Abstract: A plug connector with a housing that has at least one conductor insertion opening for inserting an electrical conductor from a conductor insertion direction, a conductor clamping device is accommodated in the housing, and at least one housing exterior wall of the housing is designed to have a snap-on contour for snapping onto a holding element. A first receiving groove has a holding portion which is suitable for receiving a holder of the holding element. The housing exterior wall has a second receiving groove with a longitudinal extent greater than a transverse extent. The second receiving groove is suitable for receiving a latch of the holding element. The second receiving groove has counter-latch which interact with the latch of the holding element, and the longitudinal extent of the first receiving groove and the longitudinal extent of the second receiving groove are substantially parallel.

Abstract: A plug connector of an electrical plug connection, the electrical plug connection including a mating connector to which the plug connector can be plugged in a plug-in direction. The plug connector has a housing and electrical plug contacts, which are arranged at least partially in the housing and are arranged side by side in a series direction. A first housing wall of the housing, which is arranged parallel to a plane spanned by the plug-in direction and the series direction, adjoins a second housing wall. The normal of the second housing wall points approximately in the plug-in direction and is arranged at an angle to the first housing wall. A third housing wall adjoins the second housing wall. Some of the housing walls may include fastening elements formed as grooves or recesses by which functional elements, such as latches or coding elements, may be attached to the housing.

Abstract: A plug-and-socket connector for an electrical plug-and-socket connection that has the plug-and-socket connector and a mating connector associated with the plug-and-socket connector as a mating part to which the plug-and-socket connector can be attached in a plug-in direction, wherein the plug-and-socket connector has a housing and multiple electrical plug-in contacts that are arranged at least partially in the housing and that are arranged side by side in a row direction, wherein a first housing wall of the housing, which is arranged parallel to a plane spanned by the plug-in direction and the row direction, adjoins a second housing wall of the housing, which faces in the plug-in direction and is arranged at an angle to the first housing wall.
