阅读说明：本技术 用于保护电气的外部供电接头的装置 (Device for protecting an electrical external power supply connection ) 是由 N.雷辛 M.施韦林 M.泽尔特纳 于 2019-07-09 设计创作，主要内容包括：本发明涉及一种用于保护轨道车辆中的外部供电的接头的装置。该接头至少部分地被壳体和可旋转地支承的翻盖包括。翻盖和壳体分别具有缝隙,该缝隙构造用于容纳锁扣。翻盖可以具有两个位置：第一位置和第二位置,在第一位置中翻盖至少部分覆盖接头并且以此抑制动用接头,在第二位置中实现动用接头。翻盖支承锁芯,锁芯通过钥匙可以切换到两个状态中,在第一状态中钥匙可以从锁芯中拔出,在第二状态中钥匙在锁芯中受保护以防取出。利用锁芯将锁扣转动到两个缝隙中以及从两个缝隙中转出。在翻盖的第一位置中,翻盖的缝隙与壳体的缝隙相吻合,使得在锁芯的第一状态中锁扣完全咬合到两个缝隙中并以此锁定翻盖。在翻盖的第二位置中翻盖的缝隙这样构造和布置,使得锁扣在壳体的缝隙中的咬合被抑制,使得锁芯留在第二状态中。(The invention relates to a device for protecting an externally supplied electrical connection in a rail vehicle. The joint is comprised at least in part by a housing and a rotatably supported flip. The flip cover and the housing each have a slot configured to receive the latch. The flip cover can have two positions: a first position in which the flap at least partially covers the connector and thereby inhibits the movable connector, and a second position in which the movable connector is enabled. The flap supports a lock cylinder which can be switched by means of a key into two states, a first state in which the key can be removed from the lock cylinder and a second state in which the key is protected in the lock cylinder against removal. The lock cylinder is used to rotate the lock catch into and out of the two slots. In the first position of the flap, the slot of the flap coincides with the slot of the housing, so that in the first state of the lock cylinder the catch engages completely into both slots and thus locks the flap. In the second position of the flap, the slot of the flap is designed and arranged in such a way that the latching of the catch in the slot of the housing is suppressed, so that the lock cylinder remains in the second state.)

1. A device for protecting an electrical external power supply connection on a rail vehicle,

-wherein the joint is at least partially surrounded by a housing and the housing has a slit for accommodating a catch,

wherein the flap is connected with the housing by a rotational axis such that the flap is rotatable between a first position and a second position, wherein in the first position the flap at least partially covers the joint and thereby prevents access to the joint, and wherein in the second position the flap enables the joint to be accessed,

wherein the flap has a lock cylinder with a key, wherein the key can be pulled out of the lock cylinder in a first state of the lock cylinder, and wherein the key in the lock cylinder is prevented from being removed in a second state of the lock cylinder,

wherein the lock cylinder is configured for rotating and connecting with the lock catch,

wherein in the first state of the lock cylinder the catch is completely engaged in the aperture of the housing to lock the flap in the first position,

wherein in the second state of the lock cylinder the catch is not engaged with the aperture of the housing in order to unlock the flap in the first position and to effect a change of the flap into the second position,

it is characterized in that the preparation method is characterized in that,

the flap has a slot for receiving the catch,

in the first position of the flap, the slot of the flap coincides with the slot of the housing, so that in the first state of the lock cylinder the catch engages completely in the slot of the housing and in the slot of the flap,

and is

In the second position of the flap, the slot of the flap is configured and arranged relative to the slot of the housing in such a way that the latching of the latch in the slot of the housing is suppressed, so that the lock cylinder remains in the second state.

2. The device of claim 1, wherein said housing and/or said flip is made of steel plate.

3. The apparatus of claim 1 or 2, wherein the rail vehicle is a locomotive.

4. A rail vehicle having at least two electrical external power supply terminals,

-wherein the external power supply connection is protected according to claim 1 or 2,

wherein at least two lock cylinders are configured for being operated by the same key,

in this case, only exactly one key for actuating the lock cylinder is assigned to the operator on the rail vehicle during operation of the rail vehicle.
