from the longitudinal guide. The invention is explained below in greater detail on the basis of an exemplary embodiment with reference to the drawing. They show: FIG. 1 a side elevation view of a cable coupling according to the invention in which the central stop coupling is coupled and the adapter box is located below the coupling separation point; 2 shows a side elevational view of the adapter box in a displaced position, with the associated mechanical central stop coupling; 3 shows the arrangement according to FIG. 2 in front view of the adapter box with the associated mechanical central stop coupling; 4 shows a schematic representation of the adapter box in plan view in partial section with internal connecting lines crossed. A cable coupling for vehicles on rails shown in more detail in FIGS. 1 to 4 is retained so that it can be longitudinally displaced in a mechanical central stop coupling, in particular in what is known as a short coupling, and comprises a 1 adapter box compact longitudinally displaceable. The coupling of the connection cables 2 from the adapter box 1 to the two rail vehicles to be coupled is carried out by means of plug-in connections that are not subject to confusion or of fixed cables with at least one plug-in connection 3 respectively. The adapter box 1 contains, cross-arranged within the adapter box 1, the electrical connection lines 4 necessary for the correct coupling of sight and operation to the connecting cables 2 of the vehicles on rails to be coupled, in such a way that a connection cable 2 arranged to the left of the perpendicular longitudinal central plane and associated with one end of the adapter box 1 is arranged at the opposite end of the adapter box 1 in a mirror-symmetric manner to the right of the perpendicular longitudinal central plane, and A connecting cable 2 arranged to the right of the longitudinal central perpendicular plane is correspondingly arranged to the left at the other end of the adapter box 1. The possibility of displacing the adapter housing 1 longitudinally is carried out by means of a longitudinal guide (linear guide) two-part, which is preferably arranged below the mechanical coupling. The first part 5a of the longitudinal guide 5 is associated with the first central stop coupling 6a, and the second part 5b of the longitudinal guide 5 is associated with the second central stop coupling βb of the adjacent vehicle to be coupled and fixed thereto. By this configuration it is possible both a longitudinal displacement at the discretion of the adapter box 1 on both sides of the coupling separation point, as well as the arrangement in the coupling plane, in particular under the coupling coupling separation point. 6a, 6b of central stop. The adapter box 1 is provided with a locking device 7 for securing the central position at the coupling separation point and / or the positions displaced on the respective central stop couplings 6a, 6b. This can be done, for example, by means of latches or latching elements arranged on the coupling rods of the central stop couplings 6a, 6b, to which corresponding counterparts are associated in the adapter box 1. Both parts 5a, 5b of the longitudinal guide 5 are slightly retracted with respect to the perpendicular plane of the coupling point and, in the coupled position of the central stop couplings 6a, 6b form a space 8 to prevent damage to the guide 5. longitudinally axially engaging the central stop couplings 6a, 6b. For the cases of repairs, or in case there is an adapter box 1 in both central stop couplings 6a, 6b to be coupled, the adapter box 1 and the longitudinal guide 5 are designed in such a way that the box 1 adapters in If necessary, it can be completely removed from the longitudinal guide 5. The coupling process is carried out by manually joining the central stop couplings 6a, 6b. In the case of the type of coupling described in the example of embodiment and also indicated in the state of the art, the coupling is carried out by means of a stop guide box 9. An adapter box 1 which is located in a central stop coupling, for example the coupling 6b, moves on the longitudinal guide 5 towards the coupling separation point, and preferably is arranged symmetrically with respect to the coupling separation point. The adapter box 1 is fixed in this position by the blocking device 7. Next, the second connection cable 2 of the vehicle to be coupled to the second side of the adapter box 1 is connected via the plug-in connection 3. If at the coupling point there are 1 adapter boxes in both central stop couplings 6a, 6b, one can be removed from the longitudinal guide 5 by pulling it, and it can be stored. This remaining connection cable 2 is now connected to the remaining adapter box 1. The decoupling process proceeds analogously in order of inverse succession with comparable stages. Before the mechanical uncoupling, the adapter box 1 moves on the longitudinal guide 5 towards the mechanical coupling of the vehicle, and there it locks.

The connecting cables 2 to the other vehicle remain in the other vehicle or can be unplugged, in the case that a plug-in connection 3 has been provided. The invention can also be used for cable couplings that also or only need to connect light wave conductors, for example fiberglass cables. This type of conductors are included within the concepts of electrical coupling for cables, connection cable 2 or connection line 4. It is also possible to communicate the pneumatic ducts of two vehicles for the purpose of compliance of the invention, by means of a modified adapter box 1.
