Connector, which is connectable with a counter-connector, comprising a connector housing with main contacts, which are connectable to contacts of the counter-connector, a lever, which is arranged between an open position and a closed position on the connector housing and is, starting from the closed position, arranged displaceably into an end position on the connector housing, wherein the lever serves to connect the connector in an insertion direction to the counter-connector by means of displacing the lever, as well as a secondary connector, which has secondary contacts, which are connectable to secondary contacts of the counter-connector, the secondary connector is arranged displaceably between a first position and a second position on the connector housing, characterised in that the lever comprises setting curves, into which setting cams of the counter-connector are insertable and which serve to connect the connector in an insertion direction to the counter-connector by means of displacing the lever from the open position to the closed position, and that the lever is connected to the secondary connector between the closed position and the end position by means of a ramp arrangement, when displacing the secondary connector from the first position into the second position and vice versa, wherein one of the two components, namely lever or secondary connector, has at least one groove, which, in the closed position of the lever, extends at least partially inclined to the insertion direction of the connector, and that the other of the two components, namely secondary connector or lever, has a cam, which engages in the at least one groove, and that the connector housing has two bearing cams and that the lever has two bearing grooves, by means of which the lever is plugged onto the bearing cams and held pivotably relative thereto, so that, when transferring the lever from the closed position to the end position, the connector is not further displaced and the main contacts remain still in contact with each other. a connector housing with main contacts, which are connectable to contacts of the counter-connector, a lever, which is arranged between an open position and a closed position on the connector housing and is, starting from the closed position, arranged displaceably into an end position on the connector housing, wherein the lever serves to connect the connector in an insertion direction to the counter-connector by means of displacing the lever, as well as a secondary connector, which has secondary contacts, which are connectable to secondary contacts of the counter-connector, the secondary connector is arranged displaceably between a first position and a second position on the connector housing, characterised in that the lever comprises setting curves, into which setting cams of the counter-connector are insertable and which serve to connect the connector in an insertion direction to the counter-connector by means of displacing the lever from the open position to the closed position, and that the lever is connected to the secondary connector between the closed position and the end position by means of a ramp arrangement, when displacing the secondary connector from the first position into the second position and vice versa, wherein one of the two components, namely lever or secondary connector, has at least one groove, which, in the closed position of the lever, extends at least partially inclined to the insertion direction of the connector, and that the other of the two components, namely secondary connector or lever, has a cam, which engages in the at least one groove, and that the connector housing has two bearing cams and that the lever has two bearing grooves, by means of which the lever is plugged onto the bearing cams and held pivotably relative thereto, so that, when transferring the lever from the closed position to the end position, the connector is not further displaced and the main contacts remain still in contact with each other.
