Patent ID: 8662906

Claim:
A plug-and-socket connector, comprising: a first housing with first electrical contacts; and a second housing with second electrical contacts, the first housing having a lever which is rotatably mounted on the first housing, the second housing having a toothed surface on which the lever can be brought into contact with the toothed surface, with the lever acting with the toothed surface upon pivoting the lever from a pre-engagement position into the end position and drawing the first and the second housing together into the end position in which the first and the second contacts are contacted with each other, the lever having a contact surface, the first housing having a blocking surface on a blocking element, in a pre-assembly position of the first and the second housing in which the two housings are partially inserted into one another, the blocking surface being arranged in a path of movement of the contact surface of the lever from the pre-engagement position towards the end position of the lever, so that pivoting of the lever into the end position is blocked, the second housing having a release surface, upon pushing together the two housings from the pre-assembly position into an assembly position the release surface moving the blocking element with the blocking surface out of the path of movement of the contact surface, so that the lever can be moved from the pre-engagement position into the end position in order to assemble the two housings into the assembly position.
