Abstract

An electric cable coupling for rail-borne vehicles is held longitudinally displaceably on a central buffer coupling. The cable coupling has only one adapter box (1) as a replacement for the two usual cable coupling halves, wherein the connection lines (4) for the functionally correct connection of the connection lines (2) to the rail-borne vehicles in the correct left-right configuration are arranged crossed within the adapter box (1), and the connection of the connection lines (2) to the two rail-borne vehicles to be coupled is performed via confusion-proof plug-and-socket connections (3) or fixed cables with at least one plug-and-socket connection (3) each.

Description

The invention relates to an electrical cable coupling for rail vehicles the preamble of claim 1.

Such a cable coupling is e.g. B. known from DE 29 22 439 A1. The cable coupling is arranged and guided on a carrier below the close coupling. The mechanical middle buffer coupling is a manually connectable close coupling trained, the two coupling halves are connected by a shell sleeve. On the carrier, which consists of two support plates arranged perpendicular to the dome axis consists of the left and right of the coupling rod and by two Tie rods are connected, bearing holes for longitudinal displacement in the support plates Storage of guide rods provided. There are also centering elements flush on the support plates. Align the ends of the two coupling rods intended. The ends of the coupling rods have ridges, which of the Shell sleeve can be gripped positively and positively. Every coupling rod assigned half of the cable coupling is by springs in its behind the End face of the mechanical coupling half lying decoupling position held and can be pushed forward into the coupling position for coupling.

When coupling the electrical cable coupling, note that only the contacts are always coupled correctly and in the correct direction on the vertical central longitudinal plane without any further measures. Arranged to the left and right of this level Contacts of the cable coupling of one vehicle end are at the end to be coupled of the neighboring vehicle usually on the opposite side. This Problem was e.g. B. solved by the fact that the contacts are redundant, that is, the left and right of the vertical central longitudinal plane have the same function Assigned contacts are arranged mirror-symmetrically on both sides. For cable couplings, which are used for manually connected short couplings to strive for small, lightweight cable couplings that are quick and easy to connect and must be uncoupled. Now, however, is the reduction in weight and size strongly dependent on the number of contacts to be accommodated in the contact carrier. The previous effort for two complete, longitudinally displaceable also seems Cable coupling halves not justified if only manually operated Close couplings have the advantage of saving personnel and time compared to Actuation of fully automatic middle buffer clutches, is not given here.

A similar cable coupling is also known from DE 41 34 322 A1 has the same disadvantages.

The invention has for its object a generic cable coupling for To improve rail vehicles so that the redundant, symmetrical to the vertical arrangement of the coupling rod arranged contact arrangement is avoidable and the cable coupling overall easier and easier to train becomes.

This object is achieved by the cable coupling characterized in claim 1.

Appropriate further developments are specified in subclaims 2 to 5.

The advantage of the cable coupling according to the invention over the prior art Technology consists in particular that instead of two on longitudinally displaceable Cable coupling halves only a compact adapter box is sufficient to couple two vehicles electrically. Because the adapter box has components, contains in particular connecting lines that are within the adapter box are assigned and assigned that a side and functionally correct connection of the Connection lines to the two rail vehicles to be coupled is the otherwise necessary, double execution of the contact arrangement can be avoided.

Due to the two-part design of the longitudinal guide on both sides of the coupling disconnection point is both an optional, axial longitudinal displacement of the adapter box on both sides of the coupling separation point as well as a central arrangement below, above or optionally in the level of the coupling separation point of the central buffer coupling is possible.

By providing a lock in the area of the coupling disconnection point, one is secure positioning of the adapter box ensured during operation, while locking to secure the sliding position maneuvering the vehicle enables without the adapter box being unwanted from the longitudinal guide can slide and possibly be damaged when dragging along.

By forming a gap between the two parts of the linear guide in the dome plane there is damage to the longitudinal guide when merging the coupling halves of the mechanical coupling safely avoided.

For repair purposes and especially when on both coupling halves to be coupled an adapter box is arranged for the mechanical coupling, it is useful if one of the two is completely removable from the longitudinal guide.

The invention is based on an embodiment with reference to the Drawing explained in more detail.

A cable coupling for rail vehicles shown in more detail in Figures 1 to 4 is on a mechanical medium buffer coupling, especially a so-called Short coupling, held longitudinally and has a compact, longitudinally movable Adapter box 1 on. The connection of the connecting lines 2 from the adapter box 1 to the two rail vehicles to be coupled is carried out via a mix-up Plug connections 3 or fixed cables with at least one each Plug connection 3. The adapter box 1 contains the necessary electrical connection lines 4 for connecting the connecting cables in the correct side and function 2 to the rail vehicles to be coupled within the adapter box 1 arranged crossed, such that one arranged to the left of the vertical central longitudinal plane and a connecting line 2 assigned to one end of the adapter box 1 at the opposite end of the adapter box 2 mirror-symmetrically to the right vertical median longitudinal plane and one to the right of the vertical median longitudinal plane arranged connection line 2 accordingly at the other end of the adapter box 1 is arranged on the left.

The longitudinal displaceability of the adapter box 1 is brought about by a two-part longitudinal guide (linear guide) 5, which is preferably arranged below the mechanical coupling. The first part 5a of the longitudinal guide 5 is assigned to the first central buffer coupling 6a and the second part 5b of the longitudinal guide 5 is assigned to the second central buffer coupling 6b of the neighboring vehicle to be coupled and fastened thereon.
With this design, both an optional, axial longitudinal displacement of the adapter box 1 to both sides of the coupling separation point and an arrangement in the coupling plane, in particular below the coupling separation point of the central buffer couplings 6a, 6b, are possible.

The adapter box is used to secure the middle position at the coupling disconnection point and / or the displacement positions on the respective middle buffer couplings 6a, 6b a locking device 7 provided. This can e.g. B. by grid or locking elements take place, which are arranged on the coupling rods of the central buffer couplings 6a, 6b are and their corresponding counterparts on the adapter box 1 assigned are.

The two parts 5a, 5b of the longitudinal guide 5 are opposite the vertical plane slightly reset at the coupling disconnection point and form in coupled Position of the middle buffer couplings 6a, 6b a gap 8, so that damage the longitudinal guide 5 avoided in the event of an axial impact of the center buffer couplings 6a, 6b becomes.

For repairs or if both central buffer clutches 6a, 6b are to be coupled an adapter box 1 is present, the adapter box 1 and the longitudinal guide 5 designed in such a way that the adapter box 1 completely from the Longitudinal guide 5 is removable.

The coupling process is carried out by manually connecting the middle buffer couplings 6a, 6b. In the described in the embodiment and also in the state of the Technically specified coupling type is connected by means of a shell sleeve 9.

One on a central buffer coupling, e.g. B. the clutch 6b, existing adapter box 1 is moved to the coupling separation point on the longitudinal guide 5 and preferably arranged symmetrically to the coupling disconnection point. In this situation the adapter box 1 is fixed by means of the locking device 7.

Now the second connecting line 2 is connected to the second side of the adapter box 1 by the vehicle to be coupled by means of plug connection 3.
If adapter boxes 1 are provided on the two central buffer couplings 6a and 6b at the coupling point, one can be pulled off the longitudinal guide 5 and put away. This remaining connecting line 2 is now connected to the remaining adapter box 1.

The uncoupling process is carried out in reverse in comparable steps Sequence. The adapter box 1 is before mechanical decoupling moved on the longitudinal guide 1 for mechanical coupling of a vehicle and locked there. The connecting lines 2 to the other vehicle remain on other vehicle or, if a connector 3 is also provided here is to be deducted.

The invention can also be used for cable couplings which also or only use optical fibers, e.g. B. fiber optic cables should connect. These types of lines are said to the terms electrical cable coupling, connecting line 2 and connecting line 4 be included. It is also feasible to use pneumatic lines for two vehicles according to the subject of the invention via a modified adapter box 1 to connect.
