ASSEMBLY FOR SECURING AN ELECTRICAL EXTERNAL POWER SUPPLY CONNECTOR

Abstract

An assembly secures a connector of an external power supply in a rail vehicle. The connector is enclosed by a housing and by a rotatably mounted flap. The flap and the housing each have a slot configured to receive a catch. The flap can have two positions: a first position, in which the flap covers the connector and thus prevents access to the connector, and a second position, in which access to the connector is possible. The flap supports a lock cylinder, which can be switched by a key into two states: in a first state, the key can be pulled out of the lock cylinder, and in a second state, the key is secured in the lock cylinder against removal. A catch is rotated into both slots or out of both slots by the lock cylinder.

5. A rail vehicle, comprising: electrical external power supply connectors; assemblies, each of said assemblies securing one of said electrical external power supply connectors, each of said assemblies containing: a housing at least partially enclosing a respective electrical external power supply connector of said electrical external power supply connectors, said housing having a slot formed therein for receiving a catch; a flap connected to said housing via a pivot pin such that said flap can rotate between a first position and a second position, wherein, in the first position, said flap at least partially covers said respective electrical external power supply connector and thus prevents access to said respective electrical external power supply connector, and wherein, in the second position, said flap allows access to said respective electrical external power supply connector; a catch; said flap having a lock cylinder with a key, wherein, in a first state of said lock cylinder, said key can be pulled out of said lock cylinder, and wherein, in a second state of said lock cylinder, said key is secured in said lock cylinder against removal, said lock cylinder configured to rotate said catch and is connected thereto; wherein, in the first state of said lock cylinder, said catch completely engages in said slot in said housing in order to lock said flap in the first position; wherein, in the second state of said lock cylinder, said catch is not in engagement with said slot of said housing in order to unlock said flap in the first position and in order to allow said flap to be brought into the second position; said flap having a slot formed therein for receiving said catch, and in the first position of said flap, said slot in said flap corresponds with said slot in said housing in such a way that, in the first state of said lock cylinder, said catch completely engages in said slot in said housing and in said slot in said flap; and in the second position of said flap, said slot in said flap is configured and is disposed with respect to said slot in said housing in such a way that engagement of said catch in said slot in said housing is prevented, with a result that said lock cylinder remains in the second state; and said electrical external power supply connectors are at least two secured connectors and said at least two lock cylinders are configured to be actuated by an identical key, wherein, in an operative mode of the rail vehicle, only exactly one said key for actuating said lock cylinders is provided for operating personnel on the rail vehicle.

6. The rail vehicle according to claim 5, wherein said housing and/or said flap is/are fabricated from steel sheet.

7. The rail vehicle according to claim 5, wherein the rail vehicle is a locomotive.

Description

[0021] The present invention will be described in more detail below by way of example on the basis of a drawing, in which

[0022] FIG. 1 shows the assembly according to the invention with open flap,

[0023] FIG. 2 shows the assembly according to the invention with closed flap, and

[0024] FIG. 3 shows the key components of the assembly according to the invention with open flap.

[0025] FIG. 1 shows the assembly according to the invention with open flap KL.

[0026] A connector ANS, which is provided on the rail vehicle (not shown) as part of an external power supply FES, is at least partially enclosed by a housing GEH.

[0027] The housing GEH has a slot SGEH for receiving a catch, which is shown later.

[0028] A flap KL is connected to the housing GEH via a pivot pin DA, with the result that the flap can be rotated between a first position (closed position) which is shown later, and the second position (open position), which is shown here.

[0029] In the second position of the flap KL that is shown here, access to the connector ANS of the external power supply FES, for example by operating personnel, is possible.

[0030] The flap KL has a lock cylinder SZ, which is described in more detail later and which can be brought by means of a key (not shown here) into various states.

[0031] In anticipation of and with reference to FIG. 2, the key can be pulled out of the lock cylinder SZ in a first state of the lock cylinder SZ.

[0032] In FIG. 1, the lock cylinder SZ is situated in a second state in which the key is secured in the lock cylinder SZ against removal and can thus not be pulled out.

[0033] The lock cylinder SZ is connected to a catch SPE and is designed to rotate the catch SPE.

[0034] The flap KL has a slot SKL for receiving the catch SPE.

[0035] In the second position of the flap KL (open position) that is shown here, the slot SGEH in the housing GEH is arranged with respect to the slot SKL in the flap KL in such a way that engagement of the catch SPE in the slot SGEH in the housing GEH is prevented.

[0036] As will be described in more detail below, the key can thus not be pulled out of the lock cylinder SZ in this position of the flap KL.

[0037] FIG. 2 shows, with reference to FIG. 1, the assembly according to the invention with closed flap KL.

[0038] Here, the flap KL is brought via the pivot pin DA into the first position (closed position), in which the flap KL at least partially covers the connector ANS shown in FIG. 1 and thus prevents access to the connector ANS.

[0039] In this position, the here concealed lock cylinder (FIG. 1, SZ) can have either a first state, in which the key can be pulled out of the lock cylinder, and the second state, in which the key is secured in the lock cylinder (FIG. 1, SZ) against removal.

[0040] Here, the lock cylinder (FIG. 1, SZ) is situated in the first state: the catch SPE completely engages both in the slot SGEH in the housing GEH and in the slot SKL in the flap KL. The flap KL is thus locked in this first position.

[0041] In order to achieve this, in the first position of the flap KL, the slot SKL in the flap KL corresponds in its configuration and in its position with the slot SGEH in the housing GEH such that, in the first state of the lock cylinder, the catch SPE completely engages in both slots SKL, SGEH.

[0042] For the sake of completeness, there will be briefly discussed the second state (which is not shown here) of the lock cylinder that is achieved by rotating the key:

[0043] The catch SPE would then be rotated and would not engage in the two slots SGEH and SKL, the flap KL would be unlocked in the first position and could be brought into the second position (open position).

[0044] FIG. 3 shows, with reference to FIG. 1 and FIG. 2, the key components of the assembly according to the invention with open flap KL.

[0045] The flap KL is here in the second position, with the result that access to the connector is possible.

[0046] The flap KL has the lock cylinder SZ, wherein, in this position of the flap KL, as a result of the position and arrangement of the slots SGEH and SKL, the lock cylinder SZ is situated in the second state—i.e. the associated key is secured in the lock cylinder SZ against removal.

[0047] In this second position of the flap KL, the slot SKL in the flap KL does not correspond with the slot SGEH in the housing GEH—the two here at best only partially overlap, with the result that engagement of the catch SPE in the slot SGEH in the housing GEH is prevented.

[0048] By virtue of this blocking of the catch SPE, the lock cylinder SZ remains in the second state, with the result that the associated key is secured against removal.
