## Abstract

The present invention relates to an electric plug-in connection, in particular for electric vehicles. Said plug-in connection is equipped with a plug-in connector (1, 2) substantially consisting of a socket (1) and a plug (2). The connection is also provided with a locking unit (4, 5) comprising at least one blocking element (4) and a transmission element (5) for detachably coupling the socket (1) and the plug (2). Further, an actuator (8) is provided, for actuating the transmission element (5) together with the blocking element (4) arranged at one end thereof. According to the invention, the transmission element (5) is in the form of a gear arrangement (5).

## Claims

### Claim 1

An electric plug-in connection comprising a socket for receiving a plug;
the electric plug-in connection further including:
a locking unit for automatic locking of the socket and the plug, the locking unit comprising a blocking element having a gear rod section and a transmission element built as a gear arrangement, the blocking element arranged at a first end of the transmission element; and
an actuator for actuating the locking unit when the actuator is electrically actuated,
wherein the actuator is arranged at a second end of the transmission element opposite the first end and causes a first linear movement which is translated into a second linear movement perpendicular to the first linear movement via the blocking element.

### Claim 2 (depends on 1)

The plug-in connection according to claim 1, wherein the gear arrangement is a deflection gear and/or a transmission/reduction gear.

### Claim 3 (depends on 1)

The plug-in connection according to claim 1, wherein the gear arrangement is acted upon by a drive journal of the actuator.

### Claim 4 (depends on 1)

The plug-in connection according to claim 1, wherein the blocking element is a locking journal.

### Claim 5 (depends on 3)

The plug-in connection according to claim 3, wherein the drive journal contains a gear rod section.

### Claim 6 (depends on 3)

The plug-in connection according to claim 3, wherein the drive journal and the blocking element are arranged at a right angle to each other.

### Claim 7 (depends on 3)

The plug-in connection according to claim 3, wherein the drive journal and the blocking element are connected by at least one gear wheel as a drive means.

### Claim 8 (depends on 1)

The plug-in connection according to claim 1, wherein the gear arrangement is arranged in a housing.

### Claim 9 (depends on 8)

The plug-in connection according to claim 8, wherein the housing comprises a support part and a cover part.

### Claim 10 (depends on 8)

The plug-in connection according to claim 8, wherein at least one seal is provided between the two housing parts.
